Local advertising regulation: the signage authorisation that determines whether a commercial asset can be operated

A commercial asset is worth no more than its visibility. A ground-floor unit let to a national retailer, a retail park on the outskirts, a ground floor on a Parisian shopping street: in each case, the capitalised rental value rests on the implicit assumption that the tenant will be able to signal its business on the façade, in the dimensions and by the means that match its operating standards. That assumption cannot be taken for granted. The municipality's local advertising regulation (règlement local de publicité, RLP) may make the installation of signage subject to authorisation, tighten its dimensions, prohibit illuminated devices, and render non-compliant signs that have been in place for years. This guide addresses the subject from the standpoint of the institutional landlord and the retail investor: what the RLP prohibits even before the lease is signed, who is legally the applicant for the signage authorisation, how to allocate the burden of compliance in the contract, and who actually bears the daily penalty (astreinte) and the costs of enforcement works carried out by the authority when the municipality acts.

What the local advertising regulation adds to the national regulation

The RLP is a local document which, subject to Articles L. 581-4, L. 581-8 and L. 581-13 of the French Environmental Code, defines one or more zones in which a regulation more restrictive than the requirements of the national regulation applies (Art. L. 581-14 of the Environmental Code). It is drawn up by the public inter-municipal cooperation body responsible for local urban planning (plan local d'urbanisme), by the Lyon metropolitan authority or, failing that, by the municipality. Its logic runs one way only: it can only tighten the national constraints, never relax them. For an investor, this means that the national regulation is no more than a floor, and that the acquisition decision must be made on the basis of the local text.

The RLP may also define zones in which every occupier of a commercial unit visible from the street or, failing an occupier, every owner must ensure that the external appearance of that unit does not harm the character or interest of the surrounding area. The wording matters for a landlord: it expressly designates the landlord, in the alternative, when the unit is vacant. An asset between two tenants is therefore not a neutral asset as far as the policing of signage is concerned.

Drafting procedure and the window for challenge

Since 26 May 2026, the date on which Article 1 of Law No. 2025-1129 of 26 November 2025 entered into force, Article L. 581-14-1 of the Environmental Code refers to the procedures for drawing up, revising and modifying local urban planning documents set out in Title V of Book I of the French Town Planning Code, with the exception of the transitional provisions of Chapter IV of Title VII of the Town Planning Code. The express exclusion of the simplified modification procedure that appeared in the earlier wording has disappeared. These provisions do not apply to procedures for amending a territorial coherence scheme (schéma de cohérence territoriale) or a local urban planning document that were under way on that date.

Before the public inquiry, the draft as adopted is submitted for an opinion to the departmental commission responsible for nature, landscapes and sites, an opinion that is deemed favourable if it has not been given within three months. Once approved, the RLP is appended to the local urban planning document or the documents that take its place; where there is no urban planning document, it is made available to the public.

The point that every investor must retain is the bar on challenge:

Illegality on grounds of defective form or procedure committed in the course of drawing up, revising or approving a local advertising regulation may not be raised by way of exception once a period of six months has elapsed from the entry into force of that regulation.

This time bar does not apply where the procedural defect consists of a substantial disregard of, or a manifest breach of, the rules governing the public inquiry. In practical terms, the strategy of waiting for a compliance order and then challenging the regularity of the RLP by way of exception is closed after six months. Monitoring RLP procedures in the municipalities where one holds retail property is therefore an asset management matter, not a matter of deferred litigation.

The national baseline that the RLP may tighten

Three substantive requirements structure most façade decisions, and should be read as a national maximum that may be reduced locally.

• Surface area: signs affixed to a commercial façade may not have a cumulative surface area exceeding 15% of the surface area of that façade, a figure that may be raised to 25% where the commercial façade of the establishment is under 50 square metres (Art. R. 581-63 of the Environmental Code). Shop windows count towards the reference surface area.
• Projection: signs affixed flat against a wall or parallel to a wall must not extend beyond the limits of that wall or project from it by more than 0.25 metres (Art. R. 581-60 of the Environmental Code).
• Ground-mounted signs of more than 1 m²: a minimum distance of 10 metres from a window of a building on neighbouring land where they stand in front of the plane of the wall containing that window, siting at a distance from a boundary at least equal to half their height, and a limit of one device per public thoroughfare running alongside the building (Art. R. 581-64 of the Environmental Code).

The regime for illuminated signs was tightened by Decree No. 2023-1409 of 29 December 2023, in force since 1 January 2024. Article R. 581-59 now refers to thresholds of average luminance not to be exceeded, expressed in candelas per square metre, and to the luminous efficacy of the sources used, according to technical standards set by ministerial order. Illuminated signs are switched off between 1 a.m. and 6 a.m. when the business signalled has ceased trading; where a business ceases or begins trading between midnight and 7 a.m., switching off takes place no later than one hour after the business ceases and switching on may precede the resumption of business by one hour. Flashing signs are prohibited, with the exception of pharmacy signs or those of any other emergency service.

The RLP may go further, including inside the unit: by derogation from Article L. 581-2, Article L. 581-14-4 allows the RLP to subject illuminated signs located inside the display windows or bays of a commercial unit, and intended to be visible from a public thoroughfare, to requirements on switch-off times, surface area, energy consumption and the prevention of light nuisance. Window screens, LED strips and shopfront communication devices therefore fall, in those municipalities, under the same penalty regime as the sign on the façade.

Signage authorisation: when it is required and who applies for it

The most frequent error is to reason as if every sign were subject to authorisation everywhere, or conversely as if a simple declaration were enough. The text is precise. Article L. 581-18, paragraph 4, of the Environmental Code provides:

On buildings and in the places referred to in Articles L. 581-4 and L. 581-8, as well as within the framework of a local advertising regulation, the installation of a sign is subject to authorisation.

Signage authorisation is therefore triggered either by the nature of the place or by the existence of an RLP. The same article adds, in its wording in force since 1 January 2024, that signs using a laser beam are subject to the mayor's authorisation.

The legal applicant is the operator, not the owner

Article R. 581-9 of the Environmental Code, in the wording resulting from Decree No. 2025-1354 of 26 December 2025, in force since 1 July 2026, settles the question of standing: Where the installation of a sign is subject to authorisation under Article L. 581-18, the application for authorisation is made by the person or undertaking carrying on the business signalled. The applicant is the tenant operating the business. The landlord cannot take its place, but it can, and must, organise its cooperation by contract.

The application and the file accompanying it, prepared in three copies, are sent by registered post with postal acknowledgement of receipt, sent electronically, or lodged at the town hall of the municipality where the installation is planned. The application is made on a form specified by order of the minister responsible for the environment.

A widespread confusion should be dispelled here. Article L. 581-24 of the Environmental Code, under which no one may affix advertising or install a pre-sign (préenseigne) on a building without the written authorisation of the owner, applies only to advertising and pre-signs. The landlord's consent to the tenant's sign does not find its basis in that provision: it comes from the commercial lease, and from the lease alone. Hence the importance of the clause.

Processing times and tacit authorisation

Since 1 July 2026, Article R. 581-13 of the Environmental Code provides that the competent authority rules on the application within two months of receipt at the town hall of a complete file. The file is deemed complete if the competent authority has not, within one month of receipt of the file at the town hall, notified the applicant of the list of missing documents under the conditions laid down in Article R. 581-10-1. The decision is notified by registered post with acknowledgement of receipt or electronically. And, a decisive point for an opening timetable:

Failing notification within the period provided for in the first paragraph, the authorisation is deemed granted on the terms in which it was requested.

Silence therefore amounts to acceptance, not refusal. A landlord who makes the start of rent conditional on obtaining the signage authorisation must draft the clause so as to take account of this tacit outcome, failing which the tenant may argue the absence of an express decision in order to defer its opening.

Contents of the file and protected areas

Article R. 581-16, in the wording in force since 1 July 2026, states that the authorisation is granted having regard in particular to its integration into the environment. For any signage project, the file includes, in addition to the information and documents required by Article R. 581-7, a site plan locating the sign, a view of the building or place concerned with and without the sign, and a graphic document making it possible to assess the integration of the sign with the surrounding buildings and landscapes as well as its visual impact.

Where the project is planned for a location or place mentioned in Article R. 581-16-1, the file is reinforced: a cross-section of the façade that will carry the sign, a photograph placing the building incorporating the sign in its immediate surroundings, a photograph placing it in the wider landscape, and a description of the materials used and of the methods of carrying out the works. For an asset located in the vicinity of a historic monument or in a remarkable heritage site (site patrimonial remarquable), the real time needed to finalise the file, produce the graphic documents and consult the authorities beforehand in practice far exceeds the processing time. It is that time which must go into the marketing timetable, not the statutory time.

Securing the operability of the asset before the lease is signed

The due diligence reflex on a commercial asset traditionally covers title, planning, the environment, leases and service charges. Signage compliance is rarely addressed in its own right. It should be, because it conditions the tenant's ability to trade on the economic terms on which the rent is founded.

Four checks should be carried out beforehand, and their results feed directly into the negotiation of the commercial lease and of the signage permitted.

• The RLP zoning applicable to the plot, and the requirements specific to that zone as regards surface area, methods, illuminated boxes, roof signs and ground-mounted signs. The content of RLPs varies from one municipality to another: no extrapolation from the national regulation is reliable.
• The existence and content of the signage authorisations issued to the sitting tenants, and their conformity with the terms on which they were granted. A sign installed in departure from the authorisation is unlawful in the same way as a sign without authorisation.
• The date of entry into force of the RLP or of its latest revision, which sets the starting point of the period for bringing existing signs into compliance.
• The fit between the business that the prospective tenant intends to signal and the size of sign that can actually be authorised, in particular for fast-food, pharmacy, bank branch or car dealership signs, whose signage charters are often incompatible with a restrictive RLP.

The contractual translation is simple to formulate and rarely written: a condition precedent of obtaining the signage authorisation for the benefit of the tenant, coupled with a mandatory filing deadline and a duty of diligence; a duty of cooperation on the landlord (supply of documents relating to the building, access to the façade, permission to drill, agreement on materials) without transfer of the status of applicant, which the text reserves to the operator; and a clear provision on the fate of the lease in the event of a final refusal.

The contractual allocation of the burden of compliance

This is the point where the commercial lease and the policing of signage meet. For contracts entered into or renewed from 1 September 2014, Article L. 145-40-2 of the French Commercial Code requires that every lease contain a precise and exhaustive inventory of the categories of charges, taxes, duties and fees relating to that lease, indicating how they are apportioned between the landlord and the tenant. That inventory gives rise to an annual summary statement. On conclusion of the contract, and then every three years, the landlord provides each tenant with a forecast statement of the works planned over the following three years, together with a forecast budget, and a summary statement of the works carried out over the preceding three years, with their cost. The sharing of expenditure between landlord and tenant, item by item, is set out in our article on the allocation of commercial lease charges.

A campaign of removing and refitting signs imposed by a new RLP on a retail complex is intended to appear in those statements. Omission is not neutral: it weakens re-invoicing and fuels the tenant's challenge. The treatment of the local tax on outdoor advertising, whose legal basis was recently recodified, must likewise be expressly entered in the inventory; its exact regime must be checked against the text before any figure is stipulated.

Article R. 145-35 of the Commercial Code, applicable to contracts entered into or renewed from 5 November 2014, sets the limit of public policy. The following may not be charged to the tenant: expenditure relating to works intended to remedy obsolescence or to bring the let property or the building in which it is located into conformity with regulations, where they fall within the major repairs referred to in the preceding paragraph, that is to say those of Article 606 of the French Civil Code.

The wording must be read exactly. The bar applies only if the compliance works fall within the major repairs (grosses réparations) within the meaning of Article 606. It does not follow from this text that signage compliance, which most often concerns a fascia, a box sign or a totem, could never be charged to the tenant. But drafting is an exercise in precision: a blanket clause transferring all compliance works to the tenant without distinction is open to challenge where it extends to works affecting the structural fabric of the façade. Good practice is to isolate the cost of the sign and its fixing accessories, consistently with the maintenance obligation that Article R. 581-58 of the Environmental Code already places on the operator. On the distinction between major repairs and tenant's repairs, see our analysis of Article 606 of the Civil Code applied to the commercial lease.

The landlord moreover retains its own obligations. Article 1719 of the Civil Code requires it to deliver the thing let, to maintain it in a condition fit for the use for which it was let, and to ensure the tenant's peaceful enjoyment of it. A unit marketed as a visible location whose signage is refused opens a debate on the extent of that obligation of delivery. The exact effects of such a refusal, whether rent reduction, termination or compensation, are settled by no text and are a matter for the courts' assessment in light of the terms of the lease. All the more reason for the lease itself to deal with the scenario rather than leave it to the judge. The landlord's breaches of its obligation of delivery and the question of limitation periods for them are covered separately in our article on failure to deliver in a commercial lease.

The timetable for existing signs made non-compliant

Where an RLP enters into force and renders non-compliant signs that are already installed, Article L. 581-43 of the Environmental Code provides for a transition. Signs put in place before the entry into force of the measures adopted in application of, in particular, Articles L. 581-14 and L. 581-18, second and third paragraphs, and which do not comply with their requirements, may, provided they do not breach the earlier regulation, be maintained for a maximum period of six years from the entry into force of the aforementioned measures. The second paragraph applies the same maximum period of six years to signs subject to authorisation that do not comply with regulations that came into force after their installation.

Two clarifications avoid a common error of analysis. First, the reduced two-year period that a decree may provide for concerns only advertisements and pre-signs: it does not apply, by that route, to signs. Second, the two-year period in Article L. 581-43 covers two specific situations: that of devices put in place under the earlier special regulations mentioned in the last paragraph of Article L. 581-14-3, at the end of the period it provides for, and that of the advertisements and signs referred to in Article L. 581-14-4, that is, illuminated devices located inside display windows or bays, put in place before the entry into force of an RLP adopted in application of that text. A window screen installed before the RLP therefore enjoys a much shorter tolerance than the façade fascia.

Keeping a sign beyond the deadline is heavily penalised: Article L. 581-34, II, punishes with a fine of €7,500 the act of leaving in place an advertisement, sign or pre-sign beyond the compliance periods provided for in Article L. 581-43, as well as the act of obstructing the carrying out of works by the authority. For a retail portfolio, these deadlines must appear in the asset management schedule alongside renewal dates or triennial break dates.

Administrative policing: who actually bears the risk

The contractual allocation of the burden does not alter the municipality's designation of the person liable. Since 1 January 2024, pursuant to Article 17 of Law No. 2021-1104 of 22 August 2021, Article L. 581-3-1 of the Environmental Code provides that the powers relating to the policing of advertising are exercised by the mayor in the name of the municipality, and that those powers may be transferred to the president of the public inter-municipal cooperation body under the conditions laid down in Article L. 5211-9-2 of the General Local Authorities Code. The former allocation making the prefect the default authority where there is no RLP no longer applies.

The mechanism then moves quickly. As soon as an unlawful sign is found, the mayor issues an order (arrêté) requiring, within five days, either removal or compliance, together with, where appropriate, restoration of the premises (Art. L. 581-27 of the Environmental Code). That order is notified to the person who affixed, caused to be affixed or maintained after formal notice the unlawful sign; if that person is not known, it is notified to the person on whose behalf the sign was made.

On expiry of the five-day period running from the day the order is notified, the person to whom it was notified is liable to a daily penalty (astreinte) of €200 per day and per sign maintained, an amount revalued each year in line with changes in the cost of living (Art. L. 581-30 of the Environmental Code). The penalty is recovered for the benefit of the municipality in whose territory the facts were observed. The mayor may grant a remission or partial refund where the works ordered have been carried out and the person liable shows that it could meet the deadline imposed only because of circumstances beyond its control. On a retail complex with several non-compliant devices, the daily and per-unit nature of the penalty produces amounts that very quickly cease to be trivial.

Finally comes enforcement by the authority. Article L. 581-31 allows the mayor to have the works ordered by the order carried out by the authority if they have not been carried out within the period set. The costs are borne by the person to whom the order was notified, unless the enforcement of the provisions on the daily penalty has been suspended by the administrative judge sitting in summary proceedings (référé). The mayor must notify the private owner or occupier of the premises, at least eight days in advance, of the date on which the works will begin.

Two lessons for a landlord. First lesson: it is exposed as owner of the premises and, where relevant, as the person on whose behalf the sign was made, in particular where the operator has disappeared or the sign remains on a vacant unit. The texts do not create any statutory joint liability between landlord and tenant for the daily penalty; that does not, however, protect the owner, who may become the addressee of the order. Second lesson: the eight-day period preceding the enforcement works is the last useful window. Beyond that stage, the façade is dismantled by the municipality, at the expense of the addressee of the order, and the lease changes nothing. The response, if there is one, is a response in administrative summary proceedings, on a timetable counted in days.

To these penalties is added the criminal fine of €7,500 under Article L. 581-34, I, incurred in particular where a sign is affixed or maintained after formal notice without having obtained the prior authorisations, without having complied with the conditions laid down by those authorisations, or without having complied with the specific provisions laid down by the local advertising regulation.

End of lease: removal of the sign and return of the unit

Article R. 581-58 of the Environmental Code requires that the sign be made of durable materials and kept in a good state of cleanliness, maintenance and, where applicable, working order, by the person carrying on the business it signals. It adds that the sign is removed by the person who carried on the business signalled and the premises are restored within three months of the cessation of that business, except where it is of historic, artistic or picturesque interest.

The three-month period is short in relation to end-of-lease practice, and it does not necessarily coincide with the effective date of the notice to terminate or with the return of the keys. The return clause must therefore expressly cover removal of the sign, restoration of the façade supports and drill holes, reinstatement of the electrical supplies, and production of proof of removal. For an institutional landlord, the practical interest is twofold: to avoid being left as owner of a vacant unit bearing a non-compliant sign in a zone where the RLP requires it to look after the external appearance of the unit, and to preserve the ability to re-let without taking on the cost of signage compliance that it did not cause.

Conclusion

Signage compliance is not a matter of housekeeping: it is a component of the operability of the asset, on a par with energy performance or the regularity of planning permissions. A restrictive RLP does not show up in a rent roll, does not appear in the title deed and does not appear either in a standard technical audit. It comes to light when the tenant files its application, or worse, when the mayor notifies an order on the basis of Article L. 581-27 and the daily penalty of €200 per sign begins to run five days later.

Our position is that the subject must be dealt with ahead of the acquisition decision and not at the management stage. Before any signature, have a signage compliance note prepared for each plot: applicable RLP zoning, date of entry into force of the regulation and starting point of the six-year period under Article L. 581-43, existing authorisations and discrepancies found, size of sign that can actually be authorised in light of the signage charter of the prospective tenant. Then carry it into the lease: condition precedent of authorisation, duty of cooperation on the landlord without transfer of the status of applicant reserved to the operator by Article R. 581-9, express allocation of the burden of compliance drafted with the limit of Article R. 145-35 in mind, and a removal clause tied to the three-month period of Article R. 581-58. An asset whose commercial visibility is legally secure is not negotiated at the same price as an asset whose signage is merely tolerated.

Frequently asked questions

Is every sign subject to authorisation in France? No. Article L. 581-18, paragraph 4, of the Environmental Code makes the installation of a sign subject to authorisation on the buildings and in the places mentioned in Articles L. 581-4 and L. 581-8, as well as within the framework of a local advertising regulation. Where there is no RLP and outside those places, the installation is not subject to that authorisation regime, but it remains bound to comply with the requirements of the national regulation, in particular Articles R. 581-59, R. 581-60, R. 581-63 and R. 581-64. Since 1 January 2024, signs using a laser beam are subject to the mayor's authorisation.

Can the landlord file the signage authorisation application itself? No. Since 1 July 2026, Article R. 581-9 of the Environmental Code, in the wording resulting from Decree No. 2025-1354 of 26 December 2025, provides that the application is made by the person or undertaking carrying on the business signalled. The applicant is therefore the tenant operating the business. The lease can and must organise the landlord's cooperation, access to the façade, supply of documents, agreement on materials, but it cannot transfer the status of applicant.

What happens if the town hall does not respond to the signage authorisation application? Article R. 581-13 of the Environmental Code, in force since 1 July 2026, requires the competent authority to rule within two months of receipt at the town hall of a complete file, the file being deemed complete if the list of missing documents has not been notified within one month of its receipt. Failing notification within the two-month period, the authorisation is deemed granted on the terms in which it was requested. Silence therefore amounts to tacit acceptance, not refusal.

How long can an existing sign be kept after a new RLP enters into force? The general period is six years. Article L. 581-43 of the Environmental Code allows signs that do not comply with the measures adopted in application of, in particular, Articles L. 581-14 and L. 581-18 to be maintained for a maximum period of six years from the entry into force of those measures, provided they do not breach the earlier regulation. A period of two years applies, however, to illuminated signs located inside display windows or bays referred to in Article L. 581-14-4 where they breach the RLP adopted in application of that text.

Can the cost of bringing the sign into compliance be charged to the tenant? Article R. 145-35 of the Commercial Code, applicable to leases entered into or renewed since 5 November 2014, prohibits charging to the tenant the cost of works to bring the let property or the building into conformity with regulations, but only where those works fall within the major repairs of Article 606 of the Civil Code. The clause must therefore isolate precisely what relates to the sign and its accessories. It must also fit within the precise and exhaustive inventory of charges required by Article L. 145-40-2 of the Commercial Code.

Who pays the daily penalty for an unlawful sign, the landlord or the operator? The daily penalty of €200 per day and per sign maintained under Article L. 581-30 of the Environmental Code falls on the person to whom the order under Article L. 581-27 was notified, that is, the person who affixed, caused to be affixed or maintained the sign after formal notice, or, if that person is not known, the person on whose behalf the sign was made. The texts do not create any statutory joint liability between landlord and tenant. The owner nonetheless remains exposed, in particular on a vacant unit, and must be informed at least eight days in advance of the date on which enforcement works begin under Article L. 581-31.

Can the legality of an RLP still be challenged once the compliance order has been notified? Not for defects of form or procedure, beyond a certain time limit. Article L. 581-14-1 of the Environmental Code prohibits raising by way of exception illegality on grounds of defective form or procedure committed when drawing up, revising or approving an RLP once a period of six months has elapsed from its entry into force. This time bar does not apply where the defect consists of a substantial disregard of, or a manifest breach of, the rules governing the public inquiry. A challenge must therefore be brought within the window opened by publication of the regulation, and not at the penalty stage.
