Do you need a permit for a sign in Costa Rica?

Article 29 of the national Construction Law is the hook. To place or fix an announcement, sign, lettering or notice you must apply for a licence from the Municipality. The application is made by the owner of the structure the sign is fixed to, with the agreement of the owner of the property where that structure stands. Where frames or structures are used, the Municipality requires a perito responsable — a professional answering for the construction. And a dimensioned sketch, a croquis acotado, must be submitted.

Article 30 prohibits signs that cross a public road, and signs fixed to utility poles or to the trees of parks and gardens. Article 31 gives the municipality authority over how much of a façade a sign may occupy, and lets it refuse. Article 32 adds eight absolute prohibitions — public buildings, schools and temples, national monuments, lamp posts and kiosks, private houses and fences, someone else's board, and anywhere the sign would obstruct traffic visibility.

Article 33, as reformed by Ley 9482 in 2017, sets the penalty: a fine of 5% to 10% of one salario base, plus dismantling at the owner's cost. With the 2026 salario base set at ¢462,200, that arithmetic gives roughly ¢23,110 to ¢46,220. The ¢10 to ¢100 figure still circulating in older copies of the law was repealed and should be ignored.

Three of the four Guanacaste cantons we work in most have no sign regulation at all. In that gap the INVU Reglamento de Construcciones applies. Its article 148 sets the defaults: exterior advertising must not block accessibility or free passage; in residential zones a sign may be at most 2.00 m² and must sit parallel to the street; in commercial and industrial zones it may be perpendicular, provided it does not project over the sidewalk; the lower edge must be at least 2.50 m above the sidewalk; and a sign must stand at least 1.00 m from street nameplates.

Two neighbouring articles matter in practice. Article 149 sends declared heritage areas to their own regime — the centre of Liberia is one. Article 115 sets the clearances a sign must keep from medium- and low-voltage lines.

If your sign is anywhere near a national road, the municipality is not the only authority. The Reglamento de los Derechos de Vía y Publicidad Exterior — Decreto Ejecutivo No. 29253-MOPT, La Gaceta No. 25 of 5 February 2001 — makes MOPT the sole authority for signs in and near national rights-of-way, and its article 10 requires MOPT authorization for any sign inside a band 200 metres wide on each side of the centre line. That band is far wider than most business owners expect, and it is the single most common reason a sign that looked like one municipal errand turns into two applications.

Article 49 sets the maxima. Commercial and industrial premises: a freestanding sign of up to 1.5 m² per linear metre of frontage, no more than 16 m tall; wall and awning signs up to 30% of the façade; an under-marquee sign up to 0.75 m² with 2.40 m of clearance. Residential premises: 0.50 m² per linear metre, total height up to 8 m.

Article 47 exempts a short list: temples, directional signs up to 1 m², temporary holiday decorations, plaques on the inside of windows and doors, for-sale or for-rent signs of up to 1 m² on the property itself, and signs inside a shopping centre facing internal corridors or parking. Article 48 sets what you file — a scaled sketch showing the support and anchoring, or a photo-montage with measurements; and for a structure over 10 m² per face, or a complex one, stamped structural drawings with a memoria de cálculo signed by a responsible engineer.

On timing, the Ley de Tránsito No. 9078, Transitorio XIII, gives MOPT 30 días naturales to decide.

Three separate triggers, and any one of them is enough. Structure: Ley 833 article 29 requires a perito responsable wherever a frame or supporting structure is used, with no size floor. Size: Decreto 29253-MOPT article 48 requires stamped structural drawings and calculations above 10 m² per face. Cost: under article 83 bis of Ley 833, works below ten salarios base may skip the responsible professional — but the municipal licence is still required, and structural or electrical work is never treated as a minor work.

Signs are an explicit project type in the CFIA's APC registration system, so the professional's contract is registered there and the sealed plans are valid for one year.

This is the part most articles on the subject get wrong, by filling the gaps with numbers nobody published. Here is what we could and could not verify.

Santa Cruz, which includes Tamarindo, has no sign regulation. Its municipal licensing regulation and its construction-control regulation never mention rótulos, and there is no sign form among the municipal forms published online. What the urban development office asks for in practice is not published anywhere. The 30 días naturales it does publish belong to the licencia comercial, not to a sign.

Liberia charges for signs and publishes no rule. Rótulos is one of its patente categories, and the municipality also lists a tasa especial de publicidad exterior — but neither the tariff, nor the legal basis, nor a document list is published. Applications go to the patentes unit by e-mail, and the municipality states that under the Código Municipal it answers within 30 business days on the status of a requested permit.

Nicoya adopted a new law in 2026. Ley No. 10934 of 12 May 2026 replaced the canton's old tariff law, and its article 24 requires a sign licence and sets an annual charge per square metre: 2.5% of the salario base mínimo for metal signs, 5% for illuminated signs and 3.5% for non-illuminated ones, with anything under 1 m² charged as though it were 1 m². The law gives the municipality six months to issue the implementing reglamento. We could not find that reglamento, and we could not confirm the Gaceta publication date — so treat those percentages as the text of the law rather than as a quoted counter tariff.

Carrillo publishes the only real sign regulation of the four, and it applies only inside the maritime-terrestrial zone. Its Reglamento de Instalación de Publicidad Exterior grants the licence to the concession holder, for one year at a time, renewable after inspection. It caps a sign at 1.00 m², requires at least 2.50 m of clearance above the sidewalk and plans drawn by a CFIA-registered professional, and in turtle-nesting zones forbids illuminated signage facing the sea and limits illuminated signs to 2 m in height. The annual canon runs from 4% of the minimum wage for a non-illuminated wall sign to 20% for any illuminated one — but a sign promoting a business that holds a municipal patente is exempt from the canon. Outside the maritime zone, Carrillo publishes no sign rule either.

So: no municipality in Guanacaste publishes a processing time for a sign permit, only two publish any tariff at all, and only one publishes a maximum size. We would rather tell you that than invent a number.

Ley 6043 and its regulations never mention signs — we checked, and that is a verified negative rather than an omission. A sign is caught anyway, because it is an installation: article 12 prohibits installations in the maritime-terrestrial zone without authorization and article 13 provides for demolition, while the first 50 metres, the zona pública, cannot be occupied at all. Building in the zone requires a registered concession, changes need the consent of both the municipality and the ICT, and the plans must carry the CFIA seal. On the beach, a sign is a concession question before it is a signage question.

Permits are part of what we do rather than something handed back to you at the end of the quote. We know the local requirements and our attorney handles the filing. It carries a separate cost, stated upfront in the quote — never folded silently into the price of the sign, and never added afterwards. The short version of this answer sits in our frequently asked questions.

Two things follow. Tell us early: a permit that starts when the sign is already fabricated is a permit that delays your opening, while one that starts alongside the design usually does not. And permit requirements shape the design rather than the other way round — if what you want will not be approved at that size, in that position or with that level of illumination, the time to find out is at the sketch stage, not after the sign has been built and the lift is booked.

Ley 833 names two documents in every case: the croquis acotado, and the written consent of the owner of the property where the structure stands. What each municipality adds to those we confirm with that municipality before we file, because a wrong list published here would be worse for you than no list at all.
