What the law requires: notice that works are starting
The rule is the Ley Orgánica de Ordenación Urbanística (LOOU, the urban planning law), Gaceta Oficial No. 33.868 of December 16, 1987. Its article 84 does not speak of a "permiso" (permit): it says that to start building "bastará que el propietario o su representante se dirija por escrito al respectivo municipio a fin de notificar su intención de comenzar la obra" (it will suffice for the owner or their representative to write to the relevant municipality to give notice of their intention to begin the works).
Along with it you hand in:
The alcaldía (city hall) must give you, on the spot, a dated, signed and stamped receipt. Keep it as proof.
The same article treats as the start of construction any activity that changes the existing physical environment, "tales como la deforestación, movimiento de tierra, demolición, construcción y refacción" (such as deforestation, earthmoving, demolition, construction and renovation). Adding a floor or extending a house falls within that.
Article 80 also requires a resident professional, from which the municipality may exempt a single-story single-family home built by its owner to live in. Before giving notice, you may request in writing a preliminary consultation on the variables for your plot (art. 81).
Only for urbanizaciones (housing developments) does the law expressly prohibit starting without the article 85 certificate (art. 84). In practice, alcaldías such as Sucre's handle this as an application with forms and fees, and speak of authorizing the start of works through a certificate. Ask at yours before you start.
The variables urbanas fundamentales and the deadlines
Article 85 gives the alcaldía 30 calendar days, for buildings, "para constatar únicamente" (solely to verify) that the project complies with the variables urbanas fundamentales (core zoning rules). Once verified, it issues the corresponding certificate (in Sucre, the constancia de cumplimiento de variables urbanas fundamentales (zoning compliance certificate)).
For a building, article 87 lists those variables: the use set by the zoning, front setback and access, gross population density, site coverage and building percentages, side and rear setbacks, height, restrictions for safety or environmental protection and any other that the plan imposes on the lot. In an extension, check above all the height, the setbacks and the building percentage.
| Step | Legal deadline | LOOU article |
|---|---|---|
| Reply to the preliminary consultation (buildings) | 15 business days | 82 |
| Verification of urban variables (buildings) | 30 calendar days | 85 |
| New review after correcting the project | 15 calendar days | 88 |
| Acknowledgment of receipt when the works are finished | 10 business days | 95 |
If the project does not comply, the alcaldía gives notice by a reasoned official letter that also orders the works to be halted if they have already begun (art. 88).
On completion, the responsible professional and the owner file a certificate that the works comply, with the final plans. The acknowledgment of receipt "será suficiente a los fines de la habitabilidad de la obra" (will suffice for the purposes of the building's occupancy) (art. 95).
The Ley de Promoción y Protección de la Construcción de Viviendas (Housing Construction Promotion and Protection Law; Gaceta Oficial No. 7.071 Extraordinario, August 25, 2026) sets other deadlines, such as 10 business days for the urban variables (art. 9), but it governs builders and developers of housing projects for sale or pre-sale (arts. 1, 8, 9 and 12 to 15) and does not mention the owner who extends their house. On the permiso de habitabilidad (occupancy permit) for those projects (art. 33), see occupancy permit.
What happens if you build without complying
Article 109 distinguishes two cases:
Article 102 allows the asociación de vecinos (neighborhood association) or any person with a legitimate, personal and direct interest to ask a judge to halt illegal construction. Under article 117 (parágrafo único, sole paragraph), actions against infractions are time-barred five years from the date of the infraction, unless actions by the planning authority interrupt the limitation period.
In a building: what the condominium decides
In an apartment, notice to the alcaldía is not enough. The Ley de Propiedad Horizontal (condominium law; Gaceta Oficial No. 3.241 Extraordinario, August 18, 1983) sets its own limits:
Any owner may challenge before a judge a majority decision that violates the law or the documento de condominio (condominium deed), or that is an abuse of rights, within 30 days after the assembly or after being notified of the decision (art. 25).
The law does not mention balconies or use the word fachada (facade). Whether closing in a balcony fits within article 4, needs the 75% of article 9 or the unanimity of article 10 depends on the works and on your documento de condominio. Review that document and consult a lawyer before hiring anyone. On the junta de condominio (condominium board) and the assembly, see how a condominium works.
Where to apply: the example of Sucre (Miranda)
The competent office is your alcaldía's Ingeniería Municipal (municipal engineering office) or urban control office. The only official page with detailed procedures we found is that of Sucre's Dirección de Ingeniería y Planeamiento Urbano Local (local engineering and urban planning department) (Petare). It offers, among others:
The application starts online; the list of required documents does not appear on the public page. According to the page, which is undated, these procedures cost 10 UT (tax units) of the Gobernación de Miranda (Miranda state government) in timbres fiscales (revenue stamps) plus a fee based on zoning, use and square meters. The page does not say what that UT is worth; do not confuse it with the SENIAT (national tax agency) one, which is only used for national taxes. Confirm amounts and required documents at the office.
Buying or selling a house with extensions without a permit
If an extension was never notified, there is no file at Ingeniería Municipal and no completion certificate. The property document describes what was declared when it was registered, not the square meters added later, and the ficha catastral (cadastral record) may still show the previous area. Sucre's Catastro (cadastral office), for example, has a "cambio de terreno a construcción" (change from land to building) procedure if the cédula catastral (cadastral certificate) records only land.
For the buyer:
The LOOU also protects the buyer: whoever sells, after completion, a building they built or had built is liable under the terms of article 1.637 of the Código Civil (Civil Code) (art. 100), which covers total or partial collapse, or its evident danger, due to a construction defect or a defect in the ground in the ten years after completion; the claim must be filed within two years. A clause that excludes or limits that liability is not valid (art. 101). For other hidden defects, see hidden defects and the seller's warranty.
