Before you purchase a lot with the intent of building on it, you should conduct some preliminary studies on the property to ensure that there won't be a problem obtaining a building permit. First, determine if the lot has basic services such as water, electricity, telephone, and drainage. Second, make sure there are no restrictions placed on the lot that could result in the denial of a construction permit. It will not be enough to check the Public Registry. You should also check the Ministry of Public Works (Ministerio de Obras Públicas y Transporte) for future road construction projects; the Ministry of Health (Ministerio de Salud); the National Institute of Housing and Urban Development (Instituto Nacional de Vivienda y Urbanismo) and the municipality where the property is located (municipalidad). And finally, be aware of any environmental regulation that may affect your construction project, such as national wildlife refuges, national parks and other areas deemed protected by the forestry laws.

Requests for construction permits are filed with the Permit Reception Office (Oficina Receptora de Permisos de Construcción), which is a centralized office that houses government representatives from MOPT (Ministerio de Obras Públicas y Transportes-roads), INVU (Instituto Nacional de Vivienda y Urbanismo-housing), ICE (Instituto Costaricense de Electricidad-telephone), AYA (Instituto Costaricense de Acueductos y Alcantarillados-water), SNE (Servicio Nacional de Electricidad-electricity), CFIA (Colegio Federado de Ingenieros y Arquitectos), and the Ministry of Health (Ministerio de Salud).

For a single family home that measures more than 70 m2 (735.2 ft.2), the applicant must provide the following documentation: four copies of the construction plans, four copies of the property cadastre plot plan (Plano catastrado), four copies of the permit checklist (hoja de comisión), two copies of your property deed (escritura), one copy of the consulting contract with your architect/engineer (contrato de consultoria), an approval from the water company (AYA) regarding availability of water, and one copy of your electrical design plan approved by SNE. Condominium projects, commercial construction, and urbanization projects all carry additional requirements for obtaining construction permits.

In addition to these requirements, you will need to request a building permit from the municipality in which the property is located. By law it is the municipality that is delegated the responsibility to ensure that all constructions comply with building regulations (Article 1, Construction Law).You can, therefore, expect periodic visits to your construction site by the municipal building inspector, who must certify that the construction is proceeding according to code. Whether you purchase an existing property or decide to build you dream home, be well informed about the procedures involved so that you ensure your investment will be a profitable one.
