This really needs to be done in Spanish, as it is quite complex and involves several agencies in Costa Rica for final approval.

I will explain it in English and keep it very general so you can understand the overall idea more easily.

Background on Construction Permits in Costa Rica

Until a few years ago, Costa Rica had a very practical law: any construction under 30 square meters only required “Croquis.”
These were basic layouts and designs that almost anyone could prepare. No architect, no engineer, and no additional signatures were required outside the Municipality. It was simple and fast.

However, the Colegio de Arquitectos later lobbied and complained that they were not receiving their share of commissions on small projects. Traditionally, architects receive 10% of the project value, although in practice most charge 4–8%, depending on the architect.

For example, on a home valued at $200,000, a 10% fee would be $20,000.

As a result, the permitting process became more complex.

Estudio de Perspectiva

The Estudio de Perspectiva is divided into two categories:

  • Servicio Profesional (what you pay the architect)
  • Pagos Institucionales (what you pay institutions and government entities)

Servicio Profesional

1. Estudios Preliminares y Anteproyecto
This is the initial project pre-study.
Fee: 1% of the total project value
Typically, 50% is paid upfront and the balance upon completion.

2. Planos Constructivos y Especificaciones Técnicas
Fee: 4% of the project value
This covers the creation of the official construction plans and technical designs. This is usually the most expensive and most scrutinized part of the process.

3. Inspección
This is when the architect is supposed to visit the site, document progress, and record it in their legal logbook.
They are generally expected to visit three times.
In my experience, they often visit once—or not at all—yet still charge for it.
The percentage for this service was not listed in my quote and is negotiable.

4. Dirección Técnica
Fee: 5% of the project value
This is when the architect assumes full legal responsibility for the construction. They maintain the official construction log and document progress and completion.

Pagos Institucionales

5. Visado del Colegio de Ingenieros y Arquitectos, incluida la Bitácora de Obra
Fee: 0.265% of the project value
This covers plan approval and registration with the Municipality.

6. Administración APC + Bitácora
Flat fee: $47
This covers online registration and use of the official Bitácora (construction log) system.

7. Formularios de SETENA y Estudio de Impacto Ambiental
This applies only to large projects, multiple dwellings, or developments with environmental impact.

8. Póliza de Riesgos Profesionales del INS (monto incluido en el costo de la obra)
Municipal processing fee: 1.71% of project value
Worker insurance cost: 0.068% of worker wages
Example: If you pay two workers ₡100,000 per week, insurance for three months may be around ₡168,000.

9. Impuesto Municipal por Construcción
Tax: 1% of construction value
If construction begins without permits, the tax increases to 2%.

10. Ingeniero Eléctrico
Flat fee: ₡100,000
Covers electrical layout and cable specifications.

Shipping Container Homes & Permits (General)

Permits for shipping container homes vary greatly depending on country, province, canton, and municipality.

There is no universal explanation—building regulations vary widely regardless of construction type.

Container homes are permitted differently than traditional homes, but they are still complicated.

If you want to avoid permits and complex inspections, the structure must closely resemble an RV (Recreational Vehicle)—essentially a home on wheels.

I have met container-home contractors in Austin, Texas who intentionally install wheels on 20-ft ISO containers to qualify under RV or food-truck regulations.

These “wheeled” structures often fall into categories similar to RVs or food trucks, which in many cases require fewer permits.

Food trucks, however, still require health and business permits.

Specifically for Costa Rica

Electricity:
Contact ICE.
Poles and materials usually cost under $200.

Water:
Contact AyA.
They require proof of an existing structure.
Water hookup is inexpensive—often close to free.

Septic:
Apply at the Municipality (about $30, a few days).
Hire a local contractor to excavate and install the system.
Costs depend on system type and quality.
Our system used a backhoe and a large concrete cylinder.

For now, that is all the information I have.
