Building a Custom Villa: The ‘Licencia de Obra Mayor’ Timeline in Costa Adeje

For high-net-worth investors, acquiring an existing luxury property in Costa Adeje often requires compromising on architectural layout or settling for dated interior infrastructure. To achieve exact specifications, many buyers opt to acquire a prime plot of urban land (parcela urbana) in areas like Golf Costa Adeje or Abama and construct a bespoke luxury villa from the ground up.

While the financial yields and personal satisfaction of a custom build are substantial, the structural bottleneck in Tenerife is rarely construction capability; it is the local administrative bureaucracy.

Initiating a major construction project requires securing a Licencia de Obra Mayor (Major Building License) from the Adeje Town Hall (Ayuntamiento). Understanding the technical phases of this application and the realistic timelines involved is crucial for accurate project management.

The Architectural Foundation: Proyecto Básico

The licensing process begins long before earth is moved. Once a plot is acquired, the investor’s appointed architect (Arquitecto) must draft the Proyecto Básico (Basic Project).

This is a comprehensive architectural proposal detailing the external footprint, elevations, floor plans, and overall volume of the proposed villa. The primary function of the Basic Project is to demonstrate to the Town Hall’s urban planning department (Urbanismo) that the design strictly adheres to the local zoning regulations. This includes respecting maximum buildable volume (edificabilidad), boundary setbacks (retranqueos), and maximum height restrictions.

The Proyecto Básico must be endorsed by the official College of Architects (Colegio de Arquitectos) in Tenerife before it is formally submitted to the Adeje Town Hall to initiate the license application.

The Town Hall Timeline and Delays

Once the Basic Project is submitted, it enters the municipal review process. Under Spanish administrative law, town halls are theoretically required to respond to building license applications within three months. In the highly active municipality of Adeje, this statutory timeline is rarely met.

Currently, due to the volume of luxury developments and municipal staffing constraints, investors should anticipate a waiting period of 12 to 18 months from the date of submission to the formal issuance of the Licencia de Obra Mayor.

During this period, the municipal architect may issue formal requests for modifications (requerimientos) if the design conflicts with local bylaws. The investor’s architect must revise and resubmit the plans, temporarily pausing the administrative clock until the corrections are approved.

The Proyecto de Ejecución

While waiting for the Town Hall to process the Basic Project, the investor’s architectural team will draft the Proyecto de Ejecución (Execution Project).

This is a highly detailed, technical blueprint required by the construction company to physically build the villa. It dictates the structural engineering, plumbing schematics, electrical grids, HVAC integration, and the exact material specifications (memoria de calidades).

Construction cannot legally commence until both the Licencia de Obra Mayor is granted based on the Basic Project,and the Execution Project has been formally registered with the Town Hall.

The Start of Works (Acta de Replanteo)

Once the license is in hand, the administrative phase concludes with the Acta de Replanteo. This is a formal, on-site meeting between the architect, the technical architect (Aparejador), the building contractor, and the property owner.They verify the physical boundaries of the plot against the approved plans and formally sign the document authorizing the physical commencement of earthworks.

From this point, the construction of a modern luxury villa in Costa Adeje typically requires a further 15 to 20 months of active building time, depending on the complexity of the foundations and retaining walls.

Aligning your capital deployment schedule with the administrative timelines of the Adeje Town Hall is essential for maintaining accurate project budgets during a custom villa build.
