Running a renovation from outside Spain

Terms used

• Poder notarial — The poder notarial is a notarised power of attorney that lets another person act and sign for you in Spain.
• NIE — The NIE is the identification number Spain gives to foreigners, used for property and tax matters.
• Declaraciones responsables — Declaraciones responsables are sworn statements to the town hall that let some minor works start without waiting for a full licence.
• Aparejador — The aparejador is the technical architect who controls materials, quality and costs on site and certifies each stage of the works.
• Contrato de obra — The contrato de obra is the written building contract with the builder, setting scope, price, timetable and penalties.
• Lista de remates — The lista de remates is the snag list of unfinished or faulty items the builder must fix before final payment.

Key rules

• Power of attorney: Keep the power limited and list each task, so your agent can act without having wider authority than you want.
• Staged payments: Pay only against stages certified by the technical architect or architect, not up front.
• Written changes: Approve every change or extra in writing before work on it starts.
• Defect protection: The law protects you for 1 year on finishes, 3 years on habitability and 10 years on structure.

The short version

You can run a renovation from abroad if three things are in place: someone with legal authority to act for you, professionals who check the work on site, and a contract that ties payments to progress. Everything else is routine follow-up.

Give someone legal authority: the power of attorney

A power of attorney (poder notarial) lets a person you trust sign and apply for things in your name. Without it, you would have to fly in for every licence or contract.

You can sign it in three ways:

• Before any Spanish notary during a visit.
• At a Spanish consulate abroad, where the consul acts as notary.
• Before a local notary in the country where you live. If that country is in the Hague Convention, the document needs an apostille. Otherwise it needs consular legalisation. If it is not in Spanish, add a sworn translation.

You need your passport and your NIE. Your agent needs an NIE for tax matters and, in practice, ID for dealing with offices.

Keep the wording specific. List the tasks: applying for planning licences or declaraciones responsables, signing contracts with the builder and architects, paying taxes and fees, dealing with utilities and the community, and representing you before the town hall. A broad power is possible, but a limited one is safer. If you ever sell or mortgage the property, the power must say so expressly. The notary's fee is modest and set by a tariff. You can revoke the power at any time before another notary.

Notaries and receiving offices may ask for particular wording or recent dates, so ask them before you sign.

Hire the people who watch the site for you

The dirección facultativa is the professional team that directs the works. For you, it acts as your eyes on site.

• The architect designs and signs the project and checks that the works follow it.
• The aparejador (technical architect) controls materials, quality and costs, certifies each stage and signs the completion certificate.
• A health and safety coordinator is also required.

They check the builder's invoices and certifications, handle licences and the final certificate, and report to you on progress.

Fees are usually a percentage of the cost of the works, often split between design and site direction. The percentage falls as the project grows. Small jobs often have a fixed fee for a defined scope. Professional associations no longer publish binding scales, so get several quotes and compare them with what local associations (colegios) suggest.

Control the builder and the money

Sign a written contract (contrato de obra) with a fixed scope, a detailed budget (presupuesto), a timetable and penalties for delay.

Pay against stages that the aparejador or architect has certified, never everything up front. A typical structure is a small deposit of about 10 to 20% of the price, then payments on certified stages. Holding back around 5% until the snag list is cleared is common. These are usual practice, not legal rules, so negotiate them in the contract.

Add these habits:

• Ask for regular photo or video reports and a weekly call or report.
• Arrange visits, by you or your agent, at key stages: foundations, structure, and installations before walls are closed.
• Approve every change or extra in writing before work on it starts.
• Draw up a snag list (lista de remates) before the final payment.
• Check the builder's insurance, registration and social-security status before you sign.

After the works

Collect the completion certificate, the guarantees and the invoices with VAT. The law gives you protection against defects: 1 year for finishes, 3 years for habitability problems and 10 years for structure.

The checklist, documents list and FAQ below cover these steps in more detail.

Documents you need

• Power of attorney (poder notarial) signed before a Spanish notary, a Spanish consulate, or a local notary in your country.

• Apostille on the power of attorney if it was signed before a local notary in a Hague Convention country; other countries need consular legalisation instead.

• Sworn translation into Spanish of the power of attorney, if it is not written in Spanish.

• Your passport and your NIE (Spanish foreigner number), which you need to grant the power.

• The agent's NIE and ID, needed for tax matters and in practice for dealing with offices.

• Written building contract (contrato de obra) with a fixed scope, detailed budget, timetable and penalties for delay.

• At the end of the works: certificate of completion, guarantees and invoices with VAT.

Checklist

• Sign a limited power of attorney that names each task: licences, builder and architect contracts, taxes and fees, utilities, community and the town hall.

• Hire an architect and a technical architect (aparejador) to direct the works, and confirm a health and safety coordinator is appointed.

• Compare several fee quotes from architects and technical architects, and agree whether the fee is a percentage or a fixed amount.

• Sign a written contract with the builder that sets scope, budget, timetable and penalties for delay.

• Link payments to stages certified by the technical architect or architect, with a small deposit and about 5% held back until the snag list is cleared.

Frequently asked questions

Can I sign the power of attorney without travelling to Spain?

Yes, you can sign it at a Spanish consulate in your country, where the consul acts as notary, or before a local notary there.

How are project manager fees usually charged?

Fees are usually a percentage of the works' cost, often split between design and site direction, and the percentage falls as the project grows. Small jobs often have a fixed fee for a defined scope, and hourly rates are sometimes used for consulting. Compare several quotes.

How long am I protected against defects after the works?

Spanish law gives a legal guarantee of 1 year for finishes, 3 years for habitability and 10 years for structure. Keep the completion certificate, guarantees and invoices to back up any claim.
