You’ve found your Andalusian dream: a whitewashed village house with a lemon tree out back and a view that keeps you on the terrace too long. The seller swears it’s “all in order,” the agent calls it “regularisable,” and the notary date is set. Then a detail lands on your desk: there’s no building licence on record. The lights run off a creative connection, the septic “works… most of the time,” and the town hall wants to “review the situation.”
Take a breath. In Andalusia, this is common—not fatal. The question isn’t “legalise overnight,” it’s how to manage an irregular, time-barred home so you can live safely and connect utilities without digging a deeper hole.
This guide walks you through exactly that path: how AFO works in 2025 under Law 7/2021 (LISTA) and Decree 550/2022, what it allows (minimal safety/health works and conditioned utilities), what it doesn’t (extensions, new rights), and how grouped areas are handled via Special Plans. If you’re still pre-purchase, you’ll see how to price risk; if you already own it, you’ll see the steps to get out of limbo—cleanly and fast.
Executive summary
- Scope: any municipality in Andalusia.
- Legal framework: Law 7/2021 (LISTA) and Decree 550/2022.
- Goal: if the infringement is time-barred and the dwelling is outside protected/risk areas, apply for AFO to enable minimal safety/health works and conditioned access to water, sanitation, electricity.
- Limits: AFO does not legalise or allow extensions.
- Grouped areas: a Special Plan may apply; each home still needs its own AFO.
- Who can help: Costaluz Lawyers handle the process across all Andalusian municipalities.
Q&A guide
Confirm two things: 1) there’s no active enforcement file and the infringement is time-barred; 2) the property is not on protected land or in a risk zone. If both check out, prepare the AFO application.
An administrative recognition for irregular but time-barred buildings. It allows minimal safety/health works and conditioned utility connections. It does not legalise the building or grant new development rights.
A technical report proving completion date and current condition; safety/health measures (structure, fire, ventilation, sanitation); a water and sanitation solution (e.g., septic or connection plan); an electricity compliance route; plans and photos; municipal fees.
Only what’s strictly necessary for safety and salubrity, and to meet utility connection conditions. No extensions, extra floors, or “improvement” works that increase surface or volume.
Yes, conditionally, once you implement the technical measures required by the Town Hall and the utility provider.
Your council may process a Special Plan for Environmental and Territorial Adaptation. It sets infrastructure, environmental criteria, and owner contributions. It does not regularise by itself—each home still needs its AFO.
Do enhanced due diligence: an urban status certificate from the Town Hall; a nota simple (Land Registry); evidence of age/completion (Cadastre, bills, aerials); checks for coastal/environmental protections and risk. Use findings to renegotiate or walk away.
A: Common reasons: no prescription, active enforcement, protected/risk land, or failure to meet minimum technical safety/sanitation conditions.
A: Municipal fees, technical fees for the report, and any works required (septic, connections, meter cabinet). Timing varies by municipality and by how complete your file is.
A: Only as background. For action in 2025, rely on the LISTA (Law 7/2021) and its General Regulation (Decree 550/2022).
Owner checklist
- Prescription confirmed; no live enforcement.
- No protected designations or risk constraints blocking AFO.
- Technical report + safety/health + water/sanitation + electricity plan + fees.
- After AFO, execute only minimal works and connect services as conditioned.
- If in a grouped area, follow the Special Plan and budget for infrastructure contributions.
Municipal pointers (any Andalusian council)
- Maintain ordinances clarifying “finished building” and the scope of minimal post-AFO works.
- If a Special Plan is needed, use clear mapping/fiches and a solid strategic environmental assessment.
- Communicate the difference between AFO (managing existing stock) and planning-led regularisation.
Bottom line
An AFO is not a back-door legalisation. It’s a management status that brings legal certainty for basic habitability and utilities—if the case meets prescription and no-protection tests. Budget for technical fixes; don’t plan extensions.

An unlicensed extension is one kind of pre-purchase problem to check for — if the issue instead turns out to be occupation by someone with no title at all, see what a Spanish property owner can do about squatters.
