My neighbour is building without a permit or breaking the rules — who checks?
Building rules are enforced by the building authority — Câmara Municipal — urbanismo / fiscalização (anmp.pt): they check whether a permit exists (permits are public, you can ask to see it), inspect, and can stop works or order demolition. Boundary distances, height, windows facing your garden — those are in the permit or the zoning plan. If a permit was granted and you disagree, you can object to the permit within a short deadline (often 4–6 weeks from publication) at Tribunal Administrativo e Fiscal (citius.mj.pt); afterwards it is Segurança Social — apoio judiciário / Ordem dos Advogados (seg-social.pt). Works that damage your property are a civil matter in parallel.
🗣️ What to say
"At [address] construction works are under way since [date]: [what]. I ask whether a permit was granted and, if not, for an inspection and enforcement. [If a permit exists: I object to the permit because …] Photos attached."
🪜 Step by step
- Check for a permitAsk Câmara Municipal — urbanismo / fiscalização or the online register; permits are public. Look at the plans — what was approved.
- No permit: enforcementReport with photos; the authority inspects and can order a stop.
- Permit exists: object on timeThe deadline runs from publication of the permit, not from when you notice the works. File at Tribunal Administrativo e Fiscal with your interest (light, privacy, distance).
- Damage to your propertyCracks, water, a fence removed: document, notify the neighbour in writing, your insurer, and consider an expert report.
- Ignored: Segurança Social — apoio judiciário / Ordem dos AdvogadosAfter the objection decision, the administrative court; legal aid if needed.

❓ Frequently asked
Can I stop works that annoy me but are legal?
No. Noise and hours are separate rules (see the noise page); the permit covers the building itself.
They built too close to the boundary
Zoning rules set distances; the authority enforces them if you report. Old buildings may have prior rights.
Can I look at the plans?
Yes — permits and plans are public documents in every EU country; you may need to ask in writing.
