When buying real estate in Barcelona — especially as a foreigner — urban planning checks are essential. Failing to confirm land use, construction legality, or zoning rules can lead to serious legal problems after purchase.
In this guide, we explain how your lawyer verifies urban planning and land status before you buy, and why these checks are a critical part of the due diligence process.
🏘️ Why Are Urban Planning Checks So Important?
In Barcelona, not all buildings or renovations are legal — and not all advertised homes are legally recognized dwellings. Urban planning issues can result in:
-
Fines or demolition orders
-
Inability to register the property
-
Difficulty reselling the property
-
Ineligibility for mortgage or insurance
These problems are surprisingly common in attics, ground floors, extensions, or historic buildings.
📋 What Does the Lawyer Check?
Your property lawyer will review municipal and cadastral records, and request information from the local Ayuntamiento (City Council). Key checks include:
✅ 1. Zoning & Land Classification
-
Confirms the land is classified for residential use (suelo urbano)
-
Verifies it’s not protected land or part of a development plan
✅ 2. Building Legality
-
Checks whether the property has the required building license (licencia de obras)
-
Verifies the construction complies with planning regulations
-
Confirms there are no open urban planning sanctions
✅ 3. Cédula de Habitabilidad (Occupancy Certificate)
-
Confirms that the home is legally habitable
-
Required for utilities and rental licensing
✅ 4. Licensing for Renovations or Additions
-
Reviews permits for past work (e.g., extensions, roof conversions)
-
Ensures compliance with local urbanistic codes
🧱 Common Legal Issues Detected
| Issue | Risk |
|---|---|
| Illegal attic or ground floor apartment | May be unregistered or subject to fines |
| Missing building license | May prevent title registration |
| No certificate of occupancy | Can’t connect utilities or rent legally |
| Built on protected land | May be impossible to sell or insure |
| Unreported renovations | May require retroactive permits or demolition |
🏛️ How Are These Checks Performed?
Your lawyer will:
-
Request urban planning certificates from the Barcelona City Council
-
Cross-check the property details with the Land Registry (Registro de la Propiedad) and Cadastre (Catastro)
-
If needed, consult with local architects or technical advisors
-
Communicate with the seller’s agent or notary to clarify discrepancies
🛡️ How to Protect Yourself as a Buyer
-
Never skip due diligence. Insist on a full legal review before signing an arras contract.
-
Hire an independent lawyer. Do not rely solely on the seller’s agent or notary.
-
Avoid buying based on listing photos. Always verify the property’s legal status — not just its appearance.
💶 What Do Urban Planning Checks Cost?
These checks are typically included in a lawyer’s due diligence service, but may also be itemized depending on the property type.
| Service | Typical Fee Range |
|---|---|
| Full legal due diligence | €1,000 – €2,500 |
| Urban planning certificate | Included or €150–€300 |
🔍 When Should These Checks Be Done?
Before you sign the arras contract. Once you sign and pay the deposit, it’s very difficult — and expensive — to back out, even if serious issues are discovered.
