Renovation in France: Costs, Permits, and Advice for Dutch Owners

Are you Dutch and considering renovating a house in France? Whether it’s for a second home, a farmhouse to restore, or a city apartment, this article explains the regulations, tips for finding reliable contractors, and costs, to successfully prepare and complete your renovation without any unpleasant surprises.

Permits and Building Regulations in France

In France, urban planning rules are strict, especially for old buildings or those in protected areas. Here’s what you need to know to avoid fines or demolition.

For any renovation project that modifies the exterior appearance of the building, it is mandatory to request authorization from the local urban planning service. Depending on the criteria, this request will take the form of:

a building permit application file (Permis de construire – PC),
or a prior declaration of work (Déclaration Préalable – DP).

When do you need a building permit or a prior declaration?

Type of Work	Building Permit	Prior Declaration	No Formality
New construction (> 20 m²)	✅ Required
Extension (> 20 m² or > 40 m² depending on the house)	✅
Extension (< 20 m² or <40 m² if full surface< 150m²)		✅
Change of use (e.g., barn → housing) with facade or structural modification	✅
Facade modification (Windows, doors, skylights, blinds)		✅
External insulation		✅
Pool (> 10 m²)		✅
Facade maintenance			✅
Interior work			✅

Good to Know

Each municipality has different rules depending on local architecture, and specific environmental constraints (natural risks, etc.).These rules define:
- construction limits and maximum building heights,
- authorized colors and materials for facades, roofs, and fences,
- rainwater management,
- land/garden layout,
- number of parking spaces.
- ect.
In the same municipality, rules may vary by sector. In classified zones (safeguarded sectors, historic sites), any visible exterior modification must be validated by the Architects of France’s Buildings (ABF). The procedures are more complex (additional documents required) and the processing times are longer.
Houses over 150 m² require a French-registered architect for the building permit.
Processing times:
- 1 month for prior declarations,
- 3 months for building permits.
Cost: Filing an application at the town hall is free.

⚠️ Warning: You can only start work once the file has been validated by the town hall.

Penalties for Work Carried Out Without Authorization

Fine of up to €300,000.
Demolition of unauthorized work (at your own expense).
Retroactive regularization is possible but costly and time-consuming.

Tips for your Project

Carefully check local rules from the design phase to ensure your project complies with the PLU (Local Urban Plan).
Book an appointment with the municipality to check that your project follows the regulations.
Hire a french professional to avoid rejection of your application.

Finding a Reliable Contractor in France

Finding the right craftsman is the most crucial step to avoid budget overruns, delays, or poor-quality work.

How to Verify a Craftsman’s Reliability?

Criteria	To Verify	Where to Find the Information?
Registration	SIRET/SIREN number	Societe.com
Decennial insurance	Mandatory for work > €1,500	Request a copy
Certifications	Qualibat, RGE (Recognized Guarantee of the Environment)	Company website
Customer reviews	Ratings and comments	Google, Houzz, PagesJaunes
Detailed quote	VAT-exclusive price, VAT, deadlines, materials	Compare with other quotes
References	Similar projects completed	Request photos and client contacts

Red Flags to Watch Out For

Quote too low (risk of shoddy work or additional invoices).
No written contract (always require a signed quote).
Request for full payment before work begins (a maximum 30% deposit is normal).
Poor communication (vague answers, repeated delays)

Tips for Working with French Craftsmen

Speak French (or get help): Many craftsmen do not speak English or Dutch. Use Google Translate or hire an interpreter for important meetings.
Be clear about your expectations: Provide detailed plans and inspiration photos. Visit similar sites with the craftsman to avoid misunderstandings.
Schedule regular visits: Deadlines in France are often longer than in the Netherlands. A weekly visit helps monitor progress.
Usual pay in stages:
- 30% upon signing (deposit).
- 40% halfway through.
- 30% upon delivery (after verifying the work).

Tips to Save Money

Use local craftsmen: Avoid Dutch companies (unless specialized), as they often charge more.

Apply for subsidies: France offers financial aid (e.g., MaPrimeRénov’, Éco-PTZ, reduced VAT at 5.5%). (See maprimerenov.gouv.fr for more details.
Design and plan your project in advance with an architect or interior architect to avoid costly surprises during the work.
