Get a building permit May seem complex, but with the right information, the process becomes much simpler. Being a specialist in legal law passionate about town planning, I guide you through the essential steps to succeed in your request. Prepare to dive into the exciting world of the French administration!
What is a building permit and when is it necessary?
The building permit is an essential administrative authorization for many construction projects. It guarantees that your project complies with the town planning rules in force. During my career, I saw many cases where the absence of a permit caused serious problems for owners.
Projects requiring a building permit
Here are the main cases where you will need to obtain a permit:
- Any new construction exceeding 20 m² of floor or ground floor surface
- Extensions of more than 40 m² in urban areas (20 m² excluding urban area)
- Destination changes with facade modification or carrier structure
- Swimming pools over 100 m² or with coverage exceeding 1.80 m high
Special cases and exceptions
It is essential to note that certain constructions of less than 5 m² are exempt from formalities. But, do not be mistaken: even for these small projects, it is necessary to respect the local urban planning rules. I have often advised my clients to check with the town hall, even for apparently minor projects.
The importance of compliance with rules
Failure to comply with the rules can lead to heavy sanctions, ranging from fine to demolition. Unfortunately, I saw cases where owners had to destroy constructions made without authorization. This is why I cannot insist too much on the importance of following the procedure well.
How to prepare and submit your building permit file
The preparation of the file is a crucial step. A well -mounted file considerably increases your chances of quickly obtaining your license. Here are the key elements not to be overlooked.
Essential documents to provide
Your request file must include:
- A duly completed cerfa form
- A field situation plan
- A mass plan of constructions
- A plan in the field of land and construction
- A descriptive project notice
- A plan of facades and roofs
- A graphic document in the environment
- Photographs of the near and distant environment
Remember that if the total surface of your project exceeds 150 m² after work, the use of an architect becomes compulsory. This collaboration can be precious to optimize your project and facilitate the obtaining of the permit.
The filing of the file and the instruction deadlines
Once your file is complete, place it in town hall in 4 copies. The investigation time is generally 2 months for a detached house and 3 months for other projects. During this period, take the opportunity to inquire about the necessary guarantees for your mortgage, if you need it to finance your project.
| Project type | Investigation time |
|---|---|
| Individual house | 2 months |
| Other projects | 3 months |
Possible results and their implications
At the end of the investigation, several decisions are possible:
- Pure and simple agreement
- A motivated refusal
- An agreement with prescriptions
- A tacit agreement in the absence of an answer within the deadlines
If not agree, do not forget to display the permit in the field for the duration of the work. This step is crucial because it marks the start of the period of appeal of third parties, which is 2 months.
After obtaining: the following steps and the points of vigilance
Obtaining the permit is only the start of the adventure. It is central to remain vigilant on several aspects to carry out your construction project.
Validity and extension of the permit
Your license is valid for 3 years and can be extended twice 1 year. Do not let these deadlines pass! I saw too much customers having to start the entire procedure again because they had been slow to launch their work.
Taxes and regulations not to be forgotten
Remember that obtaining a permit is accompanied by certain financial obligations. You will have to pay the development tax and the royalty of preventive archeology. In addition, for new constructions, an RT2012/RE2020 thermal study is compulsory.
If your project is in a protected sector, the opinion of the architect of the France buildings will be required. This step can extend the deadlines, but it is crucial to preserve our architectural heritage.
Management of potential changes and disputes
It often happens that changes are necessary during the project. In this case, it is imperative to file a modifying permit. Do not take the risk of making changes without authorization, the consequences may be severe.
In the event of a dispute with a neighbor or the town hall, keep in mind that the permit does not guarantee compliance with the rules of private law. I have often had to intervene in disputes between neighbors concerning constructions, even when the permit had been granted.
By following these tips and remaining attentive at each stage, you will maximize your chances of obtaining your building permit and carrying out your project. Do not hesitate to be accompanied by a professional to secure your approach. Good luck in your construction project!
