Carrez & sale of apartment in Soissons: all you need to know
You are considering selling an apartment to Sour (02200)? The Carrez Law is an essential element to know — it imposes obligations to measure the private surface, with significant consequences in case of error or omission. CLOVIS immo guide you to ensure that your sale is conducted in full compliance.
🔎 What is the Carrez Act? (legal framework)
The Carrez Act, enacted on 18 December 1996, requires the seller of a lot of condominiums to mention private area exact accommodation in all sales documents (promise of sale, compromise, authentic act).
The purpose of this obligation is to protect the buyer from overestimation of the surface, a determining criterion for the price and value of the property.
🏘️ What property is subject to the Carrez Law?
- All in condominium (apartments, studios, lots, etc.), when the private area is ≥ 8 m2.
- Commercial or professional condominium premises, or horizontal condominium lots.
On the other hand, the Carrez Law does not apply to the sales of single houses not subject to condominiums, land, car parks or garages, or lots less than 8 m2.
📐 How is the "Carrez" surface calculated?
The Carrez surface corresponds to the floor area of the enclosed and covered spaces, after deduction of the surfaces occupied by: walls, partitions, sheaths, stairs, door and window lights, etc.
The following are excluded from the calculation:
- Parts with a ceiling height of less than 1.80 m — Like some attic or attic.
- Balconies, terraces, cellars, garages, parking spaces, outdoor parking, sheds, open loggias, open verandas.
- Common areas, cellars, car parks and non-private annexes.
Measurement must be rigorous — often performed by a professional (geometer-expert, diagnostician) — to ensure compliance and avoid litigation.
📝 Why is the notice of sale mandatory?
The law requires the Carrez surface to appear in the promise of sale, compromise and authentic act — without such a statement, the act may be annulled or called into question.
It is a guarantee for both the buyer and the seller: it secures the transaction, facilitates comparison between offers, and avoids bad surprises.
⚠️ Risks and consequences in case of error or omission
When an error has consequences
- If the actual surface area is less than 5% on the indicated surface, the buyer may request a reduction in the proportional price, and possibly a revision of the notary fees.
- If the surface is not mentioned at all in the deed of sale — in the case of a condominium property — The act may be challenged or even annulled.
🛡️ To protect yourself: use a professional, check the plans, be rigorous in the measurement. This secures the sale for all parties.
