Provisional reception of a new apartment: what changes compared to a house

Apartment provisional reception is not like that of a single-family home: it splits in two. On one side your private lot (the apartment you buy), on the other the common areas of the building (roof, facades, hall, lift shaft, parking). This dual dimension changes everything — responsibilities, signatories, deadlines, recourses. For an off-plan apartment buyer, understanding this legal architecture is the condition for a successful new apartment reception. The firm observes every year co-owners who discover too late that they did not sign the right reception, or that they never received the minutes for the common areas.

Why two separate receptions in co-ownership

The principle of dual reception in co-ownership stems directly from the Belgian Civil Code (Book 3 on property, recodified in 2020) and from the Breyne Law of 9 July 1971 when the property is sold to be built. The building legally consists of two sets: the private areas (your apartment, your cellar, your parking space) and the common areas (load-bearing structure, roof, facades, stairs, lift, collective boiler room, communal garden).

Each set obeys a distinct regime. You sign the private reception of your lot alone — it is your property, you are the sole interested party. The reception of the common areas, however, binds all co-owners, so it is signed by the provisional syndic appointed by the developer, then by the Co-owners’ Association once constituted at the notary. This mechanism is explained in the official documentation of the FPS Justice on real estate.

This duality has a practical consequence: you can have a perfectly received private apartment but disastrous common areas (defective roof waterproofing, non-compliant lift), and vice versa. The two sets of minutes are independent and must be obtained separately.

Private areas, common areas: who signs what

In practical terms, the boundary between private and common areas is set out in the base deed filed with the notary — the founding document of the co-ownership that defines, lot by lot, what belongs to whom. Anything outside your lot is common by default: common floors, load-bearing walls, roof, exterior facade, vertical technical ducts, collective evacuation conduits.

For the private reception, you (and you alone) sign the minutes with the developer. You record there the reservations specific to your lot: paint, parquet, taps, sanitary, equipped kitchen if included, glazing, private ventilation. Refer to our provisional reception checklist so as not to miss anything.

For the reception of common areas, the developer convenes the provisional syndic (often designated by themselves in the base deed). The minutes are signed between these two parties. You, as an individual co-owner, are not a signatory — but you have the right to attend as an observer if you make a prior written request. This point is crucial: without participation of the co-owners, the provisional syndic (linked to the developer) may be tempted to sign too quickly. Require a copy of the common-areas minutes within 15 days, and read it line by line. To go further, consult our dedicated cluster common areas reception.

The three typical families of defects in collective housing

The firm’s experience on over 200 new apartment reception files reveals three families of recurring disorders that single-family homes hardly know.

Acoustics first. Standard NBN S 01-400-1 sets the requirements for residential buildings: 54 dB for airborne noise between dwellings, 58 dB for impact noise. A sloppy partition, a poorly laid floating screed, an unsealed penetration around a pipe and sound transmission becomes unbearable. Acoustic defects are extremely difficult to prove after moving in: demand a standardised acoustic test from the pre-reception if you have the slightest doubt, and record the reservation in the minutes. Otherwise, the defect will be almost impossible to attribute to the contractor six months later.

Ventilation next. Single-flux (system C) or double-flux (system D) ventilation systems are mandatory in new EPB construction. Obstructed vents, insufficient flow rates, non-operational summer bypass, missing filters: so many defects that immediately degrade air quality and promote humidity.

Waterproofing finally, particularly at suspended terraces, balconies and joinery joints. A poorly executed terrace can flood the apartment below from the first storm. These are also potentially ten-year disorders (see ten-year liability) — hence the importance of detecting them in the minutes.

Breyne Law security deposit, common areas and shares

The Breyne Law applies fully to the purchase of a new apartment sold off-plan: 5% of the price blocked as a security deposit (article 12), mandatory completion guarantee, payments according to progress strictly framed. The security deposit covers your lot AND your share of the common areas in proportion to your shares (the thousandths of co-ownership that measure your weight in the building).

Concretely: if you hold 75/1000ths of the building and the common roof shows a waterproofing defect costed at €30,000, your due share is €2,250. But beware: you cannot act alone against the developer on a defect of the common areas. You must mandate the syndic, or wait for the co-owners’ association to decide collectively in general assembly. This is a decision-making bottleneck that the firm regularly sees blocking the lifting of common reservations for over a year.

For purely private defects, the mechanism is simpler: registered formal notice, lifting of reservations within the deadline of the minutes, failing which activation of the security deposit via the guarantor bank. See Breyne Law security deposit for the procedure.

Apartment-specific pitfalls to avoid

• Signing the private reception without seeing the common-areas minutes: if the roof leaks, your ceiling leaks too. Demand both sets of minutes before final signing.
• Accepting a provisional syndic who stays 5 years: the law requires the convening of the constitutive GA of the co-owners’ association as soon as the building is occupied. Do not let a syndic linked to the developer settle in long-term.
• Neglecting the acoustic test: it is the most litigious defect and the most expensive to correct afterwards (up to €15,000 to redo a floating screed).
• Underestimating ventilation: an unbalanced system C creates negative pressure, odours, mould in cold corners.
• Forgetting parking and cellar: these are private outbuildings to inspect with as much rigour as the home.

How to secure your apartment reception

A joint pre-reception audit (private + reading the common-areas minutes if available) is the best prevention. The Mon Etat Des Lieux firm intervenes via Breyne Law assistance to formalise enforceable reservations on your lot and alert the syndic about problematic common areas. You can also consult our provisional reception expert service or request a free quote within 24h. Better to invest €600 in an expert on D-day than €6,000 in proceedings two years later.
