Provisional reception of a new house: the complete guide in Belgium

The provisional reception of a new house is the most structuring legal event of the year following the delivery of new housing. It (1) triggers the post-reception warranties — warranty of perfect completion, two-year warranty, ten-year liability, (2) effects the transfer of ownership and risk in civil terms, (3) releases 40 to 50% of the Breyne Law security deposit (the balance at final reception), (4) records compliance or reservations in the minutes. This guide sets the 2026 framework for a serious new build reception in Belgium, from preparation to lifting of reservations.

Breyne Law and new house: an almost systematic framework

A new house built or sold in Belgium almost systematically falls under the Breyne Law (statute of 9 July 1971), whether as turnkey house reception, off-plan purchase or new villa reception built on your own land. The central criterion: a down payment is made before full completion of a dwelling intended for residential use.

This implies:

• Double reception: provisional (triggers the post-reception warranties) then final (1 year later, releases the balance of the security deposit).
• 5% security deposit of the price blocked at the notary or via an approved bank during execution. See Breyne Law security deposit.
• Completion guarantee: protection against the builder’s bankruptcy.
• Mandatory contract clauses: price, plans, specifications, schedule, revision formula capped at 80%. See article 7 Breyne Law.
• Staged down payments in accordance with article 9.

Require these protections before signature of the notarial deed, never after. The provisional reception minutes (see template and clauses) is the legal culmination of this process.

The 4 critical zones of a new house

At the new build reception, four families concentrate most of the detectable defects. A serious checklist covers these 4 zones with the same rigour:

1. Waterproofing (zone 1 — the most contentious)

Roof, sub-roof, rainwater downspouts, joints of exterior joinery, openings, perimeter waterproofing of terraces, façade-to-roof connection. Test if possible in rainy weather or by spraying water on sensitive zones. An infiltration discovered 18 months later is handled under the two-year warranty; but a major infiltration rendering the dwelling unfit for its purpose may qualify as ten-year liability.

2. Electrical compliance RGIE

Electrical panel, residual current devices, sockets (phase/neutral/earth tested with multimeter), light points, earthing. The RGIE compliance certificate is mandatory and must be delivered at reception. Without it, the property cannot be received as compliant and the electricity supplier often refuses to open the meter.

3. HVAC and EPC

Boiler or heat pump: commissioning, settings, maintenance booklet, manufacturer warranty. Ventilation: airflow at vents measured (anemometer), adjustment label. Hydraulic balancing of radiators or underfloor heating. EPC certificate: mandatory, must confirm the level announced in the contract. Absence or non-compliance = major reservation.

4. Flatness, plumb and finishes

Verticality of walls (tolerance < 5 mm/m), flatness of floors (2 m straightedge, < 3 mm), plumb of partitions, alignment of tiles, joinery clearances (3 to 4 mm), lock operation. Aesthetic defects are often wrongly considered “minor”: yet they all fall under perfect completion for one year and must be in the minutes.

Expect 30 to 80 reservations in the minutes for a standard house of 130 to 180 m² — this is the norm, not the exception. Beyond 100 reservations, the firm considers that the work is insufficiently finished and may advise refusing the reception or accepting it under major reservations.

Case study: 175 m² villa near Brussels

2024 file: new turnkey 4-façade villa 175 m², 4 bedrooms, geothermal heat pump, EPC A, southern suburb of Brussels. 4-hour provisional reception, expertise by the firm.

Minutes balance: 62 reservations recorded including:

• 9 major: roof terrace waterproofing, living room crack, bathroom ventilation defect, RGIE non-compliant (partial protective earthing), 2 non-functional sockets, EPC defect (post blower-door verification ongoing), 2 unbalanced heating points.
• 24 intermediate: detached tiles, joint alignment, poorly adjusted joinery, slow drainage.
• 29 minor: paintwork, finishes, interior door clearances.

Decision: reception under major reservations with a 60-day deadline for the 9 major and 120 days for the others. Contractual penalties activated. All major reservations lifted in 11 weeks, all others in 8 months. Final reception pronounced 12 months later with integral lifting minutes.

Without expert support, the buyer would reasonably have detected 15 to 20 reservations, missing in particular the 9 major ones. Estimated avoided loss: €22,000 to €35,000 over 5 years (intervention under warranty vs out of warranty).

Pitfalls to avoid

• Rushed reception (1 h for 150 m²): impossible to check everything.
• Trusting the builder for inspections: he is judge and party.
• Signing minutes without photo annexes: weakened probative value.
• Forgetting the certificates: final EPC, RGIE compliance, gas compliance, boiler maintenance booklet, as-built plans. Without these documents, reception should not be pronounced compliant.
• Accepting vague wording such as “paintwork to be redone” without location.
• Skipping the pre-reception: 3 to 4 weeks beforehand is the ideal time to flag defects still easily correctable. See how it goes.

Why an expert for a new house?

A serious provisional reception of a new house lasts 3 to 4 hours for a 150 m² house. An expert detects on average 3 to 5 times more defects than a lone buyer, and above all formalises the reservations within the legal framework of the Breyne Law and the Civil Code, securing their enforceability.

The firm Mon Etat Des Lieux offers a complete journey: (1) pre-reception (preliminary visit 3-4 weeks before delivery), (2) provisional reception (adversarial inspection, drafting of minutes with photo file), (3) follow-up of the lifting of reservations until final reception.
