Agence BnB · Commercialité · Paris · Version française
Need to compensate a change of use (housing-code regime)? Own commercial premises whose commercialité (commercial-use rights) could be worth a fortune? We work on both sides of the market — search, negotiation, legal security — on a success-fee basis.
Check this first
Is your project on non-residential premises? Switching to hotel-type accommodation (legal year-round Airbnb) requires no compensation — often hundreds of thousands of euros saved versus buying commercialité.
In Paris, converting a home into anything else (offices, short-term rental…) requires a change-of-use permit with compensation: creating housing in exchange, within the same sector. That exchange surface is the commercialité — you buy it from an owner who agrees to convert their commercial premises or offices into housing.
Two subtleties drive the entire price. The sector: in the reinforced compensation zone (most of the centre and the west), you must compensate 2 m² for every 1 m² converted — unless the seller is a social landlord, who counts 1 for 1. Hence the status of the seller: "social" commercialité costs more per m², but you need half as much of it. For short-term rentals, the compensation must additionally be located in the same administrative quarter.
Before buying commercialité, check the alternative. If your project concerns premises that are not housing, the change of destination to hotel-type accommodation requires no compensation — often hundreds of thousands of euros saved. We check this point systematically as part of the free assessment.
Ranges observed on the market (cross-checked against grids published by specialised intermediaries, Q4 2025), rounded — in € excl. VAT per m² to be compensated. There is no official grid: every sale is negotiated over the counter, depending on the exact sector, the volume and the timeline.

Since the Le Meur law, major French cities have been tightening their change-of-use rules: converting a home into a short-term rental there requires compensation. Ratios and prices observed in July 2026 — outside Paris, the market for commercialité titles is narrow or non-existent: compensation is most often provided "in kind" (converting premises into housing), and that is precisely where our planning expertise comes in.
Ratio · 1:1 within the same arrondissement — from the very first m² in the hypercentre (Presqu'île) and for companies
Metropolitan rules tightened on 01/01/2026: outside the hypercentre, compensation from 35 m²; individuals may get a one-off 9-year temporary permit. Narrow market (broker grids: €450-650 on the Presqu'île).
Ratio · 1:1 — equivalent habitable surface (−10% tolerance), same arrondissement group
Compensation required from the very first property since 29/04/2025 (AMP metropolitan rules of 27/02/2025, upheld in court June 2025). Nascent market, high observed prices.
Ratio · 1:1 in zones B and C — 2:1 (double surface) in zone A (city core), unless compensating with social housing
Compensation from the first property (2017 rules, tightened by July and September 2025 resolutions). No organised commercialité market: private deals, highly variable prices.
Ratio · 1:1 across the city — after the single temporary permit (3 years, non-renewable) per tax household
2026 rules (resolution of 05/12/2025): 671 permits/year quota in 4 high-pressure sectors (applications in February), litigation pending before the Conseil d'État. ~€7,500 processing fee.
Ratio · 1:1 (equivalent surface and quality) — 1.5:1 in the reinforced compensation sector (hypercentre)
Rules tightened by the Eurometropole on 19/12/2025, applicable to filings from 01/02/2026. No observed commercialité market: compensation in kind.
Ratio · 1:1 — at least equivalent surface, in the same commune (24 communes in the high-pressure zone)
CAPB rules in force since March 2023, definitively upheld in court. Massive effect: −92% of applications in year one. Compensation in kind, no title market.
Ratio · 1:1 — premises of equivalent quality and surface, in the same commune
Common EPT Paris Ouest La Défense rules (2019, amended 2023): compensation required from the first short-term rental in a second home.
Ratio · 1:1 — at least equivalent surface and quality, in the same commune
EPT Grand Paris Seine Ouest rules of 25/06/2025, in force since 01/09/2025: compensation from the first property.
Ratio · 1:1 — equivalent surface, no reinforced sector
CA de La Rochelle rules (2022-2023, tightened on 13/11/2025) applicable in 10 high-pressure communes.
Ratio · 1 : 1 — at least equivalent surface, within the same zone (city centre, faubourgs or rest of the territory)
Compensation regime adopted by Toulouse Métropole deliberation No. DEL-22-1077 of 20 October 2022 and in force since 1 November 2023; three compensation perimeters, with compensation required from the 1st dwelling for legal entities and from the 3rd dwelling for individuals (ground-floor premises cannot be used as compensation).
Ratio · 1 : 1 — at least equal surface, within the same administrative district or the PSMV perimeter
Compensation regime in force (regulation amended in 2025): a real and definitive authorization is conditioned on the concurrent conversion of non-residential premises into housing; compensation applies to legal entities and to individuals who cannot obtain the personal temporary authorization (4 years, non-renewable), the 2025 regulation additionally adding a 770-authorization quota zone without compensation.
A case apart — Annecy. Annecy (Grand Annecy, 27 communes) regulates through QUOTAS, not compensation: ~2,660 permits capped by zone, one active permit per person, valid 4 years. There is no commercialité to buy there — the challenge is securing one of the quota permits.
Indicative summary of the rules in force (July 2026), non-exhaustive and subject to change — every municipality can amend its rules at any time. Case-by-case verification is essential before any deal: that is the purpose of our free assessment.
