Before leasing a shopfront, check whether that unit can host your trade: converting a residence to a shop needs unanimous consent from owners in the same building; new oil-smoke restaurants are barred in residential buildings

Converting a residence into a shop needs unanimous consent from the other owners in the same building—one household against is enough to block it. Neighbors asking for restoration and damages will be upheld. Residential buildings and mixed-use buildings without a dedicated smoke flue may not open new oil-smoke restaurants; if found, you are ordered to correct first. Refuse and the shop is closed, with a fine of 10000–100000 yuan—renovation money and deposit may be lost with it.

Cost

No money. Before signing a lease, paying deposit, or renovating, spend a few hours on three checks. First, the use on the property certificate—residential or commercial. Second, whether the building is pure residential, mixed-use, or a standalone shop unit, and whether people live upstairs. Third, for catering: whether there is a dedicated smoke flue, then ask local market supervision whether a food business license can be issued. The hard part is verifying yourself when the landlord or agent says «no problem—the last tenant ran one».

Benefit

Civil Code Article 279: «An owner who changes a residence into business premises shall, besides complying with laws, regulations, and the management covenant, obtain unanimous consent from interested owners.» An SPC judicial interpretation is more specific. Other owners in the same building all count as «interested owners». Owners in other buildings in the same estate count only if they prove impact on their property value or living quality. Changing use without their unanimous consent: requests to stop, restore, or compensate for losses shall be upheld. Arguing «a majority of owners agreed» is not upheld. The Ecological Environment Code took effect 15 August 2026; the Air Pollution Prevention and Control Law was repealed at the same time. Code Article 250 bans new construction, renovation, or expansion of catering projects that produce oil smoke, odors, or exhaust in three places: (1) residential buildings; (2) mixed-use buildings without a dedicated smoke flue; (3) commercial floors in mixed-use buildings adjacent to residential floors. Violations: ordered to correct first; refuse → ordered closed, plus a fine of 10000–100000 yuan. The code also requires local governments to flag catering siting bans at registration. Applying for a food business license: premises must match the food types and volumes handled, and keep required distance from toxic or hazardous sites and other pollution sources. Conversely, if the premises themselves fail mandatory use conditions in laws or administrative regulations, you may terminate the lease—provided the inability to use is not your fault (nationwide).

Notes

«The last tenant ran one» does not mean you can—maybe nobody sued, or it opened before the code took effect. Management covenants may add further limits; ask property management for a copy before signing. If the unit can't be used that way and you need to end the lease and recover deposit and renovation losses, refusal by the landlord means litigation. Ordinary first-instance procedure starts at 6 months; lawyer fees are on you—so writing «if a license can't be obtained or the shop is ordered closed, the lease ends and deposit is returned» into the lease is cheaper. Which licenses you need: items 7 and 8. Primary beneficiary: yourself.
