Legal analysis: At present, the living environment of some old residential quarters is still relatively poor. If we want to improve people's living environment, we must carry out renovation, but before the renovation of the residential quarters, we must get the consent of the owners, and at least more than half of the owners can agree before construction can begin.

because all the expenses for the renovation of the residential area are borne by the owners, if the owners don't agree, then the related expenses will not be made up.

moreover, the renovation of the residential area is a big project, and the renovation project must be registered with the local housing authority and approved by the relevant government departments before construction can begin.

legal basis: article 49 of the civil code of the people's Republic of China. if the parties conclude a contract in the form of a contract, the contract shall be formed when all the parties sign, seal or fingerprint it. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it.

a contract shall be concluded in writing as stipulated by laws and administrative regulations or agreed by the parties. if the parties fail to do so in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
