Legal analysis: building a house in rural areas does not need the signature of neighbors, but needs to apply to the village collective economic organization or the villagers' Committee, and can only be built after approval. There is no requirement for neighbors to sign in the conditions and approval procedures for rural residents to apply for homestead. However, it is necessary to consider whether the building behavior will obviously affect the ventilation, lighting and drainage of the surrounding residents. If there is no influence or the influence is not obvious, then you don't need to get the consent of your neighbors. If so, you must get the consent of your neighbors. Consent can be obtained through negotiation and compensation. According to the law, the neighboring owners of real estate should correctly handle the neighboring relationship in accordance with the principles of favorable production, convenient life, solidarity and mutual assistance, and fairness and reasonableness. The construction of buildings shall not violate the relevant national engineering construction standards, and shall not interfere with the ventilation, lighting and sunshine of adjacent buildings.
