My family lives in Qinhuai District, Nanjing, and there are obvious cracks in the roof. What department should I call?

You can find a property. If there is a crack in the floor of the new house, you can complain to the quality supervision station of the Construction Bureau, and then find the director to dock with the design unit, and the design unit will issue a specific design plan.

Apply for housing quality appraisal and deal with it according to the appraisal results. If there are quality problems, the developer should pay compensation. If negotiation fails, the developer can sue the court for rights protection.

After the developer repairs the housing quality problems, the buyers can also ask for some compensation. The items are as follows: lost time; Travel expenses; Decoration cost: material cost, labor cost of decoration personnel, etc. Housing quality problems cause damage to indoor facilities and appliances. If you want to check out, you can claim the time difference loss of the house (the court may reject it). You can ask them to change a suite (which is rare at present), but there is still a legal basis. After the house is changed, the seller can claim the loss of the renovation cost of the original house.
