First of all, you should go to the National Land Office for the record, and the staff of the National Land Office will verify whether the land you need to build a swimming pool is within the scope of urban and rural construction planning. If so, you can go to the Land Bureau for the initial registration of land. Without any formalities, it is not allowed to destroy the original appearance of the land and build it illegally. Secondly, it is necessary to apply for the health permit of the health and quarantine department, the business license of the industrial and commercial tax department and the tax registration certificate. Thirdly, the swimming pool staff should go to the relevant epidemic prevention departments for health certificates, and the swimming pool should be equipped with professional lifeguards.
