Do I Need a Permit to Resurface a Swimming Pool? in Spanje
Pool resurfacing — replastering, re-tiling, or applying a new pebble or quartz finish to an existing pool shell — rarely requires a building permit because it is considered repair or maintenance of an existing structure. However, if the project involves modifying pool plumbing, adding new electrical connections (e.g., for LED lighting), changing the pool's shape or depth, or draining into the storm sewer, permits may be triggered. Some jurisdictions require a permit whenever the pool is fully drained, and the drained water discharge must comply with local stormwater ordinances.

Country-specific detail
In Spain, swimming pools are very common, especially in Mediterranean regions. Resurfacing an existing piscina — regresite (replastering with gresite mosaic tiles), applying new revestimiento (finish), or replacing the liner — is generally treated as obra menor or mantenimiento and typically does not require a licencia de obra. However, some ayuntamientos require a comunicación previa for any work involving pool drainage. If the work modifies the fontanería (plumbing) or instalación eléctrica (electrical system), the instalador autorizado must file the corresponding certificado. Discharge of aguas de vaciado (drained pool water) is regulated by local ordenanzas — chlorinated water typically must be directed to the red de saneamiento (sanitary sewer), not to cauces públicos or the storm system.
