Redwood City FAQ
Do I need a permit for a pool in unincorporated San Mateo County?
Yes. The County Planning and Building Department requires a building permit for swimming pools and spas, plus a boundary survey because pools, pool houses and cabanas are listed as projects requiring a survey.
Does the County set the pool fence rules?
