State law usually sets the floor for what local governments must allow. Your city or county can still apply objective standards, so confirm the local rules as well.

Swimming Pool in California: common questions
Does California have a statewide swimming pool law?
A pool built at a private single-family home after January 1, 2007 must have at least one of seven approved drowning-prevention safety features, including an enclosing fence with a self-closing, self-latching device, removable mesh fencing, an approved safety cover, exit alarms on doors, or an alarm in the pool.
Does the state law replace my city or county rules?
Usually it sets a floor, not a ceiling. A statewide statute typically tells local governments what they must allow, while your city or county can still apply objective standards such as setbacks, height and utility connections. Local rules cannot usually contradict the state mandate, but they can add reasonable requirements.
What should I confirm locally before I start?
Ask for the adopted barrier standard, including minimum height, gate and latch requirements. Confirm whether door alarms, window restrictions or a safety cover are required. Check setbacks, utility clearance and whether the pool counts toward lot coverage. Ask which inspections are required before the pool is filled or energised.
