CA AB470

Requires swimming pools and spas at private single-family homes to be equipped with at least 2 of 7 specified drowning prevention safety features (increased from 1) when a building permit is issued for new construction or remodeling.

Specifies 7 approved drowning prevention features including enclosures, mesh fencing, safety covers, exit alarms, self-closing doors, water detection alarms, or other equally protective means verified by testing laboratories.

Requires local building code officials to inspect drowning prevention features before issuing final construction approval.

Mandates home inspectors include a noninvasive examination of pools and spas to identify which drowning prevention features are present and report if fewer than 2 features are installed.

Removes exemption for political subdivisions that previously had their own swimming pool ordinances, making requirements statewide.
