Katy requires a building permit before construction or installation of any in-ground or above-ground residential swimming pool within city limits.
The City of Katy has adopted the 2021 International Swimming Pool and Spa Code through Ordinance 3116 (October 23, 2023), and integrates pool permits into its broader building regulations. Permit applications must be submitted in person to the Permit and Building Services Division at Katy City Hall, 901 Avenue C, with site plans, structural details, electrical layouts, and barrier plans. The standard residential swimming pool permit fee is $110, plus a $30 application preparation fee. Inspections are required at multiple stages, including pre-pour, plumbing, electrical bonding, and a final inspection before the pool can be used.
Beginning pool construction without an approved permit, skipping required inspections, or installing a pool that fails to meet ISPSC or barrier standards can result in stop-work orders, fines, and required corrective work.
