Summary
Pool barrier gates in unincorporated Larimer County must open outward, be self-closing and self-latching. If the latch release is on the outside and not self-locking, it must be at least 54 inches high. Doors from the house to the pool need a listed water-hazard alarm.
Pedestrian access doors and gates shall open outward, shall be self-closing and shall have a self-latching device. Where a latch release on the outside of the barrier is not self-locking, it shall be at least 54" high.
Full Breakdown
Per the adopted 2021 ISPSC, pedestrian access gates open outward and are self-closing with a self-latching device. Where a latch is inside the barrier, openings within 18 inches of the latch are limited to 1/2 inch. Non-pedestrian utility gates stay locked when not in use. Where a dwelling wall serves as one side of the barrier, doors, gates, and operable windows within 48 inches of the finished floor that give direct pool access must have a UL 2017 water-hazard entrance alarm producing an audible warning; the alarm deactivation switch sits at least 54 inches above the floor.
Violations & Fines
Noncompliant gates or missing alarms fail the barrier inspection; the pool cannot be used until corrected under the building permit.
