Twain Harte's Swimming Pools & Spas: The Rules That Matter

If you live in Twain Harte or are thinking about moving there, swimming pools & spas are one of those things you probably won't think about until they affect you directly. Twain Harte has 2 specific rules on the books covering different aspects of swimming pools & spas, and some of them might surprise you.

Fencing Requirements

Twain Harte pool barriers follow California's statewide Swimming Pool Safety Act (Health & Safety Code §§115920-115929) and California Building Code §3109, enforced locally by Tuolumne County Building & Safety. Pools deeper than 18 inches require a 60-inch enclosure with self-closing, self-latching gates and a latch at least 60 inches above grade. New or remodeled pools must have at least two of seven approved drowning prevention features.

Key details: Barrier Height: 60 inches minimum (HSC §115923). Bottom Clearance: 2 inches max above ground. Gap Rule: No openings passing a 4-inch sphere. Latch Height: 60+ inches above ground. Required Features: 2 of 7 per HSC §115922.

Failure to install a compliant barrier or the two required safety features will block final inspection on a new or remodeled pool. Tuolumne County Code Compliance (Chapter 1.10) can issue notices of violation, daily administrative fines, and abate unsafe pools as a public nuisance.

This is one of the stricter rules in Twain Harte's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
