Missouri City's Swimming Pools & Spas: The Rules That Matter

Every city handles swimming pools & spas a little differently. In Missouri City, Texas, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Safety Rules

Key details: Drain Covers: VGB-compliant required. Electrical: GFCI protection required. Door Alarms: Required where home is barrier. Code Reference: Chapter 14, Article VII.

Failure to install or maintain required safety equipment can lead to citations, fines up to $500 per day, and shutdown of the pool until corrections are made and reinspected.

Compared to other cities, Missouri City takes a harder line on safety rules. The enforcement and penalty structure reflects that.
