Mission's Swimming Pools & Spas: The Rules That Matter

Every city handles swimming pools & spas a little differently. In Mission, Texas, there are 2 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.

Fencing & Safety Requirements

Mission regulates residential pool barriers through the building code adopted in Chapter 18, Article II of the City Code, which incorporates the International Residential Code (IRC) and its Appendix AG (swimming pool, spa, and hot tub safety). For multifamily, condominium, and HOA-owned pools, Texas Health & Safety Code Chapter 757 (Pool Yard Enclosure Act) imposes additional statewide barrier rules.

Key details: Local Authority: Mission City Code Chapter 18, Article II. State Floor: 2012 IRC (Texas LGC Sec. 214.212). Barrier Height: 48 inches minimum (IRC AG105). Trigger: Pool/spa water deeper than 24 inches. Gate Rule: Self-closing, self-latching, opens outward.

Pools constructed or maintained without the required barrier are subject to stop-work orders, denial of certificate of occupancy, and code enforcement citations under Chapter 18 of the Mission City Code. Class C misdemeanor citations for code violations in Texas municipal court can carry fines up to $2,000 per day for public health and safety ordinance violations. Multifamily pools out of compliance with Texas HSC Chapter 757 may face civil penalties and tenant remedies under state law. Drowning incidents at non-compliant pools can also create significant civil liability for owners.

Pool Permits

Mission requires a permit before building a residential swimming pool, charged as a flat $300 swimming pool permit fee, plus separate electrical and plumbing permit fees under the city's building fee schedule.

Key details: Pool permit fee: $300 flat fee. Electrical pool permit: $50. Pool plumbing permit: $58.50. Contractor liability insurance: $100,000 minimum. Unpermitted work penalty: doubles all permit fees.

Building without a permit doubles all permit fees under Sec. 18-34(d); noncompliant pool contractors also face red-tag stops and reinspection fees under Sec. 18-43.

The Bottom Line

Mission's swimming pools & spas rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Mission is broadly strict or permissive.
