How Birmingham Handles Swimming Pools & Spas: A Practical Guide

Birmingham maintains 137 local ordinances across all categories, and 5 of those deal specifically with swimming pools & spas. Here is a breakdown of what the city actually requires, what is prohibited, and where Birmingham falls on the strict-to-permissive spectrum compared to other cities.

Hot Tub Rules

Jefferson County treats public spas, hot tubs, and therapy pools the same as public swimming pools: they need engineer-stamped plans, a permit to construct, and an operational permit, and they are subject to the same water-quality and barrier rules. Private backyard hot tubs are not health-inspected, but if a residential spa lacks a built-in lockable safety cover it must be enclosed by a compliant pool barrier under the adopted residential code.

Key details: Public spas: Regulated as 'public pools' under JCDH rules Sec. 1.6. Permits: Permit to construct + operational permit (JCDH Sec. 1.11). Private spa exemption: ASTM F1346 safety cover exempts from barrier (IRC App. G). Water quality: Spa parameters set in JCDH Appendix B.

Operating a public spa without the required Jefferson County permits, or in violation of the water-quality or barrier rules, is unlawful and may result in the spa being closed until corrected or an injunction sought in Jefferson County Circuit Court. Residential spas without a compliant safety cover that also lack a code-compliant barrier violate the adopted IRC Appendix G.

Pool Permits

Birmingham does not require a building permit to construct a residential swimming pool, but the applicant must submit a site plan and obtain Zoning approval before starting work, and separate electrical and plumbing permits (with inspections) are mandatory. Public pools have a far stricter process: the Jefferson County Board of Health requires engineer-stamped plans, a permit to construct, and an operational permit before a pool may open.

Key details: City Code Section: Birmingham 2024 Technical Code Sec. 103.1.1, Exception item 13. Building permit: Not required for pools; electrical + plumbing permits ARE required. Pre-construction: Site plan + Zoning approval before starting work. Public pools: JCDH permit to construct + operational permit (Sec. 1.11).

Building a residential pool without the required electrical and plumbing permits, or without Zoning sign-off, violates Birmingham's Technical Code and can result in stop-work orders and corrective requirements from the Department of Planning, Engineering and Permits. For public pools, it is unlawful to construct, maintain, repair, or use a public pool in violation of the Jefferson County regulations, and the Board of Health may seek an injunction in Jefferson County Circuit Court; pools may also be closed until violations are corrected.

Fencing Requirements

Birmingham enforces the Alabama Residential Code (2021 International Residential Code, Appendix G), which requires every outdoor residential swimming pool to be enclosed by a barrier at least 48 inches high with no openings that pass a 4-inch sphere and a maximum 2-inch gap below the barrier. Public and apartment-complex pools fall under the stricter Jefferson County Board of Health rules, which require a minimum 4-foot fence with self-closing, self-latching, lockable gates.

Key details: Private pool code: IRC 2021 Appendix G, Sec. AG105.2 (adopted via Birmingham Tech Code Sec. (b)). Minimum height: 48 in. (private); 4 ft (public, JCDH Sec. 8.13.3). Gate hardware: Self-closing, self-latching, lockable. Opening limit: No passage of a 4-inch sphere; 2-inch max gap below barrier.

Residential pool-barrier violations are enforced by the Birmingham Department of Planning, Engineering and Permits through its adopted building/residential code; the Building, Code, or Fire Official may require corrective work. For public and apartment pools, the Jefferson County Board of Health may close a pool until corrections are made and may seek an injunction in Jefferson County Circuit Court for any violation of its regulations.

Compared to other cities, Birmingham takes a harder line on fencing requirements. The enforcement and penalty structure reflects that.

Safety Rules

Public, apartment, and condominium pools in Birmingham must be maintained to Jefferson County Board of Health standards: a minimum free available chlorine residual of 1.5 ppm tested at least three times daily, pH kept between 7.2 and 7.8 and tested at least twice daily, and water clear enough that a marked disc is visible through 15 feet of water. Private residential pools are not subject to this health-department monitoring but must keep their safety barriers and self-latching gates compliant.

Key details: Chlorine residual: Min. 1.5 ppm free available, tested 3x daily (JCDH). pH range: 7.2-7.8, tested at least 2x daily. Clarity: Marked disc visible through 15 ft; turbidity max 2 ppm. Cleaning: Pools cleaned and vacuumed daily (JCDH Sec. 8.17).

It is unlawful to construct, maintain, repair, or use a public swimming pool or spa in violation of the Jefferson County regulations; the Board of Health may obtain an injunction in Jefferson County Circuit Court. A pool found to present a health hazard must be closed until corrections are made and reopening is authorized by the Jefferson County Department of Health.

This is not one of those rules that cities tend to ignore. Birmingham actively enforces its safety rules requirements.

Above-Ground Pools

Under the residential code Birmingham adopts, an above-ground pool whose wall serves as the safety barrier must have a ladder or steps that can be secured, locked, or removed to prevent access, or be surrounded by a fully compliant pool fence. As with in-ground pools, no building permit is needed to install an above-ground pool, but a site plan, Zoning approval, and electrical permits/inspections are required.

Key details: Governing code: IRC 2021 Appendix G, Sec. AG105.2 item 10 (adopted by Birmingham). Ladder rule: Lockable, securable, or removable to prevent access. Alternative: Surround pool with a compliant 48-inch barrier. Permits: No building permit; site plan, Zoning, electrical permit required.

An above-ground pool whose access ladder cannot be secured, locked, or removed and which is not otherwise surrounded by a compliant barrier violates the adopted IRC Appendix G and may be cited by the Birmingham Department of Planning, Engineering and Permits. Installing the pool's electrical equipment without the required permit and inspection also violates the Technical Code.

The Bottom Line

Birmingham is tougher than many cities when it comes to swimming pools & spas. Out of the 5 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Birmingham, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

These rules come from Birmingham's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
