Michigan Pool Fence Requirements & Regulations (2026)

Michigan Pool Barrier Law

Michigan has no standalone pool-fence statute. Residential pool barriers come through the Michigan Residential Code (MRC), and in 2025 and 2026 the question of which edition applies got complicated.

The state filed a 2021 MRC in May 2025, set to take effect on August 29, 2025. On July 7, 2025, the Michigan Court of Claims entered a stipulated order in two suits brought by the Home Builders Association and others against the Department of Licensing and Regulatory Affairs (LARA), temporarily preventing LARA from implementing the update while the litigation continues. LARA's rules page says that while the order remains in place, the 2015 versions stay valid and in effect. Local departments say the same: Troy's building department, for one, notes that the 2021 code is paused and the 2015 code remains in effect.

Under the 2015 MRC, pools are built to the 2015 International Swimming Pool and Spa Code (ISPSC). Cascade Township's pool checklist puts it plainly: per the 2015 MRC, all pool installations must comply with the 2015 ISPSC. Section 305 of that code sets the barrier rules most Michigan departments inspect against:

• At least 48 inches high, measured on the side facing away from the pool
• No opening a 4-inch sphere can pass through
• Gates that open outward, self-close and self-latch, and can take a lock
• No more than 2 inches between grade and the bottom of the barrier
• Chain-link openings no wider than 1.75 inches
• Horizontal rails less than 45 inches apart on the pool side of the fence, with gaps between vertical members no wider than 1.75 inches
• Doors from the house into the pool area alarmed, where the house forms part of the barrier

Public pools are regulated separately. Mich. Admin. Code R 325.2128 requires the owner of a public swimming pool to enclose it with a barrier at least 4 feet high, with self-closing, latching and locking entrances and no sliding doors.

Above-Ground Pools in Michigan

Under the 2015 ISPSC, an above-ground pool's own wall can be the barrier, but Michigan departments add conditions you should check before counting on it. White Lake Township accepts the wall only where the pool manufacturer approves it as a barrier and it stands at least 48 inches from ground level. Ladders or steps must be secured, locked, removed, or surrounded by their own compliant barrier.

Ann Arbor requires a 4-foot, non-climbable fence where the manufacturer's specifications do not allow the wall to serve as the barrier, and warns that standard chain link may not be acceptable. Waterford Township allows a barrier mounted on top of the pool structure, with no more than 4 inches between the pool and the barrier, and a 4-foot fence around any fixed or removable ladder.

Permits start early. Ann Arbor requires one for any pool 24 inches or deeper or holding more than 5,000 gallons, and says no pool should be filled until the required barriers are in place.

City & County Variations in Michigan

The barrier baseline is the same statewide, but townships and cities add their own zoning and enforcement rules. These are the ones we could source to the department's own documents.

Pool Fence Cost in Michigan

We found no published source that prices pool fences by state or city, so these are national installed ranges from our pool fence cost guide. Quotes where you live can land above or below them.

National typical installed ranges, not quotes. Multiply by your fence perimeter. Some sources include one gate in the figure; extra gates, permits and hard deck surfaces add to the total.

Michigan-Specific FAQs

Michigan Pool Fencing: A Paused Code Update and a 42-Inch Frost Line

Michigan's pool barrier rules are enforced by more than a thousand local units, but the rulebook itself is statewide, and right now it is the 2015 one. The 2021 residential code that LARA filed in 2025 is on hold under a court order, so a pool permitted in 2026 is reviewed against the 2015 Michigan Residential Code and the 2015 ISPSC. If a contractor quotes you a newer edition, ask why.

The local variation is in zoning and enforcement rather than barrier height. Among the documents we could source, townships differ on whether a powered safety cover can replace a fence (White Lake says no), how far a pool must sit from lot lines (5 feet in Waterford, 10 in White Lake), and whether the barrier needs its own permit. None of the Oakland County, Washtenaw or Kent County sources we checked sets a residential pool barrier above 48 inches.

The climate detail is the frost line. Mich. Admin. Code R 408.30522 amends the residential code so exterior footings and foundation systems extend 42 inches below grade, with room for the building official to adjust for soil, groundwater and freezing conditions. That rule is written for buildings, not fences, and no pool code sets a post depth. But a gate post that heaves an inch in March can stop a self-closing gate from latching, so ask your inspector what depth they expect for gate posts in particular.
