Summary
Dayton's adopted residential code requires a barrier at least 48 inches tall around every outdoor pool, spa, or hot tub, with gaps too small for a 4-inch sphere and self-latching gates.
An outdoor swimming pool, including an in-ground, above-ground or on-ground pool, hot tub or spa, shall be provided with a barrier which shall comply with the following:
1. The top of the barrier shall be at least 48 inches (1219 mm) above grade measured on the side of the barrier which faces away from the swimming pool. The maximum vertical clearance between grade and the bottom of the barrier shall be 2 inches (51 mm) measured on the side of the barrier which faces away from the swimming pool. Where the top of the pool structure is above grade, such as an above-ground pool, the barrier shall be permitted to be at ground level, such as the pool structure, or mounted on top of the pool structure. Where the barrier is mounted on top of the pool structure, the maximum vertical clearance between the top of the pool structure and the bottom of the barrier shall be 4 inches (102 mm).
2. Openings in the barrier shall not allow passage of a 4 inch diameter (102 mm) sphere.
3. Solid barriers which do not have openings, such as a masonry or stone wall, shall not contain indentations or protrusions except for normal construction tolerances and tooled masonry joints.

Full Breakdown
Dayton's own modifications to the 1999 Ohio Residential Code, enacted locally in R.C.G.O. § 153.03 (which replaces Chapter One of the residential code and was adopted by Ord. 29119-95), apply to swimming pools, spas, and hot tubs at one-, two-, and three-family dwellings. The barrier must stand at least 48 inches above grade with no more than a 2-inch gap at the bottom, block passage of a 4-inch sphere, limit chain-link mesh to 1 1/4 inches, and give access gates a self-closing, self-latching mechanism that opens away from the pool. A pool with a certified power safety cover, or a spa/hot tub cover meeting ASTM F1346-91, is exempt from the barrier requirement.
Violations & Fines
An outdoor pool, spa, or hot tub without a compliant 48-inch, 4-inch-gap barrier and self-latching gate violates the adopted residential code and can hold up final inspection or certificate of occupancy until corrected.
