Summary

Any swimming pool built in a licensed Rock Island County mobile home park must sit behind a fence or wall five to seven feet tall with gaps no wider than four inches, and self-latching gates locked whenever no adult is supervising. The rule sits inside the county's mobile home park design and construction code.

These county ordinances apply to unincorporated areas of Rock Island County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

(1) No public or private swimming pool shall be erected unless the same be entirely enclosed by buildings, fences, or walls not less than five nor more than seven feet in height and of such construction that a child may not reach the pool from the street or from any adjacent property without opening a door or gate, or scaling a wall or fence. (2) Holes or openings in the fence shall be four inches or less. Such fences or walls shall be equipped with self latching gates or doors. The latching device shall be located not less than four feet above the ground and shall be of a type that can be locked. All exterior doors or gates shall be kept locked at all times when not properly supervised by an adult having direct control over the activities herein. Swimming pool fences are in addition to individual site fences covered elsewhere in this chapter.

Full Breakdown

17(P) of the county's Mobile Home and Mobile Home Park Code requires that no public or private swimming pool be erected inside a licensed mobile home park unless it is entirely enclosed by a building, fence, or wall between five and seven feet tall, built so that a child cannot reach the pool from the street or an adjacent property without opening a door or gate or scaling the barrier. Any gaps or openings in the fence are capped at four inches, and the enclosure must have a self-latching gate or door with the latch mounted at least four feet above the ground and capable of being locked; every exterior door or gate must stay locked whenever no adult with direct control over the pool area is supervising it.

The ordinance treats this pool enclosure as an addition to, not a substitute for, the individual mobile home space fencing already required elsewhere in the chapter. 17(O) requires any approved park pool or bathing beach to be built and operated to the State Department of Public Health's Minimum Sanitary Requirements for the Design and Operation of Swimming Pools and Bathing Beaches, with separate plans submitted to the state before construction. Because both provisions sit inside Chapter 151's park design and construction requirements, they govern pools built within a licensed mobile home park in the unincorporated county, whether that pool serves the whole park or an individual resident's leased space.

Violations & Fines

Failing to fence a park pool to these standards is a violation of Chapter 151, which § 151.99 punishes with a fine of up to $500 for each violation. The Zoning and Building Department, which reviews and approves mobile home park design and construction plans before a license issues, can also refuse to approve a pool installation, or a park's overall license, until the required enclosure and self-latching gate are in place.

Frequently Asked Questions

How tall must the fence around a mobile home park pool be?
Between five and seven feet, per § 151.17(P)(1), and built so a child cannot reach the pool from the street or a neighboring property without opening a gate or scaling the fence.
How big can the gaps in the pool fence be?
No more than four inches, under § 151.17(P)(2), and the enclosure needs a self-latching gate with the latch at least four feet off the ground so young children cannot reach it.
Does the gate have to be locked all the time?
Yes, whenever an adult with direct control over pool activities is not supervising it. Section 151.17(P)(2) requires every exterior door or gate to the pool enclosure to be kept locked at those times.
Does this fencing rule apply to any backyard pool in the county?
No. It sits inside Chapter 151's mobile home park design and construction requirements, so it governs pools built within a licensed mobile home park in the unincorporated county, not pools at conventional single-family homes.
