The Short Answer
Fences under 6 feet in rear or side yards are typically permit-exempt in Nixa; any fence in a front yard, corner-lot sight-line, or over 6 feet (or over 4 feet if masonry) requires a permit. All pool barriers require a permit regardless of height.
Nixa's local zoning code, adopted from Missouri model ordinances and the IRC, distinguishes fences by location and height—a critical point that sets Nixa's enforcement apart from some neighboring jurisdictions that apply a blanket 6-foot height cap with fewer location-based exemptions. In Nixa, the City of Nixa Building Department applies a two-tier system: rear and side-yard fences under 6 feet are administratively exempt (meaning you can build without filing paperwork), while front-yard fences of any height, corner-lot sight-triangle fences, and all fences 6 feet or taller in any yard must be permitted. Additionally, Nixa sits in FEMA flood zones in portions of the city (particularly near the Sac River floodplain); if your lot is in a designated flood zone, fence footings and materials may trigger additional floodplain-overlay reviews. Masonry or mortared stone fences over 4 feet require a footing and engineering detail regardless of location, since they function as retaining walls under Missouri building code. Pool barriers—even 4-foot chain-link—always require a permit and an inspection of gate self-closing and self-latching hardware, per IRC AG105.

What happens if you skip the permit (and you needed one)

Nixa fence permits — the key details

Nixa's Building Department administers fence permits under the City's adopted zoning code and references the 2015 International Building Code (IBC) and International Residential Code (IRC) for technical standards. The primary permit threshold in Nixa is six feet in height for side and rear yards; anything taller requires a permit and a site plan showing property lines and proposed fence location. Front-yard fences—including those on corner lots—are subject to sight-line rules and require a permit at any height to ensure the fence does not obstruct traffic-sight triangles at intersections. This is critical in Nixa because the city has narrower streets in older neighborhoods (particularly south and east of downtown), and sight-line violations can result in a permit denial and forced relocation or removal. Masonry fences (mortared stone, brick, concrete block) over 4 feet are treated as permanent structures and require footing details and, for anything over 6 feet, a structural engineer's seal. The reason: loose soil (Nixa's dominant Loess formation, which is prone to settlement) can undermine shallow footings, causing wall failure.
