Do I Need a Permit for a Fence?
Usually yes for fences over a height threshold (commonly 6-7 feet), and always when the fence is near a property line, in a front yard, around a pool, or in a historic district. Many cities exempt low backyard fences from building permits but still enforce zoning: height limits, setback from sidewalks, visibility triangles at corners, and HOA rules. Pool fences have their own strict code requirements everywhere.

Height and location rules
Typical zoning: 6 feet max in side and rear yards, 3-4 feet in front yards, with corner lots subject to sight-triangle restrictions that keep fences low near intersections. Masonry walls (block, stone) almost always need a building permit and engineered footings above 3-4 feet — they are retaining structures as much as fences, and wind loads on solid walls are significant.
Pool barrier requirements
Pool fences are life-safety items: 48-60 inches minimum height (varies by jurisdiction), self-closing and self-latching gates opening away from the pool, no climbable horizontal members within the restricted zone, and maximum 4-inch gaps. Inspectors check pool barriers specifically — this is not a detail to improvise, and most drowning-prevention codes are written from hard experience.
Property line pitfalls
Build on your side of the line: a fence even inches over the property line can trigger a neighbor dispute or an adverse possession claim. Get a survey if the line is uncertain — it costs less than moving a fence. Shared fences with neighbors should have a written agreement on cost and maintenance; handshake deals on boundary fences fail at exactly the wrong moment.
The bottom line
Check zoning height limits, corner sight triangles, and HOA rules before building — and pool barriers have strict life-safety codes. Survey uncertain lines; it is cheaper than moving the fence.
