Do I Need a Permit for a Fence Replacement?
Often yes — many jurisdictions require permits for fence replacement even when the original fence was permitted, especially if the height, location, or material changes. Replacing 'like for like' in the same footprint is exempt in some cities but not others. The permit questions that matter: height limits, setback and sight-triangle rules at corners, and pool barrier requirements if the fence encloses a pool.

Height and location rules
Typical limits: 6-7 feet 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. Retaining-wall-plus-fence combinations are measured from the lower grade — a 3-foot wall with a 6-foot fence can be a 9-foot violation. HOAs often have stricter limits than the city; satisfy both.
Pool barriers
If the fence is the pool barrier, replacement must meet current pool code: 48-60 inch minimum height (varies by jurisdiction), self-closing self-latching gates opening away from the pool, no climbable horizontal members within the restricted zone, and maximum 4-inch gaps. Pool barrier inspections are strict because the failure mode is a child's drowning — this is the fence replacement most likely to need a permit and inspection.
Shared fences and neighbors
Boundary fences are typically shared responsibility under state 'good neighbor' fence laws — get the agreement in writing before building. Verify the property line with a survey, not the old fence (old fences are frequently off the line). If the neighbor's fence encroaches, the replacement is the moment to correct it — with a survey in hand.
The bottom line
Check whether your city requires a permit for fence replacement — height limits, corner sight triangles, and pool barrier rules are the triggers. Survey the line and get neighbor agreements in writing.
