Grant County, WA Fence Regulations: Height Limits (2026)

Development Services applies a two-tier height standard to residential fences countywide. A fence within the front yard setback cannot exceed 4 feet, while fences in side and rear yards can rise to 7 feet but may not extend forward into the front yard setback line. Fence height is measured to include everything on top of the fence line, so posts, lattice toppers, or other attachments count toward the 4 or 7 foot cap; a homeowner cannot install a 6-foot panel fence and then add a lattice topper to push it higher without exceeding the residential limit.

Commercial and industrial parcels get a flat 7-foot cap within any required setback, rising to a required 10-foot setback where the property adjoins a residential zoning district so landscaping and visual screening can be installed; commercial fences may also carry up to 18 additional inches of ancillary material such as stranded wire on top of the 7-foot fence. 110, and the code is explicit that no variance from that clearance requirement will be granted for public safety reasons. 245. Permitted fence materials are wood, masonry, wire, or dense landscaping; fences built of tires or other salvage materials never designed as structural fence or building components are barred outright.
