Renton fences must meet RMC 4-4-040 standards for height, setbacks, structural soundness, sight triangles, and material limits barring barbed wire and electrified fencing in residential zones.
Renton Municipal Code 4-4-040 sets the general standards for all fences, hedges, and walls. Fences must be structurally sound, well maintained, and placed entirely on the owner's property unless shared with a neighbor. Front yard fences are limited to four feet; side and rear yards to six feet without a permit; taller fences require a building permit. Sight triangles at street intersections and driveways must be kept free of obstructions taller than 42 inches. Barbed wire, razor wire, electrified fencing, and fencing with sharp or hazardous tops are prohibited in residential zones and allowed only in industrial zones with administrative approval. Pool barriers must comply with the IRC Appendix G standards. Fences within critical areas such as wetland buffers, steep slopes, and shoreline jurisdiction require additional review. HOA covenants in subdivisions across Renton may impose stricter standards than the city code.
