Shed permit rules in Honolulu County, HI — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
Sheds and similar accessory structures on Oahu must meet yard and street setback requirements in ROH Sec. 21-4.30 and height limits in Sec. 21-4.60, with smaller sheds potentially exempt from building permits under Chapter 18.
Sheds are treated as accessory structures under the Honolulu Land Use Ordinance. ROH Sec. 21-4.30 establishes required front, side, and rear yards and street setbacks that vary by zoning district. Height limits apply under Sec. 21-4.60. A shed generally cannot be placed in a required front yard and must maintain minimum distances from property lines. Detached accessory structures under threshold sizes set by ROH Chapter 18 may be exempt from a building permit, but zoning setback rules still apply. Owners must verify their zoning district (R-3.5, R-5, R-7.5, R-10, R-20, AG, or Country) for exact dimensions.
Placing a shed in a required yard, exceeding the height limit, or skipping a required building permit can result in notices of violation, removal orders, and civil fines.
