Honolulu County's LUO Section 21-4.30 sets front, side, and rear yard setbacks for every zoning district across Oahu, with companion residential standards in ROH 21-3.70-1.
ROH/LUO Section 21-4.30 is the primary Land Use Ordinance section on required yards and street setbacks for all zoning districts on Oahu. Residential districts such as R-5 typically require a 10-foot front setback, 5-foot side yards, and a 5- to 10-foot rear yard depending on lot configuration. Corner lots carry two street setbacks. District-specific residential standards are cross-referenced to ROH 21-3.70-1. Certain permitted projections are allowed into required yards, including eaves, bay windows, and limited-height fences. Shoreline setbacks under ROH Chapter 23 and flood hazard rules impose additional limits in coastal and floodplain areas. Accessory dwelling units and ohana units must also comply.
Setback encroachments trigger LUO enforcement including stop-work orders, required demolition or relocation of the encroaching portion, civil fines that can exceed $1,000 per day, and a notice of violation recorded against the property title.
