Honolulu County provides expedited permitting for residential solar PV up to 20 kW under ROH Sec. 18-5.10, with solar readiness mandated island-wide for new single- and two-family dwellings.
ROH Sec. 18-5.10 gives qualifying clean energy projects, including residential solar photovoltaic systems up to 20 kW, expedited review through the Department of Planning and Permitting. Installations must also comply with ROH Chapter 16 (Building Code) and Chapter 17 (Electrical Code). Honolulu Building Code Sec. R408 requires new single- and two-family dwellings countywide to reserve space for a 5 kW AC PV system (solar readiness). ROH Sec. 2-38.1 directs municipal facilities to deploy solar PV. HRS Chapter 269 (Secs. 269-101 to 269-111) sets the state renewable portfolio context.
Installing solar PV without required permits or inspections can trigger stop-work orders, removal requirements, and fines under ROH Chapter 16 and Chapter 17.
