Kailua construction follows ROH Sec. 21-4.30 yard and street setbacks, plus district-specific standards in 21-3.70-1 for residential zoning. Setbacks preserve light, air, and neighborhood character across windward Oahu.
ROH 21-4.30 sets the framework for required front, side, and rear yards across Kailua's residential zoning districts. Typical R-5 and R-7.5 lots require 10-foot front setbacks, 5-foot side yards, and 5- or 10-foot rear yards, with specific numbers varying by district class. Residential standards in 21-3.70-1 add impervious-surface limits and envelope-plane rules. Shoreline parcels near Kailua Beach and Lanikai face additional shoreline setback requirements under state law (HRS 205A) and SMA review. Accessory structures have reduced setbacks but still cannot encroach on easements. Pre-construction zoning verification is strongly recommended.
Setback encroachments can trigger stop-work orders, forced demolition or relocation, after-the-fact variance applications, and ongoing fines.
