The ordinance, as written (Honolulu County) — Residential zoning districts - Purpose and intent
A copy, taken August 22, 2026. The version published by Honolulu is the one that governs, and it may have changed since. Check it before relying on anything here.
(a) The purpose of the residential zoning districts is to allow for a range of residential densities. The primary use is for dwellings. Other types of dwellings may also be allowed, including zero lot line and cluster arrangements. Non-dwelling uses that support and complement residential neighborhood activities are also permitted.
(b) The intent of the R-20 and R-10 zoning districts is to provide areas for large lot developments. These areas would be located typically at the outskirts of urban development, and may be applied as a transitional district between preservation, agricultural, or country zoning districts, and urban zoning districts. They would also be applied to lands where residential use is desirable but some development constraints are present.
(c) The intent of the R-7.5, R-5, and R-3.5 zoning districts is to provide areas for urban residential development. These districts would be applied extensively throughout the city.
