HCC §25-5-51
How residential and agricultural districts are marked on the zoning map
Read the official text at hawaiicounty.gov ↗This section explains how the county labels residential and agricultural (RA) districts on the zoning map. Each RA district gets a symbol with the letters RA, a number, and a lowercase 'a'. The number tells you the minimum acres needed for each building site, like RA-1a means one acre per site.
