Can't shrink a building lot below the minimum size
Read the official text at hawaiicounty.gov ↗This rule stops people from making a building lot smaller than the minimum size set by the zoning rules. If a lot is already smaller than the minimum, it cannot be made even smaller. There is one exception for lots reduced by street plans or public land purchases.
