Check the zoning on a specific property

Zoning is assigned parcel by parcel. To see the district, lot size, and land details for any Hawaii property, look it up by its Tax Map Key (TMK).

This is a plain-English overview, not legal or zoning advice. Districts, permitted uses, and minimum lot sizes change and vary by county. Always confirm the current rules for a specific parcel with the relevant county planning department (on Oʻahu, the Department of Planning & Permitting) before relying on them.
