Free Hawaii property lines map

Yes. This map draws Hawaii parcel boundaries from the Hawaii Statewide GIS Program's public statewide parcel layer (all 4 counties) on satellite imagery. It is free, with no account, no trial, and no app to install. Search an address or zoom in, then tap any parcel to see its acreage and parcel ID.

From the Hawaii Statewide GIS Program, which publishes the layer as a public web service. The map asks that service for the parcels in view each time you move it, so you see the state's current copy rather than a stored one. Hawaii identifies every parcel by its Tax Map Key (TMK), the number each county’s real property office uses; tap a parcel to read its TMK.

No. Parcel maps are drawn from deeds and tax records for assessment, and lines can be off by several feet or more, especially in rural areas. They are good for finding a property and getting a sense of its shape and size. For a fence, a building setback, or a boundary dispute, hire a licensed land surveyor, whose survey is the legal record.

They are good tools and they cover every county in the country, which is what their subscription pays for. If you only need Hawaii, the state already publishes the parcel lines for free, and this map simply puts them on satellite imagery you can search.
