Land Surveying in Honolulu County, HI

Hawaii maintains two parallel title systems — Land Court (Torrens) and Regular System — and the applicable system affects how boundaries are researched, what documents control the survey, and how the final plat is prepared or filed. A licensed Hawaii Professional Land Surveyor must work from the correct chain of title documents for each system. Confirm which system your parcel falls under early in project planning, as it directly affects research time and deliverable format.

Yes. Shallow basalt in upland zones can make setting stable benchmarks more involved, and monument recovery in some areas is limited. Crews establish vertical control tied to available National Geodetic Survey benchmarks or project-specific temporary benchmarks set in stable material. On sites with significant grade relief — common across Oahu — multiple instrument setups and careful loop closure checks are standard practice to maintain elevation accuracy across the survey area.

Honolulu's Department of Planning and Permitting typically requires a topographic survey and site plan meeting specific scale, datum, and content standards before a grading permit is issued. Required elements generally include existing contours, property boundaries, easements, and finished-grade design overlaid on survey base data. Requirements can vary by project type and zone, so we recommend confirming current DPP checklist items with your engineer of record before the survey scope is finalized.
