Honolulu Subdivision Plat and Lot Size Rules
This guide explains how subdivision plats and minimum lot-size requirements are applied in Honolulu, Hawaii, who enforces them, and where to get official rules, forms, and decisions. It covers the Department of Planning and Permitting (DPP) procedure for preliminary and final plats, how zoning and the Revised Ordinances of Honolulu affect lot sizes, and practical steps for applicants and neighbors.
Overview of Subdivision and Lot-Size Rules
Subdivision in Honolulu requires plat approval before creating new legal lots; minimum lot areas and dimensions depend on the property's zoning district and any special area plans or overlay rules. Consult the municipal code and DPP guidance for district-specific standards and required approvals. [1]
When a Plat or Subdivision Approval Is Required
- Creation of two or more legal parcels from a single tax map key generally requires subdivision approval.
- Boundary line adjustments that change legal lot configuration may trigger plat or map filing requirements.
- Condominium maps or air-rights subdivisions follow related but distinct filing rules.
How Zoning and Minimum Lot Sizes Apply
Minimum lot size and frontage are set by zoning district rules in the municipal code and may be influenced by special plans, slope and drainage requirements, and utility availability. If a property is in a planned development or special district, additional standards can apply. [2]

Applications & Forms

Applicants commonly must submit a completed subdivision application, a survey/plat prepared by a licensed surveyor, drainage and grading plans (if applicable), and required approvals from utility agencies. For localized form names, fees, and electronic submission instructions, see DPP forms and the subdivision guidance. [1]
