Special Management Area Permitting in Hawaii: A Builder's Guide

Who actually approves an SMA permit

County	SMA approving authority
Maui	Maui, Molokaʻi or Lānaʻi Planning Commission
Hawaiʻi	Windward or Leeward Planning Commission
Kauaʻi	Kauaʻi Planning Commission
Honolulu	Honolulu City Council

The state Office of Planning and Sustainable Development in Honolulu is the lead agency for the Coastal Zone Management program — it oversees consistency across counties, trains county staff, and publishes SMA guidance. It issues SMA use approval directly only inside the Kakaʻako and Kalaeloa Community Development Districts. For most projects, it never issues the permit itself.

The practical point: the county determines the calendar and the local application requirements, so a Maui SMA timeline does not predict a Big Island one, and budgeting a Big Island project against a Maui schedule is a real planning error.

The sequence, and how long each step takes

1. Pre-consultation. Draft Environmental Disclosure Document prepared; pre-consultation with the county. No filing fee at this stage.
2. Draft Environmental Assessment. Submitted to the county. The agency has 60 days to review and either accept or return comments.
3. Environmental Notice publication — 30 days once the draft is accepted.
4. Final Environmental Assessment. Public and agency comments folded in. Another 60-day agency review, then another 30 days published in the Environmental Notice.
5. SMA Major application. A Written Statement condensing the Final EDD is submitted with the application.
6. Site walk and public hearing at the county planning center, then a Council Committee briefing.
7. Approval — after which the design team takes final plans to the building department. The entitlement process and the building permit process are separate queues.

As a working estimate, the full EDD/SMA process runs 8 to 12 months, and can run to a year or more if significant agency, technical or community concerns arise.

What the studies actually involve

The environmental disclosure document typically requires: sea level rise analysis (3.2 ft for urban lots), a flood hazard report, a shoreline determination narrative, botanical and faunal review, CZM research including NOAA 6-ft surge, hurricane and tsunami analysis, an erosion and sedimentation control plan, historical and cultural research, and a Phase I environmental site assessment with HazMat review and historic aerial and topographic imagery.

Where projects stall

The single most useful thing to know: the process most often stalls waiting for 95% complete plans — not on agency review, but on the owner's own design team. Draftspeople running late, or owners still undecided on design, and the Final EDD cannot go to the Environmental Notice. Getting the design decided early is the single largest schedule lever an owner controls.

How this fits with the building permit

The SMA process runs through the county's land use division; the building permit runs through the building department. They are separate queues, and the SMA plans must match the building permit plans. Because of that, it generally does not make sense to submit for the building permit until SMA approval is in hand — building to a design before it has cleared SMA review risks permitting a set of plans that still has to change to match whatever conditions come out of that approval.
