Sometimes, depending on the project
Before building any deck attached to a house, or a detached deck or platform 30 inches or more above grade.
Issued byCounty of Hawaiʻi Department of Public Works, Building Division
By Mario Bailey, verified against official sources
Quick answer
Only DETACHED decks or platforms less than thirty inches above grade are exempt in Hawaiʻi County; the exemption still requires the deck to respect zoning yard setbacks, which the county tells owners to verify with the Planning Department. A deck attached to a dwelling, or a detached one 30 inches or higher, needs a building permit.
Typical threshold: height of a detached deck or platform; an attached deck is not exempt.

How to apply in Hawaii County
In Hawaii County, a residential deck permit application is a set of construction documents that show what will be built and prove it meets the IRC deck provisions. In practice that means a scaled site plan locating the deck and its setbacks, plus deck plans and structural details covering the footings, posts, beams, joists, ledger, guards, and stairs.
What most deck permit applications include:
- For Hawaii County, a permit application identifying the work, the deck's size (square footage), and whether electrical work such as lights or receptacles is included, submitted for plan review before construction begins (IRC R106).
- For Hawaii County, a scaled site plan (for example 1/4 inch to 1 foot) showing the new deck's location relative to the house, its overall length and width, and dimensioned distances from the deck to all property lines and other structures so required setbacks can be verified (IRC R106.1.1).
- For Hawaii County, a deck plan drawn to scale showing overall dimensions and the framing layout: joist size, spacing, span, and species; beam size and span; post size and height; and footing or pier size and depth (IRC R507.4 posts, R507.5 beams, R507.6 joists, R507.3 footings).
- For Hawaii County, a section or side elevation with connection details showing the ledger attachment to the house band joist with flashing, the fastener or bolt schedule, joist hangers, post-to-beam and post-to-footing connections, and the required lateral load connection (IRC R507.9 ledger connection, R507.9.2 lateral connection, R507.2.4 flashing).
- Footing sizing derived from tributary area, the soil bearing value, and design loads per IRC Table R507.3.1, with footings shown bearing on undisturbed soil at the frost depth required by the jurisdiction (IRC R507.3).
- Details for the guards required where the walking surface is more than 30 inches above grade, and for the stairs and handrails, showing guard height and opening limits, stair riser and tread dimensions, and handrail location (IRC R312 guards, R311.7 stairs and handrails).
- For designs that fall outside the prescriptive R507 tables (for example multi-story or stacked decks, or a ledger attached to a cantilever), engineered and stamped structural plans are submitted in place of the prescriptive details (IRC R507.1 and R301).

Inspections and closing out your permit
In Hawaii County, deck work is inspected in sequence as it is built: the footings before concrete is placed, the framing before the decking boards go down, and a final inspection once the deck is complete. Each stage checks the items that would be hidden or unsafe if missed.
- Footing or pier inspection in Hawaii County: after the holes are dug and any forms or reinforcing are set but before concrete is placed, the inspector checks footing depth and diameter, a flat undisturbed bearing surface, and that the holes are free of water (IRC R109.1.1 foundation inspection; R507.3 footings).
- Framing inspection in Hawaii County: after the deck is framed but before the decking conceals it, the inspector verifies the ledger attachment and its flashing, the fastener and bolt schedule, joist hangers and metal connectors, post-to-beam and post-to-footing connections, and the lateral load connection; call it before decking is installed (IRC R109.1.4 frame inspection; R507.9 ledger and flashing).
- Final inspection in Hawaii County: after the deck is complete and before it is used, the inspector confirms guard height and opening limits (a 4 inch sphere must not pass, 4 3/8 inch at stairs), stair riser and tread dimensions, handrail height and graspability where there are 4 or more risers, stair landings, and required stair lighting (IRC R109.1.6 final inspection; R312 guards, R311.7 stairs and handrails).

- Where do you apply for a deck permit in Hawaii County?
- You can apply through the Hawaii County permit portal or contact the County of Hawaiʻi Department of Public Works, Building Division directly. The links are listed on this page.
- Can a homeowner pull a deck permit themselves in Hawaii County?
- Under Hawaii law (HRS 444-2(7), 444-2.5, 444-9.1, 444-23(e)): Hawaii lets owners or lessees build or improve residential or farm buildings for their own use, or for use by their grandparents, parents, siblings, or children, without a contractor's license, as long as the building is not offered for sale or lease. The owner must register for the exemption with the county when applying for the building permit, supervise the work, hire licensed subcontractors for any licensed work, and use licensed electricians and plumbers for electrical and plumbing work unless the owner holds that license. Selling or leasing the structure within one year after final county inspection is treated as evidence it was built for sale, unless the permit valuation was under $10,000, the buyer is the owner's employee, or the Contractors License Board finds an unforeseen hardship. A violation carries a fine of up to $5,000 or 50% of the permitted construction value, whichever is greater, for a first offense, and bars the owner from the exemption for three years. Confirm how Hawaii County applies this before you apply.
