Building a deck typically requires a permit if it is attached to the house, over 30 inches off the ground, or exceeds a certain square footage (often 200 sq ft).
Set by local rules
Do you need a permit for Deck Construction in Honolulu County?
In Hawaii, there is no single statewide rule for a Deck Construction; whether you need a permit is decided locally in Honolulu County.
There is no single statewide building code, so the rule is set by your local jurisdiction; most still require a permit for any deck attached to the house or more than 30 inches above grade. Because Hawaii leaves this to local jurisdictions, the reliable answer comes from Department of Planning & Permitting. Zoning setbacks apply either way.

Code Compliance & Inspections
Because Hawaii sits in a hurricane-prone zone, the Hawaii State Building Code requires exterior work to use wind-rated materials and proper anchoring (such as tie-downs and impact-rated components) to pass inspection.
HOA & Historic District Approvals
In highly urbanized counties like Honolulu County, municipal bureaucracy is only the first step. You will almost certainly need written approval from your Homeowners Association (HOA) before applying for a city permit. Additionally, if you live in a designated historic district, the local architectural committee holds veto power over your Deck Construction.
