Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
The DPP's current public materials reference the 2018 International Building Code adoption and Revised Ordinances of Honolulu Chapter 18; the complete 2026 code set was not identified on the public FAQ.
Inspection lane
Contact the assigned building inspector listed on the permit. Electrical inspection requests must be submitted at least 48 hours (two working days) in advance; general building-permit questions go to 808-768-8000, and permit status is searchable through the department's Building Permit Search.
Minor-work playbook
One-story detached accessory storage, tool, playhouse, or similar buildings serving Group R-3 homes are exempt when the aggregate floor area does not exceed 120 square feet. Agricultural structures qualifying under HRS 46-88 are exempt but must be declared and may not include plumbing or electrical work.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
Contact the assigned building inspector listed on the permit. Electrical inspection requests must be submitted at least 48 hours (two working days) in advance; general building-permit questions go to 808-768-8000, and permit status is searchable through the department's Building Permit Search.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.
Open planning reference ↗Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
City and County of Honolulu Department of Planning and Permitting, Building Division is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 808-768-8000.
The department states that review time is highly variable and depends on completeness, complexity, compliance, backlog, and outside-agency approvals.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
