Ketchikan, Alaska Building Permit Guide

The City of Ketchikan’s Building Division (Public Works, 2930 Tongass Avenue, 907-228-4737) reviews plans, issues building and trade permits, inspects the work and issues the certificate of occupancy for property inside city limits. Applications are not filed at the Division: they go to the Ketchikan Gateway Borough Planning & Community Development office together with a Borough zoning permit application, and a typical house permit is ready 6 to 10 working days after the City receives the file. A $25,000 home project pays a $391.25 permit fee, with no separate plan review fee.

The City and the Borough are separate, unconsolidated governments: the Borough handles zoning, building height, setbacks and lot coverage inside the city, and the City enforces the building codes. Work that needs no City building permit can still need a Borough zoning permit (907-228-6610).

What requires a building permit in Ketchikan?

The City’s handouts list what needs a City permit inside city limits. Electrical, plumbing, gas, mechanical, elevator and fire protection work are all covered by a City building permit.

Other approvals that can apply: a side sewer permit to connect to or cap a City sewer, a traffic permit for work in a right of way, an excavation permit, a demolition permit, the Borough zoning permit, a Borough floodplain development permit in a mapped flood zone, and Army Corps of Engineers, Department of Environmental Conservation or state transportation approvals.

Alaska's state codes exempt homes of three units or fewer, so residential permits exist only where a city or borough has adopted a code. Contractor licensing applies statewide, and the Fire Marshal reviews larger buildings outside deferred jurisdictions. Alaska rules

Ketchikan building department: who handles permitting

The Building Division of the Public Works Department enforces the City’s adopted codes, reviews plans and inspects. The State Fire Marshal lists Ketchikan as a deferred jurisdiction, so the City, not the state, reviews commercial and multifamily plans inside city limits.

Permit types

Residential permits

Houses and duplexes are reviewed under the 2021 International Residential Code; a triplex or larger building counts as commercial work under the International Building Code. A homeowner may draw the plans for a house or duplex, or use a contractor or residential drafter, and the City may issue the permit to a homeowner for a single-family house, duplex, townhouse or condominium unit. Contractors on a home job of $10,000 or more need the state residential endorsement, and handyman work is capped at $10,000.

Commercial permits

Commercial plans must be sealed by an architect or engineer registered in Alaska, and a commercial permit is issued only to a contractor licensed under state law. Deferred submittals, such as truss calculations, must be listed on the plans and approved by the Building Official before the related inspection.

For tenant improvements and new commercial builds, Alliance handles commercial permit expediting through issuance. More on this: commercial building permits explained.

Permit life

Under KMC 19.04.090 (Ordinance 2005, 2025), a City building permit expires one year after it is issued, or when the work is finished if that comes first. The Public Works Director can grant extensions of up to 180 days each on a written request filed before it expires, if you show justifiable cause. The City’s 2023 handout also says a permit becomes invalid if work does not start within six months or stops for more than six months.

Alaska licenses contractors at state level. A general contractor building homes needs the residential endorsement, which requires an exam and a cold-climate construction course. Alaska rules

Ketchikan permit costs and fees

The Building Division’s Building Permit Basics handout (revised October 9, 2026) sets out how fees are worked out. The applicant gives a project valuation that includes materials and labor, and the Building Official can refuse a valuation that looks too low.

Worked examples from the handout: a $25,000 house project pays $69.25 for the first $2,000 plus $14 for each of the 23 further thousands, or $391.25. The same fee on a commercial alteration adds $254.31 of plan review, for $645.56. A new 4,000 sq ft wood-frame office is valued at $163.62 per sq ft times the 1.3 regional modifier, or $850,824, so it pays 1% ($8,508.24) plus $5,530.36 of plan review, $14,038.60 in all.

Each part of $1,000 counts as a full $1,000. Inspections outside business hours (two-hour minimum), inspections with no listed fee and extra plan review after plan changes cost $57 an hour, or the City’s full hourly cost if higher. A demolition permit is $25 (KMC 19.04.100). Fees are paid at City Hall, and the Finance Department must receive them in full before the permit is issued.

Trade permits and who may pull them

Trade permits that need no plan review, such as an electrical service upgrade, are handled faster than full building reviews.

Electrical and mechanical contractors need a state-licensed administrator, and electricians and plumbers need a state certificate of fitness. Alaska rules

How to apply for a Ketchikan building permit

Plan review times

The handout gives an average of 6 to 10 working days for a residential permit and up to 16 working days for a commercial one, counted from when the Building Division receives the file from the Borough. Incomplete submittals may be returned quickly when more information is needed.

Inspections in Ketchikan

Call for each inspection before anything is covered (907-228-4720 or 907-228-4737); the Division can reject work that was concealed before inspection. The handout lists these stages:

• Excavation, backfill, slope and drainage: inspected under the Site Development Permit by Public Works Engineering
• Buried utilities: water, sewer, conduit and sprinkler lines, inspected by the utility before backfill
• Foundation: rebar, anchor bolts and hold-downs before concrete, with setbacks checked against marked property lines
• Electrical, plumbing and mechanical rough-ins, then framing: the framing inspection comes after the rough-ins are in place, with straps, hold-downs and shear walls still visible; plumbing and mechanical lines are tested with water or air
• Drywall in fire-rated, shear wall and draft-stop assemblies, and insulation and vapor retarder before drywall
• Final: fixtures, outlets, smoke detectors, railings, siding, roofing, flashing, decks and address numbers

After the final, the Building Official issues the certificate of occupancy; a temporary certificate is possible only when all life safety items are met. Commercial projects add fire alarm, special inspection, grading, structural observation and accessibility sign-offs, with letters from the design professionals.

Frequently asked questions

Who enforces the building code in Ketchikan?

The City of Ketchikan’s Building Division, part of Public Works, at 2930 Tongass Avenue (907-228-4737), for property inside city limits.

Where do I submit a Ketchikan building permit application?

Not at the City office. Form #10 and the plans go to the Borough planning office in the White Cliff Building, with the zoning application and the owner authorization page, and reach the City Building Division only after zoning approval.

How much is a building permit in Ketchikan?

House and duplex permits come from the City’s valuation table with no plan review fee: a $25,000 project pays $391.25. Commercial work adds plan review at 65% of the permit fee.

How long does plan review take?

On average 6 to 10 working days for a residential permit and up to 16 working days for commercial, from when the City receives the file.

Can a homeowner pull a permit in Ketchikan?

Yes, for a single-family house, duplex, townhouse or condominium unit, and the homeowner may draw the plans. Commercial permits go only to state-licensed contractors.

Do I need a permit for a shed or deck?

Not for a detached one-story shed of up to 200 sq ft at a one- or two-family home, or a detached deck of up to 200 sq ft that is no more than 30 inches above grade and does not serve the exit door. Covered decks always need a permit, and a Borough zoning permit may still apply.

Which plumbing and electrical codes apply?

The 2021 Uniform Plumbing Code and the 2020 National Electrical Code, each with the City’s local amendments adopted in 2025. The City’s building permit covers the trade work, done by state-licensed trades.
