Do you need a building permit in Unalaska, Alaska?

Unalaska requires a city building permit for a new home and for work that erects, alters, repairs, moves or demolishes a building or structure.1 Start with the Unalaska Planning Department at City Hall: plans must satisfy the zoning code before referral to Public Works for a building permit.2

Unalaska also requires separate plan review unless specifically exempted, and the owner must submit a self-certification statement.8 Residential-code plans may be submitted without a registered design professional’s stamp, but specified conditions or the Building Official’s discretion can require one.8

Who issues building permits in Unalaska?

Unalaska Public Works is the city building-permit contact; call 907-581-1260 or visit 1035 E. Broadway Avenue before starting building or excavation.1 Unalaska Planning handles the preceding zoning review and can be reached at 907-581-3100.2

Unalaska requires an excavation permit for digging on city-owned property or an easement, in the road or within a city right-of-way.1 The city lists a $500 residential Utility Inspection Card Deposit, refundable after Public Utilities completes service-installation inspections; that deposit is a separate budgeting item from the question of building-permit fees.1 Ask Public Works for the current building-permit fee and the inspections required for your project.

Does Unalaska have zoning, and what does your district allow?

Unalaska has municipal zoning inside its corporate limits, with an exception for Native Allotments and Restricted Deed Lots until unrestricted federal title is granted.5 Unalaska’s districts include Single-Family/Duplex Residential (SFD-R), Moderate-Density Residential (MD-R) and Holding (H), among other districts.9

Ask Unalaska Planning to identify the parcel’s district and provide the district text before choosing a building layout; the department supplies that text on request.2 Ask specifically about permitted dwelling types, lot size, setbacks and accessory dwellings. Unalaska Planning handles applications for zoning exceptions, which may be variances or conditional use permits.2

How do septic approvals and sewer connections work in Unalaska?

Alaska DEC oversees onsite wastewater systems inside Unalaska, while the city controls its wastewater-service connection requirements.34 A property with a wastewater main within 300 feet must apply to the city for wastewater service, subject to conditions on main-line extensions and utility easements; connection becomes mandatory when a main later comes within that distance.4

For an onsite system, qualifying authorization-by-rule installations can proceed without prior plan approval when standards and separation distances are met, but require electronic notice at least 24 hours before construction and subsequent documentation or registration.6 Systems outside those categories require prior written DEC approval.6 Resolve sewer availability with the city before paying for a septic design.

Can you live in an RV or tiny home in Unalaska?

We could not confirm general permission to live in an RV or tiny home on a private lot in Unalaska. Ask Unalaska Planning about your proposed dwelling, the parcel’s zoning district and any temporary occupancy while a home is being built. Unalaska requires zoning review of building plans before referral for a city building permit.2

Alaska’s owner-builder contractor-registration exemption is conditional and does not itself waive local building approvals or inspections.7 Unalaska’s plan-review requirement also contains specific exemptions rather than a confirmed blanket exemption for owner-builders.8 Ask Public Works to identify the approval path for your particular structure before purchasing or moving it onto the lot.

What are the steps before building a home in Unalaska?

First, meet Unalaska Planning at City Hall with your proposed development and ask for the parcel’s district requirements; zoning-compliant plans are referred to Public Works for a building permit.2 Next, resolve city wastewater service or the applicable Alaska DEC onsite-system approval route before construction.46 Then submit the city plan-review documents and owner self-certification, and contact Public Works before beginning construction or excavation.81

For a lot split or subdivision inside Unalaska, Planning requires a plat application and a preliminary plat prepared by a registered surveyor.2 For land outside city limits, use the Aleutians West Census Area guide to distinguish the surrounding area’s building-permit answer from Unalaska’s city requirement.10 Ask Planning about floodplain requirements and Public Works about private-well approvals before committing to a purchase; we could not confirm those parcel-specific requirements.

Watch-outs

  • Unalaska city building permits apply even though the surrounding unincorporated area has no area-wide building-permit requirement.110
  • Unalaska can require wastewater-service applications and sewer connection based on proximity to a city main, so an onsite septic proposal needs a city-service check first.4
  • Unalaska plan approval can be blocked by specified tax or business-license delinquencies.8
  • We could not confirm Unalaska’s general building-inspection or certificate-of-occupancy requirements; ask Public Works for the project’s inspection and completion requirements.1
