Codes, exemptions & field inspections

Build to the adopted code. Verify every exception.

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 code baseline for Sitka City and Borough County.

Residential: 2021 International Residential Code excluding plumbing and electrical, 2021 Uniform Plumbing Code and 2020 National Electrical Code. Commercial: 2021 International Building Code, 2021 International Fire Code, 2021 International Mechanical Code, 2021 Uniform Plumbing Code, 2020 National Electrical Code and 2021 International Existing Building Code. Sitka's published structural criteria include 150 mph basic wind speed, 50 psf ground snow load and minimum 18-inch frost depth.

Inspection lane

The applicant must call the Building Department to schedule required inspections, generally giving one working day's notice. A plot plan is reviewed by Planning and Zoning and Building, usually in about two days; a no-charge foundation-only permit may then be issued, followed by complete plan review. Construction cannot begin until the building permit is in hand.

Minor-work playbook

Understand what may be exempt—and what is not.

Common Sitka permit exemptions include one-story detached sheds, playhouses and similar buildings up to 120 square feet; retaining walls no higher than 4 feet; platforms, walks, decks and driveways no more than 30 inches above grade; roofing that does not disturb underlying sheeting or framing; siding replacement; window replacement without framing or rough-opening changes; and fences no higher than 8 feet. Exempt work must still comply with zoning and setbacks.

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

Keep the work visible at every release point.

  1. 1

    Request with lead time

    The applicant must call the Building Department to schedule required inspections, generally giving one working day's notice. A plot plan is reviewed by Planning and Zoning and Building, usually in about two days; a no-charge foundation-only permit may then be issued, followed by complete plan review. Construction cannot begin until the building permit is in hand.

  2. 2

    Preserve access

    Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.

  3. 3

    Close the record

    Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.

Contractor verification

Verify the builder before the contract is signed.

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

Keep the parcel rules beside the building plans.

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.

How are inspections scheduled?

Construction cannot begin until the building permit is in hand.

Which codes and exemptions should I review?

Residential: 2021 International Residential Code excluding plumbing and electrical, 2021 Uniform Plumbing Code and 2020 National Electrical Code. Commercial: 2021 International Building Code, 2021 International Fire Code, 2021 International Mechanical Code, 2021 Uniform Plumbing Code, 2020 National Electrical Code and 2021 International Existing Building Code. Sitka's published structural criteria include 150 mph basic wind speed, 50 psf ground snow load and minimum 18-inch frost depth. Common Sitka permit exemptions include one-story detached sheds, playhouses and similar buildings up to 120 square feet; retaining walls no higher than 4 feet; platforms, walks, decks and driveways no more than 30 inches above grade; roofing that does not disturb underlying sheeting or framing; siding replacement; window replacement without framing or rough-opening changes; and fences no higher than 8 feet. Exempt work must still comply with zoning and setbacks.

Field sequencing matters

The inspector needs to see the work at the right moment.

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.
