Walla Walla, Washington Building Permit Guide

In the City of Walla Walla, the Community Development Department (formerly the Development Services Department) handles permitting and inspections for all development inside the city limits: new construction, remodels, mechanical and plumbing permits, signs and land use. Since August 19, 2025, applications, payments and inspection requests have gone through the City’s online permit portal. Electrical permits come from the state Department of Labor and Industries (L&I). Plan review is 65% of the permit fee and is paid, with the state surcharge, when the application is filed.

The department is at 55 E. Moore Street, open Monday to Friday from 8 a.m. to 5 p.m.; payments are taken from 8 a.m. to 4 p.m. Reach it on 509-524-4710 or permits@wallawallawa.gov. The city had 34,058 residents in the Census estimate for 2025.

City permits cover land inside Walla Walla’s limits; Walla Walla County Community Development permits the county’s unincorporated land, and College Place, Prescott and Waitsburg are separate cities.

What requires a building permit in Walla Walla?

Walla Walla adopts the 2021 International Building and Residential Codes in chapter 15.04 of the Walla Walla Municipal Code (WWMC) without changing their exemption lists, so the residential code’s list applies to houses as written. The City’s amendments are about elevation in flood plains, appeals to the hearing examiner, plan preparation and fees.

What Walla Walla adds to the state codes

The codes themselves are the state’s 2021 editions, adopted by Ordinance 2024-01 along with the existing building, fuel gas, property maintenance, swimming pool and spa, and wildland-urban interface codes. Walla Walla decides the fee table in WWMC 15.04.050, who may hold a permit (the owner or the owner’s authorized agent), when a design professional must prepare plans, a one-foot freeboard in flood plains, a minimum roof snow load of 30 lbs per sq ft, and its critical areas and shoreline rules.

Washington has a mandatory statewide building code under chapter 19.27 RCW that every city and county enforces and may make stricter; electrical permits come from the Department of Labor and Industries unless the city runs its own program or Tacoma Power serves the site.

Walla Walla building department: who handles permitting

Community Development reviews building and land use applications and also handles SEPA, critical areas, shorelines, signs and annexations. Fire protection permits for sprinklers, alarms and smoke control are applied for through the Fire Department.

Permit types

Residential permits

The City publishes a residential plan review checklist, a basement conversion guide and an “Express Permits – Does Your Project Qualify?” handout in its building forms folder, and residential energy code worksheets on the building permitting page. Plans must use the City’s design values: a 30 lbs per sq ft ground and minimum roof snow load, 110 mph wind, seismic design category D, a 24-inch frost depth and ice shield underlayment.

Re-roofing is priced from a set valuation: $200 per roofing square (100 sq ft) for a tear-off and $100 per square for roofing over an existing roof. A 2,500 sq ft tear-off (25 squares) is therefore valued at $5,000, which gives a permit fee of $84.78 plus 3 × $16.95, or $135.63. Placing a manufactured home costs $113 for a single wide up to $450 for a quadruple wide, and demolition is $57 for each house or commercial building and $26 for each outbuilding.

Commercial permits

Commercial projects follow the commercial plan review checklist. WWMC 15.04 requires a Washington-licensed architect or engineer to prepare or oversee plans for any building with five or more dwelling units and for new commercial construction or commercial alterations that affect structural integrity or life safety systems. Construction documents must show the code analysis (construction type, occupancy, exits and occupant loads), structural and life safety design, ADA access, special inspections and any deferred submittals. The commercial state surcharge is $25. Fire protection permits for sprinkler, alarm, smoke control and gas detection systems are priced on the value of the system using the same valuation table as building permits, with plan review at 65% due at submittal; starting that work without a permit (except in an emergency) doubles the fee. Interim zoning first adopted on February 26, 2025 (Ordinance 2025-02) restricts the siting of new wireless communication facilities within or near residentially zoned property; Ordinance 2026-12, passed as an emergency measure on July 8, 2026, extended it until January 25, 2027 or until permanent code amendments are adopted. Developers of qualifying multifamily housing can apply for the City’s multifamily housing tax incentive under WWMC chapter 2.28, with a $500 application fee plus $100 for Walla Walla County. For fire flow, Walla Walla’s amendment to the fire code’s Appendix B sets the minimum at half of the model table’s value, but never less than 1,500 gallons per minute.

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

What comes before the building permit

Walla Walla administers its own critical areas ordinance: where a stream may cross a property, the City requires a field investigation by a qualified professional, usually a biologist, to locate the ordinary high-water mark before new development is designed. Land use review, SEPA and shoreline permits are handled by the same department. Older buildings have their own track: the Historic Preservation Commission keeps the Walla Walla Register of Historic Places under WWMC chapter 2.27 and processes Special Valuation applications, which give property tax relief to owners who substantially rehabilitate a historic property; it usually meets on the fourth Thursday of the month at 5:30 p.m. in the Council Chambers, 15 N. 3rd Avenue. In a designated flood plain the floodplain chapter and IRC section R322 apply, with the lowest floor at base flood elevation plus one foot and a sealed elevation verification before the footing and framing inspections.

Walla Walla permit costs and fees

Building fees are written into the code itself (WWMC 15.04.050) rather than a separate resolution. Valuation comes from the latest ICC building valuation data, which the City adopts automatically; carports, wood decks, covered patios and porches are valued at half of the Group U rate.

Worked example. A house remodel valued at $35,000 sits in the $25,000.01 to $50,000 row: $475.48 plus 10 × $12.26 ($122.60) gives a $598.08 permit fee. Plan review at 65% is $388.75, and with the $6.50 building surcharge the amount due at filing and issuance totals $993.33, not counting mechanical, plumbing or L&I wiring permits. The Building Official may refund up to 80% of a permit fee if no work is done, or of the plan review fee before review begins, on a written request within 180 days of payment.

Trade permits and who may pull them

Mechanical and plumbing permits are City permits with flat item fees. Wiring is permitted and inspected by L&I, which has no Walla Walla office; its nearest office is in Kennewick at 4310 W 24th Avenue (509-735-0100), open Monday to Friday, 9 a.m. to 4 p.m.

How to apply for a Walla Walla building permit

Review, corrections and what causes delay

WWMC 15.04 asks for construction documents detailed enough to show the entire project, and additional plan review caused by changes, additions or revisions is billed at $65 an hour with a half-hour minimum. Holders of permits processed before August 19, 2025 may still need to call the permit technicians to pay or book inspections.

Inspections in Walla Walla

Request inspections in the online portal or through the inspection request line, 509-524-4729 (inspections@wallawallawa.gov). Appeals of a building official’s decision go to the City’s hearing examiner and must be filed within 14 days. A reinspection is charged at $65 an hour when work called for inspection still cannot be approved after corrections, and the fee must be paid before further inspections are scheduled. Inspections outside normal business hours have a two-hour minimum.

A permit expires if work does not start within 180 days, if work stops for 180 days, or two years after issuance whether or not the work is finished; finishing then takes a new permit at half the original fee or a fee based on the remaining work, whichever is less.

Walla Walla permit search and official resources

Permit status is searchable in the City’s online portal; permits processed before August 19, 2025 are handled by the permit technicians at 509-524-4710. Walla Walla takes part in the national flood insurance program, and FEMA’s status book shows no special flood hazard area mapped in the city (all Zone C); the City’s freeboard and elevation rules still apply wherever a flood plain is designated.
