Wenatchee, Washington Building Permit Guide

Wenatchee’s Building Division, part of Community Development, issues permits for residential and commercial construction inside the city limits, reviews the plans, inspects the work and processes mechanical, plumbing and fire sprinkler permits. Applications, payments and inspection requests go through the City’s SmartGov Permit Center. Electrical work is permitted and inspected by the state Department of Labor and Industries (L&I). Plan review costs 65% of the building permit fee, and a 5% technology surcharge applies to the building fees.

Building Division staff work from City Hall, 301 Yakima Street, Monday to Friday from 7 a.m. to 4 p.m., and answer 509-888-3244 and PermitCenter@WenatcheeWa.Gov. Chris Hanson is the Building Official. The city had 35,547 residents in the Census estimate for 2025.

Wenatchee permits cover work inside the city limits; Chelan County Community Development permits the county’s unincorporated land.

What requires a building permit in Wenatchee?

The City’s rule of thumb is that a permit is needed for any building or structure that is erected, enlarged, altered, repaired, moved, converted or demolished. Chapter 2.04 of the Wenatchee City Code (WCC) rewrites three of the residential code’s exemptions and two of the building code’s, and the City’s Building FAQ lists the result.

Wenatchee’s local amendments

The construction codes are the State Building Code Council’s. WCC 2.04 adopts them “as the same exists now or may hereafter be amended”, although its text still names the 2018 editions; the state’s 2021 codes have applied statewide since March 15, 2024. The City sets its own fence and shed rules, requires Class A, B or C roof coverings, requires an architect’s stamp on buildings with more than four dwelling units, sets fees in WCC 1.99, and runs zoning, shoreline and critical areas review.

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.

Wenatchee building department: who handles permitting

The Building Division routes each application to the other City departments that must sign off: Planning (zoning, shorelines, SEPA), Public Works (engineering review, right-of-way, land surface modification and utility service) and Fire for sprinkler and fire code permits. Planning answers 509-888-3256.

Permit types

Residential permits

SmartGov holds Wenatchee’s application forms: a residential building permit application for a single-family house, duplex or townhouse, a residential alteration and addition permit, a manufactured home application and a residential questionnaire, plus handout #19 on residential submittal requirements, a sample site plan and the 2021 residential energy code worksheets. The portal will not let you submit until the required documents are uploaded, and each permit type states which items may be deferred. The City also offers permit-ready accessory dwelling unit plans of 400, 600, 800 and 1,200 sq ft, each with a version drawn for the wildland-urban interface.

Ordinance 2026-15 sets flat fees for several house jobs: a residential re-roof is $100 ($200 for a commercial roof), a wood stove, gas stove or gas fireplace $100 (gas piping extra), an emergency escape window $200, a residential pool $250 ($450 for a commercial pool), a retaining or rockery wall $250, any demolition $100 and a sign $100 per sign. Placing a manufactured home costs $300 for a single wide, $400 for a double and $500 for a triple. The City’s permit-ready detached ADU and cottage plans are valued at a fixed $60,000 each, with a $100 plan check fee, and certifying an adult family home or a residential daycare costs $200.

Commercial permits

Commercial projects use the commercial building permit application, the commercial questionnaire, the architectural plan check form, a separate tenant improvement application and a special inspection form; a kitchen hood worksheet goes with mechanical permits, and each commercial kitchen hood is $200, with rooftop HVAC units at $100 below 2,000 CFM and $150 above. Public Works engineering review of a commercial or industrial application is $200 below $300,000 of value and 30% of the plan check fee above it, a $100 scanning fee applies when electronic copies are not submitted with a commercial application, and a temporary certificate of occupancy costs $300 for projects valued up to $5 million, $750 up to $10 million and $1,000 above that. Fire construction permits (WCC 1.99.050) include NFPA 13 sprinkler systems at $150 plus $1.50 per head, NFPA 13D or 13R systems at $100 plus $1.50 per head, fire alarm systems at $100 plus $2 per component and underground fire lines at $200.

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

What comes before the building permit

Planning reviews every building application, residential or commercial, for zoning: $100 for a project valued up to $200,000, $300 from $200,001 to $500,000, and above that 15% of the building permit review fee, capped at $2,000. Planning also administers the City’s shoreline master program: a written shoreline exemption is $300 and an administratively approved shoreline substantial development permit $500, and the Planning Division posts the joint aquatic resources permit application (JARPA) with its shoreline checklist. Public Works issues right-of-way permits ($50 base fee, plus $50 for a traffic control plan, $50 for a sidewalk inspection, $100 for a driveway inspection and $150 for a curb ramp inspection), street cut permits (from $300 for the first 50 feet of trench, doubled where the street’s pavement condition index is 71 to 85 and tripled at 86 to 100) and land surface modification (grading) permits, which cost $50 below 200 cubic yards and $250 or $450 with review for larger jobs; its engineer also reviews each residential building application for $100. Where a lot is not on sewer, the Chelan-Douglas Health District’s On-Site Septic Program reviews the system.

Wenatchee permit costs and fees

Building fees are set in WCC 1.99.040 as rewritten by Ordinance 2026-15, which the City Council adopted on August 27, 2026 and which takes effect 30 days after approval and publication; the eCode360 copy of the code had not yet been updated on October 30, 2026. A 5% technology surcharge is added to every fee in the building, planning, public works and fire fee sections. Valuation follows the latest ICC building valuation data or a designer’s figure the Building Official accepts: alterations are valued at 30% of new construction, residential garages at 85% of the Group U rate, residential carports and covered decks at 65%, and uncovered decks at 50%.

Worked example. A detached ADU built from the City’s permit-ready plans is valued at the fixed $60,000, which falls in the $50,001 to $100,000 band: $643.75 plus 10 × $7 gives a building permit fee of $713.75, and its plan check is the flat $100. The 5% surcharge on those two fees adds $40.69. Planning review ($100) and engineering review ($100) each carry their own 5% surcharge, adding $210, so the City’s fees come to $1,064.44 before plumbing, mechanical and L&I electrical permits.

Fee waivers exist too: planning and public works fees can be waived for an owner-occupant earning no more than 80% of the Chelan County median whose project is a South Wenatchee housing rehabilitation loan, a nonprofit’s sweat-equity home or a state Connecting Housing to Infrastructure Program project, and the Council may waive building permit fees to repair fire, flood or other disaster damage.

Trade permits and who may pull them

Plumbing and mechanical permits, including gas piping, kitchen hoods and rooftop units, are Wenatchee permits applied for in SmartGov, and fire sprinkler permits are processed through the Building Division under the fire code fees in WCC 1.99.050. Wiring is the state’s job here, since L&I runs electrical permits for every Chelan County city, and WCC 2.04 itself requires an L&I electrical final inspection in any building where circuits have been added or altered, requested by the electrical contractor or person permitted to do the wiring.

How to apply for a Wenatchee building permit

Review, corrections and what causes delay

An application is not complete, and review does not start, until its fee has been received (WCC 1.99.040). Revisions after the permit is issued are billed at $100 an hour with a one-hour minimum. Repeat house plans save plan review money only within the same code cycle; when the state adopts new codes, a new plan set and full plan check fee are required.

Inspections in Wenatchee

Inspections are requested through SmartGov. A request in by 4 p.m. is scheduled for the next business day, one made after 4 p.m. two business days later, and the first final inspection must be requested two full business days ahead. Inspections outside normal hours, when approved, cost $150 an hour with a two-hour minimum, and re-inspections $100. The electrical final comes from L&I, whose East Wenatchee office at 519 Grant Road is open Monday to Friday, 9 a.m. to 4 p.m. The City’s design values for plans are a 40 psf roof snow load, 85 mph wind with exposure C, seismic category C for houses and D for commercial buildings, an assumed soil bearing of 1,500 psf, an 18-inch frost depth for footings, and water lines at least 3 feet deep (5 feet under a driveway).

Wenatchee permit search and official resources

SmartGov’s advanced search and reports (inspection cards, inspection history, issued permits by department) cover permits in the system, and its parcel search shows permit information by property. For flood insurance, Wenatchee takes part in the federal program on FEMA maps dated January 6, 1994, and the City charges $100 for an elevation certificate.
