How does the estimator calculate permit fees?
Washington cities set building permit fees from a fee table tied to the construction valuation of the work, a method that grew out of the model building codes. The table charges a base amount plus a declining rate per thousand dollars of valuation. Plan review is charged as a percentage of the building permit fee. Each city adopts its own table and adjusts it periodically, so the estimator applies a city factor to a common curve rather than copying any one city's schedule.
- Valuation. Your entry, or square footage multiplied by a typical Eastside cost per square foot for the project type. Projects measured per item, such as a beam or a seismic retrofit, use a typical project value.
- Base fee. A tiered curve: a higher rate per thousand dollars on the first $100,000 of valuation, lower rates above $100,000 and above $500,000.
- City factor. A multiplier for each city, reflecting where its fee schedule sits relative to the curve.
- Range. The low end is 85% of the result and the high end 120%, to cover differences in how cities count valuation and minor fees.
- Plan review. 65% of the building permit fee, a common ratio in Washington fee schedules.
- Review time. Typical weeks from complete application to issuance for the project type, adjusted for cities with longer queues.
What the estimate leaves out
- Electrical permits, which some cities issue and others leave to WA L&I.
- Plumbing and mechanical permits for new fixtures, ducts or equipment.
- Impact fees for schools, parks and transportation, which can apply to ADUs and new units.
- Utility connection charges for water and sewer.
- Critical-area, tree or shoreline review fees, and consultant reports such as geotechnical studies.
- State building code surcharges and technology fees added to each permit.
The fee data lives in one table inside this tool, so it can be updated when cities revise their schedules without changing anything else on the page.

Permit cost questions
Questions about permit fees and review time
What is construction valuation on a building permit?
Valuation is the estimated cost of the labor and materials for the work being permitted, excluding land and most design fees. Cities use it to calculate the permit fee. Some accept the applicant's figure; others apply their own cost-per-square-foot tables for additions and new construction, which can make the valuation higher than your contract price.
Why is plan review a separate fee?
Plan review pays for the city's examination of drawings and calculations before the permit is issued, while the permit fee covers inspections during construction. Most cities collect plan review at submission and the permit fee at issuance. If a project is withdrawn after review, the plan review fee is usually not refunded.
Why does Seattle take longer than Eastside cities?
Seattle reviews a larger volume of permits and has more overlays, including environmentally critical areas and landmark districts, that add review steps. Simple permits can still move quickly there, but full plan review for additions and DADUs typically takes longer than in most Eastside cities. Review times in every city change with workload.
Can I lower my permit fee by reporting a lower valuation?
No, and it can backfire. Cities can reject or adjust valuations that look low for the scope, often using their own cost tables. An understated valuation can delay intake or require resubmission. The reliable way to control permit cost is to keep the permitted scope clear and complete, so review finishes in one round.
