Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Public Works/Zoning: 651-430-4300; Public Health and Environment/SSTS: 651-430-6655
Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.
Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact Public Works/Zoning: 651-430-4300; Public Health and Environment/SSTS: 651-430-6655.
For county conditional-use applications, the Planning Advisory Commission holds a public hearing within 60 days after staff determines the application complete; Board of Adjustment matters generally have 60 days to decide, with a possible additional 60-day extension. No ordinary building-permit timeline is published because municipalities issue those permits. The county encourages online or in-person SSTS submissions for the quickest processing but publishes no fixed routine duration.
Building inspections must be scheduled with the city or township building official. Washington County Public Works/Zoning conducts inspections for Development Code compliance; call 651-430-4300. SSTS installation inspections must be scheduled at least 24 hours before the work or inspection by calling Public Health and Environment at 651-430-6655; residential tank inspections may use the county's Survey123 remote-inspection process. Compliance inspections are required before septic-property sale or transfer unless the county's three-year existing-system or five-year new-system certificate exceptions apply.
Washington County does not issue building permits; its official permit page directs applicants to the city or township where the property is located. The county administers its Development Code in retained unincorporated areas and countywide SSTS and buffer functions, including subdivision, shoreland, floodplain, mining, buffer, and official-map regulations. The applicable Minnesota building-code edition and local amendments must therefore be confirmed with the municipal building authority; the county does not publish a separate county-enforced 2026 building-code edition. Building-permit exemptions are determined by the applicable city or township because Washington County does not issue building permits. For county authority, the Development Code applies only to retained unincorporated areas and specified functions; properties outside the county's shaded zoning-map areas should be checked with the township. No broad county cosmetic-maintenance exemption list was published. County SSTS permits are required for new septic tanks or soil-treatment areas, repairs or replacements, and changes or expansions to the served building or facility.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
