Do you need a building permit in Klickitat County, Washington?

Unincorporated Klickitat County requires county-issued building permits and inspections for dwellings and most buildings before use or occupancy.1 The Building Department reviews plans and documents under county code and the Washington State Building Codes, including fire-life-safety and design criteria.13 Required inspections depend on the project, and the county provides the inspection list with the permit.14 Footing or foundation rebar must be inspected before concrete is poured when that work applies.14

An owner working on their own property may qualify for Washington's contractor-registration exemption when the work is not done for sale, demolition or lease.15 That exemption concerns contractor registration, not building, electrical, plumbing, septic or other permits.10 At project completion, a certificate of occupancy can be granted after all applicable departments approve the work, we could not confirm that every project requires one.16

Who is the Klickitat County building department, and how do you reach it?

The Klickitat County Building Department is the permit and inspection contact for county-issued building approvals; call 509-773-3706 or email buildingdept@klickitatcounty.gov.117 The office is at 115 W. Court St., Rm 301, Goldendale, WA 98620.17 Inspection requests must be called in at least 1 day ahead.17

Applications may be routed to Environmental Health for water and sewage approval, Planning for zoning and setbacks, and Public Works for a county-road approach.18 The Building Department invoices the balance after required departmental approvals, and fees must be paid before permit issuance.18 Processing time varies with project scope, required approvals and workload.19 Building fees depend on valuation and service type; some inspections and services cost $95 per hour or the jurisdiction’s total hourly cost if higher, with minimum charges.20

Inside White Salmon, use the city building-permit authority; Bingen contracts with Skamania County for building and inspection services.2122 On-site septic review stays with Klickitat County Environmental Health.423

Does Klickitat County have zoning?

Unincorporated Klickitat County has county zoning, and its Interactive Mapping Program shows parcel zoning.224 White Salmon and Bingen administer their own zoning inside city limits; county district standards below apply to unincorporated land.25263 On-site septic review remains with Klickitat County Environmental Health.4

Lot size, setbacks and allowed uses vary by district.6 Rural Residential requires 20-foot front and rear yards and 5-foot side yards, measured from property lines and right-of-way edges.27 Rural Center requires 15-foot front and rear yards and 5-foot side yards; without community water and sewer, Planning and the health officer determine the necessary lot area.28 Rural-zoned buildings generally sit 50 feet from property lines, increasing to 100 feet for new residences beside specified commercial agricultural, timber or mineral-extraction land.29 Residential requires a 20-foot front yard and 5-foot side and rear yards; Suburban Residential requires 20-foot front and rear yards and 5-foot side yards.3031 Open Space requires a 30-foot front yard, 25-foot side yards and a 50-foot rear yard.32 Ask County Planning to confirm the parcel’s district before drawing a site plan.33

How do septic permits work in Klickitat County?

Klickitat County Health Department Environmental Health handles on-site septic permitting, review and inspection; call the Goldendale office at 509-773-4565.434 For a new build using on-site sewage, complete the system design and obtain the septic permit before the building permit.7

A resident homeowner may design a simple gravity system when the site evaluation allows it; other systems require a licensed designer or engineer.35 A homeowner installing a simple gravity system must pass the county certification exam, or a licensed installer is required.5 After installation, the owner or installer must request a final inspection, and a scaled as-built drawing must be submitted before occupancy.36 Environmental Health may require private-water availability verification for wells, springs or cisterns, water testing, or verification of public-water and sewer connections, depending on the project and location.11 Rural sewer is generally unavailable, so an approved on-site septic system or other treatment process is needed where sewer does not serve the property.37 Only about 17.1% of mapped soils are rated without severe limitations for a conventional septic drain field, so make septic feasibility an early purchase contingency.38

Can you live in an RV or tiny home on your land in Klickitat County?

We could not confirm permission for permanent RV living on an ordinary private parcel in Klickitat County; ask County Planning about the proposed use.33 The Rural Resource Land district’s conditional-use provision for RV parks and campgrounds does not authorize individual RV occupancy elsewhere.8

Klickitat County allows temporary placement of a manufactured home, RV, park trailer or tiny home only after issuance of a new-construction residential building permit.9 The temporary permit lasts 1 year, with extensions for justifiable cause; invalidation of the building permit also invalidates the temporary permit.9 Approval of the new home’s occupancy ends the temporary permit, requiring removal or compliance with the county’s manufactured-home special provisions.9 Tiny homes on wheels are treated as RVs, and permanent placement requires a HUD insignia.9 Manufactured-home final approval also requires installation inspections, state Labor and Industries electrical verification, and planning, health, access and setback compliance.39

An ADU in unincorporated Klickitat County requires an administrative conditional use where a single-family home is permitted outright; the owner must occupy either dwelling at least 6 months annually, and a detached ADU must be within 200 feet of the principal home.40 Neither dwelling may be a short-term vacation rental under that ADU rule.41

Building a home in Klickitat County: what are the steps?

  1. Confirm whether the parcel is inside a city; outside city limits, ask County Planning to identify the zoning district, lot-size standard, setbacks and allowed use.36
  2. Verify the required private-water or public-water documentation and whether public sewer is available.11
  3. For on-site sewage, complete the design and obtain the septic permit before the building permit.7
  4. If access comes from a county road, obtain road-approach approval through Public Works; a state-highway connection instead needs written state permission.4243
  5. Submit the building application and plans; the county routes the application for required departmental approvals and calculates fees during review.18
  6. Pay the invoice, receive the permit package and follow its project-specific inspection list.1814
  7. Request the final septic inspection, submit the scaled as-built drawing before occupancy and obtain all applicable final approvals.3616

What should you check before buying land in Klickitat County?

Confirm jurisdiction and zoning first because County Planning handles land outside city limits, while incorporated cities use their own planning departments.3 Check the parcel's mapped district, lot standard, setbacks and utilities before relying on a building envelope.246 Unincorporated Klickitat County regulates land divisions under its subdivision ordinance; a subdivision creates 5 or more divisions, while a short subdivision creates 4 or fewer.44 Start boundary adjustments and land divisions with Planning; the Assessor is the final step, and the year’s property taxes must be paid in full before the process begins.45

Make water and septic feasibility purchase contingencies because documentation requirements depend on the water and sewer setup.11 Only about 17.1% of mapped soils avoid severe conventional-drain-field limits.38 Check flood maps before selecting a building pad because development in a Washington floodplain requires a local floodplain development permit.46 Confirm legal road access as well: county-road approaches require county approval, while state-highway approaches require written permission from the Washington Department of Transportation.4243 The effective property-tax rate is about 0.6%, with a median annual bill around $2,401.4748

Watch-outs

  • An owner-builder exemption from contractor registration does not remove Klickitat County building permits or separately regulated trade permits.10
  • A septic design and permit must come before the building permit when a project relies on an on-site sewage system.7
  • A driveway from a county road needs county road-approach approval; a connection within a state-highway right-of-way needs written state permission instead.4243
  • An RV park or campground is only a conditional use in the Rural Resource Land district, and that rule does not authorize long-term occupancy of an individual RV on an ordinary parcel.8
