Do you need a building permit in Cle Elum, WA?

Cle Elum requires a building permit for residential, commercial, fire-safety, mechanical, plumbing and other projects unless specifically exempted.1 The Cle Elum Building Department reviews building permit applications and handles inspections for the city.2 Electrical permits come separately from Washington’s Department of Labor & Industries.1

Cle Elum uses the adopted building codes listed by the city, including the International Residential Code and Washington State Energy Code.9 A qualifying owner may be exempt from the contractor and city business-license submission requirement, but that exemption does not remove the city’s building-permit requirement.81 Ask the Building Department to confirm the exemption for your proposed work before starting.2

Who is the Cle Elum building department, and how do you apply?

Contact the Cle Elum Building Department at (509) 674-2262, or visit 119 West First Street Cle Elum, WA 98922, for city building-permit review and inspection questions.2 Cle Elum’s application requires a site plan and construction documents, with professional stamps where state law requires them.1

Cle Elum requires a deposit at application, and the permit number is issued once the deposit is received.10 Electronic applications, site plans, construction drawings and other required documents must be PDF files, with each document submitted as a separate file.10 Ask the Building Department for the project’s current fee calculation and inspection sequence when preparing the application.2

Does Cle Elum have zoning, lot-size rules and setbacks?

Cle Elum has city zoning, and the Planning Department maintains the official zoning, land-use and critical-areas maps.3 City Planning implements the comprehensive plan and adopted development regulations; the same department administers design review, grading and excavation permits, and environmental review for critical areas, shorelines and floodplains.5

Ask Cle Elum Planning to identify the parcel’s zoning district and confirm the proposed dwelling, lot size, setbacks, lot coverage and height before finalizing a site plan.5 We could not confirm Cle Elum’s district-specific dimensional standards; request those standards from city Planning rather than using the county’s zoning tables for a city parcel.5

How do septic permits work inside Cle Elum?

For a Cle Elum property using on-site sewage, Kittitas County Public Health is the septic permitting authority.4 A septic installation permit requires a parcel site evaluation by a county Environmental Health Specialist, followed by a system design from a licensed designer; homeowners may prepare their own design after a required pre-design meeting.6

County approval of the septic design is separate from issuance of the installation permit: the installer or homeowner must request that permit when ready to install.4 The completed system needs inspection before final approval, and the drain field must remain uncovered until final inspection.4 Contact the county’s on-site sewage program at 509-962-7515 before committing to a septic-dependent purchase or design.4

Can you live in an RV or tiny home in Cle Elum?

We could not confirm whether Cle Elum allows residential RV occupancy or temporary camping on a private lot; ask city Planning about the specific address, duration and proposed use.5 Cle Elum’s Planning Department administers city development regulations, so city Planning is the place to resolve the land-use question before buying an RV or ordering a small dwelling.5

Washington tiny houses must meet the state building code, and local building-department requirements apply to their foundation, installation and location.7 A wheeled unit that does not qualify as a code-compliant tiny house may instead be an RV or park model.7 Confirm both the unit’s classification with Cle Elum Building and the proposed residential use with city Planning.25

Building a home in Cle Elum: what comes first?

Start with Cle Elum Planning: request the parcel’s official zoning and critical-areas information, and discuss any shoreline or floodplain review before fixing the home’s footprint.5 Then prepare the city building application, site plan and construction documents, and arrange the required application deposit.1 Submit electronic documents as separate PDF files.10

For a septic proposal, arrange the county site evaluation and design before seeking the installation permit.6 Obtain electrical permits through Washington Labor & Industries and ask Cle Elum Building to establish the construction inspection sequence.12 For a parcel outside city limits, use the Kittitas County guide for the county’s building-permit and zoning requirements for unincorporated land.1112

Watch-outs

  • We could not confirm Cle Elum’s water and sewer connection requirements; ask city Planning to resolve utility servicing before relying on a septic or private-well proposal.5
  • Cle Elum Planning administers floodplain and shoreline environmental permitting; bring the parcel location to the city before committing to a building footprint.5
  • A Cle Elum owner-builder license exemption does not waive the building permit.81
