Do you need a building permit in Bingen, WA?

Bingen requires a construction permit for new construction and generally requires a building permit when a structure is built, enlarged, altered, repaired, moved or demolished.1 Depending on the work, Bingen applicants may also need mechanical, plumbing, electrical or grading approvals.8

A detached residential storage shed or similar accessory structure may be exempt if its floor area does not exceed 300 square feet and it contains no plumbing.1 Bingen also lists exemptions for fences no higher than 6 feet and retaining walls no higher than 4 feet, measured from the bottom of the footing to the top of the wall.1 A building-permit exemption still leaves building-code and other approval requirements in place.9

Who handles building permits and planning questions in Bingen?

The City of Bingen contracts with Skamania County for building and inspection services; the city directs building-permit questions to the building email and planning questions to the permit-center email listed above.9 For zoning setbacks or critical-area buffers, Bingen directs applicants to the Community Development Department and asks callers to speak with a planner.7

Bingen has adopted building codes with Washington amendments, including the International Residential Code and International Building Code.10 Send the building contact a description of the proposed construction before deciding that a project falls within an exemption, because Bingen states that exemption from a building permit does not remove other permitting requirements.9

Does Bingen have zoning, lot-coverage limits and setbacks?

Bingen administers its own zoning map and directs applicants to the city municipal code for district setbacks and density requirements.2 In Bingen’s R Residential District, maximum building coverage is 50% of the lot; in the MF Multiple-Family Residential District, maximum lot coverage is also 50%.56 Those coverage limits describe the named districts, rather than a citywide minimum home size.56

Bingen requires zoning setbacks and applicable critical-area buffers even for projects exempt from building permits.7 Bingen also regulates subdivisions, short plats, boundary-line adjustments and binding site plans, so ask the planning contact about the proposed land division before relying on a parcel split to make a project work.117

How do septic permits and sewer connections work in Bingen?

Klickitat County Environmental Health administers on-site sewage systems inside Bingen, while Bingen separately regulates public sewer connections.3 When public sewer becomes available under Bingen’s code, a property using private sewage disposal must connect and abandon the private system unless the superintendent permits otherwise.4 Ask about sewer availability before budgeting for a new septic system.4

For a Bingen property eligible to use septic, the county’s site and soil evaluation guides system design, and an approved design precedes the septic permit.12 A septic permit is required before the building permit, and the gravity-system application lists a $500 installation fee and permit validity of 1 year.13 Completed installations require a final inspection and a scaled as-built record drawing before occupancy.14

Can you live in an RV or tiny home in Bingen?

We could not confirm a complete rule allowing permanent RV living, private-land camping or tiny-home occupancy in Bingen; ask the planning contact about the exact parcel, zoning district and proposed housing arrangement.7 We also could not confirm Bingen’s minimum primary-dwelling floor area or a complete manufactured-home occupancy rule; request those answers before buying a structure for the site.7

Bingen’s exemption for a small detached accessory structure is a building-permit exemption for the stated accessory uses, rather than an established permission to occupy that structure as a home.1 Zoning setbacks and critical-area buffers remain applicable to exempt construction, making the planning review relevant even when the structure does not need a building permit.7

What are the steps for building a home in Bingen?

  1. Identify the Bingen zoning district on the city map and discuss the intended use, setbacks and applicable critical-area buffers with the planning contact.27
  2. Establish wastewater disposal: ask about city sewer availability, or arrange county site evaluation, design review and a septic permit where an on-site system is eligible.41312
  3. Contact Bingen’s contracted building service about the construction permit and any mechanical, plumbing, electrical or grading approvals needed for the work.8
  4. Arrange required building inspections through the contracted service; for septic, obtain final inspection and submit the as-built drawing before occupancy.914

Watch-outs

  • Bingen building services come through Skamania County, while on-site septic administration stays with Klickitat County Environmental Health.83
  • Bingen public sewer availability can require connection and abandonment of an existing private sewage system.4
  • We could not confirm a general Bingen owner-builder exemption or certificate-of-occupancy procedure; ask the building contact before planning self-construction or a move-in date.9
