Does White Salmon have zoning, lot-size rules and setbacks?

White Salmon has city zoning, and the Planning Department reviews building applications for conformity with city zoning rules.52 In the R1 district, the minimum lot area is 3,000 square feet for each single-family structure; in RL, the minimum lot area is 11,000 square feet.1011

White Salmon's R1 setbacks are 12 feet front, 5 feet side and 10 feet rear, with an allowance for porches, stoops or transitional structures to encroach into the front-yard frontage zone.12 RL setbacks are 20 feet front, 5 feet side and 15 feet rear.13 Ask White Salmon Planning to confirm the parcel's district before choosing a house footprint.2

Do you need a building permit in White Salmon, and who issues it?

White Salmon's Online Permit Center says building permits are required for new construction and alterations or additions to existing buildings.1 Use the city portal to apply, check application status, pay online and request inspections.1 White Salmon contracts with Hood River County's building officials; the Oregon office is the city's identified building contact, rather than the Klickitat County building counter.1

White Salmon Planning separately reviews zoning conformity and handles land-use applications.2 Ask Planning whether a change of use, land-use approval or critical-areas review is needed for the project.1 Washington's state building code applies in cities as well as counties.14

How do septic permits and sewer connections work inside White Salmon?

White Salmon prohibits constructing or maintaining privies, septic tanks, cesspools and other sewage-disposal facilities except as provided elsewhere in the city's sewer chapter.4 A White Salmon property using private sewage disposal must connect directly when public sewer becomes available under the city's availability provisions; abandonment and filling of the old facilities is required unless the public works director or representative permits otherwise.15

Ask the city about sewer availability and any applicable exception before commissioning a septic design.415 Where an on-site system is permissible, Klickitat County Environmental Health's process requires a design before the septic permit and a final inspection after installation.3 County septic approval does not itself establish an exception to White Salmon's sewer restrictions.34

Can you live in an RV or tiny home in White Salmon?

White Salmon prohibits rooms in RVs or travel trailers from being used for transient rentals, and the same restriction covers tents and other temporary shelters.616 We could not confirm whether White Salmon permits personal RV occupancy on a residential lot or RV living while building; ask White Salmon Planning about the proposed use and duration.62

White Salmon allows qualifying tiny houses in the mobile/manufactured-home residential park district, subject to the district's definitions and construction requirements.7 The qualifying tiny-house definition caps interior habitable area at 400 square feet, excluding sleeping lofts.7 Separately, R1 primary single-family dwellings and RL single-family dwellings have a 400-square-foot minimum, with specified excluded spaces; these district rules are not blanket permission to park a tiny house anywhere in White Salmon.897

Building a home in White Salmon: what are the steps, in order?

Start with White Salmon Planning: request the parcel's zoning district and ask whether the project needs land-use approval or critical-areas review.21 Next, resolve sewer service or the city's exception for private sewage disposal before arranging county septic review.4153

Prepare the building application for White Salmon's Online Permit Center, then use the same portal to track progress and request inspections with the city's contracted building officials.1 If the project includes a regulated driveway connection to a city street, obtain the required city construction permit before beginning that activity unless an express exemption applies.17 For residential flood-elevation elements, White Salmon requires foundation-elevation verification before footing-inspection approval and lowest-floor verification before framing-inspection approval.18

What should you check before buying land in White Salmon?

Ask White Salmon Planning to review the proposed use against the parcel's zoning, including any land division: short plats must conform to city zoning lot sizes and dimensions.219 White Salmon's R1 district limits lot coverage to 75% and building height to 28 feet, so minimum lot area alone does not settle how much home can fit.2021

Ask city Planning for the current parking requirements: the city's application page warns that an adopted parking-reform ordinance has errors in the online code.22 For land outside White Salmon city limits, use the Klickitat County guide for the county building-permit and zoning answers.2324 We could not confirm a city-specific private-well approval rule or certificate-of-occupancy requirement; ask the city building and planning offices before relying on either for a purchase or move-in schedule.12

Watch-outs

  • White Salmon's RV transient-rental restriction does not answer personal RV living while building; ask city Planning before planning that occupancy.62
  • A county septic permit does not waive White Salmon's restrictions on private sewage disposal or the city's sewer-connection requirement.3415
  • White Salmon's permit page flags errors in the online parking rules; get the current requirements from city Planning.22

We looked and could not find an official answer yet. Silence is not permission; ask White Salmon or Klickitat County directly.

  • Owner-builder exemption — Owner-built residential construction inside White Salmon city limits.
  • Certificate of occupancy — Construction and occupancy inside White Salmon city limits.
  • Septic permit — On-site sewage systems inside White Salmon city limits.
  • Septic inspection — On-site sewage systems inside White Salmon city limits.

Unanswered questions are usually a sign that White Salmon publishes no rule on the point, not that none exists. Klickitat County’s page lists the county offices to call.
