Hood River County, Oregon requires building permits in most cases for new construction, additions, remodels and repairs1. County Planning sets zoning in unincorporated areas, while the cities of Hood River and Cascade Locks administer their own local rules2. Septic permits for systems under 2,500 gallons a day come from Hood River County Environmental Health, not the building department3.
Do you need a building permit in Hood River County, Oregon?
Yes.
Yes. Hood River County says permits are needed in most cases for new construction, additions, remodels and repair work, including residential projects1. Oregon's residential rules also require a building permit to construct, enlarge, alter, repair or move a residential building or structure, although listed exemptions apply and exempt work can still need trade permits10.
Permitted construction must remain accessible for inspections until the building official approves it, and work cannot advance beyond required inspection points without approval11. A new residential dwelling or townhouse also needs a certificate of occupancy before occupancy unless the building official issues a temporary certificate11. Qualifying agricultural structures may receive a structural-code exemption, but electrical, plumbing and mechanical permits can still apply5.
Oregon also has an owner-builder path for a single-family home built entirely by the owner, but it relaxes only structural rules on ceiling heights, room sizes and temperature, and an owner can use it only once in five years5.
Who issues building permits in Hood River County?
The Hood River County Building Department processes applications, issues permits and conducts inspections.
The Hood River County Building Department processes applications, issues permits and conducts inspections1. Responsibility changes with location: Hood River County oversees the full program generally and in Cascade Locks, while the City of Hood River handles structural and mechanical work inside that city and the county handles plumbing and electrical work there1.
For county service, contact the Building Department at the phone, email or address listed above, or use Oregon ePermitting1. Building fees vary by work type and valuation method12. Public Works separately publishes a county fee schedule for driveway, road-approach, right-of-way and development reviews; the schedule can change annually or twice yearly13. Oregon's owner-builder exemption is narrow: qualifying owners doing the structural work themselves or with unpaid friends and relatives still need a building permit, and the exemption covers only ceiling heights, room sizes and specified temperature requirements5.
Does Hood River County have zoning?
Yes.
Yes. Hood River County Planning applies county zoning and land-use review throughout unincorporated Hood River County, outside Hood River and Cascade Locks4. The county publishes district-specific articles for farm, forest, residential, commercial, industrial and overlay districts, so the mapped zone controls uses, lot standards and setbacks14.
In the R-1 Zone, a sewer-served lot generally needs at least 7,500 square feet, but R-1 land generally has a 2-acre minimum unless it is within an established urban or rural unincorporated community; lots without sewer must meet County Health Department requirements for water and sewage disposal15. For new Rural Residential lots, the zoning map sets the minimum, while RR 1/2 and RR1 land generally has a 2-acre minimum outside those established communities16. Rural Residential structures have district-specific setbacks: the front minimum varies by street and right-of-way measurement, with 20-foot rear and 10-foot interior-side minimums16. Ask County Planning to verify the parcel's mapped zone, community status, overlays and exact building envelope4.
In the Exclusive Farm Use (EFU) zone, new dwellings, buildings and land divisions face an 80-acre minimum, and the forest zones F-1 and F-2 carry the same 80-acre minimum17,18. In the R-1 zone, buildings may cover no more than 30 percent of the lot and may not exceed 35 feet19. Short-term rentals are allowed only by district: one per parcel, with a revocable permit that renews every 2 years, and they are prohibited in several zones including F-2, M-1 and M-220.
How do septic permits work in Hood River County?
Hood River County Environmental Health conducts site evaluations, issues permits and performs inspections for onsite systems producing less than 2,500 gallons of wastewater per day under a contract with Oregon DEQ.
Hood River County Environmental Health conducts site evaluations, issues permits and performs inspections for onsite systems producing less than 2,500 gallons of wastewater per day under a contract with Oregon DEQ3. A septic permit is required before constructing, altering or repairing a system or any part of one; larger systems or waste stronger than residential wastewater go directly to the DEQ water-quality program3.
Site feasibility deserves early attention because only 8.8% of mapped county soils are rated without severe limits for a conventional septic drain field21. That statistic does not decide a parcel's permit, but it makes the county site evaluation an important early contingency. Completed permitted work must be reported for inspection, and the agency has 7 days after official notice to inspect unless it waives inspection and allows earlier backfilling22. Contact Environmental Health before settling on a house site or septic layout3.
A composting toilet does not remove the septic requirement: plumbing fixtures still connect to an approved septic system, and a building inside a sewer district still needs a sewer connection23.
Can you live in an RV or tiny home in Hood River County?
Oregon allows a camping vehicle on private land with the owner's consent only when the parcel has adequate approved water and sewage facilities and the occupant complies with applicable sanitation, water, plumbing, electrical and sewerage standards.
Oregon allows a camping vehicle on private land with the owner's consent only when the parcel has adequate approved water and sewage facilities and the occupant complies with applicable sanitation, water, plumbing, electrical and sewerage standards24. Hood River County zoning still controls the parcel and proposed use, so ask County Planning before treating that statewide rule as approval for long-term occupancy4.
Residential RV occupancy is expressly protected in qualifying parks with lawful utility connections and temporarily beside a disaster-damaged home, subject to the stated end points and local conditions6. At Toll Bridge Park, campground stays are limited to 7 consecutive days per site and 30 days in one season per park; that recreational rule does not authorize living in an RV on private land25. Current dispersed camping in non-day-use County Forest areas is likewise recreational26. A tiny house on a trailer has a narrow hardship route in the Columbia River Gorge National Scenic Area, requiring a permit, qualifying family care need, suitable sewage disposal and timely removal when authorization ends7. We could not confirm a broader tiny-home occupancy rule; ask County Planning about the parcel and dwelling design4. Oregon lets a county allow one rented RV on a rural lot that has an owner-occupied home as the owner's primary residence, but whether Hood River County has chosen to allow it could not be confirmed; ask County Planning4,27.
Building a home in Hood River County: what are the steps?
Ask the correct planning authority to confirm zoning, setbacks and required agency signoffs for the parcel's jurisdiction.
- Ask the correct planning authority to confirm zoning, setbacks and required agency signoffs for the parcel's jurisdiction2.
- Have Environmental Health evaluate the site and issue the septic permit if the home will use an onsite system within the county program3.
- Resolve the water source; a landowner personally constructing, altering or abandoning a supply well needs the state permit, fee and financial security before beginning work8.
- Prepare an accurate site plan and obtain required service-district signatures before submitting the building application28.
- For a new driveway on a county road, submit the right-of-way application to Public Works; access from a state highway instead requires an ODOT permit29.
- Submit the structural application to the correct building authority, then obtain any needed mechanical, electrical and plumbing permits28.
- Call for inspections at each required point and obtain the certificate of occupancy before moving into a new dwelling unless a temporary certificate has been issued11.
What should you check before buying land in Hood River County?
Confirm the parcel's jurisdiction, zone, overlays and allowed dwelling type before relying on a listing description.
Confirm the parcel's jurisdiction, zone, overlays and allowed dwelling type before relying on a listing description2,14. A floodplain development application must include either a qualified biologist's mitigation assessment or a statement that the work is exempt from that assessment9.
Make septic feasibility a purchase contingency: only 8.8% of mapped soils avoid a severe conventional-drain-field limitation, and the county conducts site evaluations for systems in its program3,21. Confirm the water source early; a landowner who intends to drill personally faces a state permit, fee and financial-security process8. Verify legal access because a new connection or approach in a county-road right-of-way needs a permit29. The countywide effective property-tax rate is about 0.6%, and the median annual property-tax bill is $3,359; verify the parcel's actual account21. We could not confirm a countywide public-water or sewer connection rule, so ask the planning authority and applicable service district.
Watch-outs
- Inside the City of Hood River, the city handles structural and mechanical codes while Hood River County handles plumbing and electrical codes; Cascade Locks has a different administrative arrangement1.
- A county-road driveway needs a county permit, while access from a state highway requires an ODOT permit29.
- Floodplain development applications in mapped areas have an added mitigation-assessment or exemption-statement requirement9.
- Toll Bridge Park limits campground stays to 7 consecutive days per site and 30 days per season per park; county-park and County Forest camping rules do not authorize residential RV use on private land25,26.
- A tiny house on a trailer has a specific hardship path in the Columbia River Gorge National Scenic Area, but we could not confirm a broader tiny-home occupancy rule7.
