Unincorporated Lincoln County, Oregon requires a building permit for any new construction and for any addition, alteration or repair to an existing building, plus separate permits for wiring, plumbing and mechanical work1. The county Planning Division sets zoning on land outside the cities, and every building application starts with its zoning-clearance review23. In the unincorporated county, septic permits come from the county's Onsite Waste Management Division, which acts as Oregon DEQ's contract agent4.

Do you need a building permit in Lincoln County, Oregon?
Unincorporated Lincoln County, Oregon requires a building permit for any new construction and for any addition, alteration or repair to an existing building115. Wiring, plumbing and mechanical installations such as furnaces and wood stoves each need their own permit before the work is performed15. The Building Division issues these permits and performs inspections for all of unincorporated Lincoln County plus Depoe Bay, Siletz, Toledo, Waldport and Yachats16. Every application first goes through Planning Division zoning clearance3. A qualifying agricultural building on designated farm or forest land may be exempt from the structural code, but the exemption does not cover a dwelling, and electrical, plumbing and mechanical work still needs permits17. Oregon's owner-built exemptions remain subject to permit, fee, plan-check and inspection requirements; separate septic and land-use approvals also still apply1819.
Who is the Lincoln County Building Division and how do you reach them?
The Lincoln County Building Division handles building permits and inspections for unincorporated Lincoln County and for Depoe Bay, Siletz, Toledo, Waldport and Yachats16. The division asks that you call at 541-265-4192 to speak with an inspector or the building official about code questions between 7 am and 8 am Monday through Friday, or email general questions to lincolncountybldgdiv@co.lincoln.or.us16. The Planning & Development Department, which runs the zoning-clearance review that comes before any building permit, is at 210 SW 2nd Street, Newport, Oregon 97365 and shares the same 541-265-4192 phone line20. Once work is underway, permit holders must call for an inspection at each stage of the project, and a manufactured-home permit specifically requires footing, blocking and final inspections plus any separate electrical, plumbing or mechanical inspections1621. Development inside Depoe Bay, Waldport, Yachats, Toledo or Siletz itself, rather than the surrounding unincorporated county, starts with that city's own land-use approval first3.
Does Lincoln County have zoning?
Lincoln County zoning applies to land under county jurisdiction outside incorporated cities and is administered by the Planning Division under Lincoln County Code Chapter 156. Contact a planner for the zoning on a specific parcel rather than relying only on a general map22. In the RR-5 zone, a dwelling lot must contain at least 5 acres and a structure may not exceed 30 feet, subject to code exceptions1323. In the R-1 zone, buildings may cover no more than 30% of the lot and may not exceed 30 feet2425. R-1 lot size depends on services: 6,000 square feet for a single-family dwelling only where both public or community water and sewage disposal serve a lot inside a Rural Community Boundary or Urban Growth Boundary, and 2 acres per dwelling unit where the lot lacks community sewage disposal or water or lies outside a Rural Community Boundary26. The R-1 front yard is at least 20 feet27. An R-1-A manufactured dwelling must be multi-wide, stand on a permanently enclosed foundation and contain at least 1,000 square feet28. Accessory dwelling units are allowed only inside an urban growth boundary and generally are capped at 800 square feet or 75% of the primary home's floor area, whichever is smaller12. These district-specific rules make the parcel's exact zone decisive before you plan a split, small home or accessory dwelling20. Subdivisions, partitions and replats in the unincorporated area need Lincoln County approval, each new lot needs at least 25 feet of road frontage, and no building permit issues for a subdivision lot until the plat is recorded29.
How do septic permits work in Lincoln County?
In unincorporated Lincoln County, septic systems go through the county's Onsite Waste Management Division, which administers siting, installation and repair as Oregon DEQ's contract agent under an intergovernmental agreement7. Oregon DEQ directly permits septic systems in only three counties, Curry, Jackson and Josephine; everywhere else, including Lincoln County, DEQ contracts the work out to the local jurisdiction, which matches how Lincoln County's own site describes the Onsite Waste Management Division304. The county's septic procedures are described for the unincorporated area, so a parcel inside a city or a sewer district may follow that city's or district's own connection process31. The first step is a site evaluation, an assessment of a site's suitability for on-site sewage disposal based on soil, hydrology and topography, and a favorable evaluation sets the approved installation area and the system specifications32. Only about 2.6% of Lincoln County's soils carry no severe limitation for a conventional septic drain field under the USDA soil survey, so budget for a site evaluation to turn up limits that call for an engineered or alternative system on most parcels33. A construction installation permit is required before installing a system, repairs and alterations need their own permits, and the permit is valid for 1 year after issuance31. One or more inspections happen during installation, and a final inspection leads to a Certificate of Satisfactory Completion34. A composting toilet needs its own permit and does not remove the need for an approved septic system, because household water remains; material removed from one must be buried under 12 inches of soil35. Reach the Onsite Waste Management Division at 541-265-4192; its environmental health specialists are available in the mornings, roughly 8 a.m. to 9 a.m., before they leave for inspections32.
Can you live in an RV, manufactured home or tiny home on your land in Lincoln County?
An RV on an individual lot in unincorporated Lincoln County requires conditional-use authorization where the parcel's zoning allows it, approved water and sewage disposal, and renewal no later than 5 years; the county may also require a 6-foot sight-obscuring fence10. In R-1, RR-2, RR-5 and RR-10 zones, a tiny home, RV or other approved temporary housing may be occupied during construction of a permitted single-family home for no more than 1 year11. That temporary rule does not establish standalone year-round tiny-home occupancy, so ask the Planning Division before buying for that use1120. A commercial RV park is a different use: where zoning lists one as conditional, the park needs conditional-use approval and must meet state and county design standards36. A temporary hardship manufactured dwelling may accompany an existing home in an A-C or T-C zone, with yearly medical confirmation and removal or demolition within 3 months after the hardship ends37. Approved mobile homes on individual lots must meet Oregon setup standards, be skirted and may face added compatibility conditions37.
Building a home in Lincoln County: the steps, in order
- Contact the Planning Division for the required zoning-clearance review; every building application starts there before Oregon E-Permitting320.
- Submit your application materials as one complete packet; applying by email gets you a fee link for a $250 zoning-clearance deposit38.
- If anything is missing, you have 30 days from notice to submit the corrected or missing items, or the application is withdrawn3.
- Apply for your building permit through Oregon E-Permitting once zoning clearance is complete339.
- If you will live in the home and act as your own contractor, sign the Property Owner Statement Regarding Construction Responsibilities before the Building Division issues the permit9.
- For sewage disposal, contact the serving sewer district or obtain county approval to install or connect to an on-site system40.
- Get a $100 road-approach permit from Lincoln County Public Works before adding or changing a driveway access within the county right-of-way4142.
- Call the Building Division for required inspections; after all structural-permit inspections are complete and fees are paid, a certificate of occupancy can be issued when that workflow applies162143.
What to check before you buy land in Lincoln County
Lincoln County gets about 91 inches of rain a year and spends only about 10.4% of years in severe drought, so water supply is less of a worry here than in most rural counties on this site, though a well still needs its own permit4445. A landowner-constructed well requires a $550 permit fee and a $10,000 bond unless you are a licensed and bonded well constructor, and the permit itself expires 6 months after issuance46. Single or group domestic groundwater use up to 15,000 gallons a day is exempt from a separate water-use permit, though the well-construction rules above still apply47. With 93.2% of the county wooded, 57.9% in federal ownership and only 16% of the land at 15% slope or less, expect fewer easy building sites and more clearing, grading or access work than in flatter counties on this site484950. Confirm your parcel is not in a Special Flood Hazard Area with the Planning Division's floodplain program before you buy20. A typical Lincoln County property carries an effective property tax rate near 0.8%, a median tax bill around $3,241 a year, and a typical home insurance premium near $1,177 a year, though your own parcel's numbers depend on its assessed value and coverage515253.
Watch-outs
- Lincoln County's Building Division now requires a demolition permit as of January 1, 2026 and collects plan-review fees at documentation submittal as of July 1, 2026; confirm current fees and requirements with the Building Division before you plan a project5416.
- Camping in a Lincoln County park or on other county property is allowed only in designated public campgrounds and is generally limited to 10 days in a 14-day period unless the Parks Director approves more time55.
- Lincoln County allows an approved tiny home as temporary housing during construction in specified residential zones, but standalone year-round occupancy is not established; call the Planning Division before buying land for that plan1120.
- Short-term rentals in unincorporated Lincoln County need a license from the Lincoln County Sheriff's Office, and the county caps how many licenses it issues; ask before you buy a home counting on rental income56.
