Yamhill County, in the Willamette Valley wine country, has about 110,000 residents and is a county of vineyards and farmland centred on McMinnville. Its Planning and Development Department administers land use and building for unincorporated areas, issues building permits in Amity, Carlton, Sheridan, Willamina and Yamhill, and issues electrical permits in McMinnville, Newberg and the county’s other cities too; McMinnville, Newberg, Dundee, Dayton and Lafayette issue their own building permits.
This guide covers Planning and Development, the uniform statewide code, the wine-country farmland and land-use context, and where city-limit work goes instead.
This guide covers unincorporated Yamhill County and the cities the county permits: Amity, Carlton, Sheridan, Willamina and Yamhill. McMinnville, Newberg, Dundee, Dayton and Lafayette issue their own building permits, but their electrical permits come from the county.
Yamhill County is prime wine-country farmland, so exclusive farm-use zoning and the rules around wineries, tasting rooms and farm dwellings shape a project before the building code. The Planning and Development Department administers the state code and land use for unincorporated areas; confirm the zoning and any winery or farm-use limits for the parcel before design.

The Oregon Residential Specialty Code (ORSC) governs one- and two-family dwellings and townhouses and their accessory structures; the Oregon Structural Specialty Code (OSSC) governs commercial buildings, apartments of three or more units and everything outside the residential scope. Alongside them sit the mechanical, plumbing, electrical and energy specialty codes, and the Oregon Fire Code is adopted by the State Fire Marshal. In Yamhill County, Planning and Development administers the state code and land use for unincorporated areas, with farm-use zoning and winery rules settled ahead of the building permit.
Oregon’s building code and its exemptions are the same in Yamhill County as everywhere in the state, and an exemption from the building permit is not an exemption from zoning, land use or a trade permit. Site snow, wind and seismic values come from the state’s Oregon Design Criteria Hub. How Oregon’s statewide code works
Who handles permitting in Yamhill County?

| Authority | Yamhill County Planning and Development Department |
| Seat | McMinnville |
| Serves | Unincorporated county, Amity, Carlton, Sheridan, Willamina and Yamhill |

The Planning and Development Department administers land use and the state building code for the unincorporated county. Because the county is prime wine-country farmland, exclusive farm-use zoning and the specific rules for wineries, tasting rooms and farm dwellings often settle what can be built before the building permit. Confirm the zoning and any winery or farm-use limits from the parcel first.

In 2025, building permits issued in unincorporated Yamhill County authorized 100 new privately owned housing units, 98 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.
Permit types
Residential permits
Unincorporated residential work is shaped by farm-use zoning and rural siting. Re-roofs beyond the exempt scope, solar and EV chargers need permits, seismic detailing applies broadly, and every contractor needs a current CCB licence, apart from casual work under $1,000 and owners working on their own property.
Commercial permits
Commercial work runs from wineries and production facilities to farm-based hospitality, with the county handling unincorporated development under farm-use and winery rules. Contractors on it need a CCB licence, and electrical and plumbing work is generally done by state-licensed trades.
Contractors need a current Construction Contractors Board licence with the right endorsement for a job of any size; the exceptions are casual work under $1,000 by someone who does not advertise as a contractor, and owners working on their own property who are not building to sell.

Oregon fixes the method rather than the price: new construction is valued with the ICC building valuation data under OAR 918-050-0100, Yamhill County applies its own schedule, and a 12 percent state surcharge is added to every permit fee. How Oregon permit fees are set

Electricians and plumbers are licensed by the state, though an owner may do electrical work on their own home and plumbing work that is not for hire. An electrical permit is needed for new or altered wiring; like-for-like repairs of outlets, switches and fixtures, and bulb, fuse and small-appliance swaps, are exempt.

McMinnville, Newberg and Dundee issue their own building permits, but electrical permits, and all permits in Amity, Carlton, Sheridan, Willamina and Yamhill, come from the county; check farm-use zoning.
Farm-use zoning and winery limits can decide what is buildable.
Cascadia design reaches the valley.
Oregon requires it for almost any paid job; the exceptions are casual work under $1,000 and owners working on their own property.
An owner may do electrical work on their own home and plumbing work not done for hire; otherwise the installer needs the state trade licence.

Inspections in Yamhill County
Standard checkpoints include footing and foundation, under-floor and slab, framing, rough-in electrical, plumbing and mechanical, insulation and energy, fire systems on commercial work, and final, with occupancy approval before use. Farm-zoned and winery parcels add siting and use-specific verification.
Many Oregon jurisdictions take inspection requests online, several through the state ePermitting system; confirm the method Planning and Development uses and give the notice it asks for.
Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, the seismic and energy documentation, product listings and your correction responses available on site.

Permit records in Oregon sit with the authority that issued them — where Planning and Development administers the code, it holds the building permit, the inspection history and the certificate of occupancy for work in unincorporated Yamhill County. Many jurisdictions expose permit search through the state ePermitting portal. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was.
The code is statewide, but the counter is local. Fees, submittal lists, review turnaround and land-use requirements are set by the administering jurisdiction; the technical code is not. Confirm current requirements, fees and review turnaround for your filing date.
These are the primary sources behind this guide. Codes, fee schedules and portal procedures change — confirm the position for your filing date.

Frequently asked questions
Where do I get a Yamhill County building permit?
From the Planning and Development Department in McMinnville, for unincorporated areas, for Amity, Carlton, Sheridan, Willamina and Yamhill, and for electrical permits in the other cities; McMinnville, Newberg and the other larger cities issue their other permits.
Are there special rules for wineries and tasting rooms?
Yes. Farm-use zoning and Oregon’s winery and farm-based hospitality rules govern what wineries, tasting rooms and events are allowed; settle land use before design.
Is the building code different from the cities?
No. Oregon runs one uniform code statewide; what differs is the administering office, the fee schedule and the land-use rules.
Inspections are where schedules slip.
Get a free quote →Do I need a contractor licence for a small county job?
Almost always. Oregon requires a current CCB licence for construction work of any size; the exceptions are work under $1,000 that is casual, minor or inconsequential, by someone who does not advertise as a contractor, and owners working on their own property who are not building to sell.
Does seismic design apply here?
Yes. Cascadia seismic design reaches the valley; pull site-specific values from the state Design Criteria Hub.
How do I run a Yamhill County permit search?
Ask the county for its permit search; the permit and inspection history sit with the authority that issued the permit.
