Washington County, Oregon
North Plains
A city of roughly 3,500 people on the farmland edge of Washington County, 17 miles from downtown Portland, currently deciding how much bigger it wants to get.
The Overview
North Plains incorporated in 1963 with about 500 residents. The 2020 Census counted 3,441, and the City now describes the population as approximately 3,600. It occupies just over one square mile, sitting immediately off U.S. 26 northwest of Hillsboro.
Buyers come here for a specific trade: a genuinely small town with its own police department, staffed under contract by the Washington County Sheriff’s Office since 2019, plus a library and parks department, on a highway that puts Intel and Genentech in Hillsboro about 15 minutes away and downtown Portland around 30 minutes off-peak. It draws Silicon Forest employees who want a rural buffer, families who want a town where kids can ride bikes, and buyers who want acreage outside city limits while staying inside the metro commute shed. The 2020 Census recorded 82.7 percent owner-occupancy and a median age of 34.4. This is a town of families who bought, not renters passing through.
The defining current issue is growth. The City Council approved an 855-acre urban growth boundary expansion in September 2023. Voters rejected it by 71 percent in a May 2024 referendum. A 2024 state law tried to make such expansions non-referable, but a Washington County judge struck it down as unconstitutional in September 2024, and the City dropped its appeal in a February 2025 settlement. The voters’ rejection stands. The City has since run a scaled-back concept planning process roughly 300 acres smaller than the rejected proposal. As of mid-2026 the city had completed phase two of public engagement and was drafting a concept plan. That process has since stalled amid significant turnover on the city council and in city management, so the timeline should be treated as uncertain. Anyone buying here should understand this is unresolved.
The Housing Stock
The oldest housing sits in the original grid near Commercial Street and the town core: early-1900s through mid-century homes on small, flat lots, with the plat itself dating to 1910. Around that core are subdivisions from the 1990s and 2000s, which is where most of the growth from 1,605 residents in 2000 to 3,441 in 2020 landed. Those are conventional two-story tract homes on modest lots, generally on city water with Clean Water Services handling wastewater. There has been continued newer construction on the town’s edges since.
Outside the city limits is a different market entirely: farmhouses, manufactured homes and custom houses on one to forty-plus acres, on private wells and septic systems, most of it zoned Exclusive Farm Use or rural residential. Those properties look like bargains on a price-per-square-foot basis and are anything but simple. EFU zoning restricts what can be built, who can build it, and sometimes who can buy it. Financing, appraisal and land-use due diligence on rural North Plains parcels take longer than an in-town purchase, and they should.
Who It Suits
- Hillsboro campus employees who want a rural setting with a 15-minute drive to work
- Families who want a small-town environment while staying in the Hillsboro School District
- Buyers seeking acreage, outbuildings or livestock capability inside the Portland commute shed
- Golfers and outdoor-oriented buyers, since Pumpkin Ridge Golf Club is just outside town and the coast is within an hour
- Buyers who want a genuinely walkable small downtown and a town-scale civic life
- People comfortable owning in a place actively debating its own growth trajectory
Local Knowledge
- Schools are Hillsboro School District. North Plains Elementary feeds Evergreen Middle School and Glencoe High School. High school students commute to Hillsboro.
- Service providers are split: the City provides drinking water, library and parks; Clean Water Services handles wastewater; North Plains Police Department is backed by the Washington County Sheriff; Tualatin Valley Fire & Rescue covers fire from a station on NW Commercial Street.
- Jessie Mays Community Park and Community Center is the civic hub. The Ghost Creek Walking Path runs about a mile; the West Union Pedestrian Path is the other main route.
- The Elephant Garlic Festival is the town’s signature event, held the second weekend of August at Jessie Mays, with a Saturday morning parade, car show, vendors and live music. It is a real community institution.
- Pumpkin Ridge Golf Club, just outside town, hosted the U.S. Women’s Open in 1997 and 2003 and has more recently hosted LIV Golf. North Plains Gliderport is also nearby.
- U.S. 26 access is the whole ballgame. Hillsboro employment centers are a short drive; Portland is roughly 17 miles east. There is no light rail here; the nearest MAX station is in Hillsboro.
- Where the UGB boundary lands, and what gets zoned residential versus industrial, will shape property values on the town’s edges for the next two decades. Data center and warehouse siting was a major driver of the 2024 opposition.
Before You Write an Offer
- On rural parcels, verify zoning before anything else. EFU and rural residential designations limit building, partitioning, home occupations and accessory dwellings. Get the county zoning and any existing land-use approvals in writing.
- Well and septic on out-of-town properties: pull the well log, test flow rate and potability, and get the septic system inspected and pumped with the county permit record reviewed. Failed or undersized systems are expensive and sometimes not replaceable on the same footprint.
- Understand what the UGB decision could mean for your specific parcel. A property adjacent to the expansion study area could see farmland become subdivision, or stay farmland. Ask where the current draft concept plan places your address.
- Financing and appraisal on acreage. Rural properties with outbuildings, multiple dwellings or large acreage often do not fit conventional loan programs and can appraise unpredictably. Line up the right lender before you write.
- Check flood mapping and drainage. This is low, flat ground near McKay Creek and Dairy Creek on the valley floor. Confirm FEMA flood zone status and ask about seasonal standing water.

Where the boundary lands matters enormously if you own or are buying on the edge of town. I follow this closely. Ask me what it means for a specific address.
