Hillsboro, OR — Mobile Home Park Investments

Hillsboro, Oregon is the fifth-largest city in the state with approximately 110,000 residents and is one of the most economically dynamic communities in the Pacific Northwest. As the western gateway to Portland’s “Silicon Forest” technology corridor, Hillsboro is home to Intel Corporation’s largest global campus — employing over 20,000 workers — along with dozens of technology, semiconductor, and advanced manufacturing companies. For mobile home park investors, Hillsboro offers a rare combination of high-wage employment driving housing demand and persistent affordability constraints that make manufactured housing a critical part of the local housing mix.

Hillsboro Market Overview

Hillsboro has experienced remarkable growth over the past three decades driven by technology sector expansion in Washington County. The city sits at the western terminus of the MAX Blue Line, with excellent freeway access via US-26 and OR-8 connecting to Portland and I-5. Despite its tech-economy reputation, Hillsboro’s workforce includes a substantial agricultural and service sector, and the city has significant Spanish-speaking and Latino communities who represent an important segment of the manufactured housing resident base. Hillsboro’s median household income (approximately $72,000) is higher than the Portland metro average, supporting strong lot rent capacity.

Why Hillsboro for Manufactured Housing Investment

Intel’s massive Hillsboro campus (D1X fab, Jones Farm, Ronler Acres) employs thousands of direct workers and supports a large supply chain and contractor workforce — many of whom seek affordable housing within short commute distance. Washington County’s robust employment base also includes Nike World Headquarters (Beaverton, adjacent), Tektronix/Danaher, and numerous semiconductor and clean-tech firms. The concentration of stable, well-paying employment creates strong demand for all housing types including manufactured housing communities, which serve both lower-income service workers and some tech workers seeking affordable alternatives to high apartment rents.

Local Lot Rent Data and Trends

Hillsboro and Washington County mobile home park rents have risen substantially, reflecting the area’s economic strength. In 2015, parks in the Hillsboro area averaged $500–$580 per month. By 2025, well-maintained communities are achieving $860–$960 per month, with some parks near Intel or transit corridors reaching $1,000+. The combination of high incomes in the broader employment base and severe housing scarcity (Washington County has limited land for new development within the UGB) creates strong structural support for continued lot rent appreciation. Washington County’s manufactured housing market is considered one of the tightest in the Pacific Northwest.

Zoning and Permitting Landscape

Hillsboro operates under Washington County’s framework as well as its own municipal zoning code. Washington County has historically maintained manufactured housing community zoning in established areas, recognizing the housing type’s critical affordability role in an expensive market. Oregon state law’s strong protections for manufactured housing communities apply fully in Hillsboro. The city’s rapid growth has created significant pressure on all housing types, and local planners have generally been supportive of maintaining existing affordable housing stock including manufactured housing communities.

Infrastructure: City Water and Sewer

Hillsboro is served by the Tualatin Valley Water District (TVWD) for water service and Clean Water Services for wastewater treatment — two of the most well-capitalized utility authorities in the Pacific Northwest. Both agencies have made significant infrastructure investments over the past decade and maintain high service reliability standards. Most established manufactured housing communities in Hillsboro are connected to these municipal systems, which is a significant operational advantage compared to parks on private wells or package treatment plants.

Proximity to Portland Metro Employment Centers

Hillsboro’s MAX Blue Line terminus gives residents direct rail access to all major metro employment centers. Intel Hillsboro campus is accessible by shuttle from MAX stations. The Sunset Transit Center provides park-and-ride connections. Key employment destinations from Hillsboro: Intel campuses (5–10 minutes), Nike World Headquarters in Beaverton (10 minutes), Portland central business district (35–40 minutes by MAX), Oregon Health and Science University (45 minutes). The west side tech corridor along OR-217 and OR-26 concentrates thousands of additional jobs within easy commute distance.
