Eugene tiny home zoning, ADU rules, THOW parking, and builder costs for Lane County, Oregon.
Last researched May 2026
Eugene offers a college-town feel with Willamette Valley access, strong bike infrastructure, and a walkable downtown. The climate is mild and wet, making well-insulated builds and good rain drainage important for tiny homes. Nearby rural areas around Lane County offer more land-based THOW options.
Eugene allows ADUs on most single-family lots under Oregon's statewide ORS 197A.425 baseline, with local standards in Eugene Land Use Code Chapter 9. The city follows HB 2001 middle-housing rules, permitting duplexes, triplexes, and cottage clusters in R-1 zones. THOW placement is not broadly permitted as a primary dwelling, but RV-classified tiny homes can be parked on private property with a primary dwelling subject to utility and setback rules. Always confirm specifics with Eugene Planning before siting.
Verify current requirements with your local planning department.
ADUs are allowed on most single-family lots under Oregon state law. As of May 2026, Eugene permits both attached and detached ADUs up to 800 sq ft (or 10% of lot area, whichever is smaller) with no owner-occupancy requirement and no additional off-street parking mandate. The city offers a Pre-Approved ADU Program with free ready-to-permit designs to reduce upfront fees, and an extra 7 ft of building height is allowed in R-2 through R-4 zones for roof slopes 6:12 or steeper. Confirm zone-specific setbacks and lot-coverage limits with Eugene Planning and Development before designing.
Communities, RV parks, and parking options in and near Eugene.
Eugene treats a tiny house on wheels as a recreational vehicle. Full-time occupancy on a residential lot requires the RV be secondary to a permanent primary dwelling, with utility hookups and compliance with parking and setback standards. Eugene does not currently have a Portland-style explicit RV-occupancy ordinance, so confirm with the Planning Division before placing.
