Eugene City Council Approves Housing Overlay Zone, Relaxes Lot Size Rules in Four Neighborhoods

Eugene's city council voted 7-2 on Wednesday to approve a new housing overlay zone that permits smaller lot sizes in four neighborhoods on the city's south and east sides. The ordinance, adopted after two years of planning, eliminates minimum lot width requirements of 50 feet in favor of a flexible 35-foot standard in residential areas currently zoned for single-family homes. The move applies to roughly 340 acres across the River Road, Amazon, Willamette, and South Hills neighborhoods.

The council's action reflects a widening pressure across mid-sized U.S. cities to increase residential capacity without expanding city limits. Eugene's population has grown to approximately 176,000 residents, up 8 percent since 2010, and median home prices have climbed 34 percent since 2020 according to Zillow data. Local planners say the overlay zone is designed to allow property owners to subdivide existing lots and build accessory dwelling units on smaller footprints, making homeownership more feasible for families and first-time buyers.

What This Means for Eugene Homeowners and Renters

The ordinance does not require existing homes to be demolished or modified. Instead, it permits new construction on subdivided parcels and allows for two-unit buildings on single-family lots in participating neighborhoods. The city's planning department projects the change will enable construction of 45 to 65 additional housing units per year in these four zones, compared to the current baseline of about 35 units annually. For renters, the expected 15-20 percent increase in available units over five years may ease pressure on the tight rental market. Eugene's rental vacancy rate currently sits below 3 percent, forcing many tenants to compete for limited stock.

The ordinance preserves existing setback and parking requirements. Developers must still provide off-street parking and maintain 20-foot front yard setbacks. The city's code allows homeowners to opt out by deed restriction, protecting those who prefer single-family zoning rules to remain unchanged. Neither the River Road neighborhood association nor the Amazon neighborhood association formally opposed the measure at public hearings. The South Hills Neighborhood Association requested, and the council approved, a five-year review clause to assess the overlay's effects before determining whether to extend it beyond 2031.

Budget Impact and Implementation Timeline

The planning department allocated $185,000 from this fiscal year's budget to implement the new zoning rules, including updated code language, staff training, and public outreach. The city expects to begin accepting rezoning applications under the new overlay in September 2026. Property owners in the four neighborhoods will receive mailed notices and have 60 days to request deed restrictions if they wish to maintain the previous lot size requirements. City staff said the measure aligns with Oregon's statewide housing law, which took effect in 2022 and requires cities over 10,000 residents to allow duplex construction in single-family zones.

Councilor Jennifer McConnell, who chairs the planning and development committee, noted the council does not anticipate requiring additional infrastructure spending in the short term, though future water and sewer capacity reviews may be necessary if buildout accelerates. The two council members who voted against the ordinance, Tom Viall and Iris March, raised concerns about neighborhood character changes and the pace of implementation but did not request further delays.

The city will host open office hours in each of the four neighborhoods on July 24 and August 7 to answer homeowner questions. The planning department can be reached at 541-682-5086 or planning@eugene-or.gov.
