Historic-resources commission urges coordination as Oregon's middle housing law reaches local planners

The Benton County Historic Resources Commission discussed the implications of Oregon's middle housing law for designated historic districts and encouraged coordinated action among neighboring city planning teams and state preservation authorities.

Commission members said the state statute allows single-family lots to be redeveloped as duplexes, triplexes and other middle-housing types without an explicit exemption for historic districts. Members raised concerns that, absent targeted guidance or process changes, developers could pursue demolitions or replacements inside historic neighborhoods and that inconsistent city-level exceptions would complicate preservation efforts. Participants recommended convening planners from Albany, Monmouth and Corvallis and suggested engaging the State Historic Preservation office to develop a unified strategy.

Petra Sheets, Benton County planning director for historic resources and interim community development director, told the commission the county's comprehensive plan update will treat housing as a top-tier theme and that staff will loop historic resources into the outreach and code-update process once an outreach consultant is under contract this summer. She said the planning commission will lead town halls for unincorporated areas and small cities in the fall and winter, which the HRB can inform.

Commissioners also noted practical issues likely to arise under middle housing rules, including parking standards and timing for public notification. They discussed options one jurisdiction has used to limit demolition of contributing properties, and debated whether local deconstruction requirements or more stringent review of "contributing" vs. "noncontributing" historic properties could reduce loss of character.

The commission agreed to pursue a conference call among interested planners and relevant preservation partners to identify best practices and next steps. Members said any state-level guidance from the State Historic Preservation office would be helpful to ensure consistent application across city and county boundaries.

The commission did not vote on a formal resolution but asked staff to track city actions and to organize a planning-level meeting with neighboring cities and SHPO representatives.
