County Summary

Corvallis has a vacancy between 3 and 5%. The city indicates 300-400 units were built in 2020 (equivalent to adding 1-2% to housing stock), with 700 more in the known pipeline for the next several years. The survey response from Corvallis indicated that the housing crunch is exacerbated by limited land, limited residential zoned potential, and onerous parking regulations that create issues for growth, especially after 2035. Housing demand appears to be affecting the region and increasing development pressure in smaller cities. For example, Philomath has attested that 600 of those housing units were added in last 5 years, with around 200 units already in the next 5-year pipeline. That represents a significant 10-year expansion to Philomath’s housing supply and population. Additionally, the City of Adair stated it has permitted ~200+ new units since 2018, about half of which are still being built. Like Philomath, this represents significant growth in this small city with strong access to both Corvallis and Albany job centers.
