Under state law and Washington County Community Development Code (CDC) standards, middle housing includes duplexes, triplexes, quadplexes, townhouses and cottage clusters that meet certain criteria. Middle housing regulations allow:
- Middle housing in urban unincorporated residential districts where single-detached dwellings (residences) may be allowed: R-5, R-6, R-9, R-15, R-24, R-25+, R-6 NB, R-9 NB, R-15 NB, TO:R9-12, TO: R12-18 and TO: R18-24.
- Find your property’s land use district (Intermap)
- More housing units per site than what's allowed for other housing
- Provisions to make it easier to keep existing homes and Accessory Dwelling Units on a lot where middle housing is proposed
- Certain design and siting standards
- An expedited land division process through which a separate lot can be created for each middle housing unit
