Top Redmond neighborhoods for ADU investment include Downtown / Town Center, Canyon Rim Village, Rimrock Estates / Rimrock, Obsidian Estates / Obsidian Meadows, Eagle Crest.

Property Eligibility
Is My Redmond, OR Property Eligible for an ADU?
Redmond homeowners benefit from California's state ADU law — one of the most permissive frameworks in the country since 2020. Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Redmond under California state law. Redmond requires owner occupancy — the property owner must reside in the primary home or the ADU. Ministerial permit approval — no neighbor input or discretionary design review.
Multi-Family Property
Up to 2 detached ADUs plus JADUs (Junior ADUs) within the existing main structure are permitted under California state law. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 33% of Redmond homes are in an HOA. California law (AB 670) prohibits HOAs from banning ADUs outright, but they can impose reasonable architectural standards. Our drawings include HOA submission formatting.
Historic Districts
Yes - in historic/local landmark properties and for properties within 100 ft of the canyon; otherwise no (exempt from Site & Design Review)
Always verify eligibility with Community Development Department before designing.
