What’s Allowed in Bend, Redmond, Sisters, La Pine & Rural Areas

Accessory Dwelling Units (ADUs) continue to be one of the most popular ways Central Oregon homeowners add value, flexibility, and income potential to their properties. Whether you’re thinking about multigenerational living, a rental option, or simply increasing your home’s long-term value, here’s what you need to know about what’s permitted across Deschutes County cities and rural zones.

Why Build an Accessible ADU?

• Multigenerational living is one of the most common reasons people build an ADU.
• Accessibility matters: a visitable or universally designed ADU widens your buyer/renter pool and makes future resale easier.
• Cost savings: it’s much easier (and less expensive) to build with accessibility in mind from the start than to retrofit later.

Square Footage Limits by City

• Bend: 800 sq. ft. (+ additional 500 sq. ft. with conditions)
• Redmond: 900 sq. ft. (cannot be built in front of the primary home)
• Rural Deschutes: 900 sq. ft. (new rules as of Dec 2023 allow detached ADUs on 2+ acre lots; 5+ acres in southern county)
• Sisters: 800 sq. ft. (or 75% of the main home, whichever is smaller; requires an additional parking space)
• La Pine: Still unclear on specific limitations.

What’s New in ADU Codes?

• Dec 2023 – Rural Deschutes County began allowing detached ADUs on qualifying lots.
• Mar 2025 – Rural Deschutes County will allow attached ADUs.
• June 2025 – Bend City Council will vote on allowing a second ADU on a lot and a second kitchen in a primary residence.

Free Pre-Approved ADU Plan

• The Joel: A 576 sq. ft. pre-approved plan from the City of Bend with either a shed or gable roof option…and free!
• More Plans: Available via Sierra James, Hiatus Homes, and the Bend Chamber of Commerce’s guide for all things ADU’s

Accessibility Certification for ADU’s

Organizations like LiveAble Homes offer certifications searchable in the RMLS system. This makes it easier for buyers to find accessible properties—boosting both rental and resale value.

Key Takeaway

Building an ADU in Central Oregon isn’t just smart for today’s needs—it’s an investment in flexibility, family, and future value. Whether you want a rental, a guest suite, or a space for aging in place, knowing the local rules is the first step.
