Neighborhood Overview
Ravenna is a family-oriented northeast Seattle neighborhood near the University of Washington, with generous 6,000–9,000 sq ft lots and Burke-Gilman Trail access. The ample yards and steady UW-driven demand make it excellent for detached ADUs.
Ravenna is a leafy, established neighborhood in northeast Seattle, defined by the wooded Ravenna Park ravine and its proximity to the University of Washington. The housing stock features classic Craftsman and Tudor homes on generous lots, many with mature gardens and alley access. Families are drawn to the area for its quiet streets, good schools, and walkability to University Village shopping. UW proximity creates consistent rental demand from graduate students, faculty, and medical staff at UW Medical Center, while the Burke-Gilman Trail offers car-free commuting. With lots commonly 6,000–9,000 sq ft, Ravenna is one of the better northeast Seattle neighborhoods for detached backyard cottages.
Ravenna lots are generous, commonly 6,000–9,000 sq ft, with frequent alley access and deep rear yards. These dimensions make detached ADUs highly feasible, and many lots can accommodate a full 1,000 sq ft cottage.

Special Considerations
Ravenna Park ravine
Lots bordering the ravine may have steep-slope or critical area overlays requiring geotechnical or arborist review.
Exceptional trees
Ravenna's mature canopy means many lots have trees over 24" DBH requiring a separate removal permit and arborist report.
Family-rental demand
Larger 2-bedroom ADUs perform well here given the family-oriented and faculty renter pool.
Permit and impact fees
Budget $20,000–$50,000 in Seattle DCI fees on top of construction.

Frequently Asked Questions
Are Ravenna lots good for detached ADUs?
Yes. Ravenna has some of northeast Seattle's more generous lots — commonly 6,000–9,000 sq ft with deep rear yards and frequent alley access. These dimensions make detached ADUs (DADUs) highly feasible, and many lots support a full 1,000 sq ft cottage. Seattle Municipal Code 23.44.041 governs DADUs, and HB 1337 protects detached units up to 1,000 sq ft.
How strong is rental demand in Ravenna?
Steady and reliable. Proximity to the University of Washington and UW Medical Center drives consistent demand from graduate students, faculty, and medical staff. Ravenna ADUs typically rent for $2,200–$3,000/mo, and larger 2-bedroom units do especially well with the family and faculty renter pool.
Will tree rules affect my Ravenna ADU?
Possibly. Ravenna's mature canopy means many lots have trees over 24" DBH, which are classified as exceptional under Seattle's tree ordinance and require a separate removal permit and arborist report. In most cases the ADU footprint can be sited to preserve protected trees. Our feasibility study maps trees and overlays on your parcel.
Is parking exempt for Ravenna ADUs?
Most of Ravenna qualifies. The U District Link station is nearby and several frequent Metro routes serve the area; properties within a half-mile of a frequent transit stop are exempt from ADU parking requirements. We confirm exemption status for your specific address.
