Book Roosevelt feasibilityFrequently asked
Can I build an ADU in Roosevelt, Seattle?
Yes — every residential-zoned lot in Roosevelt qualifies for at least one ADU under RCW 36.70A.681 and Seattle's implementing code. Variables in Roosevelt specifically: (1) lot size and shape — Roosevelt has a mix of original platted lots and post-1960 subdivisions, which changes setback geometry; (2) tree retention — mature Roosevelt trees over a measured DBH may require an exceptional-tree review; (3) historic overlay — pockets of Roosevelt are in a conservation overlay that adds design review. We pre-check all three at feasibility.
What does an ADU cost in Roosevelt?
Roosevelt ADU all-in cost tracks Seattle citywide medians: $300–$400/sqft for a turn-key 1-bedroom DADU. Roosevelt-specific variables include alley access (lowers crane and material handling cost ~$4–9K), older sewer mains (occasionally require side-sewer repair adding $6–18K), and tree-protection fencing. We have built in Roosevelt every year since 2017 and our bid accuracy on Roosevelt lots is within ±8% of contract on 90% of jobs.

What rent will a Roosevelt ADU generate?
2026 Roosevelt 1-bedroom DADU rents land in the band typical for the surrounding Seattle submarket, generally $2,050–$3,150/mo long-term with a 5–10% premium for true detached privacy over attached units. Mid-term furnished rates run 15–25% higher when within walking distance of transit or a hospital corridor. Our Roosevelt rental comps update quarterly from on-market and recently-leased pulls.
How long does a Roosevelt ADU project take end-to-end?
Signed feasibility to keys in hand for Roosevelt projects: 9–14 months — 6–8 weeks design, 10–16 weeks Seattle permit, 18–26 weeks construction. Roosevelt lots with alley access tend to finish at the fast end because staging and crane setup are simpler. Lots requiring driveway construction or grading run the long end. Gantt at contract, weekly updates throughout.

What's special about building in Roosevelt vs other Seattle neighborhoods?
Three Roosevelt-specific factors: (1) the typical lot age — pre-1950 Roosevelt lots often have undersized water services (3/4") that require upsize; (2) the tree canopy — Roosevelt's mature canopy means exceptional-tree review is more likely than in post-1990 Seattle neighborhoods; (3) the soil — Roosevelt's position on the Puget Lowland glacial till usually supports slab-on-grade. Our Roosevelt field experience streamlines all three.

Are there any HOA restrictions in Roosevelt?
Roosevelt is partly HOA-governed and partly fee-simple. Where HOAs apply, RCW 64.38.034 (effective 2024) blocks outright ADU bans, but ARBs can impose design covenants (siding material, roof pitch, façade articulation). We submit design concepts to ARBs in parallel with permit submittal, adding 4–8 weeks. Most Roosevelt HOAs approve when the DADU echoes the primary house's siding and roof material.
What permits and reviews trigger for Roosevelt ADUs?
Standard Seattle ADU permit + side-sewer + addressing + water capacity. Roosevelt-specific: tree-protection plan if any tree ≥24" DBH is within the construction zone; critical-areas screening if Roosevelt portion borders a mapped stream, wetland, or steep slope; drainage review if new impervious exceeds threshold (more likely on small Roosevelt lots). We pre-screen all three before submittal.

Can I do a basement ADU in a Roosevelt house?
Often yes — Roosevelt's housing stock includes many pre-1970 homes with full basements ranging 6'-2" to 8'-0" ceiling height. Basements ≥7'-0" with achievable egress windows convert cleanly at $145–$220K. Lower ceilings (<7'-0") require underpinning to lower the slab — adds $35–$65K plus permit complexity. We measure ceiling and check IRC R310 egress feasibility during initial site visit.
Does Roosevelt's zoning allow two ADUs?
Depends on the underlying zone — Seattle's middle-housing implementation under HB 1110/1337 allows two ADUs on most residential lots in Roosevelt (DADU + AADU, two AADUs, or stacked DADU). The combined cap is typically 2,000 sqft. Some Roosevelt subareas with critical-area overlays restrict to one ADU. We confirm zone designation and count at feasibility against your specific address.
