Fauntleroy · NR · 4,400 sq ft lot
(Fauntleroy, NR): the backyard-cottage screen does not resolve — verification readiness is unknown from the evidence on file.
Where the screen stops
Stages are evaluated in a fixed order. A later constraint is only named as the reason once every earlier stage has resolved, so an unknown never gets reported as a failure.
- 1. legal capacityPasses
The verified NR rule set permits a detached accessory dwelling unit.
- 2. physical fitPasses
The citywide screen found the lot geometry sufficient for a detached backyard cottage, subject to field verification. Lot on record: 4,400 sqft, regular, alley access.
- 3. financial plausibilityPasses
Under screening rule gap-dadu-financial@v1, modeled income covers modeled debt service at the favorable end of the assumed cost range.
- 4. affordable-program applicabilityPasses
Public programs whose site conditions are met here: king-county-home-improvement-exemption, seattle-pre-approved-dadu-plans.
- 5. verification readinessUnknown
1 screening input still needs evidence before this parcel's result can be relied on.

Limitations of this screen
- Public-data screen only. It includes no site visit, survey, title review, or permit determination.
- Legal capacity comes from joined zone rules; physical fit comes from the citywide parcel screen. A parcel can pass one and not the other.
- The citywide physical screen covers the NR, RSL, LR, MR, HR, and legacy SF residential zone families. Outside them physical fit is reported as unknown, never as a physical failure.
- Current SMC 23.42.022 (Ord. 127375/127376, 2025) allows accessory dwelling units as a housing use in every zone where housing uses are allowed. The former 2023 lowrise principal-unit-type gate and 650-square-foot cap no longer apply; the current cap is 1,000 square feet.
- Detached ADUs are prohibited by the Shoreline Master Program. A parcel is blocked when any portion intersects the official Seattle Shoreline Environments overlay; mapped boundaries still require parcel-level confirmation with SDCI.
- Financial plausibility applies a published screening rule to explicit planning assumptions and a HUD SAFMR rent basis. It is not a bid, quote, appraisal, or forecast, and no Seattle cost calibration supports it.
- The financial stage varies only by ZIP-level one-bedroom HUD SAFMR. All parcels in the same SAFMR geography receive the same result under the citywide cost assumptions; this is not parcel-specific financial evidence.
- Financial geography patterns are rent-basis patterns, not observed construction-cost or project-outcome patterns. They must not be used to deprioritize investment in the neighborhoods they name.
- Public program applicability describes whether a listed program reaches this site. Household eligibility — income, ownership, occupancy, disability, financing — is never collected or inferred.
- The first detected blocker is the first blocking condition under the published stage and within-stage detection order, and attribution is withheld when an earlier stage is unknown. It is not a claim that other constraints matter less.
- Stages are evaluated independently wherever their inputs allow, so a later-stage blocker does not imply that earlier stages passed.
