Which King County cities we serve — and which we don’t yet
One city is live: Seattle. The other 38 cities and towns in King County, and every unincorporated pocket between them, are not served yet — and we would rather print that here than take an order we cannot fill. Pick your city below to see exactly where you stand.

What “not served yet” actually means
It is not a licensing question or a travel question. It is a data question, and it splits cleanly in two.
The measured report cannot be produced at all
The buildable envelope, setbacks, tree tiers, critical areas, utility feasibility and unit count are measured from City of Seattle layers — parcel and building outlines, the SDCI zoning detail, the ten Environmentally Critical Areas layers, the 2021 tree crowns and protected-tree layer, the SPU sewer and water services, the SDCI transit walksheds. There is no equivalent wired in for any other city, so the address is refused rather than answered badly.
The records dossier would lose 9 of its 15 sources
Outside Seattle these 6 still apply, because they are county or state records:
And these 9 do not, because they are City of Seattle services:
A dossier missing the permit history, the violations, the side-sewer card and the tank permit is not the product described on this site, so it is not sold outside Seattle at any price.
If you are outside Seattle, this much is still true for you
Free, and county-wide or statewide by nature. Nothing here needs a Seattle parcel.
Everything else on the site — the guides, the free assistant and the neighborhood profiles — is written against Seattle’s code and should be read as Seattle-specific.
What a city needs before it goes live here
Each new city is its own build: its own records, its own code, its own hookups. These six are the gate, in the order they block a report.
- 1
A parcel and building layer
Boundaries and building footprints precise enough to measure a buildable rectangle. Without footprints there is no setback math, only a guess.
- 2
The city's own zoning layer, with dimensional standards
Zone per parcel, plus the code text that turns a zone into setbacks, height, lot coverage and a floor-area budget.
- 3
A critical-areas layer
Slope, slide, liquefaction, wetland, flood. This is the layer that decides whether the fast permit path is even available.
- 4
The city's tree regulations, mapped
Tier definitions and, ideally, a crown layer. Trees move footprints more often than setbacks do.
- 5
Utility as-builts
Side sewer and water service records. A cottage with nowhere to drain is not feasible at any price.
- 6
A permit record we can read by address
Without it, the dossier cannot show what has already happened on the property — which is the whole product.
When all six can be read by address for a city, that city gets its own page here, its own record list and its own products — and this page stops saying no to it.
In Seattle? Here is the whole coverage picture
Seattle is the one city this site serves. See every record source by owner, which are Seattle-only, and the measured neighborhood profiles.
Questions people actually ask
Do you serve Bellevue, Kirkland, Renton or Shoreline?
Not yet. Seattle is the only city served today. The zoning, critical-area, tree and utility layers this site measures are City of Seattle services, and 9 of the 15 record sources behind the property dossier are City of Seattle datasets. An address outside Seattle is refused before any money changes hands.
Do you cover unincorporated King County?
No. Outside a city limit, permitting is King County Department of Local Services under the county's own ADU code, and the City of Seattle layers this engine measures do not apply at all.
The King County Assessor covers the whole county — why not the rest of it?
Because the Assessor is 6 of 15 sources. Outside Seattle the King County Assessor, Recorder, GIS and Treasury records and the Washington Ecology and DNR layers still apply, but the permit history, the code violations, the side-sewer card, the water-service record, the heating-oil tank permit, the zoning history and the landmark status do not — and neither does a single layer the buildable-envelope measurement is built on.
What happens if I type a non-Seattle address into the lot check?
It answers that the address is outside the Seattle service area and stops. No report is generated and no payment is taken.
When will my city be added?
There is no date, and a date would be a guess. A city goes live when its parcel, zoning, critical-area, tree, utility and permit records can each be read by address — the checklist is published on this page. Telling us which city you are in is what moves it up the list.
