Permit records from the City of Seattle permitting system for building permits that create or demolish housing units. Records begin from the beginning of the previous decade from the current quarter year.

The permits in this layer are those that have been completed. This data does not contain records for those permits that were issued but were not completed so are therefore not comparable to statistics that report permit issuance.

Each record represents the number of units added or demolished for each housing type in the project. Therefore a single building permit may appear multiple times if there are a mix of unit types in the project.

Housing unit types reflect the unit types regulated by the building codes and change through time. There has been no attempt to standardize these types and therefore reflect the unit types that existed at the time the permit was issued.

There may be multiple permits at any given address.

1. The average price of sales within the
   census tract for the specified year, balancing between nominal sale
   price and sale price per square foot.
2. The change in average sale price (again balanced between nominal sale price and price per square foot) from the previous year.

Census 2020 blocks with the Washington State Office of Financial Management Small Area Estimates Program (SAEP) estimates. Enhanced with City of Seattle council districts and growth management areas.

PLEASE BE AWARE, the urban village and comprehensive plan area designations are subject to change annually.

Estimates are annual April, 1 for the 2010-202X with the most current year added Q4 of that year.

(SAEP) estimates are meant to provide a consistent set of small area population and housing data for statewide applications. SAEP estimates are generated by the Washington State Office of Financial Management for census areas and other areas of statewide significance.

Before using the SAEP estimates, please see the SAEP User Guide to gain a better understanding of the data and methods behind the estimates as well as limitations in their use. For more specific information about the 2020 data release, please see the User Notes and Errata document.

Please note that SAEP estimates are NOT the official state population estimates used for revenue distribution and program administration related to cities and counties. Users interested in city and county estimates should see the state's official April 1 population estimates program.

Permit records from the City of Seattle permitting system for building permits that create or demolish housing units. Records begin in 1990 and are through the current year quarter.

The permits in this layer are those that are currently issued. This data does not contain records for those permits that were issued but were not completed, cancelled or withdrawn.

Each record represents the number of units added or demolished for each housing type in the project. Therefore a single building permit may appear multiple times if there are a mix of unit types in the project.

Housing unit types reflect the unit types regulated by the building codes and change through time. There has been no attempt to standardize these types and therefore reflect the unit types that existed at the time the permit was issued.

There may be multiple permits at any given address.
