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.

An updated Permit Data Model that includes relationships between the component feature classes. The Dissolved Use Impacts (SDOT.V_SU_PERMIT_USE_IMPACT_DISS) feature class is derived from dissolving the Use Impacts (SDOT.V_SU_PERMIT_USE_IMPACTS) feature class by Permit Number. The Impacts feature class is the Use Impact street line segments that are associated with any give Permit point (V_SU_PERMITS). The relationships connect the Permit points to the Dissolved Use Impacts and then the Dissolved Use Impacts to the component Use Impacts. This data model allows you to see all impacted street line segments associated with any given Permit easily, while also being able to drill down to any specific Use Impact for a given Permit. Service is constructed for use in the Right of Way Map. Data set to Nightly Refresh. Any Questions or Concerns contact the SDOT Street Use Data and GIS Team: Craig Moore/Bryan Bommersbach

Permit records from the City of Seattle permitting system for building permits that create or demolish attached accessory dwelling units (AADU). Records begin in 1990 and are through the current year quarter.The permits in this layer are those that have either been completed or are currently issued. 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. Unit types will be visible only for the time period they were in the code. For example, small efficiency dwelling units were not created in the code until 2016 and so will not appear as a type until that year.There may be multiple permits at any given address.

Street vacations allow property owners to petition the Seattle City Council to acquire public right-of-way next to their property from the City. Street vacations “vacate” the public’s right to use a street and return it to private property. Street vacations are only applicable when there is an adjacent development project planned. The Street Vacation Policies state a preference for retaining right-of-way in neighborhood residential zones. In addition to the basic street purpose of access and utilities, streets in residential areas provide for things like open space, consistency in the development pattern, natural drainage, wildlife corridors and other things. For more information, please visit this City website.

Feature class containing all Seattle Department of Transportaion Street Use permits uses recorded since 2012. Street Use permits are required for certain activities in the public right of way, including private road work, material storage, and vending or café serving. Locations in this feature class are tied to the closest available address. For permits relating to building development or business activities these addresses are those of the site, but for types of work that span multiple streets an avilable adjacent address is chosen. This feature class contains one record per permit per use, resulting in repeated permit information between use records on the same permit

How were URMs in this database identified?

SDCI compiled an inventory of URM buildings from various visual and permit research surveys performed over the years. This inventory was validated by reviewing photographs of the buildings, visiting selected buildings to view the exterior construction details, and reviewing permit records and other documents, to verify each building should be included. The 2016 Report to Policy Committee on URM List Validation provides a detailed description of the data validation process.

Are all of Seattle’s URMs included in this database?

This URM database is intended to be a comprehensive inventory of URM buildings in Seattle. There may be URM buildings that were not identified during the City’s inventory process; if a building is found to contain URM load bearing walls and is not included in the inventory, it will be classified as a URM and subject to future mandatory retrofit requirements.

How often is this database updated?

The URM database is maintained regularly by staff, and updates are pushed to this dataset weekly.

How does the City recognize URM buildings as retrofitted?

A URM building owner must provide the required documentation and follow submittal procedures to demonstrate compliance with Seattle Existing Building Code section 304.5.1. This code section establishes a minimum standard for a URM to be recognized as retrofitted. Once SDCI approves this documentation, the building’s status in the “Confirmed Compliant Retrofit” column will be updated to “Yes”. An adjacent column, “Retrofit Method per SEBC 304.5.1”, will be updated to reflect the appropriate level of completed retrofit. See page 3 for further description of columns and field values.

When will URM retrofits be required?

Owners can undertake a voluntary retrofit at any time. Owners must retrofit URM building parapets (any wall that continues vertically past the roofline) when they are doing other permitted construction work in the building. (Per Seattle Existing Building Code 302.9 and A113.6.) The SEBC currently requires that buildings be seismically retrofitted if owners are conducting a major renovation, occupying a vacant building, or changing the use or occupancy of the building. Future mandatory requirements:

The City will not require a mandatory retrofit until financial and supportive resources have been clearly identified. The City passed Resolution 32033 in 2021 guiding the development of a Seattle mandatory URM retrofit program. The resolution recommends a variety of potential funding opportunities and financial incentives to reduce the financial burden on building owners required to seismically retrofit their URMs. Once the City has adopted a mandatory URM Retrofit Ordinance, building owners will be required to meet retrofit deadlines according to the timeline associated with their URM’s “Vulnerability Classification” column in the URM database.

What are the URM Vulnerability Classifications and their proposed mandatory compliance timelines?

URM Vulnerability Classification

Proposed Mandatory Retrofit Compliance Timelines

Critical vulnerability: emergency service facilities and schools

7 years

High vulnerability: buildings over three stories and located in poor soil areas (i.e. liquefaction and slide areas), and buildings with occupancies designated as public assembly.

10 years

Medium vulnerability: all other buildings

13 years

How is the Vulnerability Classification determined?

A URM building’s occupancy type, height and poor soil conditions factor into its vulnerability classification.

Building Height: taller URM buildings are more susceptible to damage in an earthquake. URM buildings with more than three floors, those with values greater than three in the “Stories” column of the URM database, and located in poor soil conditions, are classified as High Vulnerability.

Poor Soil Conditions:

Liquefaction occurs when loose, saturated soils lose their strength due to ground shaking (usually from earthquakes). Loss of soil strength can cause sinking, fracturing, and sliding of the ground surface causing significant damage to roads and buildings. Taller URM buildings located in liquefaction prone areas, designated as “Yes” in the “Liquefaction Prone” column are classified as High Vulnerability. Data informing this column was updated in 2023 and impacted the Vulnerability Classification of a number of URMs. Learn more about Seattle’s Liquefaction-Prone Areas and updates. Landslides can be caused by the shaking associated with earthquakes. Taller URM buildings located in landslide prone areas are classified as High Vulnerability in the URM database. Two columns provide information on landslide hazards “Steep Slope” and “Potential Slide Area”. These columns correspond with the City’s mapped Environmentally Critical Areas (ECA) code. A value in either column (for URMs with 3+ stories) contributes to a URM High Vulnerability classification.

Occupancy Types:

Emergency Services are facilities that would be needed in a major catastrophe. Examples of Emergency Services include police and fire stations, hospitals, and communications centers. URMs designated as “Emergency” in the “Occupancy” column of the URM database are classified as Critical Vulnerability. Schools: are defined as all public and private educational facilities from nursery school to university. Schools are represented as “Schools” in the “Occupancy” column of the URM database and are classified as Critical Vulnerability. URM buildings are a collapse hazard to occupants, with risk of injury and death; a larger number of occupants increases the number of people at risk to the collapse hazard and are thus designated as High Vulnerability in the URM Database. High occupancy URM buildings are as classified as “Public Assembly” in the “Occupancy” column. Examples include theaters, auditoriums, community centers, performance halls and churches.
