Abstract: This digitized collection contains approximately 90,000 images of Residential Assessment Records (a.k.a. “field cards”) created by the Tax Assessors Department of the City of Providence, Rhode Island. These cards contain information on structural conditions of buildings (e.g., grades of condition for foundations, walls, roofs, building materials, etc.) organized by, street address, and plat & lot number within the City of Providence. The verso of these cards contains structural diagrams, land valuations, and cost computations.

Providence City Field Assessment Records

Series 1: 1940

Creator: Providence City Archives

Language of materials: English

Repository: Providence City Archives

Record Group Number: RG 131.3

Scope and Content: The field cards were developed as a measure to accurately grade the value of a structure for tax purposes within the City of Providence. The strength of the collection, contemporarily, concerns the sections under “Land Valuation” on the verso of the digitized documents, particularly the status for which a building was zoned for (eg., house, apartment, industrial, or commercial structure, etc.). This information helps distinguish the maximum amount of tenants a residential building can have within code. Other areas of interest include quality assessments from building materials to structural condition (eg., cost computation of values before and after deductions of existing conditions and improvements of a structure).

Arrangement: The field cards are digitized and arranged in the Socrata database system accessed by address + plat/lot.

Access to the collection: There are no restrictions to access.

Use of materials: The materials are within public domain. However, researchers are kindly asked to cite the Providence City Archives if reproduced.

Preferred citation: Residential Assessment Records, RG131.3, Providence City Archives.

Update 10/31/2023: Sales are no longer filtered out of this data set based on deed type, sale price, or recency of sale for a given PIN with the same price. If users wish to recreate the former filtering schema they should set sale_filter_same_sale_within_365, sale_filter_less_than_10k, and sale_filter_deed_type to False.

Parcel sales for real property in Cook County, from 1999 to present. The Assessor's Office uses this data in its modeling to estimate the fair market value of unsold properties.

When working with Parcel Index Numbers (PINs) make sure to zero-pad them to 14 digits. Some datasets may lose leading zeros for PINs when downloaded.

Sale document numbers correspond to those of the Cook County Clerk, and can be used on the Clerk's website to find more information about each sale.

NOTE: These sales are filtered, but likely include non-arms-length transactions - sales less than $10,000 along with quit claims, executor deeds, beneficial interests are excluded. While the Data Department will upload what it has access to monthly, sales are reported on a lag, with many records not populating until months after their official recording date.

Current property class codes, their levels of assessment, and descriptions can be found on the Assessor's website. Note that class codes details can change across time.

Cook County 10-digit parcels with attached distances to various spatial features.

When working with 10-digit Parcel Index Numbers (PINs) make sure to zero-pad them to 10 digits. Some datasets may lose leading zeros for PINs when downloaded. 10-digit PINs do not identify individual condominium units.

Additional notes:

• Centroids are based on Cook County parcel shapefiles.
• Older properties may be missing coordinates and thus also missing attached spatial data (usually they are missing a parcel boundary in the shapefile).
• Attached spatial data does NOT all go back to 2000. It is only available for more recent years, primarily those after 2012.
• This dataset contains data for the current tax year, which may not yet be complete or final. Assessed values for any given year are subject to change until review and certification of values by the Cook County Board of Review, though there are a few rare circumstances where values may change for the current or past years after that.
• Rowcount for a given year is final once the Assessor has certified the assessment roll all townships.
• Data will be updated annually as new parcel shapefiles are made available.

Parcels with property tax-exempt status across all of Cook County per tax year, from Tax Year 2022 on, with geographic coordinates and addresses.

As of 2017 owner names in this dataset are no longer being regularly updated. We are trying to figure out a solution to this problem.

Properties of religious, charitable, and educational organizations, as well as units of federal, state and local governments, can be eligible for exemption from property taxes. The Illinois Department of Revenue (IDOR) ultimately grants qualified organizations with property tax exempt status, with additional administration by the Board of Review and/or Assessor. Learn more here, and see the Assessor's guidance for religious organizations here.

When working with Parcel Index Numbers (PINs) make sure to zero-pad them to 14 digits. Some datasets may lose leading zeros for PINs when downloaded.

Additional notes:

• Parcel entroids are based on Cook County parcel shapefiles.
• Newer properties may be missing a mailing or property address, as they need to be assigned one by the postal service.
• Exempt status for parcels changes regularly depending on the use and owner of a given parcel. Please contact Assessor.Exempt@cookcountyil.gov if you need additional information about parcels excluded from this dataset.
• Data will be updated monthly.
• This dataset contains data for the current tax year, which may not yet be complete or final. Assessed values and property tax-exempt status for any given year are subject to change until review and certification of values by the Cook County Board of Review, though there are a few rare circumstances where values may change for the current or past years after that.
• Rowcount for a given year is final once the Assessor has certified the assessment roll all townships.
• Current property class codes, their levels of assessment, and descriptions can be found on the Assessor's website. Note that class codes details can change across time.

Land, building, and total assessed values for all Cook County parcels, from 1999 to present. The Assessor's Office uses these values for reporting, evaluating assessment performance over time, and research. When working with Parcel Index Numbers (PINs) make sure to zero-pad them to 14 digits. Some datasets may lose leading zeros for PINs when downloaded. This data is parcel-level. Each row contains the assessed values for a single PIN for a single year. Important notes:Assessed values are available in three stages: 1) mailed, these are the initial values estimated by the Assessor's Office and mailed to taxpayers. 2) certified, these are values after the Assessor's Office closes appeals. 3) Board of Review certified, these are values after the Board of Review closes appeals. The values in this data are assessed values, NOT market values. Assessed values must be adjusted by their level of assessment to arrive at market value. Note that levels of assessment have changed throughout the time period covered by this data set. This data set will be updated roughly contemporaneously (monthly) with the Assessor's website as values are mailed and certified. However, note that there may be small discrepancies between the Assessor's site and this data set, as each pulls from a slightly different system. If you find a discrepancy, please email the Data Department using the contact link below. This dataset contains data for the current tax year, which may not yet be complete or final. Assessed values for any given year are subject to change until review and certification of values by the Cook County Board of Review, though there are a few rare circumstances where values may change for the current or past years after that.
