We're excited to provide you USPS vacancy data nationwide at the parcel level, something that to our knowledge has not been done before. While aggregated USPS vacancy data is a widely-accepted indicator and has been used in academic studies and research since at least 2010, there has rarely been a way to crack that data open and see how those aggregations have been made, or how reliable the data is. We are able to offer this information right at the parcel level for granular insights.

To get access to this amazing data you'll want to license our premium dataset in bulk, or sign up for one of our SaaS subscriptions. Contact us at sales@regrid.com if you have further questions or are interested in a quote.

This data is available as part of our Premium dataset, available nationwide or in smaller geographies. Interested? View our bulk data options.

Vacancy Data for the city of Detroit, 2020

Get our vacancy & residential indicators as part of our premium data package along with our other premium derivative fields via bulk data, API, Regrid Pro, Regrid Team & Regrid Enterprise subscriptions.

Premium data includes nationwide parcel boundaries with all standard attributes, plus a variety of fields we append to the data from other sources such as:

• Standardized land-use codes
• Nationwide building footprint counts and building footprint square footage
• Nationwide United States Postal Service-validated address data with uniform residential property indicator and vacancy information

The United States Postal Service maintains a database of every deliverable address in the US.

This data is collected and maintained by their letter carriers.

As part of their regular processes, letter carriers identify addresses as either primarily residential or non-residential delivery points. That information is recorded as what the USPS calls their "Residential Delivery Indicator" (RDI).

There are times when the letter carriers record addresses that are valid addresses, but for some reason are not currently collecting their mail. This is recorded as a "Vacant Flag". It is important to understand these addresses could receive mail, but are not currently receiving mail. This is different from addresses that are not considered valid for receiving mail, for example addresses that might be assigned to new developments where buildings have not been built or are not yet occupied.

• ~89 million parcels currently have USPS data attached.
• We have ~117 million addresses in our dataset and we have matched approximately 89 million of those addresses for a total match rate of 76%.
• As this is our initial pass over the parcel addresses in our dataset, we expect to increase this number on subsequent passes over our dataset.
• Additionally, counties typically only maintain 1 address per parcel and a significant percentage of those parcel addresses are non-deliverable parcels like farm fields or other vacant lands.

• USPS data will be updated approximately every month as and when it is released by the USPS Certified Data Vendor we work with. 

• The USPS data is only available in our dataset where we have parcel address data, which is not the entire dataset. As a result, there will be a few places that may not have the USPS data.
• We currently don’t have buildings and unit-level USPS data. We typically only have one unit per building, even if it's an apartment building so mileage on the USPS data may vary in high-density areas. So as a result, the vacancy indicator may apply to one or a few units within an otherwise occupied multi-unit dwelling.
• We have integrated this data as-is into our dataset. USPS data itself can vary in accuracy. So please be aware that there might be some discrepancies with this data occasionally.
• USPS data is updated every month and we will do the same. The data may be inaccurate between updates due to changes in occupancy or demolitions that will not be reflected until the next data refresh.
• We will be working to ground truth and improve the accuracy of this data moving forward. If you have observations about the USPS data in your area which you'd like to share with us in an effort to refine and improve the information, please get in touch by emailing help@regrid.com or via the help widget on our site.
  
  While we know that the data is not perfect - and we hope that you get in touch with us to share your findings, so we can refine this dataset going forward - the Loveland team feels that this is an important tool for our friends and partners to have, and a revolutionary step forward in understanding the property dynamics in our communities.

• This data is available with our paid mapping subscriptions (Pro and Team) and are contained in our Premium dataset for those interested in getting access via licensing bulk data or our API. Please contact us to get a quote & a data sample.
• We request our customers not to use the data for direct mail commercial marketing campaigns.
• Pro users can view, filter & style the USPS fields. However, Pro users will not be able to download the USPS data in any format. Team customers can view & export up to 50K rows of USPS data as a CSV.
