A corrected version of the counties list was added on September 11, 2023.

A detail of updates in August of 2023 and a preview of the upcoming counties in our pipeline is below. 

Parcel Schema Changes in October - We have extensive additional information on the fields below coming out over the next two months on our blog. Please see https://regrid.com/blog/schema-changes-2023 for a detailed discussion of these changes. A summary of the changes is below.

While the final names are still subject to change, these are the columns we will be adding to both our Standard and Premium datasets:

• state_parcelnumb - The parcel number used by the state
• account_number - The assessor/tax collector's account number associated with the parcel
• tax_id - The assessor/tax collector's tax id number
• census_zcta - The US Census Bureau's Zip Code Tabulation Area zip code 
• previous_owner - The previous parcel owner, seller or grantor where available
• numrooms - The number of rooms associated with the parcel as tracked by the assessor
• szip5 - The USPS 5 digit zip code

The following columns are being added to our Premium dataset only:

• Census_elementary_school_district - US Census listed elementary school district
• Census_secondary_school_district - US Census listed secondary school district

• census_unified_school_district - US Census listed unified school district

• Fema_flood_zone - FEMA Flood Zone Type
• Fema_flood_zone_subtype - FEMA Flood Zone Subtype
• Fema_flood_zone_data_date - The FEMA effective date of the flood zone data

We will be removing the following columns from both our Standard and Premium datasets. These columns were identified as redundant with other columns or being of low utility, and all have very low fill rates: 

• sourceagent
• multistruct
• subsurfown
• subowntype
• sourceref
• sourcedate

We will not be adding the previously mentioned brownfield and wetlands columns to our dataset at this time. A further review of the available source data for these two categories was not accurate enough to confidently join with our parcel data.

Changes to the "ll_stable_id" field - This field serves to indicate whether a Regrid "ll_uuid" was effectively transferred from the previous county data to the newly refreshed county data. Previously, it contained solely the term "preserved" if we successfully linked the refreshed parcel with its counterpart in our prior dataset, thereby keeping the "ll_uuid" unchanged. A null value denoted an inability to match the refreshed parcel with any previous parcel, leading us to generate a new "ll_uuid" for the refreshed parcel. This situation was most common with new parcels arising from parcel divisions, new subdivisions, and the like.

Moving forward, our approach will expand beyond using just "preserved." Instead, we will use an indicator of the method used to establish a connection between the refreshed parcel and its previous counterpart, utilizing one of the following descriptors: "parcel number", "address", or "geometry". While the "preserved" value will continue to exist within our data, these new indicators will progressively appear alongside it.

Coverage Report - Updated for this month and available here.

A machine-readable version of this list is included in the `verse` table available in all the formats above as well as CSV format for use in spreadsheets. To find the latest updates in verse, sort by 'last_refresh' and use the 'filename_stem' column to identify the file.

Based on feedback and county challenges, pipeline planning is always subject to change. As always, please contact us if you have any questions about accessing or using the data, if you find issues with any of our data, or you have any comments or questions about our data in specific areas or states. We also love to hear from you about which counties or regions you'd like to see us update next, as it helps inform our planning process.
