Building Permits

Dataset

Description

Details changes made to a property based on building permits that specify a description of work and job value as submitted by an owner/contractor to a local authority such as the city or county.

Example

Usage

Property Valuation: Building permits provide insights into improvements being made on a property that may affect the value of a property.

Target Marketing: Companies marketing products and services to homeowners and renters can often identify target customers based on construction activity represented by a building permit. This includes repairs and maintenance that need to occur at a specific time after the original project was completed.

Sourcing

Building Permits are sourced from local government authorities such as counties. Most jurisdictions make this information available monthly to coincide with federal reporting by the US Census Department. ATTOM receives weekly updates of building permit data and these are usually applied to ATTOM Cloud on a Monday evening. The ClientProductProcessingStatus tables can be used to establish when the tables were last updated.

BuildingPermitStatus

Each local government authority will have a process for building permits. This will involve the building permit moving through various statuses (e.g. Received, Paid, Rejected). This table records the date on which a building permit is known to have entered a specific status.

The field EffectiveDate is used to establish when a building permit entered that status. The earliest value for EffectiveDate for any building permit is the best indicator of when a building permit was first filed.

Matching Data

ATTOM ID

There can be multiple Building Permit records for each property. The Building Permits can be connected with other Property data such as Addresses and Property Characteristics via the ATTOM ID.

Note: If ATTOM has been unable to match a Building Permit to a specific property, the ATTOM ID will be assigned as 999999999.

BuildingPermitID

Each building permit is uniquely identified via a Building Permit ID (BuildingPermitID) that is assigned to each building permit.
