Our data


What the "Permits" data type includes

  • the type and description of the work for which the permit was issued
  • the estimated cost of the work performed
  • the type of real estate that will be undergoing work
  • the address of the property undergoing work
  • permit status
  • the date the permit was issued/renewed/expired
  • participants related to the permit process (property owners, contractors, agents, etc.)
  • and more…

Historical data

Donuka collects, stores, and displays not only current but also historical data collected over the past 10 years or more.

As a result, our users are able to track the history of any (even the most insignificant) changes and updates to a permit from the moment the permit is applied for up to the moment the work the permit was issued for is completed.

Data sources

Donuka strives to provide credible information obtained from reliable sources. That's why we only collect and process data from the following sources:

  • city administrations
  • district administrations
  • state administrations
  • federal agencies
  • and others like them…

In all, we collect data on permits to perform various types of work on real estate properties from over 4,000 different government sources.

Data update frequency

Permit registries are maintained separately by city, county, state, and federal agencies. These add up to thousands of different registries and, respectively, thousands of different data sources, all operating independently of each other.

Each city, county, or state administration decides for itself how often to update and publish information. Some make changes and publish updated data several times a day, some daily, some weekly, and some just once a year.

Within 1-2 days of the publication of data in a city, county, or state administration's database, Donuka updates the data in its own database, and it then becomes available to our users.

Searching for real estate by permits

Donuka allows you to perform a detailed search for the properties using 15+ parameters related to permits.

In just a minute, you can sift through 100+ million real estate properties to find only the ones that are right for you.

Here's an example of a search query using permit parameters:

  • date permit was obtained: <7 days
  • type of work: installation of windows
  • estimated cost of work: >5,000 USD
  • address of the property undergoing work: Florida

In your search results, you will instantly receive a list of properties that match all of the above search parameters. You can also use search options for other types of data to get the most accurate results.

Tracking changes in permits

Donuka allows you to create tasks that track changes in existing properties and alert you to new properties that meet the values you specify.

Here's an example of tracking permits for an existing property:

  • new permit: yes

You'll receive an instant notification by email and on your dashboard if a property you're tracking has a new permit to perform any type of work.

Here's an example of tracking permits for new properties (or existing properties with characteristics that correspond to your specified values):

  • type of work: laying down flooring
  • estimated cost of work: >3,000 USD
  • address of the property undergoing work: Houston, College Station, Beaumont

You'll receive an instant notification by email and on your dashboard with a list of properties that have obtained permits matching your specified values.
