Data notes
Why is one company listed many times?
The companies listed here are extracted from the City of Chicago building permits data in which there are several spelling differences.
How should I interpret estimated costs?
The building permit applicant provides the estimated cost value and it's not vetted by DOB. We use the estimated cost for sorting and for grouping permits into cost buckets. It should not be taken too literally.
Where can I check if a contractor has an active license?
Search for a contractor name on the city's official database of licensed contractors, which is updated daily.
