Permits are pulled before work begins and then
inspected by the county. A contractor who files them is working
inside a system with an inspector in it, which is what unpermitted
work avoids.

Our records for this
contractor's counties begin August 2021. Years
before that are not shown because we hold nothing for them, not
because nothing happened.
What this page is, and is not
- Howard County: 20 permits observed, from records beginning August 2021.
- Anne Arundel County: 13 permits observed, from records beginning December 2025.
This page shows permits we observed in county records.
Our observation is not complete: work done before those dates, in
counties we do not cover, or on filings that name no contractor does
not appear here. A contractor's real work is almost always
greater than what we observed, and absence of a permit on this page
does not mean the work was not done or not permitted.
We currently hold records for
Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Frederick County, Howard County, Prince George's County, and Washington DC; see permit
coverage for what that includes.
Common questions
- Does a permit record mean this contractor is licensed?
- County permit records list A.J. MICHAELS COMPANY, INC under
Maryland HVACR Contractor, Licensed Electrician, Master Plumber and Gas Fitter, Maryland State Electrician.
Check current standing with the issuing body before hiring.
- Why do some contractors show more permits than others?
- Counties began publishing at different times and describe
contractors differently, so the number reflects what we observed
as much as what the contractor did. It is not a ranking.
- What should I still ask for?
- Proof of insurance, a written contract, and the license number
for the trade being performed. A permit record is a starting
point, not a substitute for either.
