Contractor licensing requirements in DC / Maryland

[Paul Gupta]

Hi, in California, For jobs requiring a license, there was CSLB (contractor state licensing board) which would give either a General Contractor license, or specialty licenses by trade (~60 specialties such as concrete, welding tile, ) https://www.cslb.ca.gov/about_us/library/licensing_classific...

My Q: does Maryland and DC area have similar requirements?  I see this - is it the right place, it has very few categories https://labor.maryland.gov/pq/

Grateful for opinions please.
