Frequently Asked Questions
Does Baltimore require a city business license for cleaning work?
Baltimore itself does not issue a general cleaning license, but Maryland may require a Trader's License through the Comptroller depending on how your business is classified, and that is separate from your Maryland SDAT entity registration. The fee varies by category. Check your specific classification at comptroller.maryland.gov rather than assuming, because the Trader's License requirement historically keys to selling goods and a service-only janitorial operation may fall outside it.
Are cleaning services subject to Maryland sales tax?
No. Maryland exempts cleaning services from its 6 percent sales tax, and because the state has no local sales tax add-ons, there is no jurisdiction-by-jurisdiction rate table to manage. That is a genuine administrative advantage over neighboring Virginia and DC. Supplies you sell to a client remain taxable at 6 percent, so keep those on their own invoice line.
When does Maryland prevailing wage apply to a cleaning contract?
On public works contracts above $500,000, where rates are set by the Maryland Commissioner of Labor and vary by county. For a cleaning contractor, the practical exposure is state-funded facilities: University System of Maryland campuses, state office buildings, and similar. The wage determination is not negotiable and it will change your labor cost materially against a private-sector bid, so pull the current cleaning classification rate for your county from MD Labor before you price the job, not after you win it.
What are the biggest institutional cleaning opportunities in Baltimore?
The hospital and university block dominates. Johns Hopkins Hospital and its university campuses, the University of Maryland Medical System, and the state government presence together account for an outsized share of the region's contracted square footage. These buyers run formal procurement, demand higher insurance limits than a commercial office would, and often require bloodborne pathogen and infection control training documentation for every worker on site. Building that compliance file is the barrier to entry, and it is also what keeps casual competitors out.
