Can you rent by the room in Baltimore, MD?

Restricted. More than two separately-let rooms is a rooming house. The lease structure is the only lever.

Occupancy cap

TWO ROOMING UNITS is the practical line. Baltimore Building Code sec. 202.2.14: a "rooming house" is a building that "is not a multiple-family dwelling" and "contains more than 2 rooming units occupied or designed or intended to be occupied by individuals who, even though they might share common areas and facilities, do not form a single housekeeping unit and do not provide compensation under a single lease for occupancy of the rooming house." Separately, sec. 202.2.6 makes "any combination of 3 or more rooming units" a multiple-family dwelling. The zoning code's "family" is reported as up to four unrelated people forming a single housekeeping unit, plus up to two roomers - that part is SECONDARY-SOURCED and should be confirmed against Article 32 before you rely on it.

Is it a permitted use

THE DEFINITION HANDS YOU THE LEVER, THE SAME ONE AS BOSTON AND NEW YORK. A rooming house requires BOTH that the occupants do not form a single housekeeping unit AND that they do not pay "under a single lease." One joint lease over the whole house, with tenants who genuinely share the household, is not a rooming house on that text. Three or more separate per-room leases is one - and at three rooming units it is also a multiple-family dwelling, which a single-family certificate of occupancy will not carry.

Registration or licensing

A rooming house or multiple-family dwelling needs a use registration and a certificate of occupancy matching that class. Baltimore also runs a city-wide rental licensing and inspection programme covering essentially all non-owner-occupied residential rentals.

State pre-emption

Maryland does not broadly preempt local rental regulation; Baltimore is a home-rule city and regulates occupancy and licensing itself.

How to read this

Renting a house by the room is usually governed by three things: how many unrelated adults may share one dwelling, whether the arrangement is a permitted use or a boarding house, and whether the state has pre-empted the local rule. This page summarises the ordinance and cites it. It is research, not legal advice — a local land-use attorney decides whether a specific property complies.
