Md. Code, Natural Resources § 5-704

(a) Any individual or corporation that willfully, maliciously, or with intent, sets on fire, or causes to be set on fire, any woods, brush, grass, grain, or stubble is guilty of a misdemeanor and upon conviction is subject to a fine not less than $250 nor exceeding $2,000, or imprisonment for not less than 30 days nor exceeding five years, or both with costs imposed in the discretion of the court.

(b) An individual or corporation may not carelessly or negligently set on fire, or cause to be set on fire any woods, brush, grass, grain, or stubble.

The landowner from whose land the fire originated also is liable in a civil action for damages for injury resulting from the fire, and for the cost of fighting and extinguishing the fire, unless the landowner can prove to the satisfaction of the court before which the case is tried that the injury complained of was suffered without any negligence on the part of the owner or the owner’s agents.

(c) Any person who discovers a forest or brush fire not under the control of some person shall extinguish it or report it to the local fire warden.

(d) The provisions of this section do not contravene other provisions of law relating to the liability for fires of railroad companies.
