Summary
Montgomery County requires a fire sprinkler system in every dwelling unit and attached accessory structure before the County will issue a building permit for new or reconstructed residential buildings, per County Code Section 8-29A.
The County must not issue a building permit for the construction or reconstruction of any residential building unless the plans include the installation in each dwelling unit and any attached accessory structure of a fire sprinkler system.
(c) The County Executive must issue regulations to implement this Section. The regulations may authorize the Director to approve the use of specific construction alternatives that provide equivalent or greater protection of the public in residential buildings in which fire sprinkler systems will be installed.
(d) After inspection and final approval of a fire sprinkler system required under this Section, the inspector must provide to the initial occupant of the dwelling unit written information approved by the Fire Administrator about the proper care and maintenance of a residential fire sprinkler system. If the dwelling unit has never been occupied, the builder or other current owner must not accept payment or rent for the unit until the inspector has transmitted this fire sprinkler information to the initial occupant. The Fire Administrator must make the information widely available to residents who purchase or lease a previously occupied unit with an installed fire sprinkler system, and other County residents.

Full Breakdown
Section 8-29A bars the County from issuing a building permit for construction or reconstruction of any residential building unless the plans include a fire sprinkler system in each dwelling unit and any attached accessory structure. The Director of Fire and Rescue Services approves the equipment, which must meet current National Fire Protection Association standards. After a sprinkler system passes final inspection, the inspector must give the first occupant written care-and-maintenance information, and a builder cannot accept rent or payment for an unoccupied unit until that information is delivered. Rockville, Gaithersburg and Takoma Park enforce their own building codes and administer this requirement separately, not under this section.
Violations & Fines
Plans that omit the required sprinkler system are grounds for the Department of Permitting Services to refuse the building permit outright; occupying or renting a unit before the mandated sprinkler-care disclosure is delivered also violates Section 8-29A(d).
