Prince George’s County wrote the rule everyone else copied. The county has required fire sprinklers in new one- and two-family homes since 1992, the first large jurisdiction in the country to do it, and the results became the most cited numbers in residential fire protection: across the mandate’s first fifteen years, the county recorded 101 fire deaths in unsprinklered homes and zero in sprinklered ones. That record is a large part of why Maryland took the requirement statewide.
Being first has a practical consequence: this county holds the oldest large stock of home sprinkler systems anywhere, and systems from the 1990s are deep into the age where they need real attention. Heads from that era are long discontinued, some were part of a national recall in 2001 and were never swapped, valves seize, escutcheons crumble. The townhome belts of Bowie, Laurel and Upper Marlboro are full of systems past their thirtieth birthday, which makes repair and inspection work a bigger share of what we do here than in any other county.
Water follows the usual Maryland split. Most of the county sits on WSSC service, where systems connect to the street and stay in the standard price range. The rural south, Brandywine, Baden, Aquasco, Croom and the tobacco-country roads between, runs on wells, so new builds there carry the stored-water tank and booster pump. Permits file through DPIE with the building permit, and after three decades of 13D plans, nothing about a residential sprinkler drawing surprises the reviewers there.
Sprinkler plans file through the county’s Department of Permitting, Inspections and Enforcement (DPIE) alongside the building permit, under a Maryland State Fire Marshal fire protection license. DPIE has been reviewing residential sprinkler drawings longer than any office in Maryland.

Prince George's sprinkler questions, answered
How long has Prince George’s required home fire sprinklers?
Since 1992, first among the country’s large jurisdictions and twenty-four years before Maryland’s statewide mandate. Any house or townhome built in the county since then has a system, which by now describes a very large share of its housing.
Did the sprinkler mandate actually work?
The county’s own record over the mandate’s first fifteen years: 101 fire deaths in unsprinklered homes, zero in sprinklered ones. Those numbers get cited in fire-protection circles nationwide, and they are the backbone of the case that put the rule in state law.
My system is from the 1990s. Does it need to be replaced?
Usually not wholesale. Piping generally holds up; it is heads, valves and gaskets that age. The right move is an evaluation that identifies discontinued and recall-era heads, checks the valve, and lays out a repair list. Most 1990s systems come back to full service for far less than replacement.
What is this about recalled sprinkler heads?
A widely used family of residential heads from the 1990s was recalled nationally in 2001, and plenty were never exchanged. The model is stamped on the head, and identifying them is a standard part of our inspections in this county. Swapping them is routine work.
We are building in Brandywine on a well. What does that add?
The stored-water package: a 300 to 500 gallon tank and a booster pump, typically $3,000 to $6,000 on top of the per-square-foot price, drawn into the plans from the start. The well-water guide covers the details.
