New-construction fire sprinklers in Montgomery County, Maryland.

Montgomery new construction splits into two markets and we work both. Down-county it is teardown rebuilds and infill on WSSC service, where the sprinkler questions are meter sizing and making the system disappear into a house full of expensive finishes. Buyers there expect concealed heads behind flat cover plates, and a 13D plan delivers that cleanly when it is drawn in from the start rather than negotiated after drywall. Up-county and in the agricultural reserve it is custom homes on wells, where the tank and booster pump need a spot in the mechanical room and a line on the budget before excavation.
Plans go to the Department of Permitting Services with the rest of the permit set. DPS reviewers have been reading residential sprinkler drawings for two decades, so a complete submittal moves and a partial one waits its turn twice. We seal the drawings, settle the WSSC meter question before filing, coordinate rough-in with your framer and plumber, and run the acceptance test with the inspector. Pricing follows the published table on the cost page, the same for a Potomac custom as for everywhere else we work.
Pricing for every configuration is published on our cost guide, well-fed systems are covered on the well-water page, and the county overview lives on the Montgomery County page.
Questions we hear on this work
Can the sprinkler heads be hidden in a finished ceiling?
Yes. Concealed residential heads sit behind a flat cover plate that matches the ceiling and drops away at temperature. They cost a bit more per head and are the default in high-end Montgomery builds. Specify them at design time; swapping exposed heads for concealed ones later is needless money.
Our teardown lot has old water service. Can the sprinklers use it?
Sometimes. Sprinkler demand often exceeds what an aging service line and small meter can deliver, and then the project needs a service upgrade through WSSC. That is a design-stage discovery when things go well and a framing-stage crisis when they do not, so we check it before sealing drawings.
How does the sprinkler plan affect the DPS timeline?
Filed with the first submittal it adds essentially nothing, because the review runs alongside everything else. Filed as a later revision it costs a full review cycle. Our drawings turn around in days, so there is no reason to file without them.
Who handles sprinklers in an addition?
The same licensed trade that installs full systems. An addition on a sprinklered home extends the existing system, and an addition on an older unsprinklered home generally does not force a whole-house retrofit, though very large projects are worth confirming. Either way, get the answer before the permit.
