Straight answers to fair questions.
Are fire sprinklers really required in new Maryland homes?
Yes, statewide, in every new one- and two-family dwelling since the start of 2016, with no county opt-out. Anne Arundel County got there earlier, requiring them since 2009, townhomes included, and its rule also covers rebuilds where more than half the home is reconstructed.
Will burnt toast set off my sprinklers?
No. Sprinkler heads respond to heat at the head, roughly 155 degrees, not to smoke. Cooking smoke, candles, and steamy showers do nothing to them. In a real fire, only the head over the fire opens; the whole-house Hollywood downpour is a myth.
What does a system cost?
New construction runs about $1.35 to $1.60 per sprinklered square foot on public water; retrofits run $2 to $7; well-fed systems add $3,000 to $6,000 for tank and pump. We publish the entire table with worked examples on the cost page, which no other Maryland sprinkler contractor does.
Who is allowed to install and service sprinkler systems in Maryland?
Contractors licensed by the Maryland State Fire Marshal for fire protection work. That license is the trust marker in this trade: ask any bidder for the number. Plumbers and handymen cannot lawfully do this work on their own credentials.
Do sprinklers freeze in Maryland winters?
Pipe in conditioned space does not. Runs through garages and attics need insulation or heat protection, and those are exactly where the freeze claims come from every January. If your system has runs in cold spaces, an annual check before winter is the cheap insurance.
Is there an insurance discount for having sprinklers?
Most carriers writing Maryland homes offer one, commonly 5 to 10 percent off the premium, and they may ask for documentation of a working system. Our inspection report satisfies that, and for many homes the discount funds the inspection.
A sprinkler head is dripping. What do I do first?
Close the sprinkler control valve, the one on the line with the pressure gauge near your meter or in the utility closet. That stops the water without shutting the house supply. Then call the county line on this site. Do not unscrew, plug, or tape the head.
What happens to my sprinklers when I sell the house?
The buyer’s inspector will note the system; a sprinkler-specific check answers whether it actually works, which a general inspection does not. Sellers do best commissioning it before listing. The county inspection pages cover the resale sequence.
