Retrofitting existing house with sprinklers

[Nitin Gupta]

Hi folks, we are looking at potentially retrofitting an existing SFR with sprinklers in Seattle (city code might require for a new backyard build). Is there an order of magnitude we can use to estimate what it will cost us?

SFR is 2100 sqft over two floors (one is basement), both floors are fully-finished, water pressure is not an issue. there is no other rehab in the main house, so we will have to cut into the ceiling for just the retrofit.

Thanks a ton!
