Our jurisdiction requires a sprinkler to either be maintained or removed if it is not a requirement...
Some jurisdictions do not allow a change that reduces the current level of protection.
To the best of my understanding, the previous comment is correct. An installed automatic fire sprinkler system shall be maintained or removed if it is not required. In order to be removed, you should get authorization from the local authority having jurisdiction. For the City of St. Louis you have to submit a formal request explaining the circumstances for allowance for removal.
In general, you cannot give a false representation of an active sprinkler system. The sprinklers should be removed and system tagged appropriately as an inactive system or system removed in it's entirety.
I agree with Henry. My big question is what codes do you adopt and why isn't the new tenant/business required to be sprinklered.
Since the new occupancy classification doesn't require a fire sprinkler system, the existing system can be demolished.
Just curious....what use group was the residential building changed to?
Agree with all of the above comments - Either make the system in compliance with current requirements or remove the formerly compliant system.
when you say not required have you checked all possibilities?
For instance if you have the ICC codes (International building code) adopted do you need a fire sprinkler system for the height and/or area?
As per NFPA 13, 2019, 29.2.2
Where all or part of an inactive sprinkler system is abandoned in place, components including sprinklers, hose valves and hoses, and alarm devices shall be removed.
Control valves abandoned in place shall have the operating mechanisms removed.
Sprinkler system piping and/or valves abandoned in place shall be uniquely identified to differentiate them from active system piping and valves.
