Sprinkler and smoke detector in office in new toilets

[CGH]

Existing building is a 3 story fully sprinklered with automatic and manual fire alarm system with CO detection. Construction Classification is Type IIB with a occupancy work area. Using EBCNYS alteration level 2, architect proposes to turn office space into two 7ft x 10ft toilet rooms in a business tenant office space. Do the new toilet rooms have to be sprinklered and/or do they also require alarm initiating devices and alarm notification appliances? EBCNYS Section 703.1 require that alterations be done in a manner that maintains the level of fire protection provided. Section 903.3.1.1 of BCNYS refers to bathroom coverage in Group R. I don't see any sections on omitting sprinkler heads in toilets of occupancy. Having more than a smoke detector seems like overkill. Please provide code section that supports your response. Thanks.

If the building is sprinklered, then the sprinkler system has to be maintained operable in accordance with NFPA 13 which is throughout the building which would include the new bathroom spaces...

I would think sprinklers would be required in bathrooms, people still smoke even when you tell them to read the no-smoking sign!

Even the janitors closet would need a sprinkler head it would think.

There are almost no exceptions for spaces to be sprinklered in a NFPA 13 system.

Restrooms don't require fire alarm initiating devices, but do require audio/visual notification.

The NFPA 13 (Standard for the Installation of Sprinkler Systems) requires sprinklers in restrooms, and the International Building Code (IBC) may have comparable requirements.

The IBC defers to NFPA 13 for the design of a sprinkler system.
