In the NEC 1999 & 2002, for a 3-family house, do we need one smoke detector in each dwelling bedroom? If YES, what about the NYC Building Code? Have they omit this out from the NEC Code?

The NEC doesn't regulate smoke detector installations. It is a Building/Housing Code issue.

Personally, out of common-sense, I'd fit one in every bedroom, it gives everyone a better chance of escaping, should a fire break out at night.

Last job I did that involved smokes was (1) in each bedroom, (1) in each hallway on each floor, and (1) rate-of-rise in furnace room; all linked for common alarm.

That community operated off the '99 or '02 NEC and BOCA, IIRC.

To keep it short here,
NY State requires that when any type of permit (building, plumbing, electrical, etc) is pulled for work inside a building, smokes will be required to be installed. Depending on the conditions, hardwired and interconnected smokes will be required.

So a plumber files for a bathroom toilet, and the building department flags the job - assesses the property and requires smokes if the smokes are not up to code.

I'm in CT, but I hear that NY has adopted the same one and two family dwelling codes as us. Smokes are required in each bedroom, outside of the bedroom area, and on each additional level (including the basement). In new construction, they must be AC-DC and interconnected. If any other remodel work is done, they must be added, but battery units only without interconnection is allowed.

Just to clarify, under the International Residential Code, battery only untits w/o interconnection are allowed in remodels, only if interior wall or celing finishes are not being removed, and if there is no attic, crawlspace, etc. available to allow AC power supply and interconnection w/o removing finishes.

Im in ct. I normaly install them in each bedrm, bottom of stairs, top of stairs, basment and furnace rm. I even try to do this on remodels a little more costly but make homeowners feel safe.
