Getting a Handle on Building Code

I’m a new owner of a 4-unit brownstone and trying to get a handle on the various rules and regs that I should be aware of – signs that need to posted, smoke/CO2 detectors in units, etc.

Is anyone of aware of a city guide that is available or a good web site the sums up these rules/regs/code?

Thanks in advance.
