Why the First Five Minutes Decide the Margin
Every fire alarm contractor has a version of this story: the job that was quoted as a straightforward install and turned into an LPC approval, a high-rise requirement nobody priced, or an open DOB job from a contractor who vanished in 2019. None of those surprises live on site. All of them live in city records — visible before you ever pick up the phone to say a number.
Here are the seven checks, in the order they pay off.
The 7 Checks
Check 1
BIN, Block & Lot
- Confirm the exact structure — corner lots and multi-building sites often carry several BINs, and quoting against the wrong one poisons everything downstream.
- Every DOB and FDNY record you will ever pull for this job hangs off these identifiers. Get them first.
Check 2
Occupancy Group & Building Class
- The occupancy classification drives which systems the code requires — and what your filing will be measured against.
- If what the records say does not match what the caller describes ("it is offices now, it used to be a warehouse"), that gap is scope, cost, and possibly a change-of-occupancy conversation. Price it, do not discover it.
Check 3
Construction Type, Stories & Height
- Height and story count determine whether you are in high-rise territory, where fire alarm requirements — and your scope — change dramatically.
- Construction type previews the wiring reality: fishing cable through fireproof construction is not the same day rate as a joisted walk-up.
Check 4
Year Built & Landmark Status
- A designated landmark can mean Landmarks Preservation Commission review before you touch protected fabric — approvals and calendar time your quote must carry.
- Pre-war buildings hide surprises: abandoned risers, plaster over everything, and "existing conditions" that are in nobody's drawings.
Check 5
DOB Job History
- Has fire alarm work been filed on this building before? By whom, and when? That is your baseline for repair-vs-alteration-vs-new conversations.
- Open jobs from other contractors still attached to the building are the reddest of flags — they can block or complicate your filing.
Check 6
Elevator Devices
- Every registered elevator is a recall interface in your scope. Knowing the count before the walkthrough means the walkthrough confirms instead of surprises.
Check 7
Flood Zone
- Flood zone designation affects where equipment can live — a panel location that works in a dry-land building may need rethinking (and re-pricing) in a flood zone.
What Each Finding Changes in the Quote
The checks are not trivia — each one maps to a line item or a risk:
- Occupancy and height set the system scope: what the code demands is the floor of your price, not the ceiling.
- Landmark and LPC involvement add approval time — quote the calendar, not just the labor.
- Job history tells you whether you are filing fresh, altering an approved system, or untangling someone else's unfinished work — three very different projects that get quoted as one by contractors who did not look.
- Elevators and construction type size the labor: interfaces to build, walls to fish.
RED FLAGS WORTH A PAUSE
Open DOB jobs from another fire alarm contractor · occupancy on record that does not match the use you are told about · no fire alarm filing history on a building that clearly has a system (see what to do when no approval exists). Any of these deserves a conversation with the client before a number leaves your mouth.

The Building Identification Number lives in NYC DOB records. You can dig it out of BIS or DOB NOW, or type the address into a property lookup tool and get the BIN, block/lot, and full building profile in one search. Corner lots and multi-building sites often carry several BINs, so confirm you have the one for the exact structure.
Work on a designated landmark can require Landmarks Preservation Commission review before elements that touch protected fabric are altered. That adds approvals and calendar time that a quote assuming a standard install will not survive.
Three things that change your price: whether fire alarm work was filed before (and by whom), whether open jobs from other contractors are still attached to the building, and whether stalled or never-closed filings exist that a new project could inherit as complications.
Yes. Fire PDF Pro's NYC property lookup returns the BIN, block/lot, occupancy group, building class, construction type, stories, year built, landmark status, flood zone, DOB job history, and registered elevator devices from a single address search — free for registered users.
