How Do You Respond to an FDNY Plan Exam Objection?

An FDNY plan exam objection is answered by correcting each item on the objection letter, writing a response that answers every item by number, and resubmitting the revised sealed documents on FDNY Business, which is free within six months of the Letter of Deficiency. The Fire Department of the City of New York (FDNY) issues the objection when its plan examiner finds that a fire alarm, in-building auxiliary radio communication system (ARCS), non-water suppression or other FDNY-reviewed submission does not yet show compliance. Under the 2022 New York City Fire Code (FC) Section 105.4, those design documents run on the same clocks as permit applications: FDNY must act within 40 calendar days of each complete submission (FC 105.2.4), and an application not diligently pursued is deemed abandoned 180 calendar days after filing (FC 105.2.3).

An objection is a request for revision, not a rejection of the project. Most objections trace to a small set of document problems that FDNY itself has published, and a specific, complete response gives the examiner what is needed to accept the plans in the next round. This article covers what the objection means, the causes FDNY lists, the response step by step, the deadlines and how to avoid objections on the next filing.

What Does an FDNY Plan Exam Objection Mean?

An FDNY plan exam objection is the plan examiner’s written finding that a submission cannot be accepted as filed. On FDNY Business, the City’s online filing portal, a fire alarm application comes back with one of four results, and an objection is the second of them. The table lists the four results and what each requires next.

Results as listed on the NYC Business fire alarm application page, as of November 2026. FDNY engineering applications can also end in a Conditional Letter of Acceptance, a Letter of No Objection or a Site Visit Request.

FDNY reviews these documents because Local Law 195 of 2018 moved review of fire alarm, emergency alarm, ARCS, fire protection plan and non-water extinguishing system documents, including commercial cooking systems, from the Department of Buildings (DOB) to FDNY for filings from June 2, 2019. The filing form is the TM-1, FDNY’s application for plan examination and document review. Sprinkler and standpipe work stays with DOB, so an objection on a sprinkler filing is a DOB objection handled under DOB’s process; DGA’s guide to how fire protection plan review works at NYC DOB covers that side, and the split between the two agencies is laid out in DOB or FDNY: who approves what in New York City.

The legal footing for the objection is FC 105.4. Design and installation documents that FDNY must review are checked for compliance with the Fire Code, its rules and the construction codes, and FC 105.4.4 has the department approve, deny or preliminarily deny them on the FC 105.2.4 timetable. For fire alarm work the design standard behind most objections is 2022 NYC Building Code (BC) Section 907, which requires design and installation to National Fire Protection Association (NFPA) 72, the National Fire Alarm and Signaling Code, 2016 edition, as modified by Appendix Q of the Building Code.

What Causes Most FDNY Plan Exam Objections?

FDNY published its own list of the errors that draw objections. Its October 2020 guide, Tips for Successful Approval of a Fire Alarm System in NYC, includes a section titled How To Avoid Fire Alarm Plan Review Objections, and most items in it concern documents rather than engineering. The table groups the recurring causes, how each shows up on the objection letter, and the fix.

Causes summarized from FDNY’s Tips for Successful Approval of a Fire Alarm System in NYC (10/2020), section How To Avoid Fire Alarm Plan Review Objections. The guide states that it does not cover every filing requirement.

FDNY’s plan review items fall into three groups. Occupancy documents come first because FDNY reviews the fire alarm against the legal use of the building, so a plan that does not match the CO cannot be checked. Internal disagreement within the set is the second group, and missing supporting approvals the third. The guide’s separate list, General Tips to Avoid Defects, covers inspection items such as fan shutdown and elevator recall on alarm, but most plan review items concern documents.

How to Respond to an FDNY Objection, Step by Step

The response to an FDNY objection works best as one complete package. FDNY’s guide says to address every objection before resubmitting, and to contact the plan examiner first where the design team disagrees with one. The steps below follow that order.

1. Read the whole letter and number every item. Note the issue date on the Letter of Deficiency, since the six-month free resubmission window runs from it, and record the plan examiner’s name and phone number, which FDNY prints on fire alarm objection letters.
2. Sort each item: comply, clarify or contest. Many items are straight corrections. Some ask for information already in the set, and a few ask for something the design team believes the code does not require. The decision tree below shows how to sort them.
3. Call the plan examiner on any item in dispute. A short call before resubmitting settles misreadings and confirms what the examiner needs, which lowers the risk of a second objection on the same item.
4. Revise the drawings and cloud every change. Revised fire alarm plans are resealed and signed by the New York State registered design professional, with revision clouds and a revision number so the examiner can find each change.
5. Write the response matrix. List every objection by number with the response and the sheet revised (example below), and send it as the cover or transmittal letter that explains the revised sections.
6. Assemble the supporting documents. Add whatever the objections asked for: CO or Schedule A, DOB LNO, prior Letter of Approval, variance letter, CCD1, DEP asbestos form or landmark approval, plus a new signed TM-1 if the job description changed.
7. Resubmit on FDNY Business. Upload the revised plans, the response letter and the supporting documents inside the six-month window.

The response matrix carries the whole response in one page. The example below shows the format for a hypothetical tenant fit-out filing; the objection numbers and sheet numbers are placeholders.

The filing steps that come before the objection, and the Project Authorization and inspection that come after acceptance, are covered in DGA’s guide to how FDNY TM-1 fire alarm filing works.

Can an FDNY Objection Be Appealed?

An FDNY objection can be contested, but the routes are formal and slower than a revised drawing. The first route is the plan examiner: FDNY’s own guidance is to call the examiner on any item in dispute, and the call can settle a misreading once the examiner sees the sheet or the code section the design relies on.

The second route is a modification. Under FC 104.8, the fire commissioner may waive or modify a Fire Code provision where unusual conditions make full compliance impracticable, on a written request that states the grounds, and FC 104.9 lets the commissioner approve an alternative device, equipment or system that is at least equivalent. On FDNY Business a Fire Code modification is filed as a Fire Code Modification (Variance), which FDNY limits to the Fire Code and its rules; fire alarm and ARCS relief is requested as a Fire Alarm Variance on Form TM-4, and a Building Code departure that needs DOB approval goes to DOB as a CCD1. A modification request does not stay enforcement of the provision while it is pending (FC 104.8.1.3).

The third route is the Board of Standards and Appeals (BSA). New York City Charter Section 666 gives the BSA authority to hear appeals from any order, requirement, decision or determination of the fire commissioner. A BSA appeal is a separate proceeding with its own filing and schedule, so it suits a final denial on a point of real consequence, not a routine objection.

What Are the Deadlines, and What Happens If the Application Lapses?

Two sets of deadlines apply to an FDNY objection. The first is FDNY’s fee rule: the NYC Business application pages say resubmission is free within six months of the Letter of Deficiency, a new filing fee may be required after six months, and FDNY’s engineering application page treats the application as abandoned after that point. As of November 2026 the plan examination fee is $420 per application.

The second set comes from the Fire Code. FC 105.4 applies FC 105.2.3 and 105.2.4 to design and installation documents. FC 105.2.3 deems an application abandoned 180 calendar days after filing unless it has been diligently pursued or an approval has been issued, and the commissioner may grant extensions of up to 90 calendar days each for reasonable cause. FC 105.2.4 requires the department to approve, or to deny or preliminarily deny with written grounds, within 40 calendar days of each submission, and lets the commissioner extend the approval period once by 40 days for good cause.

An application that lapses costs more than a fee. FC 105.4.3 makes it unlawful to install, alter or remove a system whose documents FDNY must review before those documents are approved, so work cannot start on an unanswered objection. Without the Letter of Acceptance there is no Project Authorization, no inspection and no FDNY Letter of Approval, and DOB’s certificate of occupancy worksheet lists FDNY fire alarm approval among its required items. For a schedule estimate that includes review rounds, DGA’s Fire Protection Project Timeline Estimator gives a starting range.

A plan exam objection is also different from a Notice of Defect. The objection comes before work is authorized and concerns the documents; a Notice of Defect, formerly called a Letter of Defect, comes after a failed inspection and concerns the installed system. DGA’s article on what an FDNY Letter of Defect is and how it is cleared covers that later stage.

How to Prevent FDNY Objections on the Next Filing

Preventing FDNY objections starts with the occupancy documents. Before the drawings are finished, the design team should have the CO or approved Schedule A in hand, match the floor designations to it, and, where the building has no CO, obtain the DOB LNO early, since it comes from a separate DOB process.

The second habit is a self-check against FDNY’s published list. A reviewer who did not draw the set should compare riser counts with each floor plan, confirm that every symbol appears in the legend, read the input/output matrix against the actual sequence of operation, and check that the TM-1 job description matches the drawings word for word.

The third habit is to put every approval the design relies on into the set: the existing system’s Letter of Approval, any FDNY variance letter, any DOB CCD1, and the asbestos and landmark documents that apply. An examiner who cannot see an approval has to object to the condition it covers.

The fourth habit is to file R-2 residential fire alarm work separately from other occupancy groups and, where the fire alarm was approved at DOB on a PW-1 before Local Law 195 moved review to FDNY, to open a DOB Post-Approval Amendment (PAA) before filing an FDNY amendment. Both points appear in FDNY’s guidance and both produce objections that have nothing to do with the design itself.
