Q: What are the requirements for Women's Toilet Rooms in Places of Assembly? How many additional fixtures are required for Women?

A: See Local Law 57/2005 for full details. The Plumbing Fixture Count has been amended so that the requirement for the number of Womens's Toilets serving most Places of Assembly is generally twice that of Men.

What information is required on a Final Survey?

Q: What information is required on a Final Survey?

A: A Final Survey is required by the NYC Department of Buildings as part of the Final Certificate of Occupancy process. Final Surveys are required for New Buildings and for vertical or horisontal building additions. They may be waived by the Commissioner for small structures (see Code Section below). The Final Survey must be prepared, signed & sealed by a Licensed Land Surveyor. It must be reviewed and certified by the New Building Architect or Engineer of Record.

The purpose of the Final Survey is to ensure that the building complies with bulk regulations (since this cannot be done by the DOB Inspector at the site), does not encroach onto adjacent property lines, has proper grading at the sidewalk, has proper storm drainage, has the required amount of street trees, etc.

The NYC Building Code specifies the plan requirements for Final Surveys in BC Section
§ 27-219, excerpted below:

"27-219 Applications for Certificates of Cccupancy:

All applications for Certificates of Occupancy shall be submitted on forms furnished by the department. Each application shall be accompanied by an accurate and complete lot survey made by a licensed surveyor showing the location of any new building and/or any extension to an existing building, the elevation of the first tier of beams or the first floor, the finished grades of all open spaces on the lot, the location and controlling grades of watercourses, paved swales and similar above grade methods of storm water disposal when permitted by this code, the locations of all catch basins on the property, the established curb level, and the location of all other structures and impervious surfaces, as defined in subdivision (a) of section P110.2 of reference standard RS-16, on the lot. Such lot survey shall also show the location and boundaries of the lot or plot upon which such buildings and structures are located. The commissioner may waive the requirement of such survey in the case of small sheds, stands, signs, and similar small structures. In addition, prior to the issuance of a certificate of occupancy the department shall confirm by inspection that all work relating to the installation of the part of the storm water drainage system which shall lie outside of such property, if and as required by section 24-526 of this code, has been satisfactorily completed."

My Professionally Certified Application was Audited!

Q: I filed my application as Professionally Certified. The Application was Audited and Objections were issued. What is the process to resolve? Or, my Work Permits were already revoked & I need them to be reinstated.

A: If Audit Objections were issued, they will need to be addressed or the Work Permits could be revoked by DOB. If the Permits have already been revoked, but you are able to demonstrate that the Objections can be removed (eg: you have obtained a Reconsideration that addresses the Objections), the following procedure is to be followed, per DOB reg's:

1. Prepare a Post Approval Amendment (PAA) PW-1 (an original and two copies). In the comments section, state "This PAA is filed to answer the Audit Objections". If amended drawings are involved also list them in Section #16. FOR A REVOKED APPLICATION, a PAA to Reinstate the application must also be filed and the required fees paid.

2. See the DOB Audit Examiner with the PAA. The Audit Examiner will note on the PW-1 that it is OK to Lift the Hold so that the document can be entered.

3. Go to the Borough Commissioner's Office ahd have them lift the Hold on the application. This will enable the applicant or Filing Rep to enter the PAA Document. Make sure a copy of this document is put in the DOB Job Folder.

4. Bring a copy of the PAA to the Borough Manager's Office so that the PAA Document can be entered.

5. When all of the above items are completed, and the PAA Document has been entered in BIS, make an appointment with the DOB Audit Examiner so that the document that was originally audited and the PAA to answer the Audit Objections can be ACCEPTED in the Computer.

6. The Auditor will then take the DOB Folder to the Borough Commissioner;'s Office and they will send out a LETTER OF RECISSION, signifying that the Audit has been lifted.

Are Exit Signs Required in Residential Apartment Buildings?

Q: Are Exit Signs required at each floor in Residential Apartment Buildings or One-or Two-Family Residences?

A: No. Per BC Section 27-383, the Code makes an exception in the Exit Sign Requirement for Apartment Buildings (J-2) and One- or Two-Family Residences. Exit Signs are not required at each floor in J-2 or J-3 Buildings. See below Code Section:
"§27-383 REQUIREMENTS. Except in occupancy groups J-2 and J-3, the location of every exit on every floor and every opening from a room classified in occupancy group J-1 and containing cubicles shall be clearly indicated by exit signs. Such signs shall be placed at an angle with the exit opening if such placement is required for the signs to serve their purpose. In long corridors, in open floor areas, and in all other situations where the location of the exit may not be readily visible or understood, directional signs shall be provided to serve as guides from all portions of the corridor or floor."

What is little E? Is it near Little Italy?

Q: What is the little 'E' Designation on the Zoning Map? What is required?

A: In addition to Little Italy, NYC also has places called 'little E'. But it's not a hip new neighborhood. It is a site where industrial contaminants may exist.

"The E Designation is applied to certain properties that have been re-zoned, where the projected use may lead to increased environmental risk, as when a site zoned for manufacturing is re-zoned to residential use. Developers, owners and tenants on such sites may have to do environmental investigation before they can get their construction plans approved. In some cases, remediation (cleanup) may also be required and/or special measures built into the project to protect occupants or construction workers against environmental hazards. At the very least, this means delay. It can also result in added cost" - Joseph Horowitz, PE

Carbon Monoxide Detector Affidavits

Q: I am processing Certificate of Occupancy issuance for a building, and have been asked to provide a Carbon Monoxide Detector Affidavit by DOB. When is this required by Code? What is the Law for Carbon Monoxide Detectors? Where can I find more information?

Temporary Place of Assembly Permits

Q: What is the procedure to obtain a Temporary Place of Assembly Permit (TPA)? What are the submission requirements?

A: Check out TPPN 7/96, which outlines the submission requirements. TPA's should be filed at least 10 business days prior to the TPA event. TPA's are required where a space does not have a PA Permit and event is planned for the space which exceeds 75 persons. A TPA Permit is also required where an existing Place of Assembly will be occupied in a special way (eg: more Occupants that that which is approved) for a one day event.

The DOB fee for submission (as of 1/2005) is $250, plus a $100 late fee for each day less than 10 days prior to the event.

What are "Air Rights"? How does it work?

Q: What are Air Rights? How do I know if Air Rights are available? What does that mean?

A: "Air Rights" is the term used when a Building Owner sells/transfers his unbuilt Zoning Floor Area to another Building Owner or Developer. This may happen, for instance, where a Landmarked structure, such as a Church, is located in a high-density Residential or Commercial District. The Church could be located in a Zoning District with an FAR of 10, but might only be using a fraction of this. They could sell their unbuilt Zoning Floor Area to an adjacent Owner/Developer. This would constitute an "Air Rights Transfer" or "Zoning Floor Area Transfer". The Church benefits because they receive compensation for the sale of Potential or Unrealized Real Estate. The Developer benefits because they can then incorporate this additional Zoning Floor Area into their building.

Most Commonly, the Development Lot and the Underbuilt Lot are adjacent to one another. The Tax Lots are declared to be a single Zoning Lot. This would be formalized as an agreement, and filed with the County Clerk's Office, similar to a Deed. Thus, an Air Rights Transfer or Zon ing Lot Agreement of this type should be retrievable by a Title Search or an in -house ACRIS search of Department of Finance records.

In addition, when properly done, a statement will be found on the Certificate of Occupancy stating "This Zoning Lot is comprised of Tax Lots (1), (2), and (3)", signifying that multiple Tax Lots are being treated jointly as one Zoning Lot for a Zoning benefit.

Do Flags and Banners Require Work Permits?

Q: Is DOB Approval required to hang a banner or a flag on an existing or new flagpole? How are flags and banners treated?

A: A flag or banner is a Sign, and requires a DOB Sign application and compliance with the non-illuminated sign provisions of Zoning. If both sides of the flag are identical, then the area does not need to be counted twice. If a new Flagpole is proposed, this shall be filed under a separate application from the Sign, with structural connection details. Flagpoles may project across the front property line up to 2' within the curb, and shall be a minimum of 15' above the street level. Flags on Community Facility buldings which represent such facility are permitted without area limitation.

Demolition or Alteration Permit?

Q: I want to demolish a portion of my building. Do I need a Demolition Permit? Do I need to file with the BEST Squad?

A:It is necessary to file for a Demolition Permit when the scope of building demolition is 50% of the building or more. Demolition less than 50% may be filed under an Alteration Application (Alt-II, Directive-2).

General Contractor's DOB Tracking Number

Q: What are the minimum Insurance Certificate requirements to establish a General Contractor's Tracking Number? What is the format accepted by the Department of Buildings? Where is the information submitted?

A: Insurance Certificates must be submitted for Worker's Compensation and Disability Insurance to obtain a General Contractor Tracking Number. They may be submitted in any DOB Borough Office. Certificates must be originals. DOB must be listed as Certificate Holder. New Building and Construction Fence Work Permits require Street Obstruction Bond and Liability Insurance Certificates in addition to the above.

If the individual is a sole practitioner and claims he/she does not require Worker's Compensation or Disability Insurance because they have no employees, then a WC/DB100 Form (Affidavit for NY Business that does not require Worker's Compensation and/or Disability) must be submitted in lieu of the required insurances. The form must be sealed by the Worker's Compensation Board. If the GC is out-of-state, then a DB101 Form is required.

Wheelchair Accessible Viewing Positions

Q: How do I calculate the Minimum Number of Wheelchair Accessble Viewing Positions required for a Place of Assembly or Temporary Place of Assembly? What is the minimum dimension

A: Refer to Building Code Section §27-531(a)(1)(h): Performance viewing positions shall be provided for persons who use wheelchairs in accordance with the following schedule:
Capacity of Assembly Space Number of Viewing Positions
75 to 100=4 min
101 to 150= 5 min
151 to 200=6 min
201 to 300=7 min
301 to 400=8 min
401 to 500=9 min
501 to 1000=2 percent of total
Over 1000=20 plus 1 for each 100 over 1000

Minimum Dimensions of Viewing Position = 30" wide x 48" deep

These positions shall be located so as not to interfere with egress from any row of seats and shall be reachable by means of ramps and/or elevators. Steps shall not be allowed in line of travel from the main approach entry to the designated locations. Size and placement of wheelchair locations, surfaces, access to performing area and listening systems where required, shall comply with the provisions of reference standard RS-4-6. These positions may be utilized by persons who do not use wheelchairs provided that the positions are delineated on the approved seating plans, the seating is readily removable and the positions are unsold one full working day before the performance.

Regular Review versus Professional Certification

Q: What is the diffrerence between Regular Review and Professional Certification? What is Professional Certification of Objections?

A: Regular Review is when the DOB Plan Examiner reviews the plans, and issues approval or Objections which must be resolved by the Archtect or Engineer prior to approval.
Professional Certification is when the Architect or Engineer assumes the role of DOB Plan Examiner by Certifying that their plans & applications comply with the Building Code and Zoning Resolution. The Architect is liable for the accuracy of this statement.
The DOB audits about 20% of the Professionally Certified applications (randomly), and reviews them after issuance of the Work Permit to verify compliance. If a non-compliance is issued, a Letter of Revocation is issued, and the project may be placed on hold until the Audit is resolved. Lack of resolution may result in the permit being revoked.

Refer to DOB OPPN 7/1995. Some details have changed since the issuance of this initial document. Refer to DOB OPPN 1/04 for the updates.

If the units are condominiums, an application must be filed with the Department of Finance to reflect the condo tax lot merger. One of the two kitchens in the apartment must be removed.

What is a Mechanical Deduction?

Q: What is a Mechanical Deduction?

A: A Mechanical Deduction is a floor area deduction where the area used for Mechanical Equipment is subtracted from the Total Zoning Floor Area of a proposed building. When planning a building, Mechanical Deductions should be taken to ensure that the maximum Zoning Floor Area for a site is achieved. Mechanical Deductions should not exceed 2% of the area of the building. Mechanical Deductions may include Plumbing Shafts, Mechanical Equipment Rooms, and similar areas. Key Plans illustrating the location, dimension, and area of each Mechanical Deduction must be provided and tabulated to satisfy DOB requirements.

What is the difference between an Alteration Type-I Application and an Alteration Type-II Application?

Q: What is the difference between an Alteration Type-I Application and an Alteration Type-II Application?

A: An Alteration Type-I Application is required when there is a change to the Certificate of Occupancy of a building, due to an interior conversion of the building or a space within a building, or due to a building addition. Most commonly, an Alteration Type-I Application will be used to change the Maximum Number of Persons for a space, to change the Occupancy or Use Group of a space, and/or to change the Description of a space.

An Alteration Type-II Application may be used when there is no change to the Certificate of Occupancy due to the proposed alterations, such as with an interior fitout or an apartment alteration. When an Alteration Type-II is filed under Directive-14 (such is the case 99% of the time), the Applicant or other NYS Registered PE/RA may signoff the application with a Directive-14 Final Inspection. An Alteration Type-II, Directive-14 Application must include the statement "No Change to Use, Egress, or Occupancy under this Application" on the Title Sheet.
