Buildings with no certificate of occupancy

Older New York City buildings can lawfully have no certificate of occupancy. A letter of no objection is how the City confirms the lawful use instead.

Can you buy a New York City building that has no certificate of occupancy?

Quick Answer

Yes, and it is common. Buildings constructed before the certificate requirement took effect, and never altered in a way that triggered one, can lawfully have none. The Department of Buildings confirms the lawful use in that situation with a letter of no objection, which is what a lender and a buyer should ask for.

What the building may be used for

Who does this land on?

Buyers of pre-war townhouses and small multiple dwellings, their lenders, and sellers who have never had to prove the lawful use before.

What governs it?

  • The Administrative Code, which requires a certificate of occupancy for buildings erected or altered after the requirement took effect
  • The Department of Buildings practice of issuing a letter of no objection to confirm the lawful use of a building that predates the requirement
  • The Zoning Resolution, which still governs what the building may be used for going forward
  • The Multiple Dwelling Law and the Housing Maintenance Code where the building contains three or more dwelling units
  • Lender and title requirements, which frequently ask for documentary proof of the lawful number of units

How does the process run?

  1. Pull the Department of Buildings property profile and every certificate of occupancy in the record, including superseded ones
  2. Where none exists, establish the construction date and confirm no later alteration triggered the requirement
  3. Assemble the historical proof of the lawful use: old job filings, tax photographs, city directories, prior deeds and leases
  4. Request a letter of no objection from the borough office, supported by that record
  5. Where the actual occupancy exceeds what the record supports, treat it as a legalization question rather than a documentation question
  6. Give the lender the letter early, because it is the document that most often holds up a commitment on an older building

Where does it bite in a transaction?

  • A four-unit building is marketed as legal four-family and the record supports two
  • A lender declines the file two weeks before closing for want of a certificate that will never exist
  • A letter of no objection is requested after the contract signs, and the borough office timeline outruns the closing date
  • An appraisal values rent from units the City has never recognized

What exactly is a letter of no objection?

It is a written statement from the Department of Buildings that it has no objection to a stated use of a building that has no certificate of occupancy. It is not a certificate and it does not approve new work. What it does is put the City on record about the lawful use, which is what lenders, title companies and buyers need.

Does a missing certificate make the building illegal?

Not by itself. Age is a defense: a building that predates the requirement and was never altered into it can be lawful with none. What makes a building illegal is occupancy the record does not support, which is a separate question and the one worth answering before the contract.

Who should request the letter, buyer or seller?

The seller is the party with the history and the records, and a well-drafted contract makes delivery of the letter a seller obligation with a date attached. Where the seller will not, the buyer requests it during due diligence, because waiting until the lender asks puts the request on the closing critical path.
