What Is a Letter of No Objection in NYC?

An LNO is essentially a thumbs-up from the DOB, confirming that your proposed use of a building or planned construction aligns with zoning regulations and building codes. It doesn’t grant permits, but it’s a critical step in securing them. Think of it as a green light before you hit the gas pedal.

When Do You Need No Objection Letter?

Two main scenarios trigger the need for an LNO:


If your building was constructed before 1938 and lacks a Certificate of Occupancy (CO), an LNO verifies its current legal use. This is often required for refinancing, selling, or making major renovations.

Project Planning:

Before certain construction projects, the DOB might request an LNO to ensure the proposed work complies with zoning and safety regulations. This could involve alterations, additions, or even minor renovations.

What Is a Certificate of Occupancy in NYC?

In NYC, a Certificate of Occupancy (CO) is your official thumbs-up from the Department of Buildings. It confirms a building is safe and legal to occupy for its intended purpose (e.g., residential, commercial). New buildings and those undergoing major changes need a CO, and existing buildings may need updated versions for certain alterations.

How Can You Get a Letter for No Objection?

The process for obtaining an LNO varies depending on your specific situation. Here’s a general roadmap:

  • Gather Necessary Documents: This may include property deeds, surveys, architectural plans, and tax assessments.
  • Determine the Type of LNO Needed: Identify whether you need one for existing use or proposed work.
  • Contact the DOB: Visit the borough office where your property is located or use the DOB NOW portal online.
  • Submit your Application: Follow the specific instructions and requirements outlined by the DOB.
  • Pay Any Applicable Fees: Be prepared for processing and inspection fees.
  • Wait for Review: The DOB will review your application and supporting documents.
  • Receive your LNO (or denial): If approved, you’ll receive the official document; if denied, you’ll be notified of the reason and any necessary steps to address it.


Is a Letter of No Objection the Same as a Letter of Verification?

No, they’re not the same. An LNO confirms “permissible use” (existing or planned), while a Letter of Verification confirms the existence of a “valid Certificate of Occupancy”.

How Long Does a Letter of No Objection Take?

Obtaining an LNO in NYC can take “at least one month”, but expect several months if revisions or resubmissions are required.
