NYC DOB Permit Expediting for Apartment Renovations

Adding a third-party expeditor adds more opportunity for error. Problems arise when the Architect prepares one part of the project, an outside filing representative enters another, and the Owners suffer unnecessary delays and confusion.

DOB filings contain project data, work types, scope descriptions, construction costs, and supporting documents. When those items are prepared separately from the architectural drawings, inconsistencies create errors, questions or require corrections, and add unnecessary delays to straightforward projects.

NYC DOB Plan examiner comments concern the drawings, code, filing data, or supporting documents. A message passed from reviewer to expeditor to Architect and back again adds another communication layer to an issue the Architect could resolve swiftly.

Apartment projects can change or evolve. If drawings change after approval, the filing may also need to be updated, including a Post Approval Amendment where required.

With third-party expediting an Owner may end up coordinating the Architect, expeditor, Engineers, and building management.

DOB identifies the Registered Design Professional as the Applicant of Record responsible for submitting the application, drawings, and required documents. That is one reason we prefer direct control of our filings.

As a reference, DOB’s fee schedule includes minimum scheduling filing fees in the hundreds of dollars, with additional fees calculated based on construction cost. These figures should not be treated as a quote for a particular project. Plumbing, electrical, amendment, inspection, and other fees may also apply depending on the project scope and development details.

For a full gut renovation of a two-bedroom apartment, DOB processing and permit fees may be expected to start at approximately $1,500+ for the two filings typically required: general construction and plumbing.

Legalization projects are treated differently. DOB processing and permit fees for legalization work may typically start at approximately $6,000+ per filing, even when the physical scope of work is relatively limited.

We compared two apartment renovation projects of similar scope, one of which involved legalization of existing work. The legalization project resulted in DOB processing fees approximately 12 times higher than those for the comparable standard renovation.

There is no single approval time that applies to every apartment renovation.

In 2026, DOB reported an average of approximately five days for the Department’s first review of DOB NOW job filings. An initial review, is not the same as final approval or permit issuance. Speaking from an angle of filing applications in-house, it may take 2 weeks to receive initial feedback/approval from DOB; or sometimes 3 days, it’s rather unpredictable.

If the examiner issues objections, we address them and resubmit the filing for another review cycle. Consultant coordination, incomplete documents, design revisions, co-op or condo approval, LPC review where applicable, and contractor permit requirements can affect the overall schedule.

The most effective way to reduce avoidable delay is to submit coordinated drawings and filing information from the outset, something DOB also emphasizes in its Plan Examination guidance.

For apartments located in an individual landmark or within a New York City historic district, Landmarks Preservation Commission (LPC) review is required in addition to DOB filing.

For many interior apartment renovations, the applicable LPC approval is a Certificate of No Effect (CNE). A CNE confirms that the proposed work requiring a DOB permit will not adversely affect the significant protected features of the landmark property. Interior renovations, plumbing or heating work, and certain other alterations may qualify.

LPC applications are filed through Portico, the Commission’s online permitting system. Certain interior projects may also qualify for an Expedited Certificate of No Effect (XCNE) when the work meets LPC’s eligibility requirements, including limitations on exterior alterations and work affecting designated interior landmarks.

For Apartment Renovation NYC projects, LPC filing is coordinated with the architectural drawings and DOB application so the Owner is not managing separate, disconnected approval processes. Where the work affects protected exterior or significant architectural features, a different LPC permit and review process may be required.
