Completed a renovation without obtaining the required building permit? You may still be able to address the work through the New York City Department of Buildings (DOB), but the process is different from applying for a permit before construction begins.
For property owners wondering how to get a permit when work is done, the first step is determining whether DOB has already issued a work-without-permit violation.
That distinction matters because NYC DOB uses different filing procedures for legalizing completed construction and addressing an existing violation.
Depending on the project, the owner may need professional drawings, permit filings, inspections, corrective construction, and payment of applicable fees or penalties.
This guide explains how the process works and what property owners should know before submitting an application.
SLK Buildings can help you review DOB records and coordinate the steps needed to address completed, unpermitted work.
From Queens Brooklyn Fully Attached Houses to Bronx Detached Frame House—We’ve Seen It All.
In some circumstances, yes.
NYC DOB provides procedures for addressing construction completed without a required permit.
However, an after-the-fact filing does not automatically mean the work will be approved.
The existing construction must be evaluated against applicable building, zoning, and other requirements. DOB may require plans, professional documentation, inspections, or physical corrections.
If the completed work cannot be brought into compliance, removal or restoration may be necessary.
Property owners should avoid assuming that a permit application will simply approve whatever was previously built.

If construction was completed without a permit but DOB has not issued a work-without-permit violation, the filing may qualify as a legalization application.
DOB NOW: Build includes a selection for Legalization of Completed Work where No Notice of Violation for Work Without a Permit was Issued.
DOB explains that a legalization fee is added to the filing when this option applies.
The Department currently identifies a legalization fee of $600 or $6,000, depending on the building category.
This is separate from the ordinary fees and professional expenses that may apply to the project.
The process changes when DOB has already issued a violation for the unpermitted construction.
According to DOB NOW: Build guidance, the applicant should select New Work, not the legalization option, and indicate that the filing addresses an existing violation.
The relevant DOB violation or OATH summons number must be entered.
An applicable L2 Civil Penalty Review is then used to determine the work-without-permit civil penalty.
DOB explains that the applicable civil penalty must be paid or an approved waiver obtained before the related permit is issued.
Choosing the correct filing path at the beginning can help prevent unnecessary administrative delays.
Begin by reviewing the property’s existing permits, approved plans, and violation history.
Determine whether the work was previously authorized under another filing or whether it was performed without the necessary approval.
Check for open DOB violations, OATH summonses, and Stop Work Orders.
The property’s building identification number (BIN) and address can help locate relevant records.
This review establishes whether the project should proceed as legalization of completed work or as a filing to address an issued violation.
Engage an appropriately qualified professional to inspect the completed construction.
Depending on the scope, this may involve a registered architect, professional engineer, Licensed Master Plumber, licensed electrician, or other authorized professional.
The evaluation should determine:
For concealed construction, additional investigation may be needed to confirm compliance.
The responsible applicant must select the filing type that corresponds to the project’s circumstances.
For completed work without an issued work-without-permit violation, DOB provides the legalization option.
For work associated with an issued violation, DOB instructs applicants to identify the violation and follow the applicable New Work and L2 process.
The correct work type also depends on the construction involved, such as general construction, plumbing, electrical, or another regulated trade.
An incorrectly categorized application may need to be withdrawn and refiled.
The applicant prepares the required DOB NOW: Build filing.
Depending on the project, the submission may include:
Not every project requires the same documentation.
More extensive construction may require registered design professional involvement, while certain limited trade work follows different procedures.
DOB reviews the filing according to the applicable requirements.
The financial requirements depend on whether a work-without-permit violation was issued.
For eligible legalization filings without an issued violation, DOB identifies a legalization fee based on the building category.
For filings addressing an issued work-without-permit violation, DOB uses the L2 civil penalty process.
The L2 review can also address qualifying requests for a reduction, override, or waiver.
Separate OATH penalties or other filing fees may apply.
Property owners should confirm the specific assessment rather than assume that all after-the-fact permits carry the same charge.
Approval of a filing does not automatically establish that completed construction complies with all applicable requirements.
If the professional evaluation or DOB review identifies deficiencies, the owner may need to make corrections.
Required inspections and final sign-offs must also be completed.
For an outstanding OATH violation, DOB may require a Certificate of Correction with acceptable supporting evidence.
Keep copies of approved filings, inspection results, and correction documentation for future reference.

NYC DOB explains that a No Work permit is issued when the legalization option is selected on the applicable filing.
This is intended for completed work being legalized rather than authorizing new construction under that filing.
DOB also states that No Work permits cannot be renewed.
If additional construction is necessary, a separate or subsequent filing selecting New Work may be required.
Property owners should not interpret a No Work permit as authorization to perform further construction.
An after-the-fact application is not a substitute for code compliance.
If the construction violates applicable requirements, the owner may need to modify or remove the work.
For example, structural changes may require engineering review, while plumbing and electrical installations may require evaluation by licensed trade professionals.
DOB’s enforcement guidance recommends consulting a registered architect or professional engineer to determine whether an illegal condition can be legalized or must be removed.
The appropriate solution depends on the actual conditions and applicable regulations.
An active Stop Work Order creates additional restrictions.
If DOB issued the order because work was performed without a required permit, both the required permit and formal rescission of the Stop Work Order are necessary before affected construction can resume.
Obtaining a permit does not automatically lift an SWO.
The owner must follow the issuing DOB unit’s correction and rescission procedures.
Continuing prohibited work can result in separate penalties.
Getting construction properly documented after completion may involve permit research, professional evaluations, DOB filings, and inspections.

Can I get a building permit after the renovation is finished?
In some cases, yes. DOB provides procedures for addressing completed work, but approval depends on the project’s compliance and applicable filing requirements.
What is the difference between legalization and a work-without-permit violation filing?
DOB’s legalization option applies to qualifying completed work where no work-without-permit violation was issued. When a violation has already been issued, DOB directs applicants to identify the violation under the appropriate New Work filing and follow the L2 process.
How much does an after-the-fact permit cost in NYC?
Costs depend on the building category, filing type, work scope, professional services, and any applicable penalties. DOB identifies legalization fees of $600 or $6,000 for qualifying filings without an issued violation.
Do I need an architect to legalize completed construction?
Some projects require a registered architect or professional engineer; others may qualify for filings by appropriately licensed trade professionals. The requirements depend on the work.
Can I keep the work if it does not meet code?
Not necessarily. Noncompliant work may need to be corrected, altered, or removed before DOB accepts the resolution.
Does an after-the-fact permit remove a Stop Work Order?
No. DOB must formally rescind an active Stop Work Order before construction covered by that order can resume.
