Performing construction without a required permit in New York City can result in significant civil penalties from the Department of Buildings (DOB).
The civil penalty increased for work without permit violations following changes introduced through Local Law 156 of 2017. NYC DOB announced the increased penalties in 2018, and the rules continue to establish different calculations for one- and two-family dwellings and other buildings.
For property owners, the distinction matters. The amount assessed can be substantially higher than the original permit fee.
Additional penalties may also apply when unpermitted construction involves repeat violations or work performed in violation of an active Stop Work Order.
This guide explains the published DOB penalty structure, how calculations work, and the process for requesting a civil penalty review.
SLK Buildings can help you review DOB records, understand applicable penalty requirements, and coordinate the steps toward compliance.
From Queens Brooklyn Fully Attached Houses to Bronx Detached Frame House—We’ve Seen It All.
NYC strengthened its civil penalty framework to discourage construction without required permits.
Local Law 156 of 2017 increased the multiplier and minimum penalty amounts for work-without-permit violations.
DOB announced that the increased penalties would take effect on June 18, 2018.
The increase changed the standard penalty calculations for both smaller residential properties and other buildings.
Local Law 158 of 2017 also established additional consequences for certain repeat work-without-permit violations.
These changes are not new 2026 increases. They are part of the existing NYC enforcement framework.

NYC’s published rule, 1 RCNY §102-04, explains how DOB calculates work-without-permit civil penalties.
The applicable property category is based on the occupancy status shown in the Certificate of Occupancy or other Department records.
One- and Two-Family Dwellings
For work performed without a permit on a one- or two-family dwelling, the standard civil penalty is:
Six times the applicable permit fee, with a minimum of $600 and a maximum of $10,000.
The rule also includes work performed inside an individual residential condominium or cooperative unit in this category.
For example, if the applicable permit fee is $200, six times that amount is $1,200.
The resulting standard civil penalty would therefore be $1,200, assuming no additional provisions change the assessment.
Other Buildings and Common Areas
For buildings other than one- or two-family dwellings, the standard penalty is:
Twenty-one times the applicable permit fee, with a minimum of $6,000 and a maximum of $15,000.
This category includes work performed in common areas of condominium or cooperative buildings.
For example, if the applicable permit fee is $400, the calculation would be:
$400 × 21 = $8,400.
The standard civil penalty would be $8,400 before considering any applicable additional penalties.
Examples of Penalty Calculations
The following simplified examples illustrate the standard formula.
Property type | Permit fee | Calculated civil penalty |
One-family dwelling | $75 | $600 minimum |
Two-family dwelling | $500 | $3,000 |
Other building | $200 | $6,000 minimum |
Other building | $1,000 | $15,000 maximum |
These examples are illustrations, not official assessments for a particular property.
DOB determines the actual penalty based on the applicable permit fee, property classification, violation records, and governing rules.
Repeat violations can create substantially greater exposure.
Under Local Law 158 of 2017 and the corresponding provisions of 1 RCNY §102-04, certain subsequent work-without-permit violations within the applicable one-year period can result in a doubled civil penalty.
DOB announced implementation of this repeat-violation provision effective May 30, 2019.
Property owners should not assume that the standard $10,000 or $15,000 cap necessarily represents their total exposure when repeat-violation provisions apply.
The precise assessment depends on the property’s violation history and the applicable statutory requirements.
A review of prior DOB violations is therefore important before estimating the amount owed.

NYC’s civil penalty rules address several special situations.
Work Performed After a Permit Expired
Under 1 RCNY §102-04, work performed after permit expiration is subject to a specified civil penalty:
The rule also addresses work performed after hours without the required variance permit.
Removal of Unpermitted Work
Removing the illegal construction does not necessarily eliminate the civil penalty.
The published rule specifies penalties of $600 or $6,000, depending on the property category, even when the unpermitted work has been removed.
Legalization Before a Violation Is Issued
DOB also distinguishes between work being legalized before a work-without-permit notice of violation is issued and work being addressed after a violation has already been issued.
These situations can involve different filing procedures and fee calculations.
Owners should identify the correct application type before submitting a legalization filing.
Several types of financial obligations may arise from the same construction project.
DOB work-without-permit civil penalties relate to construction performed without required authorization. These are generally addressed through the permit filing and civil penalty review process.
OATH penalties may arise from a separate summons issued for violations of applicable laws or rules.
Stop Work Order penalties may apply when prohibited construction continues despite an active SWO.
NYC DOB currently lists additional civil penalties for violating an SWO:
These Stop Work Order penalties should not be confused with the six-times or twenty-one-times permit fee calculations for the original unpermitted construction.
They are separate enforcement consequences.
The L2 Civil Penalty Review Process
NYC DOB provides the L2 Civil Penalty Review process for applicable work-without-permit and Stop Work Order penalties.
For qualifying DOB NOW: Build applications, an L2 request is created from the filing’s dashboard.
The request identifies the relevant violation and calculates the applicable civil penalty.
Owners or applicants may review the assessment and submit supporting information when requesting an eligible adjustment.
Reductions, Waivers, and Supporting Evidence
DOB permits certain L2 requests for overrides, reductions, or waivers.
Eligibility depends on the specific circumstances and the relevant L2 reason code.
For example, DOB’s process includes requests involving the percentage of work completed without a permit.
Supporting evidence may be required to establish the basis for a reduction or waiver.
Submitting an L2 request does not guarantee approval.
The Department evaluates the application and supporting materials before determining the outcome.
Under 1 RCNY §102-04, applicable work-without-permit civil penalties generally must be resolved before DOB issues the related permit.
The rule also identifies circumstances in which payment is required before accepting a Certificate of Correction or rescinding a Stop Work Order.
DOB NOW: Build explains that an applicable civil penalty must be paid, or an L2 waiver approved, before permit issuance.
This makes the penalty review an important part of the project’s filing schedule.
Property owners should not assume that payment alone legalizes the construction.
Required permits, corrective work, inspections, and other violation resolution steps may still be necessary.
Work-without-permit penalties can involve complicated filing histories, property classifications, and multiple enforcement records.
