NYC DOB Earthwork Permit and Requirements
An Earthwork (EA) permit covers applicable excavation, grading and earth movement activities regulated through DOB. An owner may need EA review when excavating for site preparation, lowering grades or working near existing buildings. The depth, surrounding conditions and planned work affect the required protection and professional involvement.
Start with the DOB Permit Types and Certificates of Operation directory for the complete work-type list, or use the Department of Buildings Table of Content for wider NYC DOB subjects. Check the work scope and responsible applicant before treating an application as an issued authorization.
What Is an Earthwork Permit?
An Earthwork (EA) permit covers applicable excavation, grading and earth movement activities regulated through DOB. It is distinct from work that constructs foundations or retains soil beside an excavation.
The contractor and design team should coordinate excavation sequence, neighboring structures, subsurface conditions and any necessary site-safety protections.

When Does This DOB Authorization Apply?
Deciding whether this authorization applies requires a property-specific review of the proposed work, the existing conditions and the current agency records. In particular, compare site survey, proposed excavation footprint and grading elevations, along with soil information and relevant geotechnical recommendations.
Earthwork planning begins with the amount and location of soil movement, anticipated site grades, and the relationship to existing structures. An EA filing is not the same as a Foundation permit or a separate Support of Excavation system. A project may need more than one of these approvals, depending on how excavation, grading, retaining systems, and foundation construction interact. Review the proposed excavation boundaries against property lines, utilities, and adjacent buildings with the responsible professionals before deciding which filings to prepare.
Work Type, Agency and Permit Boundaries
Earthwork (EA), Foundation (FO) and Support of Excavation (SE) are separate DOB work types. DOB states that a Foundation filing does not automatically require an Earthwork filing, and combinations have specific limits.
DOB NOW: Build is the standard current filing platform for this subject. The authorized filer and contractor roles depend on the regulated work, and separate agency permissions may still be necessary.
Steps to Request or Review the DOB Authorization
Use the following sequence to avoid applying against the wrong property record or work scope:
- Confirm the building address, Building Identification Number (BIN), and existing job or equipment record. Check whether the project is new work or an older open job.
- Define the exact work or certificate need with the authorized professional. Compare the project details with the DOB work type and any separate trade or agency approvals.
- The applicant submits the Earthwork work type in DOB NOW: Build and coordinates related work types where the scope allows. Applicable contractor permit and site-safety approvals must be in place before excavation.
- Review the submitted filing and DOB status. Address objections, missing documents, required attestations and pre-permit conditions through the authorized applicant.
- Confirm the issued permit or certificate and the approved work limitations before acting. Save the final record and track inspection or completion duties.
Documents and Information to Prepare
The responsible applicant should assemble project-specific information before starting the filing or records review:
- Site survey, proposed excavation footprint and grading elevations.
- Soil information and relevant geotechnical recommendations.
- Adjoining-property and excavation-protection details.
- Related FO or SE filings, approved drawings and permit status.
DOB Review, Inspections and Closeout
Track inspections and confirm that the approved earthwork scope matches the work performed. Changes in excavation depth or support methods may require revised plans or an additional permit.
An application marked approved, a permit issued and a project signed off are different milestones. Review the applicable status in DOB NOW or BIS, and retain supporting inspection and closeout documentation for the property record.
Prepare the grading drawings, excavation sequence, and the relevant site-condition information as a coordinated record. If the earthwork plan changes after approval, check whether the updated dimensions or methods affect other filings, such as FO, SE, or Protection and Mechanical Methods. Site work should be scheduled around the actual permits issued for each scope, not simply the date the first job was approved. Keep any special inspection and completion documentation associated with the proper work type.
Common Problems to Avoid
Confusing soil removal with foundation construction
Review the distinct EA and FO work-type scopes.
Support of excavation omitted
Assess shoring and adjacent property protection separately.
Unexpected field conditions
Coordinate design-professional review before expanding the permitted excavation.
How SLK Buildings May Assist
SLK Buildings may assist with Earthwork Permit coordination by reviewing available DOB records, organizing project information and identifying which applicant, licensed contractor or agency contact needs to handle the next action.
The authorized design and trade professionals remain responsible for regulated submissions and work, and DOB controls permit decisions, inspections and completion. Owners can begin by gathering the property address, existing filing numbers and a clear description of the proposed work.
Frequently Asked Questions
Does an Earthwork permit automatically cover foundations?
No. Foundation is a separate DOB work type.
Can Earthwork and Foundation be combined?
DOB allows certain combinations, subject to the job and permit-holder conditions.
Is an SE permit included automatically?
No. Support of Excavation has its own filing and review rules.
Seeking Professional Guidance on NYC DOB Permits and Certificates
Property owners and project teams may need to confirm which DOB authorization applies, distinguish historical permits from current work types, and organize existing drawings, job numbers and approved records. When permits, certificates or multiple trades are involved, the responsible professionals and DOB must determine the permitted scope and required approvals.
