Everything You Need to Know About Construction Permits in NYC
Building or renovating in New York City? Most projects — from structural changes to plumbing, electrical, façade work, demolition, or excavation — require permits from the NYC Department of Buildings (DOB). Skipping permits can result in violations, fines, or stop-work orders. This guide explains the types of permits, the step-by-step application process, common pitfalls, and how an experienced expeditor can save you time and money.
What is a Construction Permit?
A construction permit is official authorization from the NYC DOB (or other city agencies) that allows specific work to be performed on a building. Permits ensure projects comply with building codes, zoning, safety standards, and environmental rules. Common permit types include:
- Structural work (load‐bearing changes)
- Plumbing, electrical, mechanical permits
- Façade or exterior alteration permits
- Demolition and excavation permits
- Alteration permits (Type 1, 2, 3 depending on scope)
Why Permits Matter
- Legal compliance: Avoid DOB violations and fines.
- Safety: Ensures work meets code and protects occupants.
- Property value & transactions: Unpermitted work can block sales, refinancing, or insurance claims.
- Liability protection: Permits and inspections reduce legal exposure in case of accidents.
Steps to Get a Construction Permit in NYC
Below is a general roadmap. Specific projects may require additional approvals.
Step | What You Must Do |
---|---|
1. Determine scope & permit type | Identify whether the work is an alteration, structural, plumbing, electrical, façade, demolition, or multiple permit types. |
2. Hire licensed professionals | Architects or registered design professionals (RDPs) usually prepare drawings, structural calculations, and energy compliance documents. |
3. Prepare documents | Detailed drawings, zoning analysis, site plans, and any required reports. |
4. Submit application to DOB | File electronically via DOB NOW or through the required channels and pay fees. |
5. Respond to objections | Address DOB comments and resubmit revised documents as needed. |
6. Permit issuance | Once approved, display the permit on site and begin work. |
7. Inspections | Schedule and pass all required inspections (foundation, framing, MEP, final, etc.). |
8. Final sign-off | Obtain final approvals, Certificates of Completion, or updated Certificate of Occupancy where applicable. |
Common Challenges & Mistakes
- Underestimating permit requirements — some “minor” changes trigger major permits.
- Incomplete drawings or missing calculations cause delays.
- Starting work before permit issuance — leads to violations.
- Failing to respond promptly to DOB objections.
- Missing inspections or failing rough/final inspections.
