Essential guide for NYC property owners and renovators
Renovating in New York City isn’t just about paint colors and tile choices — it’s also about navigating building codes and permits. The NYC Department of Buildings (DOB) issues violations when construction work doesn’t meet city regulations. These violations can delay your renovation, cost thousands in fines, and even block property sales.
This article helps you understand what DOB violations are, how to fix them, and most importantly — how to prevent them.
🏛️ What Is a DOB Violation?
A DOB violation is a formal notice from the NYC Department of Buildings stating that a property or renovation project does not comply with building code, zoning, or safety regulations.
There are three main types of violations:
1. Class A – Non-Hazardous
- Examples: Failure to file a required permit, expired scaffolding signage, minor paperwork issues
- Fines may apply, but usually no immediate risk
2. Class B – Hazardous
- Examples: Unpermitted electrical or plumbing work, lack of safety barriers during construction
- Must be corrected promptly, and inspections are required
3. Class C – Immediately Hazardous
- Examples: Unsafe structure, illegal gas or electrical connections, obstructed fire exits
- Work must stop immediately. Fines are high and enforced strictly.
🛑 Common Causes of Violations During Renovation
- 🔧 Starting work without proper DOB permits
- 🧱 Structural changes without architect approval
- ⚡️ Using unlicensed electricians or plumbers
- 🧾 Failure to post permits visibly at the site
- 🧯 Inadequate fire safety compliance (sprinklers, egress)
- 🚫 Working outside permitted hours (especially in residential areas)
- 🗂️ Failing to file necessary reports or inspection requests
🧠 Many violations are preventable by working with licensed professionals and following DOB rules carefully.
🧭 How to Check for Violations on a Property
Before starting any renovation, check your property’s violation history using:
👉 DOB BIS Property Profile
👉 DOB NOW: Safety
Enter the block and lot number or building address to review:
- Active violations
- Complaints
- Open permits
- Required inspections
🛠️ How to Fix an Active Violation
Step 1: Determine the Type
Visit DOB NOW or request a copy of the violation notice. Review the violation number, description, and class.
Step 2: Correct the Condition
This may involve:
- Hiring a licensed professional to fix the issue
- Re-applying for missing permits
- Removing illegal work (e.g., unauthorized extensions or connections)
Step 3: Submit a Certificate of Correction
Once the issue is fixed, your contractor or architect must file a Certificate of Correction via DOB NOW. Inspections may be scheduled to verify the correction.
Step 4: Pay Fines (if required)
Some violations come with civil penalties or ECB fines (Environmental Control Board). These must be paid to close the violation.
Step 5: Confirm Closure
Use DOB NOW or BIS to verify that the violation status is marked “Resolved” or “Cured.”
🔁 What If I Bought a Property with Existing Violations?
Unfortunately, DOB violations “run with the building,” not the owner. If you buy a property with open violations, you are responsible for resolving them.
💡 Tip: Always run a DOB report before closing a real estate transaction.
