Imagine you're getting ready to sell your property, refinance your mortgage, renovate, or pull a new NYC construction permit. Everything appears to be in order—until someone discovers an open NYC Department of Buildings (DOB) permit or permit application from years ago that nobody knew still existed.

Over the years, I've seen this happen more often than most people realize.

Many property owners do an excellent job maintaining their buildings, managing tenants, budgeting for repairs, and keeping up with day-to-day operations. However, one area that's often overlooked is the property's administrative history with the NYC Department of Buildings (DOB).

An application or permit from a previous renovation may have never been closed out, required inspections may have never been completed, permits may have expired long after the work itself was finished, or a project may have simply remained inactive for years. These issues often go unnoticed until someone is preparing to sell, refinance, obtain a new NYC building permit, update a Certificate of Occupancy, or file a new application through DOB NOW.

During reviews of NYC properties, I've frequently come across issues such as:

• Open DOB permits from work completed years ago
• Expired permit applications that were never renewed or signed off
• Abandoned DOB applications tied to previous owners or prior projects
• Outstanding DOB or ECB violations that continued accumulating penalties
• Boiler compliance issues that were never resolved
• Façade (FISP / Local Law 11) requirements that were overlooked
• Gas piping inspection requirements under Local Law 152 that were missed
• Missing final inspections preventing permits from being signed off and closed
• Multiple permits or applications filed for the same project that remain open or unresolved
• Previous renovations where the physical work was completed, but the DOB records were never fully finalized

Most of these situations don't happen because someone intentionally ignored them. They often result from projects changing hands, contractors moving on, architects and engineers retiring, ownership changes, or administrative items simply falling through the cracks over time. In many cases, everyone is focused on getting the construction completed and enjoying the finished project. It's easy to overlook the administrative side of the process, such as final inspections, permit sign-offs, and making sure DOB records are properly closed out.

One thing I've learned is that reviewing your property's DOB history shouldn't only happen when you're selling or refinancing. It should be part of routine property management, just like maintaining your roof, boiler, elevator, HVAC system, or other building components.

Whether you own a condominium, cooperative apartment, multifamily building, mixed-use property, commercial building, or single-family home, periodically reviewing your NYC DOB permit history, open permits, DOB violations, Certificate of Occupancy, and compliance records can help prevent expensive surprises that delay closings, refinancing, insurance requirements, or future construction projects.
