How to Get a Building Permit for Your NYC Renovation
Navigating the NYC Department of Buildings can be overwhelming. This guide demystifies the entire permit process for your home renovation, from understanding when you need one to the final sign-off.
Get Help With Your PermitsIn New York City, the phrase “permits required” can send a shiver down any homeowner’s spine. The process, managed by the NYC Department of Buildings (DOB), is notoriously complex. Yet, for most significant renovations—from a kitchen remodel in Queens to a brownstone gut in Brooklyn—it’s a non-negotiable legal requirement.
Attempting to bypass the system can lead to stop-work orders, hefty fines, and major problems when you try to sell your home. This guide is designed to be your plain-language resource for the entire DOB permit process. We’ll explain what kind of work requires a permit, the different types of applications, the typical timeline and costs, and how an experienced general contractor can be your most valuable asset in navigating the bureaucracy.
Section 1: Do I Even Need a Permit?
This is the first critical question. The DOB’s general rule is that you need a permit for most construction, plumbing, and electrical work. Cosmetic upgrades, often called “decorative work,” typically do not. However, the line can be blurry.

Section 2: Understanding the Lingo: ALT1 vs. ALT2 Permits
If your project requires a permit, it will almost certainly fall into one of two categories: an Alteration Type 1 (ALT1) or an Alteration Type 2 (ALT2). The difference is crucial, as it dramatically affects the cost, timeline, and complexity of your project.

Section 3: The Permit Filing Process Step-by-Step
Getting a permit is not a single action but a sequence of steps that must be followed precisely. The process is managed through the DOB’s online portal, DOB NOW. It requires a Registered Architect (RA) or Professional Engineer (PE) to prepare and submit the plans.

Section 4: Permit Costs & Timeline
The “soft costs” associated with permits can be a significant part of your renovation budget. This includes fees for the architect, engineer (if needed), and the DOB filing fees themselves.

Section 5: The Co-op Board Factor
For co-op owners, the DOB is only half the battle. You must first get approval from your building’s co-op board, which often has rules that are even stricter than the city’s. This process involves submitting an “alteration agreement” package prepared by your architect.
