Code: Gut Renovation (Major interior construction project)
Description: (Gut Renovation) is a major interior construction project where almost all finishes, many systems, and often the layout are removed and rebuilt inside an existing building. It usually takes the space down close to framing and then installs new walls, plumbing, electrical, and other systems.
Practical Meaning: For a NYC homeowner, a gut renovation means you are rebuilding most of the interior and must plan for DOB permits, drawings, budget, and a long construction schedule. It usually needs an Alteration Type 2 filing plus separate electrical and plumbing permits, and strong project management to avoid delays or violations.
Where You May See It: You may see “gut renovation” described in architect or contractor proposals, DOB project descriptions, design-build firm guides, and renovation cost estimates, especially for full apartment or townhouse rebuilds. It can also appear in emails with your design professional when they explain why your project scope needs filings like ALT2 instead of minor repair permits.
Why It Matters: This term matters because a true gut renovation triggers more design work, stricter DOB review, more permits, higher costs, and longer disruption than simple cosmetic upgrades. Understanding that your project is a gut renovation helps you prepare for inspections, code compliance, and possible enforcement if work is done without proper approvals.
