New York Bathroom Code: 2026 Renovation Rules

Reviewed by HomeMD.ai editorial team · Last updated: October 05, 2026

Understanding the 2026 New York State Building Code

As of 2026, New York State adheres to the 2026 NYS Uniform Code, which became effective on December 31, 2025. This update has significant implications for bathroom renovations, particularly concerning ventilation. The code mandates mechanical exhaust fans that vent directly to the exterior, a crucial step to prevent mold issues. This is a shift from previous codes, which had less stringent requirements for exhaust duct routing and sealing.

Key Code Sections for Bathroom Renovations

For those undertaking bathroom renovations, it's essential to refer to specific sections of the New York State Building Code. Key areas include ventilation (M1505.4), plumbing fixture clearance (P2705.1), and safety glazing around tubs (R308.4.5). The 2026 code places a greater emphasis on energy efficiency and ventilation compared to previous versions, ensuring safer and more sustainable bathroom environments.

Permit Requirements and Fees

Permits are generally required for major bathroom renovations involving plumbing, electrical changes, or structural modifications. Permit fees vary by county and project scope but typically range from $50 to $500. It's advisable to check with your local building department for precise fees. For homeowners looking to tackle non-structural tasks like painting or tile installation, DIY is often permitted, but always verify local allowances as they can differ by city or county.
