As 2025 comes to a close, it’s the perfect time for NYC landlords, co-op boards, and property managers to review plumbing compliance needs heading into 2026. With aging infrastructure, strict city codes, and high penalty fees for non-compliance, staying ahead of inspections and upgrades is more important than ever.
At Boris Mechanical, we help building owners throughout NYC meet their obligations under the law—while protecting tenants, minimizing downtime, and avoiding unnecessary fines.
Here’s your updated 2026 NYC plumbing compliance checklist to keep your building safe, legal, and winter-ready.
✅ 1. Local Law 152 Gas Line Inspections (2026 Districts Due)
Local Law 152 requires all buildings with gas piping systems to undergo inspections by a licensed master plumber every four years, based on your community district.
Due for inspection in 2026:
- Community Districts 10, 11, 12 in all boroughs
What’s required:
- Interior and exterior gas piping inspections
- Submission of GPS1 and GPS2 forms to DOB
- Repairs (if needed) completed within 120–180 days
- Inspection records retained for 10 years
Missed filings can result in a $10,000 fine per building.
✅ 2. Backflow Prevention Device Testing
Backflow devices protect NYC’s water supply from contamination. Annual testing is required by law and must be conducted by a certified tester like Boris Mechanical.
Due annually if you have:
- Fire sprinkler systems
- Commercial boilers
- Irrigation systems
- Multi-unit residential properties
You must submit test results to the DEP. Missed deadlines can result in fees or water service interruption.
✅ 3. Fire Sprinkler System Inspections (NFPA 25)
Most residential and commercial buildings with sprinklers must follow NFPA 25, which requires:
- Monthly churn tests
- Annual inspections
- 5-year hydrostatic testing
Boris Mechanical provides turnkey inspection, testing, and violation removal services throughout NYC.
✅ 4. Boiler Inspection & Annual Tune-Ups
All NYC buildings with boilers must be inspected annually and filed with the DOB. Make sure you’ve:
- Scheduled inspections before year-end
- Addressed any code violations from past years
- Flushed sediment and tuned for fuel efficiency
✅ 5. DOB and HPD Violation Checks
Before 2026 begins, log into DOB NOW and HPD Online to see if your building has any open plumbing-related violations, including:
- Illegal gas work
- Improper venting
- Unpermitted appliance installations
- Incomplete paperwork from past LL152 filings
