In July 2025, the City Council passed Intro 1321-2025, creating New York City’s first Existing Building Code (EBC). While the Construction Codes have long governed new development, the EBC focuses specifically on alterations, repairs, additions, and maintenance for existing buildings.
The law goes into effect on November 7, 2025. Any project filed with the Department of Buildings after that date will be reviewed under the new code. For condo and co-op boards, that means upcoming renovations and maintenance projects could face new requirements.
Why this matters for condos and co-ops
Most board projects aren’t new high-rises — they’re upgrades and repairs to existing systems. The EBC is meant to simplify compliance while also raising safety and sustainability standards. For boards, the biggest impacts will likely be felt in:
- Renovations. Apartment renovations, lobby improvements, or amenity upgrades may need to follow new rules around accessibility, energy efficiency, and fire protection.
- Maintenance work. Routine projects like roof repairs or elevator modernizations could trigger requirements that didn’t apply in the past.
- Change of use. Converting a basement into a gym or storage into office space may now come with clearer — and stricter — obligations.
This shift is part of a broader wave of NYC building regulations, alongside laws like Local Law 11, which governs façade safety, and Local Law 97, which sets emissions caps.
Key updates boards should understand
- Clarity around alterations. The code defines thresholds for when an alteration is considered “substantial,” meaning newer construction standards kick in. That helps boards and architects better scope projects.
- Accessibility requirements. Depending on the work, upgrades may now need to include improved accessibility features such as ramps or doorway clearances.
- Energy and sustainability. The EBC aligns with the city’s climate goals, so major replacements may need to meet higher efficiency standards.
- Fire safety. Upgrades to building systems, from sprinklers to alarms, may require modern fire protection measures.
How boards can prepare
With the November 7 effective date approaching, boards should:
- Work closely with design professionals. Architects and engineers can confirm whether planned projects will trigger EBC compliance.
- Plan your filings carefully. A project filed before the deadline may be reviewed under the old code, while one filed after must meet the new standards.
- Budget for compliance. Accessibility or efficiency requirements could raise costs, so include contingencies in your capital planning.
- Communicate early. Let residents know why timelines or costs might shift. Clear updates, like those outlined in our guide to communicating about common charge increases, help build trust.
The takeaway
The Existing Building Code is a reminder that compliance isn’t just for new towers — it applies directly to the day-to-day projects condo and co-op boards oversee. With the law taking effect on November 7, 2025, boards that coordinate with their professionals now will avoid costly surprises, keep projects moving, and stay aligned with the city’s broader safety and sustainability goals.
