Multifamily Regulation Is Getting Harder — and More Expensive
Falling Behind Has Real Financial Consequences
Across the multifamily industry, regulatory requirements are expanding faster than most teams can track:
New mandates and performance targets often surface too late, leaving little time to respond cost-effectively.
Non-compliance carries increasing financial penalties, retroactive costs, and operational disruption.
Portfolio complexity multiplies risk, as overlapping local, state, and federal rules vary by property and market.
Without a structured system in place, compliance becomes reactive, costly, and unpredictable.
In today’s regulatory environment, not knowing is often the most expensive outcome.

A Message From Our CEO
At GreenT, we’ve had the privilege of engaging with hundreds of leaders across the multifamily industry. One message has been consistent and clear: sustainability is a priority—but navigating today’s regulatory landscape, especially Building Performance Standards (BPS), has become increasingly complex and overwhelming.
We founded GreenT to change that.
Our mission is to simplify sustainability and regulatory compliance for multifamily real estate through intelligent automation. We believe the industry has always had the right intentions—what’s been missing are the tools and systems to translate complexity into clear, confident action.
That’s why GreenT applies AI-driven analysis to real building data, continuously tracking regulatory change, identifying risk early, and guiding teams toward smarter, more cost-effective decisions. By automating what was once manual and fragmented, we help owners and operators manage compliance at portfolio scale—without added headcount or reliance on consultants.
Multifamily leaders deserve solutions purpose-built for their realities. GreenT delivers clarity where there was uncertainty, foresight where there was reactivity, and progress where there was friction—helping teams reduce risk, avoid penalties, and accelerate meaningful improvements in energy efficiency and carbon performance.
Sustainability is no longer optional—it’s becoming core to the future of real estate. At GreenT, we’re committed to being a trusted partner in that future, empowering our customers to lead with confidence, resilience, and impact.
Let’s move the industry forward—together.
