Energy Mandates Guide

Condo building with solar panels and energy meters

Over 40 U.S. cities have enacted building performance standards that require large buildings — including most condo complexes — to reduce energy use and emissions on fixed timelines. Non-compliance means escalating fines. Compliance means capital expenditures funded by unit owners. This hub covers the mandates hitting condo owners the hardest.

Denver

Energize Denver is one of the earliest and most aggressive municipal energy mandates, with phased deadlines through 2030.

New York City

Local Law 97 sets carbon emission caps for buildings over 25,000 square feet, with fines that can reach seven figures annually per building by 2030.

Boston

BERDO 2.0 targets net-zero emissions by 2050 with five-year interim checkpoints starting in 2025. Its 20,000 sq ft threshold captures a large share of Boston's condo stock.

Washington, DC

DC's BEPS program applies to buildings as small as 10,000 square feet — a threshold that captures mid-rise condos most other cities exempt.
