Massachusetts just rewrote the rulebook — and most builders haven't caught up.
The 2026 updates to 780 CMR (10th Edition) are the biggest revision in a decade:
• New 3-tier energy code — base, stretch, and net-zero municipal opt-in
• 300+ towns now on stretch code — the rules change at the town line
• New ADU fire separation and egress standards
• EV-ready electrical now mandatory in new 3+ unit buildings
Here's what that means on the ground: the town you pulled a permit in last year may have different energy requirements than the town you're working in today. Miss the tier, fail the inspection, lose weeks.
This is exactly why we exist. Licensed supervision, permit support, and code review under a real MA Construction Supervisor License (CS-118216) — so the paperwork never stops the work.
$500 flat under $25K. 2.5% over.
