Updated 2026 · HERS Rating Company
One of the most common questions we get from Massachusetts builders and homeowners is: “How much does a HERS Rating cost?” Here’s a complete breakdown of 2026 pricing for every project type.
2026 HERS Rating Pricing in Massachusetts
| Property Type | Price Range | What’s Included |
|---|---|---|
| Single-Family Home | $1,850 – $2,500 | Projected + final HERS, blower door, duct testing, 24-hr report |
| Multifamily (per unit) | $650 – $1,200/unit | Per-unit rating, blower door sampling, duct testing, full report |
| ADU / In-Law Suite | $1,600 – $1,850 | Projected + final HERS, all required testing, 24-hr report |
What Affects HERS Rating Cost?
- Number of site visits required — Rough-in inspection, blower door at framing, final blower door and duct test
- Location — Travel time from our central Massachusetts base
- Project complexity — Mixed-use, unusual HVAC systems, or complex building envelope
- Number of units — Multifamily projects qualify for volume discounts
Is a HERS Rating Worth the Cost?
Absolutely. Without a HERS Rating, you cannot obtain a certificate of occupancy in MA Stretch Code communities (which is most of Massachusetts). Beyond compliance, a HERS Rating qualifies your project for Mass Save rebates that can reach $4,000+ per home — more than covering the cost of the rating itself.
