Pricing

What certification
actually costs.

Reading and building to the standard costs nothing, always. What you pay for is the proof: an independent inspector tests the house and the GreenHome Institute reviews and records the result. Here's exactly what that costs.

Members pay less, because members keep the standard free.

GreenHome Institute members

The lower rate in every row below. Membership funds the 501(c)(3) nonprofit that publishes and maintains the standard for everyone. On all but the smallest projects, the discount more than covers the cost of joining.

How membership works

Non-members

The standard rate, with no membership required to certify a project. You can certify first and join later; the option is always there.

Fee schedule

What certification costs.

Fees are per project. Multifamily is built up building by building; optional add-ons sit on top. Every price shows the member rate first, then the non-member rate.

Certification fee Members Non-members
Single family $425 $500
Multifamily — one building $1,700 $2,000
Multifamily — each additional building $850 $1,000
Multifamily — each square foot over 50,000 per building $0.025/sq ft $0.025/sq ft
Optional add-ons Members Non-members
Pre-construction plan review Optional $500 $1,000
Badges Each $85 $100
Recertification or advance to a higher level Half the applicable rate above

The $0.025-per-square-foot multifamily rate applies only to floor area above 50,000 square feet in a given building. Fees are set by the GreenHome Institute and may be updated; your inquiry returns a firm, project-specific quote before any commitment.

    How the numbers add up.

    A single-family renovation

    One home, one certification. A GreenHome Institute member pays $425; a non-member pays $500. Add an optional pre-construction plan review to catch issues on paper, and a member's total is $925.

    A two-building development

    First building plus one additional, at member rates: $1,700 + $850 = $2,550. If a building exceeds 50,000 sq ft, add $0.025 for each square foot over. A 60,000 sq ft building adds $250.

    Why are there two prices?

    The lower rate is for GreenHome Institute members. Membership supports the nonprofit that keeps the standard free, and it pays for itself quickly on all but the smallest projects. The higher rate applies to everyone else.

    How is a multifamily fee calculated?

    Start with the first building, add each additional building, then add the per-square-foot rate for any floor area above 50,000 square feet in a given building. The plan review and badge fees, if you want them, are on top.

    What about recertification or moving up a level?

    Recertifying an existing GreenStar home, or advancing it to a higher level, is billed at half the applicable rate above, since you're verifying the delta rather than starting over.

    Is the standard itself paid?

    No. The standard is free to read, use, and build to, forever. These fees are only for third-party certification: an independent inspector tests the house and the Institute reviews and records the result.
