There are two components to the certification process—the Initial House Assessment and the Formal Certification. The initial house assessment is performed to establish a baseline and what minimum improvements will need to be made. Once this is completed, the builder/owner will have the option to continue with the certification process.

1) Initial Assessment: A $775 flat fee per home under 3000 square feet ($475 paid online at time of project registration). Homes exceeding 3000 square feet will be charged an additional $.15 per square foot. For homes for which to scale plans are not provided and additional $200 fee will be charged.  

2) Certification: A flat $650 fee which covers the first 8 hours of work completed by Viridiant and Viridiant staff. After 8 hours of work, the builder/owner will be billed on an hourly basis at $75/hour.
