Registration and Certification Fees

WELL certification, a widely adopted rating system, prioritizes enhancing the health and well-being of building occupants through a comprehensive assessment of design, operations, and policies. The process incurs registration and certification fees.

The one-time registration fee, ranging from $2,500 to $5,000, initiates the certification process. It covers the initial project documentation review and provides access to the WELL certification portal, offering guidance and resources.

Upon completing the process, the certification fee is based on the project’s size. For new construction, it typically ranges from $18,000 to $45,000, and for renovations, it varies from $14,000 to $35,000. This fee covers the review of documentation and onsite performance verification by a WELL assessor.

It’s crucial to note that fees may change and are project-dependent. Additional costs might arise if a consultant or WELL AP is engaged to assist with certification.

Despite the costs, many find the benefits outweigh the investment. WELL certification enhances occupant health, productivity, and property values. Acting as a marketing tool, it demonstrates a commitment to sustainability, attracting and retaining tenants.

In summary, prospective WELL certification seekers should be aware of the registration and certification fees. While these may seem substantial, the potential advantages in occupant well-being and marketability make WELL certification a valuable consideration for building owners prioritizing health and sustainability.


How Does It Work


Just after the registration process, the project can also work towards Precertification. Though this step is optional, it can be used to avail certain government incentives such as FAR and for marketing to prospective buyers and tenants. A thorough submission is required, almost at par with the final documentation.


During this phase of the project, the green building specialist plays a vital role in advising the project teams and preparing analysis reports, calculations and other forms of implementation documentation for submission to certification body. The project needs to not only specify as per WELL, but also submit proofs of implementation to the certifying body.


Certification is awarded at the end of construction almost at the time of handover of the project to the end users. The certification body can visit the project and through third party evaluators carry out detailed checking of the documents submitted, and revert with a review requiring a response and submission of additional clarifications.
