The application for exemptions can be found through the Clean Buildings Portal. Initial access to the Clean Buildings Portal requires an access code found in the building owner notification letter, or the Clean Buildings staff may grant you shared access upon request. To request a copy of the building owner notification letter or to request shared access, complete the request form. This will provide Commerce staff with the information needed to verify applicants are authorized to view and/or maintain building/parcel information on behalf of the organization.
