Full Breakdown

Under D.C. Code § 6-1451.03, any privately-owned building or project with at least 50,000 square feet of gross floor area must be verified as meeting the current LEED standard for commercial and institutional buildings at the certification level within two years of receiving a certificate of occupancy. Applicants submit a green building checklist to the Department of Consumer and Regulatory Affairs with the building permit application, and beginning January 1, 2012, must post financial security -- cash escrow, a letter of credit, a bond, or a binding pledge -- before the certificate of occupancy issues, per § 6-1451.05. Public schools must reach the gold level if funding allows.

Violations & Fines

Building owners who skip LEED verification or fail to post financial security risk denial of the certificate of occupancy and forfeiture of the required escrow, bond, or letter of credit.
