302.5 Verification

STATE AMENDMENT
Evidence that a project meets or exceeds the LEED standard required by Sections 302.2.2 through 302.2.7 or Sections 302.3.2 through 302.3.4, or the Enterprise Green Communities Criteria (or approved substantially equivalent standard) required by Section 302.2.4, shall be submitted to the code official within 24 calendar months after the project’s receipt of the first certificate of occupancy issued for occupiable space in a story above grade plane.

  1. A certification by the USGBC that the project meets or exceeds the applicable LEED standard required by Sections 302.2.2 through 302.2.7 or Sections 302.3.2 through 302.3.4, or, if applicable, a certification by Enterprise Green Communities (or entity that certifies an approved substantially equivalent standard) that the project meets or exceeds the applicable standard required by Section 302.2.4; or

302.6 Financial security

STATE AMENDMENT
Before issuance of the first certificate of occupancy for occupiable space in a story above grade plane of a privately-owned project subject to the provisions of Sections 302.3.2 through 302.3.4, the applicant shall provide to the code official evidence of financial security to cover the amount of fine that would be imposed under the Green Building Act for non-compliance with the provisions of Sections 302.3.2 through 302.3.4.
The amount of the potential fine on a project, and thus the amount of financial security, shall be as follows:
  1. $7.50 per square foot of gross floor area of construction if the project is less than 100,000 square feet (9290 m2) of gross floor area of the project.
  2. $10.00 per square foot of gross floor area of construction if the project is equal to or greater than 100,000 square feet (9290 m2) of gross floor area of the project.
     The amount of a fine for non-compliance under this subsection, and thus the amount of security, shall not exceed $3,000,000. When applying the provisions of Section 302.6 to interior construction of a mixed use space in a residential project covered by Section 302.3.3, the gross floor area of the project shall be deemed to mean the contiguous gross floor area, exclusive of common space, of the non-residential occupancies. The amount of this fine shall be subject to modification based upon the form of security for performance as provided for in Sections 302.6.2.1 through 302.6.2.3.
The financial security requirement shall be met through one of the following four methods:

302.6.2.1 Cash

STATE AMENDMENT
If this option is elected, cash shall be deposited in an escrow account in a financial institution in the District in the names of the applicant and the District. A copy of a binding escrow agreement of the financial institution shall be submitted to the code official in a form satisfactory to the Office of the Attorney General, which provides that the funds can be released upon direction of the District where remitted pursuant to Section 302.7. If cash is used as the financial security, the amount of the financial security posted shall be discounted by 20 percent.
If this option is elected, an irrevocable letter of credit benefitting the District shall be submitted to the code official in a form satisfactory to the Office of the Attorney General from a financial institution authorized to do business in the District. The irrevocable letter of credit, issued by the financial institution, shall comply with applicable regulatory requirements. If an irrevocable letter of credit is used as the financial security, the amount of the financial security posted shall be discounted by 20 percent.

302.6.2.3 Bond

STATE AMENDMENT
If this option is elected, a bond benefitting the District, which complies with applicable regulatory requirements, shall be submitted to the code official in a form satisfactory to the Office of the Attorney General. If a bond is used as the financial security, the amount of the financial security posted shall be discounted by 20 percent.

302.6.2.4 Binding pledge

STATE AMENDMENT
If this option is elected, a binding pledge shall be submitted to the code official in a form approved by the Office of the Attorney General. The binding pledge shall be recorded as a covenant in the land records of the District against legal title to the land in which the project is located and shall bind the owner and any successors in title to pay any fines levied under Section 302.7.1.

302.7 Enforcement

STATE AMENDMENT
Where a project fails to provide pursuant to Section 302.5 satisfactory verification of the project’s compliance with the requirements of Sections 302.3.2 through 302.3.4 within the prescribed time frame and any extensions thereof granted by the code official pursuant to Section 302.5.2, the code official is authorized to draw down on the financial security submitted as cash, irrevocable letter of credit or bond, by submission by the District of the original security documentation, provided that where a binding pledge has been provided, to enforce such pledge agreement pursuant to its terms. The amounts thus drawn down from the financial security shall be deposited in the Green Building Fund set up under the Green Building Act.
If a project fails to provide satisfactory verification of compliance, the drawdowns of the financial security in the form of cash, irrevocable letter of credit, or bond shall be as follows:
  1. Failure to provide proof of compliance within 24 calendar months after the project’s receipt of the first certificate of occupancy for occupiable space in a story above grade plane: 100 percent drawdown; or
  2. Miss up to three LEED points in the applicable LEED standard: 50 percent drawdown; or
  3. Miss more than three LEED points in the applicable LEED standard: 100 percent drawdown.
If a project fails to provide satisfactory verification of compliance within 24 calendar months after the project’s receipt of the first certificate of occupancy for occupiable space in a story above grade plane and a binding pledge is used as the form of financial security, one or more fines shall be due and payable per the amounts set out in Section 302.6.1 as may be modified pursuant to Section 302.7.1.
If, within 24 calendar months following the issuance of the first certificate of occupancy for occupiable space in a story above grade plane, the project fulfills the requirements of Section 302.5, the financial security shall be released by the District of Columbia and, as applicable, returned.

302.9 Remediation

STATE AMENDMENT
If within 24 months after receipt of the first certificate of occupancy for occupiable space in a story above grade plane, or within the extension periods granted to the project per Section 302.5.2, the project does not meet the requirements of Section 302.5, the project owner shall, at its own cost, design and renovate the existing building to meet or exceed the current edition of the LEED standard for Existing Buildings: Operations & Maintenance at the Certified Level. The project owner shall submit sufficient data to the code official to verify compliance with this section. The project owner shall provide to the code official certification, by the owner’s registered design professional or an approved agency or an approved source that the project complies with this section.

302.10 Additional fine

STATE AMENDMENT
If within 48 calendar months after receipt of the first certificate of occupancy for occupiable space in a story above grade plane, a project subject to Section 302.3 fails to provide satisfactory verification in accordance with the provisions of Section 302.5 or Section 302.9, the project owner shall pay a monthly fine of $0.02 per square foot of gross floor area of the project to the District of Columbia. The fine shall be a civil penalty, due and payable annually. The fine shall be in addition to any fines issued under Section 302.7 and shall not be subject to the $3,000,000 limit under Section 302.6.1.

302.11 Appeals

STATE AMENDMENT
Determinations made by the code official under Sections 302.2 through 302.10 may be appealed pursuant to Section 112 of the Building Code.

302.12 Exemptions
