Strike Sections 3202.1 through 3202.4 of the International Building Code in their entirety and insert new Sections 3202.1 through 3202.14 in the Building Code in their place to read as follows:

3202.1

Character of projections.Projections are a privilege, and cannot be claimed as a right. The provisions of Chapter 32 establish limitations on the projections that the code official is authorized to approve. The code official is authorized to further restrict or refuse proposed projections if the code official considers such action best for the public interest.

3202.2

Removal of projections. Approval of projections shall be issued with the understanding and agreement by the applicant that any and all such projections shall be promptly removed upon notice from the code official.

3202.3

[RESERVED]

3202.4

Modification of projection requirements. Where an owner proposes a projection, associated with a project requiring a permit pursuant to Section 105, and the projection is not authorized by the provisions of Chapter 32, the owner shall (a) obtain a modification from the code official as authorized by Section 3202.4.1 where the modification is deemed in the general public interest, or, (b) in the case of foregone construction, as set forth in Section 3202.4.2 obtain approval from the Public Space Committee.

3202.4.1

Modifications in the general public interest. The code official is authorized to grant modifications in the general public interest for embellishments or to enhance views along a street, subject to all the conditions set forth below:

1. The applicant shall submit a written modification request to the code official on an approved form that complies with Section 104.10 as applicable;

2. The modification request shall be referred by the code official to the Department of Transportation (DDOT) and the Office of Planning (OP) for their review and recommendation;

3. No modification request shall be approved without a written report from the Directors of DDOT and OP, or their designees, that covers the review criteria set forth in Section 3202.4.1.1, provided that the code official is authorized to proceed without such a report if DDOT or OP fail to comply with the time period for review provided in Section 3202.4.1.1; and

4. The code official determines (a) the primary object of the modification is not changing of interior arrangements; (b) the modification will not interfere with adjacent buildings and (c) the modification will not create an unsafe condition for occupants of the premises or any portion thereof or for occupants of adjacent premises.

3202.4.1.1

DDOT and OP review and recommendation. DDOT and OP shall have ten business days from the referral date to submit a written recommendation to the code official, provided that the code official may allow for an extension of this period for good cause when requested by DDOT or OP. If DDOT or OP fail to provide the written recommendation required by this section within the specified ten business day period or any extension thereto, DDOT or OP, as applicable, shall be deemed to have no objection to the modification request.

3202.4.1.1.1

Relevant criteria. In reviewing the modification request, DDOT and OP shall consider the following criteria:

1. Whether the proposed modification is inconsistent with the District of Columbia's policies for use of public space and will negatively impact current or future use of the transportation network and infrastructure systems;

2. Whether the proposed modification is not an embellishment;

3. Whether the proposed modification detracts from the public parking and experience of public space; and

4. Whether the primary effect of the modification is the private occupation of public space.

3202.4.1.2

Action on modification request. The code official shall review and approve or deny a projection modification request after considering timely-submitted reports provided by the Department of Transportation and the Office of Planning pursuant to Section 3202.4.1.1.

3202.4.2

Foregone Construction. Foregone construction is deemed to occur when, in conformity with a plan previously approved by the National Capital Planning Commission for improvement of any street or thoroughfare, the owner will permanently forego construction on, or the use of a portion of the owner's lot. In such cases, the code official is authorized to grant a projection modification to authorize projections which shall equitably compensate such owner, if:

(a) the code official determines the public interest will thereby be better served; and

(b) the projection modification complies with the limitations and conditions set forth in Sections 3202.4.2.1 through 3202.4.2.5.

2. The proposed projection shall not extend to within 10 feet (3048 mm) of the lot line extended, on the side of any adjoining structure that does not project or that only contains projections, facing the same public right-of-way, that project into public space less than the proposed projection.

Exception. A portion of the proposed projection shall be allowed to encroach into this 10-foot (3048 mm) restriction zone if the angle formed by the lot line and the face of that portion of the projection does not exceed 45 degrees.

A clearance of not less than 20 feet (6096 mm) above the sidewalk or parking grade shall be maintained under any portion of such projections or supports thereof. Balconies or other projections which in the judgment of the code official will embellish the area, when approved, shall be allowed to be constructed with lower clearances above grade; provided, such clearances shall be at least 8 feet (2438 mm) above walk ways and at least 15 feet (4572 mm) above driveways.

3202.4.2.3
