D.C. Mun. Regs. tit. 11, r. 11-C1002
Developments subject to the Inclusionary Zoning (IZ) provisions of this chapter are eligible for the modifications of development standards and bonus density established in this section.
An Inclusionary Development is eligible for modifications to certain development standards as indicated in the specific development standards of each zone; provided that a Voluntary Inclusionary Development may only utilize these modifications pursuant to Subtitle C § 1001.2(b) if applicable.
Inclusionary Developments, except those located in the BF, HE, NHR, R, RF, SEFC, StE, and WR zones, may construct up to twenty percent (20%) more gross floor area than permitted as a matter of right ("bonus density") as reflect in the zone-specific development standards and subject to all other zoning requirements (as may be modified by the zone) and the limitations established by the Height Act.
An Inclusionary Development that has met its IZ set-aside requirements and used all the bonus density permitted by IZ may be eligible for other bonus density permitted by other chapters of this title, provided the Inclusionary Development's total density does not exceed the FAR- maximum associated with the zone permitting that additional bonus density.
A development exempted by Subtitle C § 1001.6(a) may, nevertheless, utilize bonus density and zoning modifications provided for in this section.
