The Inclusionary Zoning Program (IZ) requires that most new and some renovated residential developments include a minimum number of affordable units for rent or sale. Those eligible enter a lottery that assigns these units. C100 in testimony on IZ urges its application in the Downtown; correction of flaws in the formula for the Expanded IZ program that could produce less affordable housing; lowering of eligibility maximums; and expanding the requirements to require a greater percentage of affordable housing in new developments.

Information on the inclusionary Zoning program can be found on the Department of Housing and Community Development website. 2023 IZ Eligibility information can be found here.

C100 Comments on ZC Case No. 23 08

Shelly Repp

In asking for PUD flexibility, Wesley has turned the regular IZ program into a pretzel. In short, the modified IZ program proposed by Wesley is a square peg that doesn’t fit in the round IZ hole. The precedent could have city-wide implications that could undermine the IZ program to the detriment of eligible DC residents. There is a way to include DHCD administered IZ units as part of a student residence program, but this isn’t it. The Applications should be denied.

C100 Comments Zoning Commission IZ Formula

Kirby Vining

C100 submitted comments to the revised Expanded IZ formula, demonstrating through a painstaking analysis that Expanded IZ in some instances could produce fewer affordable units than would be produced under existing IZ provisions.  C100 also questioned whether Expanded IZ would discourage the use of Planned Unit Developments (in favor of matter of right construction), thus limiting the public voice in planning.

C100 Comments Zoning Commission IZ

Kirby Vining

C100 wrote to urge the Zoning Commission not to hold a scheduled vote on final text amendments, citing a grave procedural flaw: the final rule text was based on a formula different from that advertised in the proposed rules issued for comment.  The revised formula was one requested by a building industry trade association in comments filed on the last day for public comment.  The Commission declined to accept C100's filing but nevertheless reissued the rule.

C100 Comments Expanded Inclusionary Zoning

Kirby Vining

C100 testified on proposed amendments to Zoning Regulations to create Expanded IZ, asserting the immense density increases would result in exchange for a relative handful of affordable units.  C100 also noted the thinness of the public record and the outsize influence of the development community in dr.  C100 urged further consideration before draft rules were issued for  public comment.  The Zoning Commission proceeded with the rulemaking.

C100 Testimony Office of Planning Case 20 02 Enhanced IZ

Kirby Vining

C100 testified at the Office of Planning’s July 15, 2020 Roundtable on Case 20-02: Enhanced IZ, arguing both that existing IZ has some problems not dealt with at all by Enhanced IZ, and the proposed Enhanced IZ also would allow map amendments for certain properties, thereby eliminating a contested case where benefits and harms could be entertained.

C100 Comments On Case 04 33I

Caroline Petti

At a time when building affordable housing is of the highest priority for our city, we're hard-pressed to understand why the Office of Planning IZ regulations arbitrarily limit the 10% Inclusionary Unit "Set-Aside".  The 10% "Set-Aside" applies to stick-built construction (not the more expensive concrete and steel construction), but only in zones with a by- right height limit of 50 feet or less.  The height limit of the underlying zone is irrelevant. All stick-built construction projects --regardless of the height limit of the zone they're located in -- should be subject to OP's 10% Inclusionary Unit "Set-Aside".

C100 Comments On DHCD IZ Implementation Proposal

Stephen A. Hansen, Kirby Vining, & Caroline Petti

In general, the Committee of 100 believes DHCD's proposal does a good job of addressing recent Zoning Commission changes to the IZ program as well as incorporating additional streamlining and flexibility into the program' s implementation without compromising its integrity or effectiveness.  We do, however, have concerns about changes DHCD is proposing to the housing cost limitations currently found in Section 2213.5 (f) and (g) of the existing lnclusionary Zoning Implementation regulations. In pa11icular the Committee of 100 is concerned about DHCD's proposed changes to allow IZ households to spend as high as 50% of annual income on housing costs.

C100 Comments On IZ Proposed Rulemaking

Nancy MacWood & Caroline Petti

Comments on a range of issues pertaining to the inclusionary zoning regulations including: the targeted family income, size of units, applicability in DC's Downtown area, arbitrarily limited "Set-Aside" requirements, bonus density, height and lot occupancy requirements, bonus density and small residential projects (i.e., fewer than ten units), city's right-to-purchase inclusionary units, and off-site compliance.

C100 Inclusionary Zoning Flyer for ANCs

C100 Zoning Subcommittee

A group of interested organizations -- called the Coalition for Inclusionary Zoning that includes the Coalition for Smarter Growth, AFL-CIO Metro Washington Council, Fiscal Policy Institute, Jews United for Justice, and some others -- submitted these changes on January 7, 2015. Since that time, the Office of Planning has organized lots of meetings and the Deputy Mayor for Planning and Economic Development asked the ZC to postpone consideration of the proposed changes.

Who was invited to these meetings?

The ZC asked the same question. The answer is developers and building industry reps and the Coalition for Inclusionary Zoning, but no ANCs.
