The Affordable Dwelling Unit (ADU) and Inclusionary Zoning (IZ) programs of the District of Columbia allows income eligible households to purchase or rent housing at below market prices. The DC government provides incentives to developers to set aside certain units for low- to moderate-income households for purchase or rent through the ADU and IZ programs in order to preserve affordable housing in the city.

Affordable Dwelling Units (ADUs)

For the opportunity to purchase or rent an Affordable Dwelling Unit (ADU), income eligible households should apply directly to the developer or property manager and meet the requirements of that specific property. The District of Columbia does not require that you attend training for the ADU program. HCS assists ADU applicants by completing an income certification, however, applicants should first contact the developer or property management for other property specific requirements.

Inclusionary Zoning (IZ)

Individuals who wish to participate in the Inclusionary Zoning (IZ) Program lottery should register through the DC Department of Housing and Community Development’s (DHCD) Inclusionary Zoning web page at DHCD.DC.ORG. In order to register for the lottery you will first need to determine if you are applying for IZ rental or IZ homeownership and participate in the required training.

* IZ RENTAL UNITS:  In order to be registered for IZ RENTAL properties you must provide proof that you participated in an Inclusionary Zoning Orientation (IZO). 

* IZ PURCHASE UNITS:  If you wish to register to PURCHASE an IZ property, DHCD requires that you provide verification that you have attended an Inclusionary Zoning Orientation (IZO) AND that you graduated from an 8-hour Home Buyer Education Course by a DHCD approved community based organization (CBO).

To participate in an IZO conducted by HCS: please Click Here  to sign up on this website or call us at 202-667-7606 to reserve a seat in an open IZO. Seats are limited and walk-ins are accepted only when seats become available.

To participate in the 8-hour Home Buyer Education Course conducted by HCS:  you must have completed one of the two requirements below BEFORE you can reserve a seat with us for the 8-hour Home Buyer Education Course:

  1. You either have applied for DHCD’s Home Purchase Assistance Program (HPAP) and have received your HPAP Notification of Eligibility (NOE). NOTE:  If you have not yet applied for HPAP but intend to use HPAP funds to purchase a home, you should start this process BEFORE moving forward on IZ.


  1. You have a pre-qualification letter from a lender that is less than 60 days old and that provides you with a loan qualification that meets the minimum purchase price of an IZ unit based on your household size and income (Click Here for most recent IZ purchase price schedule).

In order to move forward in applying for HPAP or preparing for a pre-qualification letter from a private lender, we suggest that you start by attending an HCS Pre-Purchase Orientation (PPO). At the PPO we will explain how to determine if you are ready to buy, how to begin the purchase process and how to apply for HPAP. You may register to attend a PPO on this website or by calling the HCS Training Department at 202-667-7606. 

If you have questions or if you want to reserve a seat for the IZO, PPO or the 8-hour Home Buyer Education Course, please call the HCS Training Department at 202-667-7606.

[Please Note:  the process for registering for the IZO and 8-hour Home Buyer Education Course may differ at each DHCD approved Community Based Organization (CBO). The process described here is for those people working with Housing Counseling Services, which is a DHCD approved CBO. You may reach out to the other DHCD approved CBOs to learn their process for scheduling the required training classes.]


Registrant, Walk-In and Late Arrival Policy

 PRE-REGISTRATIONS: Please arrive on time as your reserved seat WILL NOT be held after the start time for the event even if you have pre-registered and have a ticket. Please be aware that your registration ticket to attend the IZO expires at the start time for the event and any open seats will be immediately distributed to walk-ins at the start time of the event.

WALK-INs / STAND-BYs: Individuals who have not pre-registered and who do not have a ticket will only be admitted IF seats are available AFTER the start time for the event. While we cannot guarantee a seat, we will try our best to accommodate those who arrive BEFORE the start time. Please sign the Stand-By Sheet, which is available at the intake window, to let us know you are waiting. Names will be called from the Stand-By Sheet in the order of arrival. Once all seats are occupied, those still waiting will be notified that the doors are closed and these individuals will need to register for another date.

LATE ARRIVALS: Because the Inclusionary Zoning regulations REQUIRE that participants be certified as having fully participated in the IZO, nobody will be admitted more than 15 minutes after the start time of the event. If you arrive more than 15 minutes late, you will be asked to re-register for another date. There are no exceptions to this rule as regulation requires certification of FULL participation.
