Since 2019, the Chicago Department of Housing (DOH) has documented and centralized existing design and contracting requirements, as well as other policies and guidelines that govern the construction of multifamily affordable housing development projects in Chicago, into the Architectural and Technical Standards Manual (ATSM). These policies and standards exist to ensure that design and construction provide dignified homes for residents and families, produce durable and long-lasting buildings, set consistent expectations for development teams, and provide for fair and competitive construction contracting.  

The ATSM applies to any multifamily construction or rehabilitation project receiving financial assistance from the Department of Housing, and to select other projects and programs. The 2025 ATSM is the fourth version of the City of Chicago’s manual for architectural and technical standards.

Public Comment

DOH will work closely with residents, advocates and developers to finalize the ATSM this year. The draft will be open for public comment until Monday, July 7, 2025, at 4pm CT. You can submit comments by emailing DOH2025ATSM@cityofchicago.org.

The Chicago Department of Housing invites you to join a virtual public comment meeting regarding the 2025 Architectural Technical Standards Manual (ATSM) on Thursday, June 26, 2025, from 10:00 AM to 11:00 AM. During this meeting, the Department will present the latest updates to the ATSM, followed by an open session for public feedback and discussion. Registration is available here.

We look forward to your valuable input.
