Mark J. Mazz, Aia, LLC

Mark J. Mazz, AIA, LLC, a sole proprietorship doing business as Mark J Mazz, AIA, provides expert witness testimony and litigative consulting services in federal accessibility compliance and disability rights law enforcement to the Department of Justice and the Department of Housing and Urban Development as a 100% prime contractor, competing in full-and-open procurements without set-aside designation.

Mark J. Mazz, AIA is a small architectural consulting firm based in Hyattsville, Maryland, led by a registered architect with specialized expertise in the Americans with Disabilities Act, the Rehabilitation Act, and the Fair Housing Act. The firm's service portfolio centers on architectural plan reviews, on-site facility assessments, expert witness testimony preparation, and technical reporting in support of federal civil rights litigation and enforcement actions. Work is delivered via time-and-materials and firm-fixed-price purchase orders, with recent engagements ranging from $2,021 to $239,760 in ceiling value.

Customer concentration is pronounced. The Department of Justice Civil Rights Division accounts for 20 of 36 awards ($528 thousand combined potential value), anchoring the vendor's footprint with litigative consultant work on accessibility compliance cases. The Department of Justice Civil Division and the Department of Justice U.S. Attorney's Offices combined place 8 awards ($573 thousand), and the Department of Housing and Urban Development's Assistant Secretary for Fair Housing and Equal Opportunity accounts for 4 awards ($342 thousand). These five entities represent 94% of the vendor's award volume. The top-customers-by-potential-value ranking mirrors the award-count ranking — DOJ Civil Rights Division dominates both metrics — indicating consistent engagement depth rather than a handful of large outlier contracts.

Recent activity accelerated in 2024, with six awards placed after dormancy in 2021–2023, but the vendor does not sit on government-wide IDIQs, GWACs, or standing BPAs. Work is sourced exclusively through individual purchase orders issued directly by customer agencies. Four awards valued at $290 thousand combined face ultimate completion within the next twenty-four months, exposing the vendor to recompete risk across its primary customer set. The vendor holds no subcontract relationships and operates solely as a prime.

Representative recent work includes a $239,760 firm-fixed-price purchase order from HUD's Office of Fair Housing and Equal Opportunity (September 2024) for case enforcement support services and Voluntary Compliance Agreement documentation under Option Year 1; a $29,713.58 time-and-materials purchase order from the U.S. Attorney's Offices (October 2024) for accessibility consulting on ADA and Fair Housing Act compliance; and a $12,600 time-and-materials purchase order from the DOJ Civil Rights Division (April 2026) for litigative consulting services.

Mark has specialized in designing and consulting for persons with disabilities for 30 years having worked for architecture firms, DOJ, HUD, and 8 years his own firm. We focus on ADA, FHA, Section 504, ABA, and local accessibility codes.
