What Dominion Due Diligence Group (D3G) does

Dominion Due Diligence Group (D3G) is a privately held professional services firm founded in 1994 by Rob Hazelton and headquartered in Midlothian, Virginia. The company provides due diligence, environmental compliance, and consulting services exclusively to the U.S. affordable housing industry, serving Public Housing Authorities (PHAs), lenders, developers, equity partners, and general contractors navigating HUD, RAD, LIHTC, Fannie Mae, and Freddie Mac programs. Service lines span Capital Needs Assessments (CNA), HEROS Environmental Review, Energy & Sustainability certifications (ENERGY STAR, NGBS, LEED, GreenPoint), Environmental Site Assessments (Phase I/II, asbestos, lead-based paint, radon, NEPA compliance), Architectural & Cost Review for HUD 221(d)(4) financing, and housing preservation consulting including RAD conversions and Section 18 repositioning.

D3G operates proprietary data collection tools Versa and Kensa that aggregate property information into a national database supporting assessment consistency and efficiency. The firm piloted HUD's HEROS platform in 2016 and has processed approximately 4,000 Part 50 and Part 58 environmental reviews, accumulating cumulative scale metrics of 20,000+ CNAs, 16,000+ Environmental Assessments, and 200,000+ RAD units assessed across all 50 states plus USVI and Guam. The firm maintains offices in Virginia (headquarters), Colorado, and Indiana, and operates with 101-250 employees supplemented by 1099 field inspectors and environmental specialist partners.

Revenue is generated through fee-for-service, project-based consulting engagements with quote-based pricing tailored to project scope, property count, and service type. Customer acquisition relies on a sales-led, relationship-based go-to-market with business development managers, content marketing (industry blog, case studies, newsletter), and conference participation. The company is founder-owned with no disclosed private equity or venture capital backing, and underwent a leadership transition in which Stephen Evanko was appointed CEO while Rob Hazelton assumed the Chief Innovation Officer role. Recent strategic emphasis has been on professionalizing management, expanding geographic delivery, and adding regulatory advisory capabilities such as Build America, Buy America Act (BABA) compliance review.
