How to Find Detroit Government Contracts for Small Businesses

Detroit is the largest city in Michigan and the center of a major industrial metro. With a large general-services operation, one of the biggest municipal water and sewerage systems in the country, and an active public works program, the City of Detroit is a substantial buyer of construction, professional services, and goods. Here’s how Detroit government contracting works, who can bid, and how to find the right opportunities.

How Detroit procurement works

The City of Detroit manages competitive procurement through its Office of Contracting and Procurement, which publishes solicitations on the City of Detroit (Bonfire) portal. Departments post Invitations for Bid (IFB), Requests for Proposals (RFP), and Requests for Qualifications (RFQ) for construction, professional services, goods, and technology.

You can browse open solicitations on Bonfire without an account. Each listing shows the title, reference number, type, closing date, and the requesting department. To download full bid documents or submit electronically, register as a vendor on the Bonfire portal. Registration is free.

Who can bid on Detroit contracts

Any registered business can bid on City of Detroit contracts. The city runs programs to broaden participation by local and disadvantaged firms:

• Civil Rights, Inclusion & Opportunity (CRIO) — the city department that administers contractor inclusion and equal-opportunity requirements, working to expand participation by Detroit-based and disadvantaged businesses on city contracts.
• Detroit-based business preference — the city encourages contracting with businesses headquartered and operating within Detroit, which can factor into how contracts are awarded.
• Open competition — non-certified businesses can still win prime contracts. Inclusion requirements shape how primes structure subcontracting, not your eligibility to bid directly.

Federal certifications like 8(a), WOSB, or SDVOSB don’t automatically transfer to city programs, but the underlying documentation supports your application.

Common contract categories in Detroit

• Detroit Water & Sewerage Department (DWSD) — one of the largest municipal water and sewer systems in the country, with recurring procurement for treatment, pipelines, pump stations, engineering, and maintenance.
• General Services Department (GSD) — manages city facilities, parks, and fleet, procuring construction, maintenance, equipment, and related services.
• Public Works — street and bridge construction, drainage, traffic systems, and infrastructure across the city.
• Facilities & professional services — janitorial, HVAC, electrical, security, and construction for city buildings, plus consulting, engineering, IT, and staffing.

Tips for winning Detroit contracts

Engage with CRIO requirements early. Understanding the city’s inclusion and Detroit-based business expectations helps you position your bid and find subcontracting opportunities on larger contracts.

Register on Bonfire early. Vendor registration is free but takes a little time — complete it before a solicitation you want closes.

Target DWSD. Water and sewerage work is a steady, high-volume source of construction and engineering solicitations where a specialized firm can build a track record.

Layer city and state monitoring. Detroit city procurement and Michigan state procurement are separate systems — cover both for full visibility in the region.
