About This Market
Chicago's plumbing market is massive - 4,147 licensed establishments statewide means serious competition, especially in Cook County. Winter freeze damage drives emergency calls, while the city's aging infrastructure creates steady work in sewer line replacement and building renovations. Old buildings, harsh winters, and strict city codes keep qualified plumbers busy year-round. Residential service calls dominate, but commercial work pays better if you can handle the bigger jobs.
To work Chicago, you need both state and city licenses - no shortcuts. The city's permit process is straightforward but mandatory for almost everything beyond basic repairs. Build relationships with inspectors and know the local codes inside out. Stock up on parts before winter hits - emergency calls pay premium rates when pipes freeze. Focus on neighborhoods with older housing stock for steady renovation work, but don't ignore the commercial opportunities downtown.
