Chicago Building Codes Concerning Garage Roofs
Are you planning to build or renovate a garage in Chicago? You must follow the city’s building codes to stay compliant and avoid costly mistakes. Here’s what you need to know about roof design and slope:
If your garage is a detached frame structure up to 600 square feet, you can obtain Express Permit for roof replacement. However, it is applicable for only certain roof types. And these are gable or hip roofs with a slope of 2:12 or steeper.
If you want a flat or low-sloped roof? You can build one, but it requires a plan-based building permit instead of an express permit. It means more paperwork and a longer approval process. However, it is worth the effort. Why? The Chicago Zoning Code allows a maximum height of 15 feet for accessory buildings, including garages. So, a flat roof provides more space.
