When do you not have to install a sprinkler system in a building?

A sprinkler system may not be required in a building if it is classified as a low-rise structure, typically under three stories, and meets specific size and occupancy criteria outlined in local building codes. Additionally, certain types of occupancies, such as agricultural buildings or some residential homes, may be exempt from sprinkler requirements. Local regulations can vary, so it's essential to consult the relevant building codes and fire safety regulations for your area. Always check with local authorities to ensure compliance.
