Why Do Building Codes Matter?
Building codes are a set of regulations that govern the design, construction, alteration, and maintenance of structures. These are enforced by the City of Knoxville’s Plans Review & Inspections Department to ensure safety, structural integrity, and consistency.
According to the International Residential Code (IRC)—adopted by Knoxville and the State of Tennessee—porch roofs are considered structural additions, and therefore must meet specific criteria in:
- Load-bearing capacity
- Materials and framing
- Weather resistance
- Anchorage and footings
- Drainage and water shedding
Failing to meet these codes could result in denied permits, fines, or even forced demolition.
