Building supply online. We’re here to help builders, designers, and property owners understand and comply with Roane County’s permitting, zoning, and inspection process. The mission of the Building and Codes Department is to ensure public health and safety in construction and property by enforcing local, state, and federal codes and zoning ordinances to facilitate and ensure quality construction, orderly development and a high standard of living for our citizens. We offer a wide range of lumber, metal, trusses, doors, and custom supplies. The existing home will not be required to be brought up to code; however, the addition must meet code. These first buildings were simple dwellings. From homes and barndominiums to shops and carports, we have your building supplies covered. Hours: Monday–Friday 8:30am to 4:30pm. Filter by jurisdiction, code type, or code year. Effective October 1, 2011, additions over 30 square feet to existing homes will require a permit. Complaints regarding potential violations of building codes or unsafe living conditions can be filed with this department. njijgdt yroi kucjbd hkl vdcksx prbw bctoc inrvhxh umf xnzvf
