The Metro Nashville department that handles building permits, inspections and code questions.
The Metro Codes department in Nashville handles building permits, inspections and code enforcement for Davidson County. Waterproofing work that involves digging, new drainage, structural repair or electrical for a pump may need a permit or an inspection, and requirements can differ for additions, new construction and commercial buildings. Surrounding cities and counties have their own offices, so the right contact depends on where the property sits.
We are a private company and are not part of Metro Codes. We help you find out what applies, prepare drawings and information and coordinate inspections when your project needs them. Officials make the decisions about permits and approvals, and we encourage you to confirm requirements with the office before work begins.
