Residential Building Permits

Chattanooga residential building permits apply to new single-unit construction, ADUs, and work that alters an existing footprint, with contractor licensing and owner-builder requirements.

Permit and scope questions

Chattanooga's residential building permit application is used for new construction single-unit detached or attached homes, ADUs, or work altering the existing footprint.

Zoning and placement

Residential building permit review may involve current zoning code requirements, and land disturbing permits follow the new zoning ordinance with no grace period.

Building and trade review

Contractors need the appropriate Tennessee contractor license, workers' compensation proof or exemption, and in some cases a Chattanooga business license.

Discuss your project early when: Call before applying if the project is an ADU, addition, footprint change, owner-builder permit, licensed contractor project, or involves land disturbance.

Residential Modification Permits

Chattanooga residential modification permits cover repair, replacement, and alteration work that does not alter the footprint, including interior remodels, deck replacement, porch repair, roofing, windows, doors, and siding.

Permit and scope questions

Chattanooga's residential modification permit applies to existing single-family units when the work does not alter the footprint.

Zoning and placement

If the work alters the footprint, it belongs under the residential building permit path rather than the modification path.

Building and trade review

The modification category covers total or partial interior remodels, replacing an existing deck, repairing a porch, re-roofing, windows, exterior doors, and siding replacement.

Discuss your project early when: Call before applying if a deck replacement changes size, a porch repair changes structure, or a repair begins to alter the building footprint.

Retaining Wall Permits

Chattanooga requires a retaining wall or reinforced slopes permit for walls four feet or higher, with site plans and engineering sealed by Tennessee-licensed professionals.

Permit and scope questions

For Chattanooga, ask the permit office to confirm the height or depth limit and the grade or reference point used for measurement and whether retained soil, adjacent slopes or supported loads require engineering before treating this project as exempt or permit-required.

Zoning and placement

Ask Chattanooga's planning or zoning office to check the setbacks, easements and public-space constraints for the parcel for the proposed site and use.

Building and trade review

Applications require a site plan stamped by a Tennessee-licensed professional and retaining wall calculations signed and sealed by a Tennessee-licensed professional engineer.

Discuss your project early when: Contact Chattanooga before ordering materials or starting work to resolve whether retained soil, adjacent slopes or supported loads require engineering; the charger type, new circuit work and allowed equipment locations; and the setbacks, easements and public-space constraints for the parcel. Bring the proposed dimensions, location and scope so the answer is tied to the project.

Demolition and Meter Inspection Permits

Chattanooga demolition permits can require land-disturbing applications, air-pollution approval, sewer capping inspection, and separate meter inspection rules when power has been off for more than a year.

Permit and scope questions

Chattanooga requires a residential demolition permit when any building, structure, or interior is demolished, and interior removal during renovation may require demolition permitting.

Zoning and placement

Demolition that removes footings or foundations or uses heavy equipment requires a land-disturbing application with site plan contours and silt-fencing location.

Building and trade review

Demolition cannot begin until sewer is properly capped at the property line and inspected; meter inspections apply when power has been off over a year.

Discuss your project early when: Call before demolition if foundations will be removed, heavy equipment is used, interior materials are removed, air-pollution approval may apply, or power has been off for more than a year.

Residential Building Permits

Chattanooga residential building permits apply to new construction, ADUs, work that alters the existing footprint, and other residential scopes that need city review.

Permit and scope questions

Chattanooga uses its OpenGov portal for residential building permits, and the city describes this permit path for new construction, single-unit work, ADUs, and footprint changes.

Zoning and placement

Zoning review can affect the permit path, especially when the project changes footprint, uses a new zoning code standard, or involves land disturbance.

Building and trade review

Applicants should prepare contractor, owner, site, and construction information before using the online application because the project may need review before issuance.

Discuss your project early when: Call before applying if the project includes an ADU, addition, footprint change, land disturbance, owner-builder work, or a contractor licensing question.

Residential Modification Permits

Chattanooga residential modification permits cover many repairs, alterations, remodels, and exterior replacements that do not alter the existing footprint.

Permit and scope questions

Chattanooga describes its residential modification permit for existing-structure work that does not alter the footprint, including interior remodels, deck replacement, porch repair, roofing, windows, doors, and siding.

Zoning and placement

Even when a project uses the modification path, homeowners should confirm zoning, historic, land disturbance, and right-of-way issues before starting exterior work.

Building and trade review

Modification projects can still involve building and trade inspections, especially when structural, electrical, plumbing, mechanical, or covered work is included.

Discuss your project early when: Call before applying if the project changes layout, affects structure, replaces a deck or porch, includes trade work, or could shift from repair into addition work.

Prepare a complete application conversation

Bring enough detail for staff to identify the correct application. Ask which plans need dimensions or a professional seal, how files should be named, and whether other departments must approve the proposal first.
