Whole Home Renovation Permits in Brentwood, TN: A Practical Guide for Brentwood and Franklin Homeowners

If you plan to gut the kitchen, move a bathroom, and refresh the rest of the house in one project, the first real question is not tile or cabinets. It is paperwork. Whole home renovation permits in Brentwood, TN follow a clear process, and so do the rules next door in Franklin, but the details differ just enough to trip up homeowners who renovated somewhere else. We are a construction company based in Columbia, and we work on renovations across Williamson County. This guide covers what needs a permit, who can pull it, how inspections work, and where Franklin’s historic district adds a step.

What Counts as a Whole Home Renovation to the Codes Office

To a codes office, “whole home renovation” is not a permit category. What matters is the individual work inside it. Repainting every room and replacing carpet may need nothing. A project that removes the wall between the kitchen and dining room, relocates a shower, adds recessed lighting, and replaces the heating and cooling system touches four separate kinds of review.

Brentwood’s online permitting system reflects that. Interior remodels are filed as a residential renovation, remodel, or repair, and finishing a basement or attic has its own permit type.

The practical takeaway is to write down every piece of the scope before you apply. Reviewers work from what you tell them, and an application that says “kitchen update” when the plan moves a bearing wall will cause trouble at inspection.

Which Parts of a Whole Home Renovation Need a Permit in Brentwood, TN

Plan on permits for:

• Removing or adding walls, especially bearing walls
• Structural changes such as new beams, enlarged openings, or reframed floors
• Relocating plumbing fixtures or adding new ones
• Replacing heating and cooling equipment or reworking ductwork
• New electrical circuits, panels, or lighting layouts
• Finishing a basement or attic

Paint, flooring, and trim are generally treated as cosmetic. When in doubt, call Brentwood Planning and Codes before you start rather than after.

Electrical Permits Go Through the State

The City of Brentwood does not issue electrical permits. Its Codes FAQ states that all electrical and low voltage permits and inspections go through the State of Tennessee Electrical Permit Department. On a whole home renovation, your electrician runs a separate permit and inspection track, and the schedule has to account for it.

The same FAQ limits building and repair work to 7:00 a.m. until dark, and 9:00 a.m. until dark on Sundays. That matters if your crew likes early starts.

What Brentwood Asks of Contractors

Brentwood’s contractor requirements list three documents for every permit application:

• A current Tennessee contractor’s license or Tennessee home improvement license
• A certificate of insurance with workers’ compensation listing the City of Brentwood as certificate holder, or a state exemption
• A Brentwood business tax license or a notarized affidavit

The business tax license applies to companies doing more than $100,000 of work inside the city in a taxable year. Homeowners doing their own work, or hiring and supervising subcontractors on their own residence, file a notarized workers’ compensation affidavit instead. Inspections are by appointment through the city’s inspection line at (615) 661-7077 or online.

Franklin Permits: Similar Rules, Two Big Differences

The City of Franklin’s residential construction page says a building permit is required for all new construction, additions, renovations, decks, pools, and most repair work. Residential plans are submitted electronically as PDFs, and the city says it processes residential applications in 7 working days or less.

Two things set Franklin apart on a whole home renovation.

First, the Franklin building permit does not cover plumbing, mechanical, electrical, or low voltage work. Contractors licensed in those trades pull their own permits. That is normal, but it means one renovation can involve several permits, and each one must close out before you are done.

Second, Franklin has a Historic Preservation Overlay. If your house sits inside it, you must contact the city’s Historic Preservation Planner before any construction permit can be issued.

Renovating a Historic Home in Franklin

Homes in the downtown historic district and nearby neighborhoods like Hincheyville carry extra review. According to the city’s Certificate of Appropriateness page, the Historic Zoning Commission must approve a Certificate of Appropriateness for:

• Additions, including porches, stoops, and decks
• Window alterations or replacement
• Siding or masonry changes beyond minor in-kind repair
• Roofing changes beyond in-kind repair
• New dormers
• Interior alterations that change the exterior appearance

Some minor changes on rear or hidden facades can be approved administratively by staff. The city also encourages applicants to take plans to the Design Review Committee, made up of commission members, for informal feedback before a formal application. On a historic renovation, we recommend it. Adjusting a window plan on paper costs far less than adjusting it after the windows arrive.

Brentwood has its share of older homes as well. Whichever city you live in, ask any contractor about their experience with older framing, plaster walls, and original windows. Those houses reward patience and punish shortcuts.

Who Can Pull the Permit, and the $25,000 Line

Both cities let homeowners pull permits for their own residence. Franklin requires a notarized Homeowner’s Affidavit, and Brentwood requires the notarized workers’ compensation affidavit described above.

Franklin’s construction page spells out the licensing threshold: if the cost of the work exceeds $25,000, a State of Tennessee licensed contractor must pull the permit, with a copy of the license and a certificate of insurance. Nearly every whole home renovation clears that bar. If a contractor asks you to pull the permit in your name on a large job, treat it as a warning sign. It often means they are not licensed for a project that size, and it shifts responsibility for code compliance onto you.

When the Address Says Brentwood or Franklin but the House Is in the County

Mailing addresses in Williamson County do not always follow city limits. Some homes with a Brentwood or Franklin address sit in unincorporated Williamson County, where the county codes department issues permits instead of the city. Check your property tax record or call the city codes office with your address before you apply. Filing with the wrong office is a common and avoidable delay.

The Inspection Sequence on a Typical Renovation

Inspections vary by scope, but a whole home renovation in either city usually runs in this order:

1. Framing inspection once walls are opened and new framing is in
2. Rough plumbing, mechanical, and electrical inspections before walls close
3. Insulation inspection where exterior walls or attics were opened
4. Final inspections for each trade permit and the building permit

The rule on site is simple: no wall gets closed until its rough inspections pass. Drywall that goes up early may have to come back down.

How Permits Affect Your Budget and Schedule

Permit fees are a small slice of a renovation budget, but permit timing drives the schedule. Plan review, historic review in Franklin, and inspection scheduling all sit on the critical path. Build them into the timeline from the start, and order items with long lead times, like windows and cabinets, only after the design is approved.

Frequently Asked Questions

Do I need a permit for a whole home renovation in Brentwood, TN?

Almost always. Structural changes, relocated plumbing, new heating and cooling equipment, basement or attic finishes, and new electrical work all need permits, and a whole home renovation usually includes several of them. Purely cosmetic work like paint and flooring generally does not, but confirm with Brentwood Planning and Codes first.

Can a homeowner pull their own renovation permit in Brentwood or Franklin?

Yes, for their own residence. Brentwood requires a notarized workers’ compensation affidavit from homeowners doing or supervising their own work, and Franklin requires a notarized Homeowner’s Affidavit. In Franklin, work costing more than $25,000 must be permitted by a Tennessee-licensed contractor.

Who issues electrical permits in Brentwood?

The State of Tennessee does. Brentwood does not issue electrical or low voltage permits or perform those inspections. Your electrician applies through the state and arranges the field inspection.

How long does permit review take in Franklin?

The City of Franklin says residential permit applications are processed in 7 working days or less. Clear, complete plans help keep it there. Properties in the Historic Preservation Overlay need historic review first, which adds time.

What is a Certificate of Appropriateness in Franklin?

It is the approval the Historic Zoning Commission issues for exterior work on properties in Franklin’s Historic Preservation Overlay. Additions, window replacement, and most siding, masonry, or roofing changes that go beyond in kind repair need one. Some minor changes can be approved by staff.

Do I need a permit to replace cabinets or flooring?

Straight replacement of finishes is usually treated as cosmetic and does not need a building permit. Once the work moves plumbing, adds circuits, or changes walls, permits apply. A quick call to the codes office settles it.

What happens if I renovate without a permit?

The city may stop the work and require permits after the fact, and an inspector may ask you to open finished walls to see what is behind them. Unpermitted work can also surface during a home sale and complicate the deal. Permitting it up front costs less.
