Foundation Repair Rules in Tennessee: What Chattanooga, TN Homeowners Should Know
Any foundation work on a home in Chattanooga, TN, the seat of Hamilton County, runs into state license law, Tennessee's consumer rules and a local permit office. This page lays out each one plainly.
The Rules in Brief
- Two license tiers. In Hamilton County and Bradley County, home repair jobs take a state license: Home Improvement from $3,000 to $24,999, contractor's from $25,000. Check any number on verify.tn.gov.
- Everything on paper. A signed contract with the price, work, dates and license number, a deposit within the one-third limit, and signed change orders.
- Local permits. The city or county holding your address issues any permit; ask who pulls it.
- A narrow cancel right. It reaches sales made by a seller who came to your home, not every contract.
This page restates public law and official pages in plain words; it is general information, not legal advice.
Who Can Do Foundation Work in Tennessee
In Hamilton County and Bradley County, the state licenses most of these jobs. There, a state Home Improvement license covers home repair jobs from $3,000 to $24,999, and from $25,000 up a state contractor's license is needed.
Only nine Tennessee counties use the Home Improvement law, Hamilton County and Bradley County among them, per the Board for Licensing Contractors. Its definition reaches repair or remodeling of a residential building of one to four units, and it adds: "A license is required even when no permit is needed." The statute (§ 62-6-501) leaves out contracts of $3,000 or less. The Board's examples don't name foundations, so read this as covering home repair jobs generally.
The Board's classification list includes BC-5 "Foundations" and BC-A residential, with BC-A/r capped at $125,000; which license fits a job is the Board's call. Under § 62-6-502(a), a business presenting itself to the public as doing home improvement work in these counties must follow the Home Improvement law, and § 62-6-136 makes it unlawful to pose as a licensed contractor, or act as one, without a license. Hence your own lookup, and this list:
- The number and the name. Look the license number up yourself; the name on the record should match the contract.
- One number, everywhere. Under § 62-6-503, a home improvement permit must list each contractor's Home Improvement license number, so permit and contract should match.
- A complete written contract. Under § 62-6-508 it holds the whole agreement in legible writing: parties, date, work, license number, start and completion dates, price and a notice that the Board must license contractors. Printed over the signature line: "Do not sign this contract if blank. You are entitled to a copy of the contract at the time you sign."
- Deposit and changes. State consumer guidance generally bars home improvement contractors from asking more than one-third of the price up front; added work gets a signed change order.
- Permit and engineer. Who applies for the permit, and whether a licensed professional engineer will go over the repair plan.
- Piers and trades. Pier number, type, depth and spots, and who does any plumbing or electrical piece (a locally licensed tradesperson).
- Warranty and references. Written warranty terms, whether they pass to a later owner, and local references.
Insurance and Foundation Repair
Only your own insurer can tell you what your policy covers, so put the question to it before any work begins. We don't answer policy questions.
How to Back Out After Signing
Tennessee's cancel right applies to home solicitation sales, meaning a sale made by a seller who comes to your home; it does not reach every contract. For such a sale, the state's consumer guidance lets you cancel up until midnight of the third business day following your signature on the agreement or offer to buy, and the seller then owes your refund within 10 days. Cash sales under $25 are excluded, and other exceptions may apply.
To cancel, do it in writing and keep a dated copy and proof of delivery.
The Tennessee Consumer Protection Act (§ 47-18-104) treats as unfair or deceptive, among other things, confusing people about who sponsors or is affiliated with a service, bait advertising, saying a repair is needed when it isn't, and passing oneself off as a licensed contractor. Sales-practice complaints belong with the Tennessee Division of Consumer Affairs, license questions with the Tennessee Board for Licensing Contractors.
Engineer Letters and Permits
Inside Chattanooga, TN city limits, the City's Land Development Office handles building permits, plans review and inspections, including structural reviews. Its Residential Building Permit is for new single-unit homes, ADUs and "work altering the existing footprint." Its Residential Modification Permit covers "modifications to existing structures that don't alter the footprint," porch repair and re-roofing among its examples. Neither names foundation repair, so ask the specialist which applies and confirm with the office (listed below). An owner may pull a City permit as their own contractor unless issued an owner's permit in the past 24 months.
For homes outside any city's limits, Hamilton County Building Inspection says: "A building permit is required for any new, alteration, addition or repair to a structure." An owner can buy a County permit for the home they live in, one residence every two years, with a State Homeowner Affidavit; anyone they hire is still bound by license rules. In East Ridge, TN, the City's permit list includes "alterations, repairs, or additions to existing buildings or structures," and its one engineer rule reads: "Retaining walls four or more feet high require an engineer's stamped drawing." It applies to retaining walls alone.
We found no engineer rule for foundation repair either way; the FAQ below has the two questions to ask.
- The ground. USGS lists the Valley and Ridge among Tennessee's karst regions, and TEMA advises learning whether a property is near steep slopes, sinkholes or unstable ground. Note any hole or dip in the yard in your request, and ask whether a geotechnical professional or licensed professional engineer should examine it first.
- Plumbing and electrical. Around Chattanooga, TN these trades are licensed and permitted locally; East Ridge, TN has its trade permits "pulled by a licensed contractor." We offer neither.
- Flood zones. If the property lies in a mapped flood zone, check with the permit office about any added review.
Your Local Building Department
Most often the contractor applies for the permit; still, ask the specialist who will. Chattanooga, TN and Hamilton County let an owner pull one for their own home, within the limits above. Each office sets its own process; Chattanooga's never carries over to a neighbor.

Foundation Rules FAQ
Where do I take a complaint about a contractor?
Sales-practice problems go to the Tennessee Division of Consumer Affairs; questions about a business's license standing go to the Tennessee Board for Licensing Contractors, and verify.tn.gov shows any license record. We sign no contracts with homeowners, so we play no part in settling a dispute.
Does the Home Improvement license reach homes inside Chattanooga, TN city limits?
The Board's list names counties, not cities, so we describe the rule as applying in Hamilton County and Bradley County. Whether it reaches every address inside a given city is for the Board to answer; checking the number costs nothing.
Does my foundation job need an engineer?
No page we read settles that for foundation work, so we can't say. Before you sign, ask the specialist whether a licensed professional engineer will be part of the plan, and ask your permit office whether it wants a structural review. Keep both answers in writing.
I rent the house out. Does any of this change?
With 52.4% of Chattanooga, TN homes owner-occupied (Census QuickFacts), many are rentals. The Board's definition covers residential buildings of one to four units, so the same license questions apply to a landlord, and so does the permit question.
