Tennessee tenants are legally entitled to rental property that meets basic structural, health, and safety standards and is in good repair. If a landlord fails to take care of important maintenance, such as a leaky roof or a broken heater, you have several important legal rights, including:

the right to withhold rent until repairs are made, and
the right to “repair and deduct”—that is, to hire a repairperson to fix a serious defect that makes a unit unfit (or buy a replacement part or item and do it yourself) and deduct the cost from your rent.

Tennessee State and Local Law on Rent Withholding, Repair-and-Deduct, and Landlord Retaliation

For state law on rent withholding, see Tenn. Code Ann. § 68-111-104.

For state law on repair and deduct, see Tenn. Code Ann. § 66-28-502.

For state law prohibiting landlord retaliation, see Tenn. Code Ann. §§ 66-28-514, 68-111-105.

See the Laws and Legal Research section of Nolo for advice on finding and reading statutes and court decisions.

Also, check your local housing ordinances for any city or county rules that cover tenant rights when it comes to repairs. Contact your local building or housing authority. To find yours, call your mayor or city manager’s office or check your city or county website
