Georgia does not have statutes on rent withholding or repair and deduct remedies for tenants, but Georgia courts recognize a tenant's right to repair and deduct.
Courts in Georgia have held that when a landlord fails to respond to repair requests after a reasonable time, tenants can hire a competent repair person to perform the needed repairs. The cost must be reasonable, and the tenant may deduct the cost from the rent. It's a good idea to put your request in writing, keep all receipts and invoices, hire licensed workers if possible, and perform only needed repairs, not upgrades. For more information, see the Georgia Landlord Tenant Handbook, 2017, Georgia Department of Community Affairs.
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, visit State and Local Government on the Net's Georgia page, call your mayor or city manager’s office, or check your city or county website.
