No Smoking Clause in Lease Agreement

[Samuel Botts]

Does anyone know if there are any laws preventing a landlord to have a no smoking clause in the lease agreement? I have a copy of the LL/Tenant Law Handbook for Georgia, this is where my rental property is located, but there is no mention at all of whether or not a landlord can prohibit a tenant from smoking. So I know that I'm fine at the state level. However, I cannot find any landlord/tenant laws for Douglas County specifically (property is in Douglasville). I want to prohibit any smoking in the unit but obviously want to be compliant with the law. The unit is an SFH 3/2.

Thanks in advance for any help.
