My tenants are complaining about secondhand smoke. What can I do about it until the smoke-free policy goes into effect?

Ask tenants to smoke outside or away from the building. You could try to reduce the secondhand smoke drifting between your tenants’ units by sealing the units off or by improving the ventilation but be aware that neither will eliminate the problem. The Fair Housing Act may require that residents with disabilities made worse by exposure to secondhand smoke be reasonably accommodated.
