Going smoke-free saves you money – and helps to save your building. Some interesting facts:
Risk of Fire. Landlords universally recognize the liabilities and hazards of having an indoor smoker as a resident. “I’ve had two places burn down because of cigarettes,” noted one landlord.

The number one cause of fire fatalities in Maryland is cigarette-related fires.
In 2007, careless smoking caused more fire deaths than fires resulting from all other causes. Fourteen cigarette-related fires claimed 25 fire victims, ranging in age from 2 years old to 28 years old. All 14 fires occurred in residential structures.
In Maryland, the fatality rate due to smoking is much higher than the national average – in 2007, cigarette-related fires caused 27% of all fire deaths in Maryland. Nationally, in 2002, only 4% of all residential fires were caused by smoking materials, but these fires are responsible for a disproportionate number of deaths (19%) and injuries (9%). The fatality rate due to smoking is nearly four times higher than the overall residential fire rate; injuries are more than twice as likely.

Maintenance Savings. Landlords experience a major problem with indoor smoking – the expense in time and materials to repair, refurbish, and otherwise clean up after tenants have smoked consistently in a rental unit. Smell, stains on walls, burns in carpets and countertops, and more smell. In addition to the smell and stains, there is permanent damage caused by careless stubbing out of butts and cigarettes left burning.
Landlords reported that preparing a unit for a new lessee can cost up to or more than double the amount when the previous tenant is an indoor smoker as compared to a non-smoker. In 2004-2005, the Sanford Housing Authority reported that on average, it cost $550 to prepare a nonsmoking unit for a new lessee compared to $1,070 – $1,670 to prepare a unit occupied by a smoker (statistics vary greatly according to the area of carpet, the amount of damage, etc.).
Improved Resale Opportunities. Recent research suggests that smoke-free apartment buildings may have increased re-sale value, should you ever decide to sell your building. Agents who have assisted people selling or shopping for everything from starter-home Capes to Victorian mansions, agree: as the number of public places in which a person can smoke has shrunk, so has the number of home buyers who are even willing to consider a house occupied by indoor smokers .

Along with significant risks of property damage in a building without a smoke-free policy, you are also vulnerable to lawsuits by nonsmoking tenants suffering from the effects of secondhand smoke.
