Title 6 — HEALTH AND SAFETY Chapter 6.04 - ALAMEDA COUNTY FIRE CODE
Chapter 6.74 — PROHIBITION ON SMOKING IN AND AROUND MULTI-UNIT RESIDENCES
Alameda County Municipal Code · 2026-09 edition · updated 2026-10-01 · Alameda County
6.74.005. - Findings and declaration.¶
The Board of Supervisors of the County of Alameda finds and declares that:
A.
Secondhand smoke has repeatedly been identified as a health hazard.
1.
The U.S. Surgeon General concluded there is no risk-free level of exposure to secondhand smoke.
2.
The California Air Resources Board categorized secondhand smoke as a toxic air contaminant, along with most toxic automotive and industrial air pollutants, for which there is no safe level of exposure.
3.
The California Environmental Protection Agency (EPA) included secondhand smoke on the Proposition 65 list of chemicals known to the State of California to cause cancer, birth defects, and other reproductive harm.
4.
The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) recommends that multiunit housing be free from secondhand smoke, cannabis smoke, and aerosol from electronic smoking devices.
5.
The American Heart Association has recommended all adults and children be protected from smoking in multiunit housing.
B.
Exposure to secondhand smoke causes death and disease.
1.
Since 1964, approximately 2.5 million nonsmokers have died from health problems caused by exposure to secondhand smoke.
2.
Secondhand smoke was responsible for an estimated thirty-four thousand (34,000) heart disease-related and seven thousand three hundred (7,300) lung cancer-related deaths among adult nonsmokers each year during 2005-2009 in the United States.
3.
Exposure to secondhand smoke increases the risk of coronary heart disease by twenty-five (25) percent to thirty (30) percent and increases the risk of stroke by twenty (20) percent to thirty (30) percent.
4.
Secondhand smoke kills more than four hundred (400) infants every year.
C.
Electronic smoking device aerosol may be considered a health hazard.
1.
Research has found at least ten chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm, such as formaldehyde, acetaldehyde, lead, nickel, and toluene.
2.
Electronic smoking device aerosol is not harmless water vapor as it contains varying concentrations of particles and chemicals with some studies finding particle sizes and nicotine concentrations similar to, or even exceeding, conventional cigarette smoke.
3.
Evidence continues to build that exposure to electronic smoking device aerosol, including secondhand exposure, has immediate impacts on the human respiratory and cardiovascular systems, and thus likely poses a risk to human health.
4.
Given the increasing prevalence of electronic smoking device use, especially among youth and young adults, widespread nicotine exposure resulting in addiction and other harmful consequences is a serious concern.
5.
A number of health authorities, including the U.S. surgeon general, ASHRAE, and State of California's Tobacco Education and Research Oversight Committee (TEROC) all support inclusion of electronic smoking devices in regulations of smoking and other tobacco product use.
D.
Secondhand cannabis smoke is a health hazard.
1.
The California EPA included cannabis smoke on the Proposition 65 list of chemicals known to the State of California to cause cancer;
2.
Cannabis smoke contains at least thirty-three (33) known carcinogens;
3.
In one study, exposure to cannabis smoke in an unventilated setting resulted in detectible levels of cannabinoids in nonsmoker participants' blood and urine, and participants experienced minor increases in heart rate and impaired cognitive performance; and
4.
A recent systematic review of the literature concluded that secondhand exposure to cannabis smoke leads to cannabinoid metabolites in bodily fluids and individuals experiencing self-reported psychoactive effects.
E.
Nonsmokers who live in multiunit dwellings can be exposed to neighbors' secondhand smoke.
1.
Several peer-reviewed studies on drifting secondhand smoke in multiunit housing have confirmed that secondhand smoke transfers between units, seeping into smoke-free areas from areas where smoking occurs.
Residents of multiunit housing have higher levels of cotinine (a biomarker for nicotine) in their blood and saliva than those living in detached houses.
3.
Twelve (12) peer-reviewed journal articles have found that between twenty-six (26) percent and sixty-four (64) percent of residents of multiunit housing report secondhand smoke drifting into their home.
4.
Between forty-four (44) percent and 46.2 percent of Californians living in multiunit housing with personal smoke-free home policies are exposed to secondhand smoke in their home.
5.
Surveys have found that sixty-five (65) percent to ninety (90) percent of multiunit housing residents who experience secondhand smoke in their home are bothered by it.
F.
Harmful residues from tobacco smoke can be absorbed by and cling to virtually all indoor surfaces long after smoking has stopped and then be emitted back into the air, making this "thirdhand smoke" a potential health hazard.
1.
Thirdhand smoke contains carcinogenic materials that accumulate over time, presenting a health hazard long after the initial smoke is gone.
2.
A study found that thirdhand smoke remains months after nonsmokers have moved into units where smokers previously lived.
3.
Human exposure to these thirdhand smoke carcinogens can occur through inhalation, ingestion, or skin absorption through contact with carpeting, furnishings, or clothing.
4.
Thirdhand smoke potentially poses the greatest danger to infants and toddlers, who crawl on rugs and furnishings and place household items in their mouths.
5.
Nonsmoking people who are exposed to thirdhand smoke have significantly higher nicotine and cotinine levels than those who have not been exposed to thirdhand smoke.
6.
Research has shown that thirdhand smoke damages human cellular DNA.
G.
The Surgeon General has concluded that eliminating smoking in indoor spaces is the only way to fully protect nonsmokers from secondhand smoke exposure, and that separating smokers from nonsmokers, cleaning the air, and ventilating buildings cannot completely prevent secondhand smoke exposure.
H.
Secondhand smoke exposure in multiunit housing contributes to tobacco-related health inequities. For example, in California, when compared with adults who live in single-family homes, adults who live in multiunit housing are more likely to be:
1.
People of color (sixty-three (63) percent of residents of multiunit homes versus 49.6 percent of residents of single-family homes);
2.
Lower-income or below the poverty line (46.8 percent versus twenty-seven (27) percent);
3.
Lacking a high school diploma (21.4 percent versus 14.8 percent);
4.
Current smokers (17.5 percent versus 13.2 percent);
5.
Uninsured (23.4 percent versus 14.2 percent).
I.
Secondhand smoke in multiunit housing is a significant threat to the health and safety of California children.
1.
About a quarter of those who live in multiunit housing (25.2 percent) are under the age of eighteen (18).
2.
The home is the primary source of secondhand smoke for children.
3.
Fifty-six (56) percent of youth living in apartment units in which no one smokes have elevated blood cotinine levels above 0.05 ng/mL, indicating they have been exposed to potentially dangerous levels of
secondhand smoke.
4.
Children who live in apartments have mean cotinine levels that are forty-five (45) percent higher than cotinine levels in children who live in detached homes.
J.
A majority of multiunit housing residents, including a large portion of smokers, support smoke-free policies in multiunit residences.
1.
Seventy-four (74) percent of United States adults surveyed favor smoke-free public housing.
2.
Sixty-one (61) percent of Californians surveyed favor limiting smoking inside apartment units and sixty-nine (69) percent would support limiting smoking in outdoor common areas of apartment buildings.
3.
Almost three out of four (seventy-two (72) percent) Eden area residents strongly support or support a smoke-free policy for where they live.
