The Maryland State Clean Indoor Air Act (CIAA): A Guide for the Public

The Clean Indoor Air Act of 2007 prohibits smoking in virtually all indoor workplaces in order to “preserve and improve the health, comfort, and environment of the people of Maryland by limiting exposure to environmental tobacco smoke.”

The law provides for fair and consistent statewide protection from exposure to secondhand smoke in indoor settings. People in Maryland will now have clean, smoke-free air while working, dining, shopping, or relaxing throughout the state.

What is covered under the CIAA Act?

As of February 1, 2008, there will be smoke-free air in almost all indoor places open to the public, including bars and restaurants.

The Act prohibits smoking in the following places:

  • Indoor areas open to the public
  • Indoor meeting places open to the public
  • Indoor places of employment
  • Mass transit vehicles
  • Private homes or residences being used by a licensed day care or child care provider
  • Private vehicles used for the public transportation of children or as part of health care or day care transportation
  • Clubs with alcohol licenses (under Article 2B, §1-102(a)(4), Annotated Code of Maryland)

How the CIAA is Enforced?

The CIAA is locally enforced by the Division of Environmental Health, Prince Georges County Health Department using County Regulations for enforcement within restaurants and bars and the State Clean Indoor Air Act for most other establishments. The Maryland Department of Health and Mental Hygiene Child Care Administration will be the enforcing agency for violations involving day care centers. For violations within a working place, MOSH will be the enforcing agency

Enforcement will be made through educational processes and through Letters of Reprimand and fines.

Please obey posted signs identifying areas where smoking is not allowed.

What is required of Businesses?

All businesses must prohibit smoking within their facilities. Signs stating that smoking is prohibited must be posted in the following facilities:

  • Retail stores
  • Concert halls
  • Financial service institutions
  • Educational institutions
  • Libraries
  • Clubs as defined in Article 2B §1-102(a)(4), Annotated Code of Maryland
  • Theaters
  • Athletic facilities
  • Government buildings

  • Hotels and Motels

Signs must be conspicuously posted at each entrance and in prominent locations inside the establishment.

Where Smoking is still allowed?

Smoking may still be permitted in public places like tobacco shops, outdoor areas of bars and restaurants, and up to 25 percent of a hotel’s or motel’s guest rooms. In addition, the Act does not ban smoking outdoors. However, some jurisdictions may have stricter ordinances and some specific businesses may be exempt or have a temporary waiver from some requirements of the Act. Look for signs in each establishment for guidance.
