The City of Costa Mesa has created this page as a source of information regarding the City's regulation of group homes, including sober living homes, and certain state licensed facilities. The City seeks to ensure a balance between the needs of its residents, who wish to enjoy the peace and quiet of their homes in a traditional residential neighborhood and the needs of those living in residential recovery facilities to enjoy this same quality of life that Costa Mesa has to offer.


The City has invested considerable resources to achieve this balance, and in 2014 began to enact ordinances to ensure that all residents are able to enjoy Costa Mesa equally.  The City’s regulations for group homes, including sober living homes and state licensed alcoholism or drug abuse recovery or treatment facilities, are contained in Chapters XV and XVI of Title 13 (Zoning) and Article 23 of Title 9 (Licenses and Business Regulations)  of the Costa Mesa Municipal Code.  It should be noted that a sober living home is a home used by people recovering from substance abuse, which serves as an interim environment between rehabilitation and their future lives.  These homes are not allowed to provide the same services as a state licensed alcoholism or drug abuse recovery or treatment facility. Please note that under state law, the City does not regulate state-licensed residential care facilities or state-licensed drug and alcohol treatment facilities with 6 or fewer residents.

The purpose of these zoning and business regulations are to ensure that group homes are actually entitled to the accommodations provided under the City’s Municipal Code and are not simply skirting the City’s boarding house regulations.  The regulations are also intended to limit secondary impacts of group homes by reducing noise and traffic, persevering safety and providing adequate off-street parking.  The regulations provide an accommodation for the handicapped that is both reasonable and that bears some resemblance to the opportunities afforded non-handicapped individuals to use and enjoy a dwelling unit in a residential neighborhood. Lastly, these regulations serve to provide comfortable living environments that will enhance the opportunity for the handicapped, including recovering addicts to be successful in their programs.

The Zoning code requires a group home or sober living home with six or fewer occupants that may otherwise be considered an unpermitted use may locate in certain residential land use designations with a Special Use Permit (SUP).  A Conditional Use Permit (CUP) is required for and may be granted to allow the operation of a group home, state-licensed residential care facility or state-licensed drug and alcohol treatment facility with seven (7) or more occupants in certain residential and planned development zones under conditions of the Zoning code. 

In addition to the aforementioned Zoning requirements, all non-state licensed group homes of 7 or more are subject to Title 9, Chapter II, Article 23 of the Municipal Code that set forth the application and approval of operator’s permit for group homes.

How to Report Concerns:

As noted, the City of Costa Mesa is committed to regulating group homes and sober living facilities pursuant to all applicable laws to ensure these facilities are operated professionally to accommodate individuals seeking assistance while striking a balance to preserve the characteristics of residential neighborhoods for the enjoyment of all residents.  In this spirit, if you are a resident or property owner impacted by a zoning violation or nuisance associated with a group home or sober living facility you can contact the Community Improvement Division at (714) 754-5623 or online using My Costa Mesa (Report Issues). Once a Code Enforcement officer receives a complaint, an investigation will commence to determine whether or not there was or is a municipal code violation.

An investigation requires that the Code Enforcement officer follow strict guidelines in order to obtain evidence that would support the existence of a code violation. In general, when investigating certain types of claims, evidence is easily attainable because it is in plain sight and or tangible. In other situations, evidence is not easily attainable, and in these situations, the City requires help from the complaining party because he/she may be a witness or have evidence.  In these cases, the City has developed a nuisance logging procedure to keep track of evidence. The City’s Public Nuisance Information and Submittal Procedure can be found online. 

Additional investigative resources separate and apart from the City of Costa Mesa have been established by the Orange County District Attorney’s Office and the California Department of Health Care Services.

In June 2018, the Orange County District Attorney announced the formation of a Sober Living-home Investigation and Prosecution (SLIP) task force to investigate reports of criminal and civil violations related to and surrounding sober living homes and addiction and treatment or recovery centers.  The SLIP task force maintains a 24-hour telephone hotline at (714) 647-3228 and an online “Sober Living Home Investigation and Prosecution Program Referral Form.”

The California Department of Health Care Services ensures the provision of quality treatment through the enforcement of standards for professional and safe treatment. The Department of Health Care Services investigates complaints against California's alcohol and other drug recovery and treatment programs. The compliance division also investigates violations of the code of conduct of registered or certified alcohol and other drug counselors.  Alcohol or Drug Abuse Recovery or Treatment Facilities licensed or certified by the State are required to report counselor misconduct to the State within 24 hours of the violation.
