City Housing Update for October 2021


Current Trends:

During this past month of September, the median rental price for a single family home in Costa Mesa was $3,426 and median sale price for a single family home in the city was $808,600. There were approximately 271 homes listed for sale in the city at the end of September, compared with 271 in August. During the last month, homes sold within 46 days on the market and received 1 offers per sale on average.


City Housing Supply:

As of the end of 2017, the total count of existing housing units in the city was 42,836. Single family housing units make up about 49.8% of Costa Mesa's housing units, 21,331 units total. Multifamily units make up 48 percent, or approximately 20,575. As of last year, the average housing density (people per household) was 2.74, compared with the state average of 2.97. At the end of the period, about 1,705 of housing units in the city were unoccupied, suggesting a vacancy rate of 0 percent.


Regulations & Outlook:

The City has not yet finalized updates to it's residential zoning code that fully comply with State Laws SB 1069 and AB 2299 which allow for Accessory Dwelling Units (ADUs) to be developed on most single family lots. More commonly referred to as “Granny Flats” and “In-Law Units”, in Costa Mesa as many as 12,585 homes may now be eligible to add some form of second dwelling unit. These laws are intended by The State to boost opportunities for housing production in cities in an effort to address the growing housing deficits local communities face accross The State. Typically secondary units are constructed by homeowners in backyards, converted garages and basements of single family residences. These new regulations could now allow individual homeowners to play a significant role to increase housing production in Costa Mesa over the coming years. Consider for example, if just one percent of eligible homeowners in Costa Mesa built an ADU each year, it would contribute an additional 629 units to the city's housing stock over the next five years and create hundreds of new local construction jobs.


Local News & Policy:

At this time, statewide standards will superseed any local residential zoning requirements for ADUs that are non-compliant with the state's minimum set of requirements. The current development standards for ADUs in Costa Mesa, or any other CA city, can be found at the city zoning page link and search below.
