About Costa Mesa

What Costa Mesa looks like from the truck

Costa Mesa is a Orange County town in California. About 111,490 people live here, across roughly 41,407 households. 40 percent of occupied homes are owner occupied, and 17,155 of them are detached single family houses.

Jobs run out of the Irvine office, 11 miles up the road and about 20 minutes out. Orange County carries 563,953 detached single family homes in total, 56 percent owner occupied. That is about 4 percent of every housing unit in Orange County. Orange County as a whole is about 3,164,063 people and 1,138,473 housing units. 11,206 homes went up in the 1960s, more than in any other decade, and the median build year is 1971. The Census puts Costa Mesa at a median home value of $959,800 and a median household income of $104,981. Owners hold 16,427 of the occupied homes, renters the other 24,980. Homes built before 1980 make up 74 percent of the stock, 30,811 in all.

Population and housing figures: American Community Survey, by way of the Signature Media market data set.

Local conditions

Why foundations move in Costa Mesa

Ground conditions

Mapped soil inside Costa Mesa is recorded as disturbed urban ground, so the soil series comes from the wider survey. Across Orange County the USDA survey is Cieneba at about 11 percent of the survey, with Myford and Calleguas alongside it. By texture that survey runs 42 percent clay, 7 percent silt and 14 percent sand. For swelling and shrinking, the city sample is the more specific reading. Inside the Costa Mesa city limits it gives a weighted linear extensibility of 5.38 percent, which USDA reads as moderate shrink swell potential.

What these homes were built like

The 1960s put up more homes than any other decade, 11,206 of them, and the median year built is 1971. Pre 1980 construction accounts for 30,811 homes here, and that is the group where original drainage is usually the story. 36 percent of the housing here, 14,985 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. Mortgages sit on 77 percent of the owner occupied homes in Costa Mesa.

What California customers say

Brian came out for a free consultation to see if our house had foundation issues. We were getting some cracking in our drywall and wanted to know if it was a settlement issue. Brian measured the various elevations in our house, both inside and outside. He also went down in the crawlspace to observe the foundation. He determined our house did not have a major settling issue. He was knowledgeable about expansive soil and we were able to pick his brain about the kind of soil our house was built on. He talked through potential soil strengthening solutions with us, but didn’t recommend any major work be done at the moment. This company has serious integrity- they come out for free, and then determine they are not needed for further work. I will be recommending them to friends who may have foundation issues!!

I had Dalinghaus Construction out for a free consultation to check out some cracks in my ceiling, which I feared were based on foundation issues. Tom came from California and was so thorough in examining everything, testing the level of the floor throughout the house, walking the perimeter, and checking for other symptoms. Luckily, it wasn’t a foundation issue. Even though it was a free consultation, I felt like I should pay because he was so thorough. It made me realize how much integrity this company has. I highly recommend this company as trusted professionals that have the competence and integrity to get the job done correctly. I hope I never have foundation issues, but I certainly know who to call if I do!
