About Orange

Orange in numbers

Orange lies inside Orange County in California. Census figures put the town at about 138,728 residents and 44,336 households. 59 percent of occupied homes are owner occupied, and 25,828 of them are detached single family houses.

Work here is served from the Irvine office, about 20 minutes away at 13 miles. Orange County carries 563,953 detached single family homes in total, 56 percent owner occupied. Those households are roughly 4 percent of the Orange County total. Orange County holds about 3,164,063 people and 1,138,473 housing units in total. Half the housing predates 1972, and the 1960s were the busiest building years at 11,326 homes. A median home value of $848,200 and a median household income of $109,335 is what the American Community Survey records. Owners hold 26,103 of the occupied homes, renters the other 18,233. Roughly 68 percent of the housing here, 30,269 homes, went up before 1980, when footing drains and grade separations were not what they are now.

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

Local conditions

Why foundations move in Orange

The soil this town is built on

Mapped soil inside Orange 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. The texture split is 42 percent clay, 7 percent silt and 14 percent sand. Inside the Orange city limits, the USDA sample puts weighted linear extensibility at 3.24 percent, which is the figure USDA turns into a moderate shrink swell rating.

The housing stock

The 1960s put up more homes than any other decade, 11,326 of them, and the median year built is 1972. 30,269 of those homes predate 1980, which is where we most often find footing drains that were never installed and backfill that was never compacted. 21 percent of the housing here, 9,356 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. Of the owner occupied homes, 73 percent carry a mortgage.

Soil survey: USDA NRCS Soil Data Access (SSURGO), sdmdataaccess.nrcs.usda.gov.

Around Orange: Chapman University, Santiago Canyon College and Santiago Oaks Regional Park are all inside the city limits. They sit between 12 and 14 miles from our Irvine office.
