Spray Foam Genius Marketing helps spray foam and insulation contractors in Costa Mesa, California win more jobs from homeowners and builders searching in that market. What follows is a local reading of the same Census, climate, and housing lines printed in the cards. The climate zone on this page is 3B. The population line reads 108,881. If a line is missing, this section does not fill it in.
The climate figure for Costa Mesa is zone 3B. Quoted from the note: dry climate, zone 3 of 8. The moisture letter on this zone is dry (3B). Source on this page: U.S. DOE and PNNL, Guide to Determining Climate Zone by County: Building America and IECC 2021 Updates (PNNL-33270), as of October 21, 2022. A page written for a different zone will talk about the wrong season. Match the services on the website and the Google Business Profile to this zone.
Nothing here is a ranking promise. It is a way to order the Costa Mesa message. Heating is the larger degree-day number, so cold-weather comfort is the first story for Costa Mesa. With owner-occupancy at 37%, a Costa Mesa campaign that speaks only to resident homeowners is aimed at the smaller tenure group. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.
On the population line, Costa Mesa shows 108,881. The note on that line says: Estimate for July 1, 2025. Source on this page: U.S. Census Bureau, Vintage 2025 population estimates for cities and towns, as of July 1, 2025. The county line reads Orange County. Use the city total as context. The audit grid, not the census count, is what shows where a company actually appears.
Median home value in Costa Mesa is $1,166,800. That is higher than the national figure of $360,600 in the same note. The note on that line says: Owner-occupied homes. National: $360,600 (survey estimate). A higher or lower value is not a price you should promise for a job. It is a clue about which message to lead with, comfort and performance or straightforward savings, and it stays tied to the survey year.
A typical year, as printed here, needs 1,092 heating degree days and 1,075 cooling degree days. Both figures use base 65 F. Heating (1,092) is larger than cooling (1,075). The heating note says the reading was measured at SANTA ANA JOHN WAYNE AP. Pages and ads can lead with cold rooms, drafts, and heating bills. Do not copy a cold-climate service list onto a cooling-led city, or the reverse.
The pre-1980 housing line for Costa Mesa reads 62%. That share is higher than the national figure of 48% in the same note. Source on this page: U.S. Census Bureau, 2024 American Community Survey 1-year estimates, table B25034, as of 2024. Write about air sealing and attic work for those houses only in the terms you can actually explain. The statistic does not say which neighborhoods hold the older homes.
When the site talks about old houses versus new ones in Costa Mesa, the sourced median is 1975. That year is earlier than the national median of 1981 printed in the same note. Source on this page: U.S. Census Bureau, 2024 American Community Survey 1-year estimates, table B25035, as of 2024. Do not turn the median into a claim that most homes were built in that exact year. A median is the midpoint of the survey, and the note says it is a survey estimate when that is what the source published.
Costa Mesa shows 37% owner-occupied. That is lower than the national figure of 65% in the same note. Source on this page: U.S. Census Bureau, 2024 American Community Survey 1-year estimates, table B25003, as of 2024. The city figure is under half, so renters are a large part of occupied homes. Renters are less often the person who hires insulation, which makes owners and landlords the tighter audience. Do not read the percentage as a market-share goal. It is a housing tenure figure from the source named on the card.

What this means for your marketing in Costa Mesa
37% of occupied homes in Costa Mesa are owner-occupied (nationally: 65%), and the median home value is $1,166,800 (nationally: $360,600). Renters make up a large part of the city, and renters are less often the ones who commission insulation work, so the buyers you want are a smaller group of owners and landlords. It is worth checking in your Google Maps grid whether the strongest demand sits in the suburbs and towns around the city. Higher home values tend to go with owners who spend on comfort and performance, so quality, warranty and results messaging usually works better than leading with price.
Costa Mesa is in Orange County, which falls in IECC climate zone 3B. NOAA's 1991-2020 normals for SANTA ANA JOHN WAYNE AP (about 3 miles away) show 1,092 heating degree days and 1,075 cooling degree days in a typical year, so heating and cooling both matter. For a spray foam or insulation contractor, demand is not tied to one season: searches can be about summer attic heat or winter drafts and heating bills, so pages and ads that cover both work better than one seasonal message. The "B" in 3B marks a dry climate, so the story is mostly temperature and energy bills rather than humidity.
The Census Bureau's 2024 American Community Survey puts the median home in Costa Mesa at a build year of 1975 (nationally: 1981), and 62% of its homes were built before 1980 (nationally: 48%). That is an older housing stock. Older homes are where attic insulation, air sealing and rim joist work tend to pay off for the owner, so retrofit and energy-bill messaging usually fits better here than a new-construction pitch.
Costa Mesa had an estimated 108,881 residents on July 1, 2025 (U.S. Census Bureau). Google Maps rankings change from one part of a market to the next, so being visible near your shop does not mean being visible across the whole service area. The free Market Visibility Audit shows your ranking at a grid of points around your business.
How the Google Maps grid works in a market like Costa Mesa
Google Maps does not show one ranking for a whole city. The result changes block by block, depending on where the searcher is standing. Our audit searches from a grid of points around your business and records where you appear at each one. Green means you are in the top 3 at that spot. Red means customers there are not finding you. Run it for the Costa Mesa service area you want. A good result next to the office can sit beside a miss a few miles away.

4. Monthly review
Each month we review what is live: the map listing, the pages, and the ads. We do not bill per lead or per estimate.
