Custom Homes Built With Santa Ana in Mind
Santa Ana has character. The neighborhoods here have history, and the families that call this city home have roots.
Building a new home in a place like this takes more than just construction know-how. It takes an understanding of the community, the local permitting environment, and what homeowners in Orange County want from their living spaces.
That’s the work we do at Cornejos Builders.
We bring together skilled trades, solid materials, and a home-building process that keeps you informed and in control from the first conversation to the final walkthrough.
Every project we take on starts with your vision. Floor plan choices, square footage, energy-efficient windows, finishes, and layout all come from you. We’re here to make sure that vision becomes something you can actually live in, and love living in.

Ronda Welker
We couldn’t have asked for a better contractor to work with than Alex. We were needing our home remodeled in a very short window of time and Alex and his crew were always on schedule and in touch with us throughout the whole remodel. We would definitely use them again.

How Much Does a Home Builder Cost in Santa Ana, CA?
Building a new home is one of the most significant investments a family makes, so let’s be straightforward about the numbers.
Based on past project estimates, a new custom home in the Santa Ana area starts around $175,000 on the lower end when utilities are already connected, and can reach $450,000 or more for larger, higher-spec builds.
But here’s the honest truth: we can’t give you a meaningful number without knowing your vision. We always encourage homeowners to reach out with their specifics so we can get them an accurate quote.
Five Factors That Affect the Cost of Your Build
- Size and square footage: More space means more materials, more labor, and more time. A 1,200-square-foot home and a 2,800-square-foot home aren't in the same conversation, price-wise, even if they're on the same street.
- Lot conditions and site preparation: Some properties in Santa Ana come with sloped terrain, older utility infrastructure, or soil conditions that require additional work before we can break ground. That prep work factors into the overall cost.
- Materials and finishes: A home built with standard-grade fixtures and one built with high-end cabinetry, custom tile, and premium energy-efficient windows are going to land at very different numbers. We'll help you find the right balance for your budget.
- Design complexity: Open-concept layouts, vaulted ceilings, custom staircases, and architectural details add both character and cost. Simpler floor plans generally cost less to execute. More ambitious ones take more time and skill.
- Permitting and local requirements: Orange County has its own set of building codes and permitting requirements, and navigating those correctly matters. We handle all of that on your behalf, but it's a real factor in the total budget.
