Finding a local home builder company in Santa Fe Springs, CA, shouldn’t feel like a gamble. With the right team, building a home is one of the more straightforward things you’ll do as a property owner.

Santa Fe Springs sits in that pocket of Southeast LA County where lots come in every shape, neighborhoods carry real character, and the homeowners who build here tend to be the kind who plan to stay. A custom home in this part of the metro should reflect that.
The design has to make sense for the lot, the construction has to hold up to decades of Southern California living, and the experience along the way needs to be one you actually enjoy. That’s the gap Cornejo’s Builders has been filling across LA and Orange County. Alexsander runs the company personally, which is something every client mentions in their reviews, usually right after they note that he was on-site frequently throughout their build.
The crew works in-house, the materials come from the biggest names in the industry at better rates than most outfits can offer, and the project manager assigned to your build is there every single day until you’re holding the keys.
Twenty-four ADUs in four years, dozens of full home builds, and a process that takes you from first phone call to move-in without any of the chaos that gives custom construction its bad reputation.


Alexsander Cornejo – Owner of Cornejo Builders
Hi, I’m Alexsander Cornejo, the owner and founder of Cornejo’s Builders. I started working in the remodeling and construction industry right out of high school, in 2009.
With Cornejo’s Builders, the goal is to give back to the city I grew up in. I want to send a message of hope and inspiration: any dream can be achieved, no matter where you come from, if you put in enough work and dedication.

Recent examples from our work across the region:
Your specific number depends on the lot, the size, and the level of finish you’re after. Call (562) 319-3178 or send a note through our contact page for an on-site assessment and a real quote.
1. Square Footage and Floor Plan
A compact 800 square foot footprint costs significantly less than a 2,000 square foot custom build. Layout complexity, the number of bathrooms, and any multi-story design choices also play into the labor and material totals
2. Site and Foundation Work
Every home starts with a new foundation, and the prep work below grade can vary widely depending on the lot. Soil conditions, drainage planning, and any grading needed all factor into the early-stage budget.
3. Mechanicals and Utilities
New plumbing, new electrical, HVAC sizing, and getting utilities connected to the site are non-negotiable line items. Mini-split systems, tankless water heaters, and other upgrades each add their own cost.
4. Finish Level
Level 5 smooth-finish drywall, curbless walk-in showers, premium cabinetry, heated floors, and integrated sound systems all push the per-square-foot cost up. The finishes are where most homeowners’ visions get expressed, and where the budget either holds or runs.
5. Permits, Plans, and Design
Architectural plans, structural engineering, city permits, and inspections all happen before construction begins. We handle the entire paperwork side, but the costs are real and accounted for in the proposal from the start.
