Who We Are
A Design-Build Firm With Deep Los Angeles Roots
Coast Builders Group is a full-service residential construction and architectural
design company based in Los Angeles. We're licensed architects, experienced
general contractors, and project managers who understand that building—or remodeling—your home is one of the most important investments you'll make.
Since our founding, we've completed 200+ residential projects across Los Angeles
County, from single-room renovations to complete custom homes. We're committed to delivering on time, on budget, and with the quality that reflects your investment.
More importantly, we're Los Angeles-based professionals with deep community ties.
We're vetted members of the Altadena Collective and the Altadena Chamber of
Commerce, which means we're accountable to the communities we serve and invested in Los Angeles's future.
Comprehensive Design & Construction Services
One Team, One Vision
Los Angeles Expertise & Community Accountability
We don't specialize in one thing—we excel at everything residential construction requires. Architectural design. ADU development. Kitchen and bathroom remodeling. Home additions. Hardscape construction. Interior design. We've built it all.
Our breadth of expertise means we understand how different project types integrate with your home's overall value and function. Whether it's your first consultation or your fifth project with us, you're working with professionals who've solved every problem.
You don't hire separate designers and contractors. That creates miscommunication, cost surprises, and design compromises.
At Coast Builders, our design team will imagine your project, and our construction team builds exactly what was envisioned. We're one company, one accountability, one commitment to your success. When design and construction are aligned, projects run faster, costs stay controlled, and quality improves.
Your project benefits from seamless communication, early problem-solving, and a single point of responsibility.
We're a Los Angeles-based firm committed to delivering projects that exceed expectations. We're vetted members of the Altadena Collective and the Altadena Chamber of Commerce, demonstrating our accountability and commitment to the communities we serve.
Our team has deep experience navigating Los Angeles permitting, understanding local regulations, and delivering projects that strengthen neighborhoods across the region. When you hire Coast Builders, you're working with professionals invested in your success.
Our Values
How We Work: Our Commitment to You
Transparency Above All
You deserve clear communication about timeline, budget, and what to expect. If challenges arise, we tell you immediately with solutions. No surprises. No hidden costs.
Quality is Non-Negotiable
We don't cut corners. Every project receives the same attention to detail, craftsmanship, and compliance—whether it's a $50K kitchen remodel or a $500K custom home.
One Team, One Responsibility
You have one point of contact. One company manages design, permitting, and construction. We're responsible for the entire outcome—not just our portion of it.
Respect for Your Investment
Your home is your largest investment. We treat it that way—protecting your property, respecting your timeline, and delivering results that increase your home's value and your quality of life.
Community Accountability
We're part of Los Angeles. We're accountable to our professional standards and the communities we serve.
