About Anaheim Master ADU Builders

Anaheim Master ADU Builders was founded in 2010 by a master builder and an architectural designer. They witnessed the growing demand for additional living space and the challenges homeowners faced with inexperienced contractors. They combined their expertise to establish a specialized ADU company built on principles of design excellence, construction integrity, and client education. What began as a small team focusing on garage conversions has evolved into Anaheim's most trusted full-service ADU contractor, with dedicated departments for design, permitting, construction, and interior finishing.


Our leadership team contributes over 25 years of collective experience in residential construction, architectural design, and California-specific ADU regulations. Our members hold multiple certifications including Certified Green Builder, California Building Performance Contractor, and maintain an active General Contractor's license with ADU specialization. Our architectural designers emphasize space optimization. Their certification in California ADU Code Compliance ensures every project balances aesthetic appeal with functional excellence while meeting all regulatory requirements.

Our headquarters and design studio are located in central Anaheim, allowing us to serve clients throughout the city with personalized attention. We maintain strong relationships with local planning departments, having successfully navigated the permitting process for over 200 ADUs across Orange County. Our active membership in the Anaheim Chamber of Commerce, National Association of Home Builders, and California ADU Coalition demonstrates our commitment to industry excellence and community involvement.


Our mission is to provide Anaheim homeowners with beautifully designed, expertly constructed ADUs that maximize property potential while delivering an exceptional client experience from initial concept through completed construction. We believe that a superior ADU requires thoughtful design, quality materials, precise construction techniques, and ongoing support. We measure our success by our clients' satisfaction and the transformative impact our ADUs have on their properties and lives.
