Our Efficient ADU Design-Build Process

Building an ADU is specialized work requiring a deep understanding of local codes. Our streamlined process ensures compliance and speed.

Feasibility & Zoning Review

We conduct a thorough site analysis and review all local zoning and setback requirements (crucial for ADUs) to determine the maximum size and location allowable on your specific lot.

Design & Permitting

We design the unit (detached, attached, or garage conversion) and produce all necessary architectural and engineering plans. We handle the submission and management of all city permits under the latest state laws to expedite approval.

Construction & Installation

The foundation is laid, framing is erected, and all mechanical systems (electrical, plumbing, HVAC) are installed. We work diligently to minimize disruption to your main residence.

Finishes & Handover

We install interior finishes, cabinetry, bathroom fixtures, and landscaping around the unit. After the final inspection, we provide you with a high-quality, move-in or rent-ready dwelling unit.

 Trustindex verifies that the original source of the review is Google. Don and his team did an amazing job on our kitchen remodel. We have a full house so this remodel worried me bc I was afraid of delays. However, from beginning to end, Don was very clear with his timeline and cost. He finished our kitchen in 3 weeks (1 week was my fault for the delay). He and his team were very respectful and cleaned up after themselves everyday which I appreciated so much since we had little ones running around. We also had Don’s team install a flip-out window which gave us additional seating space in our backyard for our guests. I’m very happy with the quality of their work and will def use them again when I’m ready for my bathroom remodel. Added before and after pics.

Frequently Asked Questions

What is the maximum size for an ADU?

In most of Orange County, state law allows for a detached ADU of up to 1,200 square feet, depending on your lot size and existing house size. We will verify the exact maximum size and setback requirements during our feasibility review.

How long does it take to build a detached ADU?

From initial design to final completion, a detached ADU typically takes between 9 to 15 months. This includes the critical 3-6 month period for obtaining city permits and plan checks.

Can I build an ADU on a property with an HOA?

While state law overrides many local zoning limitations, Homeowners Associations (HOAs) can still have rules regarding appearance and exterior materials. We help you navigate HOA restrictions and ensure the design meets their aesthetic requirements while maximizing your buildable space.

The Power of Building an ADU

An ADU is a strategic tool for homeowners looking to gain immediate utility and secure long-term financial benefits from their property.

Instant Income Stream

California's high rental demand makes ADUs a prime asset for generating passive income. We design units optimized for rental appeal, helping you offset mortgage costs, fund college savings, or simply increase monthly cash flow.

Multi-Generational Living

Provide a private, independent, yet close-knit living space for aging parents or adult children. An ADU offers the perfect balance of proximity and privacy, keeping family safe and connected.

Ultimate Flexibility

Whether you need a dedicated, sound-proof home office, a private gym, a guest house for visiting friends, or a studio for hobbies, an ADU delivers the separated, custom-designed space that your main house cannot.

Property Value Maximization

Adding a fully permitted, high-quality ADU is proven to significantly increase your property’s overall appraisal and market value, making it one of the most reliable home improvements you can invest in.
