How We Simplify Your ADU Project from Start to Finish


Building an accessory dwelling unit involves multiple stages, and we manage each one with precision and transparency. From the initial consultation through final walkthrough, our team coordinates every detail so you can focus on your vision while we handle the complexities.


Comprehensive Design and Planning Services


We begin every project with a thorough site evaluation and consultation to understand your goals, whether you're building a rental unit, creating space for aging parents, or adding a home office. Our design team creates detailed plans that maximize your lot's potential while respecting setback requirements, utility access, and neighborhood aesthetics. We present 3D renderings and floor plans that help you visualize the finished product before construction begins. Throughout the design phase, we incorporate your feedback and adjust layouts to ensure the final ADU meets your specific needs and budget parameters.


Navigating Permits and Approvals


The permitting process for ADUs in Anaheim requires careful attention to zoning laws, building codes, and city-specific requirements. We prepare and submit all necessary documentation to the city, including architectural plans, structural calculations, and utility connection proposals. Our familiarity with local building department procedures helps avoid delays and ensures compliance with fire safety standards, energy efficiency requirements, and accessibility guidelines. From foundation inspections to final occupancy approval, we coordinate with city inspectors and address any questions or modifications promptly, keeping your project on schedule.


Quality Construction and Project Management


Once permits are secured, our construction crews begin work with a clear timeline and regular communication. We handle foundation work, wall framing, electrical and plumbing installations, and all finish carpentry with skilled tradespeople who take pride in their craftsmanship. Our ADU framing, roofing, siding, and drywall work meet the highest standards for durability and weather resistance, ensuring your new structure stands strong for decades. Daily site supervision and quality checks at each construction phase guarantee that work meets both building codes and our internal quality standards, with minimal disruption to your daily routine.


Our Commitment to Energy-Efficient and Comfortable ADUs


We build accessory dwelling units that prioritize both comfort and long-term cost savings through smart material choices and construction techniques. Every ADU we construct incorporates features that reduce energy consumption while creating a pleasant living environment.


Advanced Insulation and Climate Control


Proper insulation makes a dramatic difference in your ADU's comfort and utility costs throughout Southern California's varied seasons. We install high-performance insulation in walls, ceilings, and floors that maintains stable interior temperatures year-round. Our ADU soundproofing and insulation techniques include acoustic batts in shared walls and specialized materials that minimize noise transfer between the main house and accessory unit. Spray foam insulation in rim joists and air sealing around penetrations prevent drafts and moisture intrusion. We also ensure proper ventilation systems that provide fresh air circulation without compromising energy efficiency, creating healthier indoor air quality for occupants.



Modern Building Systems and Fixtures


Each ADU we complete features energy-efficient windows with low-E coatings that reduce heat gain while providing natural light. We install LED lighting throughout, programmable thermostats for HVAC systems, and low-flow plumbing fixtures that conserve water without sacrificing performance. Electrical systems are designed with future needs in mind, including capacity for electric vehicle charging or solar panel integration. Durable exterior materials resist East Anaheim's sun exposure and occasional weather events while requiring minimal maintenance over time.


Sustainable Material Selection


We source building materials that combine environmental responsibility with longevity and aesthetic appeal. From sustainably harvested lumber to recycled-content insulation and low-VOC paints, we select products that contribute to healthier indoor environments. Our finish options include a range of flooring, cabinetry, and countertop materials that suit different styles and budgets while meeting California's strict environmental standards for residential construction.

Transparent Communication and Realistic Timelines

Our project managers update you on progress, address questions promptly, and alert you immediately if any unexpected conditions arise that might affect the timeline or budget. We set realistic completion dates based on actual construction schedules and permit processing times rather than overpromising to win your business.
