Converted our garage into a full ADU and it’s now a great rental unit. The construction quality is excellent—good insulation, nice finishes, and smart layout. The crew kept everything on schedule and communicated clearly throughout.
The ADU we built in the backyard is now my peaceful reading and hobby space. They did impressive work on the structure and interiors. It feels private yet connected to the main house.

Converted our garage into a fully functional ADU suite. Everything from the flooring to the electrical work was done right. The team was reliable and the final result looks fantastic.
The finished ADU conversion was done and completed on time as agreed, I somehow thought it would take forever but they walked the talk.

We renovated our master bathroom and the outcome is stunning. The walk-in shower and fixtures feel modern and luxurious. A1 ADU Contractor workers were respectful and very detail-oriented. We couldn’t be happier with the final result.
Homeowners in Tarzana are increasingly looking for practical ways to expand their living space without relocating. Whether it’s accommodating extended family, creating a private guest suite, or building a rental unit for additional income, a custom Accessory Dwelling Unit (ADU) offers a flexible solution. However, construction projects can quickly become overwhelming without experienced professionals managing planning, permits, and execution.
At A1 ADU Contractor, we provide custom ADU construction in Tarzana designed to deliver comfort, durability, and long-term property value. Our team handles every stage of the construction process with precision, ensuring your new living space is structurally sound, visually cohesive, and fully compliant with local building standards.
Constructing an ADU requires more than just adding square footage — it demands careful planning, quality materials, and expert craftsmanship.
Our Tarzana ADU construction services include:
Seamless integration with the primary residence design
Problem: Uneven terrain or soil conditions can affect structural stability. Solution: We conduct detailed site assessments and implement engineered foundation systems to ensure durability and safety.
Problem: Extending plumbing, electrical, and HVAC systems to a new structure can be complex. Solution: Our construction team coordinates utility expansion carefully to ensure efficient connections and future reliability.
Problem: Construction must meet strict local safety and zoning requirements. Solution: We follow approved construction plans precisely and adhere to all Tarzana building regulations to avoid setbacks.
Problem: A new ADU may look disconnected from the main home. Solution: We use complementary materials, finishes, and exterior details to create architectural harmony.
Our construction services cover every aspect of building a high-quality ADU from the ground up:
Each ADU we construct is built with attention to detail, focusing on strength, efficiency, and long-term performance.
We begin with an on-site evaluation to review access points, property layout, and construction logistics. This ensures a smooth building phase with minimal disruption.
Our skilled builders complete framing, roofing, mechanical systems, and interior installations according to approved plans and industry best practices.
We complete all finishes, conduct quality checks, and coordinate inspections to ensure the ADU is ready for safe occupancy.
