Our Turnkey ADU Construction Services

We handle every stage of ADU construction to make the process straightforward for you. From the first look at your property to managing permits and keeping the schedule on track, our team covers all the key steps with care and precision.

Consultation and Assessment

We start by visiting your property to check the land, existing structures, and local zoning rules. This helps us understand space limits, possible challenges, and what kind of ADU fits best.


During this visit, we discuss your goals, budget, and timeline. We also explain any city rules that affect your build. This lets us create a clear plan that matches your needs and avoids surprises later.

Design and Permitting Process

Our designers create ADU plans based on your vision and site specs. We focus on making the most of available space while following local building codes and ordinances.


Once the design is ready, we handle permit applications with the city. This includes submitting all needed documents and communicating with city officials. We work to get approvals as quickly as possible to keep your project moving.

Project Management and Timeline Coordination

We organize the whole construction process from start to finish. That means scheduling crews, tracking materials, and solving problems fast.


Our project managers update you regularly about progress and timelines. We aim to finish work on schedule, coordinating all parts so nothing delays your new ADU.

Our Custom ADU Design Options

We offer different ADU design choices to fit various property types and needs. Our designs focus on making the best use of space, meeting local rules, and matching your home's style.

Detached and Attached ADUs

We design detached ADUs as separate small homes with their own entrances. These units provide privacy for renters or family members. They can range from studios to one or two bedrooms, depending on your lot size and local zoning.


Attached ADUs connect directly to your main house, often sharing a wall. This option saves space and can be more cost-effective. We make sure attached ADUs blend smoothly with your existing home.


Both options include modern kitchens, bathrooms, and living spaces. We handle permits and make sure your ADU meets city guidelines.

Garage Conversions

Garage conversions turn underused garage space into livable ADUs. This is a practical solution if you want to add living space without building new structures.


We assess your garage for layout, plumbing, and electrical needs. Our designs maximize natural light and ventilation. The converted space can serve as a rental, guest house, or home office.


We ensure the conversion fits local building codes and keeps your home's value. We also handle the necessary permits and inspections.

Multi-Unit Solutions

For bigger properties, we design multiple ADUs to increase rental income or house extended family. Multi-unit projects can include a mix of detached, attached, and garage conversion ADUs.


We plan layouts carefully to keep privacy and provide easy access. Shared utilities and parking are arranged to comply with regulations.


Our designs focus on efficient use of land while maintaining comfort and privacy for all occupants. We manage all steps from design to construction and permit processing.

Navigating Los Angeles ADU Regulations

Zoning and Compliance Strategies



Los Angeles has specific zoning rules for ADUs. We check if your property is in a zone that allows ADUs and verify lot size requirements. We also consider height limits, setbacks from property lines, and parking rules. Many areas allow ADUs without extra parking if public transit is nearby.


We review local ordinances to identify any special rules. For example, historic districts or coastal zones have extra restrictions.


By applying all this, we reduce risk of problems during construction. Knowing these details early saves time and money.


Permit Acquisition Support


Getting permits in Los Angeles can be complex and slow. We prepare all necessary documents, including plans that prove compliance with city codes.


Our team submits permit applications directly and communicates with city officials. We track progress to hasten approvals. We also handle revisions if the city requests changes. This keeps your project on schedule.


With our support, you spend less time worrying about paperwork. We make sure your ADU is approved and ready to build.
