About Premium ADU
Premium ADU is a Los Angeles-based company that specializes in designing and constructing Accessory Dwelling Units (ADUs) for homeowners across Los Angeles and the surrounding areas. Operating since 2021, they focus exclusively on ADU projects — from detached ADU builds and garage conversions to in-law suites and backyard cottages. Their work covers the full project lifecycle, including design, permitting, construction, and final inspection.
Unlike many general contractors, Premium ADU works with an in-house team rather than relying on subcontractors. This approach gives them more direct control over quality and scheduling throughout each project.
ADU Services Offered
Premium ADU handles a range of accessory dwelling unit types, tailored to the specific needs and property layout of each homeowner. Their services include:
- Detached ADU construction — standalone units built on the same lot as the primary residence
- Garage conversion — transforming underused garages into functional living spaces
- Attached and interior ADUs — converting existing rooms or basement spaces into independent units
- Junior ADUs (JADUs) — smaller units created within the existing footprint of a home
- Custom design and architecture — working with homeowners to develop a layout that fits their property and budget
Whether a homeowner is looking to house a family member, create a rental unit, or simply add usable space to their property, Premium ADU offers solutions ranging from compact studio layouts to more spacious multi-room configurations.
A notable part of their offering is garage conversion work. They convert seldom-used garages into livable spaces such as home offices, guest suites, or full residential units. This type of conversion can add meaningful value to a property without expanding its overall footprint.
The Building Process
Premium ADU follows a structured process designed to keep homeowners informed at each stage. The process generally includes:
- Free consultation — discussing the homeowner's goals, budget, and property
- Custom design — architects develop plans suited to the specific site
- Permits and approvals — Premium ADU manages the permitting process with local city and county authorities
- Construction — carried out by their in-house team
- Final inspections — ensuring the completed unit meets all applicable codes and regulations
Most projects are completed within 6 to 12 months, though timelines can vary depending on design complexity, permitting, and site conditions. The company emphasizes transparent communication throughout, aiming to reduce the administrative burden on homeowners.
Premium ADU also notes that they intentionally limit the number of projects they take on at any given time, with the stated goal of maintaining consistent quality rather than maximizing volume.
For homeowners considering the financial side of an ADU project, Premium ADU offers financing options and provides rough cost estimates based on unit size, type, number of rooms, and kitchen configuration. Actual costs will vary depending on specific project requirements.
ADUs can generally be used as rental properties, though homeowners are advised to verify any applicable local regulations or rental restrictions with their jurisdiction before proceeding.
