Angelus Construction – ADU Contractor in Los Angeles
Angelus Construction is a Los Angeles-based general construction company specializing in the design, permitting, and building of Accessory Dwelling Units (ADUs). With over 30 years of combined experience in residential and commercial construction, the team serves clients across Los Angeles and Ventura Counties.
The company is led by two partners — Elias Hermosillo and Luis Carmona — both licensed general contractors. Elias brings decades of experience in the union construction industry, having worked on notable projects in Los Angeles including the Disney Concert Hall and the Howard Hughes Center. Luis has been active in residential real estate development and construction since 2010, with a background that spans hillside foundation rebuilds, kitchen and bathroom remodels, HVAC installations, and full-scale renovations across a wide range of property types.
ADU Construction and Design Services
Angelus Construction offers a full-service approach to ADU projects, covering design, city permitting approvals, and construction from start to finish. They work with architects, engineers, and designers throughout the process to help keep projects on schedule and within budget.
The types of ADU projects they handle include:
- Detached ADU: A unit completely separate from the primary home, suitable for rental use while maintaining privacy.
- Attached ADU: A unit connected to the primary residence, offering a flexible way to expand living space and add a second unit.
- 2nd Floor / Garage Conversion: Converting or building above an existing secondary structure, including garage conversions where zoning permits.
Common ADU floor plan sizes they work with range from studio units of around 400 square feet to one-bedroom units of approximately 1,000 square feet, depending on the property and client goals.
Adding an ADU in Los Angeles can increase property value and create an additional income stream through rental revenue. With housing demand remaining high in the region, a well-built accessory dwelling unit can serve both practical and financial purposes for property owners.
Several factors can influence the overall cost of an ADU project, including:
- Site conditions — flat lot vs. hillside, and ease of material delivery
- Utility easements that may require mitigation
- Plumbing requirements, including sewer line distance and water main location
- Electrical panel capacity and whether an upgrade is needed
- Choice of finish materials such as flooring type, cabinetry, and countertops
- Setback requirements for garage additions or conversions
Angelus Construction offers a free initial consultation to assess the property, discuss goals, and provide a clearer picture of project costs before any commitments are made.
Their process follows three main phases:
- Initial Consultation: Understanding the client's goals and addressing questions or concerns.
- Design and Permitting: Finalizing plans, making revisions as needed, and submitting to the City of Los Angeles for approvals and clearances.
- Construction: Site preparation, rough and finish construction, inspector coordination, and project completion with a Certificate of Occupancy.

Beyond ADU construction, Angelus Construction also provides general residential remodeling and renovation services. Their work covers a broad range of projects, including:
- Kitchen and bathroom remodels
