Why Hillstar Construction
Hillstar Construction is a licensed and insured general contractor serving Los Angeles since 2010, with over 35 years of construction experience. We specialize in ADU construction, kitchen remodeling, bathroom renovations, home additions, roofing, concrete, and hardscape work.
Our team handles every phase of the project, from design and permits to construction and final completion. We focus on clear communication, transparent pricing, and consistent workmanship throughout the job.
We work directly with homeowners — not through layers of subcontractors — so the same team that meets you on day one is the team you talk to throughout the build. Our crew covers framing, electrical, plumbing, and finish work in-house, which keeps project quality and scheduling consistent from start to finish.
Every project goes through the full Los Angeles permit process. We prepare plans, submit to the city, coordinate with inspectors, and carry work all the way through final sign-off. Homeowners never have to navigate permits, code compliance, or inspections on their own.
ADU Construction in Los Angeles
An ADU adds private, self-contained living space to your Los Angeles property — detached, attached, garage conversion, or junior ADU. It's one of the most reliable ways to grow square footage, lift property value, and add rental income without buying more land. Hillstar handles design, permits, construction, and final inspection in-house.
- Value & Rental Income — Add resale value and steady monthly income in the LA market.
- Multigenerational Living — Private space for parents, adult children, or extended family.
- Full Permit Handling — Plans, LA permits, and inspections — handled by us.
We build all four LA ADU types — detached, attached, garage conversion, and JADU — and help you pick the right fit on the first site visit.
