ADUs in Los Angeles, CA
A growing family, an aging parent, or a monthly budget that needs more income often points to the same problem: a property with space that was never built to be lived in. Turning that space into a separate home takes more than a weekend of work, because a unit needs its own entrance, kitchen, bathroom, and connections to the utilities already serving the main house. Without a clear plan, the project can stall where structure, plumbing, and electrical no longer line up. A professional builder coordinates all of it so the result works as a real home.
The City of Los Angeles regulates ADUs through its own ordinance, which covers accessory dwelling units, junior accessory dwelling units, and movable tiny houses. Its building department describes an ADU as a small, separate living space that can be attached to the main house or built as a separate structure, such as a converted garage or a backyard cottage. For an owner, that means the options on a single lot go beyond one kind of backyard unit, and the right one depends on the existing house, the yard, and what the space is meant to do. Sorting out which type fits is the first practical decision in any project.

About Los Angeles, CA
Los Angeles is the largest city in California and the county seat of Los Angeles County, with a coastline on the Pacific Ocean and the Santa Monica Mountains running along its northern side. It is a city of many distinct neighborhoods, each with its own streets, housing styles, and local character, from hillside lanes to flat boulevards lined with shops and apartments.
Those neighborhoods range from dense areas such as Downtown and Koreatown to residential communities like Silver Lake, Sherman Oaks, and Westchester, where many streets are lined with single family homes. Major freeways including the 405 and the 10 connect these communities to one another and to the wider region's job centers.
Griffith Park, the beaches along the coast, and the Los Angeles River corridor give residents plenty of open space to enjoy. The warm, dry climate keeps backyards, patios, and hillside trails in use well beyond the summer months, which makes outdoor living a regular part of daily life for many households.
What Los Angeles Plan Review Means for an ADU Build
Plans prepared by private architects and engineers can be approved in advance by the city's building department, and using one of these standard plans shortens the plan check review that an ADU project goes through. For an owner, that is a practical middle path between a blank page and a ready made layout.
An approved plan does not replace a review of the actual lot, though. The building department still checks that the design fits the property, follows zoning codes, and meets the foundation needs of the site. The shape of the yard, the position of the main house, and the ground the unit will sit on all influence which plan works.
State law sets the broad framework for ADUs in California, but local agencies keep discretion over their own policies. Here, that framework is carried out through the city's ADU ordinance, so an owner planning a unit should look to those rules, and to a builder who works within them, rather than to general advice about ADUs elsewhere.

What to Know Before Building an ADU on Your Property
Start with a clear answer to how the unit will be used. A space meant for tenants has different priorities than one meant for a parent, a grown child, or occasional guests, and those priorities affect privacy, entrances, parking, and how much living space the unit needs. Settling this early keeps the design focused.
Next comes choosing what kind of unit fits the property. Some owners convert an existing garage or part of the house, while others build a new backyard cottage or an addition attached to the main home. Each option has a different effect on the yard, the existing structure, and the utilities, which is why a walkthrough of the property comes before any drawings.
After that, the project moves through design, plan approval, construction, and finishing. A well planned ADU should feel like a complete home, with a kitchen, a bathroom, a sleeping area, and its own entrance. Asking a builder how each stage will be coordinated, and who you will be speaking with along the way, reveals a lot before work begins.

Frequently Asked Questions
1. What kinds of ADUs can be built on a residential lot?
The city describes an ADU as a small, separate living space, either attached to the main house or built as a separate structure like a converted garage or backyard cottage. We can walk your property and discuss what suits it.
2. Can an ADU be used for rental income or for family members?
Yes, an ADU can serve several purposes. Owners build them to generate rental income, host guests, or make room for extended family. We design each unit around your intended use so the layout works for whoever will live there.
3. Will a standard plan work for every property?
Not automatically. The city approves standard plans in advance, but the building department still reviews each project to confirm it fits the lot, follows zoning codes, and meets foundation needs. Your property decides which approach makes sense.
4. What should I decide before our first meeting?
Think about who will live in the unit, how private it should feel, and where it might sit on your property. Photos of your yard and a short wish list help us give useful guidance from the start.
5. Does an ADU have its own kitchen and bathroom?
A fully functional ADU is a complete home, so it includes its own kitchen, bathroom, sleeping area, and entrance. We plan those spaces together with the utility connections to the main property, so the unit feels self contained and comfortable.
6. Who will lead my ADU project?
Charlie Petrucci leads High Power Construction, and our team handles the design and build process together. That means you work with one company from planning through completion, with clear communication at each stage and a direct line to the people doing the work.
7. Can I combine an ADU with other work on my home?
Often, yes. We also handle remodeling and home additions, so updates to the main house can be considered alongside your ADU. Send us a message describing everything you have in mind, and we will look at how it fits together.
8. How do I request an estimate for an ADU?
Request an estimate through our contact page or just pick up the phone. Tell us about your property and what you want the unit to do, and our team will take it from there with a no pressure conversation about your goals.
