Accessory Dwelling Unit (ADU) Services in Pacific Palisades

Garage conversion ADU

We convert an existing garage into a livable unit, working within the footprint that’s already there. Building within an existing structure keeps the project simpler and generally faster than new construction from the ground up.

Detached ADU construction

For lots with enough usable yard space, a detached accessory dwelling unit gives you a fully separate structure built new. We design it around the specific slope, access, and sightlines of your property, since a standard plan rarely works as-is on a Pacific Palisades hillside lot.

Hillside and sloped lot builds

A sloped lot needs different foundation, drainage, and access planning than a flat one. We walk each property individually and assess the grade before recommending a build approach.

What You Can Use an Accessory Dwelling Unit For

Rental income

A separate unit with its own entrance, kitchen, and bathroom can be rented independently of the main house. We design the layout and access with tenant privacy in mind.

Multigenerational housing

An ADU gives a parent, adult child, or relative their own space on your property. We can build in single-level access and wider doorways where that matters.

Home office or studio

A detached unit separates work from the main house. We plan electrical capacity and insulation around how you’ll actually use the space.

Guest accommodation

A finished, fully independent unit handles long-term guests without giving up a bedroom in the main house.

Sierra Construction's ADU Program and Custom Plans

Our approach centers around your unique vision and needs. As a family business led by a dedicated husband-and-wife team, we bring personal attention to every project we undertake. Our comprehensive Accessory Dwelling Unit Services start with understanding exactly how you plan to use your new space.

We offer several pre-designed layouts that can be customized to your preferences, or we can create a completely custom plan from scratch. Each project receives the same careful planning and quality craftsmanship that has become our trademark. We work within your budget while never compromising on materials or construction quality.

What's Included in Your Accessory Dwelling Unit Build

We build each accessory dwelling unit as a complete, independent living space with everything a separate residence requires.

Kitchen and bathroom: Full kitchen and bathroom, plumbed and connected as part of the build.

Utility connections: Electrical, plumbing, and HVAC connections run to the unit, including any panel work the main house needs to support it.

Independent entry: A separate entrance so the unit functions on its own, without routing through the main house.

Finishes. We install flooring, cabinetry, fixtures, and finishes to the level you select during design.

Frequently Asked Questions About Accessory Dwelling Units in Pacific Palisades

What does an accessory dwelling unit cost in Pacific Palisades?

Cost depends on whether you’re converting a garage or building detached, the finished size, your lot conditions, and the finish level you choose. Hillside and sloped lots typically cost more to build on than flat ones. We give you real numbers after an on-site visit.

Does adding an accessory dwelling unit increase my home's value?

An ADU adds finished, independent living space to your property, which is generally reflected in what the property is worth. How much depends on the unit’s size, finish level, and your local market. Talk to a local appraiser or agent for a figure specific to your home.

What's the difference between a detached ADU and a garage conversion?

A garage conversion turns your existing garage into a livable unit within the structure that’s already there. A detached ADU is a separate building constructed new on your lot. Garage conversions are generally faster and more affordable; detached units give you more design freedom and a fully independent structure.

Is there a $40,000 ADU grant available in California?

California has run accessory dwelling unit grant programs through CalHFA, though funding availability and program status change over time. Check CalHFA’s current program page directly for what’s available and whether you qualify. We can build your ADU regardless of how you finance it.

How long does it take to build an accessory dwelling unit?

Timelines vary with lot conditions and unit type. Garage conversions generally move faster than detached new construction, since the structure already exists. We give you a schedule specific to your property at estimate.

Can I build an ADU on my property?

Most single-family Pacific Palisades lots can accommodate an accessory dwelling unit, but slope, access, and available yard space all affect what’s possible. We walk your property and tell you honestly what fits before you spend anything.
