About Service

ADU Builders You Can Trust to Get It Done

California has made ADU construction easier than ever through updated state legislation, reduced permit fees, and streamlined approval processes. Despite this, many homeowners still find the process overwhelming. Navigating local building departments, coordinating design and engineering, and managing a construction project of this scale requires experience.

Wise Choice Remodeling has built ADUs across the greater Los Angeles area. We know what local building departments require, we understand the California ADU laws that govern setbacks, height limits, and unit size, and we manage the full construction process with our own crew from the first permit application through the final inspection.

Whether you are building for rental income, housing a family member, or adding long-term value to your property, we build it right.

Full Permit Coordination

We handle the full permit process including plan submission, corrections, and scheduling inspections throughout construction.

In-House Construction

Our crew handles framing, mechanical, insulation, drywall, and all finish work. One team from foundation to final inspection.

Reasons to Build an ADU

Generate Rental Income

An ADU on your property can generate significant monthly rental income in Southern California’s housing market. Many homeowners offset their mortgage costs substantially with ADU rental revenue.

House Family Members

ADUs are commonly used to provide independent living space for aging parents, adult children, or other family members while maintaining proximity and connection.

Increase Property Value

A permitted, properly constructed ADU adds measurable value to your property and makes it more attractive to future buyers.

Create a Home Office or Studio

A detached ADU provides fully separate workspace that eliminates the compromise of working from inside the main home.

You Have the Space and Want to Use It

Many Southern California lots have underutilized space in the backyard, above a garage, or in an attached structure that could be converted to a fully permitted living unit.

Key Benefits

Why an ADU Is One of the Best Investments in Southern California

In one of the most expensive housing markets in the country, an ADU gives you rental income potential, housing flexibility, and property value appreciation in a single project.

Rental Income Potential

Southern California rental rates make ADUs one of the highest-returning property improvements available. Many homeowners recoup their construction cost in rental income within a few years.

Significant Property Value Increase

A permitted ADU adds appraised value to your property. Buyers increasingly seek properties with existing ADUs or ADU potential.

Multigenerational Living

An ADU allows family members to live independently on the same property, a housing solution that is increasingly practical and in demand.

California ADU Laws Work in Your Favor

Recent California legislation has significantly reduced ADU permitting barriers, lowered fees, and streamlined approvals. Now is a favorable time to build.

Our Process

Our ADU Construction Process

ADU projects involve more coordination than most residential construction. Our structured process keeps everything on track from first consultation through final inspection.

Site Assessment and Feasibility

We assess your property, review local zoning and ADU regulations, and determine what type and size of ADU your lot can support. We give you a clear picture of what is possible before any money changes hands.

02

Design and Permit Submission

We coordinate with designers or architects to prepare permit-ready plans and submit to your local building department. We manage the review process and address any corrections.

03

Site Preparation and Foundation

We prepare the site, handle any grading or drainage requirements, and construct the foundation appropriate for your ADU type.

04

Framing and Mechanical

Our crew frames the structure and installs rough plumbing, electrical, and HVAC. All work is inspected at the required stages.

Our ADU Construction Services

Detached ADU Construction

A new freestanding structure built in the backyard of your property. Detached ADUs offer the most privacy and flexibility for both the primary residence and the ADU occupant.

Attached ADU Construction

An ADU built as an addition to the existing home, sharing one or more walls with the primary residence. Typically less expensive than a fully detached unit.

Garage Conversion ADU

Converting an existing attached or detached garage into a permitted living unit. One of the most cost-effective ADU options where the existing structure is suitable.

Junior ADU (JADU)

A smaller unit created within the existing footprint of the primary residence, typically from a bedroom or attached garage. JADUs have streamlined permitting under California law.
