Benefits of ADU Garage Conversions in Los Angeles

Add Value to Your Property

If you’re looking to sell your property in the future, building an ADU will enhance its value and demand in the property market. The investment you need to develop an ADU is relatively small compared to the value you will drive from the addition.

A property buyer may be attracted to a home with a secondary housing unit because of the prospect of generating income from the ADU.


If you love hosting family and friends, and your home doesn’t have enough space, an ADU is a perfect solution. More importantly, it allows your guests to be near you while maintaining privacy. The secondary living unit also provides extra space for guests to be alone—if need be—during their visit.

Perfect Space for Adult Children and College Graduates

A turbulent economy has forced many ‘young millennials’ to return to their parent’s homes after graduation. The skyrocketing rent prices and job instability doesn’t make it easy for young adults to find a home they can afford.

An ADU is an affordable way to help your kids get on their feet on the ground while living under your roof.

Affordable Development

An ADU uses existing infrastructure such as land, water, energy, and structured parking. As a result, your home gets an additional unit at a fraction of the standard cost.

Ultimate Home Office

An ADU can be a perfect home office if your job allows you to work from home. It can also serve as space for your mental health. Whether you want to meditate or practice yoga, ADU is secluded, creating tranquility and peace.

Construction Process of an ADU

Make Plans

First, we’ll assess your unique needs and wants. Next, our garage conversion contractors will take a closer look at your property and design an ADU plan within your budget and personal taste. For instance, a detached conversion is ideal for generating extra rental income.

When making plans for an ADU, we consider the following;

  • Your budget
  • Available space
  • Timelines for the project
  • Suitability of the ADU to the end user—for instance, a backyard ADU is ideal for an elderly family member.

Acquisition of Permits

We’ll submit the plans in pursuit of approval and permits from the city or state authorities. Submission and approval of permits precede the construction process. As we draft the project timelines, we consider possible delays arising from corrections and adjustments linked with the process.

Site Preparation

We’ll begin the construction phase after getting all the permits we need. Some activities required for site preparation include demolition, clearing, and grading. If need be, we’ll excavate the underground soil before laying the foundation.


Framing involves building walls, roofing, windows, and doors. It also involves setting up joists and exterior detailing.

Setting up ADU Amenities

We’ll set up or install internal amenities like electrical and plumbing connections. We’ll also set up crucial mechanical systems like heating and air conditioning.

Interior Finishing

Once the necessary amenities are set up, we begin interior finishing, which includes insulation, drywall installation, tiling, and installation of light fixtures and kitchen appliances. The last construction phase may consist of adding a driveway, refreshing the landscape, and adding a patio.

Types of Garage Conversions

  • Basement ADU: Basements are heavily underutilized and mainly used as storage or laundry rooms. However, you can remodel it into an accessory dwelling unit. Interestingly, a basement ADU is cooler in summer and offers more privacy than ground-level homes.
  • Detached Conversion: It involves building a separate unit from the primary residential home. A backyard cottage ADU is a perfect example of a detached conversion. Although it requires its own sewer, water, and electrical components, it’s an ideal solution to maintain the privacy of a rental unit.
  • 2nd Floor Conversion: It is typically attached to the primary home, with the most significant consideration being accessibility. It is created like an apartment or townhouse, necessitating a separate entry away from the main living unit.
