Autonomous|Jan 20, 2023

Whether it's to increase the value of your current home, generate passive income from renting it out, or shelter elderly family members, you're probably ready to add an accessory dwelling unit (ADU) to your Los Angeles property. 

Maybe you're hesitant to start an ADU project because you don't want to disrupt your backyard for a few months. Fortunately, you have the choice to buy a modular ADU in Los Angeles that is already complete and ready to go. 

Prefab ADUs are built offsite at a manufacturer and delivered to your site once they are ready for installation. 

Building this type of unit is typically faster than constructing an ADU from the ground up on your property. 

Prefab ADUs are built based on pre-made blueprints, skipping the architecture and design phases, which can also help minimize costs. 

A prefab ADU in Los Angeles is the best option if you want to add an ADU to your property, but the hassle prevents you from doing so. You'll need to start by choosing a company that can put your ideas into practice and one that provides a high-quality build. Essentially, you'll find the best prefab ADU companies in Los Angeles here, along with the features and services they provide.

Is an ADU Worth the Investment?

Adding prefab ADU units to your property is one of the smartest investments you can make as a homeowner. Your new granny flat will boost the value of your entire house, and if you decide to rent it out to a tenant, you can use that passive income to help with your mortgage payments. 

With a studio, one-bedroom, or two-bedroom home—all of which are exquisitely built to maximize space and functionality, without raising the ADU cost—you can also dramatically expand your square footage. 


What Are the Pros and Cons of an ADU?


The most obvious benefit of buying a home with an accessory dwelling unit kit is the passive income it generates. Depending on its location and the city's rental market, the income will vary. 

Keep in mind that if you're renting it out for a brief period on websites like Airbnb, some of that money will need to go toward any necessary repairs and cleaning costs. 

Furthermore, ADUs can increase the value of your house. Homes with an ADU are approximately 35% more expensive to buy than homes without one, according to Porch. An ADU can be used for visitors or family members even if it isn't being used as a rental unit. 


Ownership of a short-term rental unit includes a variety of costs and responsibilities, which decrease the ADU's passive revenue. 

According to Ben Wagner, a real estate investor and house flipper at Leave the Key in Amityville, New York, "maintenance, repair, and renovations are only the start. Landlords must also account for other costs, such as cleaning fees and insurance coverage." 

Most homeowners' insurance policies can provide protection for extra structures; the cost would usually be in the low hundreds.

Costs for supplies and cleaning will differ. You should set aside $2,500 a year if you plan to rent out a prefab ADU in Los Angeles for short stays. You need to pay to have it cleaned and stocked with essentials like paper goods and hygiene products. 

Operating ADU homes in Los Angeles can have an impact on the homeowner's lifestyle in addition to expenses. Your renter will require access to certain parts of your property, so you want to make sure you feel safe with renters coming and going as they please. 

How Do You Maximize Space in an ADU?

Use vertical space for storage. Install built-in shelves, hidden cubbies, and stacks of drawers straight into and up the walls instead of dressers or huge cabinets, leaving the floor free. 

Create storage lofts above your closets, accessible by a rolling ladder. These adorable nooks can be quickly converted into extra play places for children. 

Add hooks and brackets to your ceiling. Bikes and outdoor equipment are kept out of the way using this method. Consider installing specialized storage platforms that are moved by electronic rails or a pulley system, depending on the nature of the area and how fancy you want to get. 

Don’t forget the precious space under the stairs. Install a sizable storage cabinet or deep built-in shelves underneath any stairs in your ADU, so you can store seasonal items there. 

Use murphy beds. Murphy beds can be set up to save space and entertain any visiting children. During the day, these beds fold up and vanish to make way for daily activities. 

Add a workspace. If your sleeping area is big enough, add a corner desk to function as a nightstand as well as a workspace.


You’ve put a lot of thought, time, and research into adding an ADU to your property. That makes it even more important to pick a business that will support your ideas, allow a smooth process, and deliver excellent outcomes. 

Essentially, you need a turnkey ADU services company that has a staff of attentive, caring professionals and a system for setting up your prefab ADU in Los Angeles quickly and properly. You might even look into backyard office shed kits if you’re a do-it-yourselfer.
