About Los Angeles

One of the most sought-after cities in Southern California to live in, Los Angeles is home to a thriving multicultural community, a dynamic arts scene, and endless recreational opportunities. And with its large population that continues to expand, the metropolis faces an increasing demand for affordable housing accessible to all residents.

Many property owners in the city are addressing this need by installing prefabricated accessory dwelling units (ADUs), also known as granny flats, in-law units, or tiny homes. Designed to provide additional living space on a residential property, a prefab ADU in Los Angeles offers a diverse range of customizable finishes and floor plans—from studios to two-bedroom units—to suit any space.

What are the benefits of having an ADU?

A Los Angeles ADU blends functionality with style, offering a versatile and customizable living space that could increase your property value. Property owners can use the structure as a guest house, home office, or dedicated creative studio. Plus, prefab ADUs often incorporate sustainability features, such as green-certified appliances, solar panels, and LED lighting systems, potentially reducing your carbon footprint and utility bills.

And with the city’s skyrocketing housing prices and persistent demand for affordable housing, owning a prefab ADU in Los Angeles can provide a steady stream of rental income. By investing in an ADU, homeowners can maximize their property's potential and tap into the city’s lucrative rental market. The bottom line: Prefab ADUs offer flexibility to adapt to changing needs, whether it's accommodating extended family members or transitioning from a rental unit to personal use.

Los Angeles ADU requirements

With a growing population and limited space, the city of Los Angeles has recognized the need for more accessible and affordable housing options. To meet these demands, the city has set specific requirements for the building process of prefab ADUs.


How much does an ADU unit cost in Los Angeles?

Thanks to the modular nature of these units, property owners can enjoy streamlined offsite manufacturing and assembly, as well as a shorter ADU project timeline compared to traditional on-site builds. As a result, buying a prefab ADU in Los Angeles could cost anywhere from $184,000 for a standard 400-square-foot studio to upwards of $450,000 for a premium 1,200-square-foot unit designed as a single-family home. These estimates cover expenses for materials, labor, and local government fees.

Building Permits

How do I get an ADU permit in Los Angeles?

The permitting process for ADU construction begins with checking local zoning ordinances and property information. Then, the ADU builder must provide information for the Los Angeles Department of Building and Safety (LADBS) to evaluate, which include a plot plan, energy conservation details, and a foundation plan. The LADBS will assess the submitted documents and issue a permit upon plan approval.


What are the top ADU requirements in Los Angeles?

A prefab ADU in Los Angeles must follow the city’s residential, zoning, and building codes. This includes having a sewer connection either in front of the primary property or downstream of the main structure. Gas lines need valves that can shut off at ADU entrances and supply connection areas. Likewise, protected water lines must also have shutoff valves.


How do I finance an ADU unit in Los Angeles?

To finance an ADU, property owners can take out a home equity loan or line of credit, apply for a construction loan, or look into cash-out refinancing. In addition, certain homeowners may qualify for special financing options like grants. For instance, the CalHFA ADU Grant Program gives home builders up to $40,000 for ADU pre-development expenses, including costs associated with building permits, property surveys, and site prep.

FAQs: Prefab ADUs in Los Angeles

The LADBS considers the ADU project's size and scope, such as the complete cost of construction, to calculate building permit fees. For example, take a homeowner who wants to build an ADU spanning 1,200 square feet. If the prefab home is a new single-story detached unit worth $121,200 in labor and materials, the permit fees could amount to roughly $8,450.

Start with the LADBS’s list of vetted ADU companies providing pre-approved units that meet the city’s building codes. Next, visit open houses and attend local real estate events. This allows you to explore properties firsthand and connect with agents who can guide you accordingly. These professionals may have access to extensive databases featuring properties that meet your criteria, including those with ADUs featuring porches or sliding glass doors.

It’s mandatory for Los Angeles ADUs to have a living area, as well as sanitation facilities and dedicated spaces for cooking, eating, and sleeping. Common appliances that comply with these requirements include energy-efficient refrigerators, ovens, cooktops, water heaters, and dishwashers. For convenience and comfort, prefab ADUs may also come with air conditioning, heating systems, and built-in washing and drying machines.
