Given the high cost of real estate and land in Los Angeles, homeowners are constantly looking for ways to maximize their property’s potential. For those in need of extra living space, quarters for an aging parent, a private home office or a steady stream of rental income - to name a few - one solution stands above the rest: the accessory dwelling unit (ADU).

So the common question is: What are ADUs and how can I add one in LA?

Navigating the terminology and the city’s complex permitting process can feel like a tall order. At South Land Remodeling, we’re an experienced ADU builder who can turn these ambitious ideas into beautiful, permit-ready realities.

What is an ADU?

An accessory dwelling unit (ADU) - often also called a granny flat, guest house, pool house or backyard cottage - is a secondary residential unit located on the same lot as the primary home. Unlike a simple room/home addition, an ADU is a self-sufficient living space equipped with its own kitchen, bathroom and entrance.

There are three primary types of ADUs you can build in Los Angeles:

Detached ADU: A standalone structure in your backyard.
Attached ADU: An addition that shares at least one wall with your main house.
Junior ADU: Attached to the house and shares utilities, so it typically costs less to construct. Plus, in this case, since it takes up less of your property, you can still build an additional detached ADU as well.
Garage Conversion: A garage conversion transforms your garage’s foundation into a one- or multi-story ADU. This can be permitted as an ADU or junior ADU.

Why an ADU is a Smart Investment

In a high-demand market like Los Angeles, an ADU is one of the most strategic moves a homeowner can make. It immediately increases your property’s resale value and offers unparalleled flexibility. Plus, with rising rental rates in LA, a backyard unit can practically pay for itself over time, providing a reliable monthly "mortgage helper."

How to Add an ADU to Your LA Home

The journey from "concept to keys" involves several critical phases, all of which South Land Remodeling can guide you through:

Feasibility Study: Checking your lot size, setbacks and zoning requirements.
Design & Architecture: Creating a design and blueprints that maximize small-footprint living.
Permitting: This is often the most daunting step. In Los Angeles, you must navigate approvals from the Department of Building and Safety (LADBS) and ensure compliance with state laws, which has streamlined the approval timeline.
Construction: Starting with breaking ground on the foundation, framing and utility hookups, and ending with final inspections.
