ADU Garage Conversion Los Angeles | Gozen Construction


You want to start an ADU garage conversion Los Angeles. It is a great way to add square footage to your home, substantially increase the value of your home, and allow you to generate rental income. Unlike the construction of a new home, adding an ADU falls under the category of a remodel or an addition, not a new construction. This means that, much like any other remodeling project, it will require a building permit and, most likely, some city approvals.

ADU Garage Conversion Los Angeles

ADUs (accessory dwelling units) are a great way to add more living space to your property. And more importantly, they’re a great way to increase your housing options without increasing your property taxes. ADUs are one of the most affordable ways to add a second unit to your property.

ADU garage conversion is one of the easiest ways to add an ADU, and it’s also one of the most popular options for homeowners.

If you’re thinking about adding an ADU garage conversion, it’s important to know what zoning laws apply in your neighborhood and how much you can expect to pay for materials and labor costs.

What is an Accessory Dwelling Unit?

An ADU is also known as a granny flat or in-law unit. It’s a second dwelling unit built on a lot where one already exists. The most common ADUs are detached or attached units, but they can also be internal conversions (basement, attic, or garage) or even additions to your home. An accessory dwelling unit (ADU) is a structure attached to your home, but it’s considered a separate housing unit. It can be used as a rental unit or as an in-law suite.

What You Need To Know About a Garage Conversion

Garage conversions are a great way to make the most of your space and add value to your home. However, they can be tricky to plan and execute. Here are some things you need to know before you start.

The right floor plan – A garage conversion is a new room added to your house. It may share walls with other rooms in the house, but it should also have its own entrance and be separate from the rest of the home.


The right location – Garages are usually located on the ground floor because they’re often used for storing cars and other vehicles, so this makes sense for conversion too. But if you want to make better use of your garage space, consider moving it up into one of the upper floors — this will open up more options for what kind of conversion you can do and how much space it will take up in your home.


The right walls and windows – You need to decide whether or not you want to keep any of your existing walls or windows during a garage conversion — these may interfere with where you want to put doors or windows in your new room, so they need careful consideration before starting work on them.


The right supplies and equipment – Once you know what kind of layout you want, it is time to start organizing materials and equipment so that they are ready during construction. This includes things like paintbrushes, ladders, and other tools that might be required depending on what kind of project you are undertaking. Ensure all tools are cleaned up after each use and stored safely until they are needed again so nothing gets damaged.

Types of Garage Conversion



This conversion involves turning your detached garage into a living space with its own entry from outside the house. Your main residence must be on the same property as the garage conversion. This type of project requires building permits and inspections by city officials.

Attached ADU

If you don’t have enough room for a detached garage conversion, you may consider converting one attached to your house instead. Before you begin construction, this option may require approval from your homeowner association or HOA. The materials used in this type of project will depend on whether or not you want to move walls between the two units or simply convert one into another room within your home.

Internal ADUs

Internal ADUs are attached to your primary residence and share an interior wall. These units typically have their own kitchenette and bathroom but no living room or bedroom space. They’re perfect for adding extra square footage but don’t require any additional permits or fees beyond those required for regular construction projects in California.

Basement conversion ADUs

This garage conversion involves converting the basement underneath your existing house into a new living space. These types of garages often have multiple bedrooms and bathrooms at their disposal. They also tend to be more expensive than other conversions because they require extensive foundation work, waterproofing, and additional insulation and heating/cooling systems. Also, basement conversions can create noise issues if there is insufficient soundproofing between the living space and the rest of the house.

Addition ADUs or “bump-out ADUs”

The addition ADU is one of the most popular types of garage conversion because it has very little impact on your property value and can be done fairly easily. Adding a bedroom or even an entire second story is possible with this type of project since there are no major structural changes required outside of adding new walls inside the existing structure.

Construction & Design

In some cases, you might also need to get special permits and approvals before starting a garage conversion project. Here are some tips on how to plan your garage conversion:


Know if your garage is eligible for conversion: If you have a detached single-car garage, it may be eligible for ADU (accessory dwelling unit) conversion under current zoning laws in many cities. Check with your local planning department for more information about whether your property qualifies for an ADU.


Choose the right location: The best place for your new ADU will depend on where you want it located within your property and what type of structure best suits your needs (e.g., detached or attached). Consider adding an ADU near other living spaces, such as the main house or guest house, so that occupants can interact easily with each other while still maintaining their privacy if desired.

The prefab ADU units come packed with all the modern appliances you will need for your daily life, and they are designed to maximize the space available in your home. The most affordable way to add living space to your home is by adding a prefab ADU, which can range from a small studio to a master two-bedroom suite.

Garage Conversion Plans

The ADU Garage Conversion Plans allow you to take a garage or carport and convert it into an additional living space. This is typically done by adding a second story with stairs and an entrance, but you can also add a basement if you have the room.


If you don’t have any extra land for your new ADU, this is the best way to increase your square footage without expanding your footprint. The plans for garages are similar to other plans on our site, but some special considerations need to be made when converting a garage into an ADU.

Accessory Dwelling Unit Floor Plans 

One of the most popular types of accessory dwelling units is garage conversion. The garage ADU design can use the existing garage space and create a living space above it.


The main advantage of this type of conversion is that there is no need for any structural changes to your property as it uses an existing structure. However, if your garage has an attic space, you must add one to complete the project.

Best Accessory Dwelling Unit

The most common type of ADU is called garage conversion. It involves turning an existing detached garage into an extra room that can be used as an office, playroom, or guest bedroom. The best way to determine if your property qualifies for this conversion is by looking at local ordinances and regulations. Some communities only allow homeowners with single-family homes to add additional units to their property, while others allow all types of residential properties.
