An Accessory Dwelling Unit (ADU) is a brilliant investment to reap higher ROIs while exploring avenues to elevate your life quality and open passive income streams. The city of Los Angeles supports this form of low-cost construction to address the burgeoning rental housing deficit and promote sustainable home improvement models.
Depending on your budget, space, design, and needs, you can construct the ADU as an attached unit or a standalone detached one. Various factors, including the type of ADU, design, space, and location will determine the cost of constructing an ADU.
Read on for a comprehensive overview of cost factors and budgeting tips to build an ADU in Los Angeles.
How Much Does An ADU Cost in Los Angeles?
The median construction cost of an ADU in Los Angeles County is $150,000.
Budgeting is the first step in initiating any given project as it is important to prioritize research so you can ponder over market rates, construction costs, and design elements to regulate your expenses.
You can make this project outrageously expensive with over-the-top luxury enhancements or scale it down to a nominal budget focusing on utilitarian features. Typically, building an ADU in Los Angeles demands a budget of around $100,000 to $400,000, depending on the size, interior layout, and location.
What Is The ADU Cost Per Square Foot In Los Angeles?
The average cost per square foot of building an ADU in Los Angeles is between $300 – $400. Calculating the cost per square foot helps devise an estimated budget to organize your finances and allocate amounts for various aspects of the project.
This cost can vary based on the quality of the raw materials and the location. Space is a crucial factor to consider while determining the cost per square foot. For instance, constructing a 550-square-foot ADU in LA will likely amount to $400 per square foot.
You can make a more accurate estimate by considering the median cost per square foot for building an ADU in your neighborhood. Experts observe that the median cost to build a home in LA can be upwards of $450 per square foot.
It is important to note that many experts advise against relying solely on the cost per square foot because ADUs do not offer the economies of scale advantages commonly associated with constructing a home. An ADU is a much smaller construction project, extensively personalized to your needs and design.
How Much Does A Prefab ADU Cost?
A prefabricated or pre-fab ADU, as it is popularly known, is constructed in a factory and transported to your property for installation. These units come with elaborate living spaces, interior finishing, appliances, fixtures, etc.
The prices for a prefab ADU in Los Angeles start between $80,000 to $160,000, depending on your aesthetic preferences and utility needs. There will also be added costs for shipping, installation, permits, and utility setups.

ADU Cost Factors
Homeowners must consider multiple factors while devising a budget to fund their Los Angeles ADU construction project. An overview of all the potential expenses is important to set priorities and take measures to scale down your project when costs spiral out of hand.
Cost factors will include building site accessibility, size, design, construction expenses, permits, and the type of ADU chosen to build.
Size
The size of the ADU is a crucial metric in determining the overall cost of the project, as size impacts everything, including raw material and labor costs. The more you expand the size of the dwelling, the higher the expense. The average square footage of newly constructed ADUs in California is 615 square feet.
Design
Much like size, design is another vital metric that has a dramatic impact on the cost. The architectural design and interior layout will determine the kind of raw materials and installations required to execute the artistic vision.
Creating a stainless steel kitchen with smart appliances and granite countertops can give your space a larger and cleaner appearance. A modern design will cost significantly higher than for example, a rustic, farmhouse-style kitchen with a small eating area.
Other soft costs will include design plans that will you need to submit to the city for approval. This can include 3D design models, solar designs, and architectural drafting.
Construction Costs
Construction costs can include labor, raw material costs, and utilities. Homeowners will also have to consider the costs of furnishing, interior finishes, and appliances to include within the new unit.
Other expenses include the architect’s fees, structural engineering fees, and other miscellaneous expenses. The contractor generally determines the overall construction cost, depending on the current labor rate and labor availability.
Fees And Permits
Residents in Los Angeles must obtain permits and regulatory permissions from the city building authorities before initiating the ADU construction process. Requirements will be dependent upon the location, interior layout, square footage, and project complexity.
The city authorities evaluate each project individually, and the permit costs, plan check fees, and zoning fees vary based on the project specifications.
Types Of ADUs
Different types of Accessory Dwelling Units will come with different construction costs. The costs of attached, detached ADUs, junior ADUs, and garage conversions vary considerably.
The type of ADU you’re planning to construct will determine the overall cost of undertaking the project. Different interior layouts and structures have distinct cost factors.
Typically, an attached ADU can cost around $100,000 to $250,000, depending on other factors like raw materials and design aesthetics. However, constructing a detached ADU is considerably expensive, requiring $110,000 to $300,000 to finance the project, as it offers tenants more autonomy and privacy.
A garage conversion is the most budget-friendly ADU option, as costs can start between $80,000 to $150,000. Once again, the cost varies depending on your interior layout and square footage.

Minimizing ADU Costs
Homeowners can explore multiple strategies to scale down the project and minimize their expenses. We’ve listed some practical tips to help regulate expenses and prioritize structural elements.
Don’t Splurge on Raw Materials
Most ADU constructions run overboard on the budget because of expensive raw materials. You can find more affordable materials without overlooking crucial aspects like quality, durability, longevity, and aesthetic appeal.
Start with a Pre-Designed Layout
A pre-designed ADU layout is much more affordable than an extensively personalized architectural plan. Customization can cause expenses to add up, while pre-designed layouts are cheaper to execute, and there’s ample room for modifications.
Make Eco-Friendly Installations
Installing solar panels and natural gas will reduce your expenses considerably by eliminating the need for expensive electric and utility systems.
Take the DIY Route Where Possible
If you’re comfortable with some elbow grease and hard work, taking the DIY route can help you save money on small-scale jobs. For instance, you can paint the walls, enhance the landscape, and install cabinets and shelving units.
