Types of ADUs and Garage Conversions

There are several ways to add living space with ADUs and garage conversions. These options vary by how they are built and connected to your main home. Each has different benefits depending on your property and goals.

Detached ADUs

Detached ADUs are separate buildings on your property. They stand alone from your house and have their own entrances. These units usually range from 400 to 1,200 square feet, depending on local rules. Because they are separate, detached ADUs offer the most privacy for renters or family members.

They often include a kitchen, bathroom, bedroom, and living space. You have more freedom with their design but may face extra costs for separate utilities and permits. Detached ADUs work well if you have enough yard space and want a distinct living area that doesn't share walls with your home.

Attached ADUs

Attached ADUs connect directly to your existing house. They can be built as an addition or as a converted part of the home, like a basement or side room. These units share at least one wall with your house but have their own separate entrance. They often cost less to build compared to detached ADUs because they use existing utilities and structure.

Attached ADUs provide a compromise between privacy and convenience. This option is good if you want to maximize your property's value without losing much outdoor space. It also simplifies access for family members or caregivers.

Garage to ADU Transformations

Converting a garage into an ADU turns existing space into a complete living unit. These conversions include adding a kitchen, bathroom, and sleeping area inside the former garage. This type of ADU is popular because it reuses space without changing your property's footprint. Most garages converted this way range from 300 to 600 square feet.

Garage conversions often cost less than building new structures. But you need to make sure the garage is large enough and meets local zoning rules. Also, walls and insulation may need upgrades to create a comfortable living space. This option works well if you want a quick, cost-effective way to add a rental unit or extra room for family.

Cost and Financing Options for ADUs

Understanding the costs involved and how to finance your ADU or garage conversion is key to planning your project. You need to know what to expect for expenses and the best ways to fund the work without stretching your budget.

Budgeting for Your Project

Typical costs for building an ADU in Commerce, CA, range from $100,000 to $200,000, depending on size and design. Key expenses include design and planning fees, usually between $6,000 and $14,000, and city fees, which can add $3,000 to $11,000. If you convert a garage, costs might be lower since the structure already exists, but you still pay for permits and remodeling.

In a city where the median household income is $48,729 and 16.5% of the population lives below the federal poverty line, we work to develop cost-effective solutions that remain accessible to local homeowners. Other costs to consider are utility hookups, materials, labor, and any upgrades needed to meet current building codes. Setting aside at least 10% for unexpected expenses helps keep your budget realistic.

Financing Solutions

There are different ways you can finance your ADU project. Traditional home equity loans or lines of credit offer flexibility and competitive interest rates. Some banks also provide personal loans tailored to home improvements. Programs like the CalHFA ADU Grant give you up to $40,000 to cover pre-development costs.

You also explore construction loans or work with lenders offering special options for ADU projects. We recommend checking city-specific programs in Commerce for local financing support. Using a mix of savings, loans, and grants can make your project more affordable and easier to manage.



Energy Efficiency and Sustainability

We focus on making your garage conversion or ADU both energy-efficient and environmentally responsible. You save on utility bills while reducing your home's overall impact on the environment.

Eco-Friendly Building Practices

We use materials that are durable and have low environmental impact. This includes recycled wood, low-VOC paints, and sustainable insulation. These choices help keep your indoor air clean and reduce waste.

During construction, we minimize debris and recycle as much as possible. Our team also plans carefully to avoid extra framing or materials. This means less landfill waste and a smaller carbon footprint for your project.

You can expect efficient water use too. We install fixtures designed to reduce water consumption without sacrificing comfort.

Energy-Saving Features

We install high-performance windows and doors to keep your ADU well insulated. This prevents heat loss in winter and keeps the inside cool during summer. Our lighting setup uses LED fixtures that consume less electricity and last longer. We also use smart thermostats and energy-efficient appliances to further cut down utility use.

You can choose solar panel options or other renewable energy add-ons we offer. These investments increase your home's value and reduce your electricity bills over time.
