Testimonials

  • Sarah L.

    Toiling Builders Inc did a fantastic job on our detached ADU. Peri was our project manager and handled everything so smoothly from permits to final inspections. The new guest house looks incredible, and the quality is top-notch. Thank you, Peri, for making this such an easy experience.

  • David M.

    I can’t believe how Toiling Builders transformed my old garage into a beautiful ADU. Michael managed the project and kept me updated every step of the way. The workmanship is excellent, and the whole process was faster than I expected. Highly recommend them for garage conversions!

  • Anna R.

    Peri and Michael helped us build a brand-new ADU from scratch, and we couldn’t be happier. They were attentive, professional, and worked with us to create a design that fit perfectly on our lot. The space is already rented out, and it’s generating income. Toiling Builders Inc really knows what they’re doing.

  • James K.

    We wanted to maximize our property, so Toiling Builders built us a two-story ADU. Peri was our main contact, and she did an outstanding job managing the process. Everything came out better than we imagined the design, finishes, and layout are perfect for our family.

  • Jonathan S.

    I hired Toiling Builders Inc to convert my garage into a rental unit. Peri was in charge of the project and made the whole process seamless. She took care of permits, inspections, and design recommendations. The finished ADU looks amazing and is already rented out. Couldn’t be happier with the results.

Why Build an ADU in California (2025)

⏱️Fast, ministerial approvals

Cities must approve or deny a complete ADU application within 60 days. No discretionary hearings.

🏡Boost Your Home Value

Adding an ADU can significantly increase your property’s resale value. In California’s housing market, a well-designed ADU makes your home more attractive to buyers and appraisers, often adding hundreds of thousands in value.

🏘️Rental & Income Opportunities

Whether you rent your ADU long-term, short-term, or keep it flexible for family use, it becomes a powerful source of extra income. Many homeowners use ADUs to offset mortgage payments, build financial security, or even create ongoing passive income.

✔️Pre-approved plans

Cities are required to offer programs for pre-approved ADU plans (rolling out 2025), which can speed permitting.

👨‍👩‍👧‍👦Adaptable Space for Life’s Changes

Beyond the financial benefits, ADUs provide freedom and flexibility. They can serve as a private guest house, workspace, or multigenerational living space—adapting as your needs change.

📈Potential resale flexibility

Under AB 1033, cities may allow ADUs to be sold separately as condos (some already do, like San José); availability varies by city.

FAQs

  • An Accessory Dwelling Unit (ADU) is a secondary housing unit built on the same lot as your primary home. It can be a detached unit in your backyard, a garage conversion, or even an addition attached to your house. Each ADU is designed with its own entrance, kitchen, bathroom, and living space, making it a fully independent residence. ADUs are ideal for housing family members, creating rental income, or simply expanding your living space without having to buy new property.

  • We specialize in every type of ADU allowed by California law, including:

    • Detached ADUs (stand-alone structures, often called “backyard cottages”)

    • Garage Conversions (transforming an existing garage into a livable unit)

    • Attached ADUs (built as an addition to your main home)

    • Basement Conversions (turning unused space into a functional unit)

    • Junior ADUs (JADUs) (smaller units created within the existing footprint of your home)
      Our team helps determine which option works best for your property, budget, and long-term goals.

  • Rental income depends on size, design, and neighborhood, but in the Los Angeles market, most ADUs rent for $2,200–$3,500 per month. A well-located, well-designed ADU can pay for itself over time and generate consistent passive income. Our team can provide rental comps for your area so you have a realistic idea of the income potential before you build.

  • On average, the full process of designing, permitting, and building an ADU takes about 6 to 9 months. The first few months are usually dedicated to feasibility studies, design, and securing permits from the city. Construction itself typically takes 3 to 5 months, depending on the size and complexity of the unit. While some projects may take longer due to city delays or unique site challenges, we pride ourselves on keeping clients updated every step of the way and ensuring timelines stay as predictable as possible.

  • Costs vary widely depending on the type of ADU, square footage, finishes, and site conditions. A garage conversion may cost significantly less than building a detached two-bedroom unit from the ground up. After we conduct a feasibility assessment, we provide a detailed estimate tailored to your property and goals. While it is an investment, building an ADU is often far more cost-effective than purchasing a new property, and it provides both rental income opportunities and long-term property value increases.

  • Yes, every ADU requires city permits. The good news is that California has passed laws that make ADU approvals faster and easier than ever. At Toiling Builders Inc, we handle the entire permitting process for you: from preparing architectural drawings and submitting applications to responding to city comments and securing approvals. Our experience working with Los Angeles building departments means fewer delays and smoother approvals.

  • Absolutely. Adding a legal ADU can significantly increase your property’s resale value—often by 30–40% or more, depending on the size and rental potential of the unit. Buyers love properties with ADUs because they offer built-in income potential or multigenerational living options. Even if you don’t plan to rent out your ADU, it can still enhance your home’s functionality and overall appeal in today’s housing market.


  • We’ve created a clear, step-by-step process to keep your project stress-free:

    1. Feasibility & Site Review – We analyze your property for setbacks, utility connections, zoning requirements, and potential designs.

    2. Design Phase – Our team drafts floor plans, elevations, and finish options, tailoring the design to your needs and lifestyle.

    3. Permitting – We prepare applications, manage communication with the city, and secure permits on your behalf.

    4. Construction – Our licensed team handles every aspect of the build, from foundation to finishes, with regular inspections and quality checks.

    5. Handover – Once construction is complete, we finalize inspections, obtain your certificate of occupancy, and hand over a fully move-in ready ADU.

    Throughout every stage, your dedicated project manager (Peri or Michael) will guide you, answer your questions, and ensure that the project stays on time and within budget.
