More about us

ADA-Compliant ADU Construction Service

Our Approach to Accessibility

We start by assessing your site and needs to ensure the ADU is easy to navigate for everyone. Features like wider doorways, ramps, and grab bars are included where needed.


We follow ADA guidelines strictly. This means accessible bathrooms, kitchens, and pathways that meet all legal requirements. We use materials and layouts designed for comfort and ease of use.


Our goal is to create spaces where all residents and visitors feel safe and independent. We prioritize details that improve access without sacrificing style or function.

Personalized ADU Design Services

We work closely with you to design an ADU that fits your lifestyle and accessibility needs. You get to choose layouts, finishes, and smart design elements that match both ADA standards and your preferences.



Our team considers natural lighting, easy-to-reach storage, and open floor plans. These choices make the ADU practical and pleasant to live in.

We provide 3D models and clear plans so you understand every step. This way, you have control over all design decisions before construction begins.

Project Management and Quality Assurance

We manage every part of your ADU project from start to finish. This includes permits, inspections, and ensuring contractors follow ADA rules properly. Our team schedules regular updates and site visits.


We make sure work stops only when everything meets quality and access standards.

Before finishing, we test all accessibility features. This guarantees the ADU is fully functional and safe for you and your guests.

Modern ADU Builder’s Commitment to Inclusive Housing

At Modern ADU Builder, we focus on creating ADUs that meet the needs of all users. We design and build ADA-compliant units to ensure accessibility for everyone, including seniors and people with disabilities. Our team understands the importance of universal design. We use features such as:


  • Wider doorways and hallways
  • Zero-step entries
  • Accessible kitchens and bathrooms


These elements make it easier for you and your family members to move around safely and comfortably. We also work closely with you to tailor each ADU to your specific needs. Whether you need handles instead of knobs, or lever-style faucets, we adjust the design to fit your lifestyle.


Our process is transparent. We keep you informed at every step and follow the latest ADA standards. This way, you get a unit that is safe, functional, and welcoming.

Factors Influencing Project Cost

The cost of your ADA-compliant ADU depends mostly on materials, labor, and design features. About 50-60% of the budget goes to construction materials like lumber, fixtures, and finishes that meet ADA standards. Labor costs usually make up 30-40%, reflecting the skilled work needed for accessibility features.


Customizing your ADU with ramps, wider doorways, and accessible bathrooms can add to the price. Site preparation, permits, and inspections also affect costs. Each project is unique, so we assess your site and needs to give you an accurate estimate.

Available Financing Solutions

We know financing a project like this can be a concern. Many homeowners use home equity loans or lines of credit, which often offer lower interest rates because they’re tied to your property.


Some companies, including ours, may offer low down payment options. For example, certain ADU contractors accept as little as $1,500 down to start. Other options include personal loans or specialized construction loans designed for building secondary units.



We guide you through financing choices based on your credit and budget, helping you find the most manageable way to fund your ADA-compliant ADU.

FAQs on ADA-Compliant ADU Construction

Hi there! Have some questions about our service? Find the answers below. 

  • What are the ADA compliance requirements for constructing an ADU in California?

    In California, ADUs intended for private residential use are not typically required to comply with ADA standards unless they're being built for public accommodation purposes. However, California does have accessibility requirements under the California Building Code (CBC) Chapter 11A for covered multifamily dwellings. Key considerations include providing at least one accessible entrance on an accessible route, accessible paths of travel, doorways with minimum 32" clear width, switches and controls at accessible heights, and reinforced bathroom walls for potential grab bar installation. Local jurisdictions might have additional requirements or adaptability standards that exceed state minimums.

  • How does Modern ADU Builder address ADA-compliance in the planning and construction phases of an ADU?

    During planning, we review your site and discuss accessibility needs to create a detailed, compliant design. We include all ADA features required by law.


    In construction, we follow the plans strictly and use quality materials that support accessibility. We inspect key elements like door widths and bathroom fittings to confirm they meet ADA standards.

  • I can’t find my original receipt. What should I do?

    If you can't find your original receipt, contact the company's customer service team with your order information, purchase date, and payment method. Many businesses can look up transactions in their systems using your name, email address, or credit card information. For online purchases, check your email for digital receipts or log into your account on the retailer's website to access purchase history. If you paid by credit card, your statement might serve as proof of purchase for warranty or return purposes.RetryClaude can make mistakes. Please double-check responses.
