Square Design for Optimal Layout and Space

The square design of this ADU maximizes the use of space, offering excellent flow between rooms. This simple yet effective layout ensures that no square footage is wasted, making the unit feel more spacious than its 750 square feet might suggest. Vaulting the ceilings is another option that can make the space feel even bigger and more open, creating a comfortable living environment that feels larger than it is.

Perfect for Roommates or Small Families

With two equal-sized bedrooms, this floor plan is ideal for roommates, offering balanced space and privacy. The shared bathroom is easily accessible, and additional French doors and sliding glass doors (as shown in the photos) can further enhance the unit’s natural light and indoor-outdoor connection.

Why Choose Just Under 750 Sq Ft for Your ADU?

Opting for ADU floor plans under 750 sq ft comes with several strategic benefits, both in terms of cost savings and functionality. California state law exempts ADUs under 750 square feet from paying impact fees, which can result in significant savings on your build. Additionally, a 750 square foot ADU provides ample space for comfortable living, making it a great choice for those looking to build a two-bedroom unit.

Save on Impact Fees

One of the biggest advantages of keeping your ADU size below 750 square feet is the exemption from impact fees in California. Impact fees are charges that cities or counties impose on new construction projects to offset the potential burden on public infrastructure like roads, parks, and schools. These fees can add up quickly, often totaling thousands of dollars depending on your location. Read more about ADU fees.

By choosing a plan that is just under 750 square feet, you can avoid these extra costs, making your project more affordable without sacrificing the functionality of the space. For homeowners looking to build an ADU as a rental unit or as an extension of their living space, this can be a game-changer, making the overall cost of adding an ADU much more manageable.

Comfortable Living Space for Two Bedrooms

Even at 750 square feet, it’s possible to design a two-bedroom ADU that doesn’t feel cramped. With smart planning, a 750 sq ft ADU can provide two equal-sized bedrooms that are perfect for various living situations, including small families, roommates, or guests. The two-bedroom layout allows for a shared bathroom that is easily accessible from both bedrooms and common areas. This makes the unit functional without feeling congested, offering a balanced space where each occupant can enjoy their own private area. Choosing 750 sq ft ADU plans not only keeps your costs lower by avoiding impact fees but also offers a space-efficient and comfortable living solution for various needs. With the right design, it’s possible to create a welcoming, functional space that feels just right.

Is a Pre-Approved Plan Right for You?

Pre-approved ADU plans offer several advantages:

• Faster Permitting: These plans meet local codes and are pre-reviewed, cutting down on approval times.
• Lower Costs: Skip custom design fees with pre-designed layouts tailored to local requirements.
• Simplified Process: Pre-approved plans estimate much of the uncertainty in the design and permitting stages.

They are a great option for homeowners who want to fast-track the design & permitting process and reduce costs. However, it is important to note that pre-approved plans cannot be customized. They are fixed designs intended to simplify and expedite the process, but they do not allow for adjustments such as reconfiguring rooms, resizing, or adding custom features.

If you’re looking for more flexibility, this layout can be tailored as a semi-custom ADU plan. Read more about customization paths in our Custom ADU Guide.
