2-bedroom ADU floor plans

Measuring just 25’x20’ feet, this square-shaped, 500-square-foot floor plan has ample space for all the comforts of larger homes, including in-unit laundry! Each bedroom offers complete privacy, as well as storage, and the open-concept living space has room for a small dining table for guests. The bathroom, just off the main space, is a full bathroom, not a ¾ bath, with a combination tub & tiled shower.

By lengthening the ADU's floor plan slightly and increasing the total square footage to just over 600 square feet, you can see that this floor plan offers the feel of more traditional homes, with both bedrooms located in the back of the unit, offering more privacy from the living area. It also includes a private patio space with an outdoor laundry unit, perfect for Southern California.

This ADU design has approximately the same square footage as the last but is longer and narrower in footprint, allowing two truly separated bedrooms, one located on each end of the unit. The bathroom is placed next to one of the two bedrooms, which gives that bedroom the feel of a true master suite. We see this design most commonly used by clients who are looking to give aging parents an in-law suite that still offers guest accommodations in the form of an extra bedroom. Other clients built this design of ADU to use the second bedroom as a cozy home office while offering the master suite to guests when they come to visit.

For homeowners with a bit more lot space and construction budget, this ADU floor plan offers 2 full bedrooms and 2 full bathrooms. One of these bathrooms is attached to the bedroom, making it a true master retreat. The open living area also provides ample living space and dining space, with room for a full-sized dining room. The kitchen also offers plenty of counter space, as the counters extend the full length of the wall. This is a great layout for maximizing rental income, as it provides the feel of a true single-family home right in your backyard space.

This thoughtfully designed 800 sq. ft. ADU offers a perfect balance of comfort and functionality, making it an excellent choice for individuals seeking a well-proportioned 2-bedroom, 2-bath layout. With two master bathrooms, this floor plan is ideal for accommodating multiple renters or aging parents, ensuring privacy and convenience for each resident. Whether used for extended family, rental income, or a comfortable downsized lifestyle, this ADU maximizes both space and livability.

This floor plan is one of our largest custom ADU floor plans when it comes to 2-bedroom projects. Like the last example, the 2 bathrooms are connected to the 2 bedrooms, providing 2 true master suites. However, the bathrooms in this model are a bit smaller than the last, and the extra space is given to the closets in either room and the private terrace space off the side of the unit. This layout is ideal for multigenerational living with elderly parents or adult children, as it provides the feel of 2 single-family homes on the same property.

A good 2-bedroom ADU has private bedrooms, open living spaces, lots of natural light, and smart storage. You can also add extras like a second bathroom or a patio to make it more functional.

Use an open floor plan, big windows, and light colors to make it feel roomy. Built-in storage and multi-use furniture, like a kitchen island with seating, can help maximize space.

Popular layouts include L-shaped designs for corner lots, rectangular plans for narrow spaces, or even two-story options if you’re short on land but need more room.

Absolutely. They’re great for renting to small families or roommates, and they also work well for multigenerational living, giving everyone their own space.

They usually range from 600 to 1,200 square feet. Smaller ones work well for tight lots, while larger ones can include extra features like a second bathroom or bigger kitchen.

Think about how you’ll use it—rental, family, or guests. Focus on natural light, privacy between bedrooms, and features that fit your lifestyle, like extra storage or outdoor access.

It depends on your lot size and goals. Open layouts work well for small spaces, while larger lots can fit more customized designs like two bathrooms or extra living areas.

1-bedroom ADU floor plans are perfect for singles or couples, offering compact layouts like studio ADU floor plans, often starting at 400–500 sq. ft. In contrast, 2-bedroom ADU floor plans provide more flexibility, accommodating small families or roommates with sizes ranging from 750 sq. ft. to 1,200 sq. ft. For even larger families, 3-bedroom ADUs or even 4-bedroom floor plans are ideal, often designed as 2-story ADUs or layouts above a garage to save space on smaller lots.

Yes, garage conversions are a popular choice for 2-bedroom ADUs. You can choose from narrow ADU plans to maximize a small footprint, or expand the garage to create a 750–1,000 sq. ft. unit. Floor plans to convert a 2-car garage into living space often feature an open-concept kitchen and living room, with bedrooms on opposite sides for privacy. For more room, consider ADU garage conversion plans with an additional floor above the garage.

For smaller lots, ADU floor plans of 500–750 sq. ft. offer smart layouts like granny flat floor plans or narrow designs that fit tight spaces. Mid-sized 2-bedroom plans, around 1,000 sq. ft., allow for extras like a second bathroom or a dedicated laundry room. Larger ADU floor plans, up to 1,200 sq. ft., can include 2-story ADU designs or features like an ADU above the garage, maximizing vertical space. Whether you’re working with small ADU floor plans or larger ones, each can be tailored to your needs.
