Our 700 sq ft accessory dwelling unit (ADU) plans are expertly crafted to provide full functionality while optimizing space in a compact, easy-to-manage design.

Whether you’re planning to build a rental unit or an in-law unit for a family member, this design offers versatility and affordability. The design is ideal for smaller yards at only 17 feet wide, making it versatile for a range of properties. Explore the differences between tiny homes vs. ADUs.

Thoughtfully Designed Layout

This tiny house floor plan just under 700 square feet is designed to maximize every inch of space. The open-concept layout combines the living room and kitchen into a multifunctional area perfect for daily living and entertaining. The kitchen offers plenty of storage with the option to add a peninsula for extra counter space and seating.

Key Design Features:

  • Open Living Room and Kitchen: The open layout creates a spacious feel, while the kitchen’s ample storage and optional peninsula make it highly functional.

  • Primary Bedroom: The generously sized bedroom comfortably fits a queen or king-size bed, with room to spare for additional furniture or storage.

  • Accessible Bathroom: The bathroom is conveniently accessible from both the bedroom and the common area, enhancing privacy and convenience.

  • In-Unit Laundry: A dedicated laundry area ensures that this compact home remains fully self-sufficient.

Compact Size, Big Benefits: Why 700 Sq Ft Works

Although this home is just under 700 square feet, the smart design ensures it feels larger than its actual size. The narrow 17-foot width allows the home to fit perfectly in smaller yards, making it an excellent choice for homeowners with limited outdoor space.

Benefits of the 700 Sq Ft Size:

  • Efficient Footprint: Despite its compact size, the open layout and clever design make the house feel spacious and comfortable.

  • Fits Small Yards: At 17 feet wide, this floor plan fits well on properties with space limitations, while still providing all the amenities of a larger home. For a standard 4 feet setback from property lines (per California state ADU laws) and 6 feet setback from the existing home, you just need 27 feet of backyard space

  • Under 750 sq ft: Jurisdictions can’t charge impact fees (a type of ADU permit fee) when an ADU is under 750 sq ft, making this design a good cost-conscious choice.

Cost to Build a Tiny House

Building a 700 sq ft tiny house offers significant cost benefits compared to larger homes. The smaller size reduces material costs and construction time, making it more affordable to build while still providing ample living space. Additionally, its energy-efficient size helps keep long-term utility costs low.

Key Cost Considerations:

  • Lower Overall Construction Costs: The compact footprint requires fewer materials and less labor, resulting in reduced overall construction costs.

  • Energy Efficiency: A smaller home is easier to heat and cool, leading to savings on utility bills over time.

Best Use Cases for a 700 Sq Ft Tiny House

700 sq ft tiny house plans are ideal for a variety of uses, thanks to its efficient layout and adaptable design. Whether you’re building a rental unit, a guest house, or a private residence for a family member, this compact home offers flexibility and functionality.

Top Use Cases:

  • Rental Unit: The self-contained design is perfect for generating rental income. Tenants will appreciate the modern amenities, including a full kitchen, in-unit laundry, and spacious bedroom. As a one-bedroom, the ideal tenant for this unit would likely be an individual or couple.

  • Guest House: This floor plan is ideal for creating a welcoming space for out-of-town guests. The open layout provides a comfortable common area, while the private bedroom ensures a restful stay.

  • Family Member Residence: A 700 sq ft tiny house is perfect for aging parents or adult children to support multigenerational living, offering them an independent living space while keeping them close to home. Having a little bit more square footage in this plan versus some of our other one bedroom plans, this plan can easily accommodate any accessibility requirements.

A tip from our CEO

MK

For this 663 sq ft 1-bedroom ADU, start by deciding which spaces need privacy and which should connect. Mark the route from the entrance to the living area, then check how it passes the bedrooms and bathrooms. Consider window placement, storage and everyday furniture at the same time so changes to one room do not compromise the rest of the home.

Frequently asked questions about this 663 sq ft 1-bedroom ADU

Explore the layout, customization, budgeting and property considerations for this 663 sq ft plan. Start with the drawing, then check how the design would work at your address.

How many bedrooms and bathrooms does this 663 sq ft plan have?

This layout lists 663 sq ft, 1 bedroom, 1 bathroom and 1 story. Use the drawing to compare the relationship between the sleeping space, bathroom, kitchen and living area.

What are the dimensions of this 663 sq ft 1-bedroom ADU?

The recorded overall dimensions are 39′ × 17′, and the listed area is 663 sq ft. Overall dimensions and floor area describe different things, especially where a building has an irregular outline or more than one level. Use the dimensioned drawing when checking the footprint, and confirm dimensions in the final coordinated drawings before construction.

Is this a pre-approved ADU plan?

The status of this 663 sq ft 1-bedroom ADU is Local Approval Required. The drawing is a starting point for a property-specific design, not an approval for your address. Site placement, utilities, access and the final construction documents still need to be reviewed. An approval held by a reference plan elsewhere does not establish approval for your property.

Can I customize this 663 sq ft floor plan?

Yes, changes can be explored during design. Start with the rooms and features you want to retain, then identify what needs to change. Moving walls, changing windows or rearranging plumbing can affect several parts of the drawing, so review those changes together rather than treating each as an isolated edit.

What should I bring to a 30-minute consultation?

Bring your property address, available site drawings, photos of the existing home and a short list of goals. Tell us why this 663 sq ft 1-bedroom ADU appeals to you and what you would change. Information about access, existing structures and utility locations helps make the conversation more specific, even if you do not yet have a complete set of plans.

How much would it cost to build this 663 sq ft 1-bedroom ADU?

The 663 sq ft area alone is not enough to price construction. Access, ground conditions, utility work, the selected building system and finishes all affect the scope. Request a property-specific estimate that separates design, engineering, permit fees, site preparation and construction. The images on this page do not establish a construction price or a guaranteed total budget.

How long would design, approval and construction take?

The schedule for this 663 sq ft 1-bedroom ADU depends on the property, the extent of customization and the required reviews. Separate the schedule into design, engineering coordination, permit review, site preparation and building work. Ask which decisions or records are needed before each stage begins. A schedule for another property is not a reliable completion promise for yours.

Can this layout work for a family member or multigenerational living?

This layout lists 663 sq ft, 1 bedroom, 1 bathroom and 1 story. Discuss the intended resident’s daily routine before choosing the final arrangement. Check privacy, access to the bathroom, kitchen use and the relationship to the main home. If step-free access or other mobility needs matter, raise them at the start so the entrance, clearances and fixtures can be considered as part of the design.

Can I use part of the home as an office or flex space?

A workspace needs to fit without displacing the essential living and sleeping functions. Consider a desk location, daylight, storage and how the work area can be separated at the end of the day. The 663 sq ft drawing should be reviewed around the actual activities you need the home to support.

Does this plan automatically fit my backyard?

No. The recorded dimensions of 39′ × 17′ are only one part of a fit check. The design team also needs to understand the property boundaries, existing buildings, required access, utilities and applicable development standards. A clear area in a photograph does not establish a buildable envelope. Review the building placement on a measured site plan.

Could this be used for a garage conversion?

This page presents a 663 sq ft floor-plan layout, not a confirmation that an existing garage can accommodate it. A conversion starts with the actual garage dimensions and condition. Structure, floor levels, openings and services need assessment before deciding what can stay. Compare the existing building with this drawing before assuming that the same footprint or room arrangement will transfer.

How should I plan the kitchen, bathroom and laundry?

Review appliance sizes, door swings, storage and the space needed to use fixtures comfortably. Check where water, drainage, electrical and ventilation services would run. Keeping a preferred room arrangement is useful only if the coordinated design can support the way those spaces will be used.

Can the entrance or windows be repositioned?

Entrance and window changes can be explored when adapting this 663 sq ft 1-bedroom ADU. Consider privacy from the main home, the approach from the street, daylight and furniture placement. Moving an opening can also affect the wall and the surrounding design. Review it with the site layout and coordinated drawings rather than relying on the preview image alone.

Will this plan require additional parking?

Parking needs to be checked for the property and proposed ADU type. This 663 sq ft drawing does not establish a parking requirement or an exemption for your address. Include existing parking, driveways and the proposed access route in the site review. Confirm the applicable requirements with the reviewing authority before fixing the building placement.

How can I compare this layout with other ADU floor plans?

Start with the actual 663 sq ft area, the bedroom and bathroom count, and the recorded dimensions of 39′ × 17′. Then compare the kitchen, storage, privacy and access to each room. A larger advertised area does not by itself mean a better fit. Use the floor plan alongside the exterior views, and shortlist the layouts that support your intended use and property.

How does this layout compare with 700 square feet?

This plan has 663 sq ft, 1 bedroom and 1 bathroom. The search phrase "700 square feet" describes a different or rounded size; the listed area for this drawing remains 663 sq ft. Compare the actual dimensions and room arrangement rather than assuming plans in the same size range are identical.
