700 Sq Ft Tiny House Floor Plan: Spacious Living in a Compact Design

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. Sometimes referred to as a “tiny house”, this ADU design just under 700 sq ft is perfect for homeowners who want to add a practical and efficient living space to their property. 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.
  • Site Conditions: While a 700 sq ft ADU can be more affordable and stay in the mid $300Ks all-in, it’s important to note that site conditions such as slope and utility conditions can also have an impact. Check out our site conditions guide to read more.

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:

  • 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.
