Narrow 2 Story ADU Plan: Compact and Versatile Living

Our narrow 2 story ADU plan offers efficient living in a compact footprint under 1,000 sq ft. At just 14 feet wide, this design is perfect for tight spaces while providing all the comforts of a full-sized home. With open living areas downstairs and two bedrooms upstairs, this plan maximizes space for practical and comfortable living.

Smart Layout for Tight Spaces

This two story ADU features a thoughtfully designed layout, perfect for narrow lots. The ground floor includes an open-concept living room, dining area, kitchen, and a convenient half bath. Upstairs, you’ll find two bedrooms, a shared bathroom, and an in-unit laundry area. This arrangement offers privacy, functionality, and plenty of natural light.

Key Layout Features:

• Open Living Areas: The first floor combines the living, dining, and kitchen spaces for a seamless, multifunctional area.
• Convenient Half Bath: A half bath on the main floor adds convenience for guests and everyday living.
• Private Second Floor: Two bedrooms with a shared bathroom provide privacy and comfort, with laundry for added convenience.
• Narrow Footprint: With typical ADU setbacks of 4′ from the property line and 6′ from the main home, you just need 24 feet of room in your yard. Setbacks may vary depending on your city; see your local ADU regulations or reach out to our team.

Benefits of Building a Two Story ADU

Building a two story ADU maximizes vertical space, offering more living area without taking up extra ground space. Many municipalities in Greater San Diego allow two story ADUs. Some cities offer reduced setbacks, making it easier to fit these units into narrow lots. Detached ADUs can typically be 16 to 18 feet tall under state guidelines, but height limits are greater in certain cities.

Why Build a Two Story ADU?

• Maximize Limited Space: Build vertically to gain more square footage while preserving outdoor space.
• Flexible Design Options: Create a layout that adapts to your needs, from family living to rental use.
• Municipal Flexibility: Many cities offer supportive regulations for two-story ADUs, ensuring compliance and practicality.
