Thoughtfully Designed for Narrow Spaces

This narrow ADU floor plan is perfect for properties where space is at a premium. Measuring just over 13 feet wide, this plan optimizes every square inch while still offering a comfortable living space.

Key Features of the Layout:

  • Spacious Bedroom: Despite its compact footprint, the bedroom comfortably fits a queen-size bed and features a walk-in closet for ample storage.

  • Open Living/Kitchen Great Room: The open-concept living and kitchen area is perfect for relaxing or entertaining. The kitchen includes full-size appliances and floor-to-ceiling cabinetry, ensuring plenty of storage and functionality.

  • Full Bath & In-Unit Laundry: The bathroom is accessible from both the bedroom and the common living space, while an in-unit laundry adds convenience without taking up extra room.

  • Under 500 Sq Ft: Reap cost-saving benefits in certain cities for staying under 500 sq ft, such as soils report and wastewater management exemptions. Read more in our ADU size guide.

Benefits of a Narrow Design:

  • Efficient Use of Space: By keeping the design narrow, this ADU makes efficient use of limited square footage without sacrificing key amenities like a full kitchen, bathroom, and laundry.

  • Great for Small Backyards: If your property has a narrow footprint, this ADU can easily fit, offering a flexible living option without needing a large plot of land. With standard 4′ setbacks from property lines and a 6′ setback from the existing home as is the regulation in most cities in Los Angeles, such as Encinitas and Vista, you just need 24′ feet of backyard space for this ADU. This project in Carlsbad built to generate rental income is a great example of using this narrow floor plan in a smaller backyard.

A tip from our CEO

MK

For a compact 497 sq ft home, place your everyday furniture on the drawing before moving walls. Check the bed, a dining place, a comfortable seat and the clear route between the entrance and bathroom. A layout works best when storage and circulation are planned together, rather than added after the rooms are fixed.

Frequently asked questions about this 497 sq ft 1-bedroom ADU

Explore the layout, customization, budgeting and property considerations for this 497 sq ft plan. Start with the drawing, then check how the design would work at your address.

How many bedrooms and bathrooms does this 497 sq ft plan have?

This layout lists 497 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 497 sq ft 1-bedroom ADU?

The recorded overall dimensions are 37′ × 13′, and the listed area is 497 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 497 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 497 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 497 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 497 sq ft 1-bedroom ADU?

The 497 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 497 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 497 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 497 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 37′ × 13′ 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 497 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 497 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 497 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 497 sq ft area, the bedroom and bathroom count, and the recorded dimensions of 37′ × 13′. 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.
