A tip from our CEO
For this 798 sq ft 3-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 798 sq ft 3-bedroom ADU
Explore the layout, customization, budgeting and property considerations for this 798 sq ft plan. Start with the drawing, then check how the design would work at your address.
How many bedrooms and bathrooms does this 798 sq ft plan have?
This layout lists 798 sq ft, 3 bedrooms, 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 798 sq ft 3-bedroom ADU?
The recorded overall dimensions are 44′ × 21′, and the listed area is 798 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 798 sq ft 3-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 798 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 798 sq ft 3-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 798 sq ft 3-bedroom ADU?
The 798 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 798 sq ft 3-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 798 sq ft, 3 bedrooms, 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?
With 3 bedrooms, this plan gives you rooms to compare for sleeping, work or flexible use. Decide how many bedrooms you need to retain, then check furniture, storage and circulation before assigning an office. The 798 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 44′ × 21′ 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 798 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 798 sq ft 3-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 798 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 798 sq ft area, the bedroom and bathroom count, and the recorded dimensions of 44′ × 21′. 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 800 sq ft adu floor plans?
This plan has 798 sq ft, 3 bedrooms and 1 bathroom. The search phrase "800 sq ft adu floor plans" describes a different or rounded size; the listed area for this drawing remains 798 sq ft. Compare the actual dimensions and room arrangement rather than assuming plans in the same size range are identical.
