Factors to Consider When Designing 1-Bedroom ADU Floor Plans

There are many factors that our expert designers consider when designing an ADU. These considerations help ensure that the finished product meets the needs of our clients while also complying with local zoning regulations. We’ll briefly lay out some important factors that you should keep in mind when designing 1-bedroom ADU floor plans:

Size and Shape of the Lot

How large your ADU can be and where it can be located on the property will largely be dependent on the size and shape of your lot. For example, if your lot is narrow, a two-story ADU might be more appropriate than a single-story ADU. It’s important to keep in mind setbacks, easements, and other zoning regulations that could impact the placement and size of the structure.

Local Zoning Regulations

Each municipality has its own regulations for ADUs, so it’s important to research and understand the zoning regulations in your area before starting the design process. Some common regulations include minimum and maximum ADU size, parking requirements, and setbacks from property lines. Understanding these regulations even before starting the project can help avoid costly changes later on.

Budget and Costs

The budget you have for your ADU will be the basis upon which several factors like design and materials to be used will be determined. It’s important to consider all costs associated with the project, such as permits, construction, and landscaping. Be sure to allowances for any unexpected costs that may arise during the construction process.

Purpose of the ADU

The purpose of your ADU will determine its design and layout. For example, if you plan to use your ADU as a rental unit, you may want to design it with a separate entrance and privacy features. If you plan to use your ADU as a guest house, you may want to focus on creating a comfortable and welcoming environment.

Needs and Preferences of the Occupants

The needs and preferences of the occupants of the ADU will also impact the design. For example, if the occupants have mobility issues, you may want to design the ADU with wider doorways and a more accessible bathroom. If the occupants enjoy outdoor living, you may want to incorporate a patio or deck into the design.

Design Tips for 1-Bedroom ADU Floor Plans

Designing 1-bedroom ADU floor plans must be done in such a way that the space is functional, efficient, and comfortable. To help with this, we’ll quickly look at some tips for creating your 1-bedroom ADU floor plan:

Maximize Space and Storage

ADUs are typically small in size, so it’s important to make the most of the available space. Consider using multifunctional furniture, such as a sofa bed or a table that can be used for both dining and work. Use built-in storage solutions, such as shelves and cabinets, to keep the space organized

Create a Sense of Openness

Even in a small space, creating a sense of openness can make the space feel larger and more comfortable. To achieve this, use open shelving, light-colored walls, and natural lighting to create an airy atmosphere. If possible, incorporate windows or skylights to bring in natural light and provide views of the surrounding environment.

Focus on Privacy

Privacy is important in any living space, and it’s especially so in an ADU. You should design the space with a separate entrance, and use sound insulation and solid doors to minimize noise. If the ADU is located close to the main house or other buildings, using privacy screens or landscaping to create a sense of separation will provide the much needed privacy while also adding aesthetic value.

Pay Attention to the Flow of the Space

The layout of the ADU should be designed to maximize efficiency and flow. Picture how occupants will move through the space and design the layout to minimize dead space and maximize functionality. For example, place the bathroom and kitchen close to each other to minimize plumbing costs, and design the bedroom with ample storage and natural light.

Choose Materials Wisely

It’s important to choose durable and low-maintenance materials that can withstand regular use and the elements. Go for materials such as concrete floors, quartz countertops, and hard-wearing cabinetry to create a space that is both functional and beautiful.

When it comes to designing 1-bedroom ADU floor plans, there are several popular styles that homeowners and builders tend to gravitate towards. Each style offers its own unique benefits and considerations. Here are some popular 1-bedroom ADU floor plan styles:

Studio-style ADUs

These ADUs are often ideal for those looking to maximize a smaller lot or to add an additional rental unit to their property. Studio-style ADUs can also be designed to accommodate 2-bedroom ADU floor plans, with the use of additional space or creative design elements.

The main living area is located below the sleeping area and can include a kitchen, living room, and dining area. Loft-style ADUs are an excellent choice for those looking to maximize vertical space or for those who want a more unique living experience. 2-story ADU plans can be incorporated into loft-style ADUs, allowing for additional living space without taking up too much of the lot.

This plan will usually include a bedroom, living room, and kitchen, and may also include a bathroom and laundry facilities. It’s possible for have a variation of this plan that accommodates 2-bedroom ADU floor plans, although additional space may be required to pull it off.

Two-story ADUs

This is one plan that can help maximize the living space without taking up too much of the lot. The plan takes advantage of the vertical space to create more usable living area. It’s common to have a bedroom, living room, kitchen, and bathroom on the first floor, with an additional bedroom or living area located on the second floor. 2 story ADU plans can be incorporated into loft-style or garage conversion ADUs, allowing for additional living space without taking up too much of the lot.

These ADUs can be designed to include a bedroom, living room, kitchen, and bathroom, and can be either single-story or two-story.

Your Property and Surroundings

Your Budget
