1 Bedroom ADU floor plans are available in different styles and layouts created on any space between 400 to 600 sq ft in either I, L, or custom-shaped layouts. These ADUs, short for Accessory Dwelling Units, are built alongside the main residential property to provide a comfortable and flexible unit that can function as a guest house, elderly housing, or rental space. Amongst various floor plans, the 1 bedroom ADU plan is deemed one of the most efficient and practical options for various reasons. 

With RenoFi’s financing options, you can fund a 1 bedroom ADU which will boost the value of your property and maximize comfort for every visitor and tenant. Keep reading to learn everything you need to know when building a 1 bedroom ADU floor plan that aligns with your needs and preferences. 

Basics of 1-Bedroom ADU Floor Plan

A 1 Bedroom ADU, also referred to as a granny flat, is a self-contained living space that is tailored to maximize functionality and comfort in a limited area. They are built on the same lot as the single or multi-family home and consist of a single bedroom, kitchen, bathroom, and living area. 

The main advantage of a 1 bedroom ADU layout is that it offers just the right amount of privacy and space desired by an individual or newlyweds. Its compact and complete structure makes it a valuable addition to generating rental income from or to house elderly parents, grandparents, and even grown-up children. 

The floor plan for any 1BR ADU can be developed to integrate with the existing space or to cater special needs of the occupants. 

RenoFi is the smartest way to finance your ADU project. ADUs not only increase your home’s value but can also generate rental income. However, ADUs are costly. If you don’t have enough equity in your current home, funding an ADU construction with a home equity loan is impossible.

For example, let’s say your current home value is $500,000, and your outstanding mortgage balance is $400,000. You are planning on adding an ADU and expect the value of your home to increase to $640,000. Your current loan-to-value ratio (LTV) is already at 80%, which means that most home equity loans are out of reach because that’s the maximum LTV they allow. So, your borrowing power using your current equity is essentially $0.

RenoFi, on the other hand, would allow you to go as high as 150% LTV of your current value or 90% of your after renovation value, whichever is lower. So, in this example, while using a standard home equity loan results in your borrowing power being $0, a RenoFi loan allows you to borrow up to $176,000 by using the after renovation value of your home!

A 1 Bedroom ADU floor plan is an exceptional strategy to optimize available space in your backyard and transform it into a welcoming residential unit for frequent visitors and family members. Here are the most popular 1 bedroom ADU floor styles that elevate the style and convenience of the property with their unique features:

Single Story ADU

A single-story ADU is the most suitable style of 1 BR floor plan due to its simple and straightforward design. It contains a bedroom, kitchen, living room, and laundry area. This style can also be upgraded to facilitate two bedrooms if sufficient space is provided.

Two Story ADU

In contrast to a single-story, a two-story ADU offers additional living areas by making use of the vertical space. In this floor plan, a bedroom, kitchen, bathroom, and living room are situated on the first level, while the second floor contains an additional bedroom or living room. This is an ideal style to enlarge the space you have without taking up too much space.

Studio Style ADU

A studio-style ADU is built around the concept of open living spaces and combines a bedroom, kitchen, and living room in just a single room. This option is ideal for generating rental income from smaller lots and, with some additional space, can also accommodate two bedrooms for maximized space.

Loft Style ADU

Loft-style ADUs, just like 2-story ADUs, are built to take advantage of the vertical space. In this layout, the bedroom is a raised sleeping platform that can be reached by a ladder or staircase. The living room, kitchen, and dining area are located beneath the sleeping area, offering a distinctive living experience.

Apart from these styles, you could also try transforming a garage space into an ADU with the use of design elements and a custom plan. Remember, our team at RenoFi is committed to finding a plan that fulfills your desired needs and provides a functional living solution for every occupant.

What to Consider When Designing 1 Bedroom ADU Floor Plans

Deciding on the floor style is just the first of the many steps required to design the perfect 1 bedroom ADU floor plan. It is significant to consider various other factors that ensure the finished ADU satisfies all your needs and complies with the local regulations and homeowner’s requirements. These considerations include:

Dimensions of the Lot

The style, size, and location of the 1 bedroom ADU depends entirely on the dimensions of the lot. For narrow spaces, a two-story or loft-style ADU works best, whereas larger lots usually feature two bedrooms for enhanced space and flexibility.

Local Zoning Laws

The location of the main property plays a vital role in determining the design of the ADU floor plan. Every municipality has its own set of rules regarding the construction of ADUs, including details such as the minimum and maximum area, kitchen requirements, and height restrictions. For example, in California, ADUs can be constructed up to 1200 sq ft on real estate properties with a setback of 4’ on the sides and rear. Understanding these laws before designing the floor plan lowers the chances of having to pay hefty fines in the future.

Budget Restraints

Building a 1 bedroom ADU requires thorough planning and a good grasp of your finances. A budget must be set aside to cover the expenses involved in its design, construction, and landscaping process. Another crucial detail here is to select the materials for the ADU between traditional slab to pier options and allocate extra allowances to cover other unexpected costs.

Types of the Occupants

The type of people that will occupy the ADU play a pivotal role in deciding on the final floor plan. For instance, if the ADU is designed to serve as a rental unit, then it is suggested to build a separate entry and install windows and other features while keeping in mind privacy concerns. Alternatively, if the ADU is going to serve as housing for guests, older adults, or children, a more welcoming and inclusive design can be used. 

Another factor to consider is the special needs and requests of the occupants. For older people or those with mobility issues, the ADU should consist of wide doorways and easily accessible bathrooms. It is also recommended to include a deck or patio in the floor design if the occupants prefer to have an outdoor living area.

Essentials to Maximize Comfort in 1 Bedroom ADU Floor Plans

Every 1 bedroom ADU floor plan must be designed to make efficient use of the space at the same time as providing functionality and extreme comfort to the occupants. To achieve these goals, here are some important design tips and essentials that can level up the quality of any 1 bedroom ADU floor plan in no time:

Use Durable Materials

The best 1 bedroom ADU floor plan strikes the right balance between budget and high-quality materials. Try to use concrete flooring, quartz tabletop, and other functional materials that protect from daily wear and tear activities and are low-maintenance. If you are on a tight budget, consider the Scandinavian or traditional style, both of which offer a good mix of durable and affordable elements. 

Built-in Storage Solutions and Furniture

Storage containers, including cabinets, drawers, and shelves, are a great way to keep the ADU’s limited space organized. Basic kitchen appliances like a sink, hood, and stovetops can also make the living experience more convenient for rentals occupying the property permanently or for extended intervals. Another good idea is to swap out basic furniture with multipurpose solutions such as a sofa bed to make the most out of the ADU’s available space.

Incorporate Design Elements

A 1 bedroom ADU floor not being spacious enough is no excuse for it to be boring. With the use of the right design elements, the unit will not only feel larger but also cozy and homey to the residents. 

Start by deciding between a modern, minimalist, or conventional look based on the architectural style of the main house and your personal preference. Opt for soft, lighter colors on the walls and install windows or skylights to keep the space breezy and well-lit throughout the day.

Address Privacy Concerns

Whether the ADU is designed for rentals or family members, there still needs to be measures to guard against privacy breaches. Focus on a floor plan that offers a distinct entrance to the occupants from that of the main house. 

The use of reliable insulation and solid doors can also help make the dwelling soundproof. Privacy screens and landscaping are also ideal, aesthetic solutions to address security problems in case the ADU is situated too close to the main property.

Other Details

Some other key points that can boost the individual’s living time in the dwelling unit include the installation of a fire and CO2 alarm, ductless mini splits for ventilation, and an electric water heater. 

When planning the layout of the 1 bedroom ADU floor plan, remember to keep in mind the flow of the space. Try to fill dead spaces with mirrors or multi-functional rooms and keep the kitchen and bathroom next to each other to lower the plumbing costs.

Frequently Asked Questions (FAQs)

What is the typical size of a one bedroom ADU?

What are the design considerations for an ADU floor plan?

Paying extra attention to the design and comfort of an ADU is a great way to elevate the living experience and thereby maximize the monthly rent.
