Can be built on most properties
One of the great things about ADU floor plans 300 sq ft is that they can be built on most properties. This is because they are considered to be “accessory dwelling units” (ADUs). ADUs are typically smaller than the main house on a property, and they are designed to be used in conjunction with the main house. This means that ADUs do not need to meet the same building codes as main houses. As a result, they can be built on properties that would not be able to accommodate a larger home.
- Setbacks: ADUs are typically required to be set back from the property line by a certain amount. This setback varies from municipality to municipality, but it is typically between 5 and 10 feet. This setback ensures that ADUs do not encroach on neighboring properties.
- Height restrictions: ADUs are also typically subject to height restrictions. These restrictions vary from municipality to municipality, but they are typically between 15 and 20 feet. This ensures that ADUs do not block the views of neighboring properties.
- Other restrictions: ADUs may also be subject to other restrictions, such as restrictions on the number of bedrooms and bathrooms that they can have. These restrictions vary from municipality to municipality, so it is important to check with your local building department before you start planning your ADU.
- Exceptions: There are some exceptions to the rules governing ADUs. For example, some municipalities allow ADUs to be built on properties that are smaller than the minimum lot size. Other municipalities allow ADUs to be built without a setback from the property line. It is important to check with your local building department to see if there are any exceptions to the rules in your area.
Overall, ADU floor plans 300 sq ft can be built on most properties. However, it is important to check with your local building department to make sure that your property meets the requirements for ADUs.
May require permits and inspections
Depending on your local building codes, you may need to obtain a permit before you can build an ADU. The permit process typically involves submitting plans to the building department for review. The building department will then inspect the plans to ensure that they meet all of the applicable building codes. Once the plans have been approved, you will be issued a permit to build your ADU.
In addition to obtaining a permit, you may also need to have your ADU inspected by the building department. The inspection process typically involves the building inspector visiting your property to verify that the ADU has been built according to the approved plans. The building inspector will also check to make sure that the ADU is safe and habitable.
The permit and inspection process can help to ensure that your ADU is built to a high standard of quality and safety. It is important to note that the permit and inspection process can vary from municipality to municipality. It is important to check with your local building department to find out what the specific requirements are in your area.
If you are planning to build an ADU, it is important to factor the cost of permits and inspections into your budget. The cost of permits and inspections can vary depending on the size and complexity of your ADU. It is important to get a clear understanding of the costs involved before you start construction.
Overall, the permit and inspection process is an important part of building an ADU. It helps to ensure that your ADU is built to a high standard of quality and safety.

Windows and doors that are not properly sealed can allow heat and cool air to escape, which can increase your energy bills. Look for windows and doors that are Energy Star certified. Energy Star certified windows and doors are designed to be energy efficient.
- Appliances: The appliances you choose for your ADU can also have a significant impact on your energy bills. Look for appliances that are Energy Star certified. Energy Star certified appliances are designed to be energy efficient.

Design for accessibility
When designing your ADU floor plan, it is important to consider accessibility. This will make your ADU more accessible to people with disabilities, as well as to people who are aging in place.
- Wide doorways and hallways: Wide doorways and hallways are essential for people who use wheelchairs or other mobility devices. A minimum doorway width of 32 inches is recommended. Hallways should be at least 36 inches wide.
- No-step entrances: No-step entrances are essential for people who use wheelchairs or other mobility devices. A ramp or a zero-threshold entrance is recommended.

Maximize natural light
Natural light can make your ADU feel more spacious and inviting. It can also help to reduce your energy bills. There are a number of ways to maximize natural light in your ADU floor plan:
Use large windows and doors: Large windows and doors allow more natural light to enter your ADU. If you have the space, consider using floor-to-ceiling windows or sliding glass doors. These types of windows and doors can really open up your ADU and make it feel more spacious.
Place windows and doors strategically: When placing windows and doors, think about how the natural light will enter your ADU. Try to place windows and doors on the south side of your ADU, as this is the side that receives the most sunlight. You may also want to consider placing windows and doors in areas where you spend a lot of time, such as the living room and kitchen.
Use skylights: Skylights are a great way to add natural light to interior spaces. Skylights can be placed in any room, but they are especially effective in rooms with high ceilings. Skylights can also help to reduce your energy bills by providing natural ventilation.
