The permitted distance of an ADU from the property line varies by city. In general, the minimum setback ordinances are typically 4 feet or more. Check with the development office of your local municipality to confirm your zone’s regulations for building ADUs.
Accessory Dwelling Units (ADUs) are becoming an increasingly popular option for homeowners looking to add additional living space to their properties. One of the most important considerations when planning an ADU is understanding the setback requirements, which dictate how close to the property line you can build. This blog post will explore the various factors that influence these requirements and provide guidance on how to navigate them.
Understanding Setback Requirements
What Are Setbacks?
Setbacks are the minimum distances that a structure must be from property lines. These requirements are designed to provide space between buildings for various reasons, including privacy, safety, and aesthetics. Setbacks can vary depending on the type of property and local zoning laws.
Types of Setbacks
Different types of setbacks may apply to your ADU project:
Front Setback: Distance from the front property line to the ADU.
Side Setback: Distance from the side property lines to the ADU.
Rear Setback: Distance from the rear property line to the ADU.
Local Zoning Regulations
Each city and county may have its own specific rules regarding setbacks for ADUs. It’s important to check with your local planning department to understand the specific requirements for your area. These regulations can significantly impact where you can place your ADU on your property.
Common Setback Requirements
While setback requirements can vary, some common guidelines include:
Front Setback: Typically ranges from 15 to 25 feet.
Side Setback: Usually between 4 to 10 feet.
Rear Setback: Often ranges from 5 to 15 feet.
Exceptions and Variances
Applying for a Variance
In some cases, you may be able to apply for a variance if you cannot meet the standard setback requirements. A variance is a request to deviate from the set rules due to unique circumstances. The process for obtaining a variance typically involves submitting an application and attending a public hearing.
Special Considerations
Certain conditions, such as irregularly shaped lots or existing structures, may affect setback requirements. It’s important to work with local authorities and possibly a land surveyor to understand how these special considerations might apply to your project.
Planning Your ADU Project
Consulting with Professionals
Consulting with professionals, such as architects, builders, and zoning experts, can help ensure that your ADU project complies with all setback requirements. These professionals can provide valuable insights and help navigate the permitting process.
Pre-Construction Checklist
Before starting construction, consider the following checklist:
- Verify local setback requirements with the planning department.
- Obtain necessary permits and approvals.
- Consult with a land surveyor to accurately determine property lines.
- Work with an architect or builder to design the ADU within setback limits.
Understanding setback requirements is a crucial step in planning an ADU project. By familiarizing yourself with local regulations, consulting with professionals, and preparing thoroughly, you can ensure that your ADU is both compliant and optimally placed on your property. Proper planning will help you avoid potential issues and make the most of your additional living space.
