When considering the addition of an Accessory Dwelling Unit (ADU) to your property, one of the first questions to address is where to place it. The placement of an ADU involves more than just aesthetic and functional considerations; it must also comply with local zoning laws and building codes. Understanding these regulations can help ensure that your ADU project proceeds smoothly without unnecessary delays or complications. Dorothy Homes is here to provide guidance on how to smartly navigate these considerations for the optimal placement of your ADU.

Your property line defines the boundary between your property and your neighbor's. It is crucial to know these lines to determine where you can legally build your ADU. Encroaching on a neighbor's property can lead to legal issues and may require you to alter or remove the ADU after construction.

If you have a garage that sits on or near the property line, it is often possible to convert this space into a garage ADU. Many garages are built close to the property line, and local regulations may allow these structures to be grandfathered in for conversions, bypassing the typical setback requirements for new constructions.

For new detached ADUs, regulations usually specify a minimum distance from the property lines and the main residence. Generally, you cannot build a new detached ADU closer than 4 feet to the property lines. Additionally, a standard rule is that the ADU must be at least 10 feet away from the existing house. These setbacks ensure safety, privacy, and accessibility around the structures on your property.

Properties with overhead power lines, especially in areas serviced by utilities like Southern California Edison, have additional considerations. You cannot build your ADU directly underneath the drip line of these power lines. The drip line refers to the perimeter on the ground directly below the outer edge of the power lines, where water drips off the lines during rain. This restriction is for safety and ensures accessibility for utility maintenance.

However, the power drop — the line that runs from the utility pole to your house to provide electricity — can pass over the ADU. This allowance often provides more flexibility in placing your ADU, as long as the structure does not interfere with the safe operation and maintenance of the power drop.

When planning the placement of your ADU, consider not just the legal requirements but also the practical and aesthetic aspects of how the ADU will integrate into your property. Think about privacy, access, natural light, and how the placement of the ADU can enhance the overall functionality and value of your property.

Deciding where to place your ADU requires a balance of regulatory compliance, practicality, and vision for your property’s future. By understanding the rules around property lines, setbacks, and utilities, you can make informed decisions that streamline the development process and result in a more functional and harmonious addition to your home.
