Accessory Dwelling Units are quickly becoming a topic of interest for San Diego Homeowners. San Diego County allows ADUs and encourages their installation to help off-set the need for additional housing in San Diego County.

General Information on ADU (accessory dwelling unit) and prefab ADUs.

ADUs are often called "Granny Flats", "Tiny Houses" or "Backyard Cottages" due to their smaller size than the main home on the property. They can be legally installed/constructed and will increase the value of the homeowner's property. They can not be sold separately or as a subdivision of the primary property.

Why would you want an Accessory Dwelling Unit on your property? Most people like the idea as a means to generate additional income. They are also very comfortable accommodations for an aging parent(s). And let's not forget that they can help to increase your property value as they will appreciate with the value of your home.

ADUs can be installed or built within residentially zoned neighborhoods. We would suggest that you place a call to your local city planning department to confirm that allowance of accessory dwelling units in your city.

Thinking outside the box

Currently, there is a big push to have residents in San Diego install addition housing (namely ADUs / Prefab ADUs) as were running out of space. Overcrowding and the simple fact San Diego is such a desirable area in which to live. One possibility for residents looking to "down-size" is to move into the ADU yourself and then rent out your primary house. You could create a much larger income from your rental, which in turn could allow you to reinvest, travel, or pursue other things because of your newfound income source.
