ADUs are quite the buzz word lately as LA County has recently impossed rules and regulations making it much easier to build or create a 2nd
unit on a property. These ADUs or Accessory Dwelling Units are basically a 2nd dwelling on the property with a full kitchen, bathroom and bedroom, which can be rented, leased or used for family. An ADU can be attached, detached, or even a converted garage. They are part of the property, however, and cannot be sold separately from the primary residence. In addition they must use existing utility connections and meters. While there cannot be more than one address on the parcel, ADUs may have a unit number or letter to differentiate the mailing address. Current regulations prohibit local agencies from imposing an owner-occupant requirement until January 1, 2025. Whether you love the idea or hate the idea really comes down to your situation and neighborhood.
Pro’s:
- ADUs can provide an additional source of income for homeowners.
- ADUs are generally inexpensive to create as they do not require paying for land.
- ADUs allow extended families to be near one another while maintaining privacy and not sharing the same space.
- ADUs give homeowners the flexibility to share independent living areas with family members and others, allowing seniors to live in their own space or younger family members to move in….without moving in to the same space.
Cons:
- ADUs may create parking problems in areas with limited parking….and generally speaking parking is always a challenge in the South Bay
- ADU’s may create overcrowding, and dramatically change the look and feel of neighborhoods.
- ADU’s will likely more road congestion as roads originally designed for a limited number of people may not be able to accomodate an influx of new residents.
- ADU’s could potentially lower property values and end the single-family “neighborhood” feel. Low density residential areas may loose that charm.

generally priced well below similar homes that don’t have age restrictions. Many of the complexes were built in the past 20 years and have a very updated and current look and feel more like vacation style hotels than senior living condos. Take a look below at just some of the options and communities in the area.
even within these cities the individual neighborhoods vary quite a bit and the Golden Hills is a great example in Redondo Beach. Unlike the rest of North Redondo Beach, the Golden Hills is almost exclusively single family homes.
