ADU Potential & Multigenerational Living in San Diego: Why It’s One of the Hottest Trends in Real Estate
In today’s market, ADU potential and multigenerational living are two of the most searched terms in San Diego real estate—and for good reason.
Families are rethinking how they live. Whether it’s aging parents moving in, adult children returning home, or homeowners looking to offset their mortgage with rental income, properties with Accessory Dwelling Units (ADUs) are in high demand across San Diego County.
As local experts serving Coronado, La Jolla, Rancho Santa Fe, Del Sur, and beyond, our team is seeing a major shift: buyers aren’t just asking about square footage anymore—they’re asking about flexibility.
What Is an ADU?
An Accessory Dwelling Unit (ADU) is a secondary housing unit located on the same lot as a primary residence. It may be:
- A detached guest house
- A converted garage
- A basement or attached unit with separate entrance
- A newly constructed backyard cottage
In California, ADUs have become increasingly popular thanks to updated state legislation making them easier to build.
Why ADU Potential Matters in Today’s Market
1. Rental Income Opportunities
With San Diego rental demand remaining strong, an ADU can provide:
- Supplemental monthly income
- Long-term rental stability
- Short-term rental potential (where permitted)
- A hedge against rising mortgage costs
Many buyers are specifically searching for homes with existing ADUs or lots that allow future ADU construction.
2. Multigenerational Living Is Growing
According to national housing trends, multigenerational households are at record highs—and San Diego is no exception.
ADUs offer:
- Private space for aging parents
- Independence for college-age children
- Room for live-in caregivers
- Flexibility for long-term guests
Instead of sacrificing privacy, families gain autonomy while staying connected.
3. Long-Term Property Value
Homes with ADUs often:
- Command higher resale values
- Attract a wider buyer pool
- Offer multiple exit strategies (rent, sell, occupy)
In competitive neighborhoods like Coronado or Del Sur, properties with legal ADUs are often among the most sought-after listings.
Where We’re Seeing ADU Demand in San Diego
We’re consistently seeing interest in:
- Large-lot properties in North County
- Homes with detached garages ready for conversion
- Corner lots with separate access
- Single-level homes ideal for extended family use
Many buyers specifically ask about:
- Lot size requirements
- Zoning allowances
- Parking regulations
- Owner-occupancy rules
- Coastal Commission restrictions (in beach communities)
Understanding these details is critical before purchasing with ADU plans in mind.
Should You Build an ADU?
If you already own a home in San Diego, adding an ADU can be a powerful investment strategy. However, it’s important to evaluate:
- Construction costs
- Permit requirements
- Utility connections
- Impact on property taxes
- Neighborhood restrictions
We frequently advise clients on whether adding an ADU makes financial sense based on their long-term goals—whether that’s retirement income, family support, or resale positioning.
What Buyers Should Look for in an “ADU Potential” Property
When we help clients search for ADU-friendly homes, we focus on:
✔️ Lot size and usable yard space
✔️ Alley or side access
✔️ Existing detached structures
✔️ Utility placement
✔️ Zoning and overlay regulations
✔️ HOA restrictions
Not every property marketed as “ADU potential” truly qualifies—this is where working with an experienced local team makes a difference.
The Future of Housing in San Diego
As housing affordability continues to challenge buyers, flexible living solutions are becoming essential—not optional.
ADUs are helping families:
- Stay together
- Create financial stability
- Adapt to changing life stages
- Build long-term wealth
This trend is not slowing down.
