Who we are

More homes, on lots that are already here.

SoCal Realty Holdings buys homes across Southern California that have room to grow, and adds new homes to them through SB 9 lot splits, ADUs and garage conversions.

We plan each project, take it through permits and build it. When the work is finished, we keep the homes as long-term rentals or sell the property.

How we work

From an existing lot to finished homes.

We buy the property, plan the new homes, get the permits and build them. Then we rent them out or sell.

Start to finish

Buy, plan, permit, build.

Each property goes through every step with us, from the day we buy it to the day the new homes are rented or sold.

What we do

Four ways we add homes in Southern California.

Every one of these is happening on one of our properties right now.

SB 9 Lot Splits

Splitting one single-family lot into two under California's SB 9, so each can hold new homes. At 452 Naples St, one lot became two.

ADUs

New accessory dwelling units, including manufactured ADUs set on new foundations, from compact two-bedroom homes to three-bedroom units.

Learn more

Garage Conversions

Turning an existing garage into a full home. At 429 Naples St, the garage becomes a two-story, three-bedroom ADU.

Learn more

Renovations

Updating the existing house on the lot. At 4003 Paula St we remodeled the main house and added an ADU before selling the property.

What we build

Three ways to add a home.

Each one is under way on one of our Chula Vista properties. Images are illustrative.

One lot becomes two

At 452 Naples St the original lot was split under SB 9, creating 454 Naples St next door. The existing house stays; a new ADU and a new primary home with its own ADU are added.

  • California's SB 9 lets many single-family lots be split into two, so each can hold new homes. At 452 Naples St in Chula Vista we split one lot into two and are adding three new homes next to the existing house.
