    Los Angeles County

    From Malibu to Pomona and the Valley to Long Beach. Costs swing about 30% city to city, driven by coastal premiums, hillside lots, and fire-rebuild demand in the Palisades and Altadena.

    Questions about where we work

    Which counties does Keystone Connect serve?

    Seven Southern California counties: Los Angeles, Orange, San Diego, Riverside, San Bernardino, Ventura and Santa Barbara. That covers all 210 incorporated cities in those counties, plus 26 neighborhoods and unincorporated communities such as Sherman Oaks, Altadena, La Jolla and Montecito.

    What does an "outlying" district mean?

    Outlying districts (the Antelope Valley, Catalina, the Coachella Valley and Blythe, the High Desert and Big Bear, San Diego's backcountry, and northern Santa Barbara County) are places where we recruit builders separately because the drive from the metro areas is long. We still take projects there. Expect a little more time to line up walkthroughs.

    Is the service free everywhere you work?

    Yes. Homeowners never pay Keystone Connect, in any county. You pay only the builder you choose to hire.

    My city isn't listed. Can you still help?

    If your home is in one of the seven counties, call (818) 482-8365 anyway. Unincorporated areas go by many local names and we cover the whole county, not just the places on this page.

    We'll line up two or three licensed builders who already work in your area.
