About Warren
Development

Six answers covering credentials, history, service area, and how we run projects — the questions homeowners ask most.

  1. 01

    Are you licensed and insured?

    Answer

    Yes. Warren Development is a licensed general contractor, fully insured and bonded to build in California. License documentation and insurance certificates are available on request.

  2. 02

    How long have you been in business?

    Answer

    Warren Development was founded in 2021. In that time we've built luxury custom homes, ADUs, complete remodels, pools, and outdoor living spaces across greater Los Angeles.

  3. 03

    What areas do you serve?

    Answer

    We serve homeowners across Santa Monica, Brentwood, Pacific Palisades, Westwood, Beverly Hills, Venice, Malibu, Calabasas, and Marina Del Rey — within 25 miles of our Santa Monica base.

  4. 04

    How do I get started?

    Answer

    Call us at (855) 505-1195, Sunday through Saturday, 6am to 7pm. We'll talk through your project, answer your questions, and schedule a free on-site estimate at your convenience.

    Do you work with subcontractors or your own crew?

    Answer

    We work with a trusted network of trade partners we've vetted and work with consistently. Every trade on your project is managed by Warren Development — you deal with us, not a rotating cast of contractors.

  6. 06

    Do you take on both residential and commercial projects?

    Answer

    We work primarily with homeowners on residential projects — new construction, remodels, pools, and outdoor living. We do consider commercial projects on a case-by-case basis. Call us to discuss.
