What we resolve before drawings begin.

  • 01

    Title 24 + CALGreen + reach codes

    Many Bay cities have local reach codes above Title 24 (all-electric, EV-ready, solar). We design to them from day one.

    Geotech + drainage

    Every new build = soils + drainage. Hillside builds = caissons + slope stability.

Bay Area · New Construction FAQ

Questions Bay Area homeowners ask first.

Start a Bay Area new construction brief. We'll review the lot, engage architecture + soils, and write a design-build contract.

  1. What does Bay Area new construction cost?
    Typical custom single-family $700–$1,200 per sq ft all-in. Peninsula, hillside, and high-finish exceed this.
  2. How long does it take?
    Brief-to-keys typically 26–42 months: 8–12 months design + permit, then 18–30 months construction.
  3. Do you do small developments?
    Yes — 2–6 unit small residential under SB-9 lot splits, ADU-plus-main-house, small townhouses.
  4. Can I tear down and rebuild on my Bay Area lot?
    Usually yes. We confirm zoning, FAR, height limits, and any historic or design-review overlays during feasibility before signing the design-build contract.
  5. Do Bay cities require all-electric or reach-code construction?
    Many do — Berkeley, San Jose, Palo Alto, and others have reach codes above Title 24 (all-electric, EV-ready, solar). We design to the local reach code from day one, not retrofit at permit.
