Silicon Valley scale, fixed-scope discipline.

Mountain View has one of the most ADU-supportive frameworks in the Bay Area — pre-approved standard plans, a clear objective-standards path, and a building department that moves at a predictable pace. The economic case is strong: tenant demand from the Google / LinkedIn / 23andMe corridor keeps 1BR rents firm.

What we resolve before drawings begin.

  • 01

    Pre-approved standard plans

    Mountain View accepts a library of pre-approved ADU plans that cut plan-check time materially. We evaluate eligibility at feasibility.

  • 02

    Tree protection

    Heritage tree rules apply; siting around mature oaks and redwoods is a real design constraint.

  • 03

    Stormwater & green infrastructure

    New impervious area triggers stormwater mitigation; we engineer in C.3 compliance from day one.

Mountain View · ADU FAQ

Questions Mountain View homeowners ask first.

Start a Mountain View brief. We'll evaluate standard-plan eligibility, tree constraints, and a fixed-scope contract.

  1. Do Mountain View standard plans save real money?
    Yes — they cut design fees by $8K–$15K and plan-check by 4–8 weeks when parcel conditions match.
  2. Can my Mountain View ADU connect to existing electrical?
    Often yes if the panel is 200A. We confirm capacity calculation at feasibility.
