The studio rules

Four commitments behind every engagement.

  1. 01

    Fixed-fee feasibility, one business day

    Every engagement starts with a hardened cost + zoning + timeline brief — not an estimate range you can't act on.

  2. 02

    One-team design + build

    Architecture, engineering, plan check, and construction live under one P&L. No coordination tax, no finger-pointing on corrections.

  3. 03

    Real cost transparency

    Line-item budget at contract, weekly burn report during build, and a hard contingency we don't touch silently.

  4. 04

    CSLB-licensed California contractor

    CSLB #1156772. License, bond, general liability and workers' comp certificates are shared during your consultation and confirmed in writing before signing.

FAQ

Frequently asked questions

What homeowners ask before booking a feasibility on one of our six services.

  1. Which service is right for my lot?
    Detached ADUs maximize value when you have 1,200+ sq ft of clear yard. Garage conversions are the fastest path if your existing garage is permitted and structurally sound. JADUs work when you want rental income without giving up backyard space. We confirm the right fit during the one-business-day feasibility review.
  2. How long does the full design-build process take?
    Permit timelines run 8–22 weeks depending on jurisdiction and service type. Construction adds another 3–8 months. End-to-end, plan on 6–12 months from contract to certificate of occupancy for a detached ADU, and 4–7 months for a garage conversion or JADU.
  3. Do you handle the permits and plan check?
    Yes — every engagement includes architectural, structural, Title 24, and LADBS plan-check management end-to-end. We submit, track, and clear corrections under one P&L so you don't coordinate between separate firms.
  4. Are you licensed, bonded, and insured?
    CSLB #1156772. We carry general liability, workers' compensation, and an auto-renewing performance bond available on request. License and insurance certificates are shared at contract signing.
  5. Can I use my own architect or contractor for part of the project?
    Our permitting & design service (No. 06) is fee-based and supports homeowner-selected GCs. The other five services run as integrated design-build under one contract — that's where the cost certainty and schedule discipline come from.
  6. How does pricing compare to other LA design-build firms?
    Our published starting prices and per-sq-ft bands sit mid-market — we're not the cheapest bid and we don't try to be. The savings show up in fewer change orders, on-time delivery, and a hard contingency we don't quietly draw down.
