California ADU Law — What To Check Before You Convert

You May Be Able To Convert Your Garage
Without Building Replacement Parking.

Under California ADU rules, many garage-to-ADU projects may avoid replacement parking and use a simpler ministerial approval path. We review the city requirements before anyone promises feasibility, then handle the permit application, inspections, and code-compliance details if the project moves forward.

$150K–$300K+
Typical ADU value added to Silicon Valley homes
No Parking
Replacement required under SB 1211 — no city can force you to build new parking elsewhere.
1 Team
Design, permits, construction, and every inspection handled end-to-end

Garage ADU conversions typically range from $60K to $150K+ depending on scope, finishes, and whether plumbing is required. Start with a garage conversion estimate, then get a line-item estimate if it sounds like a fit.

You've heard the horror stories.

No Budget Surprises.
No Permit Headaches.
No Room That Still Feels Like a Garage.

Your Budget, Locked In Before Construction Starts

You receive a line-item estimate covering every cost before work begins. If anything changes during construction, you approve it in writing first. No end-of-project sticker shock. No "we found something" surprises that double the bill.

Every Permit and Inspection, Handled

Building permits, Title 24 energy compliance, city inspections, California ADU law requirements. We manage the entire process so you never visit city hall, never chase paperwork, and never worry about code violations down the road.

A Space That Feels Nothing Like a Garage

Proper insulation, ductless mini-split climate control, matched flooring, and real windows. We build to the same standard as the rest of your home. The result: a space where guests genuinely cannot tell it was ever a garage.

One Team From Design to Final Inspection

No juggling architects, permit runners, and separate contractors. Your dedicated project manager coordinates design, permits, construction, and every city inspection. One point of contact who answers the phone, start to finish.

What happens after you reach out?

4 Steps From Empty Garage
To Finished Living Space

01

We Evaluate Your Garage

Start with a garage conversion estimate. No on-site visit until you are ready for the next step.

Tell us what you need the space for, your rough budget, and your timing. If it sounds like a fit, we schedule the on-site visit to inspect the foundation, ceiling height, electrical panel, and structural condition. No sales pitch.

02

Your Design Takes Shape While Permits Move Forward

Your design team creates a layout that maximizes every square foot. You choose materials and finishes. Architectural plans and permit applications move simultaneously.

Nothing sits idle. While you work with your designer on the layout, materials, and finishes, our team submits architectural plans and permit applications to the city. You approve every detail before a single material is ordered.

03

Construction Stays on Track

Dust barriers on day one. A dedicated project manager you can actually reach. Regular updates so you always know what's happening.

Your dedicated project manager coordinates every trade, manages the schedule, and is available whenever you have questions. All city inspections are handled by our team. The entire crew is in a group chat so nothing falls through the cracks.

04

Move Into a Room That Was Always Meant to Be There

After a final walkthrough, the space is yours. Set up the office. Welcome your parents. List the rental. Everything is backed by a 2-year craftsmanship warranty.

Every detail is checked against your approved design. The space is cleaned, inspected, and ready. Invite the neighbors over. They will not believe it used to be your garage. Lifetime support after project completion for any questions or issues.
