👨‍🔧 Sewer, water, gas — the lines your house can’t live without, and the only stage you’ll never see again after this week. Slope on the sewer has to be right (too flat won’t drain, too steep leaves solids behind), water lines get pressure-tested, gas gets its own inspection before anything is covered.

🏗️ Joists, subfloor, walls up — the skeleton phase moves fast, but nothing here is rushed. Every stud plumb, every header sized for its load, every shear panel nailed to spec. Because once drywall goes up, only the work that was done right survives.

🏡 First floor framing done on our San Gabriel custom home + ADU build. This stage decides how straight, square, and solid everything else will be.

Oak, soft-close everything, and every box leveled and shimmed by hand — this is the part of the build where it starts feeling like a home.

Cabinet install is where good planning pays off. Measure twice at rough framing, and everything drops in clean months later.

What people don’t see before a new build 👇

By the time a house looks like a house, the hardest work is already buried. Weeks of trenching, rebar, underground plumbing, pressure tests, and inspections — all underneath before the first wall goes up.

The finished home gets the photos. This is what holds it up. 🏗️

Ever wonder what happens before a house even looks like a house? 🏗️

The first 3 steps every big build starts with:

1️⃣ Foundation footings + underground plumbing — the bones and veins go in first

2️⃣ Concrete footing pour — locked in and inspected

3️⃣ Slab pour — the floor your whole home stands on

Every city in the 626 has different ADU rules — and most homeowners don’t find out until they’re already deep into planning 👀

Swipe to see what’s allowed in your city →
Temple City, Arcadia, Rosemead, San Gabriel, El Monte, Alhambra, San Marino — all different rules, all different watch-outs.

The biggest surprises? Arcadia’s 50% rule and San Marino’s fire lane requirement. most people have no idea until it’s too late.

DM us your city and we’ll tell you exactly what you can build on your lot — free 👇

ADU build from start to finish 🤩

This was the timeline of our ADU project in Rosemead. Every project is different however — permits alone in LA county could take 3-6 months before the project is even able to begin, but this would be our average progress timeline after everything is approved and running.

🏠 1,200 sq.ft. | 2 stories
🛌 3 beds | 2.5 baths
🍳 Full kitchen + living room
⬆️ 11 ft ceilings
🧺 In-unit laundry
🚗 500 sq.ft. 2-car garage
📍 Rosemead, CA
