ADU Types We Frame

Every Type of ADU Framed Right

San Jose and Milpitas have high ADU demand. We frame every configuration — and we know the Bay Area permit process.

🏠

Detached ADU Framing

Stand-alone ADU structures from slab to roof. We frame detached ADUs from 400–1,200 sq ft, including all interior walls, floor systems, and roof framing.

🏢

Garage Conversion Framing

Converting your Bay Area garage to an ADU is one of the fastest paths to rental income. We frame new walls, insulation-ready cavities, and proper window/door openings.

🔗

Attached ADU Framing

An attached ADU shares a wall with the main home. We tie the new structure into your existing framing properly — load paths, shear walls, and all.

🪄

Junior ADU (JADU) Framing

Smaller conversions within the existing home footprint. Bedroom conversions, studio configurations — permitted and inspected.

Our Process

From Estimate to Framing Inspection

Free Estimate

Review your plans or visit the site. Clear written estimate at no charge — within 24 hours.

Plan Review

We review your ADU drawings and identify any structural or framing challenges before breaking ground.

Permit Pull

We coordinate with the City of San Jose or Milpitas building department and pull the framing permit.

ADU Framing

Our licensed crew frames your ADU efficiently — walls, roof, window/door openings, shear walls.

Inspection

We pass the framing inspection. Every connection, every bolt, every block is inspection-ready before we call for inspection.

Handoff

Once inspection passes, your ADU framing is ready for the next trades: electrical, plumbing, drywall.

Bay Area ADU Market

Why the Bay Area is Perfect for ADUs

San Jose and Milpitas are among California's most ADU-friendly jurisdictions. State law (SB9, SB13) plus local ordinances make it easier than ever to add an ADU to your Bay Area property.

High Rental Demand

Bay Area rents are among the highest in the US. An ADU can generate $2,000–$3,500+/month in rental income in San Jose.

SB9 & Streamlined Permits

California state law streamlines ADU permitting. Many San Jose and Milpitas ADUs qualify for ministerial (fast-track) approval.

Property Value Boost

A properly permitted ADU adds significant value to Bay Area properties — often $200,000–$400,000 or more.

No Owner-Occupancy Required

San Jose removed owner-occupancy requirements for ADUs through 2025, making ADU investment easier than ever.

"Great experience framing that ADU in Milpitas. ADU construction in the Bay Area is something we really enjoy — every project is unique and we love the challenge."
