Detached Accessory Dwelling Unit Construction in Los Angeles
Build a standalone backyard home in Los Angeles. We manage custom architecture, city permits, and ground-up construction with in-house crews.
About Our Team
Specialized Detached Accessory Dwelling Unit Builders
Our team specializes exclusively in backyard home construction across Los Angeles County. Since 2009, our craftsmen have built over 200 secondary living units.
A detached accessory dwelling unit creates private rental income or comfortable family living space. First, our licensed crews clear your site and trench dedicated utility lines. Next, we pour a reinforced concrete slab and frame structural shear walls. Because we handle all trades in-house, you avoid costly subcontractor delays. Furthermore, our project managers coordinate every LADBS building inspection directly. Consequently, your backyard cottage passes final inspection on schedule without hidden change orders.

Construction Process
How We Build Your Detached Accessory Dwelling Unit
Our in-house team guides your project through four clear engineering phases from initial soil evaluation to final keys.
Site Prep & Foundation
First, our survey crew marks setbacks and evaluates soil conditions. Next, we trench independent sewer laterals and pour a reinforced foundation slab.
Framing & Weatherproofing
Our carpenters erect structural wall framing and roof trusses. In addition, we install Title 24 dual-pane windows and weather-tight roof underlayment.
Mechanical Rough-Ins
Our licensed trades run electrical wiring, plumbing supply lines, and mini-split HVAC systems. Then, city inspectors verify all rough-in trades.
Interior & Exterior Finishes
Finally, our finish team installs drywall, cabinetry, countertops, and flooring. We complete city sign-offs to deliver your certificate of occupancy.
