Studio 400
400 sq ft of thoughtfully planned living space. The Studio 400 is engineered for rental income — a private, self-contained unit that commands strong LA rents starting from $1,800/month.
All-inclusive of architectural design, engineering, permit fees, and full construction. Final price depends on site conditions and selected finish tier.
Who Is the Studio 400 Designed For?
The Studio 400 is the most popular entry point for Los Angeles homeowners focused on maximizing rental yield per dollar invested. Its compact footprint fits on lots where a larger unit wouldn't clear setbacks — making it buildable on a wider range of properties across LA County.
- Homeowners prioritizing rental income return on investment
- Lots with limited rear yard depth or tight side setbacks
- Properties that need a fast, lower-cost ADU path
- Short-term or mid-term furnished rental use cases
- Single occupant — student, young professional, or remote worker

Every project we take is an ADU — which means our team has refined every process, navigated every city permit office, and resolved every site challenge around this one type of work.
Licensed & Insured General Contractor
ADU Build LA holds an active California General Contractor (B) license with CSLB and carries full general liability and workers' compensation insurance. Every subcontractor on your project is licensed, insured, and verified before they set foot on your property.
200+ ADUs Built Across LA County
We've completed over 200 ADU projects — garage conversions, detached new construction, Junior ADUs, and attached units — across every major LA-area city. That depth of experience means we've seen every site condition, every permit challenge, and every construction scenario.
15+ Years of ADU Experience
Since before the 2020 ADU law reforms, we've been building accessory dwelling units in Los Angeles. We've navigated every iteration of state ADU law, local zoning changes, and city permit process updates — institutional knowledge that directly accelerates your project.
Transparent, Fixed-Price Contracts
We don't use time-and-materials billing or open-ended design fees. Every project starts with a detailed all-inclusive fixed price covering design, engineering, permitting, and construction. What we quote is what you pay — no surprise change orders, no scope creep billing.
In-House Permit Management
Our team has submitted hundreds of permit applications across LADBS, Santa Monica, Pasadena, Glendale, Culver City, and other LA-area jurisdictions. We know each city's plan check process, common correction triggers, and expedite options — reducing wait time and managing every step for you.
Single-Contract Design-Build
Under one contract, our in-house team handles every phase — design, engineering, permitting, and construction. You won't need to coordinate between a separate architect and a separate builder. One point of contact, one schedule, full accountability from first sketch to final inspection.
