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
