4-Bedroom ADU Floor Plans for California Homes
A 4-bedroom ADU is a smart solution for California homeowners who need maximum living space within a compact, code-compliant footprint. Whether you’re planning housing for extended family, long-term rentals, or a flexible live/work setup, our 4-bedroom ADU floor plans combine thoughtful design with efficient use of space—without exceeding the state’s 1,200 sq ft limit.
We specialize in developing ADUs that meet California’s zoning rules, Title 24 energy standards, and local permitting requirements in cities like Los Angeles, Santa Barbara, and Orange County.
What’s Included in Our 4-Bedroom ADU Plans
- Smart schematic layouts that fit four bedrooms within 1,200 sq ft.
- Complete construction drawings ready for permit submission.
- Title 24 energy compliance documentation.
- Structural and engineering coordination (optional).
- Lot-specific adjustments for zoning and site fit.
Types of 4-Bed ADUs We Offer
Detached 4-Bedroom ADUs: Standalone units that provide maximum privacy and flexibility—perfect for rentals, guest houses, or multigenerational living.
Two-Story 4-Bedroom ADUs: Smart vertical layouts that fit four bedrooms within the 1,200 sq ft limit while preserving outdoor space.
Attached 4-Bedroom ADUs: Units connected to the main home but designed as fully self-contained residences with separate entrances and utilities.
Fully Code-Compliant, Permit-Ready Plans
All of our 4-bedroom ADU designs are developed to meet California’s building codes, Title 24 energy standards, and local zoning regulations. We create complete construction drawings in-house and provide full support throughout the permitting process.
From site analysis and schematic layouts to final plans and engineering coordination—we handle every step. We also submit plans to the city and work directly with permitting offices to secure approvals quickly and efficiently, so your project stays on track.
