100% Permit-Exempt Backyard Architecture
Every Boxpro Express shed model is custom designed and precision built to satisfy exact California Residential Code (CRC R105.2) and City of Yuba City Development Code guidelines for zero-permit residential installation.
120 Sq Ft Maximum Floor Area Limit
One-story detached accessory structures used as storage sheds, tool sheds, or home studios do NOT require a building permit provided the floor area does not exceed 120 square feet.
Under 12-Foot Peak Height Limitation
Permit-exempt residential accessory structures must remain 1-story with an overall height profile under 12 feet from finished grade to peak.
Pier Pad Foundation (No Permanent Concrete Slab Permit)
Structures built on high-density concrete pier pad matrices are classified as non-permanent elevated wood frame foundations, avoiding deep foundation excavation permits.
Property Line Setback & Fire Safety
Allows installation in side and rear yards provided a minimum 3-foot clearance is maintained from side/rear property lines. Real Western Red Cedar siding provides natural fire and rot defense.
Foundation, Site Prep & CSLB Contracting Compliance
Standard base builds on level pier blocks operate as non-permanent accessory structures. All custom site excavation, crushed rock pad grading, poured monolithic concrete foundation slabs, and structural builds exceeding statutory thresholds are executed directly through our licensed California General Building & Concrete Contractor network (CSLB Class B / C-8).
Hassle-Free Backyard On-Site Delivery & Assembly
No city plan submissions, zero architectural filing fees, and no waiting months for municipal approvals. Modular panels manufactured in-shop and delivered to your property across Yuba City, Marysville, Sutter, Plumas Lake, and Olivehurst.
