Crane Offload & Wing Unfolding Procedure

Watch the crane lift the folded unit from the flatbed trailer directly onto foundation piers, followed by the mechanical wing deployment.

Foundation Engineering

Approved Foundation Designs

Because the structural load is carried entirely by the heavy steel perimeter chassis and corner ISO castings, foundation requirements are simple and cost-effective.

Option A • Most Popular

Concrete Sonotube Piers

Augered cylindrical concrete piers poured below your local frost line. Requires 8 to 12 pier locations beneath the corner castings and wing support jacks. Most affordable option ($1,200–$2,800).

Option B • High Load

Concrete Strip Grade Beams

Continuous reinforced concrete grade beams poured beneath the central chassis rails and outer wing perimeters. Ideal for uneven terrain and rocky soil conditions ($3,000–$5,500).

Option C • Zero Concrete

Ground Screw Anchors

Industrial galvanized helical ground screws driven directly into the soil with hydraulic torque equipment. Zero excavation or curing time; ready to receive the home immediately ($2,500–$4,500).

State-Level Permitting & Zoning Regulations

State-by-State Zoning & Building Code Guidance

Zoning laws for modular and prefabricated homes have modernized dramatically. Here is what to expect in high-volume prefabricated housing states:

California

California ADU Permitting (SB 9 & AB 68)

California is the most progressive ADU state in the nation. Under statewide law, cities MUST approve compliant accessory dwelling units:

  • Setback Exemptions: Maximum 4-foot rear and side setbacks are mandated statewide.
  • No Owner-Occupancy: Cities cannot require the owner to live on the property to rent out the ADU.
  • Exempt from Impact Fees: ADUs under 750 sq ft are exempt from municipal development impact fees.
  • Plan Submission: Submit our stamped architectural CAD package for ministerial (by-right) plan review within 60 days.
Texas

Texas County-Level Zoning Freedom

Outside major municipal limits, Texas offers exceptional freedom for modular container homes:

  • Unincorporated Areas: No county zoning or building permits required on rural land in most Texas counties.
  • Septic Permitting: Only an OSSF (On-Site Sewage Facility) permit from the local county health department is needed.
  • City Jurisdictions: Major metros (Austin, Dallas, Houston, San Antonio) require standard IRC modular engineering plan submission.
Florida

Florida Wind-Load & DBPR Modular Rules

Florida requires compliance with high-wind hurricane engineering standards:

  • Wind Rating: Our units can be anchored with engineered cable tie-down systems rated for 130–150 mph wind gusts.
  • Modular Program: Pre-engineered stamped drawings must be submitted to the local county building authority.
  • Flood Zones: Units must be elevated to or above base flood elevation (BFE) on coastal properties.
Arizona & Sunbelt

Arizona & Desert Sunbelt Permitting

Fast-track accessory dwelling codes across Maricopa and Pima counties:

  • Phoenix / Tucson ADUs: Both cities have enacted dedicated accessory casita ordinances allowing detached guest suites.
  • Thermal Mitigation: Our Low-E double-glazed windows and insulated roof cores keep cooling loads efficient in desert heat.
  • Utility Simplicity: Direct 120V/240V hookups connect easily to primary residential electric panels.
