Buyer FAQs

Common Tier Questions Answered

Can I start with Tier 1 and upgrade to Tier 3 later?

Yes. All our structures are framed with standard 2x4 studs at 16″ on-center and double radiant barrier decking. You can easily add R-13 insulation, drywall, and a mini-split down the road, or have our crew return to execute Phase 2.

Why is Tier 3 ($14,850) the most popular choice for home offices?

Because it solves the extreme 105°F NorCal summer heat completely out-of-the-box. It includes the 9,000 BTU Inverter Mini-Split, professional smooth painted walls, commercial waterproof flooring, and full-lite doors. National prefab brands charge $38,000+ to $45,000+ for the same turnkey package.

How does Tier 4 Off-Grid work without digging up my yard?

Tier 4 pairs the Turnkey Suite with an Anker SOLIX F3800 lithium power station (3.84 kWh) and an 800W rooftop solar array. It generates and stores all the energy needed to power the mini-split, computers, 75″ TV, and LED lighting, eliminating the need to trench through existing concrete, patios, or landscaping.

Is a building permit required in Sutter or Yuba County?

No. Under California Residential Code (CRC § R105.2), detached one-story accessory structures of 120 square feet or less do not require a building permit. That means zero city hall delays, zero inspector walk-throughs, and hand-framed delivery in 1 to 4 days.
