Tiny Home Associates in Chula Vista builds custom tiny homes and accessory dwelling units from its Hilltop Drive office in the 91911 zip code, serving San Diego City and Los Angeles County under California's expanded ADU regulations. Each project starts with a site assessment covering zoning designation, parcel setbacks, utility access, slope conditions, and easement verification—the same due-diligence sequence that informs the spatial planning at Luis Davalos Design for residential lot optimization. Formed as a California LLC in 2024, the firm constructs units approved for both primary-residence and ADU classification where local codes permit, with full fire-rating compliance and Title 24 energy documentation included in the delivery package. Electrical rough-in and panel upgrades for new ADU sub-panels route through contractors such as Arcelectric, Inc to ensure 200-amp service capacity meets the added load from a detached dwelling. Finished units arrive with spray-foam insulation assemblies, tankless water heaters, and pre-wired mini-split HVAC systems sized to California Climate Zone 7 Manual J load calculations.
