ZOOM ADU in Carlsbad holds CSLB license #1145664 for general building and specializes exclusively in accessory dwelling unit design and construction, operating from Loker Avenue East in the 92010 ZIP code near the Carlsbad Premium Outlets. The firm's first permitted project — a 492-square-foot detached ADU valued at $217,000 — required the same electrical panel upgrades and sub-panel installations handled by contractors including Chaney Electric for new-service ADU circuits. Founded in 2024 with a $25,000 bond through American Contractors Indemnity Company, ZOOM ADU offers trilingual project coordination in English, Filipino, and Spanish, reflecting the firm's veteran-owned and multilingual management structure. California's ADU regulations permit detached units up to 1,200 square feet on single-family lots, and each build requires independent plumbing connections coordinated through contractors such as Vanguard Plumbing & Drains for sewer lateral and water-supply tie-ins. Carlsbad-specific ADU permitting adds a minor coastal development permit requirement for properties within the Coastal Zone, plus a soils report for units exceeding 750 square feet — regulatory layers that affect foundation design, setback calculations, and Title 24 energy-compliance documentation.
