TPJ Architecture in Chula Vista holds California architect license C-24012 and has designed residential projects across San Diego's South Bay since 1977, with a current focus on home remodels, room additions, custom houses, and accessory dwelling units. ADU design has become the firm's fastest-growing service line, producing detached, attached, and above-garage companion units that generate rental income for homeowners — a housing-density strategy that dovetails with the property management pipeline at Tenant Planet - Chula Vista Property Management. The published guide Cut the Chaos: The Ultimate Guide to Residential Remodeling distills the firm's construction-document and permitting process into a step-by-step framework covering preliminary design through contractor selection. Full-service project delivery runs from schematic design through construction administration, with MEP coordination routing ductwork and equipment placement through mechanical consultants — system-layout decisions that downstream HVAC installers at Air Pro Heating & Air execute during the build phase. Recent permit filings include JADU conversions, detached companion units, and two-story residences across southeastern San Diego, Skyline-Paradise Hills, and Normal Heights. Construction document sets include California Building Code Title 24 energy-compliance calculations, CalGreen checklist submittals, and ADA path-of-travel analysis scaled to current City of Chula Vista Development Services review standards.
