House Max is an architectural design consultancy in Grantville, San Diego at 4760 Mission Gorge Pl, 92120, led by Juan Quemado, a trained architect who holds a Bachelor of Arts in Architecture from the New School of Architecture and Design in San Diego. Quemado has maintained a private design practice since the early 2000s, producing residential and small-commercial plans that move through the City of San Diego's permitting process alongside firms at Schall Architects in Allied Gardens. Design services cover single-family home additions, ADU (accessory dwelling unit) plans, kitchen and bathroom remodels, and interior-layout reconfigurations — project types driven by the mid-century housing stock in Allied Gardens, Del Cerro, and San Carlos where original floor plans no longer match current household needs. Construction-document packages include site plans, floor plans, elevations, structural details, and Title 24 energy-compliance calculations required by California building code for all permitted work. The Mission Gorge Place office sits within the Grantville light-industrial corridor, a quarter mile east of Mission Gorge Road and within the 92120 ZIP. ADU design has become a primary workload as San Diego's AB 68 and SB 13 regulations expanded permitting pathways for backyard units on single-family lots — a housing category that investors and homeowners working with AJX Homes in Allied Gardens develop as rental-income additions. Quemado's drafting output uses AutoCAD and Revit software to produce permit-ready drawings that satisfy plan-check review at the City of San Diego Development Services Department.
