San Marino Additions That Pass a Mandatory Design Review Board
San Marino Addition 2026 Pricing and Design Review Board Reality
A 350 to 600 sq ft estate-grade addition in San Marino runs $250,000 to $380,000. A 700 to 1,200 sq ft addition lands $380,000 to $540,000. A 1,300+ sq ft major addition or second-story stack runs $540,000 to $680,000+. Per-square-foot, San Marino additions sit between $400 and $900/sf — the highest band of any market we cover, because every element is custom-millwork to period-correct profile, the Design Review Board mandate raises design and submission cost, the trade rates here reflect the estate-grade work expected, and the finish spec is typically two or three tiers above any other LA market. DRB submission and review is a real line item — the package includes streetscape elevation studies, period-vocabulary analysis, material samples, and color renderings, and the typical review cycle is 8 to 14 weeks including a DRB hearing. Period-correct addition spec we design to: Mediterranean roof tile and stucco detailing matching original profile, Spanish Revival arched openings and clay-tile ridge cap, Georgian symmetry and proportion with original-vocabulary casing and cornice, English Country masonry and steep-pitch roofline. Estate-grade interior finish standard: solid-wood inset cabinetry, stone counters with period-appropriate edge profile, period-correct hardware in solid bronze or polished nickel, custom millwork throughout, integrated lighting and shading systems. NPLD designs to DRB standards from day one, manages the DRB submission and hearing process, permits through San Marino Building & Safety, runs every trade, warranties 10 years structurally.Home Addition Questions Homeowners Ask About Home Addition in San Marino
