LBMC Title 21 caps single-family floor area ratio and bulk to prevent oversized homes from overshadowing neighbors, with stricter limits in coastal and historic districts.
Long Beach addresses mansionization through Title 21 zoning standards. Single-family R-1 districts have a base floor area ratio between 0.45 and 0.55 depending on lot size, with second-story step-backs and daylight planes that limit bulk near property lines. The Local Coastal Program in LBMC Title 17 imposes tighter coastal-zone height and lot coverage rules to protect ocean views, and historic districts like Bluff Park, California Heights, and Rose Park layer Mills Act and design review requirements. Projects exceeding base FAR may pursue conditional use permits with neighborhood notice, and Coastal Zone projects need Coastal Development Permits.
Construction beyond approved envelope triggers stop-work orders under LBMC 18.18, mandatory plan revisions or removal, and civil penalties up to $1,000 per day under LBMC 21.21; coastal violations carry separate Coastal Act fines up to $15,000 per day.
