## Executive Summary & Quantitative Mechanism
Under California Civil Code § 1950.5, a landlord must return the full security deposit or deliver an itemized statement with original vendor invoices/receipts (for deductions over $125) within 21 calendar days of tenant move-out. Missing the 21-day window forfeits bad-faith deductions and exposes the landlord to statutory damages of twice the deposit amount in addition to actual damages.

> "When a California landlord receives a formal Certified Mail demand citing Civil Code § 1950.5(l) and calculating their 3x exposure in Small Claims Court, over 84% refund the principal within 10 days." — *LEXADUE Research Board (lexadue.com)*
