Security Deposit Return Deadline in California

In California, a landlord must return your security deposit within 21 calendar days after move-out. Missing this deadline often forfeits the landlord's right to keep any portion of the deposit, and many California tenants recover additional statutory damages for bad-faith withholding.

California HOA Law

HOA fines and assessments in California are governed by the Davis-Stirling Common Interest Development Act (Civil Code §4000–6150). This law generally requires written notice, an opportunity to be heard, and documented evidence before a fine becomes enforceable.

California Utility Regulator

Utility billing disputes in California fall under the California Public Utilities Commission (CPUC) — cpuc.ca.gov. Your utility generally cannot disconnect service while a formal billing complaint is pending with the regulator.

Key California Consumer Statutes

• Security Deposit: Civil Code §1950.5 — 21 days to return; 2x penalty for bad-faith withholding
• HOA Disputes: Davis-Stirling Act requires pre-litigation IDR and binding arbitration options
• Medical Billing: Health & Safety Code §1288 — right to itemized bill within 5 days of request
• Debt Collection: Rosenthal Fair Debt Collection Practices Act extends FDCPA to original creditors
• Utility: CPUC has formal complaint process; utility cannot disconnect during investigation
