California and New York Tighten Security Deposit Rules; Colorado Leads 2026 Reform Wave
California has capped security deposits at one month's rent (AB 12), mandated photo documentation before and after tenancy (AB 2801), and starting January 1, 2026, requires electronic refund options (AB 414). Colorado's new tenant protections, effective January 1, 2026, prohibit landlords from retaining deposits for pre-existing damage and require documentation delivery within 14 days of tenant request.
Nationwide Deposit Cap Trend
State-level security deposit regulations have been tightening across the country, creating compliance challenges for landlords, and these rules are constantly being updated. Deposit amounts, return timelines, and deduction rules are governed by state law and vary significantly across the U.S.
Major State Changes in 2026
New York: The Housing Stability and Tenant Protection Act of 2019 limits landlords to requesting a security deposit equal to one month's rent. For buildings with six or more units, deposits must be held in an interest-bearing account at a New York bank, with interest credited to tenants minus a 1% administrative fee. Landlords must provide an itemized statement and return deposits within 14 days of lease termination.
California: AB 12 limits deposits to one month's rent, AB 2801 requires photo documentation before and after tenancy, and AB 414 mandates electronic refund options starting January 1, 2026. The 21-day rule requires landlords to return deposits or provide an itemized statement of deductions within exactly 21 calendar days of tenant move-out.
Colorado: New protections effective January 1, 2026, prohibit landlords from retaining deposits for pre-existing damage and require landlords to deliver relevant documentation within 14 days of a written tenant request.
What this means for newcomers: As a renter or prospective tenant, these laws increasingly protect you from unfair deductions and provide faster refund timelines. When signing a lease, especially in California and New York, request an itemized walkthrough and photograph the unit on move-in to protect against false damage claims. In Colorado and other reform states, understand your right to documentation of any pre-existing damage your landlord claims. Always keep copies of your move-in inspection photos and the lease agreement—compliance has tightened, and landlords face penalties for violations.
