Security Deposit Deadline Calculator

Security-deposit deadlines are not the same across the U.S.

Our verified states include 14-day, 21-day, 30-day and 45-day frameworks, plus multi-step rules and exceptions. Florida separates no-claim and claim notices; North Carolina can require an interim accounting before a 60-day final accounting; Virginia has a narrow contractor extension; Arizona excludes weekends and legal holidays; Illinois uses separate 30-day and 45-day clocks; New Jersey has special accelerated timelines for defined situations.

What the calculator does

• Adds the ordinary calendar-day offset where that calculation is appropriate.
• Shows multiple dates when the state uses distinct normal and exception timelines.
• Links every result to the corresponding verified RentBillCheck state guide.
• Refuses to give a false-simple Arizona date because the state excludes weekends and legal holidays.
• Flags Illinois’s separate 30-day statement and 45-day full-return clocks instead of pretending they share one trigger.

What you still need to confirm

• The correct event that starts the deadline.
• Whether possession was legally returned or the tenancy was terminated on a different date.
• Forwarding-address requirements, lease extensions or special housing categories.
• Any city or county rule that adds tenant protections.
