Wyoming security deposit rules.
The Wyoming rules for residential security deposits in plain English: how much can be charged, how fast it comes back, whether interest is owed, and what catches operators out.
Last reviewed · Statute: Wyo. Stat. Ann. § 1-21-1208 · Not legal advice
How much can be charged
No statutory limit on the deposit amount.
When it has to come back
Within 30 days after termination or 15 days after receipt of the renter’s new mailing address, whichever is later, with written itemisation. If there is damage to the unit, the period is extended by 30 days.
Interest
No interest is required.
Where the money has to sit
No segregation requirement.
What catches operators out
- The extra 30 days applies automatically when there is damage to the unit; the statute imposes no written-notice condition for the extension.
- No statutory damages for bad-faith retention.
What this looks like with Standby in Wyoming.
When a resident takes a Standby certificate there is no cash deposit to hold, so the cap, the return deadline and the interest rules above have nothing to attach to. You are covered up to the full deposit and draw on it when you need to.
When a resident pays cash instead, Standby handles that deposit under your lease and Wyoming law, so your team is not tracking return deadlines by hand.
This page summarises the most common single-family and multifamily residential rule in Wyoming. Furnished units, senior leases, mobile-home tenancies and short-term rentals can differ, and city ordinances may override the state default. Check the statute before relying on a figure for a specific lease.
