Wyoming Landlord-Tenant Laws
Wyoming Security deposits
Wyoming puts no cap on security deposits, and the landlord must return the balance with a written, reasoned itemization of any deductions within 30 days after the tenancy ends or within 15 days after receiving the tenant's new mailing address, whichever is later — and if the unit was damaged, the deadline stretches by another 30 days.
Wyoming Rent increase notice
Wyoming has no statute requiring any advance notice of a rent increase — and unlike most no-notice states, it has no statutory month-to-month termination notice to derive a working rule from either.
Wyoming Late fees
Wyoming sets no cap on residential late fees and mandates no grace period — no statute anywhere in Wyoming law addresses late charges on residential rent, so a late fee exists only if the rental agreement creates it, bounded by ordinary contract law rather than any statutory test.
Wyoming Entry notice
Wyoming has no statute requiring landlords to give advance notice before entering a rental unit — no 24-hour rule, no 'reasonable notice' standard, no emergency exception, and no time-of-day window exists anywhere in Wyoming law.
How this record was verified: Direct read of statute text from the official Wyoming Legislative Service Office statute files (wyoleg.gov/statutes/compress/title01.pdf, title34.pdf, title15.pdf, title40.pdf — the wyoleg.gov site is an SPA that serves its statute PDFs directly to curl; the Title 1 file reflects 2025-session repeals and is current through the 2025 General Session): Title 1 ch. 21 art. 12 (W.S. 1-21-1201 through 1-21-1211) and art. 10 (1-21-1001 through 1-21-1017) read in full, plus W.S. 34-2-126 through 34-2-132. Double-read via a second official endpoint: the LSO NXT infobase ('2021 Titles', wyoleg.gov/NXT/gateway.dll) article views for arts. 12 and 10 — the entire Article 12 text (12,872 normalized characters) is CHARACTER-IDENTICAL between the official 2021 edition and the official 2025 PDF. Deposit figures additionally triple-read against the Wyoming Judicial Branch's TENANT Form 03 instructions (wyocourts.gov, rev. Sept 2024), which reprint W.S. 1-21-1208 verbatim; FED figures corroborated by the Judicial Branch Eviction Handout; FindLaw mirror matched 1-21-1208 and 34-2-128 verbatim (Justia 403s automated fetchers). Verified negatives (no deposit cap, no interest or separate-account rule beyond the express 'without interest' clause, no rent-increase or periodic-termination notice statute, no late-fee cap or grace period, no entry-notice statute, no rent-control or preemption provision) run by full-article reads plus keyword sweeps of Titles 1, 15, 34 and 40 — zero occurrences of 'month-to-month', 'late fee', 'late charge' or 'grace period' in Titles 1/15/34. Mandatory session sweep on the official LSO bill API (lsoservice.wyoleg.gov): all 891 bills of the 2025 General and 2026 Budget Sessions enumerated by short title, and all 278 enacted chapters (171 of 2025, 107 of 2026) separately enumerated — zero on-topic enactments; dead bills 2025 HB0213 (owner utility duties) and 2026 HB0183 (renter tax relief) both 'Did not Consider for Introduction'. The 2026 Budget Session has adjourned; next regular session January 2027.
