Missouri sets no statutory notice period for a landlord to enter — the lease controls, and 24 hours' written notice is the standard every court treats as reasonable. Send it from the tenant's record so the date, the reason and the delivery are on file.
Pick the situation. The period on each card is Missouri's minimum — your lease can require more, never less.
No statutory period; follow the lease. Most Missouri leases specify 24 hours, and courts treat 24 hours as reasonable.
Allowed. Tell the tenant afterwards what happened and what was done.
Repairs, inspections, showing the unit to prospective tenants, buyers or contractors, and supplying agreed services.
Not a proper notice for a reason the lease allows. Repeated refusal is a lease violation; never enter by force.
Only if the lease allows electronic notices. The in-app message is emailed and shown in the tenant portal, time-stamped; print it for hand delivery where paper is required.
