Verify 10-year sealed smoke detector and CO detector before each new lease. Louisiana law (La. R.S. 40:1581) requires every one-family or two-family dwelling, at each new lease, to contain at least one operable smoke detector with a ten-year sealed lithium battery and at least one operable carbon monoxide detector with a long-life sealed battery (a combination unit can cover both), so checking them before each tenant moves in keeps the home compliant and catches dead or missing alarms early.
