Stormwater inspectors on permitted sites increasingly want portable toilets staked down so a tipped unit cannot drain into the swale or pond. Buyers on construction forums say they would pay $30 to $40 for it, and companies do it as a service call.
Two to four stakes through the unit's skid or a strap kit anchored into the ground. It takes a crew 10 minutes at delivery. Some companies include it on request; most price it as a service call.
Tick "SWPPP staking" in the notes on the quote form and every company quoting your site prices it up front.
Not by a statewide rule. It comes from the site's stormwater pollution prevention plan and the inspector enforcing it.
No. Stakes keep a unit upright in wind and foot traffic; a hurricane warning still means strap, sandbag or pull.
