ADA-compliant units are not interchangeable with a standard porta potty just because both sit on the same trailer. The door has to swing wide enough for a wheelchair or walker, the interior needs enough clear floor space to turn, and the unit has to sit on level, stable ground — which matters on a Dougherty Valley grading site where the pad hasn't been fully compacted yet, or on a Gale Ranch lawn where sprinklers have softened the turf. We check placement before drop, not after, because a unit set on a slope or loose gravel fails the access requirement even if the fixture itself is compliant.
GCs on Bishop Ranch Business Park sites request ADA units when a permit or inspection calls for accessible facilities alongside standard units for the crew — usually a mix of one ADA unit per bank of two or three standard units, not a one-for-one swap. Private hosts near Windemere or Norris Canyon planning a graduation party or estate sale with older or mobility-limited guests often want just one ADA unit near the house or garage, positioned for a short, flat walk rather than tucked at the back of a yard. Both cases hinge on the same thing: knowing exactly where the unit needs to sit before it arrives, because moving it after delivery costs time neither a jobsite nor a party has.
The trade-off with ADA units is availability and lead time — there are fewer of them in rotation than standard units, so events near Twin Creeks or Bridle Ridge with a fixed date benefit from booking as soon as the guest list or inspection date is confirmed rather than the week of. For jobsites along Crow Canyon Road or in Old Ranch subdivisions still under grading permits, we call ahead of the delivery window to confirm gate hours and site access, the same way we do for standard units, so the truck isn't sitting at a locked gate with an ADA unit no one can place yet.
We don't guess at unit count or placement over the phone. A quick conversation about guest count, site layout, or inspection requirements gets you a realistic price range up front, and the exact number gets confirmed before the invoice is written — no surprise line items at pickup.
