Preparing a Parking Lot for an ADA Compliance Review

Why parking gets attention

Parking is the first thing a visitor encounters and it is one of the easiest things for an inspector or a complainant to evaluate. Stall counts can be verified by counting. Slopes can be verified with a level. Markings and signage are either present and legible or they are not.

Because it is easy to check, it is frequently checked. Faded striping, a missing sign, or an access aisle that has been allowed to disappear are the kinds of findings that come up over and over. Most of them are also inexpensive to correct compared to almost any other accessibility item.

What gets looked at

Count and distribution come first. The number of accessible stalls required scales with the total number of stalls in the lot, and a portion of them must be van accessible. They must be located on the shortest accessible route to the entrance they serve.

Geometry is next. Accessible stalls need an adjacent access aisle, and the aisle must be marked. Van accessible stalls have additional width and vertical clearance requirements. Slope is limited in all directions within stalls and aisles, which is a common failure on sloped mountain sites.

Then the route. There has to be a continuous accessible path from the stall to the entrance without steps, without excessive slope, and without obstructions. Curb ramps, detectable warnings where required, and door approaches all fall into this.

The things that quietly fall out of compliance

Striping fades. This is the big one in our climate. Plow blades and traction sand wear paint fast, and an access aisle with no visible hatching stops functioning as an access aisle. Symbols and stall lines go the same way.

Signs go missing, get bent by plows, or end up mounted too low. Snow piles get stacked in accessible stalls and aisles, which defeats them entirely during the months they may be needed most. Pavement deterioration also matters, since potholes, wide cracks, and settled areas along the route create hazards and slope changes.

Restriping a lot without checking the layout is another quiet failure. If the lot is repainted to match faded lines that were wrong in the first place, the error just gets refreshed.

A practical sequence

Walk the lot with the requirements in hand and measure rather than eyeball. Count stalls, check aisle widths, check slopes with a level, verify sign heights, and walk the route from the farthest accessible stall to the door.

Fix pavement defects along accessible routes before restriping. Sealcoating and striping go together, in that order, and layout should be reviewed at that point rather than copied blindly. Get snow removal instructions in writing that keep accessible stalls and aisles cleared and never used for storage.

The requirements themselves come from the ADA Standards and the California Building Code, and California requirements are in places more stringent than federal ones. For a specific lot, a qualified accessibility specialist is the right person to interpret them. What we can do is the pavement side, meaning surface condition, sealcoating, and striping and markings.
