ADA Parking Lot Striping in Boise, ID

ADA compliance is where a lot’s striping turns from cosmetic to legal. We lay out and mark accessible parking that meets the 2010 ADA Standards for Accessible Design — correct stall counts, van-accessible spaces, access aisles, symbols, and signage — so your property is compliant and defensible. Non-compliant accessible parking exposes a business to complaints and liability, and most violations come down to details that are straightforward to get right the first time.

How Many Accessible Spaces You Need

The number of accessible stalls is fixed by your total parking count under Section 208 of the 2010 ADA Standards for Accessible Design. It scales like this:

Total spaces in lot	Minimum accessible spaces
1 to 25	1
26 to 50	2
51 to 75	3
76 to 100	4
101 to 150	5
151 to 200	6
201 to 300	7
301 to 400	8
401 to 500	9
501 to 1,000	2% of total
1,001 and over	20, plus 1 per 100 over 1,000

We confirm your total and mark exactly the required number — no guessing.

Van-Accessible Stall Requirements

At least one of every six accessible spaces (or fraction of six) must be van-accessible. A van-accessible stall needs either a 132-inch-wide space with a 60-inch access aisle, or a 96-inch space with a 96-inch aisle, plus higher signage and 98 inches of vertical clearance along the van’s route. Every lot with accessible parking needs at least one van-accessible stall.

Access Aisle Dimensions

Access aisles are the striped safety zones beside accessible stalls that let a wheelchair or lift deploy. Car-accessible stalls require a 60-inch-wide aisle; van-accessible configurations require a 96-inch aisle (or the wider stall option). Aisles must connect to an accessible route to the building entrance, be marked to discourage parking, and — for two adjacent stalls — can share one aisle between them, all per Section 502.

ISA Symbol & Pavement Marking

Each accessible stall carries the International Symbol of Access — the wheelchair symbol — painted on the pavement in the correct blue and proportions, plus the access-aisle hatching. We stencil clean, correctly sized symbols so they read clearly and hold up. Faded or misshapen symbols are a common compliance flag, so symbol quality matters as much as placement.

Required Signage

Every accessible space needs a sign displaying the ISA symbol, mounted so the bottom of the sign is at least 60 inches above the ground and located so a parked vehicle can’t hide it. Van-accessible stalls add a “Van Accessible” designation. Signs follow the 2010 ADA Standards and the MUTCD R7-8 series; we can install the posts and signs along with the pavement markings so the stall is compliant top to bottom.

Slope & Surface Rules

Accessible stalls and aisles must be nearly level — no steeper than 1:48 (about 2%) in any direction, per Section 502.4 — so a wheelchair doesn’t roll and a lift deploys safely. Striping can’t fix a slope that’s out of tolerance, but we measure it and flag it, because a properly marked stall on too-steep pavement still fails. Surfaces also need to be firm, stable, and slip-resistant.

Common ADA Violations We Fix

The violations we see most often are faded stalls and symbols, access aisles that have been striped too narrow or left off entirely, missing or too-low signage, no van-accessible space, and accessible stalls placed off the shortest accessible route to the door. Each one is correctable. We audit the lot against the 2010 Standards and bring the whole accessible-parking system back into compliance in one visit.

Idaho Enforcement

Beyond the federal ADA, Idaho enforces accessibility through the International Building Code, Chapter 11, which the state adopts and which references the ICC A117.1 standard for the technical criteria — the same stall, aisle, and signage geometry. Practically, that means an accessible lot in Boise is checked against both the federal 2010 ADA Standards and the state-adopted IBC/A117.1 requirements. We build to both so the lot passes either review.

Our ADA Striping Process

We keep ADA work methodical so nothing gets missed:

1. Audit the lot against the 2010 ADA Standards — total stall count, existing accessible spaces, aisle widths, slopes, and signage.
2. Calculate the required number of accessible and van-accessible stalls for your total count.
3. Lay out accessible stalls on the shortest accessible route to the entrance, at correct stall and aisle widths.
4. Mark and stencil stalls, access aisles, and the International Symbol of Access in the correct blue and proportions.
5. Install signage at the required height and verify the whole accessible-parking system against the Standards before we leave.

Commercial Properties We Serve

We stripe ADA parking for retail centers, medical and office buildings, restaurants, HOAs and apartment communities, schools and churches, and government sites across the Treasure Valley. Any commercial lot open to the public needs compliant accessible parking, and we make sure yours has it.
