Question 1

How often should a parking lot be restriped?

Accepted Answer

Thermoplastic lasts 5–7 years; latex paint lasts 2–3 years; epoxy 3–5 years. Restripe when visibility drops below 50%. Annual inspection in daylight and at night determines timing.

Question 2

What is the best striping material?

Accepted Answer

Thermoplastic is the best overall: 5–7 year lifespan at $0.20–$0.35/linear foot with reflective glass beads. More cost-effective than paint despite higher initial cost.

Question 3

What are the ADA requirements for parking lot striping?

Accepted Answer

Per ADAAG: 8-foot spaces with 5-foot aisles (standard) or 8-foot aisles (van-accessible). Diagonal hatching, NO PARKING text, International Symbol of Accessibility stencil, signage at 60 inches minimum.

Question 4

How much does parking lot striping cost?

Accepted Answer

Full-lot thermoplastic: $0.15–$0.25/SF ($7,500–$12,500 for 50,000 SF). Latex paint: $0.08–$0.15/SF. Individual stalls: $3–$5 each. ADA stencils: $25–$40 each.

Question 5

Can restriping increase parking lot capacity?

Accepted Answer

Yes. Professional restriping with layout optimization typically identifies 15–20% additional capacity. At $150/month per space, adding 20 spaces generates $36,000 annually — 800%+ ROI.

Question 6

What colors are required for parking lot markings?

Accepted Answer

White for stalls and crosswalks, yellow for no-parking zones, blue for ADA spaces, red for fire lanes, green for EV charging. Reflective glass beads in all traffic-bearing lines.

Question 7

How do fire lane markings work?

Accepted Answer

Red curbing, 'NO PARKING - FIRE LANE' stenciling every 25–50 feet, minimum 20-foot clear width per International Fire Code. Fines of $100–$500 per violation.

Question 8

What is the striping maintenance lifecycle?

Accepted Answer

Year 1–2: annual inspection, spot repairs. Year 3–4: partial re-mark drive aisles. Year 5–7: full restripe (thermoplastic). Budget $0.05–$0.10/SF annually.
