Quick answer
ADA improvements make parking lots usable for people with disabilities. USA Paving builds and rebuilds parking lot ramps, regrades accessible stalls and access aisles, builds smooth transitions, installs detectable warning surfaces (the bumpy warning pads at ramps) and stripes the accessible stalls, aisles and symbols, for properties across Northern California.
Accessible parking works as a system: a level stall and access aisle, a ramp up to the walkway, a smooth transition where the pavement meets the ramp, a detectable warning surface where a ramp enters a street or drive, and clear striping and symbols. If one piece is off, the whole route can fail an inspection or a complaint.
Accessibility requirements come from the federal ADA Standards and, in California, the state building code, and they depend on the property and the work being done. We build to the plans, survey or inspection report you give us, and we will point out anything in the field that looks like it will not work before we start.
Why choose USA Paving for ADA improvements
- Parking lot curb ramps and ramps rebuilt to the slopes on your plan or survey
- Accessible stalls and access aisles regraded level, then striped with the accessible symbol
- Smooth, flush transitions where pavement meets ramps, walkways and landings
- Detectable warning surfaces (the bumpy tactile pads, also called truncated domes) installed at ramps
- Work phased so entrances and some parking stay open where possible
Signs you need ADA improvements
- You received an accessibility complaint, demand letter or inspection report
- Accessible stalls or access aisles are faded, sloped or hard to reach from the entrance
- Parking lot ramps are cracked, too steep, or have lifted or uneven edges
- Detectable warning surfaces at ramps are missing, worn or damaged
- There is a lip or uneven transition where the pavement meets a ramp or walkway
How the work goes
- 1
Review your plan or report
We walk the site with your accessibility survey, plans or notice, and measure the stalls, aisles, ramps and routes involved.
- 2
Grade and pave
Stalls, aisles and landings are regraded and repaved where needed so they sit level and drain properly.
- 3
Ramps, transitions and warning surfaces
Ramps and transitions are built to the specified slopes, and detectable warning surfaces are installed where the plan calls for them.
- 4
Stripe and mark
Stalls, access aisles and accessible symbols are painted to the layout, and signage locations are coordinated with you.

ADA Improvements FAQs
What are the bumpy strips at curb ramps called?
They are called detectable warning surfaces, also known as truncated domes or tactile warning pads, and people often call them rumble strips or bumpy tiles. They warn people who are blind or have low vision that they are about to enter a street or driving area. We install and replace them as part of ramp work.
Can restriping alone fix my accessible parking?
Sometimes, but not always. If the stall and access aisle are level and laid out correctly, fresh striping and symbols may be enough. If they slope too much or are in the wrong place, the pavement has to be regraded or rebuilt first.
How steep can an accessible parking stall be?
Accessible stalls and their access aisles generally cannot slope more than about 2 percent (1:48) in any direction, and ramps have their own slope limits. That is why they often need grading work. Exact requirements depend on your project and local code.
Do you prepare ADA plans or surveys?
Our work is construction. When a property needs an accessibility survey or plans, a qualified access specialist or design professional prepares them, and we build to those documents.
