Parking lot striping in Slabtown is mostly new-construction work on the post-Conway redevelopment mid-rise lots along NW Vaughn and the NW 21st-23rd extensions, plus restripes of converted-industrial lots that are now retail or mixed-use. The buyer is usually a property manager for a new mid-rise building or a tenant-improvement contractor finishing out a ground-floor retail spot. The pricing question is rarely simple per-linear-foot -- it is "new-construction spec layout or restripe of an existing lot, and what ADA, EV, and freight bay markings need to land in the layout." This guide breaks down what Slabtown striping runs and how to vet a bidder.
Why Slabtown Is Different
Three things separate Slabtown from a standard Portland striping job. First, the building stock is mostly post-2015 mid-rise construction with new at-grade retail lots that have never been striped before. New-construction spec layouts run different from restripes because you start from a blank slab and build the layout against the tenant mix -- residential drop-off, retail loading, ADA-accessible routes, EV charger stalls -- rather than restriping an existing pattern. The bid math is different and so is the labor mix.
Second, the converted-industrial restripes. Several blocks of Slabtown still hold former warehouse and light-industrial buildings that have been converted to creative-office or retail. The existing striping on those lots is often 1980s-era industrial-yard markings -- wide forklift travel paths, oversized truck staging zones -- that need a full layout redesign rather than a clean restripe over the existing pattern. Third, freight loading. Slabtown sits on the freight-corridor edge with NW Vaughn carrying significant truck traffic, and any retail lot near the corridor needs loading-dock and freight-bay markings designed against actual delivery patterns.
New-Construction Spec Layout Work
New mid-rise lots in Slabtown come to us with the engineered site plan in hand -- ADA stall counts pre-scaled, EV charger stalls pre-located, accessible routes pre-mapped. Our job is to translate that site plan into painted lines that match the engineer's spec and pass the city sign-off inspection. The work splits into striping installation (linear footage of paint), stall-symbol painting (ADA, EV, electric vehicle reserved, no-parking zones), and signage coordination if the lot scope includes wall-mounted signs.
Spec-layout work runs at a different price point than a simple restripe because the prep is heavier. New asphalt cures for 30 days before striping -- traffic paint will not bond to fresh hot-mix surface oils for the first month. We stripe new lots on day 30 to 45 after the pour. Thermoplastic on new lots can go down sooner because of how it heat-bonds, but most Slabtown new lots run paint at the start and upgrade to thermo at the first restripe cycle. For more on the post-paving stripe cycle, see commercial striping in Portland.
Converted-Industrial Lot Restripes
Restripes of converted-industrial Slabtown lots are bigger jobs than they look. The existing pattern is usually 1980s-era industrial yard layout with stalls that do not match current retail or office demand. A clean restripe over the old pattern would lock in the wrong layout. The correct play is a full layout redesign -- new ADA stalls scaled to the converted tenant mix, EV stalls added per current code expectations, accessible routes mapped to the new building entries, and the old industrial markings burned off or blacked out first.
That black-out step matters. Old paint that gets striped over will bleed through within 12 to 18 months and the new layout becomes visually confusing for drivers. We use a sealcoat black-out on the old pattern before the new lines go down, which adds material and labor but produces a clean layout that lasts.

Industry Cost Picture for Slabtown Striping
Slabtown striping runs at the upper end of Portland ranges because of the new-construction spec work and the full-redesign load on converted-industrial restripes.
Industry Baseline Range
| Project Type | Cost Per Stall | Typical Total |
|---|---|---|
| New-construction lot, spec-layout paint | $14 to $26 | $4,500 to $18,000 |
| Converted-industrial restripe with black-out | $18 to $32 | $6,000 to $20,000+ |
| Standard surface-lot restripe | $4 to $8 | $1,500 to $4,500 |
| EV-stall retrofit (per stall) | $300 to $700 | — |
| Thermoplastic restripe | $14 to $28 | $5,000 to $18,000 |
Current Market Reality
Slabtown striping runs above baseline because of three real costs. First, new-construction spec work involves coordination time with the civil engineer and the city inspector that does not show up on a typical restripe. Second, full-layout redesigns on converted-industrial lots add black-out material costs and 25 to 40 percent more labor than a clean restripe. Third, EV-charger striping retrofits are running at a high rate in this neighborhood because most new buildings are adding L2 charger pairs at completion. For broader pricing context, see our parking lot striping in Portland guide.
ADA, EV, and Freight Bay Markings
ADA stall scaling on new Slabtown lots runs per the 2010 ADA Standards -- 4 percent accessible stalls up to 100 total, with van-accessible width on 1 of every 6 accessible stalls. New construction sites pre-scale this in the civil drawings; converted lots have to be reconfigured to match. EV charger stalls are getting standard treatment now -- painted EV symbol, dedicated stall border, and reserved signage. ADA-accessible EV stalls add another layer because they need van-accessible width plus charger reach.
Freight bay markings on the NW Vaughn corridor lots are unique to this neighborhood. Loading zones need wide-radius truck travel paths, dedicated truck staging stalls (typically 12 feet wide by 60 feet long), and clear separation from passenger-car stalls. A bidder who has not done freight-bay work in this corridor is going to miss the loading-pattern math. Our Pearl District striping crew handles overlapping freight-zone work on Pearl jobs and the same crew runs Slabtown.
How To Vet a Slabtown Striping Bidder
Three questions for any Slabtown bidder. First, on new-construction lots, do you wait the full 30-day asphalt cure before painting, and how do you coordinate with the civil engineer's site plan. Second, on converted-industrial restripes, what is your black-out procedure for the old industrial markings and what does that add to the bid. Third, on freight-corridor lots along NW Vaughn, what is your loading-pattern design experience and can you walk me through a recent freight-bay layout.
A bidder who answers all three cleanly knows the neighborhood. Cojo runs Slabtown striping as integrated commercial scope and coordinates with asphalt maintenance on the long-term cycle so the lot does not slide.
