A numbered tenant parking sign assigns a specific stall to a specific tenant unit. Standard spec is a 12-by-18-inch aluminum panel with ASTM D4956 Type IV reflective sheeting, vinyl-cut or digital-printed unit number, mounted at 7 to 8 feet above pavement on a galvanized U-channel or telespar post. HOA and multifamily properties use them to enforce assigned parking; medical and office complexes use them for executive parking and visitor lot management. The mounting height is lower than ADA requirements (60 inches to bottom of panel) because tenant signs are not regulated under ADA Std 502.6 -- but most property owners standardize at 60 inches anyway for visual consistency across the lot.
A numbered tenant parking sign typically reads:
Panel size is most commonly 12 by 18 inches in portrait orientation. 6 by 12 inches works for compact stalls or wall-mount applications.
ASTM B209 0.080-inch-thick aluminum is the parking-lot standard. Aluminum does not rust, takes vinyl and digital print cleanly, and lasts 10-plus years.
ASTM D4956 Type IV high-intensity prismatic is the right pick for assigned-stall signs. Type I engineer-grade saves $15 to $30 per panel but loses readability under low light at 5 to 7 years; Type IV stays readable to 10 to 12 years. The cost-over-time math favors Type IV.
Two production methods:
For simple numbered signs, vinyl-cut is the standard. For HOA or apartment-complex jobs that include tenant logos or color-coded zones, digital print is the right call.
| Post | Cost | Use |
|---|---|---|
| 9-foot 2-inch galvanized U-channel | $35 to $75 | Standard apartment lot, HOA |
| 9-foot 2-inch telespar | $50 to $110 | High-turnover apartment, theft-prone |
| 4-by-4 wood | $25 to $50 | Decorative, rural HOA |
| Aluminum | $80 to $160 | Coastal, salt-air |
Standard 12-inch-diameter by 24-inch-deep concrete footing handles passenger-vehicle bump and snow-plow strikes.
Stainless steel theft-resistant bracket and fasteners. The marginal cost ($15 to $40 per sign) prevents the most common loss case -- tenants or visitors removing the sign with a standard wrench.
| Use Case | Bottom-of-Panel Height |
|---|---|
| Standard tenant sign (no ADA designation) | 60 to 84 inches |
| Wall-mounted (parking garage) | 60 to 72 inches |
| ADA-designated tenant stall | 60 inches minimum per ADA Std 502.6 |
| Executive / visitor sign | 72 to 84 inches (premium visibility) |
Industry Baseline Range
| Component | Cost Range |
|---|---|
| 12 by 18 aluminum panel with Type IV sheeting | $35 to $80 |
| Vinyl-cut number / legend | $5 to $15 per panel |
| Digital-print custom number / legend | $15 to $35 per panel |
| 9-foot galvanized U-channel post | $35 to $75 |
| 9-foot telespar post | $50 to $110 |
| 12 by 24 concrete footing | $25 to $65 |
| Theft-resistant bracket and fasteners | $15 to $40 |
| Crew labor, batched (5-plus signs) | $35 to $90 per sign |
| Total per sign, batched install | $145 to $410 |
| Total per sign, single install | $213 to $620 |
2026 numbered-sign pricing trends 12 to 18% above baseline because of aluminum-panel raw-material price increases and Type IV sheeting cost inflation. Multi-sign batched jobs (15-plus signs at one apartment complex) trend toward the lower end; single-sign emergency replacements price toward the upper end.
Cojo installed a 24-sign numbered-tenant package at a Hillsboro apartment complex in February 2026:
Total project: $4,560 batched. Per-sign average $190. The complex had been losing 4 to 6 sign panels per year to tenant moves and theft on the prior U-channel + zinc-bracket spec; the telespar + theft-resistant package is projected to drop annual replacement cost to under $400.
Some property managers laminate paper unit numbers onto a generic "RESERVED" sign. The paper insert fails in 3 to 6 months under Oregon rain. Vinyl-cut directly on the sheeting holds 8 to 10 years.
Standard hex-bolt brackets get unscrewed by tenants moving out who take their sign with them. Theft-resistant fasteners (security shroud or one-way bolt) prevent this -- the $15 to $40 premium pays back inside 12 months on apartment-complex jobs.
Property managers who install ADA stalls at 60-inch bottom-of-panel and tenant stalls at 72-inch bottom-of-panel create visual inconsistency. Standardize at 60 inches across the lot for cleaner appearance and to keep ADA stalls compliant.
Anchored-only posts (no concrete footing) drift after 6 to 12 months as freeze-thaw works the post out of the asphalt. Concrete footing is non-negotiable -- the $25 to $65 cost is well below the cost of post replacement.
Parking garages and covered lots benefit from wall-mounted numbered signs at the head of each stall. Wall-mount eliminates the post and footing line items and saves $60 to $135 per sign. The mounting height rule is the same -- 60-inch bottom of panel.
ADA Std 307 protruding-object rules apply -- wall-mounted signs at standard bracket projection (under 4 inches from the wall) are compliant.
Cojo installs numbered tenant parking signs across HOA, apartment, medical, and office properties on the I-5 corridor with vinyl-cut or digital-print legends and theft-resistant hardware. Multi-sign installs amortize crew time and trend toward the lower end of the published baseline. Contact Cojo for a numbered tenant sign install quote.
