7 Best Private Property Signs for HOAs and Apartments

The best private property signs for 2026 are 0.080 inch aluminum panels with ASTM D4956 Type III sheeting and tow-warning legends that satisfy Oregon ORS 98.812. Posting density requires signs at every entrance and at intervals visible from any stall. Below are seven ranked spec picks for HOA, apartment, retail, and office-park property managers in Oregon.

What Makes a Private Property Sign "Best"?

Five criteria separate enforceable private-property signage from advisory signs that tow contractors will not act on:

• ORS 98.812 wording -- the legend (or a paired addendum) must include notice that vehicles will be towed, the tow contractor's phone number, and posting at entrances.
• Substrate -- 0.080 inch aluminum minimum.
• Sheeting grade -- ASTM D4956 Type III for night visibility under headlamps.
• Mount height -- 4 to 7 feet to bottom of sign on private property.
• Posting density -- every entrance, every 50 feet of perimeter, visible from every stall.

Tow enforcement worked from the day signs were posted.

How Does ORS 98.812 Tow Authority Work?

Oregon ORS 98.812 authorizes private-property towing only when the property is signed correctly. The statute requires:

• The sign legend (or paired addendum) to include notice that vehicles parked in violation will be towed at the owner's expense
• The phone number of the tow contractor performing the removal
• Posting at every property entrance and at intervals visible from any stall

A sign without the tow contractor's phone number does not satisfy the statute, regardless of how clearly it warns about violations. A property without signs at every entrance does not satisfy the statute, regardless of how compliant the individual signs are.

The Oregon Department of Justice has published consumer-facing materials on private-property towing rights. Property managers should keep their tow-contract paperwork and signage spec on file in case of dispute.

Industry Baseline Range

Current Market Reality

Multi-stall numbered Reserved batches for apartment properties are the cost-efficient way to handle re-sign jobs in 2026. A 30-stall numbered run from a single artwork file runs roughly 25 to 40 percent cheaper per panel than ordering each sign separately. The tow contractor's phone number on every addendum can be updated by panel-replacement when the contractor changes -- the rest of the panel stays in service.

Practical Recommendation

For Oregon apartment and HOA property managers, the working spec is #1 (Tenant Parking Only with ORS addendum) at every property entrance plus #6 (Numbered Reserved Tenant) per assigned stall plus #4 (Visitor Parking with Time Limit) at the leasing office row. All three on 0.080 inch aluminum with ASTM D4956 Type III sheeting. Verify the tow contractor's phone number on every addendum and reorder when the contractor changes.
