Speed Bumps for HOA Communities: 2026 Approval & Install Guide

An HOA speed bump is a rubber, asphalt, or concrete unit installed on a private road inside a planned community, governed by the HOA's CC&Rs and Oregon's planned-community law. Before install you need board approval, member notification, and fire-marshal coordination. Oregon Revised Statutes Chapter 94 gives planned-community boards the authority to make and enforce traffic-calming decisions on private community roads, but the process has to be documented and the bump cannot block emergency vehicles.

Below: the approval steps, the product picks that work best for HOAs, the fire-access constraint, and a Beaverton HOA install we ran. Commercial parking-lot installs are different — see What Are Speed Bumps? Complete 2026 Buyer's Guide.

Why do HOA boards install speed bumps?

A typical HOA board commissions a speed bump for one of four reasons:

1. A child or pet was struck or nearly struck by a speeding vehicle in the community
2. Repeated complaints at quarterly board meetings about a specific street or curve
3. A traffic study -- often commissioned for a different reason like a re-paving project -- showed 85th-percentile speeds above 20 mph on a community street posted at 15 mph
4. An insurance carrier asked the HOA to demonstrate active traffic-calming as a condition of premium discount or renewal

The Federal Highway Administration Traffic Calming ePrimer reports that vertical-deflection devices reduce 85th-percentile speeds by 22 to 40 percent on private community streets, more than any other traffic-calming measure that does not require permanent road reconstruction.

What is the HOA approval process for a speed bump?

Five steps cover most Oregon HOAs:

1. Verify the CC&Rs allow it

Read the community's Declaration of Covenants, Conditions, and Restrictions for any clause that addresses traffic-calming, speed bumps, or modifications to the common-area roads. Most CC&Rs delegate authority to the board, but a few older communities require a member vote at an annual meeting. ORS 94.640 governs the procedural requirements.

2. Notify members

ORS 94.640(2) requires the board to provide notice of any decision affecting common areas. A typical notice: 30 to 45 days before the planned install, including:

• Product photo and dimensions
• Install location with a sketch or aerial photo
• Marking plan (yellow-and-black chevron, advance signage)
• Cost to the association and per-household allocation
• Open comment window with a written-response deadline

A 30-day notice with a 14-day comment window is the most common configuration in Oregon HOAs Cojo has worked with.

3. Coordinate with the fire marshal

Per International Fire Code Section 503.2.5 and NFPA 1141, fire-apparatus access roads must remain unobstructed. Fire marshals in Oregon (Tualatin Valley Fire & Rescue, Portland Fire & Rescue, Lake Oswego Fire) require coordination if any bump is installed on a designated fire-access road. The most common outcome: the marshal approves a speed cushion (with wheel-track gaps for fire trucks) instead of a solid bump on the fire-access roads, and approves solid bumps on the non-fire-access streets.

4. Hold the board vote

The board votes at a meeting with quorum, the result is recorded in the minutes, and the minutes are made available to members per ORS 94.640(7). Voting is typically by simple majority unless the CC&Rs specify supermajority for road modifications.

5. Schedule the install

After board approval and member-notice expiration, the install is scheduled. Cojo's standard practice on HOA installs: a 7-day install-window notice in addition to the original ORS 94 notice, with door-hangers on every directly-affected unit two days before crew mobilization.

What products work best in an HOA?

Three product categories cover most HOA needs:

1. Recycled rubber (most-installed in Oregon HOAs)

Modular 6-foot or 8-foot sections, 3 inches tall, anchor to existing asphalt with concrete or asphalt anchor hardware. Cost: $300 to $900 per section installed. Removable for re-paving, snow-removal, or community repaint events. The product Cojo recommends for first-time HOA installs.

2. Asphalt (cast-in-place)

Permanent, integrated with the road surface, no anchor hardware to inspect. Cost: $400 to $1,500 per bump installed. Best for HOAs that have just completed a re-paving project and want the bump to read as part of the new road, not as an aftermarket addition. Lifespan: 7 to 10 years.

3. Speed cushion (where fire-access requires it)

Modular cushion with wheel-track gaps, 6-foot total width, 3 inches tall. Cost: $2,000 to $5,000 per cushion installed. Required by Oregon fire marshals on designated fire-access roads. Cushions also generate fewer complaints from residents who drive larger pickup trucks because the wheel-track gap means at least some vehicles can ride through with one wheel in the gap.

Where should HOA speed bumps go?

Six locations cover most HOA layouts:

Location	Reason
Just inside the main entrance	Sets the tone for the community speed
Before a curve with limited sight distance	Prevents over-speed on blind sections
Near the community pool, playground, or clubhouse	Pedestrian-vehicle conflict zone
Where a community road tees into a major arterial	Slows exiting traffic to a safer merge speed
On long straight runs over 500 ft	Prevents acceleration to highway speed
Within 100 ft of a marked pedestrian crossing	Reinforces the crossing's right-of-way

The most common HOA mistake is installing too few bumps. A community with bumps only at the entrance and exit produces a "bump-and-accelerate" pattern: residents slow at the bumps and re-accelerate to over-speed in between. According to ITE Traffic Calming Manual research, optimum bump spacing on private community streets is 150 to 250 feet apart, not 800 feet apart.

Real install: Cojo at a Beaverton HOA

In August 2025, Cojo installed four rubber speed bumps in a 32-unit Beaverton HOA. The community had two playground-adjacent near-miss incidents in the prior 12 months and an insurance carrier had asked for engineered traffic-calming as a renewal condition.

Specification:

• Four 8-foot recycled-rubber bumps, 3 inches tall
• Yellow-and-black chevron pre-molded
• Reflective tape on each bump end
• MUTCD W17-1 "Bump" signs at 100 feet upstream of each bump
• Locations: just inside the gate, before a blind curve, adjacent to the playground entrance, before the rear-exit gate
• Total install time: 8 crew-hours
• HOA process: ORS 94.640 notice issued July 1; member comment window closed July 15; board vote July 22; install August 14
• Tualatin Valley Fire & Rescue coordination: the rear-exit-gate bump location was changed from a solid bump to a speed cushion to satisfy TVFR fire-access requirements

The HOA board reported that the post-install community survey showed 86 percent of responding residents felt the community was safer, and the insurance carrier renewed at a 4 percent premium discount.

What does it cost an HOA to install speed bumps?

Industry Baseline Range for HOA speed-bump installation:

Item	Industry Baseline Range
Rubber bump (6 to 8 ft, installed)	$300 to $900+
Asphalt bump (cast-in-place, installed)	$400 to $1,500+
Speed cushion (fire-access compliant)	$2,000 to $5,000+
MUTCD signage per bump	$150 to $400
ORS 94 notice production and mailing	$250 to $700
Fire-marshal coordination fee (where applicable)	$150 to $500

These figures reflect published industry averages. Current market pricing varies significantly and actual quotes may fall well outside these ranges based on site-specific conditions, material costs, and project complexity.

Current Market Reality

2026 HOA install pricing reflects elevated rubber-feedstock costs, prevailing-wage requirements on community-road work above $25,000, and added documentation expectations from HOA legal counsel since the 2024 update of Oregon planned-community statutes.
