Can Wheelchair Ramps Be Installed Over Steps With Railings?

Many older homes in Pasadena and San Diego have front steps with fixed railings. They look classic, but they can be hard to use for people who rely on a wheelchair or have limited mobility. A common fix is to add a wheelchair ramp over or beside the steps and railings. The key question is whether this works for your property.

The good news? You have safe, code-compliant options. You can use a portable ramp for short visits or a modular ramp for daily use. Most setups work without removing the current railings. Your best choice depends on your space, the number of steps, and whether you want a temporary or long-term solution.

This guide covers ADA rules, ramp types, and safety features so you can plan a ramp that fits your home and daily routine.

Key Takeaways:

• A wheelchair ramp over steps with railings is possible. However, it must follow ADA slope and safety requirements to ensure user safety and comfort.
• Options include portable ramps, threshold ramps, and modular systems for long-term use.
• California building codes often require handrails, guard rails, and non-slip surfaces for safety.
• Aluminum wheelchair ramps are durable, weather-resistant, and suitable for both wheelchairs and scooters.

How a wheelchair ramp works over steps with railings

You can place the ramp right over the steps or slightly to one side. The layout depends on your space and local building code. Some homeowners keep the old railings for added safety, but if the ramp has its own handrails or guard rails, you may remove the old ones.

For a single step or short rise, a threshold ramp may be enough. For taller stairs, choose an ADA-compliant system with the right slope. Look for non-slip treads that work well in rain.

California inspectors check handrails and weight ratings. Both are important since scooters and power chairs can exceed 600 pounds, and handrails reduce the risk of falls. If the rise is more than 6 inches, ADA rules require handrails on both sides, extended past the top and bottom landings for safer entry and exit. 

Contractors often recommend aluminum modular ramps since they are durable, weather-resistant, adjustable, and can handle daily use.

ADA guidelines and ramp slope for railings and stairs

If you’re considering adding a wheelchair ramp to your California home, make sure it meets ADA standards. The Americans with Disabilities Act requires a slope ratio of 1:12. For every 1 inch of rise, you need 12 inches of ramp.

For example, a 24-inch staircase would require 24 feet of ramp. That can be longer than your front yard allows. In that case, use an L-shaped or switchback ramp so that the run doubles back and maintains a safe slope.

Ramp types that work with existing staircases

Stair layouts vary, but several ramp options can work even when railings are in place. 

Some wheelchair ramp options you can consider include:

• Portable wheelchair ramps: Good for travel or short-term use. Brands like EZ-ACCESS sell lightweight single-fold models. Best suited for one or two steps, rather than a full staircase.
• Threshold ramps: Small ramps for doorways or a single step. They are often made of aluminum or rubber, making them affordable and easy to move.
• Modular ramps: Semi-permanent systems that can go over existing steps. They usually include handrails, guard rails, and heavy-duty parts for long-term use.
• Vertical platform lifts: If space is tight, a lift may work better than a long ADA ramp.

Some factors can influence ramp pricing. Portable ramps are relatively affordable, costing only a few hundred dollars. Modular ramp systems for multiple steps or long slopes may run into the thousands.

Safety features to consider when installing a ramp over railings

Safety should be the top priority when adding a wheelchair ramp. Look for ramps with:

• Non-slip surfaces to handle rain or coastal fog
• Proper handrails and guard rails for balance
• Verified weight capacity for both manual wheelchairs and scooters
• Heavy-duty aluminum wheelchair ramps for long-term durability

If you plan a DIY job, check local code before you start. Shortcuts can be risky. A ramp that is too steep or missing railings can cause falls.
