The Hidden Costs of Proprietary Elevator Equipment—and Why KDA Recommends Going Non-Proprietary

When installing or modernizing an elevator system, one of the most critical decisions a building owner can make is whether to use proprietary or non-proprietary equipment. While proprietary systems may seem appealing upfront—often with sleek designs and bundled service offers—they can create long-term challenges that limit your flexibility, increase costs, and restrict your options.

At KDA Elevator Consultants, we strongly recommend that building owners and managers choose non-proprietary elevator systems. Here’s why.

What Is Proprietary Elevator Equipment?

Proprietary elevator systems use parts, software, and diagnostic tools that are exclusive to a specific manufacturer. Only authorized technicians from that manufacturer (or their approved agents) can access system programming, diagnostics, and certain repairs.

Examples of proprietary systems include:

  • Controllers that require specialized tools or passwords to access
  • Software that only the manufacturer can update or troubleshoot
  • Custom parts that are not available through independent suppliers

Implications of Installing Proprietary Systems

1. Limited Service Provider Options
Once proprietary equipment is installed, you’re often locked into using the original manufacturer for maintenance, repairs, and software updates. This eliminates competition—and your ability to negotiate better pricing or switch providers.

2. Higher Long-Term Costs
Monopoly service arrangements can drive up labor and repair costs. You’re often forced to use the manufacturer’s parts, which are priced higher than third-party equivalents and not always readily available.

3. Delayed Repairs and Downtime
Proprietary parts may need to be shipped from a central location or manufacturer warehouse. Combined with a lack of third-party support, this can extend elevator downtime.

4. Difficult Modernizations and Upgrades
Upgrading a proprietary system often requires a full rip-and-replace—because the components are not compatible with other systems. That means higher capital costs down the road.

5. Reduced Building Value and Flexibility
Future buyers or tenants may see proprietary elevators as a liability. It limits their ability to manage the system on their terms, which can affect building value and attractiveness.

Why KDA Recommends Non-Proprietary Equipment

Non-proprietary systems use open architecture, widely available parts, and standard diagnostic tools. This offers many benefits:

✅ Freedom to Choose Your Maintenance Provider
✅ Greater Pricing Transparency and Negotiation Power
✅ More Readily Available Parts and Support
✅ Easier Future Upgrades and Modernizations
✅ Better Long-Term Value for Building Owners

At KDA Elevator Consultants, we work with trusted manufacturers and vendors who offer reliable, code-compliant non-proprietary systems. We help ensure your elevator installation or modernization project supports your long-term interests—not just the vendor’s.

Before You Install, Consult with a Neutral Expert

Many building owners don’t realize they’re locking themselves into a proprietary system until it’s too late. A third-party consultant can:

  • Review equipment proposals before you commit
  • Identify proprietary red flags
  • Recommend open-system alternatives
  • Protect your budget and future flexibility

Choose Equipment That Works for You—Not Just the Vendor

When it comes to elevators, proprietary systems can cost you more than you think. Whether you’re building new, modernizing, or replacing outdated equipment, insist on non-proprietary solutions.
