Why Every NNN Lease Should Include a PM Program
For property owners and managers, loading docks are among the most expensive areas to repair once a tenant leaves. Heavy truck traffic, forklift impacts, worn dock levelers, and damaged doors all take a toll on your facility’s value. Without a preventive maintenance program, those issues often turn into costly emergency repairs at tenant turnover.

If you own or manage industrial or warehouse property in Boise—or anywhere in the Treasure Valley—you’ve likely seen firsthand how quickly dock repairs add up. By writing loading dock preventive maintenance (PM) into your NNN lease, you can protect your investment, reduce liability, and avoid major repair bills down the road.
How Much Does Loading Dock Damage Cost?
Loading docks are high-impact zones. Here’s what property owners can expect if maintenance is deferred until move-out:
- Dock Door Failures – Preventive maintenance averages only a few hundred dollars per door annually, but emergency replacements can run $5,000–$15,000 per door.
- Dock Leveler Repairs – A single pit-mounted leveler costs $5,000–$10,000 (materials only), plus installation and potential concrete or electrical work.
- Concrete Damage – Severe spalling or pit deterioration can reach tens of thousands of dollars, with some case studies showing six-figure repair costs. Even localized dock damage often costs $15,000–$20,000.
- General Tenant Turnover Costs – Industrial property turnover reports indicate dock and interior fixes can range from $15,000 to over $100,000 depending on tenant use and upkeep.
For comparison, a comprehensive dock preventive maintenance program is a fraction of those costs—and it reduces downtime, improves safety, and extends equipment life.
Why Loading Dock Preventive Maintenance Belongs in Every NNN Lease
Planned maintenance doesn’t just protect your property—it also creates a smoother experience for tenants. When included in the NNN operating expenses, preventive maintenance delivers value for both parties:
- Property Owners – Reduced repair bills, higher asset value, and faster turns between tenants.
- Tenants – Less downtime, safer working conditions, and fewer unexpected equipment failures.
- Risk Reduction – Regular PM helps avoid OSHA violations, liability issues, and workplace injury.
By making dock PM part of your NNN lease agreement, you create predictable costs, ensure accountability, and prevent deferred maintenance headaches.

The ROI of Preventive Maintenance for Loading Docks
A preventive maintenance program is one of the highest-return investments in warehouse property management.
- Small annual PM costs: only a few hundred dollars per door/leveler.
- Big savings potential: avoiding one emergency replacement can save $10,000+ immediately.
- Tenant satisfaction: less disruption to operations, reducing the risk of early lease termination or disputes.
When multiplied across multiple dock positions and over a long-term lease, the savings are substantial.
