An Ontario warehouse quote is not always the amount your business will pay each month. Traditional industrial leases may separate the base occupancy charge from property taxes, insurance, common-area maintenance, utilities, internet, equipment, and setup.

That matters when you need a few hundred or a few thousand square feet rather than a full distribution building. Compare the complete commitment, not the first number on a listing.

Start with the lease structure

A triple-net lease, usually written as NNN, passes property taxes, building insurance, and maintenance costs through to the tenant. CAM charges may cover exterior lighting, landscaping, parking areas, security, and other common expenses. Utilities, internet, and repairs can remain separate.

Ask for a written schedule of every recurring charge, the escalation method, and the prior year’s reconciliation. Then confirm the minimum term, deposit, guarantees, renewal options, and early-exit provisions.

Separate market evidence from your quote

The City of Ontario’s 2024 economic-development materials reported more than 120 million square feet of industrial space and a 4.6% industrial vacancy rate. Its May 2026 for-lease report shows active warehouse, light-distribution, and manufacturing listings across the Airport Area submarket.

Those figures describe the broader Ontario industrial market, not small private units and not WareSpace pricing. A building can have available space while still offering nothing close to the size, term, or operating setup your business needs.

Add one-time costs such as racking, material-handling equipment, security, electrical work, internet installation, and deposits. Include the cost of unused square footage, too.

Reduce the risk before signing

Verify permitted use, loading procedures, HVAC coverage, power, parking, insurance, renewal increases, and who pays for repairs. If your business volume changes, the wrong footprint or a long commitment can be more expensive than a higher-looking monthly fee with fewer extras.
