Leasing industrial space is one of the biggest operational decisions a business will make — and one of the easiest to get wrong on paper. A building can look like a great deal per square foot and still cost you months of downtime, surprise upgrades, or lost production once you move in. In the Inland Empire, where warehouse, manufacturing, food production, and logistics demand keeps pressure on the market, business owners need to look past the rate and evaluate whether a property can actually run their operation.
Here’s what I tell every client to check before they sign an industrial lease.
1. Confirm Power Capacity Before Anything Else
The single most overlooked item in industrial leasing is electrical capacity. Two buildings can be identical in size and one can power your equipment while the other can’t. Before you fall in love with a space, find out the available amperage, voltage, and panel capacity, and compare it against what your machinery, refrigeration, or production line actually draws.
Upgrading service from the utility can take months and cost five or six figures — and that timeline is rarely the landlord’s problem unless you negotiate it into the lease. Power capacity should be a go/no-go question, not an afterthought.
2. Verify Zoning and Permitted Use
Just because a building is “industrial” doesn’t mean it’s approved for your industrial use. Food production, manufacturing, and certain logistics operations carry zoning, fire, and health requirements that a standard warehouse may not meet. Confirm the property’s zoning designation with the city, and verify that your specific use is permitted — or whether it requires a conditional use permit.
In cities like Rancho Cucamonga and across San Bernardino and Riverside Counties, getting a use approved can involve permitting timelines that affect your move-in date. Knowing this upfront protects you from signing a lease on a building you legally can’t operate from.
3. Understand What a Triple-Net (NNN) Lease Really Costs
Most industrial leases are triple-net (NNN), meaning you pay the base rent plus property taxes, insurance, and common area maintenance on top. The quoted rate is rarely your real number. Ask for the current NNN estimate, review the operating expense history, and understand how those charges can increase year over year.
For a growing operation, the difference between a quoted base rate and the fully-loaded cost can change which building actually fits your budget. Read the cost structure the way you’d read the income statement on a property you were buying.
4. Match the Building to How You Operate
Square footage is only part of the story. Clear height, column spacing, truck court depth, dock doors, drive-in access, and floor load capacity determine whether your layout and equipment will actually flow. A logistics user needs dock positions and trailer turning radius. A manufacturer needs ceiling height and floor strength. A food user needs drainage, ventilation, and wash-down-ready surfaces.
Walk the building with your operation in mind, not just your headcount. The goal is a property that’s functional for production — not just a good deal on paper.
5. Build in Time for Permitting and Tenant Improvements
If your move requires any build-out — new walls, added power, racking, refrigeration, or a change in occupancy — you’re on a permitting clock the day you sign. Tenant improvement (TI) allowances, who pulls the permits, and how long the city takes all affect when you can actually open the doors.
Negotiate a realistic timeline, clarify what the landlord delivers versus what you’re responsible for, and don’t let rent start before the space is usable. Permitting delays are one of the most common and avoidable causes of early-lease stress.
6. Negotiate Lease Terms That Protect a Growing Business
Beyond rate and term, the clauses that matter most are the ones owners skim past: renewal options, expansion or right-of-first-refusal on adjacent space, assignment and subletting rights, and exit flexibility. If your business is expanding, relocating, or upgrading, your lease should give you room to grow or pivot without penalty.
A well-structured industrial lease is an operational tool, not just a real estate document.
The Bottom Line
The best industrial deal isn’t the cheapest rate — it’s the building that lets your business run efficiently, comply with regulations, and grow without costly surprises. Power, zoning, true occupancy cost, layout, permitting, and lease terms should all be evaluated together, before you commit.
If you’re a business owner, investor, or operator looking at industrial or warehouse space in the Inland Empire, work with someone who thinks about the operation behind the property — not just the listing.
