Signing a lease on an industrial unit is one of the more significant commitments a business can make. Too small, and you’re tripping over inventory within a year. Too large, and you’re paying for space that just collects dust. The good news? With a little planning, finding the right size doesn’t have to be a guessing game. At Trico Realty, we’ve helped hundreds of Orange County businesses think through exactly this question — and it almost always starts with the same set of fundamentals.
Start with What You Actually Do
It’s not just about square footage
Industrial space isn’t one-size-fits-all. A distributor moving pallets needs wide-open floor space and dock-high loading. A light manufacturer needs room for equipment, staging, and workflow. A service business might just need a clean, accessible unit with a small office component.
Before you look at a single listing, take a clear-eyed look at your operations:
- What does your daily workflow look like from the moment product or materials arrive to when they leave?
- How many employees work on-site, and what do they need around them to do their jobs well?
- Do you need office space integrated into the unit, or will a mezzanine or separate suite work?
Getting specific about your operations is the fastest path to the right number.
The Math Behind the Square Footage
A simple framework to estimate your space needs
Here’s a starting point many tenants find useful:
- Storage/warehouse operations: Plan for roughly 1,000–1,500 sq ft per employee actively working the floor, plus additional space for your inventory footprint at peak capacity.
- Light manufacturing or production: Equipment footprint + circulation space (roughly 3–4 feet around each machine) + staging area + storage = your baseline. Add 20% for growth buffer.
- Flex/service businesses: Office component (roughly 100–150 sq ft per desk) + operational/shop area + storage.
These are ballpark figures — every business is different. But running through this exercise before you tour spaces puts you in a much stronger position to evaluate what you’re looking at.
The Hidden Cost of Getting It Wrong
Too small costs you money. So does too big.
Going too small is the more obvious mistake — you outgrow your space and face the disruption and cost of an early move or an expensive short-term fix. But going too large has its own costs: higher monthly rent, unused utilities, and space that becomes a psychological drain rather than an asset.
The sweet spot is sizing for where your business realistically will be 18–24 months from now, not just where it is today. If you’re in a growth phase, it’s worth asking your landlord about expansion options, whether that’s adjacent units, flexible lease terms, or right-of-first-refusal on neighboring space.
At Trico, many of our tenants have grown within our parks over the years — which is exactly the kind of long-term relationship we’re built for.
What Else Affects the “Right” Unit?
Size is only one part of the equation
Square footage matters, but so do:
- Clear height: If you’re stacking product, a unit with 18–24 ft clear height gives you vertical storage others don’t.
- Loading configuration: Grade-level vs. dock-high access affects what vehicles can service you and how efficiently.
- Power: Manufacturing and production tenants especially should verify amperage and electrical panel capacity before falling in love with a space.
- Office component: Some units include built-out offices; others are shell. Know what your team needs before you tour.
- Parking: If you have employees or clients on-site regularly, parking ratios matter more than most tenants initially realize.
