Office vs. Flex vs. Light Industrial Space in Utah

A growing company often hits the same fork in the road. The next space could be a traditional office, a flex building with warehouse in back, or a light industrial building with real loading. Pick the wrong type and you pay for space you cannot use, or end up in a building that fights your operation.

This post explains what each type is, how they usually differ on build-out, parking, loading, zoning and lease structure, and ends with a decision table. Every building and every city is different, so confirm the details for any site you are serious about.

The three types in plain terms

Office. Space built for people at desks: open work areas, private offices, conference rooms, break rooms and restrooms, with finished ceilings, plenty of heating and cooling, and lots of parking.

Flex. A hybrid. Usually a single-story building where the front is finished like an office or showroom and the back is open warehouse or shop space, often with grade-level (drive-in) doors. The office share can be small or large, and it can often be changed between tenants. Flex suits companies that need both desks and a place to store, assemble, test or ship.

Light industrial. A building made mostly for making, storing and moving goods, with a small office area. Compared with flex, expect taller clear height (usable height under beams and sprinklers), more dock-high doors for trailers, heavier power and a truck court sized for semi-trailers.

The labels are not standardized. One owner's "flex" is another owner's "light industrial with office." Judge the building by its specs, not its marketing name.

Typical build-out

Office carries the most interior finish per square foot: walls, ceilings, lighting, flooring, restrooms sized for headcount, and zoned heating and cooling. Changing a layout means demolition, so the first plan matters.

Flex splits the build-out. The office or showroom front gets office-style finishes. The back is usually left simpler: exposed ceiling, sealed concrete floor, warehouse lighting and heating. Many companies change the ratio of office to warehouse over time, which is part of the appeal.

Light industrial spends its money on the shell and systems: floor slab, clear height, sprinklers suited to what you store, power, docks and doors. The office area is often modest.

Whatever you choose, remember that interior work is regulated. Utah applies a statewide construction code that adopts the International Building Code by reference, along with state and local amendments, for construction, alteration, remodeling and repair. Turning warehouse space into offices, or an office into a lab or shop, can trigger new requirements for exits, restrooms, fire protection and accessibility. Ask an architect or the city's building department early.

Parking and loading

These two items rule out more buildings than anything else.

• Office needs the most car parking for its size, because nearly every square foot is people. Loading is usually limited to a delivery door or a shared dock.
• Flex needs car parking for the office staff plus room for vans, box trucks and drive-in doors. Check whether delivery trucks can maneuver without blocking parked cars.
• Light industrial needs less car parking per square foot but far more truck space: dock-high doors, trailer parking and a deep enough truck court for a semi to back in.

Count your people at shift change and your trucks on your busiest day, then compare those numbers with the site plan. Cities also set parking requirements by use, which can matter when you change how a building is used. For a full loading and power checklist, see our industrial site checklist.

Zoning: the use has to fit the zone

Zoning decides what you may legally do in a building, and the names vary by city. Here is how one Utah city handles it, for illustration only.

Salt Lake City's code describes its BP Business Park District as a place for "modern offices, light assembly and warehouse development" in a campus-like setting. That district requires principal uses to take place inside entirely enclosed buildings and requires accessory outdoor storage to be screened with a solid fence. Uses allowed there are listed in the city's table of permitted and conditional uses for special purpose districts.

The same code's M-1 Light Manufacturing District is meant for light industrial uses "that produce no appreciable impact on adjacent properties." Its uses are listed in a separate table of permitted and conditional uses for manufacturing districts, and the section sets a general building height limit of 65 feet, with stated exceptions.

What this means for you:

• A zone name is not an answer. Look up your specific use in that city's use table and see whether it is permitted, conditional (needs a public approval process) or not allowed.
• Outdoor storage, hours, noise and hazardous materials often have their own rules.
• Each city writes its own code. Salt Lake City's rules do not apply in West Valley City, Lehi or Tooele. Our Salt Lake County guide and the other county guides list official links to start with.

Ask the planning office for a written answer before you sign.

How lease structures commonly differ

Lease terms vary by owner and by deal, but some patterns are common.

• Office is often quoted on a full service or modified gross basis. The rent includes some or all operating costs, such as property taxes, insurance, maintenance and sometimes utilities and janitorial. Expect a base-year or expense-stop clause that passes through increases.
• Flex and light industrial are often quoted on a triple net (NNN) basis. You pay base rent plus your share of property taxes, insurance and common area maintenance, and often your own utilities.
• Improvements tend to be larger for office, because office needs more finish. Industrial tenants often negotiate for systems work instead, such as power, docks or lighting.

Example: Two hypothetical spaces are quoted at the same base rent. One is full service and one is NNN. The NNN space costs more each month once taxes, insurance and maintenance are added, unless its base rent is lower by at least that amount. Compare total occupancy cost, and ask each owner for operating cost estimates in writing.

A decision table

Questions that usually decide it

1. What share of our people work at desks, and will that change in three years?
2. Do we receive or ship goods, and in what kind of vehicle?
3. Do we need taller storage, special power or ventilation?
4. Will clients visit?

If the answers split, flex often bridges the gap for a few years. For the bigger choice of renting, owning or building, read lease vs. buy vs. build-to-suit.
