A storage unit is usually the better choice when you want your garage back for your car or a workspace, and a garage is better for things you use every day. At AA Personal Storage in Parowan, Utah, drive-up units start at $40 a month for a 5x10, and a 10x25 unit ($125 a month) has about the same floor space as a one-car garage.
Lots of Iron County homes have a garage that stopped holding cars years ago. It fills up with boxes, camping gear, a spare fridge, and furniture from the last move, and the truck sits outside through another winter. This guide compares a storage unit and a garage side by side, shows which unit sizes match a garage, and explains what you can and can't do with a unit at AA Personal Storage in Parowan, Utah.
It depends on how often you need the stuff. Keep daily-use items in the garage and move seasonal, sentimental, and "someday" items to a storage unit, which frees the garage for parking or projects.
A garage is attached to your home, so it wins on convenience for anything you grab every week: tools, the lawn mower, bikes, the kids' sports gear. A storage unit wins when the garage is so full that it no longer does its main job. Here is how the two compare at a glance.
| Factor | Home garage | Storage unit at AA Personal Storage |
|---|---|---|
| Monthly cost | Already part of your mortgage or rent | $40 to $210 a month for enclosed units, $30 to $40 for outdoor parking |
| Access | Steps from your kitchen | 24 hours a day, 7 days a week, a quick drive from anywhere in Parowan |
| Parking a car | Yes, if you can clear the floor | Not in enclosed units; vehicles go in outdoor parking |
| Contract | None | Month-to-month, no long-term contract |
| Security | Your home and garage door | Digital video surveillance, well lit at night, your own lock |
| Space limits | Fixed size | Choose 50 to 520 square feet and change sizes as needs change |
| Climate | Usually unheated | Not climate controlled |
Neither option is heated or cooled, so the weather question is a wash. The real tradeoff is money and convenience versus getting your garage back.
At AA Personal Storage in Parowan, Utah, enclosed units cost $40 to $210 a month and outdoor parking costs $30 to $40 a month, as listed on our Rent page in November 2026. Your garage has no monthly fee, but you are already paying for that space.
That second point matters. If your home costs a set amount per square foot and 400 square feet of it is a two-car garage stuffed with boxes, you are paying to store things you rarely touch while your vehicles sit outside. A unit moves those items somewhere cheaper per square foot so the expensive space can go back to work.

A 10x25 unit (250 square feet) is close to the floor area of a typical one-car garage, and a 20x25 or 20x26 unit (500 to 520 square feet) is close to a typical two-car garage. Garage sizes vary, so measure yours.
Garages are not built to one standard size. As a rough guide, many one-car garages are around 12 by 20 to 12 by 22 feet, and many two-car garages are around 20 by 20 to 24 by 24 feet. These are approximate, so grab a tape measure before you pick a unit. Use the table below to match what is in your garage to a unit at AA Personal Storage.
| What is in your garage | Approximate share of a garage | Unit to consider |
|---|---|---|
| A few shelves of boxes and holiday decor | One wall | 5x10 ($40) or 5x12.5 ($50) |
| Boxes plus patio furniture, bikes, and a mower | About half of a one-car bay | 10x10 ($65) |
| Furniture from a downsized room plus boxes | Most of a one-car bay | 10x15 ($75) |
| A full one-car garage, floor to ceiling | One full bay | 10x25 ($125) |
| A full two-car garage | Two full bays | 20x25 ($200) or 20x26 ($210) |
Ceiling height helps too. Our units are 9 to 12 feet tall depending on size, and most garage clutter is stacked far lower than that, so a unit often holds more than its floor area suggests. Stack boxes high and use the full height. Our storage unit sizes guide walks through every size, and what fits in a 10x25 storage unit covers the garage-sized unit in detail.
Door width decides what fits through the opening. A 10x10 has an 8 ft 5 in roll-up door, a 10x25 has an 8 ft door, and a 15x20 has an 11 ft 5 in door, the widest we list. A double garage door is much wider than any of our unit doors, so measure large items like a gun safe or sectional before moving day. Most of our units have their own roll-up door and paved drive-up access, so you can back a truck or trailer right up to the opening.
Not for a car. AA Personal Storage in Parowan, Utah does not allow vehicles in enclosed units. Cars, trucks, RVs, boats, trailers, snowmobiles, and ATVs go in our uncovered outdoor parking, which starts at $30 a month.
People search this question for two reasons. Some want to park a car in a unit, and others want a place to work on projects. Here is how each works at our facility.
So the best way to "use a storage unit as a garage" is the reverse: put the boxes and seasonal gear in a unit so the car can go back in your garage at home.
A unit makes sense when your garage is too full to park in, when you are between homes, or when you have seasonal gear you use only a few months a year. A month-to-month rental lets you keep it only as long as you need it.
Common situations we see in Parowan and nearby towns:
A garage is better for things you use every day or every week, for vehicles you drive daily, and for anything you can't legally keep in a unit, such as gasoline or propane.
Keep these at home in the garage:
If the garage can hold all of that and still fit a car, you may not need a unit at all. If it can't, move the least-used items first.
Sort by how often you use each item. Anything you touch weekly stays home, anything you use seasonally or rarely goes to the unit, and anything you haven't used in a year is worth selling or donating first.
A simple three-pile method works well:
Once you know what is going, measure the "move to storage" pile and match it to the size table above. Our guide on drive-up vs. indoor storage explains why ground-level, drive-up units make loading easy, and our month-to-month vs. long-term storage guide helps you plan how long to rent.
