Storage Costs by Market

The three markets below show how prices vary across the Inland West, from a fast-growing desert metro with available peripheral land to a constrained Front Range market where infill supply is tight.

How Much Does a Storage Unit Cost in Las Vegas?

Las Vegas has absorbed sustained population growth, which keeps storage demand steady, while comparatively available land on the metro fringe has allowed supply to expand alongside it. Dry heat rather than humidity is the local climate concern, so climate control is used more selectively than in Gulf Coast markets, mainly for heat-sensitive items such as electronics, candles, vinyl, and cosmetics.

A 10x10 storage unit in Las Vegas averages about $112 per month, with small 5x5 units starting around $46 and large 10x30 units averaging $282 (StorageCafe, July 2026).

How Much Does a Storage Unit Cost in Phoenix?

A 10x10 storage unit in Phoenix averages about $111 per month, making it the most affordable of the three markets across reported unit sizes. Sustained extreme heat drives demand for climate control, but active construction helps manage rates: Phoenix has about 471,800 square feet forecast for delivery in 2026, third-highest among cities tracked by RentCafe, while the city sits at 5.6 square feet of storage per capita, below the 7.0 national benchmark (RentCafe Self Storage, June 2026).

A 5x5 averages about $45 per month, a 10x20 runs about $181, and a 10x30 averages $246 (StorageCafe, July 2026). The Phoenix 10x10 average declined 3.5 percent year over year and sits below the national average of $120.

How Much Does a Storage Unit Cost in Denver?

A 10x10 storage unit in Denver averages about $131 per month, making it the most expensive of the three markets. Front Range population growth has been steady, while infill land in the core is limited, keeping the city at 3.5 square feet per capita. Neighborhood variation is notable, and central Denver rates run higher than outer suburban submarkets.

A 5x5 averages about $49 per month, a 10x20 runs roughly $225, and a 10x30 averages $303 (StorageCafe, July 2026). Renters comparing facilities in the area can browse SmartStop Denver storage locations and all Colorado facilities by area.

Size Guide: What Fits and What It Costs

Renters frequently overestimate the size they need, and renting one size larger than necessary is the most common way people overpay. The table below pairs each size with its approximate footprint and what typically fits inside.

Unit Size	Approx. Sq. Ft.	Typical Contents	Best For
5x5	25 sq. ft.	Boxes, seasonal decor, small furniture, sports equipment	Dorm rooms, seasonal storage
5x10	50 sq. ft.	Mattress set, dresser, boxes, studio furnishings	Studio apartments, single bedroom
10x10	100 sq. ft.	Furniture, appliances, and boxes from a 1-bedroom apartment	1-bedroom moves, renovations
10x15	150 sq. ft.	Large furniture and appliances from a 2-bedroom home	2-bedroom households
10x20	200 sq. ft.	Contents of a 3-bedroom home, or a vehicle where offered	3-bedroom moves, vehicle storage
10x25	250 sq. ft.	Contents of a 4-bedroom home, business inventory, equipment	4-bedroom homes, commercial use
10x30	300 sq. ft.	Full estate contents, multi-room inventory, large equipment	Estates, business overflow

A 5x5 suits a few boxes and seasonal items but fills quickly once furniture is involved. The 10x10 is a common choice for a one-bedroom apartment, while a 10x15 typically fits a two-bedroom home. Selecting the right size upfront is a straightforward way to avoid overpaying. For detailed dimensions and layout tips across all options, see the SmartStop storage unit size guide.

What Drives Storage Prices in Phoenix, Las Vegas, and Denver

Land and Real Estate Costs

Storage rates closely track local land values and available development capacity. Inland metros such as Phoenix and Las Vegas have space on the metro fringe for facility development. Las Vegas has 8.2 square feet of storage per capita, compared to 5.6 in Phoenix and 3.5 in Denver, against a 7.0 national benchmark (RentCafe Self Storage, June 2026).

Climate Control Considerations in the West

In hot West climates, climate-controlled storage protects temperature-sensitive items such as electronics, adhesives, candles, vinyl records, and furniture finishes from high ambient heat. On a 10x10 unit, the price premium for climate control ranges from roughly 4 percent in Las Vegas to 7 percent in Denver and 14 percent in Phoenix (StorageCafe, July 2026).

Seasonality and Moving Cycles

Demand increases through the spring and summer moving season and moderates during fall and winter. For renters looking for optimal pricing, reserving during late fall or winter often provides access to competitive promotions and lower entry rates.

Fees Beyond the Advertised Rate

The advertised monthly rate is rarely the full cost. Common additions include a one-time administrative fee, tenant protection plan requirements, lock purchases at move-in, and applicable local taxes. For a full checklist of questions to ask, see our guide on self storage hidden fees.

Is climate-controlled storage worth it in Phoenix?

Climate-controlled storage in Phoenix typically costs about 14 percent more than a standard unit of the same size (StorageCafe, July 2026). Because summer heat can push temperatures inside uncooled units well above the outside air, climate control is worth considering for electronics, wood furniture, photos, documents, and other heat-sensitive items. It is less necessary for tools, metal shelving, or plastic bins of weather-tolerant goods.

What size unit do I need to store a car in Denver?

A 10x20 storage unit fits most standard sedans and compact cars at facilities that offer enclosed vehicle storage. Larger trucks and SUVs may need a 10x25 or 10x30, depending on vehicle length. Confirm vehicle storage rules, door clearance, and availability with your Denver facility before renting. For more tips, see our car storage solutions guide.
