How Public Storage Pricing Works
Self-storage pricing shifts depending on location, access type, demand, and the mix of features at each facility. Understanding these factors can help you choose a unit that fits both your monthly budget and your plans.
What Affects Monthly Storage Costs
• Unit size: Smaller units cost less, while larger units or uncommon layouts can affect monthly pricing.
• Features: Climate-controlled units (where available), indoor access, drive-up units, and extended access hours can influence rates.
• Location: Pricing can vary significantly between Seattle’s urban core, surrounding suburbs, and areas throughout Pierce, King, and Kitsap counties.
• Online promotions: Many Public Storage locations offer introductory discounts or reduced first-month pricing.
Typical Public Storage Costs Nationwide
Nationally, the average cost of a self-storage unit at Public Storage ranges from $31 to $115 per month, depending on the size and features of the unit. High-density regions with strong housing demand—like Seattle—often show broader ranges, especially for mid-size and larger units.
Common Uses for Storage Units
Seattle-Tacoma residents use storage for a wide range of purposes tied to work, home life, school, and seasonal needs.
Business storage
Local businesses, tech contractors, and independent tradespeople often rely on storage as a flexible extension of their workspace, organizing tools, supplies, samples, or small inventory.
College storage
With major universities—University of Washington, Seattle University, UW Tacoma, Pacific Lutheran University, and others—students often need storage during the summer, study-abroad periods, or housing transitions.
Moving and reorganizing
Storage can support home projects, reorganizing efforts, or moves across the region, offering a designated space to sort and pack without crowding living areas.
Military storage
Given the presence of Joint Base Lewis–McChord and other military sites throughout the region, storage can help bridge relocations, short-term assignments, or temporary housing timelines.
Long-term planning
Some customers choose storage for items they want to keep in reserve or revisit seasonally. Extra space can help simplify projects that unfold over several months or support long-term organization in compact homes.
Climate-Controlled Storage Pricing
Climate-controlled units typically cost more than standard indoor units and may be chosen for longer-term storage or when customers want more consistent temperature conditions. National averages for these spaces generally range from $114 to $292 per month, depending on size and availability.

Vehicle Storage
Vehicle storage options—uncovered, covered, or indoor—vary by location.
Choosing the Right Storage Unit for Your Budget
A few steps can make it easier to select a unit that aligns with your needs:
- Take inventory. List boxes, small furniture, seasonal items, tools, or business supplies you plan to store.
- Estimate your size. Size guides and estimators can help you match your list to the right unit dimensions. Many customers appreciate a small amount of extra room for walking paths or future items.
- Think about visit frequency. Drive-up units or facilities located near your daily routes may add convenience if you plan to stop by regularly.
- Consider features. Indoor or climate-controlled units (where available) may be a good match for items you want to keep in reserve.
- Compare facilities. Rates vary across the Seattle–Tacoma area, so checking a few nearby Public Storage locations may help you find a rate and layout that suits your routine.
Features and amenities vary by location, facility, and unit. “Climate-controlled” and related terms (such as air-conditioned, heated, or humidistat-equipped) describe storage spaces designed to help maintain more consistent temperature or humidity levels compared to non-climate-controlled units. Public Storage does not guarantee temperature or humidity ranges. Availability, features, and unit types may differ by location, facility, and unit. Please confirm with your facility whether specific climate-controlled features are available on units at that location.
