How Public Storage Pricing Works
Self-storage prices move up or down depending on local demand, availability, and the unit features at each facility. Knowing these factors can help you compare locations and estimate your monthly costs more confidently.
What Affects Monthly Storage Costs
• Unit size: Smaller spaces typically cost less than larger ones, while specialty layouts may influence pricing.
• Features: Climate-controlled units (where available), drive-up access, indoor units, and extended access options may adjust monthly rates.
• Location: San Diego’s coastal neighborhoods, inland suburbs, and high-demand communities can reflect different pricing levels based on space availability.
• Online promotions: Many Public Storage locations offer introductory discounts or reduced first-month pricing.
Typical Public Storage Costs Nationwide
Across the U.S., a common self-storage unit at Public Storage may cost about $31 to $115 per month, depending on size and features. San Diego’s pricing often falls on the higher end of this spectrum due to population growth, limited space in certain neighborhoods, and a competitive housing market.
Common Uses for Storage Units
San Diego residents use storage for a broad range of needs tied to work, school, home life, and seasonal routines.
Business storage
Small businesses, contractors, and independent professionals often choose storage to organize inventory, tools, samples, or supplies without expanding to a larger workspace.
College storage
Students at SDSU, UC San Diego, Point Loma Nazarene University, and other campuses often need storage during summer break, semester transitions, or short-term housing changes.
Moving and reorganizing
Self-storage can make moves, renovations, and reorganizing projects easier by adding extra room to sort, pack, or work on home updates.
Military storage
San Diego’s multiple military installations—including Naval Base San Diego, Marine Corps Air Station Miramar, and Naval Base Coronado—bring frequent relocations and temporary assignments. Storage can help bridge those transitions.
Long-term planning
Some customers choose storage when planning ahead for seasonal items or ongoing household projects. A dedicated off-site space can make long-term organization easier to maintain.
Climate-Controlled Storage Pricing
Climate-controlled units generally cost more than standard indoor spaces and are often selected for longer-term storage or when customers prefer more consistent temperature conditions. National averages for these units range from $114 to $292 per month depending on size, demand, and availability.

Vehicle Storage
Vehicle storage pricing varies by facility and by space type—uncovered, covered, or indoor. National trends place these spaces between $20 and $567 per month, depending on the size and style of parking offered.
Choosing the Right Storage Unit for Your Budget
A few planning steps can help you select the right unit for your needs:
- Take inventory. List boxes, small furniture, recreational gear, or business supplies you plan to store.
- Estimate your size. Use a size guide or estimator to match your list to common storage unit sizes. Many customers appreciate extra space for walking paths or added items.
- Think about how often you’ll visit. A drive-up unit or selecting a location near your daily routes may be helpful if you anticipate frequent visits.
- Consider features. Indoor or climate-controlled units (where available) may be a good fit for items you want to keep in reserve.
- Compare nearby locations. San Diego’s neighborhoods differ in demand and availability, so exploring multiple Public Storage facilities may help you find a rate that aligns with your plans.
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.
