The Rise of Portable Storage in San Diego

Portable storage has changed the way people in San Diego move, remodel, and create extra space at home or work. Instead of driving back and forth to a storage lot, a container comes to your door so you can load at your own pace.

Big Box Storage is one of the longest-running Portable Storage providers in the region, serving local homes and businesses for more than two decades. For anyone comparing portable storage options, it helps to see how Big Box stacks up against other well-known brands in town.

Using portable storage is simple: you schedule a container, it is dropped at your property, you load it, and then choose to keep it on-site or have it stored at a secure facility. This model works well for moves, downsizing, staging a home, or short-term projects where flexible portable storage is key.

1. Big Box Storage – Best Overall Portable Storage Option

Big Box Storage focuses only on portable storage, which helps keep the process simple and streamlined for San Diego residents. The company delivers its "Big Box" unit to your home or business, lets you load it on your schedule, and then either leaves it on-site or takes it back to a secure indoor facility.

Each Big Box container is about 8 feet long, 5 feet wide, and 7 feet high, which suits common needs like a studio or small apartment, seasonal gear, or inventory for a small business. Customers can order multiple units and are only billed for the number they actually use, which makes the company one of the best for storage rentals San Diego can offer.

Big Box Storage also offers shipping of loaded containers to many metropolitan areas across the United States, making it a flexible choice for longer moves. With local roots, a focus on portable storage, and easy access to items seven days a week at its San Diego facilities, Big Box Storage earns the top spot on this list.

Why Big Box Stands Out

• Containers are brought right to your door, so no truck rental or repeated trips are required.
• Option to keep the unit on-site or store it indoors at a secure facility.
• Transparent pricing where you only pay for the portable storage you actually use.

2. PODS

PODS is a national brand that offers portable moving and storage containers in San Diego and many other cities. The company delivers a container to your driveway, allows ground-level loading, and then can store it at a PODS center or move it to a new address.

PODS offers multiple container sizes, which can be helpful for larger households or multi-room moves. For local customers who want a well-known brand with broad service coverage, PODS is a familiar choice for storage rentals San Diego residents may consider alongside local providers.

3. 1-800-PACK-RAT

1-800-PACK-RAT provides portable storage and moving services in the San Diego area using all-steel containers known for their durability. Like other providers, they deliver the container to your property, you load it, and then choose on-site use, warehouse storage, or transport to another location.

Their containers are designed for both local and long-distance moves, with weather-resistant construction and secure locking systems. This makes 1-800-PACK-RAT appealing for customers focused on robust, heavy-duty portable storage solutions.

4. MI-BOX Mobile Storage

MI-BOX offers mobile storage containers in San Diego with a strong focus on convenience and careful handling through its Level Lift System. This system keeps containers level during loading and transport, reducing the risk of items shifting or being damaged.

MI-BOX provides 8, 16, and 20-foot containers, allowing customers to match the container size to their specific project. The company serves both homeowners and businesses, supporting renovations, seasonal storage, and inventory management with flexible rental terms.

5. UNITS Moving and Portable Storage of San Diego

UNITS Moving and Portable Storage serves San Diego with containers designed for both on-site storage and warehouse storage. Customers can use UNITS for moves, home improvement projects, or temporary space during staging and decluttering.

UNITS offers at least one larger 16-foot container size aimed at typical two-bedroom homes, along with secure, lockable doors and weather-resistant construction. The company also promotes climate-controlled storage at its local facility for items that need more protection.

6. Coronado Mobile Storage

Coronado Mobile Storage is a San Diego area provider focused on portable storage rentals delivered directly to customer locations. The company supplies steel storage containers that can be placed at homes, job sites, or commercial properties for flexible temporary storage.

Their services are often used by contractors, homeowners, and small businesses that need on-site storage during construction, remodeling, or expansion. With a local presence, Coronado Mobile Storage offers an alternative to national brands for practical storage rentals San Diego customers may need.

7. National Construction Rentals – Mobile Storage

National Construction Rentals supplies mobile and portable storage containers in San Diego, primarily serving construction sites, events, and commercial clients. Containers are available in 10, 20, and 40-foot sizes, all built with heavy-duty steel and lock boxes to deter theft.

These containers are often used for tools, materials, and high-value equipment on active job sites. While not always the first choice for a residential move, National's portable storage solutions work well for businesses and large projects that demand rugged, secure units.

8. SW Mobile Storage

SW Mobile Storage offers shipping container rentals and portable offices in the San Diego area. Their inventory includes standard storage containers as well as modified units that can serve as temporary job site offices.

Customers can rent, buy, or customize containers depending on their long-term needs. This makes SW Mobile Storage a better fit for commercial, industrial, or government users who require portable storage with more specialized features.

9. U-Haul U-Box Containers

U-Haul provides U-Box portable storage containers at various locations in San Diego, including its Carmel Mountain facility. Customers can pick up U-Box containers with a trailer, have them delivered, or load them at a U-Haul site.

Once loaded, U-Box containers can be stored at a U-Haul facility or shipped to another city through the U-Haul network. This setup works for renters or students who already rely on U-Haul for moving trucks and want an integrated portable storage option.

10. Traditional Self Storage with Portable-Like Benefits

While not portable storage in the strict sense, some self-storage brands in San Diego offer features that make them part of the broader storage conversation. Facilities such as Public Storage and CubeSmart provide drive-up units, extended access hours, and move-in trucks to streamline the process.

These locations can be useful when customers prefer a fixed storage unit with strong security and do not need a container at their door. However, they still require driving to the facility, which is why many residents now lean toward true portable storage when they want maximum convenience.

San Diego residents and businesses have many choices when it comes to portable storage, from national brands to local specialists. Big Box Storage stands out by focusing on simple, flexible, and customer-friendly portable storage that is tailored to the local market.

When comparing options for portable storage and storage rentals San Diego-wide, Big Box Storage earns the top spot for convenience, value, and local expertise.
