Large storage units can provide the extra room needed during a household move, military transition, renovation, downsizing project, or major home reorganization. At SecureSpace Self Storage Mililani, available large-unit sizes include 10x15, 10x20, 10x25, and 10x30.
The facility on Wikao Street also offers drive-up and climate-controlled options, month-to-month leases, online rentals, carts and dollies, and daily gate access from 6:00 AM to 10:00 PM.
This guide explains how large storage units differ, what may fit inside them, and which features to consider before renting.
Located in Central Oahu, Mililani includes Mililani Town and Mililani Mauka, which together are home to approximately 49,000 residents.
Residents may need additional room when:
Moving between homes
Clearing several rooms for renovations
Combining households
Preparing a property for sale
Coordinating a military PCS move
Downsizing gradually
Organizing recreational equipment
Storing permitted business inventory
Making room for additional family members
Many homes and condominiums offer limited built-in storage. A larger unit can provide supplemental space without requiring every belonging to remain in a garage, closet, spare room, or temporary container.
Mililani serves households near Wheeler Army Airfield and Schofield Barracks. U.S. Census Bureau data reports 2,826 veterans in Mililani Town for the 2020-2024 period, reflecting the community's connection to military life.
Permanent Change of Station moves may involve several overlapping schedules:
Household-goods shipping
Temporary lodging
Housing availability
Vehicle transportation
Reporting dates
Delivery appointments
Move-in inspections
Information about base housing at Schofield Barracks can help military households understand local housing options before arrival.
The Army's relocation guide explains that the Joint Personal Property Shipping Office at Joint Base Pearl Harbor-Hickam handles the processing of temporary storage and household-goods delivery after belongings arrive on the island.
When housing and shipment dates do not align, a 10x20 or 10x30 storage unit may provide temporary space for furniture, boxes, appliances, and other household belongings.
Service members should confirm storage authorization, reimbursement requirements, weight allowances, and delivery procedures with the appropriate transportation or housing office.
When parents, adult children, grandparents, or other relatives combine households, several sets of belongings may need to fit within one home.
A larger storage unit can help organize:
Duplicate furniture
Extra appliances
Seasonal decorations
Recreational equipment
Family keepsakes
Clothing
Moving boxes
Household supplies
Separating belongings by household member or room can also make it easier to retrieve items without unpacking the entire unit.
The best unit size depends on the dimensions and quantity of the belongings, how they can be arranged, and how much aisle space is needed.
A 10x15 provides approximately 150 square feet of floor space.
It may be considered for:
Furniture from several rooms
Mattresses and bed frames
Sofas and chairs
Dining furniture
Appliances
Moving boxes
Office furniture
Seasonal household belongings
This size may work well for a partial household move, renovation, or larger decluttering project.
A 10x20 provides approximately 200 square feet of floor space.
Possible uses include:
A multibedroom household move
Several large appliances
Living-room and dining-room furniture
Bedroom sets
Boxes and storage bins
Renovation supplies
Permitted business inventory
Eligible indoor vehicle storage
Indoor vehicle storage depends on vehicle dimensions, drive-up availability, documentation, and facility rules.
A 10x25 provides approximately 250 square feet, while a 10x30 provides approximately 300 square feet.
These sizes may help with:
Large household moves
Whole-home renovations
Combining two households
Furniture from several bedrooms
Major appliances
Substantial quantities of boxes
Office furniture
Permitted business inventory
Eligible indoor vehicle storage
Capacity varies based on item dimensions, furniture disassembly, stacking, doorway clearance, shelving, and aisle space.

Storage-size estimates are useful for planning, but they are not guarantees.
Before selecting a unit, measure:
Sofas and sectionals

Desks
Shelving
Recreational equipment

Disassembling furniture can save space, but keep hardware in labeled bags and attach each bag securely to the corresponding item.
