Self Storage Facilities Near You in Mount Vernon, NY

Snapbox Self Storage sits at 275 Washington Street on Mount Vernon’s South Side, a few blocks from the Bronx line in the 10553 ZIP. Every unit inside the building is climate-controlled, and outside we run a gated lot for cars, work vans, trailers, and small RVs.

Most people in Mount Vernon face two space concerns at once: not enough closet space in a pre-war apartment, and nowhere legal to leave a second vehicle overnight. You can solve both at one address instead of driving to Yonkers for one and Pelham for the other.

Rentals are month-to-month with no deposit, and you can reserve a unit online without stopping into the office.

Why Climate Control Matters in a Mount Vernon Building

If you’ve lived in Mount Vernon for a winter and a summer, you already know the problem. The housing stock here is old. Two-family homes on the South Side and walk-ups off Sandford Boulevard were built with damp fieldstone basements, unheated back porches, and attics that hit 110 degrees in August. Most of these buildings have no dry, temperate space to store your belongings not being used.

A climate-controlled unit stays in a steady temperature and humidity range year-round. In practice, that means:

• Wood furniture doesn’t deteriorate. Dressers, dining tables, and bed frames warp and split when they swing between a humid August and a freezing February. Glued joints let go.
• Fabric doesn’t mildew. Mattresses, couch cushions, winter coats, and rugs pull moisture out of damp air and hold it. A basement in Mount Vernon after a heavy rain is exactly the wrong place for a stored mattress.
• Electronics continue to function as expected after you are done storing them. Condensation on circuit boards is what kills stored TVs, computers, and speakers, not the cold itself.
• Paper and photos don’t warp and fade. Business records, tax files, family albums, and artwork curl and fade in an environment with fluctuating temperatures and humidity.

Our rule of thumb: if you’d keep it inside your apartment, it belongs in a climate-controlled unit, not a garage or a container in a lot.

All of our indoor storage units are climate-controlled. There’s no upcharge tier and no gamble about which hallway you land in. Learn more on our climate-controlled storage page.

Outdoor Vehicle Parking in Mount Vernon, NY

Street parking on the South Side is a running battle. Alternate-side rules for street cleaning, permit blocks, snowstorms that require every car on the street to move, and buildings that were built before families owned multiple cars. If you’ve been rotating a second vehicle around the block twice a week, you know the cost in time and parking tickets.

Our gated lot gives you a fixed spot behind a controlled gate with video monitoring, and you come and go on your own schedule.

Who uses it:

• Second cars and weekend drivers. Vehicles you don’t need Monday through Friday shouldn’t be eating a street space or racking up sweeper tickets.
• Contractors and trades. Plumbers, electricians, landscapers, and HVAC crews working across southern Westchester and the North Bronx park work vans and trucks here overnight. Tools stay in the van, the van stays behind a gate, and you roll out to the job in the morning without hunting for where you left it.
• Trailers and small RVs. Landscaping trailers, utility trailers, and small campers that HOAs and landlords have rules around storing near your home.

Parking spaces are month-to-month too, so seasonal contractors can size up in spring and out in winter. Details and current availability are on the vehicle and RV parking page.
