Understanding the California DSA Portable Classroom

At the heart of California’s educational infrastructure lies the typical Division of the State Architect (DSA) classroom. Measuring 24 feet by 40 feet, these classrooms offer a generous 960 square feet of open teaching space, ideal for a dynamic educational environment. They are designed with safety and educational space in mind, featuring essential amenities such as heating and air conditioning systems, ensuring a comfortable learning space regardless of the weather. The interiors have either carpet or tile flooring, complemented by tile ceilings that enhance the acoustic quality of the room. Natural light is amply provided through slider windows, creating a bright and inviting space. Safety is paramount, evidenced by doors equipped with panic hardware and metal handicap ramps, ensuring accessibility for all.

* Remember that a used portable may look a bit shabby at first but with a fresh coat of paint and some cleaning it can be nicely converted into looking like new.

Refurbishing a Used Portable Classroom

A pre-owned portable classroom might initially appear worn, but it has the potential for transformation. With a fresh coat of paint and thorough cleaning, these classrooms can be revitalized, often resembling new structures. This makeover not only enhances their aesthetic appeal but also extends their functional lifespan, making them a wise investment for educational institutions. California Portables can also be repurposed into office and training spaces.

  • It really makes sense to search for a used modular building or classroom in order to save money if you are going to buy or rent space in California. For example I am aware of several used portable classroom trailers in Riverside, California. They are primarily 24' x 40' DSA models in good shape. With a good cleaning, fresh paint and changing the AC filters any one of these would be great for a school, church r daycare center program.

  • Hi Matt, I work for a realtor in Northern California (city of Livermore). Her listing on 5 acres just recently sold and the new buyer has requested that the modular building on this ranch property be removed. It's 24X60, axels, tires, wheels & hitch have been removed but are still at the property. I'm sure the owner would let it go for dirt cheap if it was removed at the buyer's expense (who knows, maybe he would be happy if it was just hauled away). I'm not sure if you deal in this area or know of anyone who could help us out. This needs to be removed as soon as possible. Can you give us any help or know of how we would go about offering these units to someone who could use them? I have pictures of the unit I would be happy to provide. Thanks, Vicki Ellis –
