Used California Portable Classrooms can solve space needs for private schools, churches and businesses. Here’s how to find and buy one.

California’s educational landscape has long embraced portable, modular classrooms as a practical solution to space challenges. These structures have become a mainstay in schools across the Golden State, offering flexibility and functionality. Today, many of these classrooms, steeped in practicality and versatility, are available for purchase or rental. This comprehensive guide delves into the nuances of acquiring a used portable classroom in California, mainly focusing on the state’s largest counties, such as Los Angeles, San Diego, Orange, Riverside, and San Bernardino.

Understanding California DSA Portable Classrooms

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. While 24 feet by 60 feet and 32 feet by 30 feet are other standard sizes, the 24 by 40 is the most common. 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 room’s acoustic quality. Natural light is amply provided through slider windows, creating a bright and inviting space. Safety is paramount, as evidenced by doors equipped with panic hardware and metal handicap ramps, which ensure accessibility for all.

Finding the Perfect Used Portable Classroom in California – For an Affordable Price

Here, we offer detailed guidance for those in the market for a cost-effective classroom solution:

  1. Space Assessment: Before proceeding, assess the space requirements for your school, church, or daycare program. Calculate the necessary area by considering the number of students and teachers and factor in additional space for furnishings. This step is crucial in ensuring that the chosen classroom meets your needs.
  2. Location and Duration Planning: Identify the location where the portable will be placed. Additionally, ascertain the duration for which the space will be required. This foresight aids in selecting a classroom that aligns with spatial and temporal needs.
  3. Permits and Zoning: Contact your local building and safety department to understand the permit requirements for installing a portable classroom. In most instances, securing a permit is a necessary step to ensure compliance with local regulations and safety standards.
  4. Once steps 1-4 are ready, try calling your local school districts, private schools, and churches. Start with the facility manager or facilities department and inquire about the availability of any used Portables. Or, contact iModular! Our online form simplifies locating the best deal on a used portable classroom in California.

* Remember that a used portable may look shabby at first, but with a fresh coat of paint and some cleaning, it can be nicely transformed 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 enhances their aesthetic appeal and extends their functional lifespan, making them a wise investment for educational institutions. California Portables can also be repurposed into office and training spaces.

Converting a DSA Classroom to an HCD Classroom in California

If you’re purchasing a used DSA-approved portable classroom and planning to use it in a private school, daycare, or commercial setting, you may need to convert it to an HCD (California Department of Housing and Community Development) building. This is because DSA approval applies to public school facilities, while HCD governs factory-built housing (FBH) and commercial modular buildings.

Why Convert from DSA to HCD?

  • DSA approvals are specific to public K-12 schools and do not apply to buildings placed on private property.
  • HCD certification ensures compliance with California Code of Regulations (CCR) Title 25, which applies to private schools, businesses, and other non-public entities.
  • Converting allows the building to be legally installed and permitted in locations outside of public school districts.

Steps to Convert a DSA Portable Classroom to an HCD Classroom or Office

1. Verify the Existing Approvals & Documentation

  • Locate the DSA approval number and construction drawings from the original manufacturer.
  • Check if the unit has an existing HCD Factory-Built Housing (FBH) or Commercial Modular label (some buildings were dual-certified at the time of manufacture).
  • Contact the local building department where the unit will be installed to confirm permitting requirements.

2. Hire a Licensed HCD Modular Building Manufacturer or Engineer

  • Work with a licensed HCD manufacturer or structural engineer familiar with modular conversions.
  • The building must be inspected for compliance with HCD Title 25 regulations.
  • Potential modifications may include:
    • Structural reinforcements to meet wind, seismic, or snow load requirements.
    • Energy code updates (Title 24 compliance for private structures).
    • Electrical and plumbing modifications to meet local codes.

3. Submit Plans for HCD Approval

  • If modifications are required, a set of stamped drawings and an HCD permit application must be submitted.
  • HCD will review and issue an FBH certification number or require on-site inspections.

4. Obtain Local Permits

  • Once HCD approval is secured, the next step is obtaining local building permits for installation. This includes:
    • Foundation design approval (if required).
    • Utility connections (electric, water, sewer).
    • ADA compliance, fire alarms, and egress requirements.

5. Installation & Final Inspection

  • A licensed modular building contractor will install the classroom per HCD and local codes.
  • Local inspectors will conduct final approvals before occupancy is granted.

Cost Considerations

  • Engineering & HCD Permit Fees: $3,000 – $8,000 (depending on modifications).
  • Structural & Code Compliance Upgrades: $5,000 – $15,000+ (depending on the building’s condition).
  • Installation Costs: $10,000 – $25,000+ (varies based on foundation type and location).

  • 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.
