Why am I being asked to sign a lease or sale agreement?

Mobile Modular’s Lease Agreement or Sale Agreement document contains contractual language that pertains specifically to the leasing or selling of the equipment we offer. Our agreement outlines both our obligations to you as the Lessee or Buyer, as well as your obligations to us.

While we will consider using a customer’s purchase order or contract in lieu of our standard agreement if there are special circumstances, our preference is to use our standard agreement because the language is protective to both parties and is specific to the nature of the relationship between Lessee/Buyer and Lessor/Seller.

Please note that if you have concerns or questions or would like to negotiate changes to specific language in our agreement, our legal department will work with you to negotiate terms as needed.

What’s Personal Property Expense (PPE)? My company/organization is tax exempt. Shouldn’t we be exempt from paying PPE?

Personal Property Expense (PPE) refers to fees that may be imposed by local tax jurisdictions (usually counties) in most states or fees related to the titling and registration of rental equipment in the state of California, which are charged to the owner of the rental equipment.

It is a very common practice for the companies who rent equipment to pass this expense along to customers in the form of a fee charged on monthly rental invoices.

These fees are assessed against the equipment owner, regardless of whether the Lessee utilizing the equipment is tax exempt, therefore, your organization’s tax exemption status does not make your organization exempt from paying PPE.

Why does your contract say that it’s subject to credit approval? What does that entail?

Much in the same way that a credit evaluation would be conducted for leasing residential or commercial property, Mobile Modular needs to ensure that we’re entrusting our rental property to organizations who have the capability of meeting the financial obligations of leasing or purchasing our equipment and who will treat our property in an appropriate manner. Each order is reviewed by our Credit Department. Depending upon their review, your organization may be required to fill out a credit application, pay a security deposit and/or pay some charges in advance of delivery.

Why does your contract state that there will be a cleaning charge?

When equipment returns to us there are several things that need to be done to return it to our standard condition and get it ready to rent to the next customer. This charge is similar to what you would pay if you stayed in a vacation rental – our buildings are professionally cleaned before each shipment.

Your contract says that we’ll be charged for damages beyond normal wear and tear. What’s considered normal wear and tear?

What we consider to be normal wear and tear may vary depending on the length of time you keep the equipment. Generally speaking however, if you make any changes to the building that will need to be reversed and/or repaired before we can lease the building to another customer, there will be charges for the labor and materials involved in restoring the building to our standard specifications. Here are some specific things to be aware of:

  • Any objects, such as nails, screws, pipes, conduit, j-boxes or anything else larger than a thumb tack that penetrates either interior or exterior wall panels will require repairs or material replacement to return the equipment to our standard condition.
  • Use of chair mats to protect flooring from excessive wear patterns caused by rolling chairs is necessary.
  • Attaching items to walls with tape or other adhesives may cause damage which will require panel replacement. Use of thumb tacks is a good alternative.
  • Installation of phone and/or data wires, fire or other alarm systems may cause damage to wall surfaces requiring repairs or material replacement. If wires or conduits are left in place when the equipment is returned, there will be charges for the removal of those items.
  • Painting the exterior of the equipment any colors other than those the equipment arrived in may result in charges to repaint the equipment.
  • Painting interior wall panels will result in significant charges for replacement of materials
  • Making changes to finishes such as flooring, wall coverings, etc. will result in charges both to remove your materials and replace with our standard materials. While the finishes you select may be beautiful, we have standard finishes and need to maintain our fleet of equipment to those standards.
  • If locks have been rekeyed or if keys aren’t returned with the building, you may be charged to replace keys and/or locking mechanisms.
  • You will be responsible for any damage to the equipment resulting from graffiti, theft of components or other forms of vandalism.
  • Any alterations to the electrical panel will result in charges for returning the equipment to standard specifications.
  • Failure to remove personal property you’ve installed on or in the building, such as awnings, window coverings, posters or other décor, furniture, electronics or debris/trash, will result in charges for the removal and disposal of such items.
  • If any accessories or components such as window coverings, security screens/bars, marker boards, fire extinguishers, wall clocks, stairs, plumbing manifolds or fixtures were delivered with the equipment and are not returned with the equipment, there will be charges to replace such items.

Please familiarize yourself with our Service Guide ( to ensure you’re aware of your responsibilities for maintenance of the equipment while it’s in your care.

Why does your contract allow you to adjust prices?

We make every effort to provide a thorough and accurate quote for your project. There are times when it is not practical to conduct a thorough site visit prior to quoting or issuing a contract. Additionally, it is possible that we have conducted a site visit, however conditions on site may change between the site visit and time of delivery/set up. In those cases, we may pass along additional charges when appropriate, however we will make every reasonable effort to ensure you’re aware of the additional work needed and the resulting charges before proceeding.

  • Driver waiting time – this charge would be applicable if our driver arrives on site and is unable to proceed with delivering due to some unforeseen delay on your site.
  • Pilot car requirements – In some cases, cities or counties may require our hauling companies to have the building accompanied by a pilot car during transport for safety purposes. Our hauling companies will notify us prior to delivery if the county or city is requiring this service for your delivery. If pilot cars are required, we will inform you of the additional charges prior to your scheduled delivery, if we were unable to provide that information on the initial quote.
  • Special transport permits – These permit requirements are determined by individual counties or cities. Many times these items will be called out on the initial quote, however there are times when we are not informed that such permits are required until shortly before the scheduled delivery. If permits are required, we will inform you of the additional charges prior to your scheduled delivery.
  • Difficult site – There are times when site conditions require our vendors to maneuver the building into position because the designated placement of the building can’t be reached by the delivery truck, which requires additional labor. Similarly, there are times when the site is out of level which requires the vendor to do additional work to ensure the building is plumb. In some cases, it will be known and quoted in advance, however there are times when it is not possible to know about additional labor needs prior to delivery. If additional labor due to a difficult site is necessary upon delivery/set up, we will inform you of such charges when we become aware of them.
  • Increase in fuel price – generally speaking, we will not adjust our haul pricing due to fuel increases on deliveries. There may be unusual circumstances that would necessitate this, but they are rare. For example, if we issued a contract with one anticipated delivery date and you choose to delay the delivery for an extended period, we may find it necessary to adjust the hauling prices if fuel prices have increased dramatically since your contract was created.
  • Return related charges – The prices related to return of the equipment are quoted at the initiation of the lease and will be honored if the equipment is returned at or prior to the expiration of the initial lease term, barring unforeseen changes in site conditions which may necessitate additional work upon dismantle and removal. If the building is kept beyond the original lease term, the costs we pay our vendors for hauling and the preparation of the equipment for removal may have been adjusted between the time the lease initiated and when the return is taking place. In those cases, we must recuperate our costs and will provide you with a quotation detailing the current charges following your request to return the equipment.

Are there insurance requirements associated with renting a modular building?

Yes. Customers are required to provide the following insurance coverage:

  • General Liability insurance with a minimum limit of $1,000,000.00 per occurrence, naming Mobile Modular Management Corporation as an additional insured.

Why do you require Property Insurance? Can we obtain insurance through Mobile Modular? Do you offer a damage waiver?

Property insurance coverage is a policy created specifically for the rental of a specific piece of equipment. Your contract reflects the insurance value of the equipment you are leasing. When the equipment is in your possession, you are solely responsible for it. If anything happens to the equipment, such as vandalism, fire, theft, natural disasters, etc., you will be responsible for reimbursing Mobile Modular for the full insurance value of the equipment. It is in your best interest to obtain an insurance policy that will cover such a loss, were it to occur. Should you fail to obtain such insurance, you will still be held responsible for payment of the stated insurance value of the equipment, even if you don’t have the proper insurance coverage.

Can we obtain property insurance coverage through Mobile Modular or does Mobile Modular offer a damage waiver option?

At this time, Mobile Modular does not offer either insurance coverage or a damage waiver option.

read more read less

Why do you require General Liability Insurance?

We require this form of insurance to protect our company in the event of accidents, injuries or any other losses, lawsuits or other types of claims which may arise in connection with your possession or use of the equipment. While the equipment is in your care and/or possession, Mobile Modular cannot be held responsible for any activities occurring in, on or near the equipment.

read more read less

Why are we required to provide insurance when we are purchasing the equipment?

Until sale balance has been paid in full, Mobile Modular maintains title to and ownership of the equipment and therefore maintains an interest in the condition of the equipment. In the event that the equipment is damaged or destroyed between the time that the equipment is delivered/set up and prior to your payment for it in full, we must be certain that Mobile Modular will be paid for the remaining balance owed.

Why are we required to indemnify Mobile Modular?

A lot can happen in and around a modular building when it’s out of our care and control. As the Lessee, you are required to protect, indemnify and hold Mobile Modular harmless because we don’t have any control over what happens in, on or around our equipment when it isn’t in our possession. You as Lessee are solely responsible for anything that happens to any persons or property in, on or around the equipment. Our waiver and indemnification clause serves to enforces that responsibility should any legal proceedings be brought about in relation to your lease or use of the equipment.

Can the lease be extended beyond the original contracted term?

Yes. Following the completion of your initial lease term, your lease will continue automatically on a month-to month basis unless you schedule the equipment to be returned at the end of the lease term. You may also contact our office to request a formal extension of the lease for a specified period of time. In the event that you keep the equipment longer than the original lease term, the rental rate and dismantle/return delivery charges may be revised to reflect current market conditions. If you have questions regarding the extension of your rental term, contact us at 800-944-3442 or Email Us.

Will modular buildings meet all of the appropriate building codes?

Local building departments may require that foundation systems to be used in conjunction with the modular building installation meet either permanent or temporary standards. In addition, local building and planning departments have responsibility for determining the standards for handicapped access, site utilities and aesthetic elements (paint colors, roofline treatments, etc.). Mobile Modular is very experienced in working with local building authorities and can assist our customers in dealing with these agencies, as well as providing for any additional items that may be required.

  • California Buildings - All of Mobile Modular's buildings are approved by one of three different agencies: Department of Housing and Community Development (DOH), Division of the State Architect (DSA) or Department of Motor Vehicles (DMV). Each of these agencies has pre-emptive authority for the construction requirements for buildings falling under their respective jurisdiction.
  • Florida Buildings - All of Mobile Modular's buildings are approved by the Department of Community Affairs (DCA) and education buildings are also approved by Clemons, Rutherford and Associates (CRA). Each of these agencies ensures that such units, systems, or component parts are in full compliance with the Florida Building Code.
  • Mid-Atlantic Buildings - All of Mobile Modular's buildings in the Mid-Atlantic are approved for North Carolina Department of Insurance (NCDOI), Georgia Department of Community Affairs (DCA), Virginia Department of Housing and Community Development (DHCD), and Maryland/District of Columbia Department of Housing and Community Development (DHCD). Each of these agencies has pre-emptive authority for the construction requirements for buildings falling under their respective jurisdiction.
  • Texas Buildings - Although Mobile Modular has available both Texas Department of Licensing and Regulation (TDLR) decal and International Building Code Congress (IBCC) buildings, these agencies do not have preemptive authority for the construction of modular buildings. Prior to arranging for shipment of a building, it is important for customers to verify with their local building department what construction standards are required. Mobile Modular typically can comply with these requirements and will work with the local building department to meet their standards.

Custom Solutions FAQs

What is Permanent Modular Construction?

Permanent Modular Construction (PMC) is a construction PROCESS in which segments of a building (aka modules) are constructed offsite, transported to the project location, and assembled to provide a complete permanent building.

read more read less

Are the materials and finishes in Permanent Modular Construction different from those used in conventional construction?

It is best to think of PMC as a different process as opposed to a product. The exact same materials and finishes can be used in PMC.

Does Permanent Modular Construction meet the same building codes as conventional construction?

Yes, PMC must abide by the same building codes. This is typically the International Building Code (IBC).

read more read less

Is Permanent Modular Construction cheaper than conventional construction?

Yes, in many cases PMC is more economical. However, certain factors can impact this. Involving the PMC contractor early in the design process maximizes PMC efficiencies and cost savings.

read more read less

Is Permanent Modular Construction faster than conventional construction?

Yes, is PMC traditionally faster due construction process in which the building is being constructed offsite concurrently with onsite activities, such as foundations and site utilities.

read more read less

In addition to potential cost and time savings, what are the other benefits of Permanent Modular Construction?

SAFETY: PMC building modules are constructed in a manufacturing environment and benefit from the use of controlled processes, a broad range of material handling equipment, and environmental conditions not afforded to conventional site built construction.

QUALITY: PMC manufacturers employee Quality Control Departments and utilize Quality Checklists to inspect the buildings throughout every stage of the manufacturing process. These QC Departments are in addition to the independent third party inspection agencies, mandated by various code-governing bodies, who perform regular inspections of the buildings while on the manufacturing assembly line. Additionally, PMC manufacturers have a lower employee turnover rate when compared to conventional contractors. A stable workforce performing similar tasks on a daily basis provides for inherently higher quality.

SCHEDULE CERTAINTY: PMC is not subjected to as many potential weather delays as conventional construction due to the indoor manufacturing environment in which the modules are constructed.

LESS SITE DISTURBANCE: A typical PMC project sees between 60%-95% of the building completed offsite at the manufacturing facility. This has a direct impact on the reduction in onsite construction activity, equipment, workforce, material deliveries, and noise levels.

Air Care FAQs

Is there a minimum time frame required when enrolling in the for the filter replacement program?

Ideally, signing up for our AirCare program at lease inception is the best time as it allows us to ship your building with a new HVAC filter already installed along with 2 replacement filters shipped inside the building. However, you can sign up at any time during the course of your lease for enrollment in our AirCare program. Please allow a few weeks for us to enroll you in the program and coordinate delivery of your filters to the jobsite.

Is there a penalty if filters are not changed monthly?

Our contract requires the regular, routine maintenance of our buildings, including the mechanical systems. Regular air filter changes on the HVAC are a critical component of maintaining the HVAC and allowing it to operate within its normal operating parameters. Dirty air filters can degrade the performance of the HVAC or cause critical components to fail. If the HVAC fails and it’s determined that the failure is due to not changing the filters, the service call and repairs may be charged back to you.

Can a Mobile Modular service tech change the filters for me monthly?

We don’t currently have a program where we perform EVERY Filter change, but changing the air filter is a quick and simple process. For a video to guide you through the process, just click HVAC Filter Change Video or follow this guide HVAC Filter Change PDF.

If you are still looking for a bit more, enroll in AirCare Plus and receive regularly scheduled deliveries of premium air filters for your heating and cooling system. Shipping is automatic and absolutely free. A MMMC technician will inspect your unit quarterly to ensure all components are functioning properly and clean unit coils (and our tech will change the filter while he’s there for you, too).

With the “Plus” filter replacement service, how often will an HVAC service technician inspect the system?

The technician will check to make sure the unit is functioning properly and will clean the coils 4x a year.

If our business uses MERV-13 or HEPA filters, will Mobile Modular check that our HVAC system can handle these types of filters? (i.e. pressure drop issues for HVAC fan can result from use of higher-grade filters—air flow through filter must be checked more carefully.)

Our HVAC’s are designed for MERV-13 filters. The MERV-13 filter excels at capturing smaller particulates in the air than lower MERV rated filters, but you may have to change the filters more frequently. Our HVAC systems are not designed to accept HEPA filters and they should not be used on any HVAC system not specifically designed around them.

Is there a difference between air filtration and air cleaning?

Yes. Air filters catch and eliminate a lot of contaminants, including dust, dirt, and even some viruses, assuming you use a high-efficiency air filter (MERV 13 or higher, and even better, a HEPA filter). But for any contaminants that an air filter doesn’t catch (i.e., normal air exchange in a room, particulates too small to be captured by the air filter, or contaminants introduced into the room by people during normal respiration), an air cleaner helps eliminate contaminants not captured by the air filter.

How do I determine if fence panels or chain link fence is better for my site?

Fence panels are the most versatile and easy to use for general temporary fencing. Chain link is used for sites with steep or inconsistent grades.

What is “barricade” fencing and when can it be used?

Barricade fencing is lighter-weight and shorter than other fencing options. It is sometimes called “bike fencing” because it can be used as a temporary bike rack. Barricade fencing is easily hooked together to create a boundary at events like races, fairs, concerts, or any other event where spectators want to see the action while staying safely at a distance.

In what conditions should I lease a wind screen with the fence?

A wind screen will protect your site from dust and dirt. Consider the intensity of the prevailing winds at the site—if it’s common to see dust blowing, wind screen might be a good idea. An added benefit of wind screen is privacy--it hides the site from the public. People are less likely to break in to a site if they cannot see what’s inside.

Is the customer responsible for clearing trees, bushes, or other obstructions where fencing is to be installed, or is this “prep work” done by Mobile Modular?

YES, in the unlikely event that this is required. We require a clear path to install the fencing, BUT we have multiple fencing options that should be flexible to meet any of your site requirements.

What if the site where I need fencing is rocky, uneven grade, hilly, and/or has lots of obstacles. Can a fence still be installed?

Absolutely. Chain link fences with ground installed posts are ideal for this scenario.

What if there is damage to the fence while it is installed temporarily at my site? Is the customer liable for repair/replacement costs?


What are some examples of “custom signage” I can order to be placed on the fence? Does Mobile Modular install the signs?

Custom signage is available to be printed on the wind screens. All we need is camera ready art to produce YOUR signage. Logos, company mottos and phone numbers, project advertising, the possibilities are literally limitless.
