Modular jobsite buildings for rent or purchase
Compare modular jobsite buildings for offices, toilets, locker rooms and break rooms. Describe how the building will be used, then request rental or purchase quotes including the fitted equipment, delivery, connections and servicing.
What type of modular jobsite building do you need?
Describe the intended use and construction type: a wheeled office trailer, purpose-built modular building and converted shipping container are different products. Ask for the actual layout and equipment rather than relying on a shared size label.

Price the fitted building and the services
No verified US building price sample is published on this page. Ask for a quote for the intended use and actual fitted model; a bare container or empty building is not a complete jobsite facility installation.
Equipment
Specify the exact units, usable facilities, fittings and capacity for the proposed workforce and working hours.
Ready for use
Include delivery, unloading, supports, assembly, water and drainage arrangements, electricity and commissioning before work starts.
Throughout the project
Price cleaning, consumables, tank emptying and water replenishment, maintenance, emergency replacement and final collection.
Ask for the charge period, applicable sales taxes, minimum rental, extension and notice terms, and every delivery or collection charge. Commercial rental terms do not change the requirement to provide suitable employee facilities from the start and throughout the work.
Request an itemized quotationWhat dimensions should you consider for a modular jobsite building?
Ask for the dimensions of the model offered. A nominal length such as 20ft does not establish its external footprint, finished internal area or permitted occupancy.
External envelope
Request length, width, overall height and any roof, stair or equipment projection. These dimensions affect siting and transport.
Finished interior
Request clear dimensions after insulation, linings and services. Lay out furniture and required circulation before assigning an occupancy.
Installation details
Obtain equipped mass, approved lifting points, foundation and anchorage requirements, and the actual door clear opening.
There is no single US building size. The downloadable site-layout rectangle is an illustration, not a supplier model or an approved building design. Use the exact model drawing to assess local snow, wind, frost, fire, energy and access requirements.
A modular jobsite building must support the required facilities
Identify federal OSHA or the approved State Plan covering the employer and work. Construction sanitation and general-industry rules are different. Confirm facilities before work starts and maintain them throughout the project.
Confirm coverage for the employer and the work. Some State Plans cover only state and local government workers; private-sector work in those states generally remains under federal OSHA. Workplace sanitation and building or zoning approvals are separate checks.
Available, sanitary toilets
For construction under federal OSHA, 29 CFR 1926.51(c) sets toilet provision by workforce in Table D-1, with specific temporary-field and mobile-crew provisions. An approved State Plan can impose different or additional requirements. Establish the governing rule before choosing the number and type of fixtures.
Specify: Record peak workforce, shifts, fixture types, privacy, accessible use, travel time, safe access and servicing. Federal rules allow specified nonsewer facilities unless local codes prohibit them; portable toilets are not automatically acceptable for every site.
Handwashing and task-specific hygiene
Federal construction 1926.51(f)(3) requires lavatories at places of employment, with a specific exception for mobile crews and normally unattended locations having transportation readily available to compliant nearby washing facilities. Lavatories need hot and cold or tepid running water, cleansing products and hygienic drying. Employees handling harmful substances also need adequate washing near the work under 1926.51(f)(1). Hand sanitizer is not a general replacement for required soap-and-water washing.
Specify: Identify supply, drainage, freeze protection and cleaning. If a particular OSHA standard requires showers, 1926.51(f) specifies one shower per ten employees of each sex, or fraction, showering during the same shift. Assess hazardous-work decontamination separately.
Meals, breaks and shelter
Federal 1926.51(g) prohibits eating and drinking in toilet rooms and areas exposed to toxic materials. Provide clean, usable arrangements for breaks and meals, and identify state heat, sanitation and employment requirements. The federal sanitation rule does not establish a single national lunchroom floor-area allowance.
Specify: State simultaneous users, furniture, cooling or safe heating, ventilation and cleaning. Keep food and drinking supplies separate from contaminants. Include rest access, shade or cooling and emergency arrangements where required for the actual work and climate.
State examples apply only in their jurisdiction. US requirements, exceptions and official references.
Rental, new or used purchase: what to compare?
Start from the same intended use and equipment level. The period of use, moves and condition of the unit all affect the budget.
Rental for a period
Add up the rental charges, delivery and collection, and services. Ask about the minimum charge, extension rate and collection terms.
Get a quote for this optionBuying new
Ask for a detailed breakdown of equipment and options, lead times, warranty and installation costs. Allow for moves if the building will be relocated.
Get a quote for this optionBuy used
Ask for recent photos and check the roof, floor, insulation, doors and services. Add any necessary repairs and interior build-out to the purchase price.
Get a quote for this optionCompare the total cost over your expected period of use, including a possible extension. There is no universal number of months after which buying becomes cheaper than renting.
Preparing the site and delivery
Provide the delivery ZIP code and full project address so the supplier can quote installation and any necessary services. Establish permitting jurisdiction from the actual parcel and intended use; a ZIP code alone is not enough.
Truck access
Gate width, bends, slope, overhead obstructions and space to maneuver. Photos help the discussion.
Installation location
Distance from the truck to the position, ground conditions and any supports to be approved. State who will provide the unloading equipment.
Available utilities
Electricity, water and drainage depending on use. Give their distance from the building and ask for connection costs to be quoted.
Schedule and parties involved
Preferred date, acceptance of the unit, commissioning and maintenance. For rental, also plan access for collection.
Installation and regulations: key checksTemporary or permanent use, site occupancy and team needs.ExpandCollapse
Present the intended use, duration and parcel location to the responsible zoning and building authorities. Check building, fire, accessibility and utility approvals for the actual installation. A temporary jobsite use does not establish permission for a permanent office or housing. Public land and a public right-of-way may require separate permission.
Before fabrication or purchase, check the installation state's modular-building or commercial-coach program, including design review, inspections and labels. Texas's IHB program excludes a construction-site building defined as a commercial structure not open to the public, used at a commercial site by a person constructing a building, road, utility or other infrastructure or real-property improvement. This is a program-specific exclusion, not a general permit exemption. TDLR also says an otherwise exempt relocatable building bearing an IHB label must meet program requirements. See the Texas program FAQ, question 3.
Federal OSHA construction sanitation rules, general-industry rules and applicable State Plan standards have different scopes. Determine the employer and work activity before specifying employee facilities. Separately, the ADA Standards' construction exception concerns structures directly associated with actual construction processes; temporary use alone is not an accessibility exemption. Our jobsite facilities regulations guide explains the distinctions.

Your questions about modular jobsite buildings
What does a modular jobsite building cost?
Ask for a current quotation for the fitted model, condition, delivery, connections, servicing and any collection. This page does not publish a verified US site-building price sample.
How do modular buildings fit into the jobsite facilities plan?
A modular building can provide an office, locker room, restrooms or break area. A complete jobsite facilities plan coordinates the required uses across one or more buildings and any existing facilities. Describe the uses to cover, the workforce and what is already available.
What is the floor area of a modular jobsite building?
It depends on the actual model and interior build-out. Ask for external dimensions, finished internal dimensions and a furnished plan. A nominal 20ft label does not establish the usable area, occupancy capacity or US code compliance.
Can you buy a used modular jobsite building?
Yes. Check the condition of the unit and its equipment, then add transport, installation, connections and any repairs to the purchase price. Ask the seller to specify what is included and what guarantees are offered.
Do you need permission to install a modular jobsite building?
Requirements depend on the use, parcel location and duration under the rules of the relevant state or locality. Ask the responsible authorities about zoning, building and trade permits, fire and accessibility requirements, and any state modular-building program. A program exclusion does not establish a local permit exemption. Check separate permission for public land or a public right-of-way.
Mobile offices, office trailers and modular jobsite buildings
Specify whether you need a wheeled trailer, a building placed on supports or a converted shipping container. For sanitation, distinguish individual portable toilets from a restroom trailer or modular restroom building. Describe the use, dimensions, layout and equipment so quotes cover the same requirement.
