Mobile office and storage container rental companies nationwide

Twelve mobile office and storage rental operators, plus JOLT, appear in this alphabetical directory dated October 22, 2026. The main commercial distinction is who prints rates: JOLT publishes rental pricing, Conexwest shows a starting storage rate, and the other operators use account access, rental-detail gates or quote requests on the products checked.

How should a buyer read the alphabetical entries?

Use product type first, coverage second and commercial terms third. An operator that offers storage is not automatically an office supplier for your project, and a nationwide statement is not a promise about the assigned unit. Alphabetical order gives every entry the same starting position; it does not imply a score for price, condition or service.

The date matters because pricing paths, operating names and coverage statements can change. Treat the entries as a shortlist for a specific procurement request, not as a substitute for an executed order. Take the same job ZIP, unit description, planned duration and delivery window to each candidate before comparing the returned numbers.

Who is listed, and why it is not a ranking.

• A company is listed when its own site rents mobile offices or jobsite storage and states nationwide or multi-region reach.
• Every cell is what that site said on the date shown. A term the site did not state reads "Confirm in the written quote" — it means ask, not that no term exists.
• The list is alphabetical. Reach claims are not comparable branch counts, so there is no score; the ranked list for the Rockies is the Mountain West directory.

"Storage only" means the pages we read offered no mobile office, not that the company could never supply one. JOLT's minimum depends on the unit and the state; its card above gives every case.

Which companies print a rate rather than asking for project details?

JOLT publishes office and storage rent through its current pricing schedule. The Base 20 ft office rents at $795/mo, and the 20 ft storage unit rents at $295/mo. Those are unit-rent lines, not a delivered project total, and the invoice also needs transport, recurring charges, selected additions and applicable tax.

Conexwest's 10 ft storage rental listing shows a starting monthly rate (conexwest.com, 10 ft storage rental, checked October 22, 2026). That is evidence of a printed starting rate for that product, not proof of a delivered price for every container or location. Keep the product length and quoted rental period beside the figure when you request the actual job proposal.

A public starting rate helps an estimator begin work without an account. It does not establish pickup cost, the minimum commitment or an office's included fittings. Compare a storage starting rate with another storage rate, then compare the rest of each proposal separately; a printed figure alone cannot tell you which complete project costs less.

Which operators put rates behind an account or rental-detail gate?

United Rentals' storage listing provides a sign-in option for account rates alongside a request for a quotation (unitedrentals.com, 20 ft storage product, checked October 22, 2026). Classify that as account access, not simply quote-only. Ask the account holder to preserve the chosen jobsite and dates with the rate so procurement can match the displayed price to the correct order.

Herc Rentals asks for a jobsite ZIP and rental duration to display accurate pricing on its storage listing (hercrentals.com, 40 ft storage rental, checked October 22, 2026). That gate is different from signing into an account. Record the duration entered, because a result based on one rental period should not be compared with a proposal based on another.

Sunbelt Rentals' 40 ft storage page asks for rental details to show local rates and availability (sunbeltrentals.com, 40 ft storage container, checked October 22, 2026). The checked US product establishes storage, not a mobile-office rental offering. For an office requirement, ask for the actual product proposal rather than assuming the general branch network supplies the space you need.

Which companies route the checked products to a quote?

Mobile Modular directs modular-office buyers to project pricing that includes delivery, installation and finishing (mobilemodular.com, modular office buildings, checked October 22, 2026). Mobile Modular Portable Storage's storage rental page also uses a quote request (mobilemodularcontainers.com, storage container rental, checked October 22, 2026). Keep those two businesses distinct in the bid list: one name should not stand in for the other's product or coverage statement.

Pacific Mobile Structures asks buyers to specify dimensions, layout and rental term through an online quote or regional contact (pacificmobile.com, mobile office trailers, checked October 22, 2026). Satellite Shelters directs mobile-office customers to a personalized quote (satelliteco.com, mobile offices, checked October 22, 2026). In either case, send the room requirement along with the duration so the returned proposal identifies usable space rather than only a product family.

PODS for Business uses a quote path for commercial storage (pods.com, commercial storage, checked October 22, 2026). Its checked business pages establish storage containers, not an office product. Wilmot Modular requests quotes for its mobile-office trailers (wilmotmodular.com, mobile offices, checked October 22, 2026), while Triumph Modular's storage product directs buyers to availability and pricing for the location (triumphmodular.com, 20 ft steel container, checked October 22, 2026).

WillScot's office-trailer page routes buyers to a quote (willscot.com, mobile offices, checked October 22, 2026). Its standard storage page also advertises online ordering, but that interactive pricing process was not tested in the October review. The supported distinction is therefore its checked office quote path, not an assertion that every WillScot product or transaction requires a sales quote.

For these entries, the product pages read on October 22, 2026 route pricing to the processes described above. That is a dated observation about selected products. It is neither a finding about every page an operator maintains nor a reason to label a resulting proposal expensive or inexpensive before reviewing it.

Which operators state a minimum rental commitment?

Pacific Mobile Structures answers the minimum-term question directly in its office-trailer FAQ: no minimum lease term. For the other eleven researched operators, the minimum is "Confirm in the written quote". That instruction means obtain the actual term; it does not mean the supplier has no minimum.

Do not convert billing language or scheduling advice into a minimum commitment. Satellite Shelters' building-planning FAQ prefers 30 days of advance planning, which addresses when to arrange a building, not how long the customer must rent it. Likewise, month-to-month language and a renewable billing period do not by themselves settle every product's minimum obligation.

JOLT's terms are a separate, stated case. Colorado offices and 40 ft storage require three months; Colorado storage in 10, 12 and 20 ft lengths requires one month. Every JOLT rental in another state has a 12-month minimum, including jobs in the other four fixed-fee Mountain West states.

Put minimum commitment next to expected occupancy in the comparison worksheet. A short field assignment and a longer minimum are different numbers, and the purchase order should reflect the contractual commitment rather than only the days staff expect to occupy the office. For each competitor's billing period, deposit and notice requirements, use "Confirm in the written quote".

How do nationwide and multi-region coverage claims differ?

Separate broad national statements from named regional coverage. Conexwest's home page states service in 48 states; Satellite's FAQ describes delivery to the lower 48; Pacific Mobile's locations page describes nationwide service through local representatives. PODS describes a nationwide transportation network on its business home page, while Mobile Modular's company history states nationwide modular-building service.

United Rentals' corporate overview identifies 49 states and every Canadian province, not a specialty-office branch count. WillScot's home page describes at least 275 North American locations, Herc's rental overview lists more than 600, and Sunbelt's about statement describes a North American network. None of those general network statements establishes a particular office or storage unit's availability at a particular branch.

Mobile Modular Portable Storage's location terms add a concrete boundary: service within a 150-mile radius of its locations, subject to availability. Wilmot's stated coverage is Mid-Atlantic, with service contacts in Maryland, Virginia and North Carolina. Triumph's company description identifies the Northeast, Mid-Atlantic and Great Lakes rather than claiming nationwide service.

For a multi-state program, separate the company-level shortlist from each site's order. Ask each candidate to confirm the job ZIP, product, delivery scope and receiving contact for every location. A supplier may fit one site and require a different arrangement for another, so one regional confirmation should not be copied across the entire program.

Why are several familiar brands not separate operator rows?

Mobile Mini and ModSpace belong under WillScot rather than creating additional independent entries. Mobile Mini's 2020 merger was followed by consolidation under the WillScot name in 2024; the ModSpace acquisition filing records its 2018 closing. The ownership evidence comes from WillScot's investor records (investors.willscot.com, brand consolidation and acquisition filing, checked October 22, 2026).

United Rentals' acquisition history places Pac-Van under General Finance Corporation, acquired on May 25, 2021. Mobile Modular identifies Design Space Modular Buildings and VESTA Modular as businesses that joined it. Count those names within their current operator families rather than treating an old sign, saved contact or prior invoice as evidence of a separate national bidder.

For procurement, the practical step is to identify the legal supplier and current product description on the new proposal. Keep the former name in your project records if it helps locate earlier orders, but compare the current agreement. A historical relationship does not establish today's minimum term, rate or transport scope.

The focused comparisons cover United Rentals, Pac-Van's current operator context and Sunbelt Rentals storage. Use those narrower questions after the directory has reduced your list to providers with an appropriate product and a confirmed delivery path.

Where does JOLT fit for a project anywhere in the country?

JOLT rents and sells container offices and storage from Gypsum, Colorado, and now accepts nationwide projects. The 20 ft office family includes Base, Grid-Free and Alpine; a separate 40 ft office includes an enclosed bathroom. Storage choices are 10, 12, 20 and 40 ft, with a welded lockbox on the one-trip containers.

For standard offices and storage, the state-by-state delivery rule separates two cases. Colorado, Wyoming, Utah, Idaho and Montana use published fixed transport fees for each unit in each direction, with equal delivery and pickup charges. For other states, including Alaska and Hawaii, JOLT quotes both moves for the individual project.

Send the unit selection and job ZIP using the national transport request. Allow one business day for the project desk's written delivered proposal; an inquiry received after the 5:00pm Mountain Time cutoff is counted from the following business day. The offer remains valid for 14 days, and the email's "Reserve this quote" link carries its delivery and pickup figures into checkout.

The standard delivery window is 2–4 weeks after reservation confirmation. JOLT Express is limited to Colorado and an eligible Base 20 ft office; equipment, fence and traffic-related rentals stay within Colorado, Wyoming, Utah, Idaho and Montana. For regional buying context, consult the Mountain West company comparison, but do not apply its geographic framing to every national order.

How should the written quotes be compared line by line?

Begin with the same physical assignment. Write the required length, office versus storage use, bathroom requirement, power arrangement and selected furnishings into every request. Then ask each bidder to identify the actual offered unit so a container office is not compared as though it were the same floorplan as a modular building or trailer.

Separate the unit rent from each recurring addition. JOLT invoices add a damage waiver, an environmental fee and applicable sales tax alongside rent and recurring upgrades. For competitor fees, protection arrangements and taxes, use "Confirm in the written quote" until the returned documents establish the charges and their calculation.

Make delivery and pickup separate lines even when their amounts match. Ask what placement or setup is included and whether additional requested accessories are priced independently. A quotation that combines those items may still be usable, but procurement needs enough detail to compare the same scope rather than assuming all transport proposals include identical work.

Give the field team a chance to review the equipment description before approval. The superintendent should be able to identify the required door arrangement, the intended office systems and the receiving location from the same request that procurement priced. If the office needs to operate before shore power is available, resolve that operating requirement as a product choice rather than leaving it as an unpriced assumption.

Keep each site's comparison independent when several projects are bidding together. One address may use JOLT's fixed transport schedule while another needs a project quote, and their minimum terms may also differ if one is in Colorado. A combined purchasing worksheet can summarize the orders, but retain the accepted unit, commitment and delivery scope for each individual job.

Compare exit conditions alongside the minimum financial commitment. Under Rental Agreement section 2, JOLT credits the deposit against invoice one; rent changes by the published escalator on each delivery anniversary. For pickup, section 16 of that agreement sets a written-notice requirement of at least 15 days. JOLT permits free cancellation when your written notice precedes the opening day of the delivery window by more than 14 days; for competitors' exit conditions, use "Confirm in the written quote".

Keep the dated proposal, the equipment description and the accepted changes together with the order. A buyer should be able to identify which delivery and retrieval scope was accepted without reconstructing a phone call. Choose after the product, project address, financial commitment and closeout requirements have all been put on the same footing.
