Rent Modular Buildings in Dallas, TX for Offices and Classrooms
Need more space fast? Texas State Modular rents and sells modular buildings across Dallas-Fort Worth. We supply job site offices, portable classrooms, and temporary commercial space. Units ship from our own in-stock fleet, so you skip the long build times of site construction.
We work as a full-service general contractor. One point of contact handles design, permits, delivery, and setup.
Temporary and Permanent Modular Buildings
Temporary Modular Buildings
These relocatable structures suit short-term space needs. Common uses include:
- Job site trailers and construction offices
- Temporary classrooms and swing space
- Sales offices and project trailers
- Break rooms and crew space
You can move them, reconfigure them, and return them when the project ends. That flexibility is why contractors and school districts rent instead of build.
Permanent Modular Construction
Permanent modular construction, or PMC, is a building method rather than a building type. Manufacturers build the modules in a factory. Crews prep the site and foundation at the same time. The two tracks run in parallel.
The result meets the same building codes as site-built construction. Permanent modular buildings offer:
- Factory quality control and inspection at every stage
- Shorter project timelines
- Architect-specified materials including wood, steel, and concrete
- Full customization to your floor plan
Temporary Buildings for Rent Across Dallas-Fort Worth
Temporary buildings solve a specific problem. You need working space now, and you need it gone later.
We rent temporary buildings for construction sites, school campuses, retail pop-ups, and emergency response. Ask about these when you call:
- Delivery timing. In-stock units with no changes move fastest. Custom work adds time.
- Site prep. We handle site preparation, foundations, and utility connections.
- Access. Every unit can be fitted with ADA-compliant decks and ramps.
- Separate line items. Budget for delivery and pickup, blocking and leveling, steps and ramps, and utility connections on top of the monthly rate.
Need a workspace on wheels instead? Our mobile office trailers and Conex container offices cover smaller footprints and tighter sites.
Modular Classrooms and Portable Classrooms for Texas Schools
Enrollment grows faster than campuses do. A portable classroom adds seats in weeks instead of years.
Dallas ISD makes the point better than we can. In its Bond 2026 FAQ, the district reports about 700 portable classrooms still in use, serving nearly 10,000 students. Voters approved the $6.2 billion bond on May 2, 2026. It funds 26 replacement schools over the next five to ten years. Districts running that kind of construction need swing space while the permanent buildings go up.
We supply modular classrooms for rent and sale across North Texas. Districts use them as:
- Standard instructional classrooms
- Science and computer labs
- Libraries and media centers
- Administrative offices and counseling space
- Swing space during a bond construction project

Should Your District Rent or Buy?
Rent when the need is temporary. Bond construction, storm damage, and enrollment spikes all pass. A lease keeps the asset off your books.
Buy when the need is structural. If your campus will be short on space for five years or more, purchase math usually wins. Used units cut the cost further, and we cover the tradeoffs in our guide to buying a used modular building.

Texas Modular Building Codes and TDLR Rules
Buyers ask whether modular buildings meet Texas code. They do, and the rules are specific.
The state agency in charge is the Texas Department of Licensing and Regulation, or TDLR. It runs the Industrialized Housing and Buildings program. The law behind it is Chapter 1202 of the Texas Occupations Code. That statute took effect on January 1, 1986. TDLR calls these units industrialized buildings.
Effective July 1, 2024, industrialized buildings in Texas must meet these code editions:
- International Building Code, 2021
- International Mechanical Code, 2021
- International Plumbing Code, 2021
- International Fuel Gas Code, 2021
- International Existing Building Code, 2021
- International Energy Conservation Code, 2015
- National Electrical Code, 2020
Approved units carry a TDLR decal or insignia. Ask any supplier to show you theirs.
When TDLR Approval Does Not Apply
Not every unit falls under the program. Section 1202.003 leaves out construction site buildings. It also leaves out units on temporary foundations that are closed to the public or under 1,500 square feet.
School buildings are the exception. That size carve-out specifically excludes structures used as a school or place of religious worship. In plain terms, a job trailer and a portable classroom follow different rules.
We handle permit acquisition as part of our turnkey service, so we sort out which path your unit takes.
Delivery Across Dallas-Fort Worth and Beyond
Our yard sits at 9120 Sally’s Way in Alvarado, TX, just south of the Metroplex. We cover all of Dallas-Fort Worth from there. A shorter haul means lower freight and a faster set date.
We started in Texas and grew from there. Project managers now cover Oklahoma, Arkansas, and Louisiana. When you call, you reach someone local instead of a national call center.

Why Choose Modular Construction?
Modular construction wins on speed and cost control. Here is what the trade body reports.
- Speed. The Modular Building Institute reports that running factory production and site prep at the same time can cut construction schedules by 30 to 50 percent.
- Minimal disruption. MBI puts the share of work completed offsite at 60 to 90 percent. Your campus or business keeps running while the modules get built.
- No weather delays. Factory production does not stop for North Texas rain, heat, or hail.
- Cost control. Shorter schedules cut general conditions and jobsite overhead.
- Flexibility. One method covers offices, classrooms, clinics, locker rooms, and specialty structures.
The method is not fringe. MBI’s 2026 industry report valued the North American permanent modular market at $24.5 billion for 2025.
Buildings can also be specified with recyclable materials, solar panel options, LED lighting, and upgraded insulation.

FAQs About Modular Buildings in Dallas
What is the difference between temporary and permanent modular buildings?
Temporary units move. You rent them for job site trailers, swing space, and portable classrooms. Permanent units stay. They are built offsite to full code, then set on a permanent foundation for the long haul.
How much faster is modular construction than traditional building?
The Modular Building Institute reports schedule cuts of 30 to 50 percent. Factory work runs at the same time as site prep. Indoor builds also dodge weather delays.
How much does it cost to rent a modular classroom in Texas?
Other suppliers publish lease rates near $1.00 to $1.50 per square foot per month for a standard temporary classroom building. Your quote depends on size, restroom setup, term length, delivery distance, and site work. Call us with your square footage and term.
How long does delivery take?
In-stock units with no changes move fastest. Custom builds run longer because they go through factory production and design review. Call us with your site details and we will tell you where you stand.
Do modular buildings meet Texas building codes?
Yes. TDLR reviews them under Chapter 1202 of the Occupations Code. Since July 1, 2024, they must meet the 2021 International Building Code. Related 2021 codes apply too, plus the 2020 National Electrical Code. Approved units carry a TDLR decal.
Do I need a permit for a modular building in Dallas?
Usually yes. Local permitting still applies even when TDLR has approved the building design. Permit acquisition is part of our turnkey service.
Can I buy a used modular classroom or office?
Yes. Used units cost less and often deliver faster. Condition, remaining service life, and code status vary by unit, so inspect before you buy.
Can a modular building be customized for my industry?
Yes. We build for schools, clinics, job sites, retail, and government. Custom work covers finishes, flooring, lighting, ADA decks and ramps, electrical, plumbing, HVAC, foundations, and utility hookups.
Do you buy or consign used modular equipment?
Yes. We handle sales and consignment of modular equipment. Call us if you have a unit to move.
