1.) Modular construction is a method of building, not a type of construction or a classification of occupancy.

• You won’t find “modular” as one of the five types of construction or as one of the ten major occupancy classifications in the building code because it is simply a method of construction where components or large sections of the building are built in a factory, then transported to the site where it is assembled.

2.) Modular construction is built to the same code as site-built / traditional construction.

• There is not a specific chapter or section of the base building codes dedicated to modular construction. However, it is generally included as industrialized buildings and is subject to the same related sections of the code.

3.) Modular construction is as strong, and often stronger, than traditional construction.

• In addition to the standard structural requirements set forth in the code, modular construction must also be engineered to withstand the added stress of being transported and then lifted into place.

4.) While there are cost saving opportunities with modular construction due to the method of construction, the major savings are often in the condensed construction timeline.

• When managed correctly, many of the construction phases can occur simultaneously. For example, the foundation and the main modular structure can be built in parallel. Additionally, the modular manufacturing process typically compacts much of the building process into a fraction of the time needed for traditional construction. A shorter construction timeline means faster occupancy and shorter loan cycles.

5.) Modular construction is built in a manner that protects it from the elements and helps to prevent damage due to adverse weather.

• State modular programs typically require materials to be protected from the elements and checked for quality prior to use. Additionally, building in a covered structure that is often climatically controlled not only makes for improved working conditions, but keeps the units protected from the environment that typically is an issue for site construction.

6.) Inspections requirements of modular products are often more stringent than traditional construction.

• Traditional site construction will at best get spot inspections by the Authority Having Jurisdiction, AHJ at 3 or 4 specified times during construction. State modular programs normally require the manufacturer to have a detailed quality program in place with regular daily inspections. This program is then audited by a third party to make sure the stringent inspection and documentation process is followed.

7.) Modular construction is not limited to simple small, box-like designs.

• Gone are the days of modular buildings being relegated to small rectangular structures with limited curb appeal and entry level markets. Modular and off-site construction is being used in everything from bath pods that are inserted into high rise structures to elaborate custom homes, from convent stores to elegant upscale boutiques, and from back yard mother-in-law suites to multi-story commercial structures. Like site construction, the only limit is physics and your imagination.

8.) State code modular products and HUD code products are built to different code standards.

• While both products are built in a factory and transported to the site for completion two different code types are in play. HUD code products are built to a national code standard known at the “National Manufactured Housing Construction and Safety Standard Act, CFR Part 3280 of the Code of Federal Regulations”. Modular products are built to the same State and Local codes governing a site-built structure for the specific location.

9.) You can use modular constructed products in State that do not have a modular program.

• State modular programs exist in 38 State currently and establish rules and regulations for their construction. For those State that do not have a formal State modular program you will need to work directly with your local AHJ to determine requirements and expectations for their use. This can vary from jurisdiction to jurisdiction, so it is important that you have this discussion each time, prior to construction of any type.

10.) Modular construction is not rocket science, but there is a learning curve.

• With the push to solve the housing needs of the country there is considerable interest in modular construction. It is true that the material, tools, workforce, and code are the same as site-built construction, but there are trade secrets and a number of hurdles to overcome. It is highly recommended that you work with and hire team members familiar with the process from design through set to increase your opportunity for success.
