Size Limits of Modular Home Construction
Modular homes are constructed off-site in climate controlled factories and then transported to your building site. Since they need to be transported they face certain size limitations. These limitations are based mostly on the state and federal highway regulations your home will travel on. Modular factories can produce much larger modules than most roadway overpass and turns can safely accommodate. Please keep in mind that we are talking only about size limitations of the individuals modules. Your modular home has no size limitation and can be 20 bedroom mansion if you so desire. It will just need more modules to be transported from the factory.
You may be wondering "If a finished modular home can be any size why should I care?" The reason why it is important is because every extra module adds time and cost to your modular home project. Each module will require another driver and flatbed truck to transport it. It will also increase the amount of work the crane will need to do. It also adds to the amount of connections and marriage walls that the local modular builder needs to deal with. You should try to keep the number of modules your home needs to a minimum.
The width of the modules will generally range between 10 and 15 feet wide It will depend on the variance allowed your local state transportation board and the condition of the local roadway to your building site. Modular home manufacturers have production jigs. These jigs are like molds that hold in place the wooden beams as they are being constructed into your home. By holding the wooden beams in place it allows the construction team to quickly layout your frame while making sure the spacing and alignment is perfect. If you require a special width that the modular home manufacturer does not have a production jig for you will face significant extra costs and a much slower building process. It is best to work within the width of the existing production jigs.
The length of your modules is limited by the turns on the route to your home. An experienced transporter can handle a 60 foot long module. It can be physically impossible to turn an 80 foot long module on some turns of the road. As mentioned above, the production jigs will influence the maximum length of the module.
The height of the modules is dictated mostly by the highway overpasses. The interstate highway overpasses in urban areas have a 14 foot clearance. Your modular home needs to travel under 14 feet while sitting on the flatbed trailer. To make your modular fit through this clearance it will have a maximum production height of about 11 feet. You can still have 10 foot ceilings if want. Don't worry about the roof. Modular home manufacturers build their roofs with hidden hinges to allow it to travel flat. Once your modules arrive at the building site, the local builder will erect the roof to your desired roof pitch (slope)
When it comes time to transport the modules of your dream home they will usually form a convoy with pilot trucks. These pilot trucks will help guide the wide loads through the streets and highways to get to your home safely. An experienced local builder will have scouted the route first and highlighted any possible issues (for example some low hanging telephone lines). This is one of the many moments it is important that you choose an experienced modular home builder.
If you are worried about the size limitations of the modular home you should talk with your local modular builder. Often it is possible to order the standard size modular home floor plan and have your local builder add on to it with on-site stick built construction . Combining the efficiency of systems built technology and custom on-site construction you can have the best of both worlds.
