If you are trying to tell if your home is a modular home, but are unable to locate a UBC sticker, you simply need to do more research. The UBC sticker found in the majority of modular homes is just one of the easiest ways to know for sure that the home is a modular home. If you cannot find the sticker, but your home is supported by the perimeter of the house and you have blueprints that help show that your home was likely made off-site, you can predict that it is a modular home.
