The person (or company) that built your house can clue you in on the exact structure of the house. If construction was recent, they may not even charge you for a quick call or consultation. Even if they do, keep in mind that a relatively small fee is nothing compared to the disastrous structural damage that can result from tearing down a load bearing wall. If you can't figure out which walls are load bearing and no one you call seems to know, you may want to hire a professional building inspector. Paying for an hour of a building inspector's time is definitely worth it if you want to remodel safely. Home inspections typically cost several hundred dollars. This rate can vary depending on the market and the size of the house - some high-end estimates can be as high as $1,000. Some independent companies offer their services to help would-be home improvers decide how to proceed with their project. These companies may employee construction managers, interior decorators, and other experienced home improvement experts. When it comes to modifying a wall that you're not sure is load bearing, these companies may be able to tell you what changes are possible, what changes are unsafe, or even answer the question of whether the wall is load bearing or not outright. If you're interested in this route, research companies in your area online to ensure you pick a credible, reliable company. Avoid removing a wall yourself unless you are extremely confident it is not bearing a load. As stated before, removing a load bearing wall can cause structural weakening and even potentially life-threatening structural collapse. Keep in mind that renovations are semi-permanent, so removing non-load bearing walls may change what additions you can make to your home in the future.
