If your home no longer fits your growing family but you aren’t yet ready to move, it may be time to consider adding on to your property. Many homeowners opt for a second-story addition because of the remarkable amount of space it adds. Here’s some more information about how much second-story additions typically cost.
It’s important to note that a second-story addition does cost, on average, about 20% more than adding that same square footage to the first floor. This usually translates to about $100-$300 per square foot (professionally-built) for an addition that includes 2-3 bedrooms, a bathroom and stairs.
However, if the floor plan is more complex in nature or uses high-end materials, your second-story addition could cost as much as $400-$500 per square foot.
Additional costs usually include the cost of hiring a structural engineer to check out your home’s foundation beforehand ($200-$700), and hiring an architect to draw up precise plans of the addition ($700-$10,000).
Then, you should also factor in building permits that must be obtained, as well as a inspection by the local city officials. The best way to figure an exact cost for your project is to get a price quote from a licensed contractor. Only then will you be able to budget and plan accordingly.
