I'm considering an addition to my 1400 sq ft ranch home. I actually need about 550 sq ft to add two bedrooms and a bathroom directly above the existing bathroom. I've heard mixed opinions from friends about whether this smaller addition would be significantly cheaper than adding a full second story (1400 sq ft), which would also include a second bathroom on that level. I'm trying to get a better understanding of the cost differences between these two options.

It really varies based on where you live and the specifics of your project, but if we assume around $250 per sq ft, then the smaller addition could run approximately $150k, whereas the bigger one would likely be double that cost or more. Keep in mind that you might save a bit with materials on the larger project, but the expenses can add up quickly with finishes. It's always best to get three bids to get a clearer picture.
Generally, a 550 sq ft addition will be quite a bit cheaper than a full 1,400 sq ft second level. The larger addition involves much more structural work, roofing, HVAC modifications, and finishes. While the cost per sq ft might be lower for the larger addition, the total price will still be significantly higher overall.
Just for general guidance, costs usually range from $250 to $350 per square foot for additions. The 1400 sq ft second level often comes out to 2x the price of adding a simple perimeter addition. And make sure your existing foundation can support another floor; this is crucial in estimation. If you haven't done so, talking to an architect can help you get accurate plans and quotes.
