CommentsOnly on on-site inspection of the house will reveal for certain what the structural condition is of your home. However, sagging floors are not uncommon in older homes. In particular, you have a 15' x 23' floor with no interim supports. Depending on how it's built, it's possible that the lumber has deformed over time or was undersized compared to today's building codes.
As a data point, our living room is nearly exactly the same size: 15' x 22'. We built it with 3x12 joists (yes, 3x12) on 16" centers going the short span (15'). On top of this, we glued and screwed 1-1/8" plywood subflooring. The result? A very stiff floor. You jump on it and the bounce is virtually nil -- just the way I like my floors.
Bottom line is, thre is probably insufficient support. And while it may not be a structural hazard, the sag may be unappealing. On the other hand, it adds character and is what makes older homes unique.
If you're concerned about structural safety, we do recommend that you consult with licensed structural engineer in your area who can evaluate the foundation as well as framing members. Anything is possible to fix....all you need is time, money and knowhow!
