Planning an addition? Have one already? It all starts with good structural support, foundation and footings.
On this home’s addition, only 2”X6” material was used for the 1st floor joists. Then, where these floor joists extend and rest on the exterior foundation walls (left picture), they are notched-out making their support more like a 2”X5” or less. In the right picture, only one of three 2” boards used in the built-up wood beam supporting those 1st floor joists mentioned previously, extended the last 2’ of its length to rest on a single 2”X6” that was fastened with Tapcons® to the block foundation wall, crushing the wood in the process.
To say the least, the addition on the home is indeed curious. While this may have been all that we saw during the inspection that sent up red flags, it begs the question “What couldn’t we see?”. Unfortunately, a home inspection isn’t perfect…we don’t have x-ray vision and can’t see through walls. Besides, as a prospective home buyer you likely do not have the right as part of your home inspection condition in the “Offer to Purchase” to start tearing walls apart to see what’s going on. So, at this point, you would need to get further professional advice perhaps from a qualified building contractor and or structural engineer as well as the permission of the vendor / home owner to explore matters in greater detail.
Protect yourself…get it inspected!
