“The hidden cost of room additions: temporary relocation or living in a construction zone for 4–8 months. In the Valley, clients who've tried to live in the home during a major addition usually report significant quality-of-life impact. Build temporary accommodation costs into your project budget if you have young children or work from home.”
Request that the contractor verify the existing foundation's condition at the new addition connection point before framing begins. The connection between the new addition foundation and the existing house foundation needs to be properly tied. Weak or misaligned connections create differential settlement that shows up as cracks and door alignment problems within 3–5 years.
