“The most common room addition question I get: can we add a second story without a full foundation replacement? In most 1950s–1970s Valley homes, the answer is: it depends on the existing foundation's bearing capacity and soil type. Our first step is always a structural engineer's foundation assessment. If the existing slab can't handle the load, a foundation upgrade adds $40–80K.”
Specify the same flooring material in the addition as in the existing house before pulling the permit. Matching an existing floor after the addition is complete is expensive: matching vintage hardwood or discontinued tile is difficult and costly. Define the solution during design.
