What has to happen to the old house before the new one starts?
A teardown on Pasadena's north side is the most common way our clients get a new house on a lot they could not buy today. The old house is not simply knocked down. Gas, water, and electrical are disconnected and capped with the utilities notified in advance, any septic tank or old fuel tank is located, and the City of Pasadena issues a demolition permit before a machine arrives. Mature trees worth keeping are fenced off at the drip line so the equipment does not compact the roots. Demolition itself takes a few days. The paperwork ahead of it takes longer.
Once the lot is clear, the old foundation comes out entirely rather than being built over, since a new slab on top of old concrete cannot be engineered honestly. The soil is then evaluated for the new foundation, and grading is set so the lot drains to the street or a swale rather than toward the neighbor. On the newer south-side lots toward Fairmont Parkway, site prep is simpler because the pad was graded by the developer, but the HOA's building envelope and the drainage plan the developer filed both have to be respected. Either way, a survey and a plat review come before the first drawing.
