What Kings County's reading doesn't cover

Two lots a mile apart in Kings County can carry different soil, even though they share one countywide reading. A local geotechnical report, typically $1,000-$5,000 (around $2,700 typical), is the only way to know what one lot in Kings County will actually do.

What it costs to find out, versus to ignore it

A geotechnical report runs $1,000-$5,000, typically around $2,700. Foundation repair, if a specific lot turns out to differ from the county average, runs $5,000-$15,000.
