Colorado has some of the highest indoor radon levels in the country, and mitigation is a routine inspection objection rather than an unusual one. In Denver specifically, a large share of the housing stock predates 1950, so plaster walls, cast-iron and clay sewer lines, knob-and-tube remnants and original single-pane windows all turn up regularly.

Permits: Denver issues its own building permits through Community Planning and Development; the city and county are the same jurisdiction here.
