A rule stated on these pages points to the document that makes it
A sentence on an answer page that states a Virginia rule, a deadline, a number or an office traces to a published source, and that source is listed at the foot of the page with a link to it.
Most of those sources are the documents themselves: a section of the Code of Virginia, a regulation in the Virginia Administrative Code, a Virginia Department of Health or VDOT page, a county or city office's own page. Where a page quotes a rule, the quotation is word for word, so you can find the same words at the source and read what surrounds them.
Where a question cannot be settled from a published record, the answer says so and names who settles it: the county building official, the local health department, the commissioner of the revenue, the settlement attorney. A name and an office are more useful than a rule that sounds right and cannot be traced. In a footprint where a town can carry ordinances its county does not, the office is often the most important fact on the page, and the six counties and Galax page sets out which office answers in each locality.
Rules, fees and office addresses change. Each answer shows the date it was last updated. Before acting on a deadline or a filing requirement, confirm it with the office that sets it.
