Converting Single Family Dwelling into a Business

Site Plan

The first step when changing the occupancy classification of an existing structure from Single-family dwelling to a business (B) use is to contact the Chesterfield County Planning Department to determine if the type of business is acceptable for the property according to the county zoning ordinances and to obtain an approved site plan, if necessary.

Building Permit

A building permit is required to convert a dwelling into a business office even if no alterations are proposed.
