Summary

Enclosing a carport or converting a garage into living space requires building permits and must meet the Virginia building code and zoning. A structure open on fewer than two sides is treated as a garage. Creating a separate dwelling needs a Conditional Use Permit.

These county ordinances apply to unincorporated areas of Chesterfield County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

A carport is a structure open on at least two sides used generally for covering vehicles ... If the structure does not open on at least two sides, it shall be considered a garage and will have to comply with all code requirements for garages.

Full Breakdown

Chesterfield distinguishes carports from garages: a carport open on at least two sides is a carport, but if it is not open on at least two sides it is a garage and must meet all garage code requirements. Enclosing a carport, or converting garage space into habitable rooms, is a building-code alteration requiring permits and inspections under the Virginia Uniform Statewide Building Code. Converting a garage into a separate rental or in-law unit creates a second dwelling, which is not allowed by right and requires a Conditional Use Permit plus zoning approval.

Violations & Fines

Converting or enclosing garage space without permits, or creating an unapproved dwelling, is a code and zoning violation subject to correction orders, fines and possible removal of the work.

Frequently Asked Questions

Can I turn my garage into a bedroom?
Yes, with building permits meeting the Virginia building code. If it becomes a separate living unit with its own kitchen, you also need a Conditional Use Permit.
Is enclosing my carport allowed?
Yes, but once it is closed on more than two sides it becomes a garage and must meet all garage building-code requirements, so permits and inspections are required.
