Home Additions · Alexandria
Why Alexandria homeowners hire us.
An Alexandria addition starts only after the parcel is confirmed, because an Alexandria street address can sit inside the independent city or in Fairfax County.
The City of Alexandria, in the American Community Survey 2024 five-year estimates, has 32,065 owner-occupied units and a median year built of 1974. Code Administration includes the Permit Center, property-maintenance inspections, new-construction inspections, plan review, and administrative services. City applications are filed in APEX. A county parcel uses Fairfax County Land Development Services.
The connection between the new room and the existing house is measured before drawings are finished. This Alexandria addition is priced with a free written estimate after a site walk once the parcel city or county is confirmed.
For this area, see Permits in City of Alexandria: what to expect.
Confirm the parcel
Do not choose the Alexandria Permit Center from the mailing address alone. Fairfax County Land Development Services is the building office when the parcel is in the county.

Questions about home additions in Alexandria
Who permits a home addition in Alexandria?+
Inside the City of Alexandria, the Department of Code Administration Permit Center takes the application in APEX. A Fairfax County parcel with an Alexandria postal address goes to Fairfax County Land Development Services instead. Confirm the parcel.
Which Alexandria ZIPs are entirely in the city?+
The city tax guide for new residents puts 22301, 22305, 22313, and 22314 entirely in the city. ZIPs 22302, 22304, 22311, and 22312 are shared with Fairfax County. The ZIP does not replace a parcel check. Electrical, plumbing, and mechanical work can need separate trade permits, which Real Elite coordinates and does not perform.
