Homeowner questions
Planning in City of Alexandria.
Where do I start with a home addition in City of Alexandria?
Confirm City jurisdiction and the proposed permit category before planning an addition, garage or whole-home renovation. Bring your property address, plat and room priorities to a design consultation.
Which local approvals should I check?
The City says most construction work, including new structures, additions, renovations and alterations, requires permits. APEX is its online permitting system.
What could limit the size or position of the project?
Alexandria is an independent city, not a county. A postal address using Alexandria can describe a property outside City boundaries; identify the actual reviewing authority first.
Can Mosaic handle design and construction?
Yes. Mosaic coordinates design, material selections, permits and construction. We also offer design and permitting services separately. Mosaic is a Virginia Class A licensed contractor, license no. 2705181959, with an office in Chantilly.
Can you give a guaranteed price or permit timeline online?
No. Existing conditions, site access, utilities, materials and reviewing authorities affect scope, pricing and timing. A consultation is a request to discuss your project, not a reserved appointment or an approval.
Local requirements can change. Guidance is general information, not an approval or a substitute for property-specific review.
