Permits & Planning for Additions in Washington DC

Home additions in DC require building permits through DCRA and must comply with zoning regulations governing lot coverage, rear yard setback, and building height. Many DC rowhouse lots have limited rear yard depth, making setback calculations a critical first step — TAV Remodeling reviews zoning compliance before scoping any addition. In historic districts such as Georgetown, Capitol Hill, and Dupont Circle, exterior additions are subject to design review by the Historic Preservation Office (HPO). We prepare HPO submissions and manage that review process alongside DCRA permitting.

Second-story additions require structural engineering for load transfer, foundation assessment, and coordination of electrical and HVAC systems across levels. All of this is managed by TAV Remodeling under a single fixed-price contract, with a written project timeline before construction begins and no changes to scope or cost without your written approval.

Home Additions Across Washington DC

We serve homeowners throughout Washington DC — Georgetown, Capitol Hill, Dupont Circle, Cleveland Park, Petworth, Brookland, Tenleytown, and Northwest DC neighborhoods. Rear additions are the most common type in DC, typically extending the kitchen or main living area 10–20 feet into the rear yard. Second-story additions are common on one-story rowhouses and detached homes where zoning height limits allow, and primary suite additions frequently occupy the full footprint of a new upper level.

TAV Remodeling evaluates your lot, zoning classification, and existing structure during the initial consultation to identify the most feasible addition approach for your goals and budget. We provide free 3D design before any contract is signed — so you can see the proposed addition in context with your existing home before committing to construction.
