Walls in Washington, D.C. homes: what to know before mounting a TV or building a media wall
Washington, D.C. has one of the oldest housing stocks in the country: about half of all units were built before 1960, and most residents live in apartments or attached rowhouses rather than detached homes. Brick rowhouses with plaster interiors and party walls dominate older neighborhoods like Capitol Hill, while larger apartment buildings use concrete, masonry and metal studs.

Common wall types
Brick rowhouses with plaster walls
Where: Capitol Hill, Georgetown, Mount Vernon Square, Shaw, Columbia Heights and other historic districts.
Mounting: Rowhouse side (party) walls carry the building load and are often masonry, while front and rear walls are generally not load-bearing. Interior surfaces are frequently plaster over lath or brick, so locate framing and use toggle or masonry anchors with slow pre-drilling.
Furred or exposed brick interior walls
Where: Renovated rowhouses and converted lofts, plus some pre-war apartment buildings.
Mounting: Anchor into the brick itself with masonry anchors, drilling into the brick face rather than the mortar joints where possible.
Poured concrete and masonry walls
Where: High-rise condos and apartment towers, and basements and foundations of older homes.
Mounting: Requires a hammer drill and concrete anchors. In-wall wiring is often impossible, so surface raceways are common.
Metal-stud drywall partitions
Where: Interior walls in mid-rise and high-rise apartments and condos, and in many renovated units.
Mounting: Use snap toggles or add blocking; flat mounts for modest TVs may be fine, but heavy TVs and arms need proper blocking or toggle anchors rated for the load.
Wood-frame stud walls
Where: Newer townhomes and infill construction, and partition walls in many older houses.
Mounting: Studs are typically 16 inches on center; lag the mount into at least two studs.
Tips before you mount
- Brick, block or concrete: anchor into solid material with 1/4" concrete screws or 3/8" sleeve or wedge anchors using a hammer drill and masonry bit. Drill into solid brick or the face shell of block rather than mortar joints where possible, and do not rely on plaster or furring alone.
- Plaster over lath (common in pre-war rowhouses): locate studs or joists first, pre-drill slowly, and use snap toggles where there is no framing. Plaster can crack, so expect some patching.
- Stud walls: studs are usually 16" on center. Lag the mount into at least two studs with 5/16" lag bolts, typically about 2.5" to 3" long; a full-motion arm puts much more leverage on the wall than a flat mount, so it should never hang on drywall anchors alone.
- Metal studs (common in apartments and condos): use snap toggles or similar toggle-style anchors rated for the TV and mount weight, or have the installer add wood blocking behind the drywall.
- Hiding wires: the National Electrical Code (NEC 400.12) does not allow a regular TV power cord to run inside the wall. Use an in-wall rated recessed power kit, and choose low-voltage cables rated CL2 or CL3 for in-wall HDMI and speaker runs. Brick and concrete walls usually rule out in-wall runs, so plan a paintable surface raceway, and note that exterior-facing brick walls in historic districts should not be drilled through for cables without checking the building rules.
- Over a fireplace: check the TV maker's heat limits and keep the screen out of rising heat; a mantel does not make the wall behind it cooler. Stone or brick surrounds need masonry anchors, not drywall anchors. Many rowhouse fireplaces are decorative or sealed; the installer should confirm the flue is not in use.
- Condos, co-ops and rentals: ask the association or landlord whether drilling into walls or concrete needs approval, and get the installer's certificate of insurance (COI) naming the association before work day. Many D.C. buildings are co-ops or condos that require COIs.
- Before work starts, tell the installer the wall type (studs, plaster, brick, block or concrete), the TV size and weight, and the mount type. These change the anchors, labor time and price.
