New Mexico is distinctive for adobe, rammed-earth and stucco-over-frame homes, particularly in Santa Fe, Taos and the Rio Grande valley. About 15% of units are mobile homes, one of the highest shares among U.S. states, and the climate is dry with strong sun and wide temperature swings.

Common wall types

Adobe and earthen walls

Where: Historic and revival homes in Santa Fe, Taos, Albuquerque's North Valley and Las Cruces; New Mexico has a dedicated earthen building materials code (14.7.4 NMAC) covering adobe, rammed earth and compressed earth block.

Mounting: Walls are thick and soft; there are no studs. Use mechanical expansion or sleeve anchors suited to earthen walls, and mount to a bond beam, wood nailer or blocking where possible. Do not use lightweight drywall anchors.

Stucco over wood frame

Where: Most newer Albuquerque, Rio Rancho and Las Cruces houses.

Mounting: Interior is drywall on studs, usually 16 inches on center. Lag mounts into studs.

Concrete block or masonry

Where: Some homes, especially in the south and for garden walls.

Mounting: Use concrete screws or sleeve anchors into solid block face shells.

Manufactured homes

Where: About 15% of all units, common in rural and metro-edge areas.

Mounting: Thin panels and wide stud spacing mean the mount must reach framing; heavy mounts may need added blocking.

Plaster and viga-and-latilla interiors

Where: Older Southwestern style homes, with exposed beams and plastered walls.

Mounting: Plaster over adobe or lath varies. Check what is behind the finish and use mounts with spacing for uneven, rounded wall surfaces.

Tips before you mount

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 far more leverage on the wall than a flat mount, so it needs studs or masonry and should never hang on drywall anchors alone.
Adobe walls: have the installer anchor into a wood nailer, bond beam or purpose-built blocking, or use appropriate sleeve or epoxy anchors in sound adobe. Soft adobe and old plaster can crumble, so heavy full-motion arms need a structural substitute.
Thick adobe and recessed niches (nichos) are often better places for a TV than a surface-mounted arm; ask for a built-in recess with framing.
Concrete block: use 1/4" concrete screws or 3/8" sleeve anchors with a hammer drill, placing anchors in solid face shells and avoiding mortar joints.
Hiding wires: the National Electrical Code (NEC 400.12) does not allow a regular TV power cord to be concealed inside a wall. Use an in-wall rated recessed power kit, and choose low-voltage cable rated CL2 or CL3 for in-wall HDMI and speaker runs. Thick adobe makes in-wall runs impractical, so a surface raceway or a pre-planned chase is typical.
Outdoor patios (portales): strong UV, summer heat and dust call for an outdoor-rated TV with a rated operating range, shade, and stainless or coated hardware.
Fireplaces: kiva-style corner fireplaces are common; keep TVs out of the heat path and do not hang heavy sets on old plastered fireplaces.
Before work starts, tell the installer the wall type (studs, plaster, masonry or concrete), the TV size and weight, and the mount type. These change the anchors, labor time and price.
