Demolition Contractors in Altadena, CA

Most calls we get for demolition contractors in Altadena now come from families rebuilding after the Eaton Fire. The fire started on the evening of January 7, 2025, during strong Santa Ana winds, burned about 14,000 acres by January 10, killed 19 people, and damaged or destroyed more than 9,000 structures. The U.S. Army Corps of Engineers finished clearing ash and debris from more than 5,600 private properties in the Eaton Fire footprint in August 2025. That work cleared the burned debris, but many lots still have slabs, footings, chimneys, retaining walls, pools and driveways that have to come out before a new foundation can go in.

What is usually left on a cleared lot

• Slabs and footings that heat cracked or that do not suit the new house plans
• Chimneys and masonry walls still standing but no longer safe
• Pools and decks, often damaged and full of debris
• Driveways, walks and retaining walls that need to be removed or rebuilt
• Detached garages and outbuildings that were damaged but not destroyed

We look at each piece with your builder or engineer and remove what has to go, leaving what can be reused.

County rules, not city rules

Altadena is unincorporated, governed by the Los Angeles County Board of Supervisors, so permits go through Los Angeles County Public Works Building and Safety. The county's demolition guidance requires asbestos information with the application and an AQMD notification before the permit is issued, an existing sewer line capped and inspected, and pool demolition done to the code's pool appendix. Its construction and demolition debris ordinance calls for a Recycling and Reuse Plan, with at least 70 percent of mixed C&D debris recycled or reused. We prepare those documents and keep the weight tickets.

A historic foothill community

Altadena sits at about 1,358 feet at the foot of the San Gabriel Mountains and averages about 21 inches of rain a year, more than 6 inches above Los Angeles. Its older homes include 160 steep-roofed houses built from 1924 to 1926 in what is now a heritage area, and mansions on Millionaire's Row along Mariposa Street dating to the late 1880s. The county's guidance notes that a listed historic structure damaged by a natural disaster may not be demolished without approval from the State Office of Historic Preservation, unless it poses an imminent threat. If your home had historic status, we check that before anything comes down.

Slope and storms

Burned hillsides shed water and sediment fast. On sloped Altadena lots we install fiber rolls and keep a stabilized exit before winter, and we avoid leaving open excavations during storms. Call (213) 377-6198 to walk your lot with us.
