Since 1882 Larsen Lumber has been providing quality lumber and building materials to homeowners and professional contractors. Our basic philosophy is to buy from top grade lumber mills with the purpose to exceed our customer's expectations. Our sales staff has a minimum of 20 years and is knowledgeable about the latest technology in the building industry. Having our own milling department, we can cut any lumber or plywood to size and surface wood to different thickness and widths. Larsen Lumber has recently been acclaimed as the 5th oldest family owned lumberyard in the USA.

Over 130 Years in Business

Larsen Lumber has been owned and operated by the Larsen family of San Leandro since 1882 when Jens Larsen, a Danish immigrant, founded it. As BART construction began in 1968, the business moved from where San Leandro BART is today, to its current location on Washington Avenue at 143rd Street. Riders on the BART line between San Leandro and Bayfair get an overview of our 2.5 acres from the west side of the train.
The business is now run by Sam Larsen (fourth generation), son of Harry Larsen, Jr., grandson of Harry Larsen, Sr., and great-grandson of Jens Larsen.

Sam was raised in San Leandro, and attended Broadmoor Preschool, Washington Elementary, Bancroft Junior High and San Leandro High. He received a finance degree from San Jose State University. Sam began running the business upon graduation and he and his family live in San Leandro. Sam's two sons, a niece and three nephews are all potential candidates for the fifth-generation to preserve the Larsen Lumber legacy.
Larsen Lumber is recognized as the fifth oldest continuous-owned lumberyard in the United States and has been successfully serving homeowners and contractors for 135 years.
