As part of the 2010 Denver Zoning Code update, Accessory Dwelling Units (ADUs) were again allowed by right in a select number of neighborhoods within the City and County of Denver. ADUs, or more historically accurate “Carriage Homes,” had been permitted in the distant past but were disallowed as the city’s culture shifted to a suburban and car-based economy and lifestyle after World War II. With the change in 2010-and the continued re-population and growth of our urban core-there has been a growing trend of ADU development. This option is helping homeowners and investors realize dreams to build income, expand their living space, or simply have a little extra room when family arrives, all while being much less disruptive to the neighborhood fabric than other types of development.
President of L&D Construction
Dave is a Colorado Native whose father has been a custom homebuilder in Colorado for 35 years. He formerly was a laborer and superintendent with Spanjer Homes (Fort Collins) from 2006-2009 and is a managing member of a family held real estate investment company.
In 2009, after getting married and moving to Denver, David started L&D Construction and began remodeling homes and building breweries throughout the urban core of Denver.
By 2015, it was clear that development and a booming population influx in Denver was here to stay for an extended period of time. As a way to add value and flexibility to his family’s lifestyle he decided to build an ADU in his backyard and then quickly realized there was real latent demand for these units in the Denver market, so in 2017 he created a segment of his business solely dedicated to this effort.
Sales Manager & Broker of L&D Construction
Sarah grew up in the Sangre de Cristo Mountains of southern Colorado. She was born into a real estate family with her Dad owning and operating a real estate business for over 35 years. She has been a Realtor in Colorado for 19 years and North Dakota for three years. Sarah worked with Conner Murphy Homes of Williston, ND from 2013-2016 selling and facilitating selections and design choices for over thirty new homes. She moved back home to Colorado in 2016 and saw an opportunity to join forces with L&D Construction and start building ADUs. She works with clients from the first idea of an ADU and throughout the entire construction process.
Sarah is very well versed in the nuances of the Denver Zoning Code regarding ADUs and is very adept at navigating the often-difficult city plan review and permitting process. Sarah is also philosophically a big proponent of smart development and feels that ADUs help keep existing neighborhoods intact while still increasing our much-needed housing stock.
