An accessory dwelling unit (ADU) is a secondary housing unit located on the same property as the primary residence, typically requiring its own entrance, kitchen, living space and bathroom facilities. Sometimes referred to as granny flats, cottages or studios, ADUs can take various forms including converted garages, basement apartments or standalone cottages.

Our standard building timeline right now is about four to eight months from design and permitting to completion. The most variable part of the total timeline is permitting and each city varies in terms of process. Contact us today to discuss your specific ADU project and timeline.

Pricing will vary depending on the size and features of the ADU. At Little Home Builders we strive to be at the intersection of quality and affordability with full-service project management to save time, pre-designed plans to create efficiencies of scale and transparency every step of the way. The price range to build an ADU in Colorado starts around $200k. Our pricing includes foundation, construction, elevation, finishes, design and engineering, permit submission and more. The variable costs that are not included are permit fees from the city or county and hookup fees. When we deliver an estimate, it will include a breakdown of all costs, including the variables so that you understand your total investment.

Modular and prefab ADUs are factory manufactured units or panels that are delivered to the property in-tact. Often fully modular units will encounter challenges with financing and appraisals as they are not generally considered real estate. Prefab units are an efficient solution, however, in addition to the unit price, additional costs that need to be understood include sales tax, shipping, site work, foundation, permitting and taps for sewer, water, electrical and gas, as well as crane installation. A side-by-side cost comparison usually reveals a comparable total investment for stick-built and prefab ADUs.
