Each listing on the Plans Gallery includes cost information, provided by the designer. Note: ADU Accelerator is not responsible for this content or any real-world deviation from these estimates.
Listings include the following fields:
Cost to use a plan #
Site-built ADU listings have an associated cost to use the plan. This is the cost to buy the plan with no customization or additional services from the designer. Because plans on the Plans Gallery are not specific to your property, every ADU project requires additional work before permitting applications can be submitted. For instance, a professional will need to supply the information about how your ADU fits into your property – showing the required space between the ADU and your property lines, how utilities connect the unit, and a lot of other details. This can be done either by the designer of the plan, if they are available for work in your area, or by a professional you’ve hired separately.
Prefabricated ADUs do not have an associated plan cost, because it is included in the total unit cost.
Construction cost estimate #
Each listing includes an estimated range for construction costs, provided by the designer. See Estimating Construction Costs for more details.
Additional Cost Notes #
This is additional information provided by the designer about the cost to use the plan and/or the construction cost estimates. You are welcome to ask the designer clarifying questions if you are buying a plan, but some designers might consider detailed cost estimation a support service and want to charge a consultation fee.
