You simply need to be navigated through the process and  Core Contractors can.  Furthermore, we can now incorporate the seismic retrofitting requirements into the ADU design.

Of most projects your building undertakes, none will return your investment faster than an Accessory Dwelling Unit (ADU) when properly evaluated and designed to maximize efficiency of space and minimize the cost of construction with numerous value engineering (VE) techniques. Only a seasoned 40+ years general contractor such as Core Contractors can. Often within a 3 year period, your investment in the ADU will be repaid in added rent-roll alone and that rent continues to pay forever. Your property value also increases which makes the investment in ADU’s easy to make. Feel free to use our ADU ROI calculator or contact us for a no obligation site evaluation. 


At Core Contractors we focus on multifamily applications related to ADUs, not single homes. Several cities have developed an ADU program due to a notable housing shortage. The program differs slightly between the cities but they all offer a shortened process to approval with less issues, less compliance, fast turn-around. Most building should consider an increase of 25% to your existing unit count. Added units do not need to provide added parking for the added ADUs… moreover,  Building can use the current parking spaces for the location of the new ADUs without replenishment. No fire sprinkler requirements, limited ADA compliance needed, 60 day city approval commitment… you get the idea? It’s a gift that you should accept because it won’t last forever. 


The designers of Core Contractors have developed a cost efficient design for converting a 2, 3, and 4 car spaces into ADU’s, the design is pre-priced to include all required work with a level of pre-selected finishes at a lump sum price. If required we also include the seismic retrofit required for Soft Story conditions into the design. By far the most cost efficient way to comply with seismic retrofitting is by adding an ADU to your parking level. 


As always, Core Contractors utilizes an in house staff of professionals to serve the needs of a project from initial client contact through design, plan-check and permitting process, construction, and final C of O.
