“Plan-It Paramount” – Pre-Approved Plans
The City of Paramount is proud to announce the launch of the ADU Program – “Plan-It Paramount” offering several pre-approved ADU plans for homeowners in Paramount ranging in size from studios to three-bedroom units. The City is launching this program by offering four plans that have been pre-reviewed, preapproved by the Building and Safety Division resulting in time-saving in both the design and permitting of an ADU. There will be several more plans added to the program in the coming months, which are designed by licensed professionals, providing additional options to residents.
Note: Modifications or customizations to pre-approved ADU plans are not allowed, regardless of how minor the changes are. While some site-specific design work may be required, Plan-It Paramount aims to significantly reduce pre-construction costs for property owners looking to build an ADU. Plans that are designed by the City are available at no cost.
