What this means

1. Accessory Dwelling Unit (ADU) Ordinance Update 2026, File # PL26-0134
The project is a request to amend Roseville Municipal Code Chapter 19.60 (Accessory Dwelling Unit Ordinance) and amend Roseville Municipal Code Section 19.10.030 to update and reorganize the City’s Accessory Dwelling Unit (ADU) Ordinance. Key changes include updating multiple sections to reflect legislation passed in 2025, including changing square footage limitations to be based on square footage of livable space, adding a definition for livable space, revising the number of ADUs permitted to reflect that any combination of permitted units is allowed, revising the Residential Zone General Development standards table of Roseville Municipal Code Section 19.10.030 to refer to Chapter 19.60 instead of stating the number of ADUs permitted, and limiting the owner occupancy requirement for a Junior ADU to cases where sanitation facilities (bathrooms) are shared. Additional changes include eliminating the Administrative Permit process allowing deviations from standards, adding references to the definition of “kitchens” found in Roseville Municipal Code Chapter 19.95, a new definition for "separate entrance" and "separate exterior entrance," and other changes to improve readability and clarity. | attachments=3 | reports=1
