The biggest housing news in Roseville this week was the City Council’s final vote on May 20 to rewrite the city’s rules for Accessory Dwelling Units (ADUs) — the smaller secondary homes residents can build on the same lot as their main house, like a backyard cottage, a converted garage, or an in-law unit above a detached garage. The action was the second reading of the ordinance, the formal final vote that follows an earlier preliminary approval, and it amends Chapter 19.60 and Section 19.10.030 of the city’s zoning code. For homeowners, this matters in practical terms: the updated chapter governs how big an ADU can be, how close to property lines it can sit, what parking is required, and whether a separate hearing is needed before building. Because the ordinance has now had its second reading, the new rules take effect in roughly 30 days, meaning property owners considering a rental cottage or a unit for an aging parent will be applying under the revised standards by early summer.
Also on May 20, the council approved a parcel map for Parcel WB-30 inside the Sierra Vista Specific Plan — the city’s long-planned new neighborhood on the west side of Roseville, roughly between Fiddyment Road and Westbrook Boulevard, which is being built out in phases with thousands of homes. A parcel map is the legal document that formally divides a larger piece of land into smaller, individually buildable lots, and approval is typically one of the last administrative steps before construction crews can begin work on a specific block. For future buyers in Sierra Vista, the WB-30 approval means another section of the master-planned community is now cleared to move from paper to graded lots, adding to the steady pipeline of new homes coming online in that part of the city.
On a much smaller scale, the Planning Commission on May 28 signed off on the Pleis Addition, an administrative permit allowing a two-story addition to the single-family home at 161 S Lincoln Street, in the older grid of streets near downtown. An administrative permit is a streamlined approval used for projects that meet the city’s standards but need a sign-off because of factors like the home’s age, size, or location in an established neighborhood. The Infill Parcel 32A designation flags it as a small lot inside the already-developed part of the city rather than a new subdivision. For neighbors, the practical effect is straightforward: one nearby house will get larger, with a second story added on, but no new lots or units are being created.
What’s coming up: with the ADU ordinance now final, attention will turn to how quickly homeowners file applications under the new rules, and to the next round of parcel maps expected from Sierra Vista as additional blocks come forward for approval later this summer.
