A city adding houses rather than altering them
Roseville grew from 161,162 to 165,455 people over the year, a gain of 4,293. It added 2,106 homes, the sixth-largest increase of any California city, and 1,151 of them were single-family houses. That is about three of every five new homes in Placer County. The specific plans set the scale: the Sierra Vista Specific Plan, adopted in May 2010 for land west of Fiddyment Road, provides for 8,679 homes, and Amoruso Ranch, adopted on 15 June 2016, for another 2,827. So the typical Title 24 job here is a newly constructed house: a whole-building model of the proposed design, compared with a standard design for zone 11, with solar sized to the code. A remodel touches only what it alters; a new house is assessed entire.
Roseville Electric sets the solar ceiling
The city has run its own electric utility since 1912, and that utility has rules the energy report has to live with. Roseville Electric limits a home's solar array to 100 percent of its last twelve months of use. A new house has no history, so the limit is the conditioned floor area multiplied by 3 kWh a year. The Energy Code sets the floor and the utility sets the ceiling, and the array on the plans has to sit between them. SolarAPP+ covers only roof-mounted systems on a main dwelling, with Roseville Electric's pre-approval, and an electrical panel upgrade needs an application to the utility before the building permit is sought.
The county line is the zone line here
Rocklin, Granite Bay and Lincoln share Roseville's zone 11. Step over the Sacramento County line to the south and the assignment changes: Citrus Heights (95610 and 95621) and Antelope (95843) are zone 12. A builder with lots on both sides is working to two weather files.
Submitting to the Building Division
Applications go to the Development Services Department's Building Division electronically, through the Online Permitting Services portal, as PDFs with simple file names bookmarked by sheet. First plan review takes about three weeks and later rounds about two. Ordinance 6990 adopted the 2025 codes, Part 6 included, and amends only an electrical-service rule and pool enclosures. Even a reroof needs a signed CF1R for the current code cycle, on the city's own CF1R-ALT-01-E reroof form. The city received its State Fire Marshal hazard designations on 10 February 2025, and Ordinance 6949 designates its Moderate, High and Very High zones.
