Simi Valley, in the western Simi Hills of Ventura County, is a bedroom community with strong ties to the Los Angeles employment market via the 118 Freeway. The city has a significant population of families drawn by more affordable home prices (relative to LA County), good schools, and lower crime — and an active renovation market as a result.
Simi Valley's Housing Stock
The dominant housing type in Simi Valley is post-1960s planned development. Most homes date from the 1960s–1990s, with significant tracts from each decade. This means the "bones" of most homes are generally sound — post-war construction with conventional framing, in many cases newer than comparable Valley homes — but the finishes and systems reflect their age.
Original kitchens from the 1970s–1980s are among the most common renovation targets. These homes often have U-shaped or galley kitchens with limited storage, dated finishes, and appliances that are past their service life.
Renovation Activity in Simi Valley
Simi Valley sees strong renovation demand across all categories:
Kitchen renovations: The most common project. Mid-range kitchen renovation costs in Simi Valley: $40,000–$80,000 for a quality result.
Bathroom renovations: Hall bath: $12,000–$24,000. Primary bath: $22,000–$45,000.
Room additions: Simi Valley's lot sizes support additions in many neighborhoods. Primary suite additions, family room expansions, and garage conversions to ADUs are all viable.
Full home updates: Many Simi Valley homeowners are doing comprehensive updates — new windows, HVAC, flooring, kitchen, baths — as a single project rather than piecemeal work.
Simi Valley Permits
Simi Valley has its own Building and Safety Department, separate from both LA and Ventura County. The city generally has faster plan check turnaround than LADBS — standard plan check runs 3–6 weeks for residential renovation projects.
Fire hazard note: Parts of Simi Valley, particularly northern areas near open hills, fall within Very High Fire Hazard Severity Zones. The Easy Fire (2019) affected some Simi Valley neighborhoods. VHFHSZ properties have additional requirements for exterior renovation materials.
