Craftsman bungalows and Queen Annes in Willow Glen, the Rose Garden, and Naglee Park; postwar tract homes out in Almaden Valley. Hand-vetted contractors for kitchens, baths, ADUs, and whole-home remodels.
San Jose's housing stock is unusually broad for one city. The older central neighborhoods, Willow Glen, the Rose Garden, Naglee Park, and Hensley, carry 1900s to 1930s Craftsman bungalows, Spanish and Mission Colonial Revival, Queen Anne Victorians, and Prairie homes, often with original built-ins and period detailing still intact. Almaden, Cambrian, Berryessa, and Evergreen lean the other way, toward 1950s to 1970s single-story tract and ranch housing, with Almaden Valley including larger homes on 8,000-plus square foot to one-acre hillside lots.
On the older tract homes, down-to-studs gut renovations are common where 1950s framing and 50-year-old systems need full replacement. We have matched contractors on San Jose projects across the valley floor and into the foothills, from kitchen openings and primary-suite additions to detached ADUs and full-scope renovations on homes families plan to keep for decades.

Realistic 2026 cost ranges based on the projects our contractors are actually pricing in San Jose right now.
The most requested project across San Jose. In the older Willow Glen and Rose Garden homes, the typical scope opens up a cramped 1920s kitchen, preserves period built-ins where they matter, and adds modern cabinetry, quartz or stone counters, and updated appliances. On 1950s to 1970s tract homes in Cambrian and Evergreen, we often relocate plumbing to support an island and open a wall into the living space.
Primary bathrooms in mid-century San Jose homes tend to be small with dated tub-shower combos. Most full-scope projects we see expand into an adjacent closet for a curbless walk-in shower, double vanity, and updated tile. Hall-bath refreshes run the lower end of the range.
San Jose runs a pre-approved ADU program widely cited as the most homeowner-friendly in the Bay Area. Homeowners pick a standardized plan already reviewed by city staff, and a site-specific permit can be issued the same day as the plan-review meeting. Detached units anchor the higher end of the range, while garage conversions typically run lower.
Browse ADU models →Common for owners of 1950s ranches and 1920s bungalows who want a second story, a primary suite, or a full down-to-studs rebuild. On older homes the scope usually includes replacing electrical, plumbing, HVAC, and insulation alongside the cosmetic work. Larger Almaden Valley homes on hillside lots land at the top of the range.
Permits run through the City of San Jose Planning, Building and Code Enforcement Building Division, served at the Development Services Permit Center at 200 E. Santa Clara St., 1st Floor (City Hall Tower). The city publishes plan-review time frames in working days: about 10 for a single-story addition or a non-structural alteration, 15 for a two-story addition, and 20 business days for the first round on an ADU, with shorter rechecks after that. The city currently asks applicants to add 2 to 3 weeks because of application volume, and its own guidance is to aim to stay within one or two review cycles. San Jose also offers an in-person Over-the-Counter service for qualifying single-family and duplex projects with no appointment, plus a virtual Residential Express service for qualifying projects under 500 square feet.
Several central neighborhoods carry preservation oversight. The Hensley City Landmark District (HD89-51) is also a National Register district of 279 properties, and Naglee Park is a designated Campus Community Conservation Area, part of San Jose's seven Conservation Areas. Work in these areas can route through the San Jose Historic Landmarks Commission or PBCE Planning Division historic preservation staff, so your contractor should confirm the designation before scoping exterior changes.
Portions of San Jose, primarily the East Foothills and Almaden Valley hillside areas, fall within California's High and Very High Fire Hazard Severity Zones, while valley-floor neighborhoods do not. Homes in those zones trigger Chapter 7A ignition-resistant exterior assemblies on additions and major remodels, plus defensible-space requirements. On older pre-modern-code homes, foundation bolting, cripple-wall shear paneling, and hillside pier upgrades are common bid-day adders, roughly $15K - $60K depending on scope, given the Calaveras, Hayward, and San Andreas faults nearby.
