Complete Guide to Whole-Home Remodeling in San Jose
San Jose is the largest city in the Bay Area and one of the most diverse whole-home remodeling markets in Silicon Valley. With housing stock ranging from 1940s bungalows in Willow Glen to 1970s tract homes in Almaden Valley and 1990s builds in Evergreen, costs and project complexity vary widely by neighborhood. Whole-home remodeling in San Jose costs $150-$300+ per square foot in 2026, making it more accessible than premium South Bay cities while still delivering high-quality results. The city's building department processes permits relatively quickly, and San Jose does not require design review for most single-family residential projects. This guide covers San Jose housing stock, project scope, costs, permits, timelines, and how to compare your options.
What should I know about whole-home remodeling in San Jose?
San Jose whole-home remodels cost $150-$300+/sqft in 2026, with most projects ranging from $300K to $900K+ depending on home size and scope. San Jose does not require design review for most residential projects, which streamlines the permitting process. Housing stock varies significantly by neighborhood, from 1940s bungalows in Willow Glen to 1970s ranches in Almaden Valley. Expect 6-14 months total from design through completion.
Why San Jose Is a Strong Market for Whole-Home Remodeling
San Jose is the third-largest city in California and the economic center of Silicon Valley. With over one million residents spread across dozens of distinct neighborhoods, San Jose offers one of the most diverse residential markets in the Bay Area. Median home prices range from under $1 million in some neighborhoods to well over $2 million in premium areas like Willow Glen and Almaden Valley.
For homeowners in established San Jose neighborhoods, whole-home remodeling offers a compelling value proposition. The cost of remodeling is lower than in smaller South Bay cities like Los Altos, Saratoga, and Palo Alto, while post-remodel home values in desirable neighborhoods often rival those premium markets. The city’s relatively streamlined permitting process and lack of design review for most residential projects make San Jose one of the easiest Bay Area cities to remodel in.
This guide covers San Jose’s housing stock by neighborhood, what whole-home remodeling includes, costs, permits, timelines, and how San Jose compares to other South Bay cities.
San Jose Housing Stock by Neighborhood
One of the most important factors in any whole-home remodel is the age, style, and condition of the existing home. In San Jose, housing stock varies significantly by neighborhood.
Willow Glen
Willow Glen is arguably San Jose’s most sought-after neighborhood for remodeling. The area features a mix of 1920s-1940s Craftsman bungalows, 1940s-1950s ranches, and some newer infill construction. Lot sizes range from 5,000 to 10,000+ square feet. The original homes are typically 1,000 to 1,800 square feet, making them strong candidates for expansion during a whole-home remodel. The neighborhood’s walkable downtown, mature tree canopy, and strong community identity make it an excellent investment for remodeling.
Rose Garden
The Rose Garden neighborhood features stately homes from the 1920s through 1950s, including many Colonials, Tudors, and Mediterranean-style residences. These homes are typically 1,500 to 3,000 square feet on generous lots. Remodeling in the Rose Garden often involves preserving the exterior character while completely modernizing the interior, systems, and layout.
Almaden Valley
Almaden Valley is a suburban community at the southern edge of San Jose, with most homes built in the 1970s and 1980s. Typical homes are 1,800 to 3,000 square feet on lots of 7,000 to 12,000 square feet. These homes are well-suited for whole-home remodeling because the structures are generally sound, lots are spacious, and the neighborhood commands strong resale values.
Cambrian
The Cambrian neighborhood features a mix of 1950s-1970s ranches and split-levels, typically 1,200 to 2,200 square feet. These homes are similar to what you find throughout the broader South Bay: functional but dated, with closed-off floor plans and aging systems. The Cambrian area offers good value for remodeling because lot sizes are reasonable and the neighborhood has excellent access to schools and amenities.
Evergreen and East San Jose
The eastern portions of San Jose feature newer construction from the 1980s through 2000s. These homes are often 1,500 to 2,500 square feet and are in better condition than older neighborhoods. Whole-home remodeling in these areas focuses more on cosmetic and layout updates rather than full systems replacement.
What Whole-Home Remodeling Includes
A whole-home remodel addresses every major element of the house in a single, coordinated project. In San Jose, the typical scope includes:
Systems upgrades: Electrical panel and wiring upgrades (200-amp service minimum), plumbing repipe, HVAC replacement, and water heater installation. Homes built before 1970 almost always need all four systems replaced.
Structural work: Foundation repairs or seismic retrofitting, load-bearing wall modifications for open floor plans, and any framing needed for layout changes. San Jose sits in an active seismic zone, and older homes were built to less stringent standards.
Kitchen renovation: Complete kitchen gut and rebuild. In San Jose’s competitive market, the kitchen is the single room that matters most for both livability and resale value.
Bathroom renovations: Updating all bathrooms, expanding the primary suite bathroom, and adding bathrooms where needed. Many older San Jose homes have a single bathroom or undersized secondary baths.
Interior finishes: New flooring, drywall, paint, trim, doors, lighting, and hardware throughout. The goal is a unified design from room to room.
Exterior work: Depending on the home’s condition, this may include roofing, siding, windows, doors, and landscape restoration.
Whole-Home Remodeling Costs in San Jose
Whole-home remodels in San Jose cost $150 to $300+ per square foot in 2026. Costs vary by neighborhood, home age, scope of work, and finish level.
All pricing is approximate, reflects 2026 Bay Area market conditions, and is subject to change. Every project is unique. Final costs are determined on a project-by-project basis during our design phase.
Cost by Scope
| Scope Level | Cost per Sqft | 2,000 Sqft Home |
|---|---|---|
| Cosmetic refresh (finishes, fixtures, paint) | $80-$150/sqft | $160,000-$300,000 |
| Mid-range (layout changes, systems upgrades) | $150-$275/sqft | $300,000-$550,000 |
| Gut renovation (structural, full systems) | $275-$400+/sqft | $550,000-$800,000+ |
What Affects Cost in San Jose
- Neighborhood: Willow Glen and Rose Garden projects trend toward the higher end because of market expectations and older housing stock. Evergreen and Cambrian projects are typically less expensive.
- Home age: Pre-1960 homes in Willow Glen may need foundation work, lead paint abatement, and asbestos removal, adding $20,000-$60,000+ to the project.
- Lot conditions: Homes on hillside lots in the Almaden foothills carry additional costs for grading, drainage, and retaining walls.
- Finish level: Mid-range finishes cost significantly less than the premium materials expected in Saratoga or Los Altos. San Jose homeowners have more flexibility in finish selection without sacrificing neighborhood compatibility.

Permits and Regulations in San Jose
Building Permits
The City of San Jose requires building permits for any structural, electrical, plumbing, or mechanical work. The city offers both online and in-person permit applications through the Planning, Building, and Code Enforcement Department.
San Jose has invested in streamlining its residential permit process in recent years. Plan review for a typical residential remodel takes 3-6 weeks. Express review may be available for simpler projects. The city also offers pre-application meetings to discuss project feasibility before you invest in full architectural drawings.
No Design Review for Most Projects
Unlike Los Altos, Palo Alto, and Saratoga, San Jose does not require design review for most single-family residential remodeling projects. This eliminates one of the most time-consuming steps in the pre-construction process and can save 2-4 months on your overall timeline.
Exceptions exist for properties in certain historic districts (such as parts of Naglee Park) and for projects that seek variances from standard zoning requirements.
Zoning and Setbacks
San Jose’s zoning code governs setbacks, lot coverage, building height, and floor area ratio. Most residential zones require 25-foot front setbacks, 6-foot side setbacks, and 20-foot rear setbacks, though this varies by zone. Your designer should verify the specific requirements for your property before beginning design work.
Historic Districts
Some San Jose neighborhoods have historic district protections. Naglee Park and portions of the Rose Garden area may have additional review requirements for exterior changes. Check with the city’s Historic Preservation Office if your property is within or adjacent to a designated historic district.

San Jose’s faster permit processing and lack of design review contribute to shorter overall timelines compared to cities like Los Altos and Palo Alto.
How San Jose Compares to Other Bay Area Cities
| City | Cost/Sqft | Permit Timeline | Key Difference |
|---|---|---|---|
| San Jose | $150-$300+ | 3-6 weeks | No design review, fastest permits |
| Cupertino | $175-$350+ | 4-8 weeks | Slightly higher costs, similar process |
| Campbell | $150-$300+ | 3-6 weeks | Comparable costs, smaller city |
| Los Altos | $200-$400+ | 6-14 weeks | Design review, story poles, higher costs |
| Saratoga | $200-$400+ | 4-12 weeks | Hillside regulations, heritage trees |
San Jose offers the most accessible entry point for whole-home remodeling in the South Bay. Lower per-square-foot costs combined with faster permitting make San Jose an excellent market for homeowners who want to maximize the impact of their remodeling budget.
Remodel vs. Build New in San Jose
For some San Jose homeowners, the question is whether to remodel the existing home or tear it down and build new. The decision depends on several factors:
Remodel makes sense when: The existing structure is sound, the foundation is adequate, the layout works with moderate modifications, and the total remodel cost stays below 50-60% of what a new build would cost. Most San Jose remodels fall into this category.
Building new makes sense when: The existing home is too small, the foundation has significant problems, the floor plan cannot be salvaged, or the remodel cost approaches $400+/sqft. At that point, a new custom build at $350-$500+/sqft gives you a completely new structure with modern systems, optimized energy performance, and full structural warranties.
