San Jose Remodel Budget Worksheet & Planning Checklist
Plan your remodel like a builder would. Set a realistic budget, divide it across the work, leave room for surprises, and walk into contractor conversations prepared. Print this, fill it in, and bring it to your free estimate.
Step 1: Set a realistic total budget
Start from honest San Jose planning ranges, then narrow as your scope firms up. These are 2026 ranges for the South Bay, pulled from our own cost guides. They are starting points to plan with, not quotes.
| Project | Cosmetic / standard | Mid-range | High-end / custom |
|---|---|---|---|
| Kitchen | Low–mid five figures | $40k–$70k | $90k–$180k+ |
| Bathroom | Low five figures | $20k–$35k | $40k–$60k+ |
| Whole home | $150–$200 / sq ft | $200–$350 / sq ft | $350–$500+ / sq ft |
| Detached ADU | $200k–$450k+ ($300–$500 / sq ft) | Up to ~$600k | |
| Garage conversion | $80k–$200k ($180–$350 / sq ft) | JADU from $50k–$150k | |

Step 2: Divide the budget across the work
Most remodels break down along similar lines. Use these typical shares as a sanity check, then write in your own numbers. Cabinetry and built-ins are usually the largest line in a kitchen; tile, waterproofing, and fixtures dominate a bathroom.
| Line item | Typical share | Your budget |
|---|---|---|
| Design, plans & permits | 5–15% | |
| Demolition & site prep | 5–10% | |
| Cabinetry & built-ins | 15–30% | |
| Countertops & surfaces | 8–15% | |
| Plumbing & fixtures | 8–15% | |
| Electrical & lighting | 5–12% | |
| Flooring & tile | 7–12% | |
| Appliances | 5–15% | |
| Paint & finishes | 3–8% | |
| Subtotal | ||
Shares are general planning guidance and shift with scope; moving walls, plumbing, or gas pushes the systems lines up. The biggest budget lever on any project is whether you keep your existing layout or relocate plumbing, electrical, and walls.
Step 3: Add a contingency (don't skip this)
Older San Jose homes routinely hide outdated wiring, plumbing, or framing that only shows up once walls open. Plan for 10–20% of your construction budget as a contingency so a surprise doesn't stall the job or force you to cut finishes you care about.
If the all-in number is more than you want to pay out of pocket, that's normal. Many South Bay homeowners spread the cost over monthly payments. See financing options and ask us about it at your estimate.
Permit & timeline checklist
In San Jose, most permitted remodels involve the same steps. Check these off as you plan. We handle all of them for our clients, but it helps to know what's coming.
Questions to ask any contractor
The right questions separate a builder who will protect your budget from one who won't. Bring this list to every bid conversation.
