How Much Do Construction Projects Cost in Danville, Alamo & Pleasanton?
A Realistic Cost Guide for Kitchens, Bathrooms, Whole House Remodels & ADUs
One of the first questions every homeowner asks is: “How much is this going to cost?”
It’s a fair question—and an important one.
After nearly 40 years of remodeling homes in Danville, Alamo, Pleasanton, and Lafayette, we’ve found that the best way to answer that question is to provide realistic ranges, explain what drives costs, and help homeowners understand what makes sense for their goals.
Below is a breakdown of typical project costs based on our experience.
🏗️ Bathroom Remodeling Cost
Typical Range:
• Guest Bathroom: $35,000 – $65,000
• Primary Bathroom: $65,000 – $125,000+
What Impacts Cost:
• Tile selection and layout complexity
• Plumbing relocation
• Custom cabinetry and vanities
• Glass enclosures and specialty fixtures
Bathrooms are smaller spaces, but they are detail-heavy and labor-intensive, which is why costs can add up quickly.
🍽️ Kitchen Remodeling Cost
Typical Range:
• Basic Kitchen Remodel: $75,000 – $125,000
• Mid-Range Remodel: $125,000 – $200,000
• High-End / Structural Remodel: $200,000 – $350,000+
What Impacts Cost:
• Removing or relocating walls (structural work)
• Cabinet quality and layout
• Appliance package
• Countertops and backsplash materials
• Electrical and lighting upgrades
Many kitchens in older East Bay homes require structural changes to open up the space, which is often where costs increase—but also where the biggest transformation happens.
🏠 Whole House Remodeling Cost
Typical Range:
• Light Remodel: $150 – $250 per sq ft
• Major Remodel: $250 – $400+ per sq ft
What Impacts Cost:
• Age and condition of the home
• Structural modifications
• Electrical, plumbing, and HVAC upgrades
• Level of finish throughout the home
Whole house remodeling allows you to transform your entire home at once, often creating better long-term value than remodeling room by room over time.
➕ Additions & ADU Cost
Typical Range:
• Home Additions: $300 – $500+ per sq ft
• ADUs (Accessory Dwelling Units): $250,000 – $500,000+
What Impacts Cost:
• Site conditions and access
• Foundation and structural requirements
• Utility connections
• City permitting and impact fees
• Level of finish and design complexity
Additions and ADUs are essentially building a new structure, which is why costs are higher than interior remodeling. However, they also add significant usable space and long-term value.
💡 Why Costs Vary So Much
No two homes—and no two homeowners—are the same.
In established neighborhoods like Danville, Alamo, Pleasanton, and Lafayette, cost variations are often driven by:
• Older construction methods
• Previous remodels
• Structural challenges
• Material selections
• Permit requirements
This is why online “average costs” can be misleading.

• A clear scope
• Realistic expectations

One of the biggest mistakes homeowners make is spending money in areas that don’t add value.
We guide clients toward:
• Structural improvements that enhance layout
• High-impact design features
• Long-lasting materials

The goal is not just to spend money—it’s to spend it wisely.
