Homeowners across the country ask this question every day. And the honest answer is: it depends. But you deserve more than that. How much does it cost to renovate a house? On average, expect to spend between $100 and $400 per square foot. A full home renovation cost typically falls between $150,000 and $300,000 or more.
The real number depends on your home’s size, where you live, and how deep the work goes. In this guide, you’ll see real cost breakdowns, room-by-room pricing, San Diego-specific figures, and a step-by-step way to estimate your own budget.

Average Cost to Renovate a House (2026 Updated)
Cost Per Square Foot
Home remodel cost per square foot ranges from $15 to $150 nationally for basic work. For real contractor-level projects the kind that actually transform a home expect $100 to $400 per square foot.
Here’s why the gap is so wide: a cosmetic refresh (new paint, flooring, fixtures) costs far less than opening walls, moving plumbing, or adding square footage.
Total Renovation Cost by Level
Renovation Level | Estimated Total Cost |
Basic (cosmetic only) | $50,000–$90,000 |
Mid-range | $100,000–$250,000 |
High-end / Luxury | $250,000–$500,000+ |
Most homeowners spend between $100,000 and $300,000 to renovate a house.
Renovation Cost Breakdown by Home Size
Full house renovation cost scales directly with square footage. Here’s what to expect:
Home Size | Estimated Cost Range |
1,000–1,500 sq ft | $100,000–$300,000 |
1,500–2,500 sq ft | $150,000–$500,000 |
2,500+ sq ft | $300,000–$800,000+ |
Larger homes cost more but not always proportionally. Kitchens and bathrooms drive costs regardless of home size.
Real Cost Examples (What You Actually Get)
This is the section most guides skip. Here are three real-world scenarios:
$75,000 Renovation: Cosmetic Upgrade Paint throughout, new flooring, updated fixtures, and fresh cabinetry hardware. No structural changes. No plumbing moves. This is a surface-level refresh that improves appearance and feel.
$200,000 Renovation: Kitchen, Bathrooms + Partial Layout Full kitchen gut with new cabinets, countertops, and appliances. Two bathroom remodels. Some electrical upgrades. Possibly removing a non-load-bearing wall. This is where most mid-range home renovation costs land.
$500,000+ Renovation: Full Gut Remodel Everything. New systems (HVAC, plumbing, electrical). New layout. High-end finishes throughout. Custom kitchen. Multiple bathrooms. If you’re asking how much does a home renovation cost at the luxury level this is it.
Cost to Renovate by Room
Kitchen Renovation Cost
The kitchen is the most expensive room in any home. A mid-range kitchen remodel runs $25,000 to $75,000. A high-end custom kitchen can hit $100,000 to $150,000 or more. New cabinets, countertops, appliances, and layout changes all push costs up fast.
Bathroom Renovation Cost
A standard bathroom remodel costs $10,000 to $30,000. A primary suite bathroom with a walk-in shower, soaking tub, and tile work can reach $40,000 to $50,000+. If you’re thinking about whether you need a permit to remodel a bathroom, the answer in most cities including San Diego is yes, especially if plumbing moves.
Want to upgrade your soaking area? Learning how to fit a freestanding tub in a small bathroom can save layout costs while adding a luxury feel. Small choices like choosing to replace a bathroom faucet instead of full fixture replacement cut costs without sacrificing results.
Living Room and Bedroom
These rooms run cheaper: $5,000 to $30,000 depending on finish level. Flooring, lighting, and paint are the biggest line items. Black and white bathroom ideas and neutral tones also work beautifully in living spaces and cost less than bold tile or custom millwork.
Whole House Renovation
The entire home renovation cost runs $150,000 to $600,000+. The average home renovation cost for a full gut remodel in most U.S. metro areas is around $200,000 to $350,000.
House Renovation Cost in San Diego
San Diego is one of the most expensive renovation markets in the country. If you’re planning a project here, national averages won’t give you an accurate number.
Cost Per Square Foot in San Diego
Expect to pay $150 to $400+ per square foot for a mid-range to high-end remodel. Home remodeling cost here is 20–35% higher than the national average.
Full Home Cost in San Diego
A full home renovation cost in San Diego typically runs $200,000 to $600,000+, depending on scope and finishes.
Why Costs Are Higher in San Diego
Three main reasons push renovating costs up locally:
- Labor rates: Skilled tradespeople charge more in San Diego than in most other cities.
- Permits: The City of San Diego requires permits for most structural, electrical, and plumbing changes. Fees and inspection timelines add to the total.
- Material demand: Coastal homes often require moisture-resistant materials, which cost more.

What Affects the Cost of Renovating a House?
1. Size of the Home
Bigger homes cost more. Simple.
2. Scope of Work
Cosmetic updates are far cheaper than structural changes. The price for renovation homes jumps sharply when walls move, plumbing relocates, or new additions go up.
3. Material Quality
Basic materials keep the budget for home renovation down. Mid-range to luxury finishes add 30–60% or more to material costs alone.
4. Labor Costs
Labor typically makes up 40–50% of your total home remodel cost. In high-demand markets like San Diego, that percentage can be even higher.
5. Structural Changes
Opening walls, adding windows, moving load-bearing elements these require engineers and inspectors. They add real money.
6. Permits and Regulations
Permits aren’t optional. They protect you legally and ensure safe work. In San Diego, permit fees alone can run $2,000 to $10,000+ depending on project scope.
Hidden Costs Most Homeowners Ignore
This is where budgets break.
Permits and inspection fees are often left out of early contractor quotes. Ask upfront.
Plumbing and electrical upgrades come up mid-project. Older homes almost always need panel upgrades or repiping once walls open.
Mold and structural damage discovered mid-renovation can add $5,000 to $30,000 to your budget sometimes more.
Delays and material price changes in 2026 are still a real factor. Supply chain costs haven’t fully stabilized. Build a 15–20% buffer into every estimate.
The cost of renovating a house almost always exceeds the first quote. Plan for it.
Renovation vs Remodel Cost
These two terms get confused constantly. Here’s the difference:
Renovation means updating what already exists, new finishes, updated fixtures, and fresh paint. It keeps the structure the same.
Remodel means changing the structure or layout, moving walls, adding rooms, and reconfiguring floor plans.
Remodels cost significantly more. If you’re comparing house renovation price quotes from different contractors, make sure you know which type they’re pricing.
Is It Cheaper to Renovate or Buy a New House?
Situation | Better Option |
Good structure, dated finishes | Renovate |
Major structural issues | May be cheaper to buy new |
Strong emotional attachment to home | Renovate |
High-cost market (like San Diego) | Depends on purchase price vs home renovation cost |
Renovation wins when the bones are good. Buying new wins when structural problems would make renovation cost more than the home is worth.
How to Estimate Your Renovation Cost (Step-by-Step)
Step 1: Measure your total square footage.
Step 2: Decide your renovation level basic, mid-range, or full gut.
Step 3: Multiply square footage by cost per sq ft. Example: 1,800 sq ft × $200 = $360,000.
Step 4: Add a 15–20% buffer for hidden costs and price changes.
This gives you a working budget for home renovation before you talk to a single contractor.
How to Save Money on House Renovation
Keep your existing plumbing layout. Moving pipes is one of the fastest ways to inflate the home remodeling cost.
Choose mid-range materials. You get 80% of the look at 50% of the cost compared to luxury finishes.
Renovate in phases. Tackle the kitchen one year, bathrooms the next. Spreading projects reduces financial strain.
Get at least three contractor quotes. Home renovation costs vary widely between contractors sometimes by 30% or more for the same scope.
Timeline of a House Renovation
Scope | Estimated Time |
Small cosmetic | 1–3 months |
Medium (kitchen + baths) | 3–6 months |
Full gut remodel | 6–12+ months |
Permits add time. In San Diego, permit approval alone can take 4–8 weeks.
When Should You Renovate Your House?
Before selling: targeted renovations can increase resale value by 10–20%. Kitchen and bathroom updates offer the best return.
After buying a fixer-upper: address structural and system issues first, cosmetic upgrades second.
When your layout no longer works: growing families, aging in place, or remote work needs often make a remodel necessary even without plans to sell.

FAQs About Home Renovation Cost
How much does it cost to renovate a 1,500 square foot house?
A 1,500-square-foot house costs $15,000 to $30,000 for minor cosmetic work, $30,000 to $75,000 for a moderate renovation covering key rooms, and $75,000 to $150,000+ for a complete high-end overhaul. The average remodel cost per sq ft for this size ranges from $25 to $100 depending on scope and finishes.
What is the most expensive part of renovating a house?
Kitchens and bathrooms are the most expensive rooms to renovate because they involve plumbing, electrical, and cabinetry. Structural changes like removing load-bearing walls or adding square footage are also major cost drivers. Labor typically makes up 30% to 50% of total renovation project costs.
Is it cheaper to renovate or build new?
Renovating is almost always cheaper than building new. New construction costs $150 to $400+ per square foot including land. Renovation runs $50 to $200 per square foot in most markets. The exception is a home with severe structural damage at that point, the complete house renovation cost can approach new construction pricing.
Do I need permits for home renovations?
Most structural changes, electrical work, plumbing modifications, and additions require permits. Cosmetic updates like painting or replacing fixtures typically don’t. Always check with your local building department before starting work. Working without required permits creates serious problems at resale and may affect your homeowner’s insurance.
How do I finance a home renovation?
The most common options are home equity loans, HELOCs, personal loans, and cash-out refinancing. Home equity loans and HELOCs offer the lowest interest rates because they’re secured by your home. Personal loans work for smaller projects. The right choice depends on how much equity you have and the size of your renovation project.
What renovations add the most value?
Minor kitchen remodels return 70% to 80% of their cost at resale. New garage doors return 90% to 95% the highest ROI of any single upgrade. Bathroom renovations return 60% to 70%. Curb appeal projects like landscaping and exterior painting nearly always pay for themselves because they’re affordable and highly visible to buyers.
