Quick Answer
Earthquake retrofitting is generally not tax-deductible as a home improvement expense. However, if retrofitting qualifies as a medical necessity due to disability, portions may be deductible as medical expenses. In 2026, medical expenses exceeding 7.5% of your adjusted gross income are deductible.

Can earthquake retrofitting be tax-deductible?
Unfortunately, earthquake retrofitting expenses are typically not tax-deductible for most homeowners. The IRS classifies seismic retrofitting as a capital improvement to your home, similar to installing new windows or upgrading electrical systems. According to IRS Publication 523, capital improvements increase your home's basis but cannot be deducted in the year you make them.
Example: $25,000 retrofitting project
Let's say you spent $25,000 on earthquake retrofitting that included:
This entire $25,000 gets added to your home's cost basis. If you originally bought your home for $400,000, your new basis becomes $425,000. This means when you sell your home, you'll pay capital gains tax on less profit — but you get no immediate tax deduction.
When retrofitting might be deductible
Medical necessity exception
Retrofitting expenses can be deductible if they qualify as medical expenses under IRS rules. This applies when:
For 2026, medical expenses exceeding 7.5% of your adjusted gross income (AGI) are deductible if you itemize.
Example: Medical necessity deduction
Sarah has mobility issues and her doctor recommends retrofitting to prevent injury during earthquakes. Her situation:
Key factors that determine deductibility
What you should do

Medical necessity opens the door to deductions
If you or a family member has a disability that makes earthquake retrofitting medically necessary, you may be able to deduct these expenses. The IRS allows medical expense deductions for home improvements that are "primarily for medical care."

To claim this deduction, you need:
Example calculation
Mark spends $18,000 on retrofitting prescribed for his wife's mobility issues:
This saves Mark approximately $3,075-$4,920 in taxes depending on his tax bracket.

Planning retrofitting as a new homeowner
As a first-time homeowner, it's important to understand that earthquake retrofitting is an investment in your home's value and your safety — but not a tax write-off in most cases.
Smart timing strategies
Before you buy: If possible, negotiate retrofitting into the purchase price. This increases your initial basis without requiring separate documentation.
After purchase: Document everything meticulously. Even though you can't deduct retrofitting expenses immediately, they reduce your taxable gain when you sell.
Cost basis impact example
You buy a home for $550,000 and spend $20,000 on retrofitting:
Consider local incentives
While federal tax deductions aren't available, many earthquake-prone areas offer:
Check with your city and county for programs that offset retrofitting costs.
Record-keeping essentials
Key takeaway: New homeowners should view retrofitting as a long-term investment that increases home basis and may qualify for local incentives, even without federal tax deductions.
Key Takeaway: First-time homeowners should focus on local incentives and long-term basis increases rather than immediate federal tax deductions for retrofitting.
