Accessory Dwelling Units (ADUs)—also known as granny flats, in-law units, or backyard homes—are rapidly growing across Orange County, CA.
But here’s what most homeowners don’t realize:
👉 Your standard home insurance may NOT fully cover your ADU.
If you own or are building an ADU in Orange County, this guide will show you how to properly insure it, avoid costly mistakes, and protect your investment.
âś… What Is ADU Insurance?
ADU insurance refers to properly structuring your policy to cover:
- The ADU structure
- Liability risks
- Rental income (if applicable)
Depending on your situation, this may be:
âś” Homeowners policy (HO3) with endorsements
âś” Landlord insurance policy (VERY common)
âś” Dwelling/fire policy for rental properties
👉 The key is making sure your ADU is declared and correctly rated.
🏠Do You Need Special Insurance for an ADU?
Yes—especially if your ADU is:
âś” Detached from your main home
âś” Rented out to tenants
âś” Used for Airbnb / short-term rental
âś” Generating income
🚨 If your insurance company doesn’t know about your ADU, your claim could be denied.
🛡️ What Does ADU Insurance Cover?
🔥 Property Protection
- Damage to the ADU structure
- Fire, storms, vandalism
⚖️ Liability Coverage
- Injuries to tenants or guests
đź’° Loss of Rental Income
- Covers lost rent if the unit becomes uninhabitable
🧱 Other Structures
- Shared areas, garages, fencing
⚠️ Common ADU Insurance Mistakes
Avoid these costly errors:
đźš« Not informing your insurance company about the ADU
đźš« Renting it out under a standard homeowners policy
đźš« Not increasing liability limits
đźš« Using the wrong policy type
👉 These mistakes can lead to denied claims or major financial loss.
đź’° How Much Does ADU Insurance Cost in Orange County?
Costs depend on:
- Size and value of the ADU
- Rental vs personal use
- Location and risk factors
- Coverage limits
đź’¸ Typical Cost Range:
- $300 – $1,800+ per year (adjustment or separate coverage)
👉 Rental ADUs typically require landlord-style coverage, which may cost more—but offers stronger protection.
📉 How to Save on ADU Insurance
âś” Bundle with your main home policy
âś” Install safety features (smoke detectors, alarms)
âś” Maintain a clean claims history
âś” Work with an independent insurance broker
