Would this be a homeowners or car insurance claim?

I hit a garden wall. There's damage to both my car and the house. Would that be a home or car insurance claim?

While there are some details left it, the damage to the garden wall will be covered by your property damage liability insurance while the damage to your vehicle would be covered by your collision insurance. If it's your garden wall, you might have more freedom with the insurance proceedings. Otherwise, it will all be covered by your auto insurance.
