My tenant’s guests use the dock. Am I liable?
You can be, and usually are named. Owner responsibility for a fixed structure does not pass to a tenant with the keys. That is why a waterfront rental warrants a higher liability limit than an inland one, and often an umbrella above it.
Will carriers insure a rental with a dock?
Some will and several restrict or exclude structures over water, more so on a rental. It is worth confirming before buying a waterfront property to rent out, because the market is narrower than for the house alone.
Does short-term renting change it?
Considerably. More people, more turnover and a commercial character mean a different product than a standard landlord policy. We will tell you which one the property actually needs.
