Does, "... gas, electricity, and any other costs associated with the internet," mistakenly imply gas and electricity as a cost for internet?

Solution 1:

You are correct that this internet appears to be quite the resource hog; as it is written here, costs is common to each item in the list:

Tenants shall be responsible for gas [costs], electricity [costs], and any other costs associated with the internet.

However, simply removing other doesn’t entirely fix the problem:

? Tenants shall be responsible for gas, electricity, and any costs associated with the internet.

Does this mean they have to, say, bring their own gas and electricity, and pay for supplied internet?

Try:

Tenants shall be responsible for gas, electricity, and internet costs.
