The correct answer is that "Off premises sign coverage up to $2,500" is not a coverage extension typically found in the Building and Personal Property Coverage form. This form is designed to provide coverage for a variety of property-related risks but specifies different types of coverage rather than general extensions for signs off the premises.
Using this context, other coverage extensions listed, such as coverage for tenant's improvements, newly acquired property, and extended business income, are all standard coverages that can be found within the Building and Personal Property Coverage form. Tenant’s improvements cover alterations made to the rented space that enhance its value. Newly acquired property coverage offers protection for property that is purchased after the policy is in effect, ensuring that recent investments in property are covered. Extended business income coverage provides an extension for loss of income during the period required to resume full operation after a covered loss.
In summary, while the other options reflect valid and recognizable extensions of coverage within this insurance form, off-premises sign coverage is generally not included, making it the correct choice as the exception.
