Which type of policy generally provides the least coverage for personal property?

The HO-1 policy, also known as a Basic Form homeowners policy, is designed to provide the least coverage among the types of homeowners insurance policies listed. It typically covers only specific perils that are specifically named in the policy, such as fire, lightning, and theft. This limited scope of coverage means that personal property is not as thoroughly protected compared to more comprehensive policies.

In contrast, the HO-2 policy (Broad Form) covers more perils than the HO-1, including additional risks such as falling objects and water damage from plumbing. The HO-3 policy (Special Form) offers even broader coverage, protecting against all perils except those explicitly excluded. The HO-4 policy is designed for renters and covers personal property but does not provide structural coverage, which does not directly relate to the specific context of homeowners policies.

Given these distinctions, the HO-1 policy indeed provides the least extensive protection for personal property, making it the correct answer.
