Homeowners policies provide six main types of coverage, labeled A-F. Other minor coverages are often written into the policy. Coverages are typically based on dwelling coverage. For example, coverage B (detached structures) is limited at 10% of dwelling coverage. If a dwelling coverage is $200,000, then detached structures are covered for $20,000 (10% of $200,000). HO3 is the most common type of homeowners policy, therefore we will use HO3 coverage limits as examples.
