ADU (accessory dwelling unit)

Coverage Types

An Accessory Dwelling Unit (ADU) is a secondary, self-contained residential unit located on the same parcel as a primary single-family dwelling. ADUs — also known as in-law units, granny flats, or backyard cottages — present unique insurance considerations. Depending on whether the ADU is attached or detached, owner-occupied or tenant-occupied, it may be covered under the primary homeowners policy's dwelling (Coverage A) or other structures (Coverage B) provisions, or it may require a separate dwelling fire or landlord policy.

Blanket Coverage

Coverage Types

A single insurance policy that covers multiple properties, locations, or categories of property under one combined limit, rather than assigning separate specific limits to each.

Claims-Made vs Occurrence

Policy Terms

Two types of liability insurance policy trigger mechanisms. An occurrence policy covers incidents that happen during the policy period, regardless of when the claim is later filed. A claims-made policy only covers claims that are both reported during the active policy period and that occurred after the policy's retroactive date. Claims-made policies require continuous coverage or a tail (extended reporting period) policy to maintain protection for past acts.

Policy Terms

A dwelling fire policy (DP policy) is a property insurance policy designed for residential structures that do not qualify for a standard homeowners policy — most commonly tenant-occupied (landlord-owned) properties, vacant homes, or properties under renovation. Dwelling fire policies come in several forms (DP-1, DP-2, DP-3), offering progressively broader coverage. Unlike a homeowners policy, a standard dwelling fire policy does not include personal liability or personal property coverage for the owner, though these can sometimes be added by endorsement.

Loss Assessment Coverage

Coverage Types

Coverage that pays for a policyholder's share of a loss assessment charged by a homeowners association (HOA) or condo association when a covered peril damages common areas or when the association's master insurance policy is insufficient to cover a loss.

Zach’s take included

Secondary Home

Policy Terms

A secondary home (also called a second home or vacation home) is a dwelling that the owner occupies for part of the year but is not the primary residence. Insurers distinguish secondary homes from primary residences and rental properties because occupancy patterns affect risk. Secondary home policies may carry higher premiums or different underwriting requirements, and carriers typically require that the home not be rented out for more than a specified number of days per year to qualify for secondary home rather than landlord or rental dwelling coverage.

Zach’s take included

Short Term Rental

Policy Terms

A short-term rental is a residential property rented to guests for periods typically less than 30 days, often through platforms such as Airbnb, Vrbo, or similar services. Standard homeowners policies generally exclude or severely limit coverage for properties used as short-term rentals because the transient occupancy increases liability exposure and property damage risk. Owners may need a specialized short-term rental policy, a landlord policy, or a specific endorsement to maintain proper coverage. Host platform liability programs (e.g., Airbnb's AirCover) provide limited protection but are not a substitute for a comprehensive insurance policy.

Zach’s take included

SR-22

Legal & Compliance

A certificate of financial responsibility filed by an insurance company with the state DMV on behalf of a driver, proving that the driver carries at least the state-required minimum auto insurance. Typically required after serious traffic violations such as DUI, driving without insurance, or accumulating multiple at-fault accidents.

Zach’s take included

Subrogation

Claims

The legal right of an insurance company to pursue a third party that caused a loss to the insured in order to recover the amount paid on the claim. This prevents the insured from collecting twice for the same loss.

Zach’s take included

Surplus Lines (E&S)

Risk & Underwriting

Surplus lines insurance (also called Excess & Surplus or E&S) refers to coverage placed with non-admitted carriers — insurers not licensed in the state where the risk is located but authorized to write business through surplus lines regulations. E&S carriers are used when the standard (admitted) market is unwilling or unable to provide coverage due to the nature, size, or risk profile of the exposure. Unlike admitted carriers, E&S insurers are not backed by state guaranty funds, and their rates and forms are not subject to prior approval by state insurance departments, giving them greater flexibility in pricing and policy design.
