ADU (accessory dwelling unit)
Coverage TypesAn 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.

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.
Zach’s take included

Zach’s take included
Other Structures
Coverage TypesOther Structures coverage (Coverage B on a standard homeowners policy) protects detached structures on the insured's property that are not the primary dwelling — such as detached garages, sheds, fences, gazebos, and guest houses. It is typically set at 10% of the dwelling coverage limit (Coverage A), though this can be adjusted by endorsement. The structure must be separated from the main dwelling by clear space or connected only by a fence, utility line, or similar connection.
Zach’s take included

Common items include jewelry, fine art, musical instruments, firearms, and collectibles.
Zach’s take included
Secondary Home
Policy TermsA 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 TermsA 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

Typically required after serious traffic violations such as DUI, driving without insurance, or accumulating multiple at-fault accidents.
Zach’s take included
Subrogation
ClaimsThe 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 & UnderwritingSurplus 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.
Zach’s take included
U
Umbrella Insurance
Coverage TypesA personal liability insurance policy that provides additional coverage beyond the limits of the insured's existing homeowners, auto, or boat policies. Umbrella policies typically start at $1 million in coverage.
Zach’s take included
