All Risk Insurance Explained: From Builders Risk to Preferred Coverage

All risk insurance is a type of property coverage that protects against any loss or damage not explicitly excluded in the policy, rather than covering only named perils. This open-perils structure makes it broader and generally more valuable than basic named-peril policies for most homeowners and property investors. Understanding builders risk insurance cost is one piece of the puzzle if you’re building or renovating, while preferred risk insurance describes discounted coverage offered to property owners with low claims history or low-hazard locations. Assigned risk insurance is on the opposite end of the spectrum, applying to property owners who can’t get coverage in the standard market. Whether you need standard all risks insurance for a residential property or specialized construction coverage, knowing how each category works helps you find the right policy at the right price.

The terminology varies by insurer and state, but the core concept stays consistent: open-perils policies cover more situations with fewer documentation requirements for the insured to prove a covered loss.

What All Risk Property Coverage Actually Covers

An all-risks homeowner policy covers losses from fire, theft, water damage, wind, and virtually any other cause that isn’t explicitly listed as an exclusion. Common exclusions include floods, earthquakes, and normal wear and tear. This is a broader structure than a standard HO-1 or HO-2 named-peril policy, which only pays for damage from specific listed events. Understanding open-perils property insurance means recognizing that the burden of proof shifts: the insurer must prove that a loss falls under an exclusion rather than the homeowner proving it falls under a covered peril.

Reviewing the exclusions list carefully before buying any all-perils property policy is the most important step. Two policies can both be marketed as all-risk or open-perils coverage and still have very different exclusion lists. One might exclude mold remediation; another might cover it up to a sub-limit. These differences significantly affect the real value of the coverage.

Builders Risk Insurance Cost: What to Expect

Builders risk coverage protects a structure during construction or renovation. The cost of this specialized property insurance typically runs 1–5% of the total construction value annually. A $300,000 construction project would carry a policy premium of roughly $3,000–$15,000 for the build period, though the actual rate depends on project type, location, and coverage scope. Builders risk premiums reflect risk factors like construction timeline, materials used, and whether the site has full-time security.

Construction risk insurance cost goes up when the project includes higher-risk materials like wood framing (more fire susceptibility) versus steel or concrete. Projects in coastal or flood-prone zones also carry surcharges that raise the premium. Many lenders require this coverage before releasing construction loan funds, so factoring the cost into your project budget from the start prevents a last-minute scramble.

Preferred and Assigned Risk: Two Ends of the Market

Preferred risk coverage is offered by standard market insurers to clients who present the lowest risk profile. Properties with good construction, favorable locations, no prior claims, and strong maintenance records qualify for preferred pricing tiers. Getting into the preferred tier can mean paying 15–30% less than the standard market rate for comparable coverage. Maintaining a clean claims history over five or more years is the most reliable path to preferred-risk status.

Assigned risk insurance operates differently. When a property owner cannot get coverage through the voluntary market because of repeated claims, high-risk location, or other factors, most states have an assigned risk pool or FAIR plan that requires insurers to cover these properties on a shared basis. FAIR plan policies are more expensive, offer less coverage, and should be treated as a last resort while you work on addressing the factors that made you uninsurable in the standard market.

Choosing the Right Policy Type for Your Situation

For most residential owners, a standard HO-3 or HO-5 all-risks policy is the appropriate baseline. HO-5 policies apply open-perils coverage to both the dwelling and personal property, while HO-3 applies named-perils coverage to contents only. The premium difference between them is usually small relative to the additional protection for personal belongings that an HO-5 provides.

For commercial property, open-perils commercial property forms offer similar broad coverage adapted for business use, equipment, and inventory. If you’re renovating a building you own, a builders risk policy runs alongside your regular property policy to cover the structure during the construction phase, when standard homeowner policies typically exclude coverage for the work being done.

Next Steps

Pull your current policy declarations page and check whether your coverage is open-perils or named-perils. If it’s named-perils, request a quote comparison for an all-risks form to see what the premium difference looks like. If you’re starting a construction project, get builders risk coverage quotes before breaking ground, not after, and confirm whether your existing property policy continues to cover the undamaged portions of a structure during a renovation.
