Understanding Course of Construction for Luxury Builds

A course of construction policy, often called builder's risk insurance, is a specialized property policy designed to cover a structure while it's being built. Unlike a standard homeowners policy, it's temporary by design, typically lasting 6 to 12 months with extension options. For luxury builds that frequently stretch past 18 months, this timeline matters. The policy covers the structure itself, materials stored on-site or in transit, and sometimes temporary structures like scaffolding or construction trailers. It's the financial backbone of any custom home project.

What makes luxury construction different from a standard spec home build is the sheer concentration of value. A $4 million estate under construction might have $200,000 worth of reclaimed hardwood flooring sitting in a warehouse waiting for installation, or $80,000 in custom cabinetry arriving from Europe. Your builder's risk policy needs to reflect these values accurately, and that requires more than checking a box on a standard form.

What Builders Risk Covers During the Project

Builder's risk typically covers damage from fire, wind, hail, lightning, vandalism, and theft. Most policies also include coverage for materials in transit and items stored off-site, though sub-limits often apply. If a storm rips off the partially completed roof and water destroys $150,000 in custom millwork below, a properly structured builder's risk policy responds.

Coverage generally begins when materials arrive on-site or construction starts and ends when the home is occupied, sold, or the policy expires, whichever comes first. One critical detail: most builder's risk policies exclude faulty workmanship itself, though they do cover resulting damage. If a subcontractor installs flashing incorrectly and water infiltration ruins interior finishes, the flashing repair isn't covered, but the damaged finishes typically are.

Unique Risks for High-Value Materials and Finishes

Standard builder's risk policies often cap theft coverage at $25,000 to $50,000. That's fine for a production home. For a luxury build with $60,000 in copper roofing panels or $40,000 in smart home wiring waiting to be installed, those limits are dangerously low.

Custom materials also carry replacement timeline risk. If a shipment of hand-painted tiles from Portugal is destroyed, you can't just reorder them and have replacements next week. The lead time might be four to six months, which cascades into construction delays, extended general conditions costs, and potentially breached completion deadlines. This is where the conversation moves beyond basic builder's risk and into endorsements that cover delay-related expenses: a topic we'll get to shortly.

Navigating the Transition to Permanent Homeowners Insurance

The shift from construction coverage to permanent homeowners insurance is one of the most mishandled transitions in luxury home ownership. Too many owners assume their builder or general contractor handles this automatically. They don't. The builder's risk policy expires or terminates, and if you haven't activated a homeowners policy, you're sitting in a multi-million-dollar home with zero coverage.

This transition requires coordination between your insurance advisor, your builder, your lender (if applicable), and often your architect. The goal is a clean handoff with no gap in coverage, not even for a single day. An agency like Avery Insurance Agency, which takes a consultative approach to uncovering vulnerabilities, can map out this timeline months before substantial completion so nothing falls through the cracks.

Timing the Policy Conversion at Substantial Completion

Substantial completion is the trigger point. This is when the home is deemed habitable and ready for occupancy, even if punch list items remain. Your permanent homeowners policy should bind on or before this date. Most builder's risk policies explicitly exclude coverage once the home is occupied, so overlap is better than a gap.

The practical approach is to begin quoting your permanent policy 60 to 90 days before your projected move-in date. For luxury homes, the underwriting process with specialty carriers like PURE, Chubb, or AIG Private Client takes longer than a standard policy. These carriers often want to conduct their own replacement cost appraisal, review construction specifications, and assess site-specific risks. Starting early gives you time to get accurate valuations and avoid being forced into a rushed, poorly structured policy.

Why Standard Policies Often Fall Short for Luxury Assets

A standard HO-3 policy from a mass-market carrier might cap personal property coverage at 50% to 70% of your dwelling limit. For a home insured at $3.5 million, that's $1.75 million to $2.45 million in contents coverage. Sounds generous until you tally up fine art, wine collections, custom furniture, and jewelry. High-net-worth families routinely exceed those limits.

Standard policies also tend to use actual cash value for certain loss categories, meaning depreciation reduces your payout. Specialty carriers offer agreed-value or guaranteed replacement cost that eliminates depreciation from the equation entirely. They also include worldwide coverage for personal belongings, mysterious disappearance protection for jewelry and fine art, and higher liability limits that match the exposure profile of affluent households. Comparing carriers like PURE, Chubb, Cincinnati, and AIG Private Client reveals meaningful differences in how each handles custom construction and high-value personal property.

Comparing Coverage Needs: Construction vs. Occupancy

The risks you face during construction look nothing like the risks you face once you're living in the home. Understanding these differences helps you avoid both over-insuring during the build and under-insuring after move-in.

During construction, theft of materials, weather damage to exposed structures, and contractor liability dominate the risk profile. Once you're in the home, the concerns shift to personal property protection, premises liability (think: a guest slipping on your pool deck), and lifestyle-related exposures like domestic staff or high-value vehicle collections.

Coverage Comparison Chart

This chart makes one thing clear: neither policy alone covers everything. The construction phase needs a general liability policy alongside builder's risk, and the permanent policy needs endorsements and scheduled items to fully protect a luxury lifestyle.

Specialized Endorsements for Custom Estates

Off-the-shelf policies, whether for construction or occupancy, rarely fit a custom estate without modification. Endorsements fill the gaps, and for luxury homes, several are practically mandatory.

The rebuild cost for custom homes is moving further apart from market value, which makes accurate valuation endorsements and guaranteed replacement cost provisions more important than ever. A home that sells for $4 million might cost $5.5 million to rebuild to the same specifications, especially when custom materials and specialized labor are involved. Your policy needs to reflect the rebuild number, not the purchase price.

Soft Costs and Delay in Completion Protection

If a covered loss delays your construction project by three months, the direct damage to the structure is only part of the financial hit. You're also looking at extended loan interest, architect and engineering fees for redesign, additional general conditions costs, permit renewal fees, and potentially temporary housing expenses.

A soft costs endorsement covers these delay-related expenses. For a luxury build carrying a $2.5 million construction loan, three months of additional interest alone could exceed $40,000. Add in extended contractor overhead, and you're easily past $100,000 in costs that a basic builder's risk policy ignores entirely. This endorsement is one of the most valuable and most overlooked protections available during construction.

Equipment Breakdown and Smart Home Integration

Modern luxury homes are technology-dense environments. Whole-home automation systems, geothermal HVAC, solar arrays with battery storage, elevator systems, commercial-grade kitchen equipment: these aren't standard appliances. They're complex mechanical and electrical systems that can fail in expensive ways.

An equipment breakdown endorsement covers sudden and accidental mechanical or electrical failure of these systems. This is distinct from your standard property coverage, which typically requires an external cause like fire or lightning. If your $30,000 geothermal heat pump suffers a compressor failure during its first winter, equipment breakdown coverage responds. Given that housing starts have faced headwinds in 2026 and replacement equipment lead times have stretched, having this coverage means you're not waiting months out of pocket for a critical system repair.

Common Questions About Insuring New Luxury Homes

Do I need both builder's risk and a general liability policy during construction? Yes. Builder's risk covers property damage to the structure and materials. General liability covers bodily injury and property damage claims from third parties. They're separate policies that work together.

Can I just extend my builder's risk policy instead of buying homeowners insurance? No. Builder's risk policies are designed for unoccupied structures under construction. Once you move in, the policy either terminates or won't pay claims. You need a permanent homeowners policy.

What dwelling value should my permanent policy reflect? Your policy should reflect full replacement cost, not market value or purchase price. For custom homes, this often means a detailed appraisal by a firm experienced with luxury construction. Expect replacement costs of $350 to $600+ per square foot depending on finishes and location.

How do I insure a wine cellar, art collection, or jewelry? These items need to be individually scheduled on your policy with agreed-upon values. Standard personal property coverage applies blanket limits and sub-limits that won't adequately protect high-value collections.

Are flood and earthquake covered under my homeowners policy? Almost never. These require separate policies regardless of your carrier. Even inland properties can carry flood risk, and your home insurance outlook for 2026 should include an honest assessment of these exposures.

Should I work with a specialty carrier or a standard insurer? For homes valued above $1.5 million with custom construction, specialty carriers like PURE, Chubb, or AIG Private Client consistently outperform standard market options in claims handling, coverage breadth, and risk management services.

Making the Right Choice for Your Investment

Getting insurance right for a luxury new build isn't about finding the cheapest premium. It's about eliminating the gaps that turn a covered loss into a financial catastrophe. The construction phase demands a properly structured builder's risk policy with adequate limits for high-value materials, soft costs protection, and coordination with your contractor's general liability program. The transition to permanent coverage requires early planning, accurate replacement cost valuations, and a carrier equipped to handle the complexity of a custom estate.
