The property section is the part of a lessors risk policy owners think they understand. It insures the building. What it actually pays, though, is decided by three choices buried in the declarations — the valuation basis, the coinsurance condition, and whether ordinance or law was bought — and none of those is obvious from the premium.

Those three choices are the difference between a settlement that rebuilds your building and one that funds part of it. They are worth understanding before a loss, because afterwards they are simply facts about your policy.

What is insured, and what belongs to your tenant

The building is the obvious part: structure, roof, permanently installed systems, fixtures, and the equipment that serves the property itself. Less obvious is your business personal property — the maintenance equipment, common-area furnishings, groundskeeping gear and tooling a landlord accumulates. It is not much next to the building, and it is routinely left off the schedule entirely.

What is not yours is the tenant’s stock, their equipment, and the improvements they paid for. Those belong on their policy. The line between the two is drawn by the lease rather than by common sense, and it moves: many leases assign improvements to the owner on installation, others on lease expiry, and some never address it at all. Once an improvement belongs to you, it belongs in your building value — and until then, insuring it means paying premium on somebody else’s property.

This is the most common quoting error we see on a first submission: a building value carried forward from a purchase appraisal, with no adjustment for a decade of tenant buildouts that the leases quietly transferred to the owner.

Valuation: replacement cost versus actual cash value

Replacement cost pays what it takes to rebuild with materials of like kind and quality at current prices. Actual cash value pays that figure reduced for depreciation — the age and condition of what was destroyed comes off the settlement before it reaches you.

On a newer building the two are close. On an older one they are not, and the difference lands entirely on the owner. A roof most of the way through its service life settles for a fraction of what a new roof costs under actual cash value; under replacement cost it settles for the new roof. That single line in the declarations can decide whether a serious loss is a repair or a rebuild you have to fund.

Neither basis is universally right. Actual cash value carries a lower premium and can be the sensible choice on a property being held for redevelopment. What is never right is not knowing which one you bought.

Coinsurance, and the value that quietly went stale

Coinsurance asks you to insure a stated share of the building’s value. Carry less than that share and every claim payment is reduced in proportion — the penalty applies to a broken window as surely as to a total loss, which surprises owners who assume it only matters at the extremes.

The failure is almost never a bad valuation. It is a good valuation that stopped being current: a figure set at purchase, carried forward through renewals nobody questioned, while construction costs and code requirements moved underneath it. The policy does not notice and the premium does not complain.

There are structures that change how this works, including agreed-value arrangements that suspend the condition in exchange for documented values at inception. Whether one is available for your building is a quoting question, and a cheap one to ask.

Ordinance or law: three coverages, not one

This is where an older building costs more to fix than to insure, and it is the gap most owners find out about at the permit desk.

The basic property form pays to repair what was damaged. It does not pay for what the building code then requires you to do to the rest of the structure. Ordinance or law answers that in three distinct pieces, and they are separate grants with separate limits:

• Undamaged portion. When code requires demolition of parts of the building the loss did not touch, this covers their value.
• Demolition cost. The cost of tearing that undamaged portion down and removing the debris — a construction line item the property loss did not create.
• Increased cost of construction. The extra cost of rebuilding to the current code rather than the one the building was built to.

The exposure grows with the age of the structure, because the distance between how a building was built and how it must now be rebuilt widens with every code cycle. A building that predates current requirements for accessibility, fire separation, energy performance or seismic detailing is usually legal to keep and expensive to rebuild. Where a jurisdiction requires a substantially damaged structure to be brought fully to current code, the increased cost can rival the direct damage.

It matters for the income side too. A code-driven rebuild takes longer than a like-for- like repair, which stretches the period of restoration — and the loss of rents limit has to be long enough to cover the version of the rebuild the code will actually require.

What the form does not respond to

The property form answers sudden and accidental events. It does not answer time. Wear and tear, gradual deterioration, settling, rot and deferred maintenance are excluded as causes, and a claim that traces to any of them is a repair bill rather than a loss.

Flood and earthquake are excluded and separately placed — both are their own policies with their own terms, and neither is a rider you can add on the day the forecast turns. Equipment breakdown is usually its own coverage as well, which matters more on an office building with substantial mechanical systems than on a single-story retail strip.

And a vacant building is treated differently once it passes the threshold the policy states. That condition sits on the property coverage and pulls the income coverage down with it — the mechanics are on the loss of rents page.

The extensions that decide what a claim actually pays

Beyond the building limit, a handful of extensions do disproportionate work on a landlord’s claim, and they are the ones most often left at whatever the form gave them.

Debris removal is usually a sub-limit rather than a full one, and on a substantial loss the cost of clearing a site is a construction expense in its own right. Preservation of property covers the steps you take to protect what survived — boarding, drying, temporary security — in the window before the adjuster arrives, which is exactly when an owner is deciding whether to spend money. Pollutant cleanup tends to carry a modest annual aggregate that bears no relationship to what a real remediation costs.

Signs, fences, paving and exterior lighting are frequently treated as outdoor property with their own sub-limit rather than as part of the building — which surprises owners of retail properties, where the pylon sign and the parking field are a meaningful share of the insured value.

How this changes by property type

A mixed-use building with a residential floor is underwritten against fire and occupancy-separation requirements that a single-occupancy commercial building never meets. Retail exposure concentrates in the common areas and the parking field. An office property carries most of its value in systems — elevators, chillers, controls — where the property form and equipment breakdown meet. Same coverage line, three different conversations.

Why Lessors Risk Guard Insurance

We ask for the leases before we quote the building, because the leases decide what is yours to insure. We ask when the value was last set, because that is where the coinsurance problem lives. And we quote ordinance or law explicitly rather than leaving it as a checkbox, because on an older building it is not a refinement — it is most of the gap.

Nothing here binds coverage or interprets your policy. Your form, your endorsements and your leases govern; a licensed agent confirms coverage directly.
