GL class codes 61212 and 61217 are the standard general liability classifications for a lessors risk only building, one leased to tenants for bank, office, mercantile or manufacturing use. Carrier materials split them on who maintains the building: 61212 when the tenants do, 61217 when the owner does. Not-for-profit owners have their own versions.
What the two codes say
The descriptions carriers print for these codes are long, and the length is the point. Both read “Buildings or Premises, Bank or Office, Mercantile or Manufacturing (Lessor’s Risk Only), Other Than Not-For-Profit,” and the second adds the words “Maintained by the Insured.” That one added phrase is the entire difference between 61212 and 61217.
The lessor’s risk only wording is the part that ties these codes to this site’s subject. It marks a building occupied by tenants rather than by its owner, which is the same underwriting classification explained in what lessor’s risk insurance is. The codes do not describe your tenants’ businesses. They describe the owner’s position: somebody else operates inside the building.
We checked this against three carrier and underwriter documents, not against the classification manual itself, which is a proprietary publication we did not retrieve. A small-business product sheet from one carrier labels 61217 as lessor’s risk maintained by the insured and 61212 as lessor’s risk maintained by the tenants. Two pages from a lessor’s risk underwriter list the same descriptions and describe 61212 as an exposure where the owner is not responsible for maintenance and upkeep, and 61217 as one where the owner is. The same product sheet lists a rating basis beside each code, and for both of these the basis is area, which is a measure of the size of the premises. All three agree with each other. Treat them as what carriers say about these codes, and confirm the exact wording with the carrier writing your policy.
Why the split is about maintenance
Maintenance is a proxy for control. A building the owner keeps up is a building where the owner decides about the roof, the parking surface, the stairs and the lighting, and where a claim about a condition of the property points at the owner’s own conduct. A building the tenants keep up moves much of that day-to-day control to them.
- Tenants maintain the building
- Upkeep of the premises sits with the tenants under the lease. The owner leases the space and does not run it. Carrier materials file this under the first code of the standard pair.
- The owner maintains the building
- The owner keeps up the structure and the shared areas, and decides about the roof, the lot and the walkways. Carrier materials file this under the second code of the standard pair.
That is why the question is answered by the lease and by what actually happens, in that order. A lease that makes the tenants responsible for the premises, the common areas and repairs is the kind of arrangement described in NNN leases: who insures what. A lease that leaves the structure and the shared areas with the owner points the other way. One building can mix the two patterns, a net lease for one tenant and owner-maintained shared space for the rest, and that is the situation where the classification needs a direct conversation rather than an assumption.
Real-World Scenario: An owner buys a small commercial building let to several tenants. The lease template says the tenants maintain their own suites, and the quote comes back under the tenant-maintained class. In practice the owner clears the shared walkway, hires the parking lot contractor and fixes the roof when it leaks, because none of the tenants will. A visitor falls on the walkway. Nothing about the tenants was misdescribed, but the classification described a building the owner does not run. The owner never lied and was never asked, and a carrier would reasonably want to know who was maintaining the walkway.
The not-for-profit pair
The same materials list two further codes, 61216 and 61218. They are the not-for-profit versions of 61212 and 61217, split the same way: 61216 for a not-for-profit owner whose tenants maintain the building, and 61218 for a not-for-profit owner who maintains it. The underwriter we retrieved calls both uncommon office or retail exposures.
For most commercial owners that pair is simply background. If the ownership entity is not a not-for-profit, the pair that applies is 61212 and 61217, and the entity question is the same one that decides who belongs on the policy as a named insured, covered in named insured versus additional insured.
SIC and NAICS are not GL class codes
Searches for a lessors risk SIC code are common, and the honest answer is that no SIC code means lessors risk, because lessors risk is an insurance classification and SIC and NAICS classify industries. The closest industry entries are real, though, and both are published by government agencies.
The Standard Industrial Classification manual that OSHA publishes carries 6512, operators of nonresidential buildings. Its current successor system, NAICS, carries 531120, lessors of nonresidential buildings, and the Census Bureau’s NAICS definition includes owner-lessors of nonresidential buildings. The underwriter tables we retrieved show 531120 beside each of the four class codes, as a cross-reference between systems. That is the whole relationship. An industry code tells you what kind of business the owner is. The GL class code is the insurer’s own classification of the premises, and the two are not interchangeable on an application.
Choosing the code is the carrier’s job, informing it is yours
A classification is assigned by the carrier from what you tell it. So the useful work on the owner’s side is to give the carrier accurate facts and to read what came back.
Start with the lease: who is responsible for the structure, the roof, the parking areas, the shared walkways and the exterior. Then compare it with the way the property is actually run, because a lease can say one thing while the owner’s crew does another. Ask the carrier or your agent to state the classification and its rating basis in writing. And look for it on the paperwork: the way to read the entity, the limits and the other particulars of a policy is covered in the declarations page and the two pages nobody reads.
Where the answer is not clean, say so. A building with a net lease for one tenant and an owner-run shared area is not a failure of the classification system. It is a fact the carrier needs, and it is better to surface at the quote than at a claim.
What a class code does not tell you
A class code is not a coverage grant. It tells you how the insurer has classified the premises for general liability rating, and it does not tell you what the policy covers. The sections of this site that do that work are general liability for the liability side and commercial property for the building, with business income and loss of rents covering the rent.
Two other things sit outside the code. Your tenants’ own operations and their own coverage are a different question, and what you can and cannot rely on from their policy is treated in what a landlord needs on the tenant’s policy. And a building that stops being occupied changes the picture altogether, because the vacancy provisions that start running then are their own subject in the vacancy clause and when it starts running.
The three building types this brand writes, mixed-use, retail and office, each bring their own considerations to the underwriting conversation. The classification is where that conversation starts, not where it ends.
What to ask before you bind
Four questions cover most of it. Which class code and description has the carrier assigned to each building, and what rating basis sits beside it. What maintenance assumption sits behind that code, in the carrier’s words. Whether the lease and the actual practice match that assumption. And what happens to the classification if a tenant leaves and the owner takes over the upkeep of space that was maintained by the tenant.
For the wider picture, the Insurance Information Institute publishes commercial coverage background, the Small Business Administration covers the buyer’s side, and your state’s department of insurance is listed in the NAIC directory. If you want the classification on your own building read against your lease, tell us what you own and who maintains it. That is the first question we ask.
