The different types of leases fall into four groups: who the property is for (residential or commercial), how operating costs are divided between landlord and tenant (gross, modified gross, single net, double net, triple net, and percentage), how long the agreement runs (fixed-term or month-to-month), and specialized structures that layer in other rights (subleases, assignments, lease-options, lease-purchases, and ground leases). Which type you sign matters because the monthly cost, the length of your commitment, and your exposure to expenses like taxes, insurance, and repairs can look completely different for the same square footage.
Residential and Commercial Leases
The first split is use. Residential leases cover houses, apartments, and condominiums, and they sit inside a thick layer of state law covering security deposits, habitability, eviction procedure, and required disclosures. Most states won’t let a tenant sign away those statutory protections, so the written lease operates within fixed guardrails no matter what it says.
Commercial leases cover offices, retail storefronts, warehouses, and industrial space. The law assumes both sides can negotiate for themselves, so the guardrails are thinner. Rent structure, maintenance duties, length, and renewals are all open. That flexibility lets a commercial tenant negotiate favorable terms, and it also lets them sign up for expenses a residential tenant would never carry.
Gross Leases
Under a gross lease, the tenant pays one flat rent and the landlord covers property taxes, building insurance, maintenance, and sometimes utilities. The monthly number is predictable. The landlord builds operating costs into a higher base rent, so the tenant pays for them indirectly rather than line by line.
A modified gross lease splits the categories. The two sides negotiate which expenses each one covers. One common arrangement has the landlord paying taxes and insurance while the tenant handles utilities and janitorial costs. Every modified gross deal is its own creature, which makes comparison harder and leaves more room to shape terms that fit the situation.
Net Leases
Net leases push operating costs onto the tenant in layers. Each “net” adds another expense category on top of base rent.
- Single net lease (N): the tenant pays base rent plus property taxes. The landlord still handles insurance and maintenance.
- Double net lease (NN): the tenant pays base rent plus property taxes and building insurance. The landlord keeps responsibility for structural maintenance.
- Triple net lease (NNN): the tenant pays base rent plus property taxes, insurance, and all maintenance and repair costs. The landlord’s role shrinks to collecting rent and holding title.
Triple net leases are common for freestanding retail buildings and single-tenant commercial properties. The base rent is lower than a gross lease because the tenant absorbs every operating cost, which also means the tenant is on the hook if the roof needs replacing or property taxes spike. Before signing a triple net, look hard at the condition of the building and the direction of local taxes.
Percentage Leases
Percentage leases show up most often in retail, especially in shopping malls and high-traffic centers. The tenant pays base rent plus a percentage of gross sales once revenue clears a threshold called the breakpoint. Below the breakpoint, nothing is owed beyond base rent.
A natural breakpoint equals the annual base rent divided by the agreed percentage. Base rent of $60,000 a year at 6% produces a natural breakpoint of $1,000,000 in gross sales; the percentage then applies to every dollar above that. An artificial breakpoint is a flat number the two sides negotiate directly, set higher or lower than the natural calculation. A higher artificial breakpoint favors the tenant; a lower one favors the landlord.
The structure ties the landlord’s income to the tenant’s success, which is why landlords in percentage lease deals pay close attention to tenant mix and foot traffic.
Fixed-Term and Month-to-Month Leases
A fixed-term lease locks in start and end dates, typically one year for residential and three to ten years for commercial. Rent and terms stay stable through the term, and neither side can walk away or change the deal without consequences before it expires. When the term ends, the parties either sign a new lease, let the tenancy roll into a month-to-month, or part ways. If the lease is silent and the tenant keeps paying, most states treat the arrangement as a month-to-month that carries forward the expired lease’s terms.
A month-to-month lease renews automatically each rental period until one side gives written notice to end it. The required notice usually runs 30 to 60 days, depending on the state. The flexibility is the point: the tenant can relocate without waiting out a long term, and the landlord can adjust rent or reclaim the unit on short notice. The flip side is that neither party has any guarantee of stability from one month to the next.
Subleases and Assignments
When a tenant needs to leave before the lease ends, two mechanisms can hand occupancy to someone else, and they look similar but create very different legal relationships.
In a sublease, the original tenant rents all or part of the property to a subtenant. The original tenant stays on the lease and remains responsible for rent, condition, and every other obligation. The subtenant pays the original tenant, not the landlord, and the landlord has no direct contract with the subtenant. If the subtenant stops paying, the original tenant still owes.
An assignment is a full transfer. The original tenant hands over all remaining rights and duties to a new tenant, who then deals directly with the landlord. Once the landlord consents and the assignment is complete, the original tenant is typically released from further obligation. Most leases require written landlord approval for either move, and some prohibit them outright. State law sometimes overrides those restrictions, particularly in residential settings where a blanket ban on subleasing may not stand up.
Lease-Option and Lease-Purchase Agreements
Both of these blend renting with a path toward buying, but one critical difference separates them.
A lease-option gives the tenant the right, not the obligation, to buy the property at a predetermined price when the lease ends. The tenant pays an upfront option fee and may have a slice of each month’s rent credited toward the purchase price. If the tenant walks, they usually forfeit the option fee and any rent credits, but they aren’t forced to buy. During the option period, the landlord cannot sell to anyone else.
A lease-purchase obligates both sides to close the sale. The tenant commits to buying and the landlord commits to selling at the agreed price. Walking away carries real legal consequences on either side, similar to breaching any other purchase contract. The distinction matters: if the property’s value drops or finances change, a lease-option lets the tenant walk with limited losses, while a lease-purchase can leave the walker facing a lawsuit for specific performance or damages.
Both structures usually involve an option fee, rent credits, and a locked-in purchase price. Which credits are refundable, and under what conditions, deserves close reading, because forfeiting several years of accumulated credits on a deal that falls through can be a serious loss.
Ground Leases
A ground lease separates ownership of land from ownership of what sits on it. The landowner leases bare land to a tenant, who then builds on it at their own expense. Terms usually run 50 to 99 years so the tenant has time to recoup construction and generate returns.
The catch arrives at expiration. In most ground leases, any buildings and improvements the tenant put up revert to the landowner. Some agreements instead require the tenant to demolish improvements and return the land to its original condition. Either way, the tenant loses the physical investment at the end of the term unless a renewal or extension is negotiated.
Ground leases are common in dense urban areas where land is extremely valuable and owners want to keep it long term while generating income. Tenants accept the structure because it avoids the huge upfront cost of buying the land, freeing capital for construction and operations.
What If You Need to Leave Early
Lease type also shapes what happens if a tenant has to leave before the term ends. Many residential leases include an early termination clause with a flat penalty, commonly one to two months’ rent, in exchange for a clean break. Without that clause, the tenant may be liable for rent through the end of the term, though roughly half of states require landlords to make reasonable efforts to re-rent the unit, which shrinks the exposure to the gap period plus reletting costs.
Commercial leases can be harsher. Some include acceleration clauses that make the entire remaining rent balance due immediately on default, and courts have upheld those between commercial parties, particularly where the lease also waives the landlord’s duty to find a replacement tenant. Residential tenants almost never face acceleration clauses, and most states would not enforce one in a residential context even if a landlord included it.
Before vacating, check the lease for termination provisions and the state’s mitigation rules, and talk to the landlord. A negotiated exit almost always costs less than an adversarial one.
