A lease can make a good commercial deal work - or quietly turn it into an expensive problem. When clients ask about types of leases commercial properties use, they are usually really asking a bigger question: who is paying for what, and how much risk is being transferred between landlord and tenant?

That question matters even more in California, where operating costs, insurance, maintenance obligations, and local market conditions can shift the economics of a space fast. Whether you are a retail tenant in San Gabriel, an investor evaluating a small office building in Arcadia, or a landlord preparing to market vacancy, the lease structure is not a detail. It is the business model behind the occupancy.

The main types of leases commercial deals rely on

Most commercial leases fall into a few core categories: gross lease, modified gross lease, net lease, percentage lease, and ground lease. The names sound straightforward, but the real value is in the fine print. Two leases can carry the same label and still produce very different financial outcomes.

In practical terms, the difference comes down to base rent, additional rent, and responsibility for property expenses. Those expenses usually include property taxes, insurance, common area maintenance, utilities, repairs, and building systems. Before comparing rental rates, you need to know whether the quoted number is all-in or only the starting point.

Gross lease

In a gross lease, the tenant pays a set rent and the landlord covers most or all of the property’s operating expenses. For tenants, this is often the easiest structure to budget because monthly occupancy costs are more predictable. If you are a small business watching cash flow closely, that predictability can be a major advantage.

For landlords, the trade-off is exposure to rising costs. If taxes increase, insurance premiums jump, or maintenance runs above expectations, the landlord absorbs that pressure unless the lease allows expense stops or pass-throughs. That is why a true full-service gross lease is more common in some office settings than in many retail or industrial properties.

Gross leases can look attractive on the surface because the rent quote appears simple. Still, tenants should confirm exactly what is included. Janitorial, utilities, HVAC after-hours use, and repair obligations are common points of confusion.

Modified gross lease

A modified gross lease sits in the middle. The tenant pays base rent, and certain operating expenses are shared or passed through based on negotiated terms. In many cases, the landlord covers some building-wide costs while the tenant pays utilities, interior maintenance, or expense increases over a base year.

This structure is popular because it gives both sides some flexibility. A landlord can protect against inflation in operating expenses without pushing every cost directly onto the tenant. A tenant gets more clarity than under a fully net structure, but may still have some variable monthly charges.

For many small to mid-size commercial users, modified gross is where deals get done. It can be tailored to fit office, medical, or mixed-use space, especially in competitive submarkets where landlords want a more marketable rent structure.

Net lease

Net leases shift some or most property expenses to the tenant. This is where many investors focus because net leases can create cleaner income projections for landlords. But not all net leases are the same.

Single net lease

In a single net lease, the tenant usually pays base rent plus property taxes, while the landlord covers insurance and maintenance. This structure is less common than other versions, but it does appear in some deals. For tenants, it adds one major variable expense without transferring every cost.

Double net lease

In a double net lease, the tenant typically pays base rent plus property taxes and insurance. The landlord may still remain responsible for structural maintenance or certain common area costs. Compared with a gross lease, the rent may appear lower, but the tenant’s total occupancy cost can be less predictable.

Triple net lease

The triple net lease, often written as NNN, is one of the most common structures in retail and single-tenant commercial real estate. The tenant pays base rent plus property taxes, insurance, and maintenance or common area expenses. In many cases, that means the tenant is covering most of the property’s ongoing operating costs.

Landlords like NNN leases because they can reduce management burden and stabilize net income. Investors also value them because they often produce a clearer return profile. Tenants may accept NNN terms in exchange for control over the space, long-term occupancy, or a lower base rental rate.

That said, NNN is not automatically better for either side. A tenant in an older building with deferred maintenance can face major expense exposure if the lease is broad. A landlord using a NNN structure still needs tight lease drafting around roof, structure, parking lot, and capital expenditures. Those details decide whether the lease performs as expected.

Percentage leases and when they make sense

A percentage lease is most common in retail. The tenant pays a base rent and then pays an additional percentage of gross sales once a certain sales threshold is reached. This aligns landlord and tenant interests because the landlord benefits when the tenant performs well.

For a strong retail center with proven foot traffic, this model can help secure tenants while preserving upside. For tenants, it can lower the fixed rent burden during the early stage of business growth. But it also requires careful attention to how sales are defined, what deductions are allowed, and how reporting is handled.

In other words, this lease can be smart for the right retail environment, but it is not something to sign casually. If the reporting language is vague, disputes can follow quickly.

Ground leases for long-term control

A ground lease is different from a standard space lease because the tenant leases the land and typically builds or operates improvements on it. These leases often run for long terms, sometimes decades, and are common in major retail, development, and institutional situations.

For landowners, a ground lease can create income while preserving long-term ownership of a valuable site. For tenants or developers, it offers control of a location without the upfront capital required to buy the land. The economics can be compelling in high-value California corridors where land is expensive and strategic sites are limited.

The downside is complexity. Ground leases usually involve financing considerations, use restrictions, redevelopment rights, assignment provisions, and end-of-term questions about ownership of improvements. They require a more strategic review than a typical storefront lease.

Which commercial lease is best?

There is no universal winner among the types of leases commercial landlords and tenants use. The best structure depends on the property, the business, and the negotiating leverage on each side.

If you are a tenant prioritizing cost certainty, a gross or modified gross lease may be more attractive than a NNN lease. If you are an investor seeking passive income and limited expense exposure, a well-negotiated triple net lease may fit your goals better. If you are leasing retail space in a high-traffic center, a percentage lease may create a more workable launch point than a high fixed rent.

The California factor matters too. In higher-cost markets, small wording differences around operating expenses, maintenance caps, expense stops, or capital repairs can change the real economics of a deal. A lower quoted rent is not always the better deal if the pass-through language is broad.

What to review before signing any lease

Before signing, both landlords and tenants should look beyond the lease label. Start with the rent structure, but do not stop there. Review expense pass-throughs, repair responsibilities, annual increases, renewal options, use clauses, exclusivity terms, assignment and subleasing rights, and default remedies.

For tenants, one of the biggest mistakes is underwriting only the base rent. For landlords, a common mistake is assuming a standard form lease fully protects the asset. It often does not, especially when property conditions, tenant operations, or mixed-use elements create gray areas.

This is where experienced representation matters. A strong lease strategy is not just about getting signatures. It is about matching lease structure to investment goals, business operations, and market reality. In active Southern California markets, speed matters, but clarity matters more.

The right commercial lease should support growth, protect value, and leave fewer surprises after move-in. If a lease structure looks simple, that is exactly when it deserves a closer look.
