Understanding the Landlord Tenant Relationship

A lease is both a conveyance of an interest in land and a contract. It gives the tenant the right to exclusive possession of the property for a period of time in exchange for rent. Paralegals in real estate practice draft, review, and track leases, and certification exams commonly ask how commercial and residential leases differ. Although they share the same basic framework, the law treats them very differently because of the different bargaining positions of the parties.

Types of Leasehold Estates

Both commercial and residential leases can fall into one of four traditional categories:

Term of years: a lease for a fixed period that ends automatically on a set date, with no notice required. Under the statute of frauds, leases longer than one year generally must be in writing.
Periodic tenancy: a lease that renews automatically for successive periods, such as month to month, until one party gives proper notice.
Tenancy at will: a tenancy with no fixed duration that either party can end at any time, subject to statutory notice requirements.
Tenancy at sufferance: occurs when a tenant remains in possession after the lease expires without the landlord's consent, also called a holdover.

Key Differences Between Commercial and Residential Leases

How Does the Warranty of Habitability Apply?

In residential leases, nearly every state recognizes an implied warranty of habitability. The landlord promises that the premises are fit for human living, with essential services such as heat, water, and safe structure, and that the premises comply with housing codes. This warranty cannot usually be waived. If the landlord fails to make repairs, a tenant may have remedies such as repair and deduct, rent withholding or payment into escrow, termination of the lease, or suing for damages. In commercial leases, there is generally no implied warranty of habitability. Commercial tenants are presumed to be sophisticated businesses able to negotiate their own repair obligations, so the responsibilities are set out in the lease.

Who Has More Bargaining Power?

Residential leases tend to be standardized forms with limited negotiation, and consumer protection statutes apply. Commercial leases are heavily negotiated and may run to dozens of pages. The courts give commercial parties more freedom of contract and will generally enforce their terms as written.

How Long Do the Terms Run?

Residential leases are most often for one year or month to month. Commercial leases frequently run for five, ten, or more years and often include renewal options, expansion rights, and rent escalation clauses.

What Is Included in the Rent?

Residential rent is often a flat monthly sum. Commercial rent can be structured in several ways:

Gross lease: the tenant pays a fixed rent and the landlord pays operating costs.
Net lease: the tenant pays base rent plus some expenses. A single net lease includes property taxes, a double net lease adds insurance, and a triple net lease (NNN) adds maintenance and repairs.
Percentage lease: common in retail, the tenant pays base rent plus a percentage of gross sales.
Modified gross lease: costs are split in a negotiated way.

Commercial leases also commonly require a charge for common area maintenance, abbreviated CAM.

Security Deposits

Residential security deposits are usually capped by statute, must be held or accounted for in prescribed ways, and must be returned within a set number of days after the tenant moves out, with an itemized list of deductions. Landlords who wrongfully withhold deposits may face statutory penalties. Commercial security deposits are generally governed by the lease itself, with far fewer statutory restrictions, and may be much larger or take the form of a letter of credit or personal guaranty.

Assignment and Subletting

An assignment transfers the tenant's entire remaining interest to a third party, while a sublease transfers less than the full term and leaves the original tenant with a reversion. In an assignment, the assignee is in privity of estate with the landlord, and the original tenant stays liable on the lease unless released. In a sublease, the subtenant has no direct relationship with the landlord. Unless the lease says otherwise, tenants may freely assign or sublet. Most leases include a clause requiring landlord consent, and in commercial leases, courts generally enforce these clauses, while some states require the landlord to act reasonably in withholding consent.

Use Restrictions and Other Commercial Provisions

Commercial leases often include provisions that residential leases rarely have, such as exclusive use clauses, which protect a tenant from competitors in the same building, radius restrictions, and permitted use clauses. Other features include subordination, nondisturbance, and attornment agreements (SNDAs) that address what happens if the landlord's lender forecloses, estoppel certificates confirming lease terms, tenant improvement allowances, and personal guaranties from business owners.

Duty to Repair and Maintenance

In residential settings the landlord is generally responsible for structural elements and common areas, and the warranty of habitability controls. In commercial leases, the allocation is whatever the lease says. Under a triple net lease, the tenant may be responsible for nearly everything, including the roof and structure.

Eviction Procedures and Remedies

How Do Evictions Differ?

Landlords may not use self help remedies, such as changing locks or shutting off utilities, to evict a residential tenant in most states. They must go through a judicial process, often called unlawful detainer or summary possession, after giving proper written notice such as a pay or quit notice. Retaliatory eviction against a tenant who complains about code violations, and discriminatory eviction in violation of fair housing laws, are prohibited. Commercial landlords may have greater remedies and, in some states, limited self help rights, although many states still require court process. Commercial leases usually spell out default events and remedies in detail.

What About Landlord Duties on Re-Letting?

If a tenant abandons the property, the majority of jurisdictions now require the landlord to make reasonable efforts to mitigate damages by re-letting the premises. Some states have historically excused commercial landlords from this duty, so check local law.

Constructive Eviction

Constructive eviction occurs when the landlord substantially interferes with the tenant's use and enjoyment of the premises, forcing the tenant to leave. To claim it, the tenant must give notice, allow time to cure, and actually vacate within a reasonable time. It applies in both commercial and residential settings.

Fair Housing and Discrimination

The federal Fair Housing Act prohibits discrimination in residential housing based on race, color, religion, sex, familial status, national origin, and disability. The Act does not apply in the same way to commercial leases, though other laws, such as the Americans with Disabilities Act, impose accessibility duties on commercial spaces that serve the public.

What Paralegals Do

Paralegals prepare lease drafts from attorney instructions, build lease abstracts that summarize key dates and terms, track renewal and termination notice deadlines, collect estoppel certificates, and assist with eviction filings. Careful calendaring of option exercise windows can save a client from losing valuable rights.

Key Takeaways

Residential leases are shaped by consumer protection, including the implied warranty of habitability, deposit rules, and limits on eviction. Commercial leases are governed mostly by the terms the parties negotiate, with varied rent structures such as triple net, longer terms, and fewer statutory protections. Knowing these differences will help you on the exam and on the job.
