Glossary of Common Rental Terms Every Tenant Should Know

Why This Glossary Matters

Leases and rental agreements are full of legal terms that can be confusing. Understanding these terms helps you negotiate better, protect your rights, and avoid costly mistakes. This glossary covers the most common rental terms in plain English.

A–B

Abatement

A reduction in rent, often granted when a unit has a habitability issue that makes it partially unusable. For example, if your AC breaks in summer and the landlord can't fix it for a week, you might receive a rent abatement for that period.

Addendum

A document added to a lease that modifies or adds terms. Common addenda include pet addenda, parking addenda, and lead-paint disclosure addenda. The addendum is part of the lease.

Application Fee

A non-refundable fee charged to process your rental application, covering credit checks, background checks, and administrative costs. In Texas, there is no cap on application fees.

Assignee

A person who takes over your lease entirely, assuming all your rights and responsibilities. If you assign your lease, you're typically no longer responsible — but check your lease terms.

Breach of Lease

A violation of the lease terms by either the landlord or the tenant. Examples include the tenant not paying rent or the landlord not making required repairs.

C–D

Co-Signer (Guarantor)

A person who agrees to be financially responsible for the lease if the primary tenant fails to pay. Often used when a tenant doesn't meet income or credit requirements.

Concession

A discount or incentive offered by a landlord, such as a free month of rent or reduced security deposit. Often offered when the rental market is slow.

Constructive Eviction

A legal doctrine where the landlord's actions (or failure to act) make the unit uninhabitable, effectively forcing the tenant to move. The tenant may be able to break the lease without penalty.

Cosigner vs. Guarantor

These terms are often used interchangeably, but technically a cosigner is equally responsible on the lease, while a guarantor is only responsible if the primary tenant defaults.

Default

Failure to fulfill a lease obligation, most commonly failing to pay rent on time.

Deposit (Security Deposit)

Money held by the landlord to cover potential damages, unpaid rent, or other lease violations. Must be returned within 30 days of move-out in Texas, minus any lawful deductions.

E–F

Eviction

The legal process of removing a tenant from a rental property. In Texas, evictions must go through the court system — a landlord cannot simply change the locks or remove a tenant's belongings (this is illegal and called a "self-help eviction").

Fair Housing Act

Federal law that prohibits discrimination in housing based on race, color, national origin, religion, sex, familial status, and disability.

Fixed-Term Lease

A lease for a specific period (e.g., 12 months) with a set start and end date. The rent amount and terms cannot change during the term.

Force Majeure

A clause that excuses both parties from fulfilling lease obligations due to extraordinary events (natural disasters, war, etc.). Rarely applies to residential leases.

G–H

Grace Period

A period after the rent due date during which the tenant can pay without penalty. Texas law does not require a grace period, but many leases include one (1-5 days).

Guest

A person who stays in the unit temporarily. Most leases define how long a guest can stay (often 7-14 days) before they're considered an unauthorized occupant.

Habitability

The legal standard that a rental must be safe, sanitary, and fit for human habitation. Texas's implied warranty of habitability requires landlords to maintain these conditions.

I–L

Implied Warranty of Habitability

A legal doctrine (not written in your lease but implied by law) requiring landlords to provide and maintain a livable rental unit.

Joint and Several Liability

A legal principle where multiple tenants on a lease are each individually responsible for the full rent and lease obligations. If one tenant doesn't pay, the others are responsible for the full amount.

Lease

A binding contract between a landlord and tenant that outlines the terms of the rental, including rent, duration, and rules.

Lease Term

The duration of the lease, typically 6, 12, or 24 months. Shorter terms offer flexibility but may have higher rent.

M–N

Month-to-Month Lease

A rental agreement that renews each month and can be terminated by either party with notice (usually 30 days in Texas). Offers flexibility but less stability than a fixed-term lease.

Notice to Vacate

A written notice that a tenant or landlord is ending the tenancy. Texas law requires tenants to give notice per the lease terms, often 30-60 days.

Normal Wear and Tear

The natural deterioration of a rental property from everyday use. Landlords cannot deduct from the deposit for normal wear and tear — only for damage beyond it.

O–R

Occupant vs. Tenant

A tenant is a party to the lease; an occupant is someone who lives in the unit but isn't a lease signatory (e.g., a child or family member).

Pet Deposit

A separate deposit for pet-related damage, in addition to the standard security deposit. Some landlords charge a pet deposit, pet rent, or both.

Quiet Enjoyment

Your right to use and enjoy the rental property without unreasonable interference from the landlord. This is implied in every lease.

Repair and Deduct

A legal remedy allowing tenants to pay for necessary repairs and deduct the cost from rent, if the landlord fails to repair after proper notice (Texas Property Code § 92.056).

Renters Insurance

Insurance that covers a tenant's personal belongings and liability. Many leases require renters insurance. It's relatively inexpensive ($10-$20/month) and highly recommended.

S–T

Sublease

When a tenant rents the unit to another person (a subtenant) while remaining on the lease. The original tenant is still responsible to the landlord. Most leases require landlord approval.

Security Deposit

See Deposit.

Squatter's Rights (Adverse Possession)

A legal doctrine where someone who occupies a property without permission for an extended period may gain legal rights. This is extremely rare in rental contexts.

Subtenant

See Sublease.

Tenant at Will

A tenant who occupies the property with the landlord's permission but without a formal lease. Essentially a month-to-month tenancy.

U–W

Unlawful Detainer

A lawsuit filed by a landlord to evict a tenant who is unlawfully remaining in the property after the lease ends or is terminated.

Wear and Tear

See Normal Wear and Tear.

Writ of Possession

A court order allowing the landlord to take possession of the property, typically executed by a constable or sheriff after an eviction judgment.
