A landlord is a person or business that owns property and rents it to someone else in exchange for payment. That ownership-plus-rent arrangement is what the law looks at, not the landlord’s size or structure. A landlord can be one person renting out a spare house, a couple with a duplex, an LLC holding investment property, or a corporation managing hundreds of units. Whatever the form, the role carries a defined set of legal duties toward the tenant and a defined set of rights over the property.
How the Relationship Begins
The landlord-tenant relationship forms the moment one party owns property and another pays to occupy it. Most of the time, a written lease spells out the rent, the payment schedule, the length of the tenancy, and each side’s obligations. A written lease is not strictly required in most jurisdictions. If someone occupies another person’s property and pays for the privilege, courts will usually recognize the relationship anyway. Operating without a written lease, though, tends to produce disputes neither side can prove.
What a Landlord Must Do
Keep the Property Livable
The single biggest obligation a residential landlord carries is keeping the property fit to live in. Nearly every state recognizes some version of the implied warranty of habitability. The property doesn’t have to be luxurious, but the fundamentals have to work: plumbing, heating, electricity, weatherproofing, and structural soundness. A leaky faucet is not a habitability violation. A broken furnace in January is.
Landlords are also responsible for common areas like hallways, stairwells, laundry rooms, and parking lots. Pest infestations, mold from unaddressed leaks, and broken locks on exterior doors fall within the repair obligation. Most state laws require repairs within a reasonable time after notice from the tenant, and what counts as reasonable depends on the severity. A failed smoke detector gets a shorter window than a cosmetic ceiling crack.
Ignoring habitability problems does more than invite complaints. Depending on the jurisdiction, tenants may withhold rent, make repairs and deduct the cost, or break the lease without penalty. Local housing agencies can also impose fines or order repairs directly.
Handle Security Deposits by the Rules
Security deposits are one of the most regulated parts of being a landlord. Roughly half of states cap the amount, typically at one to two months’ rent. The other half impose no statutory limit.
After a tenant moves out, landlords have to return the deposit within a deadline set by state law, generally somewhere between 14 and 60 days. Most states also require an itemized statement explaining any deductions, such as unpaid rent, cleaning costs beyond normal wear and tear, or damage repair. Missing the deadline or skipping the itemization can trigger penalties, and some states let courts award the tenant double or triple the withheld amount.
Follow Fair Housing Law
Federal law puts hard limits on how landlords select and treat tenants. The Fair Housing Act prohibits discrimination in renting based on seven protected characteristics: race, color, religion, sex, national origin, familial status, and disability.1Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing and Other Prohibited Practices It covers advertising, screening, lease terms, and day-to-day management. A landlord who charges families with children a higher deposit, refuses to rent to someone because of their religion, or steers applicants of a particular race toward certain units is breaking federal law.
Disability protections carry extra requirements. Landlords must allow tenants with disabilities to make reasonable modifications at the tenant’s expense, such as installing grab bars or widening doorways, and must make reasonable accommodations in rules and policies. A building with a no-pets policy, for instance, has to allow a tenant with a visual impairment to keep a guide dog.2U.S. Department of Housing and Urban Development (HUD). Fair Housing – Equal Opportunity for All
Familial status protections mean a landlord cannot refuse to rent to someone because they have children under 18, are pregnant, or are adopting or gaining custody of a child.2U.S. Department of Housing and Urban Development (HUD). Fair Housing – Equal Opportunity for All Many state and local laws add further protected classes, including sexual orientation, gender identity, source of income, and veteran status.
What a Landlord May Do
Collect Rent and Set Reasonable Rules
The most basic right is to collect the rent in the amount and on the schedule the lease establishes. Landlords can also set reasonable rules governing the property’s use, covering noise, parking, guests, and whether tenants can sublease. Rules that single out protected classes or make the property effectively unusable will not hold up.
Enter the Property, With Notice
Landlords retain the right to enter a rented unit, but not whenever they like. Most states require at least 24 hours’ advance notice, and the visit must have a legitimate purpose: making repairs, conducting inspections, showing the unit to prospective tenants or buyers, or addressing a maintenance issue the tenant reported. Genuine emergencies like a burst pipe or a fire are the exception, and no notice is required. Repeated unannounced visits that aren’t emergencies can rise to harassment and may give the tenant grounds to break the lease.
Screen Applicants
Landlords can screen prospective tenants by running credit checks, verifying income, contacting prior landlords, and checking criminal history within the limits of local law. When a landlord uses a consumer report to deny an application, federal law requires an adverse action notice. That notice must include the name and contact information of the screening company, a statement that the company didn’t make the rejection decision, and information about the applicant’s right to a free copy of the report and to dispute any errors.3Office of the Law Revision Counsel. 15 USC 1681m – Requirements on Users of Consumer Reports Skipping the notice is a common and easily avoided mistake that creates liability.
Pursue Eviction Through the Courts
Landlords can remove tenants who don’t pay rent, violate the lease, or remain after the lease expires. But eviction has to go through the courts. Self-help evictions, where a landlord changes the locks, shuts off utilities, or removes a tenant’s belongings, are illegal in every state. Even when the tenant is clearly in the wrong, the landlord must follow the legal process.
That process starts with a written notice telling the tenant what the problem is and, depending on the type of notice, how long they have to fix it. A pay-or-quit notice gives the tenant a set number of days to pay overdue rent or leave. An unconditional quit notice, used for serious violations like illegal activity or major property damage, requires the tenant to vacate with no option to cure. If the tenant doesn’t comply, the landlord files an eviction lawsuit, both sides appear before a judge, and if the landlord prevails, the court issues a judgment for possession. A sheriff or marshal, not the landlord, physically removes the tenant. Timelines range from a few weeks to several months depending on local court backlogs.
What a Landlord Cannot Do, Even When Otherwise in the Right
Most states have anti-retaliation laws that prohibit landlords from punishing tenants who exercise their legal rights. If a tenant reports a building code violation, complains about needed repairs, or joins a tenant organization, the landlord cannot respond by raising the rent, cutting services, or filing an eviction as payback. Courts treat retaliation claims seriously, and a landlord who retaliates can face penalties and may have an otherwise valid eviction thrown out.
Tax Duties That Come With the Role
Rental income is taxable. The IRS counts rent as gross income, and landlords must report it regardless of amount.4Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined Most individual landlords report rental income and expenses on Schedule E of their federal tax return.5Internal Revenue Service. Instructions for Schedule E (Form 1040) Rental income is more than the monthly check. If a tenant pays your utility bill or provides services instead of cash, the fair market value counts too.6Internal Revenue Service. Topic No. 414, Rental Income and Expenses
Landlords can deduct a wide range of expenses that offset that income, including mortgage interest, property taxes, insurance premiums, repairs, advertising, management fees, legal and accounting fees, and utilities paid on behalf of the property.7Internal Revenue Service. Publication 527, Residential Rental Property Repairs and improvements are treated differently. Fixing a broken window is a deductible repair. Replacing all the windows with upgraded models is a capital improvement that must be depreciated over time.
Depreciation is one of the most valuable tax benefits of owning rental property. The IRS allows you to recover the cost of a residential rental building over 27.5 years using the straight-line method.8Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System Only the structure and its components depreciate, not the land. Depreciation begins the year the property is placed in service as a rental, and it is not optional. The IRS requires you to take it whether you claim it on your return or not, which matters when you sell and calculate your taxable gain.
Where the Landlord Label Does and Doesn’t Reach
Residential vs. Commercial
The rules above apply mainly to residential landlords, who rent living spaces like apartments, houses, and condos. Commercial landlords lease space for business use, including offices, retail storefronts, warehouses, and industrial facilities. Commercial tenants are generally presumed to have more bargaining power and legal sophistication, so legislatures give them fewer automatic protections. Habitability requirements, security deposit regulations, mandatory eviction notice periods, and anti-retaliation laws primarily target residential rentals. Commercial leases tend to be longer, more heavily negotiated, and more likely to shift maintenance costs onto the tenant through triple-net arrangements where the tenant pays property taxes, insurance, and upkeep on top of base rent.
Landlord vs. Property Manager
A landlord owns the property. A property manager runs it day to day. Those are different roles, and many landlords fill both. As a rental portfolio grows, or when a landlord lives far from the property, hiring a professional property manager becomes practical. Managers handle tenant screening, rent collection, maintenance coordination, and regulatory compliance on behalf of the owner. They do not hold ownership or final decision-making authority. The landlord still decides whether to raise rent, approve major expenditures, or sell.
Hiring a manager does not shift legal responsibility away from the landlord. If the manager violates fair housing law during screening or ignores a habitability complaint, the landlord can still be held liable. Choosing the right manager and monitoring their work is part of the job, not a way to escape it.
