Landlord Requirements: Essential Rules and Tips for 2025

If you own a rental unit, you need to follow a few clear rules to stay legal and keep tenants happy. These requirements aren’t optional – they protect you from lawsuits and help you run a smooth business. Below you’ll find the most important steps, written in plain English, so you can start applying them today.

Legal Docs and Lease Basics

First up, the lease. A written agreement should cover rent amount, payment date, lease length, and what happens if either side breaks the contract. Most states require a written lease for periods longer than a month, and it’s a good habit even for short stays. Include clauses on security deposits, pet policies, and who handles utilities. Keep a signed copy for both you and the tenant – a digital PDF works fine as long as both parties keep it.

Next, understand the security‑deposit rules in your state. Some places limit the amount you can collect, often to one month’s rent, and dictate when you must return it after the tenant moves out. You’ll usually need to provide an itemized list of any deductions within a set timeframe, typically 30 days. Following these steps avoids costly disputes.

Managing Rent and Maintaining the Property

Rent increases are another hot spot. Many cities have caps on how much you can raise rent each year, especially in areas with rent‑control ordinances. Before sending a notice, check local limits – they’re often expressed as a percentage or tied to inflation. Give tenants proper notice, usually 30 days for a modest raise, but 60 days if the increase exceeds a certain threshold.

Maintenance isn’t just a nice‑to‑have; it’s a legal duty. Keep the property safe and habitable by fixing plumbing, electricity, heating, and structural issues promptly. Provide a clear way for tenants to report problems, and respond within the timeframes required by state law. Regular inspections (with proper notice) help you catch issues before they become big expenses.

Finally, screen tenants carefully but fairly. Run credit and background checks, verify income, and ask for references. However, you can’t discriminate based on protected classes like race, religion, or family status. Follow the Fair Housing Act guidelines to avoid legal trouble.

By covering leases, deposits, rent limits, maintenance, and screening, you tick the major boxes for landlord requirements in 2025. Keep a checklist handy, stay updated on local law changes, and you’ll run a rental business that’s both profitable and compliant.
