Here's the thing: a lot of tenants in Hammond believe their landlord can raise the rent whenever they want, with as little notice as a text message or a casual conversation.
That's not quite how it works, and understanding the real rules could save you from a nasty surprise when your lease renewal rolls around.
The short answer is that Indiana law—and Hammond's local ordinances—require landlords to give you proper written notice before your rent increases take effect. But the timeline matters more than you'd think, and getting the details wrong can actually affect whether a rent increase is even legal.
What Indiana Law Actually Says About Rent Increases
Look, Indiana doesn't have a statewide rent control law that caps how much your landlord can raise your rent. That's the reality in most of Indiana, and Hammond follows the same framework. Your landlord can technically increase your rent by any amount they want—there's no percentage cap or limit. What they can't do is skip the notice requirement.
Here's what the law actually says: Under Indiana Code § 32-31-1-3, a landlord must give you written notice of any change to your lease terms—including rent increases—before your current lease ends. The statute requires that notice be given in writing and delivered to you in a manner that's actually noticeable.
But here's where timing gets tricky. — which is exactly why this matters
The Notice Timeline You Need to Know
Indiana Code § 32-31-3-3 sets out the minimum notice period for month-to-month tenancies: your landlord needs to give you at least 30 days' written notice before the rent increase takes effect. That 30-day clock starts from when you actually receive the notice, not when your landlord writes it or posts it on your door.
If you're in a lease with a fixed end date—say, a one-year lease ending June 30th—your landlord should tell you about a rent increase well before that lease expires. Most landlords and property managers in Hammond will notify you 60 to 90 days ahead, though Indiana law technically allows them to wait until closer to your lease renewal date as long as they give the required written notice.
The critical detail is this: the notice has to be in writing. A text message, a conversation at the mailbox, or an email from someone without authority to bind the lease probably won't cut it. You want a written notice that's clearly dated and spells out the new rent amount and when it takes effect.
Hammond's Specific Rules and Protections
Hammond, Indiana has adopted its own rental housing code under Hammond City Ordinance, and while it doesn't impose rent caps, it does require landlords to follow proper notice procedures and maintain the property in habitable condition. When a landlord gives you notice of a rent increase, they're still bound by Hammond's housing code—meaning they can't legally increase your rent while ignoring code violations in your unit.
If your landlord tries to raise the rent but hasn't fixed a heating system or dealt with a mold problem, you've got leverage. A rent increase doesn't override their obligation to keep the place livable under Hammond City Code § 14-5.
Honestly, what trips up a lot of tenants is thinking they have to accept whatever number their landlord puts in that notice letter. You don't. You can negotiate. You can propose a smaller increase. You can offer to sign a longer lease in exchange for a lower raise. And if you think the increase is tied to retaliation (because you filed a complaint about code violations, for example), Indiana Code § 32-31-19-1 actually protects you against retaliatory rent increases.
What Happens If Your Landlord Doesn't Follow the Rules
Real talk—if your landlord doesn't give you the required written notice, the rent increase probably isn't enforceable. If you receive notice but it doesn't give you the full 30 days before it's supposed to take effect (on a month-to-month lease), you could have legal grounds to challenge the increase.
Your best move is to keep copies of everything. Save that notice letter. Write down when you received it. If your landlord later claims you agreed to a rent increase and tries to evict you for non-payment, you'll have proof of when you actually got notice and whether it met the legal requirement.
If you're facing an eviction over a disputed rent increase, consider reaching out to the Lake County Bar Association or a local legal aid clinic. Hammond has resources available, and a conversation with someone who knows Indiana tenant law could clarify whether your landlord followed the rules or cut corners. The 30-day notice requirement exists for a reason—it gives you time to decide whether you want to pay the increase, negotiate, or look for a new place.
