How Much Is the Fine for Renting an Illegal Apartment in D.C.?

Sometimes, when people rent out a space for the first time, they make mistakes. It’s not that they meant to do anything wrong—they’re just trying to make the most of the space they’ve got. After all, if it’s sitting there unused, you might as well make money off of it, right?  But if that space wasn’t approved for living or doesn’t meet the city’s safety rules, you might be crossing into risky ground—legally and financially. So, what happens if you get caught? How much is the fine for renting an illegal apartment?

In this guide, we’ll walk you through what actually qualifies as an illegal unit, the penalties landlords can face, and how you can take steps to make your property compliant. Let’s get into it. 

Main Takeaways

  • To answer, “how much is the fine for renting an illegal apartment in Washington, D.C.,” fines for renting an illegal apartment in Washington, D.C. range from $2,000 to $4,000 for a first offense. The exact amount depends on the severity of violations, including missing a Basic Business License (BBL) or a Certificate of Occupancy (C of O). Repeat offenses lead to escalating penalties.
  • Beyond fines, landlords may face eviction orders, legal action, and liability for tenant damages. If authorities deem the unit unsafe or non-compliant, landlords could be forced to shut down the rental and compensate tenants for relocation.
  • To avoid fines, landlords should obtain proper licensing and ensure compliance with D.C.’s housing regulations. This includes securing a BBL, scheduling a property inspection, registering with the Rental Accommodations Division (RAD), and obtaining a Certificate of Occupancy if required.

As property management in Washington, D.C., we can tell you that the fine for renting an illegal apartment in Washington, D.C. depends on a few things. For instance, it depends on how many units you’re renting, whether you have the right licenses, and how serious the violations are. However, to keep it simple: if you’re caught renting out an illegal unit in D.C., you could be looking at a fine between $2,000 and $4,000 just for a first offense. Of course, this can vary depending on the severity of your violation. Either way, it’s a notably big chunk of money. And if you keep operating without fixing the issue, the fines can stack up fast.

Now, the exact amount depends on a couple of things—mainly the type of rental and the paperwork it’s missing. In D.C., landlords must have:

  1. A Basic Business License (BBL) – This D.C. government document states that they have allowed you to rent out property.
  2. A Certificate of Occupancy (C of O) – This proves that the space you’re renting out—like a basement or separate unit—is safe and up to code. Not all rentals need this, but many do, especially if you’ve made changes to the property.

If you’re missing one or both of these, that’s when the fines come in. And believe that D.C. doesn’t play around with housing violations.

What Is Considered an Illegal Apartment?

An illegal apartment is basically a rental unit that doesn’t follow your city’s building or zoning rules. This could mean a few things. Maybe it was built without the proper permits, it’s missing important things like windows or ventilation, or it breaks safety rules. These types of rentals often start as well-meaning home improvements but end up crossing legal lines.

Beyond building codes and rental licensing, zoning laws are also a major factor. Some spaces may meet safety requirements but still violate zoning restrictions that prevent residential use in certain areas. Even if a unit looks livable, failing to comply with zoning laws can result in fines, legal action, and forced closures.

Why Are Illegal Apartments a Problem?

Perhaps you’ve set up a rental in your basement and you’re wondering—what harm could it possibly do? It feels safe, it’s affordable, and you even share a few amenities with your tenant. So why is it a problem?

Let’s break it down:

1. Safety Risks & Lack of Emergency Access

Imagine that the person living in your basement has no proper exit. If a fire breaks out, their chances of escape are slim. They would be completely, utterly trapped. Needless to say, you want to prevent this outcome at all costs. That’s why you need to have your rental certified as being safe (which we’ll get into later).

2. No Insurance Coverage

By definition, keep illegal apartments under the table, without official certification. And because they’re unofficial and unapproved, it’s almost impossible to insure them. If something goes wrong—fire, flooding, damage—you’ll likely be left to foot the entire bill on your own.

3. Risk of Fines

Once local authorities find out you’re renting out an illegal unit, you could be slapped with serious penalties. The fines can stack up fast—and typically, they’re not cheap.

4. No Legal Protection

Illegal tenancy can start off smooth, just like a relationship in the honeymoon phase. But things can get complicated quickly. Say your tenant stops paying rent—you won’t be able to go through the standard eviction process without facing legal trouble of your own. In some cases, the law might even side with the tenant.

Even if you pay the fine for renting an illegal apartment, that’s rarely the end of the story. Renting out an illegal apartment can trigger a chain reaction of legal, financial, and personal complications, including:

1. Forced Evictions and Unit Closure

Once the authorities deem your unit illegal, they can order you to evict tenants immediately and shut down the rental. That means lost income—and sometimes, legal battles if tenants push back.

2. Liability for Tenant Damages

If you have unsafe living conditions (like a lack of fire exits or ventilation) that injure a tenant or damage the property, any involved parties may hold you legally liable. They could even sue you. Then, the court may force you to pay for their losses and hospital bills. 

3. You Could Be Forced to Pay for a Tenant’s Move

Even though D.C. doesn’t have an exact rule for this, in some places like California, landlords have had to pay tenants up to six months’ rent to help them move out of illegal apartments. Why does this matter? Because if your unit isn’t legal and your tenant complains—or worse, takes you to court—you could deal with similar issues. The courts may order you to pay for their moving costs or face other serious penalties. It’s just one more reason to make sure your apartment is legal from the start.

4. You Probably Cannot Insure It

Since the apartment is illegal, there’s a good chance you won’t be able to get insurance for it at all. And without coverage, if something goes wrong—like a fire, flooding, or any kind of damage—you’re on your own. That means you’ll have to handle all the repairs and costs out of your own pocket, which can get really expensive, really fast.

How to Make Your Apartment Legal

Now that we’ve covered the risks of renting out an illegal unit, let’s talk solutions. Legalizing your apartment is not just about avoiding fines—it’s about becoming a responsible, recognized landlord in Washington, D.C. The process might sound intimidating. However, it’s very doable once you know what’s required. Here’s how to get started.

1. Get a Basic Business License (BBL)

If you want to rent out your property legally in D.C., you need something called a Basic Business License (BBL). It’s a piece of paper from the city that confirms you’re allowed to be a landlord. You can apply for it online through the Department of Licensing and Consumer Protection (DLCP)—and without it, you’re basically renting illegally.

2. Schedule and Pass a Property Inspection

After submitting your BBL application, your property must undergo an inspection to ensure it meets D.C.’s housing codes. The Department of Buildings (DOB) will conduct it. 

3. Register with the Rental Accommodations Division (RAD)

Once your BBL is approved, it’s time for the next step. You must register your property with the Rental Accommodations Division (RAD) of the Department of Housing & Community Development. This registration determines if your property is subject to rent control laws.

4. Obtain a Certificate of Occupancy (If Required)

If you’re renting out a unit that you’ve newly constructed or significantly altered, you might need a Certificate of Occupancy. For example, if you convert a basement into an apartment, you could need it. This certificate verifies that the space is safe and suitable for residential use.

How to Check Your Apartment’s Legality

So, you’ve done the work—applied, fixed things up, even passed an inspection. But is your apartment actually showing up as legal on city records? It’s smart to double-check, just to be sure. Here’s how you can do that:

  • Look Up Your Property Info Online

D.C. makes it easy to search your property’s license status. You can visit the D.C. Business License Lookup tool to check if your address has a valid rental license.

  • Make Sure the Unit is Approved for Residential Use

If you converted an area into a living space, did you get it approved? If not, it could potentially be considered illegal. Even if it looks livable from a glance, that’s still not a formal assessment. You can call the DOB or visit their website to check if the space meets code requirements.
