It is not illegal. Check your lease agreement and any emails between you and the leasing agent. If you have been misled, you are free to ask for comeuppance. Otherwise, you're wasting time and money. MPrevious tenants might have been dirty, or your landlord may have not done their scheduled extermination. But don't be too upset. You just moved in. These things can be fixed.

it actually is against the law. regardless of what their contract says. Hes renting not buying. as a landlord you have to do everything as of outside maintenance, plumbing, and things such as bugs. if he would have bought the home that would have been different.

whether or not it's illegal can depend on the state. some places it's just normal sadly.

if you're not a lawyer... you should be. you're good at that

Also as your girlfriend is pregnant you need to make sure the place is safe for her and your baby.

If it can be proven that the landlord knowingly rented the property with a pest problem, then the lease can be broken with no penalty. If the landlord is asked to fix the issue, they have a reasonable amount of time to do so, and if they do not, the tenant can potentially take care of it themselves and hold back rent or sue for compensation, or they can hold back rent until the issue is resolved, they can not break the lease with no penalty. Ultimately it would depend on what their contract said, if it is poorly written there may be loop holes and wiggle room, if it is written up properly, then both the landlord and the tenant should be protected. I spent weeks writing up the lease agreement for our tenants to ensure that they would feel safe and comfortable with it and that my husband and I wouldn't get screwed over too bad should we end up with a horrible tenant (you can only do so much background checking)

As other people have said, legality depends on state/country. In California, you cannot break a signed lease for any reason. If you do, you can legally be held responsible for rent until the landlord re-rents it (though the landlord must be able to prove they are actively trying to rent it out). And the landlord may not be legally obligated to pay for an exterminator, but a good landlord will (especially for a new tenant). My dad does property management and believe me, the laws regarding renter/landlords are not simple (or uniform across the country). The good news is, for the most part, the law favors the renter and there are many agencies (at least in California) that do inexpensive or pro bono work to advocate for tenants.

If your property is inhabitable due to pests or other issues a lease can be voided after going through the proper steps especially if you can prove it was infested before you moved in and kept a secret. You may have to get the courts involved if the landlord is stubborn and refuses to fix it or let you walk away but it can be done. Most people prefer to withhold rent instead of having to move all over again Many people in California use the city health inspectors to allow them to withhold rent A tenant did it for two years at a property the company I work manages purposely breaking things on the life and safety list and then calling the inspector so that they didn't have to pay rent

if you're going to do this make sure you do not do it over the phone all emails and text messages so you have written proof of the interaction

They wouldn't have moved in if they knew. With his girlfriend being pregnant I'm sure that would be one thing they were looking for to make sure the property is suitable for them. I think this needs a followup to explain!
