My husband and I just bought a duplex in Ohio. Both sides already had tenants.
A few days after closing, the duplex started having major sewer issues. Sewage and drain guys needing to come out to the property multiple times in multiple days. To make a long story short, it needed 2 new main sewer lines which cost well over $10k. While the new lines were being inspected, the city stated that the duplex only had 1 water line/meter coming in (which we knew about and pay the bill for) and that the property must have 2, so they were going to look into contacting us about having to add an additional water line to have both units be separate. I don't see any reason for this and have never heard of this.
Is this how it goes sometimes? I feel like we are getting screwed left and right here, and that nothing is going right. Do all duplexes need all utilities separate? Is this just a particularly nit-picky city trying to get extra money?
City building people have their own agenda. I give it a 50/50 chance you don't need to do that.
Ask them to cite the code that requires each side of the duplex have water / sewer then look up that code. If that were the law, they should have been built that way originally. See if you might be grandfathered. If need be, check with a local attorney that specializes in building issues.

Sewer was something you should have scoped when buying. You always check that because you have no other way of knowing it. What is the property zoned as? Is it a converted single family or did they make it a duplex illegally? As Greg said it's up to the city and what laws are there.

Right. Scopes are worth every penny

Agree, I didn't know that was recommended during inspections and purchased a duplex years ago with near immediate failure due to break in sewer line outside. Sucked. OP I'm sorry this happened to you also.

I have had buyers this happens to as well, it is a pain. I always recommend sewer scope. A very small price to pay the assurance or funds to your closing costs to repair the line or whatever you need. Knowing Ohio, that does not sound right that you need to have separate water meters. Some areas even require owners to pay for water/sewer even if on the lease it is tenants responsibility. If I am wrong, someone educate me and source it please. But no that doesn't sound right. I'm curious to know how that plays out
You would have easily seen that the sewer line was in need of replacement if you had scoped it during inspection. It also would have been obvious that there was only one water line/ meter for 2 units by simply counting the number of water meters. A lot of jurisdictions are requiring separate water taps for each unit in duplexes now, so this is also something you should have looked into. It can be up to $100k to add a new water tap in some jurisdictions around here, and often is at least $40k, so it’s definitely something I recommend buyers look into before purchasing. No offense but it doesn’t seem like anyone screwed you here, but rather that you failed to do proper due diligence. These are things that buyers normally check during their due diligence and inspection time period, prior to closing, and then negotiate price accordingly. Expensive lessons learned.

Hi Steve,
I was told to add sewer line inspection to the home inspection if the house is 50 years or older. Is scoping the sewer something you do regardless of the age of the building?

most agents highly recommend it to the buyers bottom line.. Myself when buying off market If there is a PVC riser then the sewer line has been replaced at some point.. but if its not PVC then its clay and as @Marcus Auerbach mentioned your going to have root intrusions soil moves clay breaks etc etc.. just running water down the shower and flushing toilets is not going to identify the issues generally.. its when the homes get put into service where this will pop up..

You should have gotten a sewer scope
Thanks for your reply everyone. I've bought 5 houses in my lifetime from 4 different agents and no one has ever suggested scoping out a sewer line. I honestly didn't even know that was a thing that people did during the inspection period. I know now!
I also didn't know that I needed to check out codes of an already in place duplex. I've never heard of both sides needing their own main water line. I now know that as well.
Thanks for keeping me humble and realizing that these were my errors of being negligent and uneducated (despite constantly listening to podcasts daily during any free time).

If the sewer lines were an issue prior to the sale and the seller didn’t disclose, and you have hard evidence that this was an ongoing issue, and that the seller knew about it and didn’t disclose, you may be able to pursue that further… it might be worth talking to an attorney… but again if you had an inspection clause and chose not to scope the sewer line, then that would reflect negatively on you because you would have had the opportunity to uncover these issues yourself then, and didn’t. Depends on the disclosure laws there and whether it is a “caveat emptor” state or not. I believe Ohio is caveat emptor in which case the seller does not have to disclose a defect that can be uncovered during inspection. It can be hard to win a failure to disclose case in a caveat emptor state unless you can prove fraud on behalf of the seller basically, that they covered it up preventing you from finding it during inspection. Always better to avoid these situations by performing adequate due diligence, which now you know, and knowing is half the battle. Good luck, I hope the property still works out for you in the long run!

Not so fast!!! Put that spoon down and back away from the humble pie!!
As unbelievable as it seems to our guys out West, in some of the Midwest markets, a sewer scope is not a thing! Ohio might be similar to Milwaukee and if you write a sewer scope into your offer you might as well save the paper.
We close 100+ transactions per year and I have never seen an offer with a sewer scope. And I should add, I am keenly aware of the cost, I had the pleasure of replacing a sewer lateral on one of our rentals - and it was almost 15 feet down!
The way it works in Milwaukee is that the home inspection flags tell-tell signs and then you bring in a sewer scope as a follow-up. We have a ton of 100 year old houses and the sewer lateral is typically made 3ft clay tile sections. Tree roots are an issue, they grow into the gaps and then start catching solids. I have a few properties where roots need to be cut every other year.
About the city demand for a separate water line. Milwaukee has more duplxes than any other city in the US (66,000) and the typical setup is one water lateral and one sewer lateral. And one water meter, so the owner eats the cost of water and sewer. Not sure why you need 2 of each or why the city would see that as necessary, but in the long run it benefits you because now the tenants pay their own sewer and water.

It's not something we put in our offers here per se, it's just done as part of inspection as an a la carte add-on that buyers can choose to do or not, just like radon, flow rate or water quality test if there is a well, etc. Unless a buyer waives their inspection, they have a right to inspect all the systems of the property including plumbing which includes the sewer line. I've seen sewer lines that cost $100k to replace so it's definitely something that I recommend buyers check. It's only $100-150 so kind of a no-brainer when a new sewer line can be anywhere from $5-100k.

Jay and Steve, in a way, you can. The way it works here is if the general home inspection has concerns about the sewer, they recommend a follow-up inspection and that can be a sewer scope. Our home inspectors don't even have the equipment for a sewer scope (and my guys are heavy on tech & equipment).
It's just not a common problem. I don't recall a client having issues and it is never a topic at KW trainings and I hear about all sorts of rare issues, like DNR disputes when building a dock or bluff erosion on Lake Michigan and the associated lawsuits.Not about sewer lines.
I suspect this has to do with our subsoils, mostly clay, silt and loam. When you see a pipe buried in clay, you almost don't need a pipe. Expansive solids come with their own issues though: we deal with of outside pressure-induced cracks in basement walls, probably a non issue out West?

In Ohio, most older duplexes were built with shared utilities, and separate water meters are not typically required unless you’re doing major renovations or trying to reclassify the property. Some cities, though, have started enforcing stricter codes when any significant work is done, which might be what’s happening here. It’s worth asking the city to show you the exact ordinance that requires two meters. Sometimes, they "recommend" things that aren’t actually mandatory. Many landlords in similar situations keep the single meter and bill tenants back instead.
Offers contingent on sewer scoping is nice-to-have in some markets, a requirement in others. Really best to ask local investors that you trust on what's "normal." I'd love to require all the contingencies but then I'd probably never buy anything.
That said - if you don't inspect something then you better expect some probability that you end up having to replace. If you can't afford a sewer repair/replace you shouldn't buy without scoping!
@Lauren Adair
That sounds incredibly frustrating—I'm sorry you're going through this right after closing. Unfortunately, some cities do have strict utility requirements, especially if the property is zoned for true duplex use. It’s worth checking the local code or speaking with a real estate attorney to clarify if the dual water line is legally required or just a recommendation. You're not alone—many investors face these surprises early on. Hang in there, it gets easier with time and experience!

this cast iron pipe was not leaking any sewage, It was acting like a canal, flowing down hill. No odor reported. Fortunately this is a raised foundation. It is common for them in crawl spaces to break from the top. I suspect the air causes more decay than soil. The owner legitimately could be unaware of this level of damage. Granted this can be caught by a good home inspector; one that is willing to check out the pipes in the crawl space.
Swapping the entire sewer to ABS is not cheap. It is a lot of work.
I encourage thorough due diligence. This includes sewer, septic tank, fireplace (I had one recently that the mortar was closer to sand than cement), foundation (if there is any concern), hvac, roof (if there is any concern), permits, easements, etc.
Checks are fairly cheap, repairs can be very costly.

I recommend all clients get the sewer lines inspected, even on new construction here in Texas. You never know what you will find.
