This can frequently be stabilized and/or pulled back into alignment with Star Bolts.

This is a common problem with rowhouses in eastern cities with lots of 19th and early 20th c. housing stock.

Contact a local mason that can investigate the structure and not just look at a picture.

‘It’s a complete rehab’. Youre budget 1million or 100 thousand? A potential 50k - 100k rebuild of the front facade would break the budget or delay the wallpaper installation?

To some extent I’m kidding but this isn’t internetable and could be major. Only a local mason experienced with historic masonry will really be able to tell and even then the extent of the damage is hard to know until you start to take it apart.

I definitely don't think using star bolts would bring me the resale I'm going for.

Seen it all the time and short of rebuilding the wall (likely structural), the star bolts/plates are the best thing to stabilize the wall. Not uncommon to see on 7 figure plus homes. Bigger resale impact is the fact that the wall is moving away from the home.

I would be more concerned that the building is not vertical.

This frequently has nothing to do with the integrity of the rest of the structure at all. It has to do with party wall to party wall joists with solid masonry front wall that wasn't tied into the joists well enough, but it usually is not a difficult repair. But its why you will see row houses with intact facades and shell interiors and row houses with intact floor structures where the facades collapse. Obviously this needs to be inspected, but in a historical row house this is a not uncommon issue and isn't necessarily indicative of a difficult and costly repair.

Or it can mean the entire front facade has to come off. It all depends on the original construction and what has happens in the ensuing centuries.

I have had many contractors and inspectors that were less helpful and charged a lot more than those on the Internet.

You probably got what you paid for., including liability.

Mark's right--strangers on the internet have zero liability--you have no recourse if you take their advice and then the house falls down. This is too important an issue to depend on the views of someone who hasn't inspected the house in person.

Strangers on the internet do not replace a licensed inspector/engineer/contractor.

However they can provide some personal experience with similar situations. If one has never seen the bowed wall of a masonry row house one might assume that by default the entire house is on the verge of collapse or should be condemned. If a stranger on the internet can say that it could possibly be a relatively common and not expensive problem to remediate, I don't see how that additional information is a negative. Particularly when it's not pretending to replace an inspection.

You mean . . . you can't believe everything you get from the internet??

Do you ever say anything that isn't smart assed and non contributory other than "You shouldn't ask on a forum" in a discussion forum where people are supposed to be able to ask questions? It's troll behavior.

Read the second comment in this thread, it is the best advice offered in this thread, and it was free.

The photo shows something that could be minor, or it could be major and the building is beyond repair and should be condemned. I will not offer a simple solution that will put the OP in peril. If a Houzzer wants advice they ask on the internet; If they want great advice they should get it from a local professional.

Your responses lead me to wonder - why exactly you are on this forum? It's a forum for people to discuss issues surrounding construction. I never stated I was relying solely on what anyone here told me. Perhaps you need to evaluate why you are posting on a forum just to reprimand people for opening discussions.

I am here for my own entertainment and to give good advice so those in construction can untwist their panties.
