Exterior walls not aligned vertically between stories

Just wondering if a second story exterior load bearing wall is inset by about a foot from the first floor wall and resting on the joists (like the opposite of a cantilever), is this something that would require a structural engineer to sign off on or is this something mandated by local building codes? I cant seem to find any standard details of this condition but have attached a sketch.
Thanks,
Michael

I would think a second floor wood foundation for a brick wall is not a good choice. Wood can move due to temperature and humidity changes. Mortared bricks can't. You will end up with cracks in the brick wall. Why don't you want one continuous brick wall?

Yes I would say this is a job for a structural engineer.
Not just approve it but design it.

You did not say why you wanted to do this seems but like a lot of trouble.

Zoning requirements. This is for an addition above a garage. The ground floor setback is 1m (and has been built to 1.2m) and the second storey setback is 1.8m (so we would have to set it back 0.6m from the existing ground floor wall)

If it's not required I think you would want an Engineer because of the unusual design/construction.

Common sense would prevent you from constructing a wall like this. Talk to your zoning department because on the surface it makes no sense. If not satisfied , file a request to not meet this zoning regulation and bring a structural engineer with you. Where are you located?

Have you investigated a zoning variance.

Usually if the zoning department is reasonable and your neighbor is OK with it it will go through.

If you do not get along with the neighbor then you have a problem.

Thanks for the help, I did propose applying for a variance to the client but she was strongly against it due to the costs, the extended time frame and having it all being dependent on her neighbors... Suffice to say the project has been aborted
