Widening and replacing basement stairs

Good Morning!

Yes you most definitely need a permit as it is structural. A framing carpenter is your best bet or any carpenter with any framing knowledge. In my opinion widening the stairwell hole losing the floor space may be the best route to go. Keep in mind I have not seen the space personally however.

Have a great day!

Good Morning,

Touching the side wall that is bearing wall is not a good option and may cause problems.

Anyway, you need structural engineer to deeply look at the locations and all the possibilities there are. Even another option needs cutting joists and provide proper beam and support.

First of all this job needs to be done by an engineer and preparing drawings for getting permit and after that start construction based on the approved drawings.

We are structural engineering firm would be glad to take care of your job.

Removing a layer of brick from a common wall probably isn't an option; only possibility is if behind the drywall is a non-loadbearing wooden wall you could gain space from perhaps by turning studs onto the flat. Certainly a permit is required. You will need to have a full understanding of the existing structure and so long as the framing conforms with the rules & span tables in Part 9 of the Building Code engineering is not required. The new stairwell width should satisfy minimum Code requirements.
