 Posted: Mon Feb 02, 2009 12:59 pm Post subject: Question about adding a second story to a block house |
    |
|
I want to add a master suite upstairs to my 1959 Florida single-story concrete block house. Two of the walls of my intended 2nd story will be over walls that were not part of the original exterior outline of the house, so they probably don't have a poured foundadtion directly under them, just the concrete slab.
Is it going to be necessary to somehow get under those interior areas to put poured footers or some other form of foundation supports along those walls? How on earth would they do that?
Also, when doing a major rennovation like this, is it possible to continue to live in the house if you're willing to put up with the inconvenience, or is permitting a problem?
Thanks for your time!
Best regards, Warren |

I think Florida has some fairly strict building codes for residential construction - mostly centered on hurricane resistance. You really need to find a local architect or engineer who can answer your questions.
You can add a footer under existing construction. It's called underpinning. You basically build the foundation/footer in small sections.
Living in the house during construction will really be up to you. Typically the code does not address the matter. You might have issues more from the local housing inspector or health inspector..... but the building inspector will probably not be an issue. What you may want to consider is if moving out will allow the contractor to work quicker, thus shortening the entire construction schedule. |

I would look at the reality of cutting out either the slab edges, or underpinning the slab edge with drilled and epoxied dowels tied into the new footings.
There is a chance the rest of the house is fine, as the tie beams spread the loads rather well. But an engineer will need to verify that the width of the footings have the required cone to distribute the load. Normally 20" width is sufficient as long as the footing is code min. 20 deep.
An engineer that is creative should have little problems. |

| They are correct there should be little problem with redesigning for your proposed master if you obtain a professional. If you would like some engineering assistance please call me. (949) 770-9967 X102 |
