Does the floor have to be on the same elevation?

[Tooz]

Doing a major remodel, to include making the Florida room part of the interior: Do I need to make the floor level with the rest of the house? There's a 4" difference, which will require 4" of concrete added to existing Florida room slab (~600 SF)?
The stepdown will be a pain, but cost is an issue...
Thanks in advance,
Tooz

You could frame a wood floor on top of the slab. 3/4” ply over 2x4’s ripped slightly to size. Easy project.

No

You don't need to raise the floor to make it level, but if you stay in the house long enough you will be glad you did.

Generally, I would agree with those who have responded before me and say no.

That said, I do think it is worth mentioning that if this is a multi-family building, accessibility provisions may apply. Is this a SFD? Do you know if the unit is accessible (ADA)?
