buzzsaw204 Posted April 4, 2022 Share Posted April 4, 2022 CA only have Basement floor to have NO option, but just Concrete Slab floor. what is the efficient or Best method to draw Basement Floor with Wood Joist construction, Basement Level (0) with Crawlspace. my work-around, current method, is.... Level (0) to be Crawlspace, no floor construction, Level (1) to Basement Floor using Floor Framing (2x10, etc..) Level (2) to be Main Floor (above grade)..using Floor Framing (2x10, etc..) Level (3) to be Second Floor (2nd-strory)..using Floor Framing (2x10, etc..) Link to comment Share on other sites More sharing options...

BTW your 82" stair clearance is supposed to be from teh front of the next tread up and you don't fall within IRC code anyways. You don't share your location so it might qualify there but seeing as the majority of are at least 76" most 80"or more I don't think it will work.

VHampton Posted April 4, 2022 Share Posted April 4, 2022 A landing could be used over the slab. Why anyone would want to build a basement without a slab however is curious. The thermal break between the heated basement space and cooler soil temperature will create vapor. It's a recipe for dampness, then mold, and possibly rot, unless the framing is treated. Edit... unless this is an elevated floor which has no direct contact with the soil - and with fresh air flowing below the framing. My guess is yes based on your cross section. ...and yes - Ryan's observation on the stairs is absolutely correct. Edge of tread (nosing) to any overhead surface. 80" is the minimum allowed by IRC regulation. Link to comment Share on other sites More sharing options...

Essentially, it's a Crawlspace as your basement floor construction with Wood Joist framing or Open-Web floor trusses, instead on Slab on compacted fills. makes warmer floor for cold climate.

VHampton Posted April 4, 2022 Share Posted April 4, 2022 Very interesting. I've watched many episodes of Holmes on Homes and I believe they had a project like that. ...anyway, it looks like you may have a great solution thanks to Ryan. Link to comment Share on other sites More sharing options...

Me too, I am in Ontario just east of Toronto, and I have never seen this style of floor except for something like a cottage. Link to comment Share on other sites More sharing options...
VHampton Posted April 5, 2022 Share Posted April 5, 2022 Code in CA seems to suggest that frost heave may occur. When basement foundation walls are warm, vapor build-ups. Extreme cold = Freeze = heave-ho. Interesting. code Link to comment Share on other sites More sharing options...

I don't see an issue with putting the garage on level 2. Chief is designed to build rooms. A crawlspace is a room on the 0 level in your case, what you are calling a basement is actually a semi-subterranean floor with a retaining wall and not a true basement, if your garage is above that for part of it then on the level 1 you would just adjust that room below the garage that will be "unexcavated" to change where the "floor (top of footings) and ceiling (slab for garage above) would be located. No one ever said that hillside projects were easy to design/draft. Link to comment Share on other sites More sharing options...

VHampton Posted April 5, 2022 Share Posted April 5, 2022 Yep. I see the frustration. It is possible to build a first floor as a Pony Wall. By lowering the first floor elevation, that will allow a lower elevation for the floor framing. No walls on the foundation level, even though the cross section shows otherwise.

VHampton Posted April 5, 2022 Share Posted April 5, 2022 That works. Obviously the program isn't quite set up to build more than one level below Floor 1, but it's possible The method in the plan which had been attached was set up so that the ground floor is still on Level 1 in Chief.
