MegLee Posted May 15 Share Posted May 15 (edited) Why is my ADU shows 500 sqft TOTAL on the drawing provided by my designer?! What caused this discrepancy? Designer said that's the software generated numbers and that there're "layers I couldn't see"....! And that nothing he can do! 12'5"W X 38'L = 475 shown on detailed drawing - including exterior walls These 2 numbers have to match in permit application. Appreciate any feedback! Thanks!!!

Alaskan_Son Posted May 15 Share Posted May 15 Impossible to say for certain what's going on without a plan file, or some plan view images with dimensions at a bare minimum. Link to comment Share on other sites More sharing options...

See attached, these are "software generated numbers" derived from an OOB factory Chief Architect template file: What software is your designer using?

This is a question for your designer. 2 hours ago, MegLee said: nothing he can do Sure there is. Change 500 to 472. Link to comment Share on other sites More sharing options...
basketballman Posted May 15 Share Posted May 15 Use an area polyline to be sure ... never lies .. Link to comment Share on other sites More sharing options...
Joe_Carrick Posted May 15 Share Posted May 15 Maybe there's a pony wall about 2" thicker that isn't being displayed on the plan. Then if the measurements are to the exterior of that wall you would get the discrepancy. We would need the actual Chief plan file - not a pdf - in order to know exactly.

MegLee Posted May 15 Author Share Posted May 15 Designer's explanation:"All areas mentioned on the right side of page one are accurate and calculated from exterior walls (including all sheathing). That's how the city calculates and that's how the areas are put in.""I have done few rounds of check on my end and confident with the answers and the calculation areas I provided. There are specific ways of measuring & I believe what you are inputting doesn't count all the dimensional layers. You do not see those in the drawings and therefore assumptions are made." Why can he provide formula, numbers to arrive at his conclusion? Measurements on the drawing have to match the total on permit application, right? I saw one which matches exactly. And, how often does one see for-sale houses or ADU listed exactly at 2000, 800 or 500 sqft? Link to comment Share on other sites More sharing options...

Explain your concerns and have him demonstrate how he calculated these areas. That can be done graphically with a polyline that shows the actual area. He should be able to do that quickly.

SHCanada2 Posted May 15 Share Posted May 15 something is missing for information. For the ADU, using the measurements on the plan, which look to go to the framing, it is 722 sq ft. his plan says 750. The perimeter is 137 ft, so the ft "missing around the permiter" is 750-722=28 sq ft divided by 137 ft, which is 0.2ft or 2.4" all the way around. maybe that is the cladding and sheathing, but if it is I'm not sure what it would be, you would have to see the rest of the plans Link to comment Share on other sites More sharing options...
MegLee Posted May 15 Author Share Posted May 15 (edited) My neighbor's permit application shows the detail measurements match exactly the total. See red only. IMG_8132.heic Edited May 15 by MegLee Link to comment Share on other sites More sharing options...
SHCanada2 Posted May 15 Share Posted May 15 sorry I cannot view a heic file. What is your proposed cladding for the ADU, and what is the thickness? Link to comment Share on other sites More sharing options...

MegLee Posted May 15 Author Share Posted May 15 I thought all along these totals are entered manually. And again, how often does one see for-sale houses or ADU listed exactly at 2000, 800 or 500 sqft? Link to comment Share on other sites More sharing options...
SHCanada2 Posted May 16 Share Posted May 16 (edited) that does not match the uploaded pdf earlier which shows: are we talking the same thing here? Edited May 16 by SHCanada2 Link to comment Share on other sites More sharing options...
