I have a section of mud sill near a crawl space entry door that has suffered severe dry rot due to rain intrusion. I need to cut out and replace about 3 feet of mud sill. This will require removal of two closely spaced studs (5" apart and about 22" tall), resulting in a horizontal span of about 47" between the remaining studs (one stud bay is wider than normal due to the crawl space entry).
The wall above this cripple wall is single-story but peaked and covered in stucco (considered heavy construction by the seismic retrofit plan sets).
Can I get away with removing these two studs, temporarily, while replacing the mud sill, without adding jacks or other temporary supports? If not, what type and capacity of jacks would I need?
In the following photo, the two cripple studs to be temporarily removed are marked by green arrows. The portion of mudsill to be replaced is marked by blue arrows. The red arrows show the 47" temporary span that would occur once I remove the middle studs. After the rotten mudsill portion is replaced I would reinstall the two studs.
