OCC1950: "living in" vs. "living out" for "private household service workers"?

Using OCC1950 for 1920-1950 Census samples, I would like to identify those who were “service workers for private households” by “living-in” vs. “iving-out” status. The corresponding OCC1950 codes are 700, 710 and 720. Is such a variable available via IPUMS?

For example, in the Excel file for “1950-1960 Crosswalks between Census Bureau Occupations,” these occupational categories were broken down to “living in” and “living out”.

I believe these were identified using a combination of OCC and RELATE. The detailed RELATE code of 1250 in 1960, and 1251/1252 in 1950, are given to employees of the householder living in their household. 1251 identifies domestic workers, while 1252 (non-domestic employees) is mostly agricultural workers. The numbers I calculated using the microdata do not match up exactly with the number presented in the crosswalks on this page that you referred to, but they are reasonably close if you look only at employed individuals (EMPSTAT=1; see table below). The crosswalks listed on the occupation and industry page were not created by IPUMS - I believe they came from the Census Bureau.
