One way, would be to keep one observation from each household, randomly
sample from the remaining observations, and then merge back to the original
dataset.
For example:
sort hhid
preserve
tempfile tmp
bysort hh: keep if _n == 1
sample 10
sort hh
save `tmp'
restore
merge hh using `tmp'
keep if _m == 3
drop _m
