Pull out tests for epoxied-anchor holdowns in hardened concrete
(OP)
Is there any reference in codes (CBC, ACI) or else indicating the percentage of anchors needing to be tested and the test loads for epoxy anchors in hardened concrete?

As PA and dcarr noted, no requirement by code, but EOR sometimes requires it. Most manufacturers will do the testing or pay for the testing by a local lab. Have done same for Simpson.
Make sure that if a local lab does the testing that they understand how to test correctly.

For residential projects, I guess I can still maintain the required test load equal to 1.25 the maximum design strength of the anchors. And rather than testing 100% of the anchors, I could request testing 25% to 50% of all the anchors. Any other thoughts?

Depending on what you're doing the pull-out test for, and which state you're in, there may be some standards as to rate of loading, max load to test to, duration to hold the load, etc.
I know that around here, both RIDOT (Rhode Island DOT) and MADOT (Massachusetts DOT) have requirements, depending on loading scenario, what the max load is supposed to be, duration to hold load, etc. Both of these DOTs follow some form of ASTM E488 "Standard Test Methods for Strength of Anchors in Concrete and Masonry Elements".
I would say that as long as the ASTM is folowed somewhat, you can set your required load to whatever you feel comfortable with, for as many as it would take for you to feel confident that the anchors were installed correctly.
