especially with pex water pipes nowYes and a ufer/cee is required to be used if available.
UFER ground is an option for new residential house?As rule is written, if qualifying rebar is present in the footing, you must use it, exception for existing construction
If no qualifying rebar 20 feet or more of 4 AWG in the footing makes it a CEE but that is optional.
There is coated rebar as well as some fiberglass reinforcement that sometimes could be used - those obviously are not qualifying for a CEE.

250.50 Grounding Electrode System. All grounding electrodes
as described in 250.52(A)(1) through (A)(7) that are
present at each building or structure served shall be bonded
together to form the grounding electrode system. Where none
of these grounding electrodes exist, one or more of the
grounding electrodes specified in 250.52(A)(4) through
(A)(8) shall be installed and used.
Exception: Concrete-encased electrodes of existing buildings or structures
shall not be required to be part of the grounding electrode system where
the steel reinforcing bars or rods are not accessible for use without
disturbing the concrete.
Where does it say this in code?Keep in mind when you use a ufer ground, no ground rods are required.
Not trying to be a smart aleck but read article 250 requirements for grounding electrodes.Where does it say this in code?
Where does it say this in code?
Got it, but I assume we can still have both ground rod plus ufer?"Where none of these grounding electrodes exist, one or more of the
grounding electrodes specified in 250.52(A)(4) through
(A)(8) shall be installed and used."
You have to read 250.52.

Sure but IMO it is a waste of time and materials with little gain.Got it, but I assume we can still have both ground rod plus ufer?
Are your inspectors not requiring a cee/ufer? In my area, if it’s available, and not used, then you have to chip out concrete to connect to rebarWhere does it say this in code?
And it’s not just residential homes, it’s any occupancy.Is new residential home typically be built with concrete encased electrode? Most of the time I only saw a ground rod was driven by the elec. panel and bond to panel main ground bar but not sure if the panel also bond to concrete encased electrode (if exist)...
