I am not personally aware of such a standard that is used in every state, but it is worth checking with the state authority to see what standards are applicable in the state.

That being said, I would ask if the home is being prewired for alarm services or not. If so, you could find an avenue to ask about other things. My sister and her husband just bought a new house outside of Dallas and it is coming prewired for RG6, wired alarm and CAT-6 ethernet.

The marketing brochure calls it "custom home" but he only gets to talk to
the developer's "design consultants", i.e. sales people.  The developer
has a sales center and pre-set upsell options, kitchen countertop
choices, carpeting, etc. He never talks to the architect, general
contractor, electricians or construction crew.

He paid for a finished basement option, which means most of the basement
will have sheetrock finished walls. So the first cable, fiber or
telephone utility will be cutting holes in the new sheetrock. I was trying
to avoid needing to cut brand-new sheetrock or fishing wire
through walls.

The design consultant's answer for everything was 5G ... 5G ... 5G. No
more ugly boxes on the house, everything will be wireless. There is a
special deal if he signed up for 5G wireless service before his house was
finished.

For something "no one ever asks about," the design consultant seemed to
have a lot of prepared sales pitches.


Acting like a dumb homebuyer over the Thanksgiving weekend I did notice
the model home had a demarc box on the garage outside wall.  The garage
in the model home is used as the builder's office, so it may not be how
the built homes are setup.


A new version of ANSI/TIA-570 (residential wiring standard) is due this
year. In the old days, a minimum of one wired telephone outlet was
required. I was just wondering if there was new 'standard' for demarcs in
new residential construction.  But it sounds like there isn't. Draping
cables around the sides of the house.
