The short answer
The median build year in Grand Terrace is 1976, which is copper territory and sometimes copper with polybutylene in part of the run. Normal supply is 45 to 80 psi and under 40 psi is low, so a gauge on an outside tap settles whether this is a supply problem at all.
Sources: US Census Bureau, American Community Survey 5-year estimates, table B25035; normal and low ranges as published by Grundfos in its homeowner guide to low water pressure.
Grand Terrace has 4,543 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1976 — the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.

What 1976 tells you about the pipe in Grand Terrace
Housing of this vintage generally means copper as the usual supply material, so corrosion narrowing the pipe is far less likely. In houses of this era a whole-house pressure drop points at the pressure-reducing valve, the main shut-off, or the supply side of the meter rather than at the pipe itself. More on 1970s supply pipe.
61% of occupied homes in Grand Terrace are owner-occupied, 8 points above the CA figure of 53%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

Whole house is a call; one tap usually is not.
