Plumbing Inspection in Rancho Santa Margarita, CA
22% of owner-occupied homes in Rancho Santa Margarita have changed hands since 2018. That is an ordinary rate, which makes the ordinary mistake more likely: assuming the inspection covered the plumbing.
The one-paragraph answer
Turnover in Rancho Santa Margarita sits near the middle, with 22% of owner households arriving in 2018 or later. The figure that actually matters is in the standards of practice: a home inspection covers what is visible and operable, and the buried sewer lateral is not.

When Rancho Santa Margarita moved in
Enough houses change hands here for inspections to be routine, which tends to make people incurious about them. The scope is where the surprises are, and it is published rather than hidden.
| Owner households in Rancho Santa Margarita | Share of all owners |
|---|---|
| Moved in 2021 or later | 5% |
| Moved in 2018–2020 | 17% |
| Moved in 2010–2017 | 29% |
| Moved in before 2010 | 49% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 15,958 occupied housing units, of which 11,099 are owner-occupied. This counts when the CURRENT occupant moved in, so it measures recent moves as a share of the housing stock — not a rate of sales per year.
What the inspection will not cover
ASHI asks for the predominant material of the water service, distribution and drain-waste-vent pipes to be described. Predominant is an honest word for a house that has been altered more than once, and it is not a complete answer about any single run.

What it is required to cover
The water heater is covered in more detail than most of the system: InterNACHI takes in the energy source, the venting connections, the temperature and pressure-relief valve, seismic bracing where it applies, and the labeled capacity. What it stops short of is operating any of it.
The rest of what an inspector must do is set out here. It is shorter than the excluded list and it is the half that tells you what a finding is worth.
What to do about it
Ask a contractor what would have to be opened up to answer the question, rather than asking for a number. A quote given without that step is a guess with a figure attached to it.
Everything above comes from documents you can read yourself: the exclusions, the requirements, and why a camera down the lateral is never part of it.
