About this paper
Updated .

Plumbing Across L.A. is a neighborhood paper about the plumbing in Los Angeles houses, arranged by neighborhood and by the age of the house.
What it is not
It is not a plumbing contractor. It does no installs or repairs, takes no leads, has no plumbers, and sends nobody to your door. It does not recommend named contractors. When a job needs a licensed hand, these pages say so and show you how to check a C-36 license yourself.
The web address reads like a contractor's because that is what the address was already called. This paper has nothing to do with any earlier site that used it, and it can't answer for anything that appeared there.
How it is written
The pages are built from official sources: LADWP, LA Sanitation, LADBS, the California State License Board, utility water reports and city historic-district pages, with dates where a figure can change. Neighborhood and house-age history comes from places like the LA Conservancy, the National Park Service and city preservation offices. Sources are linked next to the claim and listed at the foot of most pages.
The pages are written and checked by the editors with AI tools. Nobody here has inspected your house, tested your water or visited your street, and no page should be read as if someone had. What's general is marked as general, and where this paper couldn't confirm something, it says so.
What to do about a mistake
Rules and rates change, so trust the agency over this page when they disagree. Corrections aren't taken by form, and there are no contact details on this site. The linked agency page is the place to confirm anything that matters to your house.
Money
