Is Penngrove on Septic or Sewer?
Penngrove, California is supplied with water by the Kenwood/Penngrove Water Company, a small private system rather than a city utility. Sewer service comes from the Penngrove Sanitation Zone of Sonoma County. Because Penngrove is unincorporated, building and plumbing permits go through Permit Sonoma rather than a town hall, and its published fee schedule puts a water heater and vent plumbing unit at $20.75 against a $327 minimum trade permit fee. The Kenwood/Penngrove Water Company does not publish a hardness figure we could verify, so we are not going to quote one — if scale on fixtures or short water heater life is the actual concern, a hardness test at the property answers it directly and costs very little. Avanté Plumbing does leak detection, drain and sewer clearing, water heater work, repiping and gas lines across Sonoma County under California CSLB licence #841938 (C-36 Plumbing), family-run since 2004.

Local detail
Plumbing in Penngrove: what's actually different here
Water chemistry, housing age and city rules vary across the North Bay. Everything below is sourced from Penngrove and Sonoma County public records.
Who supplies water in Penngrove?
The Kenwood/Penngrove Water Company, a small private system serving both communities rather than a municipal utility. It does not publish a hardness figure we could verify in the current reports, so we will not put a number on it — the honest answer is that a hardness test at the property settles it, rather than a figure borrowed from a neighbouring system.
Who issues plumbing permits in Penngrove?
Permit Sonoma, because the community is unincorporated and has no city building department. Its published schedule lists a $327 minimum trade permit fee, $20.75 for a water heater and vent unit, $8.26 per water piping unit, $8.26 for a gas piping system serving one to four outlets, and a $257 plan check for a sewer line from the main to a building. Those are county fees, not ours.
Do you need a permit to replace a water heater here?
In unincorporated Sonoma County, yes — Permit Sonoma issues permits for like-for-like water heater replacement, and its published fee schedule lists a water heater and vent plumbing unit at $20.75 against a $327 minimum trade permit fee. Repiping, gas piping and sewer work are permitted too: water piping runs $8.26 per unit, a gas piping system serving one to four outlets is $8.26, and a sewer line from the main to a building carries a $257 plan check. Those are county fees, not our charges.
