Submetering for less.
An HOA that runs itself.
Guardian sells submetering only. Fourplex is an all-in-one solution — submetering plus dues, documents, meetings, website, and bank-connected accounting — for less than competitors typically charge for water submetering alone. No unit minimum to clear.
*Exact savings per unit and hardware costs vary by property size. Contact us for an exact quote. 20% savings applies to gateway hardware; other equipment costs may vary. Guardian quote is water submetering only (no autopay, no HOA management). Fourplex includes platform + submetering — an all-in-one solution.
The handoff
The day you hand over the keys shouldn't be the day the headaches begin.
Every new community needs a way to run itself the moment the last unit sells. Without one, the work lands on a few well-meaning neighbors who never signed up for it.
Dues with nobody to collect them
A new board of neighbors inherits a checkbook, a Zelle handle, and the job of chasing every owner every month.
Utilities split by guesswork
Master-metered water and trash get divided evenly — so the careful households quietly subsidize the heavy users.
Compliance no one owns
Annual meetings, reserve studies, and state filings fall to whoever volunteered last — until a deadline gets missed.
The package
Three things, set up before the first resident moves in.
One partner, one install, one platform — the hardware in the walls and the software that runs on it, bundled together and priced for small communities.
Submetering hardware for less
We size and source per-unit meters for water, sewer, and trash, and give your plumber the install spec — 20% less on gateway hardware than Guardian as of June 2026. 20% savings applies to gateway hardware; other equipment costs may vary. A Fourplex technician commissions the gateway after install.
Low-cost billing, no unit minimum
Usage-based billing reads each meter automatically and charges every owner on autopay — 60% less per month on billing fees per unit than Guardian's submetering-only quote for a 4-unit building (as of June 2026), with no unit minimum. Conservice won't quote under 25 units and Minol USA under 50; we'll set up a project of any size.
A self-managed HOA platform, included
Dues collection, a shared board inbox, documents, meetings, custom email and website, and bank-connected accounting — the whole self-managed HOA toolkit, bundled in so the new board starts day one with everything handled.
Hear it from a builder
“Every vendor I’ve used has been expensive, and difficult to handoff.”

Working together
Join at any stage.
Best before the pipes go in.
We'll meet you wherever the project is — planning, under construction, or nearly complete. The smoothest path is looping us in early so submetering is designed into the plumbing, not retrofitted later.
Loop us in
We can join at any stage, but ideally before construction starts so the plumbing is laid out for submeters. We provide the spec and requirements your team needs.
Your plumber installs
Your existing plumber installs the meters to our spec during normal rough-in — no special crew, no separate subcontractor to schedule.
We commission the site
A Fourplex technician visits to verify installation and connectivity, then sets up the wireless gateway so usage transmits to Fourplex for billing.
HOA goes live
We stand up the HOA platform — dues, documents, meetings, and resident onboarding — so the board inherits a community that already runs. Once the HOA is established, we offer a free onboarding call for your homebuyers to guide them through setup and get everyone on the platform.
