Harmelo Registry: Live For Service & Installation Contractors
For Home Builders & Residential Developers

Every new home you sell arrives with its record.

A permanent record of every system in every home you build — verified by the trades that installed it, attached to the property, and handed to the buyer at closing as an Asset History Report co-branded with your developer mark. The standard of care behind the home, documented at the moment the home is built, signed by the people who built it.

Day 1
Ground Truth, Not Reconstruction
The day the home is built is the most accurate moment in its life. Every record after that is reconstruction. The first record is ground truth — and no future owner can re-create it.

One Link
The Onboarding Workflow
We send you a single link to share with the trades on your developments. They enroll, upload credentials, and start signing records. No software for you to install. No workflow change for your site supers.

Lifecycle Of The Record
The record stays with the home through every owner, every refinance, every transfer. The work you stood behind on day one is the work the home is still standing behind a decade later.

Why It Matters

The most accurate moment in a home's life
is the day it's built.

Every record after that is reconstruction. The first record is ground truth — and only the builder has it. The question is whether it ever gets captured, or walks out the door in someone's truck.

Risk 01
Manuals in a kitchen drawer
Serial numbers on stickers the warranty company can't find. Permits buried in the closing package. The systems are top-of-line. The record is on paper. Year five, no one remembers what was installed or who installed it.
Risk 02
Pre-occupancy work goes invisible
The duct cleaning, the commissioning, the final inspections — all of it happens before the buyer ever walks through the door. None of it shows up in anything they can hand to the next owner. The standard of care is real. The proof of it isn't.
Risk 03
Your reputation can't compound
A home you built ten years ago either holds up or it doesn't. Without a record attached to the home, the connection to the builder fades. You can't prove what you stood behind. The market can't reward builders who built well.
Harmelo fixes this by making every system in every home you build signed, standardized, and transferable — from day one.
What's In The Record At Handover

The documents a buyer should already have — without having to ask.

The record consolidates the information that today lives in twelve different files, drawers, and email threads. Each entry is captured by the trade who did the work, at the moment it was completed.

// Mechanical
HVAC, hot water, ventilation
  • Make, model, serial number, install date
  • Installing technician and licence number
  • Permit numbers and inspection sign-offs
  • Manufacturer warranty registration on file
  • Commissioning report and start-up readings
  • Pre-occupancy duct cleaning entry
// Electrical
Service panel, EV charging, generation
  • Panel size, breakers, manufacturer, install date
  • Installing electrician and licence number
  • Final electrical permit and inspection
  • EV rough-in or installation, capacity, location
  • Solar or battery system if installed (capacity, inverter, permit)
  • Generator if installed (transfer switch, capacity)
// Plumbing & Water
Lines, fixtures, water heater
  • Hot water tank or tankless system: make, model, serial, install date
  • Main shut-off location and pressure reading at handover
  • Sump pump and backflow protection if applicable
  • Installing plumber and licence number
  • Plumbing permit and final inspection sign-off
  • Manufacturer warranty registrations
// Envelope & Systems
Building performance documentation
  • Insulation type and R-values by zone
  • Windows: manufacturer, U-factor, install date
  • Air-tightness or blower-door results if performed
  • Roof system: covering type, manufacturer, install date, warranty term
  • HRV / ERV: make, model, balanced airflow setting
  • Smart thermostat or controls if installed
Configured to your developments. The record reflects what you build — and what your trades sign off on.
How The Partnership Works

You set the standard. The work signs itself off.

Your trades do the registry work using access you grant them. You don't capture data, file permits, or learn a new system. The records build themselves as the homes get built.

01
You bring your trades into the registry
We send you a single link to share with the contractors working on your developments — HVAC, electrical, plumbing, solar. They sign up, upload their license, insurance, and certifications, and become verified contractors on the registry. Access is scoped to the work they do on your developments, covered as part of the partnership program. For their own service business outside your projects, contractors operate under a standard Harmelo membership.
02
The record builds as the home is built
Every install, every permit, every warranty registration, every pre-occupancy service event is captured by the trade who did the work, at the moment they did it. By substantial completion, the home has a complete and verified record of its mechanical and energy systems — signed by the technicians who installed them, with their credentials attached.
03
You hand the record to the buyer at closing
The Asset History Report becomes part of the closing package, co-branded with your developer mark alongside the Harmelo registry seal. Available on web, print, and PDF. The buyer sees the record their home arrived with, and the standard of care behind every system inside it.
04
The record stays with the home
After closing, the homeowner continues the record as systems are serviced, repaired, or replaced. The history of the home stays with the home through every owner. Your name remains on the original record as the builder who established it.
The Bigger Idea

A registry of the homes worth standing behind.

The builders who enroll their homes in the registry aren't selling a feature. They're establishing a standard at handover: every buyer takes possession with a verified record of the systems inside the home, signed by the people who installed them.

Over time, that signal compounds. A buyer comparing two homes on the same street sees which one arrived with its record. The record is structured to be referenceable across the home's life — at resale, at refinance, in deficiency disputes, by anyone with a legitimate reason to verify what was installed and when.

This is not a marketing program. It's a permanent record. The builder establishes the standard. The home carries it forward.

Your trades work under your partnership, on the projects you bring

Builder-tied contractor access covers the work your trades do on your developments as part of the partnership program. Their residential service business outside your projects operates under a standard Harmelo contractor membership — separate from the work you bring them.

Co-branded as your standard, not ours

The Asset History Report buyers receive at closing carries your developer mark alongside the Harmelo registry seal. The buyer associates the record with the builder who handed it to them — and with the standard you set on your projects.

The early builders define the standard

Founding builder partnerships shape what enrollment looks like at handover, how the co-branded record is presented to buyers, and how the registry communicates with the public. The builders who join while the registry is new are the ones the standard gets built around.

What Sophisticated Builders Ask First

The structural questions. Answered plainly.

These come up at the first call. Here's where we stand on each.

How does this interact with provincial new home warranty programs?

It doesn't replace or modify them. Tarion, Alberta New Home Warranty, BC Home Warranty, and equivalent programs operate as they always have. The Asset History Report is a supplemental record of what was installed and when, captured by the trades. It can be referenced alongside warranty documentation but does not substitute for it.

Who owns the record?

The homeowner. The record is attached to the property and travels with it through every ownership transfer. Harmelo operates the registry that stores and structures the record. The builder establishes the record at handover and is identified on it as the originating builder, but does not own the underlying data after closing.

What happens if a builder stops participating?

The records already created stay attached to the homes they were created for. Homeowners retain access to their records regardless of the builder's status. Enrollment of new developments stops; nothing about existing records changes.

Does enrollment create new disclosure obligations?

Enrollment does not alter your existing disclosure framework. The record reflects what your trades sign off on during construction — the same scope of work you already document for permits, warranty, and inspection sign-offs. Builders' counsel should review against their specific jurisdiction; we structure the record to be supplemental to existing obligations, not in place of them.

Founding Builder Partnerships

Start a conversation. Shape the standard.

If you build new homes and want to talk about what enrollment would look like in your developments, we'd like to hear from you. Founding builder partnerships are being structured one at a time. There's no menu and no contract yet — only a conversation about what serves your buyers, your trades, and your reputation. Partnership terms get worked out together.
