WattShed Blend
Who gets what, when the building and the bills belong to different people.
Every split rule here is one you enter. WattShed ships no policy defaults of its own, because split-incentive rules are program and jurisdiction specific: set the owner's share of the eligible cost, any cap on it, an optional tenant-protection holdback, and an optional per-unit tenant benefit, then check one project against exactly those rules.
This is arithmetic over the split rules you enter, not landlord-tenant legal guidance, and protection certification is your program's own process, not something this page performs. Everything computes in this browser; nothing you enter is stored.
The program's split rules
Owner share
Nothing is prefilled. Set the share of eligible cost this program pays the owner, and an optional dollar cap on that share.
The program's split rules
Tenant protections and benefit
Both optional. A holdback withholds part of the owner's share; a per-unit benefit pays occupied units directly.
The project
This project's numbers
The project's total eligible cost, how many units it affects, and how many of those units are occupied.
Result
Set the program's split rules on the left, starting with the owner share percent, to see a result.
Arithmetic over the split rules you set above. Not landlord-tenant legal guidance, and it certifies nothing: protection certification is your program's own process.

Why splits exist
The building and the bills don't always belong to the same person.
The owner pays, tenants hold the bills
In most rental buildings, the owner decides whether to fund an efficiency upgrade, but the tenant is the one paying the utility bill it changes. The owner has little reason to spend on savings they will never see, and the tenant has no say in a capital decision that is entirely the owner's to make. A split-incentive program exists to close that gap.
Holdbacks and protections
A holdback keeps back part of what a program would otherwise pay the owner until the tenant protections that program requires, no rent increase tied to the upgrade, existing leases honored, whatever the program specifies, are certified. That certification is your program's own process; this tool only computes the dollar amount held and the dollar amount released.
What an unfunded remainder means
When an owner's share is capped, the program's dollars can fall short of the project's full eligible cost. The gap between what the program actually pays out and what the project costs is the unfunded remainder: cost nobody in the split rules you entered is on the hook for.
A clean result here does not confirm a project qualifies for any program, and it never certifies that a tenant protection has been met. It confirms the split rules you entered add up the way you said they should.
