Renting or living in a condo? Here's what actually applies to you
Most of the numbers above assume you own a single-family or multi-family home and control the whole building. That's not every Lowell homeowner — a former mill city with a lot of multi-family housing. Here's what changes:
If you rent
You can't claim the heat pump, insulation, or solar rebates — those go to whoever owns the property. The free Mass Save home energy assessment is still worth requesting through your landlord, since it often comes with a free smart thermostat and other no-cost measures. If you want the bigger upgrades done, the ask has to go to your landlord — point them to this page.
If you own a condo unit
In-unit upgrades you control yourself — a heat pump water heater, in-suite windows, an in-unit heat pump — can qualify for the Mass Save rebates above, usually with your condo association's approval for anything touching shared walls or exterior systems. Get that approval in writing before your contractor applies.
If it's a whole-building retrofit
Heat pumps, insulation, and solar for the whole building go through the condo association (or, for multi-family rentals, the property owner) as a group decision, and Mass Save's multi-family program handles the paperwork rather than the single-unit process on this page. The HEAT Loan and Mass Save's free assessment are both still available — the owner or property manager coordinates the application, not individual tenants.
