GMP territory. The $2,000 per condenser income-eligible heat pump bonus applies (households at or below 80% AMI). Stack with EVT $2,200 ducted, $400 fuel-switching, $500 panel upgrade rebate.
Basement finishing pairs well with weatherization scope. EVT's 75% rebate (standard tier) covers rim joist sealing and basement wall insulation when included in a Home Performance with ENERGY STAR project. Income-eligible homeowners get 90%.
Trap: the contractor whose bid quotes a rebate stack from a different utility territory. Ask them to break out each rebate by name and confirm in writing which ones apply to South Burlington (Green Mountain Power (GMP)). Bids that show "$X off after rebates" without naming the rebates are the ones that lose money on the actual paperwork.
Basement finishing is a winter-friendly project. Vermont contractors prefer winter scheduling — the dry interior environment works well for drywall and finish work, and crews aren't pulled away by summer exterior demand.
Vermont egress requirements apply: any finished basement room used as a bedroom needs a code-compliant egress window. Plumbing additions trigger fixture permits. Electrical work requires a licensed Vermont electrician. Confirm scope and licensing in writing before deposit.
Vermont-specific: South Burlington has stronger contractor density than rural Vermont, so expect 4-6 serious bids in a typical project. Use the variance to identify the bid that's missing scope (cheapest, often) and the bid that's overpriced for South Burlington (most expensive, often).
