Portland / Cottage Grove
Cottage Grove has 10,698 residents (give or take 26) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4115950, checked 2026-10-19), about 2,757 people per square mile.
Cottage Grove is about 122 miles from the Census center point for Portland in a straight line and covers 3.881 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
Of the 4,225 occupied homes in Cottage Grove, 32% heat with natural gas, 0% with heating oil, 63% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4115950, checked 2026-10-19).
Electricity already heats 63% of Cottage Grove homes, ahead of gas at 32%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Cottage Grove has about the Lane County oil share of 0% and 12 points less electric heat than the county's 75% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US41039, checked 2026-10-19).
Cottage Grove has 4,479 housing units, 13% built before 1940 and 55% before 1980, with 20% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4115950, checked 2026-10-19).
Cottage Grove has 6 points more pre-1940 homes than Lane County as a whole (7%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US41039, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Cottage Grove home was built in 1977 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4115950, checked 2026-10-19) and the median home has 5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4115950, checked 2026-10-19).
66% of Cottage Grove homes are single-family detached, 10% are in two- to four-unit buildings and 13% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4115950, checked 2026-10-19).
41% of Cottage Grove homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4115950, checked 2026-10-19), so beside the 66% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Cottage Grove has 5 points more detached houses than Lane County overall (61%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US41039, checked 2026-10-19).
41% of Cottage Grove homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4115950, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
No electric utility is on file for Cottage Grove on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Energy Trust of Oregon heat pump incentives, run by Energy Trust of Oregon, is a live program for Oregon addresses and covers qualifying equipment at $1,000 per system (registry row 15 verified 2026-10-15, https://www.energytrust.org/incentives/residential-cooling-solutions/, checked 2026-10-16); confirm eligibility for the Cottage Grove address before counting it. With 63% of Cottage Grove homes already on electric heat and 32% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Cottage Grove is $80,875 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4115950, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.
Heating design temperature: 26F.

That 26F figure is the Lane County cold-day number a Cottage Grove heat pump is sized against, so ask the installer to show the system's heating output at 26F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Cottage Grove home has 5 rooms and was built around 1977, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
