San Francisco / Belvedere
Belvedere has 2,345 residents (give or take 329) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0605164, checked 2026-10-19), about 4,518 people per square mile.
Belvedere is about 32 miles from the Census center point for San Francisco in a straight line and covers 0.519 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).
4,518 people per square mile puts Belvedere in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 886 occupied homes in Belvedere, 78% heat with natural gas, 0% with heating oil, 16% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0605164, checked 2026-10-19).
Gas heats 78% of Belvedere against electricity at 16%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Belvedere has about the Marin County oil share of 0% and 10 points less electric heat than the county's 26% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US06041, checked 2026-10-19).
Belvedere has 1,081 housing units, 17% built before 1940 and 82% before 1980, with 5% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0605164, checked 2026-10-19).
Belvedere has 4 points more pre-1940 homes than Marin County as a whole (13%) and 3 points fewer homes built after 2000 than the county's 8% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US06041, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Belvedere home was built in 1959 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0605164, checked 2026-10-19) and the median home has 7.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0605164, checked 2026-10-19).
86% of Belvedere homes are single-family detached, 6% are in two- to four-unit buildings and 3% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0605164, checked 2026-10-19).
With 86% detached houses and 6% in small multi-family buildings, a Belvedere quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 32% of Belvedere homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0605164, checked 2026-10-19), the landlord signs the quote in many of them.
Belvedere has 23 points more detached houses than Marin County overall (63%) and 16 points fewer five-plus-unit buildings than the county's 19% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US06041, checked 2026-10-19).
82% of Belvedere homes were built before 1980 and only 5% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0605164, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
No electric utility is on file for Belvedere on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
LADWP Consumer Rebate Program heat pump HVAC, run by LADWP, is a live program for California addresses and publishes its terms without one headline figure (registry row 24 verified 2026-10-14, https://www.ladwp.com/residential-services/assistance-programs/consumer-rebate-program, checked 2026-10-16); confirm eligibility for the Belvedere address before counting it. With 16% of Belvedere homes already on electric heat and 79% 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 Belvedere is $250,001 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0605164, 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: 27F.

That 27F figure is the Marin County cold-day number a Belvedere heat pump is sized against, so ask the installer to show the system's heating output at 27F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 78% of Belvedere on gas and 16% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Belvedere home has 7.3 rooms and was built around 1959, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
