Benicia is one of the places where the census commits to an answer. 4,032 of the 11,454 homes counted here went up in the 1980s, a lead of 1,207 units over the 1970s that is too wide for the published margins to close, and the median build year sits at 1981. Three in five homes — 6,857 of them — were finished across those two decades, and 838 have been added since 2000. For once the paperwork is firm.

None of it reaches the ceiling. An opener is equipment rather than structure: it can be swapped without touching the door, and the door can be replaced without touching it, so the two ages come apart the first time either happens and nothing records that anywhere. Where the build year earns its keep is the parts that have never come off — hinges, rollers, cables, drums, whatever is carrying the weight — and at the median that is 45 years of opening and closing. On the machine overhead it earns nothing, so the questions are about the unit rather than the address: what is written on it, how long it has been up there, and whether the door it is pulling is still the one it was set up for.

The weather is the figure to be careful with here, for the opposite reason. The station is close enough to stand for the city, four kilometers out, but NOAA built its 1991-2020 normals from five of those thirty years — so about 36 days a year at or above 90F and about 21 inches of rain, with the “about” doing real work. What either of those does to a spring or a control board nobody has published, and we are not going to guess at it over the phone.
