The census counts 2,216 of American Canyon's 6,055 housing units finished between 2000 and 2009, and that period clears every other row on the table by more than the margin on the difference — 45.6% of the stock has gone up since 2000, at a median build year of 1996. The table stops sorting there, though: 851 units from 1980 to 1989, 760 from 1990 to 1999 and 655 from 1970 to 1979 fall inside a spread of 196 units, and the margin on that difference on its own is 251 — three periods with no second place among them. Set against the two federal opener dates, the census cannot place this housing cleanly on either side of either one: the bucket that would decide it runs from 1990 to 1999, and both dates fall inside it. An operator manufactured on or after January 1, 1991 already had to reverse within two seconds of meeting a two-inch test object; from January 1, 1993 it also had to carry a second, separate line of protection. So the live question in a garage here is not whether that protection is there but what form it took, and the rule permits four: a photoelectric sensor across the opening, an edge sensor on the door's bottom edge, an inherent door sensor independent of the primary system, or another device giving equivalent protection. A force-activated one has to trip at 15 pounds or less closing and 25 or less opening. Those are not the same call-out, or even the same part of the garage — a beam and its wiring sit at floor level, an inherent sensor is a limit and a board inside the head unit — so a door that starts down and comes back gets traced to whichever is fitted before anything is adjusted. Both dates describe the machine rather than the house, and on the 27.8% of this stock built before 1980 the head unit can be of any vintage at all.

The other rule that lands on the door here is a fire one, and it reaches the newest end of the stock. CAL FIRE's mapping covers the city end to end, but in three classes rather than one — High, Moderate and NonWildland, the last of which is mapped low-hazard ground. California's wildland-urban interface chapter is where a garage door turns up in a fire code at all: the model code most of the country builds to lets vehicle access doors out of its exterior-door requirements, and California's does not. What it asks about is the outside face of the door — a noncombustible or ignition-resistant surface, solid core wood, a cladding that passes the tests it names, or a 20-minute fire-resistance rating tested to NFPA 252 — and nothing about the counterbalance, the track or the opener behind it. It governs new buildings, so here it is the 512 homes finished between 2010 and 2019 and the 33 since 2020 that went up while it was in force, and nothing in it asks for a change to a door already hanging. Nor does the hazard map settle who it covers: a WUI Fire Area is identified by whoever enforces the code at that address, which makes it a question to answer before a replacement door is ordered.
