The Salton Sea State Recreation Area headquarters has the address 100225 State Park Rd, East Imperial CA 92254. This is part of the perfectly regular Riverside County numbering system, 1000 to the mile. ---

[QUOTE=RangerJeff] I wonder what the SMALLEST address is, i.e., what the smallest fraction of an address there is. I’ve seen 1/4ths, but not smaller. [/QUOTE] In terms of the units, 1/26ths, as in 123A Any Street and 123B Any Street. The highest alphabetic fraction I can recall seeing (and living in) is C, but that doesn’t mean there’s not a large house somewhere that got diced up into flats (depressingly common in San Francisco) going up to E, F or beyond. ---

> [@Spectre\_of\_Pithecanthropus](#): > > From what I’ve read I think wherever it was The Doors used to rehearse in Venice, before they made it, might be even higher. For those that don’t know, house numbers in Venice are weird. Every address in a district has a unique number, adjacent buildings may or may not have consecutive numbers. I’m not sure how high the numbers go, certainly into thousands, maybe tens of thousands. I’m not sure if that’s what SOP meant, it isn’t clear, but relevant anyway. ---

The highest house number in Venice is [6828 Castello](https://commons.wikimedia.org/wiki/File:Venezia_6828_Castello_highest_housenumber_20090228.jpg). Castello is one of the six districts of Venice, and the house numbering is based on the district - each house gets a unique number in that district which just goes up, as you describe, from 1 consecutively. It’s a very confusing system to the visitor, and it is more ancient than the modern form of street-based house numbering; it’s not overly ancient, though, having been introduced in Napoleonic times. ---

> [@suranyi](#): > > That’s not cheating – that’s standard American (and Canadian) house numbering structure. > > For one thing, it allows room for new construction between already existing buildings. Well, from a European perspective it may be somewhat cheating, since we are accustomed to much lower house numbers - a figure in the thousands or even high hundreds would be considered extraordinarily high and indicate that the address is “far out”, since the numbering typically starts with 1 in the city centre and then goes up consecutively as you move outward (with the odd numbers on one side and the even ones on the other). On top of that, it is my impression that named streets are typically much shorter in European cities because street names tend to change with a major intersection - we don’t have those streets that go on for miles and miles, first through urban and then through rural areas, without ever changing name. Of course, sometimes addresses are skipped, when previously separate lots are merged, giving you addresses like 34-38 Soandso Street (where somebody built a building on what used to be house numbers 34, 36, and 38). We do not have the North American (and Latin American?) custom of going up to the next 100 each block, though; it’s just a consecutive sequence of numbers. ---

At the end of my street, if there was a house there, it would be number 100. But’s a 50 townhouse complex, the address of the first unit is 1/100. I expect this is commonplace. ---

Castello is one of the six districts of Venice… That’s surprising. 6 districts, each with less than 7000 buildings, so under 40,000 buildings in the city. Somehow I’d have thought it was a higher number than that. ---

> [@ralph124c](#): > > What’s the highest address on Colorado Blvd. (Los Angeles)? It runs from Pasadena into Santa Monica-it is pretty long. This is a very poor choice. It changes names and goes thru various jurisdictions which causes a reset of numbers. Starting west at 0 at Fair Oaks, it is W Colorado., then just plain Colorado Blvd, then Colorado St. Around Carr Park it goes from increasing towards 3000 to re-starting at 1700 and dropping. At S Brand it reaches 0 and increases again as it becomes W Colorado St (or Blvd in some places?). It ends at San Fernando Rd around 700. Starting over from Fair Oaks going east, E Colorado Blvd gets up to around 4000 where it becomes W Colorado Blvd again around Michillinda. Where the numbers are like 1200 and falling. Later, rinse, repeat. (It quickly changes back and forth between E and W some more before ending at Recreation Park, not reaching 700 at that end.) There is a Colorado Ave. in Santa Monica but is it not very long and has nothing to do with Colorado Blvd. ---

> [@ralph124c](#): > > What’s the highest address on Colorado Blvd. (Los Angeles)? It runs from Pasadena into Santa Monica-it is pretty long. Length isn’t the only determining factor. If a road passes thru multiple municipalities, as **ftg** illustrates, the numbering may restart from zero. We need to find a very long road that is entirely within a single, large city. And not an East/West or North/South, either, which will split the numbering and reduce the max. ---

> [@Really\_Not\_All\_That\_Bright](#): > > Surely American numbers are cheating, since they’re not sequential. I wouldn’t call it cheating. American numbering systems are designed to accomodate future development, so the system doesn’t get out of whack if you build a new house between two existing ones. I remember reading about a major Asian city (Tokyo? Hong Kong?) where street addresses are based on how old the building is, and the result is a nightmarish system where address numbers jump around pretty much randomly, and finding an unfamiliar address can be a major pain. ---

> [@Diceman](#): > > American numbering systems are designed to accomodate future development, so the system doesn’t get out of whack if you build a new house between two existing ones. The European system can accomodate that eventuality pretty well. The traditional way is to use fractions - a house built between 56 and 58 would be 56½; another one built between 56 and 56½ would be 56¼, one between 56½ and 58 would be 56¾, and so on. More recently, it has become common to use letters - 56a sneaks in between 56 and 58. It may be a bit cumbersome, but it does the job just fine. ---

Yeah, but until all those numbers in between get filled up, it’s pretty meaningless. I can see leaving out numbers for parcels that have no buildings yet, but jumping numbers between two developed lots is silly. I live in a normal detached suburban house which has about eight feet of clearance between it and the next house. 1609 is us, and 1610 is the house across the road. That’s fine - but the next-door neighbor is 1615. Why? Nobody is ever going to be able to fit a 1611 and 1613 in! Anyway, a much more pertinent question is why the numbers don’t start from the bottom. The first house on my street is 1501, not “1”. It’s not like there is a forest at the end allowing further development. ---

Because the numbers start from a point of origin downtown, which is the “American” system used predominantly west of the Alleghenies; and not from the beginning of the street, which is the “European” system used in the Old World and early America. More explanation in the other thread. As for speculation about this street or that being the longest, do have a look at post #51 first. And remember that when we’re talking about an American point-of-origin system, the biggest house number need not be on a long street. It can be on a 100-foot-long cul-de-sac—provided that’s a long distance from the point of origin used for the jurisdiction.
