Hartford St North Block
The 0-100 block of Hartford St is almost solely the work of “master builder” Fernando Nelson, who famously built thousands of homes in SF over the course of his half-century career, and acted as one-man savings and loan to many of his customers.
Hartford St North is an example of blue-collar Victorians in the “streetcar suburbs” growing in San Francisco at the turn of the century. These houses are the transition period between the vernacular, unprofessional infill housing in chaotically inclusive urban spaces, and the commissioned exclusive automobile-reliant suburbs of the 1920s and later. As non-status buildings - specifically meant to be owned by blue-collar workers and not just rented to them - the buildings on Hartford St are a rare survival, and illustrate the incredible quality of life available to migrants willing to make the trip West.
Block history in a nutshell
Hartford St North was originally part of Rancho San Miguel, then blocks 148/149 of Horner’s Addition, then listed as “Mission block 114”, and only much later (when the City consolidated the previous different survey block numbers) became “Block 3582” as it’s known today.
The northwest corner of MB 114 was purchased before 1863, and so excluded from the Eureka Homestead Association, but we don’t know when or by whom. Because of the protracted probate battle (and intra-family strife) in the J.P. Treadwell estate, the majority of this block was the last open space in the area waiting to be developed and the road cut.
The middle and southerly blocks were parceled out in the Eureka Homestead Association in the mid to late 1860s. Because of this, Hartford St Central and South were weirdly numbered, consecutively upwards as you went south (uphill) on the west side, then crossing the street and the numbers continuing to increment as you went north (downhill). It looks as if the numbering changed at least once between 1865 and 1900.
Originally MB 114 block was platted to include an extension of Ford St, which runs between Sanchez and Noe, parallel to 17th/18th, one block east. Some time between 1898 and 1901 block 114 got a north-south road to extend Hartford instead.
The two preexisting blocks of Hartford were renumbered in 1901 to fit the SF municipal scheme, which is to say the house numbers increase by 100 each block you get further away from Market, and odd numbers are on one side, even on the other.
This third and final North block brought Hartford closer to Market St, so the blocks were renumbered again to unify the number scheme. Hartford North became numbers 0-99, Hartford Central became 100-199, and Hartford South became 200-299.
Noé and Rancho San Miguel
The first owner of the land was Jose de Jesús Noé, who was granted a patent by the Mexican Government after the dissolution of the Missions. For various reasons, he sold up his massive Rancho San Miguel and lived out the rest of his life on Elizabeth St near the Old San Jose road.
Horner, Horner’s Addition, and the Panic
John Miers Horner arrived with a group of Mormon settlers (including Sam Brannan) on the ship The Brooklyn, in 1846, when California was still part of Mexico. He began farming in Mission San Jose in 1847, made immense profits and invested them into more land.He founded Union City, and lived along its north edge - then known as Centerville.
In mid 1853 Horner bought part of Rancho San Miguel from Noé. This was after California was admitted to the Union, and after Noé’s land claims was settled in his favor. Horner, for lack of a better name, called it “Horner’s Addition”, as it was fully in the “Outside lands” outside the City Charter.
“In San Francisco county, we paid two hundred and eighty-five thousand dollars for five thousand two hundred and fifty acres of land adjoining the city of San Francisco, and expended nearly eight thousand dollars upon it in surveys, fences and other improvements. One thousand and fifty acres of these lands we surveyed and staked into streets, blocks, and lots, extending the streets of San Francisco over it. It is now, and has been for over thirty years, a part of that flourishing city.” —John M. Horner
He says a large number of squatters devalued his property:
[…] the closer these squatters could get to San Francisco, the better they liked it; and if the land was surveyed and staked into streets, blocks, and lots, the better, as then they could and did sell lots cheap to innocent parties.
Basically, with the owners living near Union City, there was little or nothing that could be done to prevent some random guy from setting up shop and selling the lots to unwary newcomers.
There is an interesting account of the early days of the development of Horner’s Addition in the writings of Caroline Barnes Crosby who lived with the Horner’s during 1854 and 1855. One the accounts read:
“Sun 29th [January 1854] A beautiful pleasant morning. . .Alma Frances and myself took a walk over the hills, to take a view of br[other] Horner’s new purchase, and to get a peep at the Spanish house where we expect to reside, after a few weeks. We admired the scenery very much; and think in short time it will be a great place. We walked from bluff to bluff until we arrived at the top of a high one nearly in front of the dobie [NB: adobe] house where the spaniard resides of whom Mr H bought the land [NB: Noé]. We then sat down to admire the prospect. And we came to the conclusion that altho it was not quite retired, yet it was a most beautiful and romantic place. . .” [pages 239-240]

Horner sold off a number of lots before his bankruptcy sale on April 25 1855, but not with great success. The Panic of 1857 began around 1853, and completely destroyed him financially. He was forced to sell almost all of his lands and worldly goods, including his San Francisco property. After struggling to regain his farmholds, he eventually relocated to Maui, Hawaii (then the Sandwich Islands, and about a hundred years away from being illegally seized and annexed by the business interests of the United States) to run the sugar plantations for Claus Spreckles.
Pioche and Robinson, Meeteer, Treadwell, and the Eureka Homestead Association
More research is required here as I have found index entries for some deed transfers, but not the deeds themselves.
Block 114 was part of J M Horner’s purchase and Horner’s Addition, and labeled 147 and 148. However, it wasn’t part of the Eureka Homestead Association purchase made in April 1863, and we know Marshall Meeteer was listed as living at the corner of 17th and Castro in 1862. We also know that the Market/17th/Castro corner had a saloon on it very early - more research required there.
The Eureka Homestead land is so platted:

Commencing at the intersection of the northerly boundary of the San Miguel Rancho with the westerly line of Castro street; running thence southerly along the westerly line of Castro street to the southerly line of Falcon street; thence easterly along the southerly line of Falcon street to the westerly line of Noe street; thence southerly along the westerly line of Noe street to the northerly line of Napa street; thence westerly along the northerly line of Napa street to the easterly line of Douglass street; thence northerly along the easterly line of Douglass street to a point 200 feet north of the northerly line of Corbett street; thence at a right angle easterly and parallel with Corbett street 550 feet, more or less, to the northerly boundary of the San Miguel Rancho; and thence southeasterly on said northerly line of the San Miguel Rancho to the place of beginning,” (excluding therefrom Noe, Castro, Diamond and Douglass streets, running north and south; also, Corbett, Falcon, Eagle and Napa streets, running east and west, for public highways); the tract of land above described being equal to about 17 1/2 blocks of 250 by 550 feet each. NB: 17th St was known as Corbett, and 18th was called Falcon at the time of this writing.
The platting starts at the edge of block 114 and works its way back, continuing to exclude it. This means block 114 was definitely sold either by Pioche and Robinson, or Horner before 13th of April, 1863.

We DO know that Marshall M Meeteer, and LL Treadwell were the two owners of that corner of MB 114 for a good long while. Meeteer sold off chunks of his original homestead as normal-sized city lots, then sold off the rest of the property to Andrew Spaulding.
We don’t know how LL Treadwell came by the rest of the block, but that whole family was… dramatic.

Treadwell to Treadwell
In 1875, LL Treadwell, JP’s brother, sold him the “irregular lot” that is the portion shown. We have to go further back to try to find the purchases of the corner pieces that were already bought and built on by that time. LL died in Feb of 1876.

Oh dear there are a lot of Treadwell listings in 1900. Though more than half appear to be just cases where A. B. Treadwell, attorney, is involved.

It looks like Thalia Treadwell held the land for less than a fortnight after probate distribution
This deed was recorded 6 June 1900, but was… backdated…? to 31 March 1900, before the probate distribution. Hmmmm. She’a also selling this with John T Harmes, who one assumes is her spouse?
Interestingly, she sells this parcel separately.

Andrew Christensen swoops in
(NB: all of this could probably be resolved by looking at the block book, I just haven’t had time to do so.)
It looks like Andrew Christensen was the first person to buy a lot on the newly-subdivided Mission 114 block per this SFCall notice from 9th June 1900. If that’s the first house, then he must’ve started building nearly immediately since our “first building on Hartford St” photo is dated 28 June 1900.

The San Francisco Call for 9th June, 1900
John T. Harmes and Thalia Treadwell to Andrew Christensen, lot on E line of Hartford street, 137;4 S of Seventeenth, S 26:2 by E 125; $10.
It looks like his brother bought the adjacent lot a month later.
Thalia Treadwell (single) to Jens Chr Christensen, lot on E line of Hartford street, 163:6 S of Seventeenth, S26:2 by E 123; $10.

The San Francisco Call for 8th July, 1900
The first builder contract I found shows Andrew Christensen commissioning a building on the lot that became 27/29/31 Hartford St, through Cotter and Jones (contractors), and W. McMillen (architect), which is interesting because in the course of my researches through Edward’s Abstracts, it sounds like Andrew Christensen was himself a contractor. Huh.
It’s signed on 18th June, recorded 19th June, and reported the next day in the Call:

The San Francisco Call for 20th June, 1900
It’s also listed in Organized Labor, Volume 1, Number 21, 23 June 1900

- [nb: 73rd contract in June] Hartford street, east line, 137.4 feet south of Seventeenth —Carpentry, plumbing, plastering, brick work, etc., for a two-story frame building, flats. Owner, Andrew Christensen; architect, W. McMillen; contractors, Cotter & Jones. Cost, $3,734.
Interestingly, although Christensen’s contract lists a two-story building, the first one to go in was the three-story building that we see already mostly framed out by June 28th. This lot, reading out the surveyor numbers, corresponds to parcel 3582/035, or 27/29/31 Hartford. Huh.
The construction was accepted 30 August 1900:

The building on Andrew’s brother’s lot next door didn’t go up until after 1902, based on the DS Wulzen photo from the old Corbett road. Knowing that it’s not in the same year, I haven’t had time to go search for it.
And indeed, it looks like Jens C Christensen and his wife Thorea sold their lot to Andrew in around 28 March 1901.
San Francisco Call, Volume 87, Number 118, 28 March 1901
Regardless of what happened, and perhaps puzzlingly, both the three-story flats at 27/29/31, and the two-story flats at 33/35 have the same layouts, and all of the same trimmings and mouldings as other Nelsons on the block. Did Christensen fire his contractor and hire Nelson at a savings? Or were there just limited resources for interior decoration in 1900/1901?
Nelson’s purchases
At any rate, Fernando Nelson bought a Hartford chunk of the Treadwell block in November 1900, and it was a big enough deal to be in the newspaper two days running.
24th October, recorded 2nd Nov 1900:


San Francisco Call, Volume 87, Number 158, 5 November 1900
And he wasted no time setting up to build.

[Building contracts for November] Hartford street, east line, between Noe and Castro - Eleven frame cottages. Owner, architecte and contractor F. Nelson. Cost, $1600
Organized Labor, Volume 1, Number 41, 10 November 1900
He later bought up the other side of the block from 18th and Noe north:

San Francisco Call, Volume 87, Number 24, 24 December 1900
He gets the lot at the NW corner of 18th and Noe.

San Francisco Call, Volume 87, Number 154, 3 May 1901

Hartford, east line, 100 N 18th — Erect 3-story and basement. 0., F. Nelson. Cost. $4,900. Organized Labor, Volume 2, Number 44, 30 November 1901
So here’s our San Francisco Block Book for October 1901.

The 18th st flats
Nelson then (grudgingly?) buys the lot for the apartment building at the SE corner of 17th and Hartford, which becomes one of the sets of flats.

On May 1st, 1902, D.H. Wulzen scales Corbett and takes this amazing photo, from which we can see the backs of the West side houses, and the tippy tops of the East siders, along with Meeter House, the windmill and water tank, and the Spaulding’s paddock.

A competing block book publisher for some reason shows up here.

But it also includes a map of established grades O_O which shows us that the “extra” numbers at the intersections are the grade height. Because the Misison block and Horner’s Addition are indexed together, we don’t get contour lines like some other indexes.
