HCM-117 — designated 1973-04-04
Residence
2218 South Harvard Boulevard and 2216-2222 La Salle Avenue
strong type-1 signals: high contamination probability + high alt-use on a non-residential parcel, or partial vacancy + high alt-use. hcm designation is plausibly blocking redevelopment but not all three confirmation signals are present.

Six-axis scores
- A. would-survive 5 probability the structure would survive market forces without HCM designation. low = needs protection.
- B. tourist currency 0 tourist and cultural currency — Wikipedia pageviews, walking-tour inclusion, public visitation evidence.
- C. subsidy efficiency 0 subsidy efficiency — Mills Act and federal HTC value vs preservation outcome. zero means no active subsidy.
- D. externality load 1 externality load — code complaints, CSR cases, 311 encampment/dumping/graffiti, vacancy duration.
- E. neighborhood health 3 neighborhood health — median household income, distress indicators, displacement risk.
- F. alternative-use value 6 alternative-use value — parcel acres, TOC tier, TPA eligibility, zoning capacity for higher use.
overall confidence: unknown
Condition + subsidy
all "condition" fields below are proxies derived from LADBS permit history, 311 CSR cases, and code complaints. none of these directly measures occupancy. the vacancy line shows the proxy value and the specific rule that produced it; readers should treat "active" as "construction permits filed recently," not "people live or work here."

Street view vision classification
claude vision analyzed 4 Google street view captures (n/e/s/w from the parcel coordinates) for visible distress indicators. this is an automated screening — false positives and negatives both happen, and "well_maintained" only means the visible facade is intact; internal structural condition is not assessable from street view.

- type-2 indicators (residential distress)
- vegetation overgrowth
- notes
- A large historic residence is partially visible to the west behind a metal fence with heavy vegetation overgrowth obscuring most of the structure, suggesting neglect.
Contextual signals (GIS)
these are contextual proxies — signals derived from spatial context, not direct measurements of the property. they help infer hidden variables (contamination probability, structural risk) that public open-data does not measure directly. source: cal OEHHA CalEnviroScreen 4.0 (cumulative pollution burden by census tract).

Narrative
history
hcm-117 is designated in the city of los angeles historic cultural monument registry as a single-family residence. specific construction date, original architect, and primary occupant history are not recoverable from available data; the record fields for architect prominence and assessed value are null, indicating either incomplete survey documentation or a property whose ownership and construction history have not been formally researched to the standard required for nrhp nomination. the structure is not listed on the national register of historic places. no major documented events — fires, notable ownership transfers, or adaptive reuse episodes — are on record in the fetched dataset. all historical claims beyond the bare designation facts must be treated as unverified pending archival fieldwork.
architectural significance
architectural style, period, and distinctive features cannot be characterized from the available data. the typology is recorded as single-family residential, which in the los angeles context spans craftsman bungalows, spanish colonial revival cottages, mid-century modern post-and-beam structures, and numerous other vernacular forms depending on submarket and decade of construction. no comparable extant examples can be cited without knowing the building's style, date, or designer. this represents a significant gap: without stylistic identification, the claim that hcm-117 possesses irreplaceable architectural character relative to surviving stock in its submarket cannot be substantiated or refuted.
neighborhood context
the tract surrounding hcm-117 shows a median household income of $41,908, which places it in the lower quartile of los angeles tract-level incomes and is consistent with a distressed or transitional neighborhood. population declined by 667 persons over the five-year measurement window, a meaningful contraction suggesting either housing loss, displacement pressure, or out-migration. ambient 311 load indicators (encampment, dumping, and graffiti counts) are each recorded at zero within 500 feet over 24 months, which could reflect genuine neighborhood stability or, more likely given the income profile and population decline, incomplete 311 reporting or a sparsely utilized call system in this submarket. transit proximity and toc/tpa tier are not recorded, preventing assessment of transit-oriented redevelopment pressure. | metric | value | |---|---| | census tract | 06037221500 | | median hhi | 41908 | | 5yr δ population | -667 | | 311 within 500ft (24mo) | 0 | | encampment 311 calls | 0 | | ladbs code complaints (24mo) | — | | last permit year | — |

classification reasoning
axis a (survival without protection) scores 5 at medium confidence. the score reflects that an unidentified single-family residence in a low-income, contracting-population tract faces genuine market pressure — the neighborhood does not generate the premium that organically protects architecturally notable stock — but without architect prominence, nrhp status, or evidence of recent owner investment, the positive case for organic survival is equally weak. the score is a midpoint assignment driven by uncertainty rather than affirmative evidence in either direction. axis b (tourist/cultural currency) scores 0; there are no google reviews, no wikipedia pageview data, no walking tour inclusion, and no nps designation. this structure draws no documented outside visitation and has zero measured cultural currency beyond its local designation. axes c and d (subsidy efficiency and externality load) both score 0. c is scored 0 because there is no mills act contract, no federal htc, and no vacancy or code complaint data against which to measure subsidy performance — the score is a data void, not an affirmative finding of efficiency or inefficiency. d scores 0 on medium confidence: the three measured 311 proxies (encampments, dumping, graffiti) are all zero, suggesting the parcel is not currently generating negative spillover, though the absence of code complaint data leaves this partially unconfirmed. axis e (neighborhood health) scores 3 at high confidence: median hhi of $41,908 and a five-year population loss of 667 persons are objective indicators of a distressed or declining district. axis f (alternative use value) scores 0 due to null parcel acreage, unknown zoning capacity, and no tpa/toc tier — redevelopment upside cannot be quantified. the reassess flag is applied because the overall confidence rating is 'unknown': three of six axes have unknown confidence, the candidate flag conditions are partially met on e (score 3, below the ≤5 threshold) and partially on a (score 5, above the ≤4 maximum for candidate), but c and d do not meet the minimum thresholds (both score 0 rather than ≥6) and f is unscored. the data state is too incomplete to support candidate designation, but also too incomplete to support maintain or do_not_touch.
