WalkthroughKit — walkthroughkit.com — Built for My World: Interim Housing in Los Angeles.

I built WalkthroughKit for the world I’ve lived in for over a year: interim housing in Los Angeles. I’ve watched housing navigators and case managers try to move my neighbors into permanent housing, Form 1083 on a clipboard, walking a unit with a phone, no signal in the basement, trying to prove 11 requirements where one missed photo of a faucet or detector means a rejected packet and days of waiting for someone who has already waited months.

I know that wait. I live it.

WalkthroughKit has two parts, both built for that world:

A. Free Building Pre-Screen — walkthroughkit.com/
Built so anyone can check a building before a navigator wastes a trip. I enter any LA address; Census Geocoder resolves it, then nine LA-specific datasets run in parallel: LADBS open cases, LAHD violations, FEMA flood, HUD lead/assisted housing, EPA TRI, OpenFEMA disasters, and — with owner name from the LA County Assessor — SAM.gov federal exclusions + entity identity. Address is looked up, never saved. Every result links to its source.

B. Guided Walkthrough Companion — walkthroughkit.com/app
Guided Capture: A pseudonym + funding intake (HUD → HQS notice, CoC/ESG → Form 1083), then 4 room clips (60MB/30s) with real prompts from the actual inspection: faucet, fan, lock, detector. Local-first, works where signal doesn’t.
Evidence-Grounded Draft: On explicit tap, Meta SAM 3.1 locates fixtures per clip, producing timestamped stills. Muse Spark maps them to the 11 Form 1083 elements — but AI is always an unreviewed draft; only the evaluator’s Accept/Deficient/Needs Check creates the determination. Fire Safety 11a/11b decided separately.
Signed Export: Local client file, landlord fix-list, and flattened official LAHSA FY22-23 Form 1083 with evidence pages + JSON for manual HMIS handling. No direct submission. Staged mock-unit data only; every export labeled Not an HMIS submission.

It’s a PWA, mobile-first, offline-tolerant — built for the world I live in, by someone who lives in it.
