Property Screening Packet
Source-backed facts, knowns, unknowns, and verify items before deeper diligence spend.
1240 N Vista St, Los Angeles, CA 90046
Illustrative sample — based on the type of source-backed findings GroundRules provides for a supported City of Los Angeles property. Not a real customer.
Assessor says 6,503 sq ft. GIS parcel says 6,211 sq ft.
Verify parcel dimensions before you make an offer, quote a project, or rely on deeper diligence assumptions.
Source-backed signal only. GroundRules surfaces the conflict and marks it for verification. This is not a claim about which source is final.
What GroundRules checked and found
GroundRules checked the submitted address against US Census Bureau — Geographies API (Public AR Current benchmark), LA County Office of the Assessor — Parcel Map Service, and other cited public-source references. The screening identified that this property appears to fall under City of Los Angeles and surfaced a zoning signal of [Q]RD1.5-1-HPOZ.
This report remains preliminary because GroundRules still expects manual verification before parcel-specific conclusions are relied on or delivered as final advice.
Customers can still use this screening result before spending money because it shows what GroundRules safely found, what it refused to guess, and where deeper due diligence should focus before design, underwriting, purchase, listing, or contractor conversations move forward.
Fire / hazard screening result: Very High Fire Hazard Severity Zone (VHFHSZ): No — parcel not within a mapped VHFHSZ (confirm with city). That is a useful signal, but it should still be confirmed against the cited public source before anyone relies on it for go/no-go decisions.
A wrong property assumption can cost thousands. This packet separates what public records support from what still needs verification — so design, underwriting, listing, bidding, or contractor conversations start from confirmed facts, not guesses.
Other screening signals
What GroundRules refused to guess
- Parcel-specific APN, lot size, building area, permit history, or parcel match unless manually verified
- ADU approval likelihood, entitlement path, or permit-readiness
- Zoning, setback, height, or use conclusions that depend on an unverified parcel match
- Final buildability, investment feasibility, or code compliance determinations
What still needs verification
- Parcel identity and APN before relying on parcel-specific facts
- Lot size and parcel dimensions
- Existing building area and building details
- Permit history, open permits, and violations
- ADU-specific zoning and development standards
- Overlay or hazard constraints that could affect scope, cost, or review path
Recommended next steps
- Confirm the parcel record and APN before relying on parcel-specific facts.
- Verify ADU-specific zoning and development standards with the cited jurisdiction sources before design or pricing decisions move forward.
- Check permit history, overlays, and hazard triggers before anyone treats the opportunity as permit-ready.
- Use this report to decide whether a deeper manual review is warranted before more money is spent.

This is a preliminary screening result, not a permit approval, buildability determination, or legal / architectural / engineering / survey opinion. Missing or parcel-specific facts require manual verification before design, acquisition, pricing, listing, or permitting decisions rely on this property.
