The Problem: Hallucinations in Pure LLMs
Large language models like ChatGPT, Gemini, or Claude are trained on billions of tokens of data. When asked something that doesn't appear exactly in their training, **they invent convincing answers that sound correct but are completely false**. This is called a hallucination.
Real example: Ask ChatGPT "What is article 17.5 of the LPH?" and it could invent a majority or protection that doesn't exist. For a property manager, this is a legal disaster.

Hallucination: How It Happens
The Pure LLM Flow
Input: "What is article 17.3 of the LPH?"
Process: The model searches its trained parameters for patterns similar to "articles + LPH"
Output: Generates a sequence of words that "sounds good" but without verifying against a real document
Risk: Provides the manager with false information with complete confidence
The Solution: RAG Enforces Verification
RAG completely changes the flow:
- Fact Search: First, search for article 17.3 in your legislation database
- Literal Extraction: Extract the exact text from the original PDF or document
- Guided Generation: The LLM only generates responses based on that document, without inventing
- Mandatory Citation: Always includes the source: "Article 17.3, Page 45, Paragraph 2"
Real Example: LPH in Igera
Question: "How many owners are needed to approve an elevator?"
RAG responds: "According to Article 17.2 of the Horizontal Property Act, a simple majority of owners present at the meeting is required. Source: Official State Gazette, LPH 1960, page 3."
Every word you see comes from the actual document. Zero hallucinations, zero risk.
Why This Matters in Property Management
- One incorrect AI-based decision → immediate legal challenge
- Unhappy owners → bad reputation for the manager
- Legal fines → unexpected economic cost
- With RAG → every decision is backed by current law
