Records can establish a useful baseline
Depending on the jurisdiction and source, public records may help identify the parcel, reviewing agency, assessor characteristics, base planning designations, and indexed permit documents.
A useful research summary cites the source and retrieval date instead of blending several websites into one unsupported conclusion.
- Parcel and jurisdiction identification
- Recorded building and lot characteristics
- Planning and mapping designations
- Publicly indexed building documents
- Missing or conflicting information
Records do not inspect the property
A database cannot confirm the current dimensions, physical condition, construction quality, utility capacity, or every change made over the life of a building. A permit index also does not automatically prove that everything visible today was approved or built exactly as documented.
A label is not the same as an interpretation
Finding a zoning label or permit entry is different from understanding how it affects a proposed ADU. Interpretation may require complete documents, field information, current jurisdiction procedures, and licensed consultants.
That is why a records-only product should stop before declaring feasibility or predicting approval.
Good research makes uncertainty visible
The most trustworthy report is not the one that sounds certain about everything. It is the one that distinguishes official facts, client-provided information, observations, professional inference, unknowns, and items requiring verification.
Use public records to organize the starting evidence—not to replace measurements, professional judgment, or formal city review.
