Documents to Collect Before Buying Land
Use documents to collect before buying land to spot access, title, parcel-status, and due-diligence issues before buying land.
Method: Official-source research, plain-English synthesis, and parcel-specific verification guidance. Read our editorial standards.
Parcel identity and jurisdiction
Collect the APN, current assessor record, recorded parcel or tract map, legal description, city-limit or unincorporated-county confirmation, zoning result, general-plan designation, and applicable overlay maps.
Title, access, and restrictions
Review the preliminary title report, recorded easements, road or maintenance agreements, covenants, HOA documents, mineral or water rights where relevant, liens, and exceptions that may affect construction or utility routes.
Site and infrastructure records
Request surveys, topography, grading history, drainage information, prior permits, code-enforcement records, septic and well files, utility will-serve or availability letters, fire-access information, and any geotechnical or environmental reports.
Turn records into unresolved questions
A document packet is useful only when contradictions and missing items are identified. Create a dated list showing what each record confirms, what remains unverified, which agency controls the answer, and whether the purchase contract provides enough time to investigate.

Frequently Asked Questions
Is there one statewide answer for this issue?
No. California rules create starting points, but parcel-specific local confirmation is required.
Which department should I contact first?
Start with the planning department for the parcel's city or unincorporated county area, then confirm building, utility, environmental health, and fire authority requirements as needed.
Can I rely on this guide instead of contacting local officials?
No. Use this guide to organize questions and documents, then confirm the answer directly with the appropriate local departments before spending money or submitting plans.
