Put each question with the right evidence

Separate land-use authority, building records, utility service and recorded rights. The answer to one does not establish the others. County jurisdiction does not mean every service comes directly from the county, and a traveled access route does not by itself establish the maintenance agreement.

The county’s property and zoning research page distinguishes mapping, permit history and records requests. Use each for its intended purpose. Missing online plans are not evidence that no plans exist; equally, a permit number alone does not establish final approval of the feature you see.

Buying outside city limits

Use the property-responsibility ledger to identify the material unknowns and the appropriate next request. Describe proposed uses precisely when seeking an agency answer. A neighboring property’s configuration does not establish permission for your parcel.

For rural property, investigate actual service arrangements and access. For established neighborhoods, focus on altered space and major systems. For a Delta or hillside site, add the relevant physical and insurance questions rather than applying one checklist to every address.

Selling an unincorporated property

Prepare a clear jurisdiction and services summary alongside the improvement history. Provide the records that explain shared obligations, significant structures and known completed work. Identify gaps so they can be disclosed and investigated rather than concealed by general claims about potential.

Contra Costa seller representation connects that file to preparation and pricing; the buyer service supports comparing a county property with city alternatives.
