Living in wine country: parcel-level due diligence

Check the parcel jurisdiction, zoning and permitted uses before planning a residence, agricultural use or business.

What to collect

Confirm access, utilities, water supply, wastewater arrangements, fire requirements and insurance at parcel level. Marketing acreage and neighborhood labels do not establish development rights.

Official starting points

• Riverside County parcel tax bills

• TVUSD boundaries and enrollment

• City of Temecula departments and services

Finding help with water or plumbing systems

Identify the property's actual water supply and wastewater system before requesting work. Ask whether the business handles that system and serves the exact address. Start with the Temecula Valley plumbing directory for contacts and hiring questions; directory inclusion does not establish specialist capability or confirmed coverage.
