It brings together basic property details in one place, which can help confirm search information before using official county systems or contacting specific offices for complete records.

Before starting a search, it helps to have a few key details on hand.

Searches can also be done by the property's address or the current or previous owner's legal name.

Beyond online access, the office accommodates research through public terminals for self-service lookups. While the office cannot perform searches via telephone, requests for document copies may be submitted via email or sent by mail.

Copies of recorded documents are available for a fee of $0.50 per page, up to a maximum of $35 per document. Meanwhile, certified copies are available for a flat fee of $35 per document.

While the county tracks ownership and tax data, local municipalities handle building permits, inspections, and zoning codes that may be more restrictive than county-wide guidelines. Records can also vary across jurisdictions, as each municipality may use its own software for tracking permit histories, inspection results, and municipal liens.

When in doubt, checking the property's jurisdiction through the county's GIS portal is always a good first step.
