# Data updates

> How often BPD data is refreshed, custom cadences, and how to stay current.

## Update cadence

BPD updates each county a **minimum of twice per year**. In practice, many counties are updated more frequently based on customer demand and data availability.

Custom update cadences are available for customers with specific freshness requirements. For example, high-priority counties can be updated monthly if the county publishes data at that frequency.

***

## How update priorities work

Update frequency is driven by two factors:

1. **Customer demand**: counties with active customers are prioritized for more frequent updates
2. **County data availability**: updates happen when counties publish new data; BPD cannot update faster than the source

If you need a specific county updated more frequently, contact [support@buyparceldata.com](mailto:support@buyparceldata.com) to discuss options.

## What's included in updates

When a county is updated:

* New parcel records are added
* Existing records are refreshed with the latest assessor data
* Coverage gaps in that county are reduced as new data becomes available

**Updates are included in your subscription.** There is no additional charge for coverage expansions, data improvements, or new counties added within your licensed area.

## Frequently asked questions

**Do unused parcels roll over?**
No. Monthly API parcel limits reset to zero on the first of each month regardless of prior usage.

**If a county is updated, do I need to re-query it?**
Only if you're caching results. The API always returns the latest data. Flat file customers receive updated files on their agreed cadence.

**Can I request a county be added sooner?**
Yes. Contact [support@buyparceldata.com](mailto:support@buyparceldata.com) and customer requests influence prioritization.
