Use cases

• Prioritize high-risk Seattle URM buildings with no visible retrofit for structural engineers.
• Screen a purchase for URM status by address.
• Study risk across neighborhoods for planning and insurance.

Coverage and freshness

Program: Seattle Unreinforced Masonry (URM) Buildings. Publisher: Seattle Department of Construction and Inspections. Area in this example record: Seattle, WA. Each run reads the current official publication, so a scheduled run picks up new releases when the agency publishes them. Fields the program does not publish come back as null.

Pricing

This actor uses pay-per-event pricing. These are the current Apify prices, read on 2026-11-06.

Event	Price	When it is charged
result	$0.015	Each building delivered to your dataset
apify-actor-start	$0.003	When a run starts, once per GB of run memory with a minimum of one

At the default 512 MB, a run that delivers 100 buildings costs $1.503.

• Accounts on the free Apify plan receive up to 10 results per run.
• If nothing matches your filters, no results are charged. If the source cannot be read before any result is saved, you get one row with an error field, and that row carries no result charge. The start event still applies to the run.
• Set a maximum cost per run and the actor stops delivering results when it reaches that limit.
