Methodology & data sources
- Asking prices and medians
- There are 22 active for-sale and 11 active for-lease listings in Ottawa, IL. The medians are based on 5 of the for-sale and 4 of the for-lease listings, those that state a price or rent per square foot. These are ASKING figures from live listings, not closed-transaction prices, and a figure resting on fewer than 10 listings says so where it is quoted.
- Vacancy rates
- Published per-sector market series, taken at the metro level where one exists and otherwise at the Census-region level — a chart reading "in <region> region" is a regional number, not this city's.
- Zoning and land use
- The current municipal zoning release: 8,102 zoned acres across 14 districts. Shares are of zoned land, so parcels the release leaves unclassified are excluded from the mix.
- Refresh
- The monthly aggregates close at the end of the previous month, so 31 October 2026 — not today — is the honest last update.
- Known limitations
- office vacancy is reported at Midwest region level, retail vacancy is reported at Midwest region level, industrial vacancy is reported at Midwest region level and asking prices run materially above recent closed pricing.
- Coverage
- Metrics below the 10-observation threshold fall back one geographic level. The geography used is named on each figure.
