San Antonio Flex Asking Rent — September 2026
76% of recorded listings don't state a rent with a unit. The citywide median of stated asking rents that convert is $21 per square foot per year (n=419).
Fact Lease tracks San Antonio commercial asking rents over time.
Part of the San Antonio Commercial Asking Rent Snapshot — September 2026.
Median asking rent
USD per square foot per year: Median not published (n below 5). None is invented.. n=1.
No min–max is published when n is below 5.
Plausibility band for the printed min–max: $3–$80 per square foot per year. 0 readings fall outside that band and are omitted from the printed range. The printed range is the full converted cohort.
Sample composition
No stated postal code is more than 30% of this class cohort in the USD-per-square-foot-per-year readings. A warning requires at least 5 converted readings in the cohort.
Cohorts that were not converted
Every stated rent in this class was either normalized to USD per square foot per year or excluded because its unit was not stated. No separate monthly or unspecified-per-square-foot median is published.
Stated postal codes
No stated postal code in this class has 5 or more readings in the USD-per-square-foot-per-year cohort. Smaller groups stay in the class median and are not tabulated.

Method
Observation window: 2026-09-01 through 2026-09-30, UTC. A date is the day a public page was read, not a lease start. Published readings in this window run from 2026-09-23 through 2026-09-25.
Each published suite contributes its newest observation in that window. An older reading on the same suite is not a second point.
2085 suites have a reading in the window. 502 of those state a base rent with a unit. A null base rent is excluded from every median. Null does not mean zero.
24 duplicate readings were collapsed before the medians. A duplicate is the same address, suite label, rent, unit, and area. A blank address is not merged with another suite. The n under each median is the count after that collapse.
USD per square foot per year is the primary unit. A rent stored as $/SF/yr is used as stated. A rent stored as $/SF/mo is multiplied by 12. That is a unit conversion of a stated rate, not a new rent. A rent stored as $/month is converted only when area is stated and greater than zero: monthly rent times 12, divided by the stated square feet. A rent stored as $/year is divided by stated square feet the same way.
A rent stored as $/SF (period not stated) is not converted. The page did not say year or month. Those readings have their own median, labeled period not stated.
A monthly rent with no stated area stays in a USD-per-month median. It is not divided into a per-square-foot rate.
A stated amount with no stored unit is excluded from every median. The amount remains on the suite page. A non-positive rent is not used. This snapshot does not replace any excluded figure with an estimate.
108 stated rents remain outside every median after deduplication because the unit could not be used under those rules.
The printed min–max uses a plausibility band of $3 to $80 per square foot per year. A converted reading outside that band is omitted from the printed range. It stays in n and in the median. 8 citywide converted readings fall outside the band. No excluded figure is replaced with an estimate.
The median is the middle value after sorting. An even count uses the mean of the two middle values only. The arithmetic mean of the cohort is not published. A median is not published when n is below 5. The count is still printed. None is invented.
138 converted readings have no stated use type. They stay in the citywide median. They are not a headline asset class, they are not given a class page, and they are not moved onto office, retail, industrial, or flex.
When one stated postal code is more than 30% of a cohort, and that cohort has at least 5 converted readings, the snapshot prints a composition warning. The warning is a share of readings, not a submarket name.
This snapshot does not yet have its own Zenodo DOI. The Fact Lease ledger deposit is https://doi.org/10.5281/zenodo.22923838. When a snapshot version is deposited, this page publishes that DOI.
Readings are suite observations, not buildings and not closed leases. Source type is Public web page. Evidence older than 7 days is Not re-read in 7+ days on the suite page. This snapshot does not drop a reading for age.
Caveats
These are asking rents printed on public pages, observed on the dates above. They are not closed transactions, not effective rents, and not a confirmation that the suite is available.
Rent units in the source pages are inconsistent. Some state dollars per month, some state dollars per square foot per year, and some state a per-square-foot figure without a period. This snapshot does not guess the missing period.
Listing headlines are not treated as building names on suite pages when the observation states an address. The medians do not depend on the headline.
One property with many suites can dominate a postal code. This is not a building-weighted index.
Plausibility band for the printed min–max: $3–$80 per square foot per year. 8 readings fall outside that band and are omitted from the printed range. Those readings stay in n and in the median.
Flex observations list the underlying suite pages. Citywide snapshot. How the median is counted. Methodology. Stated-rent JSON is the same published fields, filtered.
