What we measure
Every attribute is a building fact with a date and an evidence level. We do not collapse dimensional data into a single undefined checkbox.
Direct answer
We record falsifiable building attributes—door clear widths, threshold heights, shower curbs, route widths, control heights, and related items—against a published glossary aligned to RESO AccessibilityFeatures. Each row carries a date and an evidence level.
How is provenance recorded?
Each measurement carries evidence such as measured onsite, photo verified, agent reported, or floorplan derived—plus who verified it and when. That record is the product.
Layout rule for any future MLS join: measured data renders in a separately attributed panel — never merged into MLS feature lists.
Which attributes appear in the working glossary?
Zero-step entry
A route from the arrival point to the primary entrance with no stair and no abrupt level change. Thresholds, if present, are low and beveled.
Covered landing at entry
A weather-protected floor surface immediately outside the primary door, large enough to wait, unlock, and maneuver while the door swings.
Door clear width
The open width of the doorway measured between the face of the door and the stop, with the door open 90 degrees.
Interior route width
Clear width of hallways and other interior routes used to reach bedrooms, bathrooms, and the kitchen.
Turning space
A clear floor area that allows a 180-degree turn, typically in kitchens, bathrooms, and at the end of a hall.
Single-level floor plan
Primary living, cooking, sleeping, and bathing rooms on one finished floor, with no interior stair between them.
Ramp slope
Running slope of any ramp used in place of stairs on the arrival route.
Roll-in shower
A shower compartment with no curb, or a low transferable threshold, and clear floor space to enter.
