ScanADA

Every HUD recipient is required to keep a Section 504 self-evaluation and transition plan current. Most do not, because the work is a clipboard, a tape measure, a level and a week of someone’s time per property. When the review notice arrives, the first question is always the same: show me what you found and what you did about it. ScanADA uses the LiDAR scanner in every iPhone Pro to document the physical accessibility condition of a property, one unit and one sidewalk at a time, and records what is there, how it was measured and where. It does not score, certify or replace a qualified surveyor’s judgment. It produces the record that judgment rests on.

Who it is for

Built for

PHA and owner staff keeping a 504 self-evaluation current, accessibility consultants doing formal audits, residents and advocates who need a timestamped record, and architects and contractors verifying a punch list.

What is in it

What we are building

One walk, three screens. Scan: LiDAR builds the plan, finds walls, doors, fixtures and grab bars, and marks the 60 inch turning space. Measure: elements the sensor can read reliably are recorded automatically and labeled LiDAR; anything below its resolution is flagged amber to confirm with a tape and a photo. Record: each element carries its observed value, method, photo and location, with the standard’s requirement beside it. Nothing is scored.
Three measurement tiers, stated on every line. LiDAR for clear floor space, turning space, route width, counter and sink rim height, reach range, slopes, parking and handrail height. Confirm for door clear width, grab bar length and blocking, knee and toe clearance, landing size. Manual for thresholds, changes in level, riser uniformity, door force, signage and detectable warnings.
Three standards, chosen per building and area from construction date, funding and building type: UFAS, the 2010 ADA Standards under HUD’s deeming notice, or the Fair Housing Act design requirements. One site can need all three. Every finding cites its section.
Exterior too. Sidewalks, curb ramps, stairs and parking lots scan as continuous runs, split into segments and pinned on a site map so a crew can find each one and a re-walk returns to the same spot. Exports to GeoJSON for ArcGIS.
The review binder: cover and scope, sample and coverage, one page per element with photo, method and section, floor plans and site map, correction tracking with before and after photos, and a certification that states observed conditions on the date shown, not a determination of compliance. Exports as PDF, XLSX and GeoJSON.
After the walk, findings live in a property record with an owner, a target date and closure evidence, and generate a draft self-evaluation summary, a transition plan schedule and work orders.
Privacy: scans of occupied units are resident data. Processing runs on device or in controlled storage with a stated retention policy, and people and personal items are blurred in interior photos by default.
Requires an iPhone 12 Pro or later Pro model, or an iPad Pro from 2020 on. Works offline, uploads when connected.

Progress

Where it stands

Concept
SpecFeature set specified: measurement tiers, standard selection, binder format, exports.
Phase 1 buildInterior unit and common area walk under UFAS and the 2010 ADA Standards, with PDF and spreadsheet export. Not started; pilot partners being recruited.
Phase 2Exterior capture and the site map.
Phase 3Fair Housing Act design requirements and the consultant tier.
Launch

Next upRecruit three to five housing authorities or owners with a review on the calendar in the next twelve months, and one or two accessibility consultants, as pilot partners. They walk real properties, get the reports and set the phase one priorities.
