ParapetGet early access
Built for SB-4D & SIRS compliance

Scan a building.
Get a compliance report and a reserve forecast.

Parapet turns a phone's LiDAR scan into the structural condition report your milestone inspection requires, and the reserve-fund forecast your association needs to plan around it — from one walk of the property.

Introducing Parapet

Today's structural inspection is manual. An engineer walks the property with a tape measure, takes notes and photos, then separately builds a compliance report and a financial forecast in different tools. It's slow, inconsistent, and expensive — and it's now legally mandatory on a fixed schedule for a huge number of buildings.

Parapet replaces the tape measure and the spreadsheet with a phone. It captures the building in 3D, flags defects as it goes, and turns one scan into both the report and the forecast an association needs.

Unlimited coverage

Every component of a building, captured in one walk.

Structural frameRoofFacade & claddingWaterproofingBalconiesFoundationDrainageRailingsExpansion jointsParking structureStucco & coatingsSealants

No separate walkthrough for each system. One scan builds a full condition inventory across the structure, envelope, and shared infrastructure the milestone inspection covers.

3D LiDAR capture

Walk the property once. ARKit and the phone's LiDAR build a real-time 3D model of the structure as you go.

Automatic defect detection

A computer-vision model flags cracking, spalling, and corrosion staining directly on the scan, no separate photo review.

Two outputs, one scan

The same walkthrough produces the compliance report and the reserve-fund forecast — built together, not stitched from two tools.

Compliance report

The milestone inspection report, generated from your scan.

Parapet assembles the condition inventory into the structural report your jurisdiction's milestone inspection and SIRS require — organized by component, ready to review and sign off.

Reserve funding trajectory
Recommended funding Current reserves
Reserve-fund forecast

How much to save, and on what timeline.

The same scan feeds a reserve-fund forecast: what the association needs to set aside, and when, based on the actual condition of the building's components.

Defect detection

Cracking, spalling, and corrosion — flagged as you walk.

A computer-vision model reviews the scan for the defects a milestone inspection looks for, and attaches them to the exact location on the building.

Why now

The pressure is legal, recurring, and expanding state by state.

Florida

SB-4D

Mandates milestone structural inspections and Structural Integrity Reserve Studies (SIRS) on a fixed schedule, with real financial penalties for missing them.

New Jersey

Recurring reserve law

Passed a near-identical recurring reserve-study requirement. Other states are watching Florida's rollout to decide how much of it to copy.

Federal · Jan 2027

FHFA reserve rule

Condo associations nationwide must fully fund capital reserves before units qualify for Fannie Mae or Freddie Mac-backed mortgages.

New York City

Local Law 11

A separate, established facade inspection market Parapet's capture and detection layer extends into directly.

The plan: start in Florida, expand state by state as more adopt similar laws, and move into NYC's Local Law 11 facade inspection market.

Differentiation

Facade-defect tools capture and flag damage, but aren't built for phone-native 3D capture or reserve forecasting. Reserve-study software builds the financial forecast, but has no visual capture layer at all — engineers still gather the condition data by hand and enter it separately.

Parapet combines phone-based 3D capture, defect detection, and financial reserve forecasting in one workflow. That combination, not any single piece of it, is the wedge.

Built for the engineers who keep buildings standing.

Bring the compliance report and the reserve forecast into one workflow, starting with your next milestone inspection.
