accuracy vs field measurement
The problem
“The listing says 850 sqft. The tenant measured 780. Now they want a rent reduction.”
Wrong measurements in leases create disputes, insurance gaps, and mispriced rents. When you can't back up the number with documentation, you lose the argument by default. PlanSnapper gives you a measured floor plan and a PDF you can point to.
Where it fits
How property managers use PlanSnapper
Lease documentation
Accurate measurements in every lease. When a tenant challenges the listed size, you have a measured floor plan with a PDF to back it up.
Insurance records
Insurers price premiums and calculate rebuild costs from square footage. Wrong numbers mean wrong coverage. Documented measurements protect you at claim time.
Rent pricing by sqft
Charge rent proportional to actual size. In multi-family buildings with mixed unit types, accurate per-unit measurements keep your pricing fair and defensible.
Renovation planning
Calculate flooring, paint, and material quantities from the floor plan before work starts. No site visit needed to generate an accurate materials estimate.
Tenant handover disputes
When a tenant claims the unit is smaller than listed, show them the measured floor plan and the PDF. Documented measurements end the argument.
Portfolio documentation
Build an accurate size record for every unit across your portfolio. One measurement per floor plan type: reuse for matching layouts.
How it works
Measured and documented in minutes
Upload the floor plan
Drop in a PDF, JPG, or PNG of any to-scale floor plan. From an architect, CubiCasa, Matterport, or a photo of a printed drawing. Works with any format.
Trace the unit perimeter
Click around the exterior walls. Add separate polygons for storage areas, garages, or common spaces you want to measure independently.
Set one known wall length
Click two endpoints of any labeled dimension and enter the real-world measurement. PlanSnapper calibrates every other measurement from that single reference.
Export for your records

Built by an appraiser. Used by professionals.
I built PlanSnapper because I was tired of printing floor plans and measuring them with a ruler. Now I verify GLA from my desk in minutes. It’s completely changed my appraisal workflow.
