Pick a parcel. The real building footprint loads, the system sizes itself to Arizona code, and a clean black-and-white engineering plan sheet comes out the other side. No blank-page CAD, no guesswork, no waiting on a site visit to get a working draft.
Founding access for Arizona. Maricopa is live today. The rest of the state is loading.
Most "AI" design tools invent something plausible and hope. Ours runs a real engineering pipeline: recorded county records, machine vision, learned local practice, deterministic code sizing, a geometric placement solver, and a standing backtest. Watch the data move.
Every generation is anchored to what county engineers actually installed on nearby parcels, then validated against the recorded record. The numbers are the proof, and the harness is re-runnable.
We OCR'd 113,000 recorded Maricopa County septic as-builts: tank sizes, system types, dispersal, drainfields, soil and perc. That corpus is the ground truth the generator learns local practice from.
113k recorded as-builtsA deterministic engine sizes the tank and dispersal to Arizona ADEQ and county code, then biases every choice toward what is actually installed in that ZIP. Real footprint, real placement solver, not slop.
ADEQ + county calibratedWe re-run the generator against the recorded as-builts and measure the match. Tank sizing lands within a step 89% of the time and treatment type matches 99.7%. The match rate is the proof, and it is re-runnable.
Re-runnable backtestAnyone who needs the parcel and what is in the ground: septic designers and engineers, plus pool, landscape, ADU, solar, well and fence contractors, and inspectors.
No blank-page CAD, no waiting on a site visit to get a working draft. Pick a parcel, get a code-calibrated plan in seconds.
Replaces a $700-1,500/yr generic stack (AutoCAD LT + Bluebeam + free sizing). The only AZ / MCESD-code-specific tool.
Pull the actual recorded county as-built straight from the record — compare the generated design to the real thing side by side.
Works for pool, landscape, ADU, solar, well, fence contractors and inspectors — anyone who needs the parcel + what is in the ground.
We are opening Parcel Perfect Septic to 25 founding Arizona accounts before the public launch. Founding seats lock in launch pricing, get first access as each county comes online, and help shape the tool.
