This is an interactive product preview using illustrative data. It shows the intended decision flow without claiming the processing backend is already live.

01

Start with one clear input

sample

No file is uploaded here. A production version would show retention choices before transfer.

The experience advantage

Less anxiety. More visible progress.

The competitors prove the job exists. LotLight improves the moment between input and decision: uncertainty is reviewable, sources stay attached, and the useful output arrives before a dashboard.

Answer first, map second

The first screen shows a plain-language feasibility signal instead of a waitlist or a statewide directory dump.

Rule layers stay visible

State rights, local dimensional rules, overlays, transit proximity, and wastewater questions never collapse into one false yes/no.

Freshness is part of the answer

Every claim shows its source, retrieval date, and whether the town has newer material requiring review.

The better way

One complete path from input to next action.

  1. 1

    Confirm the parcel

    Match an address to a parcel and let the homeowner correct a bad match.

  2. 2

    Build the rule stack

    Apply statewide ADU protections, then surface local restrictions and unresolved overlays.

  3. 3

    Leave with a call sheet

    Export the likely path, cited facts, unknowns, and exact questions for the building department.

Pricing without make-believe

Free where the market is free. Paid where the work continues.

There is no honest numeric discount yet. LotLight prices the first useful job instead: a $9 cited ADU brief without a subscription.

The trust boundary

Useful preflight, clearly short of approval.

LotLight is an early feasibility aid, not an official zoning determination, site plan, building permit, septic approval, or professional opinion.
