Buildable Envelope Planner

Buildable Envelope Planner turns zoning research into an instant, visual feasibility check: draw your lot, enter the local restrictions, and see exactly what you can build.

WHY IT'S DIFFERENT

Most lot calculators collapse everything into one number. This app keeps the four figures that actually matter separate and clearly labeled, the way an architect or planner thinks about them:

- Lot area: the raw parcel

- Setback envelope: what's left after required setbacks

- Max coverage area (COS/CUS): the footprint limit

- Max counted floor area (FAR): the total buildable area across floors

CORE FEATURES

- Draw any lot shape by tapping vertices, or enter dimensions directly

- Apply front, rear and side setbacks and instantly see the resulting buildable envelope

- Multi-story massing: stack floors, apply height limits and upper-floor setbacks, and preview the massing

- Parking layout: place vehicle bays (compact, sedan, SUV, pickup presets) and validate them against your lot and parking requirements

- Scenario comparison: build multiple massing options side by side and compare their feasibility

- Regulatory sources, easements, terrain and existing buildings, so every input stays traceable back to where it came from

- Export a professional PDF feasibility report or a CSV area schedule
