About ZoneMapper
ZoneMapper is a free, browser-based tool that helps homeowners, contractors, and permit applicants create professional zoning permit site plan maps — without expensive CAD software or hiring a surveyor.
Upload your property survey or map image, trace your lot boundary, mark your setbacks, and annotate structures. ZoneMapper calculates lot coverage, generates a buildable envelope, and exports a clean, labeled site plan ready to attach to your permit application.
No account required. No data uploaded. Everything runs locally in your browser.
I built ZoneMapper because I went through the permit process myself and couldn't find a simple, affordable tool that did this one job well. If it saved you hours of frustration (or a few hundred dollars in drafting fees), consider buying me a coffee — it keeps the lights on and helps me keep it free for everyone.
