Zavia GIS turns public environmental and land-use data into clear maps and desktop screening reports — so you spot floodplains, wetlands, conservation areas and other mapped constraints before they cost you tens of thousands.
Floodplains, wetlands, watercourses, woodlands, regulated areas, natural heritage features, zoning overlays. A property can look fine on a listing and still carry constraints that affect your offer, your design, your permit timeline, or your build cost.
Zavia GIS reads the public maps before you commit — and gives you a clear, plain-English report so you can ask better questions earlier.
A $249 screening helped one client identify a mapped wetland buffer affecting 2.4 of 5 acres before closing — information they used to renegotiate $40,000 off the price.

No. Zavia GIS provides preliminary desktop screening and GIS mapping support using public data. It does not replace a Phase I/II ESA or professional regulatory review.
No. Zavia GIS does not provide buildable / not-buildable conclusions. We help identify mapped constraints and suggest questions to ask the relevant authority or qualified professional.
A property address, parcel number if available, listing link if available, and a short note on what you're trying to do.
Simple property scans typically take 2–3 business days. More complex map packages may take 3–5 business days.
We are deliberately scoped — the more honest we are about what we do and don’t do, the better the work we deliver.
For any of the above, we will tell you honestly and recommend the right type of qualified professional to escalate to.
Zavia GIS is designed for early-stage decisions. If the screening identifies potential concerns, the next step may be to speak with the relevant municipality, Conservation Authority, planner, surveyor, engineer, or environmental consultant.
Is the property near or inside a Conservation Authority regulated area?
Is there a mapped wetland, woodland, watercourse, or floodplain nearby?
Should I contact the municipality or Conservation Authority before waiving conditions?
Do I need to speak with a planner, surveyor, engineer, lawyer, or environmental consultant?
Are there mapped constraints that may affect future plans for a renovation, severance, or custom build?
We tell you what to ask and who to ask it to — before you spend more.
Tell us what you're trying to do. We'll recommend the right screening package and confirm pricing within one business day.
