Shed & Boundary Encroachment Cost Risk Tool
Assess your likely next steps and total cost exposure when a neighbor's structure appears to cross your property line.
Get a cost-risk snapshot before you confront your neighbor
The Shed & Boundary Encroachment Cost Risk Tool helps you estimate the likely first steps and total cost exposure if a shed, fence, driveway/pad, wall, or landscaping appears to cross a property line. It’s designed for homeowners who want a practical plan: document what you can, decide whether a survey is needed, and understand when negotiation or formal action may be worth it.
How the tool turns your inputs into a next-step plan
First, it scores encroachment likelihood using (1) visible indicators (none/possible/likely/obvious), (2) estimated overlap extent, and (3) what property-line documentation you already have (deed, old survey, recent survey). Those inputs are mapped to a scenario class: suspicion only, probable, confirmed, or disputed boundary. Then it recommends the most sensible path based on your escalation preference (keep informal through fast legal action) and computes a total cost range by adding typical bands for evidence gathering, surveying, mediation/attorney consult, and possible removal/relocation/repair.
Why “it looks wrong” doesn’t always mean “it’s certain”
Your confidence level depends heavily on documentation quality: deed-only typically means you’re confirming the boundary, not proving encroachment. The tool also treats overlap extent as a risk multiplier—large overlap (especially with sheds, driveways/pads, or walls) pushes removal/abatement costs higher. Even when indicators seem strong, some disputes are boundary-adjacent (shared boundary features, measurement differences, or unclear prior surveys), so the tool focuses on planning actions rather than determining ownership.
Important caveats that affect real-world costs
This calculator provides rough planning ranges, not legal advice or a case-value estimate. Local land-law factors (adverse possession, easements, HOA rules, and building-code/permit requirements) can change both strategy and costs, and they aren’t fully modeled here. Removal/relocation assumptions also may not cover utilities conflicts, demolition hazards, or site-access limitations—those can substantially increase the “high-cost” end of the range.
Handling tricky inputs (and what the tool will assume)
If you choose “visible indicators = none,” the tool won’t accept overlap values like small/moderate/large unless you’re explicitly signaling uncertainty—because that combination would conflict. It also prevents incompatible documentation entries (for example, “recent survey” alongside “no records”), and it applies higher default removal-cost expectations for driveways/pads and walls than for fences. If you select “keep informal,” the tool will only suggest faster escalation when confidence is high and overlap is large.
