Start by identifying exactly what the surveyor marked
Do not hand a contractor a survey drawing and assume every line has the same meaning. Property boundaries, easements, building setback lines, rights-of-way, and occupation features can all appear on one plan. Ask the surveyor which physical markers correspond to the relevant boundary and whether the requested line was staked between corners.
Photograph the visible markers and nearby fixed features before construction. A photo does not replace the survey, but it preserves context if a stake is disturbed after crews, pets, weather, or landscaping reach the site.
Resolve local rules before choosing the final layout
Fence rules are local. They can change with height, yard location, corner visibility, pool use, zoning district, easements, and homeowner-association restrictions. The fact that one city offers a fence permit does not mean every city uses the same trigger. For example, Centennial, Colorado and Orlando, Florida publish different local processes and design constraints.
Ask the permit office one concrete question: “For this address, height, material, and yard location, what approval and site-plan information are required?” Then separately check recorded easements, private covenants, and HOA rules. A permit approval does not necessarily resolve private property rights.
Talk to the neighbor with evidence, not a demand
Share the proposed layout before excavation when a fence will run near an occupied boundary. Show the drawing and markers, explain the planned offset, and ask about gates, drainage, vegetation, or access concerns. The purpose is to catch a practical conflict while moving a line or gate is still easy.
If the neighbor disputes the boundary, pause the layout conversation. Refer the technical question to the surveyor and legal rights to a qualified local attorney. A contractor should not be asked to decide which boundary evidence controls.
Create one scope that every contractor prices
Estimate comparisons fail when each contractor receives a different version of the job. Write down:
- measured fence length and planned height;
- material, finish, post size, and gate count;
- old-fence removal, brush clearing, roots, and haul-away;
- who obtains permits and supplies required drawings;
- the intended post offset from the surveyed boundary;
- utility-location, irrigation, access, cleanup, and restoration responsibilities;
- start conditions, payment milestones, and change-order rules.
The Federal Trade Commission advises homeowners to compare written estimates and understand the contract before paying for home-improvement work. Its contractor guidance also recommends checking credentials, insurance, references, and payment terms.
Separate the boundary decision from the digging decision
A boundary survey answers where the property boundary is under the applicable evidence and standards. A utility locate addresses buried utility markings before excavation. These are not interchangeable. Contacting 811 is part of excavation planning, and the national 811 guidance says to submit a request before digging and wait for the required response in your state.
Also tell the contractor about private irrigation, lighting, septic components, invisible pet fencing, or owner-installed lines. Public utility-location systems may not mark privately owned facilities.
Put the post-location rule in writing
“Build near the line” is not a usable instruction. The contract or approved layout should state whether the face, center, or another part of each post follows a measured offset from the surveyed boundary. The FTC's contractor guidance likewise recommends a written contract that identifies what the contractor will do. The fence agreement should also say who approves field changes when roots, utilities, grade, or structures block the intended position.
Do not invent a universal six-inch or twelve-inch setback. The appropriate position depends on local rules, easements, the fence design, survey evidence, maintenance needs, and the owner's risk tolerance.
Document the installation before the evidence disappears
Before work begins, save the signed survey, permit, approved layout, contractor scope, and dated photos. During installation, photograph representative posts with nearby markers still visible where practical. At completion, record approved field changes and keep the final invoice and warranty with the survey. This complements the FTC's advice to keep the contract and related project records.
This file is useful for future maintenance, a sale, or a neighbor question. It cannot prove that construction followed every requirement, but it is far better than reconstructing the project after the crew and stakes are gone.
