What happens if you skip the permit (and you needed one)
- Stop-work order issued by Lombard Building Department; fence must be removed or modified; $250–$500 fine plus cost of remediation if structural or sight-line violation confirmed.
- Insurance claim denial if fence damage or injury occurs — homeowner's policy typically voids coverage for unpermitted structures, and you become liable personally.
- Title disclosure hit at resale: Lombard requires disclosure of unpermitted structures on residential sales; realtor or buyer's inspector flags it, forcing removal or retroactive permit fees (often 1.5x the original fee) before closing.
- Neighbor complaint triggers code enforcement; complaint-driven inspections in Lombard often cost more in removal/remediation than a $100–$200 permit would have upfront.
Lombard fence permits — the key details
Lombard's primary fence rule hinges on height and location. Wood, vinyl, and chain-link fences under 6 feet in side or rear yards are permit-exempt — the most common scenario for residential properties. However, that exemption evaporates if your property is a corner lot or the fence is in the front yard. Corner lots in Lombard must maintain sight-line triangles at intersections: a 20-foot radius (or local variance) from the corner, and no fence taller than 3.5 feet in that zone, per the zoning ordinance sight-distance standards. This rule protects traffic visibility and is enforced aggressively during inspections and neighbor complaints. If your corner-lot fence violates the sight triangle, you'll be forced to cut it down, relocate it, or remove it entirely. Always check your property deed and survey for corner-lot designation before ordering materials.
Masonry fences (brick, stone, concrete block) operate under different thresholds. Any masonry fence over 4 feet requires a permit in Lombard, regardless of location. The reason is structural: masonry over 4 feet must have a frost-protected footing that extends 42 inches below grade in the Lombard area (ICC-sourced frost-depth data for DuPage County). A footing detail signed by a structural engineer or showing IRC R403.1 compliance (concrete pad at least 12 inches thick, reinforced steel in certain soils) is standard. Without proper footing documentation, masonry fences fail inspections and must be rebuilt. Plan on 2-3 weeks for permit review if your footing design is sketchy; plan on a full re-pull if the inspector finds the footing is only 18 inches deep post-construction.
Pool barriers fall under a separate, non-negotiable track. Any fence or barrier protecting a residential pool — regardless of height — requires a Lombard permit and must comply with IRC AG105 (model code adopted into Illinois residential code). The key rule: self-closing, self-latching gate hardware, tested and labeled, is mandatory. The gate must not remain open more than 15 seconds; hinges must be stainless steel or equivalent corrosion-resistant material; and the gate opening must not exceed 1/2 inch. Inspectors test the gate mechanism on final; if it sticks open or the latch doesn't hold, you fail. This is one area where Lombard (and all Illinois municipalities) enforces aggressively because child-drowning liability is catastrophic. Budget an extra $400–$800 for compliant hardware and inspection cycles.
Lombard's building department operates a hybrid intake system. Basic residential fence permits (under 6 feet, non-masonry, rear/side yard, straight sketch) can often be pulled over-the-counter or via phone if you have a clear site plan showing property-line dimensions, proposed fence location, height, material, and setback distance from the property line. Fees are flat: typically $75–$150 for a standard residential fence, depending on linear footage (some jurisdictions charge $0.50–$1.00 per linear foot). Corner-lot fences, masonry, and pool barriers go to full plan review, which takes 5-7 business days and costs $150–$250. The city's online portal (verify via Lombard.org or call the Building Department directly at 630-620-7456) allows you to upload sketches and track status; some permits are approved digitally same-day.
Setback distances and HOA restrictions are separate. Lombard zoning allows 0-foot setback from rear property lines (fence on the line itself is legal), but front-yard fences require 5-foot setbacks from the front property line. Side-yard setbacks vary by zoning district (typically 0-2 feet). If your property is in a Homeowners Association, the HOA CC&Rs almost always impose stricter fence rules — color, material, height, setback — than the city code. Permit rejection due to HOA violation is not the city's responsibility, but HOA denial will block your permit application because you lack proof of HOA approval. Always obtain HOA sign-off in writing BEFORE filing with the city. This step is invisible to Lombard's building department but deadly to your timeline: HOA approval can take 2-4 weeks.
Three Lombard fence (wood/vinyl/metal/chain-link) scenarios
Frost depth, soil, and why Lombard's 42-inch footing rule matters
Lombard sits in a glacial-till zone with localized loess deposits (western portions) and clay-heavy soils typical of DuPage County. The frost depth for the Chicago metro area (which includes Lombard) is 42 inches below grade. This is not a suggestion — it's the ICC standard adopted into Illinois residential code and enforced by Lombard inspectors. A fence post or masonry footing that doesn't extend 42 inches below grade will heave (lift) when the soil freezes in winter, cracking mortar, uprooting posts, and creating an unsafe structure by spring. Many homeowners cut corners and set posts 24-30 inches deep; these fail within 2-3 winters in Lombard. An inspector will flag post depth during a footing inspection (for masonry) or during final inspection (for wood/vinyl posts). If posts are too shallow and concrete is already set, you will be ordered to remove the fence, reset posts deeper, and rebuild — a costly correction that could run $2,000–$5,000 depending on linear footage.
For masonry walls, a concrete footing should be at least 12 inches thick, extend the full width of the wall, be positioned below the frost line, and sit on undisturbed or properly compacted soil. Lombard inspectors often request a geotechnical report for masonry walls over 4 feet or in areas with fill or poor soil conditions. For wood and vinyl, concrete footings around 4x4 posts should reach 42 inches and be backfilled with concrete to 6 inches below grade, with gravel drainage at the base. The reason for the specificity: DuPage County's seasonal freeze-thaw cycle is aggressive — early hard freeze followed by January thaw, then another freeze — creates heaving pressure that weaker footings cannot resist.
Lombard's building inspector will request footing details if masonry is involved and may request proof of post depth (photos during construction) for wood fences in full-review scenarios. Some homeowners avoid the hassle by hiring a licensed fence contractor who guarantees frost-compliant installation; the contractor typically carries liability insurance that covers frost-heave failure. If you DIY, keep construction photos of footing depth and backfill; they're your defense against post-construction citations.
Corner lots, sight-line triangles, and why Lombard enforces these strictly
Lombard's zoning ordinance (verify via city website or call 630-620-7456 for the current chapter number) includes a sight-distance standard for corner lots. The rule is simple: at any intersection, a sight triangle must be maintained from the point of intersection outward 20 feet along both streets (forming a triangle). No fence, shrub, building, or structure taller than 3.5 feet can occupy that triangle. The purpose is traffic safety — a driver turning from one street onto another must see oncoming traffic. This rule is enforced in Lombard more strictly than in some neighboring suburbs because Lombard has had traffic-safety complaints and wants to avoid liability.
If you own a corner lot and want to install a fence within the sight triangle, you have three options: (1) Build it under 3.5 feet (a short fence, often aesthetically undesirable). (2) Relocate the fence outside the triangle (further back on your property). (3) Request a sight-line variance from the Zoning Board of Appeals (takes 4-6 weeks and is not guaranteed). Most homeowners choose option 2: move the fence back 25-30 feet from the corner, which is outside the critical sight zone. Lombard's building department will advise you of the sight-line requirement when you call or file; always ask if your property is a corner lot before ordering materials.
Neighbor complaints are a common trigger for sight-line enforcement. If your corner-lot fence obstructs a neighbor's view or a driver complains about visibility at the intersection, Lombard code enforcement will cite you, inspect, and issue a correction order. Removal or relocation is mandatory; the city will not grandfather non-compliant fences. Variance requests are rarely granted unless you can show that the sight triangle was already non-compliant before your fence (e.g., a large tree from before the fence ordinance was in place). Build to code the first time — a 3.5-foot fence or relocated 6-foot fence — to avoid a costly redo.

Common questions
Do I need a permit to replace my existing fence with the same height and material?
Likely no, if it's under 6 feet and in a side or rear yard. Lombard treats like-for-like replacement as a maintenance activity exempt from permitting, provided you match the original height and location. However, if your original fence was non-compliant (over 6 feet, in front yard, or a masonry wall), the replacement does not inherit the exemption — you'll need a permit to bring it to current code. Call the Building Department with your property address and describe the original fence; they can confirm exemption status in minutes.
Can I pull a fence permit myself, or do I need a contractor?
Illinois allows owner-builder permits for owner-occupied residential properties. Lombard permits the homeowner to file the permit application directly, provided the property is your primary residence. You do not need a licensed contractor to pull the permit or construct the fence. However, if you hire a contractor, they often handle the permit filing as part of their service, which simplifies the process. Either way, you are responsible for code compliance and inspection success.
How long does a Lombard fence permit take?
Over-the-counter residential fence permits (under 6 feet, non-masonry, rear/side yard) can be approved same-day or within 1-2 business days if your site plan is clear. Full-review permits (corner lots, masonry, pool barriers) take 5-7 business days for plan review, then you can begin construction. Post-construction inspections (final, or footing + final for masonry) are scheduled within 3-5 business days of your call. Total timeline from filing to certificate of compliance: 2-3 weeks for standard residential fences, 4-6 weeks if HOA approval is required or if plan revisions are needed.
What if my fence is built and the inspector says it's non-compliant?
Corrective action is required. If the fence exceeds height, violates a sight-line restriction, or has inadequate footing, you will be issued a correction notice with a timeline (usually 10-30 days) to remedy. Remedies include cutting down the fence, relocating it, deepening footings, or full removal and rebuild. If you ignore the correction notice, Lombard code enforcement escalates to fines ($250–$500 per day of non-compliance) and potentially forced removal at city expense, charged to your property tax bill. Correct non-compliance immediately to avoid compounding costs.
Are there any Lombard neighborhoods where fence rules are different?
Historic districts and planned communities within Lombard may have additional restrictions. Check your deed and call the Building Department with your property address to confirm whether your property is in an overlay district (historic district, wetland protection zone, or planned community with stricter fence guidelines). These overlays can require architect review, material approval, or color restrictions on top of the standard height and setback rules. HOA communities almost always have CC&Rs with stricter fence rules; these are separate from city code and must be satisfied independently.
My fence abuts a utility easement. Do I need utility company approval?
Yes, likely. If your fence sits within a recorded easement (water main, gas line, electric, sewer, drainage), you need written approval from the utility company or municipality before building. The utility company may require specific materials, height limits, or access provisions for future maintenance. Lombard's building department will ask if your property has easements; check your deed or survey. Comcast, Nicor Gas (ComEd's Illinois subsidiary), or Lombard Public Works will issue easement letters if your proposed fence is compatible with their infrastructure. Budget 2-3 weeks for utility approval; some companies allow fencing over easements, others prohibit it entirely.
What's the difference between a fence and a retaining wall in Lombard?
A fence is a barrier structure without structural load (it doesn't hold back soil). A retaining wall is a structural wall designed to hold back earth on a slope. In Lombard, a retaining wall is classified as a grading or drainage improvement, triggering a full permit even if it's under 4 feet. A purely aesthetic boundary wall on level ground (no grade change) may be permit-exempt if it's under 4 feet. If your property has a slope or you're filling behind the wall, it's a retaining wall and requires a permit, footing detail, and likely engineer review. When in doubt, call the Building Department with photos and your survey — they can clarify the classification in minutes.
Do I need an engineer or architect stamp for my fence permit?
For wood, vinyl, and chain-link fences under 6 feet: no. For masonry fences over 4 feet or for retaining walls: yes, recommended (and sometimes required). Lombard accepts hand-drawn site plans and footing sketches for standard residential fences, but a stamped structural engineer's drawing ($300–$500) eliminates risk of plan rejection and shows the inspector you're serious about code compliance. For pool barriers, a stamped gate specification is recommended if the gate is custom-built; pre-fabricated commercial gates with manufacturer certification can substitute.
If I build a fence without a permit and later want to sell my house, what do I disclose?
Illinois requires seller disclosure of unpermitted structures. If your fence was built without a permit and is visible (obvious to an inspector or buyer's realtor), you must disclose it. Buyers often demand removal or a retroactive permit before closing. Retroactive permits in Lombard cost 1.5-2x the original permit fee and require inspection to confirm code compliance — a fence built 5 years ago without a permit may be non-compliant by current standards and require rework. Disclosure is easier to manage if you obtained the permit upfront. If you didn't, budget $200–$400 for retroactive permitting and potential remediation at resale time.
Can I install a fence within my HOA community without HOA approval?
No. HOA CC&Rs are binding private covenants, separate from city code. Even if a fence is permit-exempt under Lombard code, it still must comply with HOA rules. The HOA can sue you for non-compliance, fine you, or require removal. Worse, some mortgage lenders will not finance a property with CC&R violations, which blocks resale. Always obtain written HOA approval before pulling a city permit or building. Most HOA approvals take 2-4 weeks (request expedited review if possible). Lombard's building department is aware of this requirement and may ask for HOA approval documentation when you file a permit in a deed-restricted community.
