San Francisco Is Building ADUs Everywhere. The Fencing Has Not Caught Up.
Walk through the Outer Sunset on a Tuesday morning and count the construction dumpsters. Better yet, try Bernal Heights, where it feels like every other lot has a new accessory dwelling unit going up in the backyard. San Francisco approved a record number of ADU permits in recent years, and the pace is only increasing. The city wants density. Homeowners want rental income. Everyone wants more housing.
Here is what nobody talks about until they are standing in a half-finished backyard: you need a fence. Not just any fence. You need something that separates the primary residence from the ADU, gives tenants privacy without making the yard feel like a prison exercise yard, and survives the relentless combination of salt air and fog that rolls in from Ocean Beach every single evening.
That is exactly where hog wire fence earns its spot. It is open enough to keep sightlines and natural light flowing between units, strong enough to handle San Francisco's year-round coastal wind, and built from materials that do not rot, warp, or develop a mold problem every winter.
Why Hog Wire Outperforms Everything Else in SF's Climate
San Francisco's marine fog, salt air, and constant wind create one of the harshest coastal fence environments in California. Here is how the three most common materials stack up.
| Factor | Hog Wire (Galvanized / Dip-Coated Metal) | Wood (Cedar / Redwood) | Vinyl |
|---|---|---|---|
| Salt Air Resistance | Excellent (galvanized and coated steel) | Poor (accelerates rot and graying) | Moderate (resists rust but yellows and becomes brittle) |
| Fog and Moisture Tolerance | Excellent (no absorption, no mold) | Poor (constant moisture causes mold, mildew, warping) | Good (does not absorb, but mold sits on surface) |
| Wind Load | Excellent (open mesh lets wind pass through) | High resistance creates stress on posts | High resistance; panels can crack or detach |
| Lifespan in SF Climate | 30 to 40-plus years | 8 to 15 years (with regular maintenance) | 15 to 20 years |
| Maintenance | Virtually none | Stain and seal every 2 to 3 years | Periodic cleaning, eventual replacement |
| Aesthetic in Garden Settings | Modern, clean, supports climbing plants | Classic but degrades visually | Looks suburban, not SF |
That wind load row deserves a second look. Solid panel fences act like sails. In neighborhoods like the Richmond or Parkside, where gusts routinely hit 25 to 30 mph, a solid wood or vinyl fence puts enormous lateral force on your posts. Hog wire's open mesh grid lets wind pass right through. Your posts stay upright. Your fence stays standing.
The ADU Angle: Why Hog Wire Is Perfect for Multi-Unit Properties
When you are carving a property into separate living spaces, you need fencing that does a few things at once. It needs to define boundaries clearly, so both your tenant and your family have that. It needs to preserve natural light in what are often compact San Francisco lots. And it needs to look intentional, not like an afterthought bolted on after the ADU inspection.
Black Hog Wire Fence Panels from BarrierBoss nail all three. The black dip-coating gives a clean, modern look that fits right into the design language of contemporary ADUs. Pair them with wood or metal posts and a top rail, and you have a fence that looks like your architect specified it.
Prefer something brighter? Silver Hog Wire Fence Panels have that raw galvanized steel aesthetic that works beautifully with climbing jasmine, bougainvillea, or whatever your garden calls for. Let the plants fill in over a season and you have a living wall with a steel backbone that will last four decades.
San Francisco Permit and Planning Rules You Should Know
If your fence is 6 feet or under, you generally do not need a building permit in San Francisco. The city's Planning Code (Article 7.50) kicks in for anything taller than that, and at that point you are dealing with the Department of Building Inspection plus potential planning review.
A few things to keep on your radar for 2026:
- Front Yard Setbacks: Fences in front yards are typically limited to 3 feet in residential districts. Hog wire at that height still looks great and keeps the sidewalk feel open, which planning likes.
- Historic Districts: If you are in a historic district (parts of the Mission, Pacific Heights, Alamo Square), exterior changes including fencing can trigger additional review. Check with SF Planning before you build.
- HOAs in Newer Developments: Condos and planned developments in places like Mission Bay, Dogpatch, and Hunters Point Shipyard often have CC&Rs that dictate fencing materials and heights. Get your HOA's written approval before ordering.
- ADU-Specific Requirements: Some ADU permits include conditions about screening and separation. Your approved plans may already specify a fence. Read them before you order.
What Hog Wire Fence Actually Costs in San Francisco
San Francisco is expensive. You already knew that. But hog wire fence is one of the more budget-friendly options, especially when you factor in the decades of zero maintenance ahead of you.
Materials
BarrierBoss panels are priced factory-direct with no distributor markup. For a typical 150-linear-foot residential project (common for a standard SF lot with an ADU), you are looking at roughly $1,500 to $3,500 in panel costs depending on height, style, and post configuration. Browse the full collection of hog wire fence panels for current pricing.
Labor
Local fence installation labor in San Francisco runs $60 to $100 per hour in 2026. A straightforward hog wire install for that 150-foot run typically takes a two-person crew 1.5 to 2.5 days, depending on terrain and soil conditions. Some Bernal Heights hillsides require more post engineering than a flat Sunset District lot. Budget $1,400 to $3,500 for labor.
Total Installed Cost
All in, most San Francisco hog wire fence projects land between $3,000 and $7,000. Compare that to a wood fence that costs nearly the same upfront but needs staining every few years and replacement in a decade, and the math gets clear fast.

Frequently Asked Questions: Hog Wire Fence in San Francisco
Will the Salt Air From the Pacific Corrode Hog Wire Fence Panels Over Time?
Galvanized steel with dip-coating is specifically engineered to resist salt-air corrosion. BarrierBoss panels are built with this exact environment in mind, and our 40-year warranty backs that confidence. Wood, by contrast, starts showing salt damage within a few years in neighborhoods like the Outer Richmond and Sunset where marine exposure is heaviest.
Can I Use Hog Wire Fencing to Separate My Primary Home From My ADU and Still Pass SF Inspection?
Yes. Hog wire fence meets code requirements for property delineation and screening between dwelling units, as long as it complies with height limits and any conditions written into your ADU permit. Keep it at or under 6 feet and you will not trigger a separate fence permit. Always cross-reference your approved ADU plans for any specific screening conditions.
My Lot in Bernal Heights Is on a Steep Slope. Does Hog Wire Work on Hills?
Hog wire is actually one of the best fencing types for sloped terrain. Panels can be stair-stepped or racked to follow the grade, and the open mesh design means you are not fighting water runoff or soil pressure the way you would with a solid panel. An experienced installer will know how to set post depths for hillside stability. Need one? Find a local fence installer through our network.
Do SF Planning Restrictions Limit Me to Certain Fencing Materials in Residential Neighborhoods?
San Francisco's residential design guidelines do not generally mandate specific fencing materials outside of historic districts and planned developments with HOAs. Metal hog wire is widely accepted and increasingly popular in neighborhoods across the city. If you are in a historically designated area or an HOA community, get written confirmation of approved materials before purchasing.
