AfterFast, Reliable Fence Installation Across Tamalpais Valley
Fence installation in Tamalpais Valley typically runs $3,500 to $9,000 for a standard residential project, and the quote you get depends heavily on one thing most contractors won’t mention up front: whether your fence sits within 5 feet of your house. If it does, and it almost always does on the smaller post-WWII lots along Shoreline Highway, Marin County will require ignition-resistant materials that meet CBC Chapter 7A. We’re Barrett & Sons Construction, and we’ve been navigating those rules since 1998. Call (877) 610-1318 and we’ll walk you through what your specific lot actually requires before you spend a dollar.
Tamalpais Valley is not Mill Valley. It’s an unincorporated Marin County pocket at the base of Mount Tamalpais inside a Cal Fire Very High Fire Hazard Severity Zone, and the permit process reflects that. A fence that’s perfectly legal across the city line can fail inspection here. That’s why we write every material spec, every permit requirement, and every dollar into a written change order before the first post hole goes in. No surprise invoices at the end. Tom Barrett puts his name and license number on every contract, and he answers his own phone.
Why Barrett & Sons Construction Is Tamalpais Valley’s Preferred Fence Installation Company
We’re not a franchise dispatching strangers from three counties away. Tom Barrett founded this company in 1998, and his sons run the crews. When you hire us for fence installation in Tamalpais Valley, the person who shakes your hand at the estimate is the same person who shows up on install day. The same person who answers if something’s wrong at month two. The 90-Day Done Right Promise is written on every contract, not buried in fine print: if it’s not done right, Tom comes back and makes it right, one call.
Our reputation in Tamalpais Valley comes from the way we handle the unincorporated paperwork. Marin County Community Development Agency permit reviews are widely regarded as among the slowest and most environmentally restrictive in California. A simple fence permit can take 6 to 8 weeks. We submit a complete scope of work, a documented draw schedule, and a site plan the first time, because we’ve learned what the reviewers flag and what they pass. That’s why Tamalpais Valley homeowners who’ve been burned by other contractors end up calling us for the re-do.
We publish our license number. We publish Tom Barrett’s name. We publish our address. Look us up before you sign anything. Every crew member is background-checked and uniformed. Every permit gets pulled and every inspection gets signed. The permit inspector works for you, not for me, and that’s exactly how we treat him.
Our Fence Installation Services in Tamalpais Valley
Aluminum Fence
Aluminum is the workhorse for Tamalpais Valley lots inside the 5-foot noncombustible zone. An aluminum fence installation in Tamalpais Valley runs $4,000 to $10,000 depending on linear footage and gate count. Powder-coated aluminum carries no organic material, so it clears CBC Chapter 7A without argument. It also holds up to the marine fog that rolls off Mount Tamalpais and accelerates rust on untreated steel. We spec thicker-gauge posts than the box-store panels, because winter winds here will lean a flimsy post in one season.
Vinyl Fence
Vinyl is the practical choice for homeowners who want the privacy of wood without the rot. Vinyl fence installation in Tamalpais Valley runs $3,500 to $9,000. The fog and the 50-plus inches of winter rain in wet years mean wooden posts soaking in saturated soil will eventually fail. Vinyl doesn’t absorb water. For fences more than 5 feet from the structure, vinyl is fully code-compliant and needs almost no maintenance. For fences within 5 feet of the house, we pair vinyl panels with a fiber-cement infill or steel post frame to satisfy Chapter 7A.
Wood Fence
Redwood and cedar are the traditional Marin County look, and we still install plenty of both in Tamalpais Valley. The catch is the fire code. Untreated cedar or redwood pickets inside the defensible-space zone are a code violation in the VHFHSZ, and a Marin County inspector will flag it and refuse to sign off until it’s rebuilt with steel or fiber-cement. We use ignition-resistant treated wood when wood is what the homeowner wants within 5 feet of the structure. That product costs more, which is why a cheap quote that omits it looks great until the inspection fails.
Fence Gates
Gates are where fence installations in Tamalpais Valley go wrong. A 6-foot privacy fence with a sagging gate was either hung on lightweight hinges or built without a proper post footer. We pour every gate post to depth per code and use adjustable steel hinges so the gate swings true a year later. Automated driveway gates need a separate electrical permit through the county, and we pull that with the fence permit so the whole job clears at once.

Trusted Brands We Service in Tamalpais Valley
When a fence job in Tamalpais Valley touches another part of the property, homeowners sometimes want a matching upgrade. We carry GAF roofing products when a fence re-route exposes flashing issues, and Grohe fixtures when a fence gate install leads to an outdoor shower or garden sink. More to the point for this page: we stock aluminum and vinyl panel inventory locally so Tamalpais Valley customers aren’t waiting on a supply truck from the East Bay. If a panel arrives damaged or a gate section was measured wrong, we can make it right within days, not weeks. The material brands we install have published specs you can look up, not mystery products off the back of a van.
Common Fence Installation Problems We See in Tamalpais Valley Homes
- Noncombustible requirement missed within 5 feet of the house. Marin County inspectors will flag a standard wood fence in the defensible-space zone and refuse to sign until it’s rebuilt with steel or fiber-cement. The homeowner eats the demo cost and the re-inspection fee. We spec materials that pass the first time.
- Grading and biotic triggers on canyon lots. The hillside canyons off the Shoreline Highway corridor feature steep, irregular lots where trenching for a post line within 100 feet of the wildland interface can trigger a separate county grading permit and a biotic assessment. That’s a multi-agency approval process that can stall a project for months. We check the trigger distance during the estimate.
- Post rot from persistent marine fog and heavy winter rain. Tamalpais Valley gets substantially more precipitation than San Francisco or the East Bay. Wooden posts set directly in saturated soil without proper gravel drainage or concrete collars fail early. We set posts with drainage and use steel-reinforced post bases on every wood fence.
- Insurance claim gaps from missing documentation. If a wildfire hits and your fence was built without Chapter 7A compliance documentation, your insurer can deny the claim. We provide a compliance record with every inspection sign-off, from post hole depth to final gate swing.

What moves the number: linear footage, how much of the fence line falls inside the 5-foot noncombustible zone, whether your lot triggers a grading or biotic review, and gate count. A cheap quote that leaves out the Chapter 7A materials, the site plan, or the permit will fail inspection. We don’t do that. Call (877) 610-1318 for a free estimate with a written line-item scope.

FAQs - Fence Installation in Tamalpais Valley
Yes, if any part of the fence sits within 5 feet of a structure. Tamalpais Valley is inside a Cal Fire Very High Fire Hazard Severity Zone, so Marin County enforces CBC Chapter 7A. Fence sections within 5 feet of the house must use noncombustible materials like steel or fiber-cement, or ignition-resistant treated wood. Standard untreated redwood or cedar pickets in that zone will fail inspection. Call (877) 610-1318 for a free estimate and we’ll flag exactly which sections of your fence line fall under the rule.
A fence permit through the Marin County Community Development Agency is required for most replacements over a given height, and the review typically takes 6 to 8 weeks. Your project may also need a site plan showing the fence line in relation to the 100-foot wildland-interface grading trigger. We pull every permit and we don’t treat them as optional. Call (877) 610-1318 and we’ll tell you which permits your specific lot triggers.
Yes. If your post-line trenching falls within 100 feet of the wildland interface, the county can require a separate grading permit and a biotic assessment before the fence permit clears. This is common on the steeper canyon lots above the Shoreline Highway corridor. We check the trigger distance during the free estimate so you’re not blindsided mid-project. Call (877) 610-1318 to schedule your estimate.
A fence installed to CBC Chapter 7A with documented inspection sign-offs gives you a compliance record to submit to your insurer. If a wildfire damages your property and your fence was built without that documentation, the insurer can deny the claim. We hand you a complete record at the end of the job, from post hole depth to final gate swing. Call (877) 610-1318 for a free estimate that includes the documentation.
Expect 6 to 8 weeks for Marin County CDA permit review, plus 2 to 5 days of on-site installation for a standard residential fence. A big canyon-lot job with grading or biotic triggers can stretch longer. We give you a written schedule with the estimate so you know exactly when each step happens. Call (877) 610-1318 and we’ll map out a timeline for your specific lot.
On a Shoreline Highway post-WWII lot, we installed a 6-foot redwood privacy fence with a steel post-and-rail frame and fiber-cement infill to meet Chapter 7A. The Marin County Community Development Agency required a site plan showing the fence line outside the 100-foot wildland-interface grading trigger, and our crew documented every inspection sign-off, from post hole depth to final gate swing, so the homeowner could submit the compliance record to their insurer. That’s the standard we hold on every fence job in Tamalpais Valley. Call (877) 610-1318 to schedule your free estimate, and ask for the written scope of work before you sign anything. We’ll put it on paper.
