Saratoga’s Updated Tree Rules and the 5-Foot Zone Around Your House

Most homeowners I talk to in the Saratoga foothills have no idea the rules changed. On March 6, 2026, an update to the city’s tree regulations took effect, and it changes what you are allowed to do with trees sitting right up against your house.

The city ties the update to state fire safety standards, lessons from recent wildfires, and the growing problem of homeowners struggling to keep property insurance. That last one is the reason my phone rings. People get a letter from their carrier first, and then they call about a tree.

So here is what actually changed, what the five-foot zone means in practice, where there is money available to help, and why a rule that allows removal is still not a reason to remove a healthy tree.

What Changed in Saratoga’s Tree Rules on March 6, 2026

The headline piece is this: homeowners citywide may now remove trees located within five feet of the home to reduce wildfire risk. That applies across Saratoga, not just in the hills.

But it comes with a condition, and the condition is the whole point. You have to establish and then keep a non-flammable zone in that same five feet. Take the tree out and let dry brush, bark mulch, or stacked firewood fill the space back in, and you have missed what the rule was written for.

A few things worth being clear about:

• This is a narrow, condition-based allowance, not blanket permission to clear a yard
• It is tied to the five feet closest to the structure, measured from the house
• The non-flammable zone is an ongoing maintenance obligation, not a one-time job
• Trees outside that five-foot band are still handled under the city’s normal tree rules

The city documents the allowance, along with the other changes discussed below, on its own official Saratoga tree regulations page. I tell homeowners to read it before they call anyone, because knowing which category your tree falls into changes the entire conversation.

The Wildland Urban Interface Piece, in Plain Terms

This is where most of the confusion lives. Saratoga is one of six Santa Clara County communities with zones CAL FIRE designates Very High Fire Hazard Severity, and the city treats those Wildland Urban Interface areas differently.

In WUI-designated areas, Saratoga has reduced tree replacement requirements for development projects. The reasoning is to limit ladder fuels.

If you have never heard the phrase, ladder fuels are exactly what they sound like. Low brush and low limbs give a ground fire a ladder to climb into the canopy. Once fire is in the canopy, it moves fast and it moves high.

Here is the part homeowners rarely hear: you can usually break that ladder without taking the whole tree out. In the field, that looks like:

• Limbing up, raising the lowest limbs so there is vertical separation from the brush below
• Selective thinning to reduce fuel density in the canopy
• Deadwood removal, because dead material burns readily
• Canopy spacing between neighboring trees so fire cannot bridge from one crown to the next
• Clearing the brush layer underneath, which is often the real problem

A mature Coast Live Oak with six feet of clearance under it and no brush beneath is a very different fire situation than the same tree with dry chaparral crowded around the trunk.

There Is Cost Share Money, and It Has Limits

The Santa Clara County FireSafe Council manages a Saratoga hazardous tree removal cost share program. It reimburses 50 percent of project costs, up to $1,000 per parcel, for dead tree removal in the WUI.

Walk through what that means in practice, because the details matter:

• It is a reimbursement, so you pay for the work and then submit for your share
• It is capped at $1,000 per parcel, no matter how large the project is
• It applies to dead trees. A live but stressed tree is a different conversation entirely
• Funding is first come, first served, so availability changes through the year

I will not quote you a removal price here, and you should be skeptical of anyone who does over the phone. Cost swings widely with trunk size, access, and how close the tree sits to the house, fence, or power lines. A 40-foot dead pine in an open side yard and a 40-foot dead pine wedged between a roofline and a neighbor’s pool are not the same job.

If you want to understand what drives a number before you get one, we broke that down in detail in what goes into the price of tree trimming. The short version: get an assessment, then talk about money.

What Gets Weighed Before Anyone Recommends Removal

This is the three-part evaluation I run through on every fire-driven call, before a saw comes out.

A Rule That Permits Removal Is Not a Reason to Remove

This is the section where I have to be direct. Every time a fire rule loosens, I get calls from homeowners who have already decided the tree is coming down.

Proper assessment before action still applies. A good evaluation weighs whether the tree is structurally compromised or simply struggling, where it sits relative to the house and the power lines, and what a mature canopy is worth to that property over the next twenty years. In Saratoga and Los Gatos, a healthy mature tree is often carrying real value in shade, cooling, and curb appeal.

Two warnings I give every single time:

• Never top a tree for fire safety. Cutting the trunk or major limbs back to stubs forces weak, fast-growing shoots that are far more likely to fail in winter wind. It trades a fire concern for a storm hazard
• California oaks should generally only be pruned between July and October in this climate. They go dormant in summer, and wet-season cuts invite moisture-loving pathogens

When a tree has a genuine weak point rather than a fire problem, there are middle options. Cabling and bracing can support a split or weak fork in cases where removal would otherwise be the default answer. And if you are dealing with oaks specifically, oaks in Saratoga, Cupertino, and Almaden play by different rules than the rest of the trees in your yard.

The Saratoga Change Stops at the City Limit

Homeowners assume rules travel across town lines. They do not. Here is roughly how the neighboring jurisdictions differ.

When the Insurance Letter Comes First

The quiet reason many of these calls happen is not the city at all. It is a carrier letter.

One caller told us their insurance company was threatening to cancel over trees overhanging the house. I hear a version of that regularly from homeowners in Saratoga and Los Gatos, and almost all of them assume removal is the only acceptable answer.

Often it is not. What frequently satisfies a carrier is:

• Clearance pruning to get limbs off the roof and away from the structure
• Deadwood removal throughout the canopy
• Documented defensible space work in the zones closest to the house

The piece homeowners miss is documentation. Having an arborist write down what was done and why gives you something concrete to send back to the carrier. A photo and an invoice for “tree trimming” is not the same as a written assessment describing clearance distances and canopy condition.

If you are earlier in the process and still deciding, read this before you remove a tree and, for the San Jose side of the line, the ordinance-size tree rule that triggers a permit.
