Around Lake Tahoe, two goals can feel like they pull against each other: thinning trees near your home for fire safety, and following the environmental rules that protect the lake. In practice, the system is built to make fire-safety work easy. Most of it needs no permit, and when one is required, your local fire district can usually issue it as part of a free inspection.
This guide walks through the tree rules most Tahoe Basin homeowners run into, from Incline Village to Zephyr Cove to South Lake Tahoe. Rules and phone numbers change, so confirm details with your fire agency before any cutting.
The 14-inch rule, in plain terms
The Tahoe Regional Planning Agency (TRPA) sets the basin-wide tree rules. In most cases, trees less than 14 inches in diameter can be removed without a tree removal permit. A permit is required to remove live trees greater than 14 inches diameter at breast height (DBH) as long as the house is not along the lakeshore. TRPA's April 2026 permitting manual still lists tree removal permits (required for trees over 14 inches) among its most common applications, so the threshold remains current.
How to measure. Diameter at breast height is measured 4.5 feet above ground on the uphill side of the tree. If unsure, a string or soft measuring tape around the trunk works. A 14-inch tree is 43.9 inches around. If your tape reads close to that number, stop and ask your fire district to look at it.
What you can usually do without a permit. According to the Tahoe Fire and Fuels Team, owners can remove and manage brush in the "lean, clean, and green" zone within 30 feet of structures, remove dead limbs, limbs within 10 feet of a chimney outlet, building or deck, and any live limbs in the lower one-third of the tree, and remove live trees less than 14 inches DBH.
When the rules get stricter
The 14-inch line is not universal. A few situations trigger a permit at smaller sizes, or for any size.
- Lakefront homes. If the house is along the lakeshore, a permit is required to remove trees greater than 6 inches DBH between the house and the lake. Trees not between the house and the lake only need a permit if they are live trees greater than 14 inches DBH.
- Permit-related trees. Trees of any size that were planted or retained as part of a permit, or that are in a Stream Environment Zone or backshore area, require a permit for removal. Any manipulation of live vegetation within those sensitive areas, including shrubs, requires TRPA review.
- Heavy limbing. A permit is required for removal of branches from the upper two-thirds of a tree's height unless the branch falls into a listed exception. Those exceptions include branches within 10 feet of a chimney outlet, building or deck, branches rubbing utility lines, and dead branches. Always talk to your power company before cutting near lines.
- Dead trees. Removing a dead tree that could fall on a house does not require a permit. A conifer counts as dead when it has no green needles, but a deciduous tree must be confirmed dead by a qualified forester.
If your lot is a mix of these (say, a lakefront parcel with a creek channel), the safe move is a call to your fire district before anyone starts a saw.
Who actually issues the permit
For most homeowners, the answer is your fire district, not TRPA directly. When homeowners get a free defensible space evaluation from their local fire agency, tree removal permits are usually included, and evaluators can issue tree permits on behalf of TRPA if needed. All Lake Tahoe fire protection agencies can permit hazard trees for removal through these free evaluations.
Incline Village and Crystal Bay. The North Lake Tahoe Fire Protection District handles inspections and chipping. It opened scheduling for 2026 on Monday, May 4. If you missed the spring rush, check the district's site for current availability.
Zephyr Cove, Stateline and Glenbrook. Tahoe Douglas Fire Protection District inspectors are certified to issue TRPA tree removal permits when removal is necessary for fire safety. Inspections are available year-round, weather permitting. The district says its evaluation documentation is consistent with Nevada law and acceptable to most homeowners' insurance companies. That is worth knowing, though your carrier decides what it will accept.
South Lake Tahoe. This one differs. The City of South Lake Tahoe does not conduct defensible tree permits, so you contact TRPA for tree removal inspections and permits there.
TRPA also says there is a streamlined path for legitimate hazard-tree removal, and it expects owners to use it.
Why skipping the process costs more
TRPA enforces these rules. In a July 2025 settlement, a homeowner on Alpine Drive in Incline Village paid $20,000 for removing two trees over 14 inches DBH that were not related to fire safety. The owner also had to plant four mature native conifers in TRPA-approved locations. The lesson is not to avoid cutting. It is to document the fire-safety reason through an inspection first.
The payoff for doing it right is real. After the 2007 Angora Fire, fire professionals reported that 75 percent of homes that survived in the burn area had completed some form of defensible space.
Where trees fit inside the defensible space zones
You rarely need to clear-cut anything. The Living With Fire guide describes Zone 0 as 0 to 5 feet from the home, Zone 1 as 5 to 30 feet, and Zone 2 as 30 to 100+ feet. For a deeper look at each zone, see our guide to defensible space zones (the zone numbers there match this framework).
For trees specifically, the guide's recommendations are about spacing and ladder fuels:
- Within 30 feet of the house, canopies of individual trees or small groups should be separated by 10 to 30 feet.
- Where trees are thinned, lower branches should be removed to at least 10 feet, and shrubs and trees under the drip line should be removed.
- Branch removal should not exceed one third of the tree's total height. Taking more can harm the tree.
- Remove needles and debris routinely within 5 feet, every spring from 5 to 30 feet, and keep litter under 3 inches deep beyond 30 feet.
South Lake Tahoe adds a local twist. City regulations require nothing combustible within 0 to 5 feet of a structure. Mature trees do not have to go: they are fine, though they may need limbing. The only trees the fire department may ask you to remove are dead ones.
What this means for your home
- Request a free inspection first. Ask your fire district for a defensible space evaluation before hiring a tree crew. It is usually the same visit that produces any TRPA permit you need. Homes in Incline Village and South Lake Tahoe fall under different agencies, so start with the right one.
- Handle the easy work yourself. Rake needles, move firewood away from the structure, and remove small brush and live trees under 14 inches, following the guidance above.
- Measure before you cut. Wrap a tape at 4.5 feet on the uphill side. Anything near 44 inches around gets a second opinion.
- Check for lakefront, creek and backshore conditions. These are the cases where smaller trees and shrubs can need review.
- Keep your paperwork. Save the inspection report and any permit. If you are shopping for coverage or renewing, ask your carrier what documentation it wants. Our overview of Nevada and Lake Tahoe insurance explains how this fits in, and your carrier sets final pricing.
- Plan construction with inspections in mind. On the north shore, a defensible space inspection is required for all projects requiring a Washoe County building permit, and all items noted must be corrected before permit closeout.
- Look for rebates. A recent Nevada Tahoe Conservation District program with Tahoe Douglas Fire offered reimbursement of up to 50% of completed defensible space work, with a maximum rebate of $5,000, in Upper Kingsbury, Zephyr Heights, Zephyr Cove, Zephyr Knolls and Marla Bay. Homeowners must first schedule an inspection through the fire district. Confirm that it is still open before you plan around it.
- Think about the house, too. Trees and brush are only half the picture. Embers find gaps in vents, gutters and siding, and a free home hardening assessment can show you what to fix inside the first 5 feet. If you add roofing or exterior finishes on a home visible from the lake, TRPA suggests you consult its planners on the reflective qualities of the material.

Frequently asked questions
Can I cut down any tree under 14 inches at Lake Tahoe without a permit?
In most cases, yes. TRPA says live trees under 14 inches DBH can generally be removed without a tree permit. Exceptions include lakefront trees between the house and the lake (6 inches), trees in Stream Environment Zones or backshore areas, and trees planted or retained under an earlier permit. Check with your fire district if any of these might apply.
Do I need a permit to remove a dead tree near my house?
TRPA says removing a dead tree that could fall on a house does not require a permit. A conifer is considered dead when it has no green needles. A deciduous tree must be confirmed dead by a qualified forester. For a dead tree away from the house, TRPA says to contact one of its foresters to find out whether a permit is needed.
Who do I call for a defensible space inspection?
Call your local fire district. On the north shore of Nevada, that is North Lake Tahoe Fire Protection District. At Zephyr Cove, Stateline and Glenbrook, it is Tahoe Douglas Fire Protection District, at 775-588-3591. In South Lake Tahoe, the city fire department runs defensible space inspections, but contact TRPA for tree removal permits. Fire agencies' policies and schedules can change, so confirm before you book.
