Sonoma-Marin Tree Service connects Windsor homeowners with local tree service contractors for removals, oak pruning, fire clearance, and stump work. Much of Windsor's housing is from the last few decades, built around oaks that were here long before it, and those oaks are the trees that raise permit questions, drop limbs in storms, and fill the foothills with fuel in fire season.
Windsor protects its native trees
The Town of Windsor has a tree preservation ordinance that protects native species throughout town. When it was adopted, the protected list was ten natives: eight oak species, California buckeye, and California bay. Removing a protected tree takes a permit from the Town's Planning Department, and cutting or damaging one without a permit has carried civil penalties. The zoning code also allows emergency removal when a protected tree is an immediate threat to public safety.
We have not confirmed the current size thresholds, so do not assume a tree is too small to count. Call Windsor Planning before taking out any oak, buckeye, or bay. If the Town wants information on the tree's condition, arborist reports and tree permits explains what a report covers. Non-native yard trees, such as liquidambar, Chinese pistache, ornamental pear, and pines, are usually a simpler job, but check the Town's list first.
Oaks in Windsor yards
Many Windsor subdivisions were built with mature valley oaks and coast live oaks left in place in yards, along creeks, and on common ground. Those trees did not grow up with lawns, sprinklers, and driveways over their roots, and summer irrigation under an established oak can bring on root rot. The common jobs here are removing deadwood over roofs and patios, reducing heavy limbs that extend over a house, and, where an oak has failed or is failing, oak tree removal with the right permit.
Prune oaks lightly and at the right time. Heavy cuts stress an old valley oak, and the industry standard is to remove only what the tree can handle. tree trimming and pruning done to ANSI A300 standards keeps the tree's structure intact instead of topping it.
The Kincade Fire and the east-side foothills
The Kincade Fire in October 2019 forced the evacuation of Windsor and burned through the hills east and north of town. Since then, homes along the foothills toward Shiloh Ranch Regional Park have paid more attention to the trees and brush around them. Fire service in Windsor is provided by the Sonoma County Fire District, formed in 2019 in part from the former Windsor Fire Protection District.
Useful fire-season tree work here includes removing dead and fire-damaged trees near the house, limbing oaks up off the ground so a grass fire cannot climb into the canopy, cutting limbs back from roofs and chimneys, and thinning dense bay and brush on hillside lots. See defensible space and fire clearance for how that work is usually laid out from the house outward.
Storms, stumps, and access
Windsor's flat lots and wide streets make most removals easier than they are in the hills, but winter storms still bring down oaks with decayed roots and big limbs from trees that have not been pruned in years. After a removal, stump grinding takes the stump below grade so you can replant or lay sod. On foothill lots, steep driveways and narrow gates can limit equipment, so ask how the contractor plans to get the wood out.

Frequently asked questions
Do I need a permit to remove an oak tree in Windsor?
Very likely. The Town of Windsor protects its native oaks, along with California buckeye and California bay, and removing a protected tree requires a permit from the Planning Department. Confirm the current rules with Windsor Planning before any work, especially for a large tree.
Can I remove a dangerous oak in an emergency?
The Town allows emergency removal when a protected tree is an immediate threat to public safety or welfare. Take photos before and during the work, and contact Planning as soon as you can so the removal is on record.
Who is the fire agency for Windsor?
Windsor is served by the Sonoma County Fire District, which was formed in 2019 from several agencies including the former Windsor Fire Protection District. For questions about defensible space requirements on your property, contact the district.
When is the best time to prune oaks in Windsor?
Oaks are commonly pruned during the dry season or dormant winter months, avoiding heavy cuts during spring growth. More important than the month is how much is removed: light, structural pruning is far better for an old oak than large cuts.
