Is There a Flat Fee for an Oak Tree Permit in Unincorporated LA County?
No. Step outside Santa Clarita city limits into Stevenson Ranch, Castaic, Val Verde or Agua Dulce, and the oak tree permit stops being a number you can look up in advance. The city prices its permit on a published schedule. The county bills it as a deposit against actual staff and forester time, with no fixed total until the file closes. Buyers who budget the city's numbers for a county property are budgeting the wrong document.
Which oak trees are protected in unincorporated LA County?
The threshold is a trunk of 8 inches or more in diameter, measured four and a half feet above natural grade, anywhere in the unincorporated county. Inside a Significant Ecological Area or the Santa Monica Mountains zones, the threshold drops to 6 inches. A heritage oak is one of 36 inches or more in diameter, and every impact to a heritage oak requires a permit with a public hearing. This comes from the county's own Oak Tree Permit FAQ, version dated July 8, 2025, and matches the primary ordinance text at County Code Section 22.56.2060.A, now recodified as Chapter 22.174 in the current Municode index. Santa Clarita city limits use a different genus-based rule measured in circumference, not diameter, covered in the Santa Clarita oak tree permit guide.
Why two county documents disagree about the protected zone
This is the kind of detail that decides whether a pool plan needs a permit, and the county's own paperwork does not agree with itself. The primary county code text, Section 22.56.2060.C, defines the protected zone as the area from the dripline of an oak tree out to five feet beyond the dripline, or 15 feet from the trunk, whichever distance is greater. The current Oak Tree Permit FAQ repeats that "whichever is greater" language exactly. But the county's own oak tree permit checklist describes the same zone as five feet from the dripline and 15 feet from the trunk, "the more restrictive measurement shall apply," which reads as the smaller of the two, not the larger. The statute controls over a checklist form. Use "whichever is greater," and if a contractor's site plan was drawn to the smaller reading, have it checked against Section 22.56.2060.C before relying on it.
What the application has to include before the county will look at it
An oak tree permit application is not a one-page form. The county's checklist requires a scaled site plan showing every oak within 200 feet of the proposed work, each one tagged and numbered; an oak tree report from a certified consulting arborist covering trunk size, canopy spread, health and disease; a separate oak tree protection plan describing how remaining trees will be shielded during construction; at least six color photographs of the property and the work area; and a written analysis of alternative site designs showing the proposal is the least damaging option considered. Filing happens online through EPIC-LA, the county's permitting portal, and an incomplete submission is not accepted rather than flagged for follow-up.
Who actually decides: director, hearing officer, or commission?
Removing, pruning past the two-inch exemption, relocating, damaging or encroaching on a protected tree all require the same permit, but not the same process. Where no other permit or map is filed alongside it, and the work is a single tree tied to a permitted single-family use, the county does not require published notice of the filing at all, under Section 22.56.2130.C. Everything else gets a public hearing under Section 22.56.2160. The decision itself, per Sections 22.56.2170 and 22.56.2180, is made by "the hearing officer or the director or commission," and the county forester and fire warden's site inspection report feeds directly into that decision. Where the county forester decides on-site replacement is not practical, the applicant can be routed instead into paying the oak resource value of the tree into the county's oak forests special fund, money that by Section 22.56.2140.D can only go toward planting or maintaining oaks on public land or buying oak woodland, not general county revenue.
What happens if you disagree with the decision
A director's decision can be appealed to the Regional Planning Commission. Here the county's process is shorter than the city's. Under Section 22.56.2240.B, a commission decision on a standalone oak tree permit is final on the date it is made. It only reaches the Board of Supervisors when the oak tree permit was decided together with a separate permit, variance, zone change or subdivision map, and even then the oak question can only be appealed as part of that other entitlement, not on its own. Santa Clarita city limits work differently end to end: a director's decision there can go to the Planning Commission and then to the City Council, with each appeal priced on the city's own fee schedule.

Why the fee is not a number you can shop for in advance
Section 22.56.2110 ties the county's oak tree permit fee to the general fee schedule at Section 22.60.100, and the county's own 2026 filing fee schedule lists oak tree inspection and permit line items against a separate deposit table rather than a flat dollar figure next to each tier. In practice, that means the arborist report, the forester's site visit, the hearing preparation and any monitoring during construction are billed against a deposit, and the applicant is invoiced further if the deposit runs out before the file closes. Confirm the current deposit amount with LA County Planning's Current Planning Division at the time of filing rather than carrying a number forward from a past transaction.
What if a previous owner already cut a tree without a permit
Section 22.56.2260 treats every tree cut, damaged, removed or relocated in violation of the ordinance as a separate offense under the county's general penalty provisions. That liability does not require a permit to have been denied first: it attaches the moment the work happened without one. A buyer cannot rely on a seller's silence. Civil Code section 1102.8 states that the standard disclosure form "does not limit or abridge any obligation for disclosure created by any other provision of law," so a seller who knows about an unpermitted removal still has a problem, form box or no form box. Ask directly, in writing, whether any oak on the lot has been cut, pruned past the exempt size or encroached upon, and whether a permit was pulled.
Q: Does a single oak removed for a single-family home need a public hearing in unincorporated LA County?
Not automatically. Where it is one tree, tied to a use already permitted on a single-family lot, and no other application is filed alongside it, the county does not require published notice, which in practice means no public hearing under that narrow path.
Q: Can the Board of Supervisors overturn a Regional Planning Commission decision on an oak tree permit?
Only if the oak tree permit was decided together with another permit, variance, zone change or subdivision map. A standalone commission decision on an oak tree permit alone is final the day it is made.
Q: Is the 8-inch threshold about to change?
LA County Planning has been reviewing an update to the 1982 ordinance, with outreach meetings held through 2025 and a public draft not yet released as of this writing. Until the Board of Supervisors adopts a revision, the thresholds in this article remain the ones in effect.
Q: Do I need an EPIC-LA account just to check whether a past oak tree permit was ever issued?
The checklist directs new applications through EPIC-LA, but a records question about a specific address is a call to LA County Planning's Current Planning Division rather than a self-service lookup.
