Pasadena Protected Trees: When You Need a Removal Permit
In Pasadena a coast live oak in the front yard of a single-family lot is a protected tree, and the same oak in the middle of the same back yard may not be. Species and size start the test. The part of the lot the trunk stands in finishes it.
Which trees are protected in Pasadena
Chapter 8.52 of the Pasadena Municipal Code, the City Trees and Tree Protection Ordinance, defines a protected tree at Section 8.52.020(T) as a native, specimen, landmark, landmark-eligible, mature (except in RS or RM-12 zones) or public tree.
| Category | Threshold | Where it is protected |
|---|---|---|
| Native | Trunk over 8 inches in diameter, 13 listed species | Yard areas in RS and RM-12, whole site elsewhere |
| Specimen | Species and size from the council-adopted list | Yard areas in RS and RM-12, whole site elsewhere |
| Landmark-eligible | Meets landmark criteria, not yet designated | Yard areas in RS and RM-12, whole site elsewhere |
| Landmark | Designated, no size test | Everywhere in the city, public and private |
| Mature | Diameter at breast height 19 inches or greater | All zones except properties under RS or RM-12 standards |
| Public | Any tree the city owns or controls | Everywhere, including the parkway strip |
The mature category is the one people misread. Section 8.52.085(F) reaches mature trees in any zone except projects subject to RS and RM-12 development standards, so a large non-native tree on an ordinary single-family lot is usually not covered. On a commercial lot, 19 inches makes it protected.
Pruning is where owners get caught, and the exemption is narrower than the rumors. Section 8.52.080(A) frees pruning only for a native or specimen tree on private property, and only where the tree is not injured. Section 8.52.085(A) requires a permit to prune a landmark tree anywhere in the city. Public trees are stricter still: Section 8.52.085(C) bars pruning one at all, and under Section 8.52.076 no permit for that goes to a private party. The parkway tree in front of your house is city work.
Why the spot on the lot decides it
Section 8.52.025(A) protects native and specimen trees in the established front yard, the required side yard, the established corner yard and the required rear yard of property in a single-family or RM-12 zone, and in all areas of every other zoning district. An established yard is the strip between the property line and the principal structure. A required yard is the setback your district imposes, which you read off the zoning code.
So a deep single-family lot has interior ground, behind the house and short of the required rear yard, where a native oak carries no protection. On a commercial lot that gap does not exist.
Section 8.52.020(J) stops that from becoming a loophole. It fixes a tree's location where any portion of the trunk sits at natural grade, and the city's Urban Forestry summary adds that if any portion of the tree is in the yard, the whole tree is protected. A trunk straddling the setback line is in.
How Pasadena measures a tree, and where the units change
Diameter at breast height is taken 4½ feet above ground on the uphill side of the trunk, under Section 8.52.020(C). On a sloping lot that moves the measuring point, so a downhill tape is not the city's number. The code also accepts circumference divided by 3.14.
Under Section 8.52.020(O) each trunk of a multi-trunk tree is measured at 4½ feet and the combined areas give the size. Combining cross-sectional areas produces a smaller figure than adding the tape readings, so do not sum the diameters.
The city's published Protected Species List runs to 129 entries, and the size column is not in one unit. For 121 entries the trigger is trunk diameter in inches, from 8 inches for the redbuds and camellia up to 30 inches for the two large figs and Raywood ash. For eight palms it is written in feet: 10 for Mexican blue, Guadalupe, pindo and Senegal date palms, 12 for king palm, 20 for Canary Island and true date palms, and 35 for California fan palm. The switch is not universal: European fan palm sits at 20 inches, Australian cabbage palm and Chinese fan palm at 15, all as diameter. Check which column your species is in before you reach for a tape.
The 13 native species sit at the bottom of that list at 8 inches, and the city publishes an illustrated native tree brochure for identification. Watch the walnut: plain black walnut, Juglans nigra, is a different tree on the same list at 25 inches.
When you need a permit and when you do not
Section 8.52.080 also frees work on a tree the chapter does not protect. The hazard exemption is the one people stretch. A protected tree can come out without a permit only where immediate action is required to protect life or property, and only after the city manager or a designee, a police officer or a firefighter has inspected it and found it hazardous. Dead in the owner's own judgement is not the test.
Everything else needs an application. Where no other discretionary approval is in play, Section 8.52.070(B) routes it to the city manager under the Chapter 17.60 procedures, and Section 8.52.075(B) gives the city 15 business days after a complete application to grant, deny or condition it. Appeals follow Chapter 17.72. Where the tree sits inside a project that already needs discretionary approval, the tree permit rides along and is decided by the same decision maker on the same day.
Relocation is separate. Section 8.52.077 sends it to the review authority and requires a bond equal to the full appraised value of the relocated trees, held until they are established for three years. Landmark trees cannot be relocated at all.
What the city has to find before it says yes
Section 8.52.075(A) starts from denial. A permit is refused unless the city makes one of six findings: an outweighing public or safety benefit, a tree unlikely to survive, an objective feature making it unsuitable for protection, substantial hardship to the owner, a refusal that would be a taking, or a landscape plan following the city's replacement matrix. The sixth is closed to landmark and landmark-eligible trees.
A developer relying on that sixth finding may request to pay a fee instead of planting up to half the replacement trees on site. Under Section 8.52.075(C) the fee is the full appraised value of the trees that cannot be replaced, capped at 50 percent of the appraised value of all trees to be removed, and further findings come first. Appraisals run on the current Guide for Plant Appraisal from the International Society of Arboriculture.
What protection costs during construction
Section 8.52.110 makes it a violation to leave a protected tree without sufficient guards during construction, and requires condition monitoring for three years afterward. Chain-link fencing goes up around the protection zone and is approved in place by staff before work starts, and work inside the zone is done with hand tools or an air spade. Fence height and the radius of that zone differ between the adopted guidelines and the Urban Forestry page. Settle both with staff.
What happens if a tree comes down without a permit
Section 8.52.155 makes a violation prosecutable as a misdemeanor or an infraction at the city prosecutor's option, and Section 8.52.160 sets the penalties. A misdemeanor carries up to a $1,000 fine and six months, and each day of a continuing violation can be charged as a separate infraction. Where the injury or removal is irreparable, the city may also sue for up to $5,000 per tree, or the full replacement value, whichever is higher. That phrase matters: $5,000 is a floor between two figures, not a ceiling. Section 8.52.160(E) adds a one-year freeze on building permits at the address.
What to check before you write the offer
- Pull the zoning district. RS and RM-12 change which categories apply.
- Walk the trunks, not the canopies. Location is fixed at the trunk.
- Measure at 4½ feet on the uphill side, and check whether your palm is scored by height or by diameter.
- Check the Protected Species List by species, not by genus.
Our protected tree pre-offer worksheet puts those checks on one page. Tree constraints belong with the rest of a buyer's due diligence, and the buyer page explains how that file gets built. Clearing a tree before listing is the wrong order of operations here, and the seller page covers what to settle first. Landmark designation is recorded with the county, so it also reaches the historic programs in our Mills Act comparison.
Neighboring cities differ. Santa Clarita measures oaks by circumference, Glendale runs a separate indigenous tree ordinance, and Burbank treats the parkway strip as city property.
Q: Do I need a permit to trim my oak in Pasadena? Not if it is a native or specimen tree on private property and the work does not injure it. A designated landmark tree needs a permit, and a street tree in the parkway is city work either way.
This is general information about a city ordinance, not legal advice. Code sections, fees and the protected species list change, and the city makes the determination on any individual tree.
