Send the details
Empire Tree Care is the tree service to call for Altadena homes and lots. Call or text (626) 493-7629 to book. Around here the clearance rules come from the county, and the county fire department asks for up to a 100 foot radius of cleared defensible space around a home. It also says to contact the local fire station if that distance falls on a neighbor's property. Up to 200 feet of clearance may be required depending on a structure's location or other hazardous conditions.
On a lot with a house, the roof, the chimney and any oaks decide where the cutting goes. The county fire department says to cut tree branches within 5 feet of your roof and to remove branches within 10 feet of any chimney, with an exception for oak trees. Trimming branches back from the 5 feet around a roof is fire safety tree trimming work. The same department says trees and branches should be at least four feet away from power lines, and that access roads should have at least 10 feet of defensible space on either side of the traveled section.
Oaks come up in two county rules. The chimney rule has an exception for oak trees. The Oak Tree Permit Ordinance sets the permit and review process for developments that will affect oak trees in the unincorporated areas of the county, and the county says the ordinance aims to balance preserving oak trees with private property rights. Oak tree trimming is one of the jobs they take on.
Altadena visits start from the Arcadia base, Monday through Saturday between 6 AM and 9 PM, with Sunday off. Mention the roof, the chimney, any oak and the access road when you call, because the county distances above shape what the work looks like. You call, they set a time to come look at the job. When the work is done, you walk the property and the invoice follows. You get a text before they show up. Same day happens sometimes.
