Common Questions About Arborist Reports
Not sure what you need? Here are answers to the questions we hear most often.

Do I need an arborist report for HOA approval?
Most HOAs require one before approving tree removal. This is especially true for large or protected trees. Our report gives your HOA the professional justification it needs to say yes.
How long does it take to get an arborist report?
Most reports are ready within 3–5 business days after our site visit. Need it faster? Ask about rush delivery. Large or complex jobs may take 7–10 days.
Are your arborists certified?
Yes. All our reports are written by ISA Certified Arborists. ISA stands for the International Society of Arboriculture. Our certification number is included in every report.
Can arborist reports help with insurance claims?
Yes. Our reports document the tree's condition before and after damage. They show what caused the problem and what needs to be done. Insurance companies use this to process your claim.
How long does an arborist report take to complete?
The timeline has two parts: the site visit and the written report. We typically schedule the on-site inspection within 1–3 business days of your call. The written report is then delivered within 3–5 business days after that visit for most standard assessments — so plan on roughly one week from first contact to receiving your document. Complex jobs involving multiple trees, construction impact assessments, or disputed legal matters may take 7–10 business days as they require more detailed analysis and supporting documentation. If you're on a tight deadline — an HOA hearing, a permit application, or an escrow closing — let us know upfront and we'll do our best to accommodate a faster turnaround. Rush delivery is available for time-sensitive situations. Call (818) 717-8787 to discuss your timeline.

Types of Arborist Reports We Provide
Our ISA Certified Arborists prepare reports for a wide range of needs across Ventura and LA County. Tree Risk Assessments evaluate structural integrity and failure potential using standardized ISA protocols — these are the reports that quantify hazard level and are accepted by courts, insurers, and municipalities. Construction Impact Reports document tree conditions before grading or building begins and specify protection measures for trees within the construction zone; they're required on many Ventura County building permits.
HOA Compliance Reports provide the professional justification HOAs require before approving tree removal requests, especially for larger or protected trees on common lots or within easements. Insurance Claim Documentation establishes causation and pre-existing conditions — essential when a tree damages a structure and the insurer needs independent professional analysis. Real Estate Transaction Reports give buyers and sellers a clear picture of tree health, liability exposure, and recommended maintenance before closing escrow — increasingly requested in hillside and wildland-interface properties throughout Simi Valley, Thousand Oaks, and Calabasas.
All reports are signed by an ISA Certified Arborist, include supporting photographs and measurements, and are formatted for submission to LADBS, planning departments, HOA boards, and insurance adjusters. Call (818) 717-8787 to discuss which report type fits your situation.
