When a tree becomes part of a permit, construction plan, or insurance requirement, the stakes change immediately. What was once a simple property feature becomes a regulated asset that must be properly documented before work can continue.
At Dario Tree Trimming, we provide a certified arborist report designed for these situations, where accuracy and compliance determine whether your project moves forward or gets delayed. Our reports support tree removal permits, construction approvals, insurance documentation, and municipal requirements across San Fernando Valley.
In many cities, tree work cannot proceed without a certified arborist report. Missing or poorly prepared documentation often leads to rejected permits, delays, costly revisions, and in some cases, can stop your project from moving forward entirely. Our process is built to eliminate that risk with clear, submission-ready reporting.
Tree issues are rarely obvious. Many develop internally, within roots, structure, or decay zones, long before visible symptoms appear.
As tree inspection experts, we conduct detailed on-site evaluations to determine actual tree condition and risk. Each inspection focuses on:
Site conditions affecting safety or compliance
This level of inspection is critical, where permit approval depends on accurate documentation and justification.
A certified arborist report is often required for permits involving protected trees or construction activity near root zones. In Sylmar and across neighboring cities, these reports are a standard requirement before approval is granted.
At Dario Tree Trimming, every report is prepared with municipal expectations in mind. We understand what city reviewers require and structure documentation accordingly.
These reports are commonly used for tree removal permits, construction projects, tree protection plans, insurance claims, and property evaluations.
With the growing demand for housing in Los Angeles, certified arborist reports are also commonly required for Senate Bill 9 (SB 9) projects, including lot splits and ADU (Accessory Dwelling Unit) developments. Proper documentation ensures these projects meet city requirements while addressing protected tree regulations.
Not all arborist reports meet the same standard. Some are general summaries, while others are built specifically for regulatory approval.
Our certified arborist reports are designed for outcomes—not just documentation. Each report is created to support decisions, reduce delays, and move projects forward.
What sets us apart:

Steven ClantonTrustindex verifies that the original source of the review is Google. Gave us a free estimate. Services included tree trimming on a very steep hillside, weed-eating, and total clean up. Our property is approximately 1 acre with over half at a 33 degree slope. We are now in total Fire Department regulations compliance. All of the crew were extremely polite. Dario and his sons are very careful regarding full explanations, gave written estimate of work to be done, and made sure we were happy with the progress throughout the job. The Dario Tree Trimming crew worked and completed the job beyond our expectations. We are thrilled to have done business with them. Fair price, fantastic work, nice people, clean job. We highly recommend them and will use their services next year to maintain our property. CRI PastineTrustindex verifies that the original source of the review is Google. I spoke to David and let him know what i needed. I have a large Ash tree on my front yard that was overgrown as well as a sidewalk tree that was hanging over the street. His crew took care of both trees and they even cleaned up my hill. I am so glad i found them. I highly recommend JohnnybeGoodTrustindex verifies that the original source of the review is Google. Dario Tree Trimming was great to work with. They are prompt and came out same day to provide a quick estimate and was well within our expected price range. For the work that needs to be done, they were able to come out the next day to do the service on time with a large crew who got the job done quickly and we are so happy with their work. Exceptional service and work. Highly recommended Art HerreraTrustindex verifies that the original source of the review is Google. Great job at a reasonable price.

Dario, David and their crew did an incredible job on our property removing trees and clearing a hillside. We’ve used them several times and will continue working with them! The whole process is fast and thorough and they do not leave a mess behind. If I could give them more stars ⭐️ I would! Dino MaglarasTrustindex verifies that the original source of the review is Google. I have been a longtime customer of Dario Tree Trimming. Due to the heavy rainfall we had, our massive tree was leaning dangerously to one side. Dario was able to come out and remove it the very same day I called them. I would highly recommend them for any landscape work that needs to be done. JiYoung OhTrustindex verifies that the original source of the review is Google. 2 thumbs up to Dario Tree Trimming! I have a 21,000 SF yard with numerous trees and shrubs that became overgrown and unsightly. After receiving several estimates, I chose this company because Domingo is a certified arborist who was incredibly thorough and professional during our initial walkthrough. His quote was also very reasonable. Domingo and his team were highly efficient and detail-oriented. They gave my yard a complete makeover, which included removing 7 trees, trimming and thinning Norfolk and Juniper trees, pruning fruit trees and trimming all hedges and shrubs. I was so impressed that I referred them to my sister, who has a larger yard with mature trees situated close to her house. It was a 2-day job involving significant tree removal and brush clearing to mitigate fire hazard, and Domingo gave us a great price. He and his father came with a team and once again, they did an amazing job. Beyond their expert work, they truly care about their customers and provide helpful maintenance tips. For example, Domingo pointed out that 3 Sumac trees near a wood fence were a fire hazard due to their high petroleum content and volunteered to remove them for free. This is a wonderful family-operated business that combines professional expertise with genuine care! Tamara DullTrustindex verifies that the original source of the review is Google. Dario Tree Trimming honestly exceeded my expectations. If all contractors were this professional, responsive, and polite, homeowners would be a lot happier. I reached out to several companies for estimates to trim three large ash trees. I heard back from Dario's team within a few hours. David came out, assessed everything, and gave us an on-the-spot estimate. The pricing was competitive and exactly in line with what I expected. We moved forward without hesitation. Dario stayed in touch via text, and scheduling was easy. On the day of service, the full crew arrived right at 7 AM and completed the job in about two and a half hours. They worked like a well-oiled machine - efficient, coordinated, and constantly cleaning up as they went. We opted for a shape-and-trim service, and the trees look fantastic. I already plan to have them back in the fall for our birch trees and then put everything on a two-year maintenance schedule. Highly recommend. Valerie RuizTrustindex verifies that the original source of the review is Google. Everything about my experience with Dario Tree Trimming was efficient and quick. I called for an estimate and Diego was on site within an hour; he fully explained the cost and the work which would be included. I decided at time of quote to go ahead and proceed with the work. Within 24 hours I was scheduled - for the next day! The crew showed up on time and was finished with the entire job, both front and back yards, in less than 2 hours. I was impressed the crew put up a large piece of plywood for protection against our window near the large tree in the front yard. They did a fantastic job on cleanup as well. All trees are trimmed to my satisfaction; shaped and balanced properly.
