Mendocino County panel approves withdrawn appeals and stipulations for Tesla and Main Street Capital

A Mendocino County assessment hearing approved the withdrawal of multiple appeals and accepted stipulations resolving protest cases involving Tesla Energy Operations and Main Street Capital Incorporated, officials said.

The actions came after staff described how assessable value was determined for photovoltaic systems and brewery equipment. Charlotte Scott, cutting counsel, advised the panel on procedure before discussion, and Nathan Maxman, senior auditor and appraiser in the Mendocino County Assessor's Office, explained valuation methods used for the contested properties.

The panel first heard and approved withdrawn protest application numbers 250001, 250002, 250003, 250004 and 250005. The clerk read the case numbers into the record before a member moved to approve the withdrawals and the board voted in favor with no abstentions or dissent recorded.

Officials then considered stipulations filed in place of appearance and testimony for several cases. The clerk read protest application number 220001 and purchase application number 230024 for Tesla Energy Operations; case numbers 240001, 240002, 240003 and 240004 for Main Street Capital Incorporated; and protest application number 240006 for Tesla Energy Operations Incorporated. After questions from board members, a motion to accept the stipulations was made and the panel voted to approve them.

Maxman said the assessor's office applied a new composite assessment factor for photovoltaic systems developed in conjunction with the California Assessors Association and industry stakeholders to better reflect market value for solar systems. "We use a composite factor that, has, index factor provided by the Bureau of Labor Statistics, and then it's also applied with a percent good that could that creates a composite assessment factor for it," Maxman said, summarizing the methodology. He also described that in the Tesla matter the contested items were treated as fixtures tied to the property and thereby assessable following a change of ownership.

Regarding Main Street Capital, Maxman said the assessor's office performed an audit using historic costs and reviewed taxpayer-provided purchase and 2024 sale information, as well as an outside appraisal of the business property, which resulted in a reduced assessed value. He described the brewery's assets as including tanks, bottling lines, forklifts and a tasting room.

Board members asked about the practical treatment of fixtures and equipment and how age and depreciation are applied. Maxman said industry changes, inflation, obsolescence and amortization are considered in the composite factor and percent-good calculations; he added colloquially, "Fixtures are clear as mud is how they describe them in, the course." Charlotte Scott advised the board to hold discussion before making a motion when questions arise.

The clerk noted there were no members of the public present in the chambers and no online hands for public comment. The board listed no requests for continuance or postponement and set the next meeting for Jan. 26.
