Preservation of Qualified Historical Property at 1830 Brown Street
LABEL
RECOMMENDED ACTION:
Recommendation
Approve and authorize the Community Resources and Development Director to execute the Mills Act Historic Preservation Agreement for the property at 1830 Brown Street.
Body
DISCUSSION:
The Applicant, Lauren C. Wesson Moskovitz, has submitted an application for a Mills Act Contract related to prior and ongoing preservation of a historic property, 1830 Brown Street, designated as Listed Resource (LR) on the City’s Historic Resources Inventory (HRI) with Contributing status in the St. John’s Potential Historic District.
The Mills Act Contract request for 1830 Brown Street does not propose improvements that require approval of a Certificate of Appropriateness at this time. Future exterior alterations may require additional review pursuant to the Historic Preservation Ordinance (NMC Chapter 15.52).
The Applicant proposes ongoing maintenance and repairs as reflected in the Ten-Year Rehabilitation Plan. In order to be considered eligible for the subsequent tax year assessment, a contract must be recorded at the County be the end of the calendar year.
SITE CONTEXT AND HISTORY
The Project Site is located on the east side of Brown Street between Yount Street and G Street within the RI 5, Residential Infill, zoning district and the Medium Density Residential General Plan Designation.
The subject property is listed on the City’s Historic Resources Inventory as a Listed Resource (LR) with Contributing status in the St. John’s Potential Historic District and has contributing status to the District. The home was originally constructed around 1925 and has been used for residential purposes since its construction, having been held in the same family for many years.
The home, described as ”rustic colonial,” was designed by local architect C.L. Hunt and built by local builder J. Henry Vienop. The property features a roughly rectangular plan with an intersecting gable roof, redwood clapboard siding, and six-over-one wood windows on the sides and rear. On the front façade a large picture window is flanked by two four-over-six windows and shutters, two additional four-over-two windows are located at the front porch. The entryway is covered by an arched pediment, a focal point of the home accessed by the raised front porch. Much of the home has been unaltered since its construction.
PROJECT DESCRIPTION
The City has received a request for approval of a Mills Act Contract on a property that has been restored. The Mills Act Contract is requested for the purpose of obtaining a property tax reduction to help offset the cost of repairs incurred in efforts to restore and preserve the subject historic building and for ongoing preservation of the building. No new work is proposed with this request. Proposed maintenance activities include:
• Repainting
• Foundation Improvements
• Landscape Improvements
• Re-roofing.
The full restoration plan is further described in the Ten-Year Rehabilitation Plan, attached as Exhibit C of Attachment 1, Mills Act Contract. The Applicant’s Project Description is included as Attachment 2, Project Description.
MILLS ACT OVERVIEW
The Mills Act was adopted by the State legislature in 1972. The Mills Act provides a means for an owner to reduce property taxes on a historic property in exchange for an agreement with a local government entity that the owners maintain the property’s historic character. The purpose is to encourage the renovation and maintenance of historic properties throughout the State by providing a tax incentive. It is similar to the Williamson Act, which encourages the preservation of agricultural land in return for a lower property tax rate.
The Mills Act enables local governments to enter into a voluntary contract with owners of historic properties. The City is not obliged to enter into a contract even if the properties are eligible. The contract extends for an initial term of 10 years. It will automatically renew each year on its anniversary date creating a new 10-year agreement unless the property owner or the City provides a notice of non-renewal. In such case, the contract will terminate at the end of the current 10-year term or the applicable renewal term. In order for a property to be eligible, it must be listed on the National Register of Historic Places, be listed on the California Register of Historic Places, or be listed on a local inventory. The subject property is eligible because it is listed on the City’s local Historic Resources Inventory.
The property owner must agree to restore (if necessary) and maintain the property in a manner appropriate to its historic character. The local government is responsible for monitoring the property to ensure that the owner performs the agreed restoration and/or maintenance. Many communities use the Secretary of Interior’s Standards for Rehabilitation as their restoration standard. However, each community makes its own determination as to what will be required of property owners.
Should the City determine the property owner has breached the terms of the contract, the City can bring legal action against the owner or simply cancel the contract. If the contract is cancelled for this reason, a penalty of 12.5% of the market value of the property at the time of cancellation is assessed. Although the contract is initially made between the existing property owner and the City, it remains with the property even after it is sold. When the property transfers, it is not reassessed at its new market value, thereby allowing the new property owners to enjoy a pre-existing reduced tax rate. This can contribute to the overall value of the historic property.
CULTURAL HERITAGE COMMISSION REVIEW
The Cultural Heritage Commission reviewed the Mills Act Contract request at their October 9, 2025, meeting. The Commission unanimously recommended that the City Council approve the Mills Act Contract.
FINANCIAL IMPACTS:
The recommended action would result in a reduction in the City’s share of annual tax revenue. The amount of property tax savings varies from year to year, based on expenditures for improvements by the owner. The City’s portion of property tax revenue also varies year to year. Current Tax Assessor information for the City’s active Mills Act Contracts is provided (see ATCH 3).
Because the initial term of the contract is ten years and the term is extended automatically each year for an additional year unless a notice of non-renewal is provided by the owner or the City, the reduction would continue for at least ten years. Once a notice of non-renewal is provided by the City or owner, the property tax reduction would cease upon the expiration of the remaining term of the contract.
The Napa County Assessor’s Office has provided tax information on 16 active Mills Act properties for 2025; eleven residential properties, four commercial properties, and one hospitality property. Based on information from the Napa County Tax Assessor Office, the total property tax savings for similar residential properties in 2025 is $133,974.18 for an average of $12,179.47.
The City’s portion of the property tax for FY25 is 5.68%. Based on current Tax Assessor data and the City’s property tax rate of 5.68%, the total property tax reduction for the City’s share of residential properties is $7,609.73 for an average of $691.79.
CEQA:
The Community Resources and Development Director has determined that the project is exempt from the requirements of the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Section 15301, which exempts minor alterations to an existing structure, and Section 15331, which exempts projects that rehabilitate, restore, preserve and conserve historical resources in a manner consistent with the Secretary of Interior’s Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring and Reconstructing Historic Buildings.
