Title 14 — ZONINGChapter 14.64 — DUAL OPPORTUNITY DEVELOPMENTS (SB9)

§ 14.95

Los Altos Zoning Code · 2026-06 edition · updated 2026-07-08 · Los Altos

14.95.010 - Authority for Adoption.

This chapter is adopted pursuant to California Government Code Sections 50280 through 50290, commonly known as the "Mills Act."

(Ord. No. 2025-539, § 1, 10-14-2025)

14.95.020 - Purpose and applicability.

State law provides that the city council may contract with the owner of any qualified historical property in a manner which they deem as reasonable to carry out the purposes of the Mills Act. The Mills Act enables the city council, in its discretion, to enter into historic property preservation contracts with the owner(s) of qualified historical properties within the City of Los Altos. The historic property contract allows the owner of a qualified historical property to obtain preferential property tax assessment in exchange for restrictions on the property to help preserve, restore, and maintain the historic property.

(Ord. No. 2025-539, § 1, 10-14-2025)

14.95.030 - Definitions.

The following definitions shall apply for the purposes of this chapter:

"Anniversary date" means the date of final execution by all parties of the historic property contract and the same date each subsequent year that the historic property contract is in effect.

"Historic property preservation contract" means a contract between the owner(s) of a qualified historic property and the City of Los Altos, meeting all requirements of State law and this chapter. The "historic property preservation contract" may also be referred to in this chapter as "historic contract."

"Owner" means all persons and entities that have a right, title, or interest in the property which is the subject of the historic property contract. The term "owner" includes agents authorized in writing by the owner to act on owner's behalf. The term "owner" also includes owner's successors-in-interest.

"Qualified historical property" means a privately owned property, inclusive of the qualified historical improvements and any land on which the qualified historical improvements are located, which is not exempt from property taxation and which meets any one of the following criteria:

1.

A property or structure listed individually in the National Register of Historic Places;

2.

A property or structure listed individually in the California Register of Historical Resources;

3.

A property or structure listed individually in the City of Los Altos' adopted Historical Resource Inventory;

(Ord. No. 2025-539, § 1, 10-14-2025)

14.95.040 - Limitations on historic property contracts.

A.

The city council may, in its sole discretion and pursuant to the terms of this chapter, enter into historic contracts with the owners of qualified historical properties that are located within the City of Los Altos.

B.

Only qualified historical properties shall be eligible to enter into historical contracts.

C.

Applications for historic contracts must be received prior to July 1 of any calendar year to be processed during that calendar year. Historic property contracts must be approved, signed, and recorded in the Office of the Recorder of the County of Santa Clara on or before December 31 of a calendar year to be eligible for property tax reassessment for the following fiscal year.

D.

The intent of this chapter is to establish procedures whereby property subject to a historic property contract approved, executed, and recorded pursuant to this chapter will be eligible for property tax valuation as an enforceable restricted historical property pursuant to state law (Sections 439 through 439.4 of the California Revenue and Taxation Code, as may be periodically amended). In the event that only a portion of a property or structure is the subject of a historic contract, only that portion of the property or structure covered by the historic property contract shall be considered for preferential property tax assessment treatment under state law. The rest of the property or structure shall be subject to standard property tax assessment, and the total assessed value shall be a combination of the two methods as determined by the county assessor. This section shall not be construed to circumvent or diminish any requirements of the Subdivision Map Act.

E.

Properties with recorded historic contracts must comply with all applicable City of Los Altos rules, regulations, policies, permit requirements, and associated fees, including those needed to carry out the provisions of the historic contract. Entry into a historic contract does not relieve the property which is the subject of the contract from compliance with any and all applicable federal and state laws and local regulations.

F.

Applications for historic contracts on properties on which a notice of violation has been recorded will not be accepted under this chapter until the violation has been cleared.
