Santa Clara County Landlord-Tenant Law: Renting in the Capital of the Global Technology Economy
There is no rental market in the United States quite like Santa Clara County. The concentration of wealth, talent, and corporate infrastructure that has accumulated in Silicon Valley over the past six decades has produced a housing economy that operates by rules that apply nowhere else. Base salaries of $200,000 are not unusual. Signing bonuses that exceed a year’s rent in most American cities are standard. RSU vesting schedules create sudden influxes of income that bear no relationship to the monthly income figures that standard rental applications are designed to capture. And yet — despite all of this wealth — Santa Clara County has a severe housing shortage that keeps vacancy rates near zero in the most desirable neighborhoods and pushes workers without tech-company compensation into communities 40 or 50 miles away. For landlords, this market is simultaneously the most lucrative and most legally demanding in California after Los Angeles.
The legal complexity stems from the same dynamic that makes the market so lucrative: competition so intense that tenant protections have become a political priority, and cities have responded with local ordinances that layer on top of state law in ways that require constant attention. San Jose, the county seat and California’s third-largest city, operates its own Apartment Rent Ordinance. Mountain View, home to Google’s headquarters, has enacted one of the most tenant-protective rent stabilization ordinances in California. The rest of the county is governed by AB 1482. Navigating this patchwork correctly — for every property, before every action — is the central legal task for Santa Clara County landlords.
San Jose’s Apartment Rent Ordinance: The Largest Covered Inventory in the County
San Jose is the most populous city in the Bay Area and the tenth most populous in the United States, with roughly one million residents. Its rental market encompasses everything from luxury high-rises in Santana Row and the downtown core to aging pre-war apartment buildings in the Willow Glen and Berryessa neighborhoods. The city’s Apartment Rent Ordinance covers most rental units in buildings with three or more units that were built on or before September 7, 1979. The ARO sets allowable annual rent increases, establishes a petition process for landlords seeking above-guideline increases (for capital improvements, increased operating costs, or fair return), and requires just cause for eviction of all covered tenants.
San Jose landlords with covered units must register them with the city’s Rent Stabilization Program and pay annual registration fees. Failure to register does not eliminate rent stabilization obligations — it just adds penalties. The City of San Jose’s Rent Stabilization Program maintains an online lookup tool where landlords can verify whether a specific unit is covered and check the property’s registration status. Using this tool before every rent increase or termination notice is not optional for the well-managed San Jose portfolio.
The just cause requirements under the ARO are more expansive than AB 1482’s baseline. San Jose landlords cannot simply invoke AB 1482’s just cause provisions for ARO-covered units — they must comply with the ARO’s specific grounds, procedures, and timelines. No-fault evictions under the ARO require relocation assistance at levels that exceed AB 1482 minimums, calculated based on the tenant’s length of tenancy and other factors. A termination notice for an ARO-covered unit that fails to comply with the ARO’s specific requirements is void, regardless of whether it would otherwise be valid under state law.
Mountain View’s CSFRA: The Bay Area’s Toughest Local Ordinance
Mountain View passed the Community Stabilization and Fair Rent Act by ballot initiative in November 2016, and it has been in effect since early 2017. The CSFRA is notable for several reasons that distinguish it from most California rent ordinances. First, its coverage extends to rental units built on or before February 1, 1995 — a significantly later cutoff than either San Jose’s 1979 date or LA’s RSO 1978 date, meaning a large share of Mountain View’s rental inventory is covered. Second, rent increases under the CSFRA are not pegged to a fixed percentage; instead, they are governed by a fair return standard administered by the city’s Rental Housing Committee, which evaluates whether a proposed increase allows the landlord a fair return on investment. Third, the CSFRA requires just cause for eviction of all covered tenants, with relocation assistance obligations for no-fault terminations that are calculated based on length of tenancy and can be substantial.
For a landlord with a pre-1995 multifamily unit in Mountain View, operating under the CSFRA means registering the unit, paying registration fees, filing annual reports with the Rental Housing Committee, and complying with a rent increase process that requires a formal petition rather than simply providing notice. The administrative burden is real and ongoing. Mountain View landlords who are not actively engaged with the CSFRA compliance process face meaningful penalty risk. The Rental Housing Committee is actively administered and has demonstrated a willingness to enforce its ordinance against non-compliant landlords.
The tech company geography is worth keeping in mind when thinking about Mountain View’s rental market. Google’s Googleplex headquarters complex sprawls across a large portion of the northern Mountain View waterfront, and the company employs tens of thousands of workers who live in or near Mountain View. Google has been one of the most vocal advocates for housing construction in the region and has made significant financial contributions to local housing initiatives. This creates a political environment in Mountain View that has consistently supported strong tenant protections. The CSFRA is not going away, and it is likely to be strengthened rather than weakened in future election cycles.
For the majority of Santa Clara County that sits outside San Jose and Mountain View, AB 1482 is the operative framework. The CPI used for the rent cap calculation is the BLS CPI-U for the San Jose–Sunnyvale–Santa Clara metropolitan statistical area, which has historically tracked somewhat higher than the Inland Empire index given the Bay Area’s stronger inflationary environment. Sunnyvale, Santa Clara, Cupertino, and Milpitas — all home to major tech campuses — have no local rent control and are fully governed by state law. New construction in these cities is booming, driven by tech company demand and city upzoning efforts, and most of that new stock will be AB 1482-exempt for the first 15 years.
The security deposit cap change effective July 1, 2024 deserves specific attention in the Santa Clara County context. When one month’s rent on a Cupertino two-bedroom apartment can be $4,500 or more, a one-month security deposit cap means the landlord’s financial cushion against damage or default is limited to that same amount. Small landlords who meet the qualifying criteria — natural persons or LLCs with all-natural members, no more than two properties, no more than four total units — can still charge up to two months’ rent, but this exception does not apply to service member tenants. The practical implication is that thorough move-in documentation, pre-move-out inspection procedures, and prompt deposit accounting are more important than ever in this market.

The applicable CPI for AB 1482 calculations is the BLS CPI-U for the San Jose–Sunnyvale–Santa Clara MSA. Unlawful detainer actions are filed in Santa Clara County Superior Court, 191 N. First St, San Jose, CA 95113. Security deposit cap: 1 month’s rent (Civil Code § 1950.5; effective July 1, 2024). Deposit return: 21 calendar days. AB 1482 rent cap: 5%+CPI, max 10% per 12-month period; expires January 1, 2030. San Jose ARO and Mountain View CSFRA impose stricter requirements on covered units.
