Glossary of Terms

- Annual General AdjustmentAnnual General Adjustment is the percentage by which rent may be increased each year in rent-stabilized apartments in Mountain View; this is part of CSFRA. It is equal to the Consumer Price Index of the San Francisco-Oakland-San Jose region. For the year beginning Sept 2017 was 3.4%. For the year beginning Sept. 2019 it is 3.5%. For the year beginning Sept 2020 it is 2.9%.

- Community Stabilization and Fair Rent ActThe Community Stabilization and Fair Rent Act (CSFRA) is the name given to the Charter Amendment (Measure V) passed by Mountain View voters in November 2016. An attempt to modify CSFRA, Measure D, was defeated by the voters in March 2020. Another ballot proposition to amend CSFRA is on the ballot for November 2020.
- Consumer Price IndexCPI or Consumer Price Index is data reflecting changes in prices paid for a representative basket of goods and services. CPI Housing only takes into account the changes in prices for housing.

- CSFRAThe Community Stabilization and Fair Rent Act (CSFRA) is the name given to the Charter Amendment (Measure V) passed by Mountain View voters in November 2016. An attempt to modify CSFRA, Measure D, was defeated by the voters in March 2020. Another ballot proposition to amend CSFRA is on the ballot for November 2020.
- Effective DateEffective Date of CSFRA is Dec. 23, 2016, the date Measure V was certified as approved by the voters, declared by the RHC on Sept. 11, 2017. Opponents had contended that the effective date was April 5, 2017, the date the court set aside the temporary injunction (sought by landlords/apartment owners) that prevented CSFRA from being enforced. It is important because the Base Rent is to be charged beginning on the effective date of CSFRA.
- EvictionEviction is the result of a court decision in an unlawful detainer case. An unlawful detainer case can be filed when there is just cause, or when there is no cause, except as modified by the Tenant Protection Act. In situations with no cause, the landlord needs to give the tenant a 30-day (or 60-day depending upon the length of the tenancy) notice to vacate without stating any cause or reason. If the tenant does not leave within that time, the landlord can then file an unlawful detainer, and, assuming the tenant has no legal defense, the court will order eviction of the tenant.
- Exempt UnitsExempt Units under CSFRA are units in hotels, motels, etc., rental units with government subsidies or tax credits, hospitals and extended care facilities, single-family homes and condominiums, duplexes, and companion units, also called accessory dwelling units, second dwelling units and granny units.
- Fair Rate of ReturnFair Rate of Return is a key term in rent-stabilization law as landlords may petition for an upward adjustment to the rent, above the Annual General Adjustment (AGA), if they can show that the AGA does not give them a fair rate of return. CSFRA excludes many factors that can be considered in determining a fair rate of return, but the decision of how to calculate a fair rate of return was left to the Rental Housing Committee (RHC). Fair rate of return per the RHC uses the maintenance of net operating income (MNOI) methodology. This method identifies the net operating income (NOI) in the Base Year (i.e., 2015 gross income from the property, less 2015 operating expenses.) The second step adjusts the NOI based upon the CPI-Rent of Primary Residence.
- Just CauseJust Cause for eviction means the Landlord has a good reason for terminating a tenancy, generally either failure to pay rent, or breach of the lease by the tenant. Reasons are stated in California Code of Civil Procedure and detailed in Dept. of Fair Employment and Housing definition. Tenants in all rental units (unless exempted as described above) with an initial certificate of occupancy before the Effective Date of CSFRA, 12/23/16, are subject to Just Cause protection. The Tenant Protection Act passed in 2019 has modified California law.
- Maintenance of Net Operating IncomeThe concept of Maintenance of Net Operating Income (MNOI) is the concept that the landlord was presumably receiving a fair rate of return in 2015, for example, and that the landlord should be able to maintain this NOI in the following years if they are to have a fair rate of return. This is a key part of rent-stabilization law.
- MNOIThe concept of Maintenance of Net Operating Income (MNOI) is the concept that the landlord was presumably receiving a fair rate of return in 2015, for example, and that the landlord should be able to maintain this NOI in the following years if they are to have a fair rate of return. This is a key part of rent-stabilization law.
- Net Operating IncomeNOI is net operating income. It is calculated by subtracting operating expenses from gross income.

- Partially exempt unitA partially exempt unit under CSFRA is a unit otherwise eligible that was issued a certificate of occupancy after Feb. 1, 1995. Partially exempt units are subject to just cause but not rent stabilization.
- Rental Housing CommitteeThe Rental Housing Committee per CSFRA shall consist of 5 Mountain View residents appointed by the City Council; no more than 2 members can own or manage rental property, or be realtors or developers.
- Rental Housing FeeRental Housing Fee is a fee to be charged all landlords governed by CSFRA on an annual basis. The fee may be different for those units that are partially exempt. The fee is set by the RHC and per CSFRA is to cover the costs of implementation of CSFRA.
- RHCThe Rental Housing Committee per CSFRA shall consist of 5 Mountain View residents appointed by the City Council; no more than 2 members can own or manage rental property, or be realtors or developers.
- Rollback dateRollback date is a CSFRA term referring to the date (Oct. 19, 2015) taken to calculate the Base Rent for current tenancies whose establishment predates the rollback date. It is called a “rollback” date because the CSFRA required upon its effective date that rents could not be higher than the Base Rent.
- Vacancy DecontrolVacancy Decontrol refers to the situation that occurs when a tenant voluntarily vacates a unit; the landlord can then charge whatever the market rent is at that time.
- Vega AdjustmentVega Adjustment addresses situations where the base year NOI was unusually low, typically because the rent charged for 1 or more units was unreasonably low. Vega refers to a court case which required such adjustments when using the MNOI methodology for fair rate of return. The RHC adopted a Vega Adjustment methodology which allows the landlord, as part of a petition for a fair rate of return, to identify units that were rented for less than the HUD Fair Market Rents (FMR) for Santa Clara County. The Vega Adjustment assumes that the rent charged for such units would be the higher HUD FMR rent, rather than the lower rent actually charged, thereby raising the gross income for the base year, which then affects the MNOI for the base year and allows an additional increase in rent for the year for which the landlord is petitioning. The increase in rent allowed would then be spread across all the units in the apartment complex that were subject to the Vega petition.
