The first people living in the area now known as Cypress were the Gabrieleno, a Native American tribe of the Tongva people, who were displaced soon after the arrival of the Europeans. The government of Spain then possessed the land until Mexico gained its independence in 1821. Mexico then lost Alta California to the United States during the period following the Bear Flag Revolt and the Mexican–American War.
The original Spanish dons held immense tracts of land throughout California, which were given in lieu of pay to Spanish soldiers. Manuel Nieto was one of the early Spanish dons or landowners in the area. After his death in 1804, his sons retained title to Rancho Los Nietos, but these lands were eventually broken up and distributed among them in 1833 by a grant from the Mexican governor, José Figueroa. Manuel's son, Juan José Nieto, retained the title to a large portion of his father's original properties in southern California that included the present-day area of Cypress. That land and other Rancho properties were finally sold to the American Abel Stearns, then acquired by the Robinson Trust, a group of investors, which eventually parlayed their holdings into a vast land speculation business.
Cypress originally was nicknamed "Waterville" due to the preponderance of artesian wells in the area, but was incorporated under the name Dairy City in 1956 by local dairy farmers as a means of staving off developers and to preserve their dairies, much like the then-neighboring cities of Dairy Valley in Cerritos and Dairyland in La Palma. After World War II, however, the land became too valuable for farming or ranching, and the dairies gradually sold out to housing developers during the 1960s, so that by the 1970s no dairies remained. Many of the dairymen moved their operations to Chino, where development is once again pushing them out of the area.

Types of ADU
There are two types of ADUs - an ADU and a JADU. All residential lots can have one ADU and one JADU.
There are three kinds of ADU construction:
Detached: The unit is separated from the primary structure
Attached: The unit is attached to the primary structure
Converted Existing Space: Space (e.g., master bedroom, attached garage, storage area, or similar use, or an accessory structure) on the lot of the primary residence that is converted into an independent living unit
Junior Accessory Dwelling Unit (JADU): A specific type of conversion of existing space that is contained entirely within an existing or proposed single-family residence
Single-Family ADU Accessory Dwelling Unit Development Standards
ADUs are permitted in single-family residential zoned properties (R-1). All ADUs shall be constructed with independent access separate from the main residence entrance. All ADUs shall have a living/sleeping area, a kitchen or kitchenette (i.e., stove or hotplate, refrigerator, and sink), and a bathroom that includes a shower or bathtub. ADUs are no longer subject to Lot Coverage and Floor Area Ratios of the city's zoning designation. The following are single-family ADU development standards:
Detached Accessory Dwelling Unit
Maximum of two stories or 25 feet
ADU shall match the architectural design of the existing or proposed main dwelling.
Attached Accessory Dwelling Unit
Maximum of two stories or 25 feet
Cannot exceed 50% of the existing main dwelling unit
ADU shall match the architectural design of the existing or proposed main dwelling
Setbacks for your ADU
ADUs shall adhere to the state's setbacks of four feet from the side and rear yard and must remain 6 feet from the existing main dwelling. Existing accessory structures and single-family homes that are converted into ADUs are exempt from meeting the required setbacks however, any expansion shall meet the four-foot side and rear yard setback, as pursuant to Government Code Section 65852.2.
Parking for Tenant
All new ADUs will be required to provide one additional parking space, cover, or uncovered if the proposed ADU is not within a one-half (.5) mile radius of public transit station (bus stops included). However, for accessory structures or a portion of the existing residence that is converted into an ADU, no additional parking is required. An ADU cannot have direct access to a garage if the proposed or existing garage has less than three spaces.
Junior ADU Development Standards
Junior Accessory Dwelling Units (JADUs) are very small living units created within the existing main dwelling. The JADU must have a living/sleeping area, and a kitchen or kitchenette (i.e., stove or hotplate, refrigerator, and sink). A bathroom is not required, however, if a bathroom is not provided, the JADU shall have direct access into the existing main dwelling unit. A JADU cannot exceed a total of 500 square feet and any expansion of the existing main dwelling to accommodate the JADU shall not exceed 150 square feet.
JADUs shall adhere to the state's setbacks of four feet from the side and rear yard. Existing single-family homes that are converted into JADUs are exempt from meeting the required setbacks as pursuant to Government Code Section 65852.2.
Parking is not required for JADUs, however, an ADU cannot have direct access to a garage if the proposed or existing garage has less than three spaces.
Multi-Family Lots ADU Development Standards
ADUs are permitted on multi-family zoned properties (R-2 and R-3). All ADUs shall be constructed with independent access separate from the main residence entrance. All ADUs shall have a living/sleeping area, a kitchen or kitchenette (i.e., stove or hotplate, refrigerator, and sink), and a bathroom that includes a shower or bathtub.
