Bonita is not a city. It is an unincorporated community in the Sweetwater Valley, run by the County of San Diego, and the Census Bureau counted 12,917 people there in 2020. Much of it uses ZIP code 91902. The County's plan describes mostly low-density single-family land, with parks and open space along the Sweetwater River. Before you make an offer, check the exact address: County or Chula Vista, which agencies serve it, its school districts, flood and fire zones, the airport notice, and any special tax.

| Topic | What the official record shows |
|---|---|
| Status | An unincorporated community, listed by the Census Bureau as Bonita CDP (Census-designated place). In unincorporated areas the County provides services such as law enforcement, roads, parks and building permits. |
| Planning area | Bonita sits in the County's Sweetwater Community Plan area, part of the County General Plan. The plan was last amended in 2014. It covers about 8,000 acres of unincorporated land south of State Route 54 and east of Interstate 805, north of Chula Vista. The Census place is smaller, about 5 square miles of land, so the two outlines differ. |
| Neighbors | The plan says Chula Vista borders the area on the west and south, Spring Valley on the east, and National City and the City of San Diego on the north. |
| Population | 12,917 at the 2020 Census. |
| ZIP code | Much of Bonita uses 91902. Some nearby addresses use the Chula Vista ZIP code 91910. |
| City line | The plan says a large section of the valley along Bonita Road has been annexed to Chula Vista. A home on Bonita Road can be in the City, not the County, so confirm the jurisdiction of each address. |
| Water | Sweetwater Authority serves Bonita. The plan says the Otay Water District serves the eastern part of the plan area. |
| Fire and ambulance | The Bonita-Sunnyside Fire Protection District, a special district, serves the community. Ambulance transport is through a partnership with the Chula Vista Fire Department. |
| Law enforcement | The San Diego County Sheriff. |
The County plan calls the area mainly low-density single-family. In the western half, it says, most of the land is developed with single-family homes on parcels under an acre, with little commercial land and no industrial land. It also describes a semi-rural area with hiking and riding trails, and it names Bonita Woods and Bonita Highlands as separate neighborhoods. The river valley is used for parks, golf courses and open space.
Each check below depends on the exact address. A free property report pre-checks fire, flood and fault zones for any San Diego County address.
Because part of Bonita Road was annexed, one street can have County and City parcels. Permit, ADU and short-term rental rules follow whichever agency covers the parcel, so ask before you rely on a rule.
FEMA maps flood hazard areas in part of Bonita, mainly the Sweetwater River valley. The plan says floodway zoning prohibits or severely restricts grading, filling and construction. Look up the address on the FEMA Flood Map Service Center.
Bonita is Local Responsibility Area land, not State Responsibility Area, on CAL FIRE's maps. Most of the community is mapped non-wildland. Some hillside and valley-edge land is mapped Moderate or High, and a small area is Very High. Check the address on the State Fire Marshal's zone map.
Nearly all of Bonita lies in the Review Area 2 outer ring of the airport influence area for NAS North Island, and a small part falls in San Diego International Airport's Review Area 2. Sellers must give a Notice of Airport in Vicinity. This is a disclosure step only.
A special tax can show up on a property tax bill. The County Auditor's FY 2025-2026 list has no district named for Bonita. It does list school-district and City of Chula Vista districts, but not which parcels pay them. Read the current tax bill through the San Diego County Treasurer-Tax Collector; it lists each assessment with the charging agency's phone number. School districts post lookups for Chula Vista Elementary and Sweetwater Union High.
Some Bonita neighborhoods are common interest developments. For a resale home in a homeowners association, California Civil Code 4525 requires the owner to give you the governing documents and an assessment statement. Read them before your contingencies end.
On unincorporated land, ADUs follow County rules, and on March 4, 2026 the County adopted a program for the separate sale of ADUs through a condominium conversion process, with eligibility rules. Chula Vista parcels follow City rules. Check the County ADU page before you plan one.
Most of Bonita is in the Chula Vista Elementary School District for the lower grades and the Sweetwater Union High School District for the upper grades. A few edges of the area touch other districts. This page does not rate or rank schools.

State Route 54 and Interstate 805 bound the plan area on the north and west. Bonita Road runs through the valley. For transit, MTS bus Route 705 (E Street Transit Center to Plaza Bonita) has stops on Bonita Road at Andorra Way and Plaza Bonita Road. Plaza Bonita mall is in National City. Routes change, so check sdmts.com for the current schedule.
If you own in Bonita, several checks above become part of your disclosure package: the Natural Hazard Disclosure report, the airport notice, HOA documents and any special-tax notice. Confirm early whether your parcel is County or Chula Vista, since that decides which office handles permits.

Neither. Bonita is an unincorporated community, which the Census Bureau lists as Bonita CDP (a Census-designated place). It has no city government, so the County of San Diego handles services such as law enforcement, roads, parks and building permits. Part of the valley along Bonita Road has been annexed to Chula Vista, so check the jurisdiction of each address.
Much of Bonita uses ZIP code 91902. Some nearby addresses use a Chula Vista ZIP code, 91910, so a Bonita-area address does not always carry a 91902 ZIP. ZIP codes are mail routes, not jurisdiction lines, so check the address itself.
Sweetwater Authority provides water to Bonita, and the County's community plan says the Otay Water District serves the eastern part of the plan area. Fire protection comes from the Bonita-Sunnyside Fire Protection District, a special district, and ambulance transport is through a partnership with the Chula Vista Fire Department. Law enforcement is provided by the San Diego County Sheriff. Confirm by address.
Most of Bonita is in the Chula Vista Elementary School District for the lower grades and the Sweetwater Union High School District for the upper grades. A few edges of the area touch other districts. Assignment depends on the exact address, so use each district's lookup tool and confirm with the district.
It can. The County Auditor's FY 2025-2026 list has no district named for Bonita, but Chula Vista Elementary, Sweetwater High and City of Chula Vista districts appear on it, and which parcels pay which one is not on the list. A special tax can appear on a tax bill, so check the home's current property tax bill and the seller's disclosures.
Use the FEMA Flood Map Service Center and CAL FIRE's Fire Hazard Severity Zone map, and read the seller's Natural Hazard Disclosure report for the specific home. Part of Bonita, mainly along the Sweetwater River valley, is in a FEMA flood zone, and some hillside and valley-edge land is in a mapped fire zone. The free property report on this site also pre-checks these zones for any San Diego County address.
