Bonita real estate agent for buying, selling, and ADUs.
I’m Zach, a real estate broker at Utmost. I’ve personally closed $201 million in home sales across 267 transactions, I work with Bonita buyers and sellers, from homes along the Sweetwater River valley to properties on larger hillside lots, and I help owners plan ADUs here too.

Zach's track record
The Bonita housing market
In September 2026, the median home in 91902 sold for $1,072,185, down 1.4% from a year earlier. Homes sold in a median of 29 days, for 100.0% of list price on average, and 31 homes sold, compared with 34 a year before.
If you’re selling
Prices are about even with last year, and homes are selling for full list price on average. Homes priced from the right nearby sales are selling in about four weeks, while homes priced too high tend to sit.
If you’re buying
Bonita offers single-family homes on larger lots, from streets along the Sweetwater River valley to hillside and horse properties. Fewer homes come up here than in nearby Chula Vista, so get pre-approved and be ready when the right one does.
If you own and want more income
Many Bonita lots have room for a detached ADU, a garage conversion, or a JADU inside the home. Septic, slope, and fire access are the details to check on larger lots before you design.

Adding an ADU in Bonita
Most of Bonita is unincorporated, so ADUs follow the County of San Diego’s rules. Here is what shapes most projects.
- How many: a single-family lot can usually add one ADU and one JADU of up to 500 square feet inside the home.
- Size and setbacks: a detached ADU can be up to 1,200 square feet, with 4-foot side and rear setbacks. Fire setbacks can be stricter on hillside lots.
- Septic and slope: some larger Bonita lots use septic, and the County’s environmental health team needs to confirm the system can handle the added unit. Hillside lots need a closer look at access and grading.
- City or County: some 91902 addresses are inside Chula Vista city limits, where the City of Chula Vista’s rules apply instead, so confirm your jurisdiction first.
- Rules change, so confirm details with the County of San Diego before you design.
What clients say
“The process of selling our home was incredibly smooth and not stressful one bit because of Zach! Our house was only on the market for 4 days and we got $50,000 over asking!”
“This was our 3rd time selling a home and Zach was the best agent we've ever worked with. He has a dialed in process, he's organized and he's data driven.”
“We were told not to expect a “deal”—just to get in the market and start building equity. But Zach found us a steal.”

Homes in 91902 sold in a median of 29 days in September 2026. Most sellers spend another two to three weeks getting ready to list, and escrow usually takes about 30 days after an offer is accepted.
Can I build an ADU on my Bonita property?
Most single-family lots in Bonita can add a detached ADU of up to 1,200 square feet and a JADU of up to 500 square feet, under County of San Diego rules. Septic, slope, and whether your address is in the county or Chula Vista are the details to check first.

Mostly no. Bonita is largely an unincorporated community under the County of San Diego, but some homes with a Bonita address and 91902 ZIP are inside Chula Vista city limits. The jurisdiction matters for permits, ADUs, and some fees.
