Multifamily and Duplex Properties for Sale in Los Gatos: Zoning and Rent Rules

What multifamily in Los Gatos looks like

Los Gatos income property is mostly small and mid-size: duplexes and fourplexes near downtown, garden apartment complexes in the R-M zone along the flatter parts of town, mobile home parks in the RMH zone, and newer housing in the North 40 area. The hills to the south and west are low-density hillside zoning where added units usually mean ADUs. What sets the town apart is a local rental dispute ordinance with its own annual increase standard, which applies on top of state law. For two to four units, read financing 2-4 unit properties; for larger buildings, see apartment building loans.

Where the zoning allows it

Residential zones are in Article IV of Chapter 29 of the Town Code.

R-M density is set case by case. The rezoning ordinance assigns either the 5 to 12 or the 5 to 20 range, and the deciding body sets the exact density for each site when it issues the conditional use permit. Multifamily side yards are 10 feet, rising to 12 or 20 feet where windows face the side, and main buildings need 24 to 40 feet of separation. Ground-floor units need 120 square feet of private patio, upper units 60 square feet of balcony, and projects over four units need 100 square feet of community recreation space per unit, under open space rules last amended by Ordinance 2370 in 2025.

Hillside density. In HR, maximum units come from an average-slope formula, and above 50% slope the minimum land area is fixed at 5 to 160 acres per unit depending on the zone. Steep parcels usually support a single home and an ADU.

ADUs and SB 9. ADU rules are in Division 7 of Article I and SB 9 two-unit developments and urban lot splits in Division 10; we did not review their standards. See our ADU investment guide and SB 9 lot split guide.

Rent rules: the Los Gatos rental dispute ordinance and AB 1482

The Town’s rental dispute ordinance, Article VIII of Chapter 14, says it aims to prevent excessive rent increases while giving landlords a fair return. It was restated by Ordinance 2128 in 2004 and last amended by Ordinance 2320 in 2021.

• Coverage. It covers rental units except single houses, condominiums and planned development units, premises with only one dwelling, hotel stays under 30 days and a few other categories. Mobile homes owned by a park owner are included.
• Duplexes. Duplex tenants and landlords can use dispute resolution services and pay the per-unit fee, but duplexes are not eligible for mediation or arbitration, and the annual increase standard does not apply to them.
• The increase standard. Under Section 14.80.310, annual increases may not exceed the greater of 5% or 70% of the San Francisco-Oakland area CPI change unless an arbitrator finds a larger increase reasonable. Rent may rise only once a year.
• Pass-throughs. An increase of up to 5% plus pass-throughs of the town fee, capital improvements amortized over at least 60 months and documented rehabilitation over at least 36 months is presumed reasonable. Debt service increases can be passed through at 80%, limited to debt up to 70% of appraised value.
• Resets. The first increase after new construction, a voluntary vacancy or an eviction for cause is exempt, as is an increase of 10% or less when the last one was at least two years earlier.
• Notices. A rent increase notice is invalid unless it tells the tenant about the right to petition and names the Town’s agent. Evictions within 180 days of a tenant exercising rights are presumed retaliatory.

State law. The Attorney General’s rent cap page, updated July 16, 2026, puts Santa Clara County in All Other Counties, with covered units capped at 8.6% for increases starting August 1, 2026 through July 31, 2027. Its chart of local ordinances lists San Jose and Mountain View but not Los Gatos. Because the Town’s standard can be lower than the state cap, assume both apply and follow the stricter limit for a given unit, and have counsel confirm. AB 1482’s just-cause rules still matter for covered units. See our AB 1482 guide and just cause eviction guide.

Mobile homes. A separate Article VIII.V governs mobile home rents and disputes, with its own criteria for supplemental increases.

Los Gatos rental property rules

• No short-term rentals in apartments. Article XIV prohibits short-term rentals in all apartment complexes, below-market-price units and ADUs approved after February 6, 2018.
• License and caps. Where allowed, a host needs an annual license and a business license, must live in the home at least nine months a year, and is limited to 180 hosted or 30 unhosted nights a year. Licenses are capped at 5% of the town’s housing stock.
• Transfer tax. The Town’s real property transfer tax is 27.5 cents per $500, administered by the County Recorder; confirm how it combines with the County tax in escrow.

Older buildings, hillsides and seismic

The R-M zone was created with the Town’s 1976 zoning ordinance, and many older complexes predate current codes. Wood-frame buildings with tuck-under parking warrant a seismic retrofit review, and buildings of three or more units with elevated balconies or walkways need SB 721 inspections. Hillside properties face slope, fire and access limits that the HR zone ties directly to density.

Underwriting a Los Gatos multifamily purchase

1. Confirm the zone and, for R-M, the density range in the rezoning ordinance.
2. Determine whether each unit is covered by the Town’s dispute ordinance, AB 1482 or both.
3. Model annual increases at the lower of the Town standard (greater of 5% or 70% of CPI) and 8.6%.
4. Review past increase notices for the required petition language.
5. Collect leases, the rent roll and estoppel certificates.
6. Rebuild expenses with reassessed taxes, the Town fee, SB 721 and seismic costs in our rental property analysis.
