What multifamily in King City looks like

King City’s zoning allows a wide range of small income property. Duplexes and triplexes are permitted outright in R-2, apartments and townhouses in R-3, and higher-density apartments in R-4, with ADUs allowed across the residential districts. Housing is also planned in the Downtown Addition Specific Plan, with mixed-use and live-work space near Broadway Street and the rail line, and the code has a separate chapter for seasonal employee housing tied to the farm economy. Two-to-four-unit buildings are the most common purchase; see financing 2-4 unit properties and, for larger buildings, apartment building loans.

Where the zoning allows it

King City’s residential districts date to Ordinance 354 in 1973, with amendments through 2026.

District	Multifamily rule	Key limits
R-2 Medium Density (Ch. 17.14)	Duplexes and triplexes permitted; two detached homes or condominiums by use permit	2,500 sq ft of site per unit; 6,000 sq ft lot (7,000 corner); 2 stories, 30 ft; 40% coverage
R-3 Medium High Density (Ch. 17.16)	Duplexes, triplexes, apartments and townhouses up to six units per building permitted; multi-building apartments and condominiums by use permit	2,000 sq ft per unit; 300 sq ft open area per unit; 2 stories, 30 ft; 60% coverage
R-4 Multiple Family and Offices (Ch. 17.18)	Apartments under 22 units per acre permitted; above 22 by use permit	1,575 sq ft per unit; 200 sq ft open area per unit; 2 stories, 30 ft; 60% coverage
C-1 Retail Business (Ch. 17.22)	Second-floor housing over commercial by permit	Residential area no larger than commercial area
Downtown Addition Specific Plan (SCH 2006041150)	Mixed residential and commercial districts	Up to 650 homes on about 110 acres under the approved plan

Minimum unit sizes. R-4 requires at least 480 square feet for a bachelor unit, 650 for one bedroom and 800 for two, plus 100 for each added bedroom. R-3 sets its own minimum floor areas. Undersized converted units will not meet code.

Two-story limit. Every residential district caps main buildings at two stories and 30 feet, so King City density comes from site coverage rather than height. The 22-unit-per-acre threshold in R-4 is effectively the by-right ceiling; anything above it needs a use permit.

Architectural review. In R-3 and R-4, development plans go to the city’s architectural committee before permits issue, and trash areas need a five-foot screen wall.

ADUs and two-unit developments. ADUs and JADUs are permitted in R-2, R-3 and R-4 under Chapter 17.47, and Chapter 17.80 covers second units and two-unit developments, the type of project state SB 9 allows on qualifying single-family lots. We did not read either chapter, so confirm sizes, parking and lot split rules with the city. See our ADU investment guide.

Inclusionary housing

Chapter 17.19, added by Ordinance 769 in 2019, applies to private projects of 20 or more units or residential lots. At least 2.5% of units must be affordable to very low income households and 5% to low income households, rounded up. Rents for low income rentals are capped at 30% of 60% of area median income, and restrictions run with the land for 55 years. A council-set in-lieu fee, paid into a housing trust fund before building permits, can substitute for on-site units. Smaller projects, including typical duplex-to-fourplex purchases, fall below the threshold.

Rent rules: state law only

Rent caps. The Attorney General’s rent cap page, updated July 16, 2026, puts Monterey County under All Other Counties: covered units may rise up to 7.7% for increases from August 1, 2025, and up to 8.6% from August 1, 2026 through July 31, 2027. Salinas is the only Monterey County city on the AG’s local ordinance chart. See our AB 1482 guide.

Just cause. The King City code index shows no rent stabilization or tenant protection chapter, so covered tenancies follow state just cause rules. See our just cause eviction guide.

King City rental property rules

Short-term rentals. Chapter 7.67, adopted by Ordinance 821 in 2023, requires a three-year administrative permit for stays under 30 days. It applies only to existing single-family homes in R-1, R-2, R-3, R-4, A and C-N, one per parcel, with a cap of ten guests. ADUs, guest houses and single rooms cannot be used.
New owners wait. Eligibility rests with the record owner when the ordinance took effect; after a sale, a new owner must wait two years before qualifying, and a permit is void if the property sells. Do not underwrite inherited short-stay income.
Lodging tax. Short stays owe the city’s 10% transient occupancy tax and need a TOT certificate and business license.
Property maintenance and nuisances. Chapter 17.09 sets property maintenance standards, and Chapter 7.51 includes an article on management of real property.
Seasonal employee housing. Chapter 17.79 regulates seasonal employee housing, relevant to farmworker rentals.

Older buildings, flood zones and transfer costs

Building age. Much of the R-2 through R-4 framework dates to 1973, so check the year built on every building. Pre-1980 wood-frame buildings deserve a seismic retrofit review, and buildings of three or more units with elevated balconies or walkways need SB 721 inspections.

Flood districts. King City maps primary and secondary flood plain districts. Get a flood determination and insurance quote before you commit.

Transfer tax. The city charges 27.5 cents per $500 under Chapter 3.08, separate from the county documentary transfer tax.

Underwriting a King City multifamily purchase

Confirm the district and check the unit count against the site-area-per-unit rule (2,500, 2,000 or 1,575 square feet).
Verify permits for every unit, and that each meets minimum floor area.
Read title for inclusionary or specific plan affordability covenants.
Classify units under AB 1482, model increases at or below 8.6% for covered units, and gather leases and estoppel certificates.
Exclude short-term rental income unless you will qualify for your own permit after the two-year wait.
Rebuild expenses with reassessed property tax, flood insurance and city transfer tax in our rental property analysis.
