Multifamily and Duplex Properties for Sale in Carmel-by-the-Sea: Zoning and Rent Rules

What multifamily in Carmel-by-the-Sea looks like

Income property in Carmel is scarce and small. Most of it is in three forms: apartments above shops in the village core, small courtyard apartment and condominium buildings on the R-4 and RC blocks around the commercial district, and cottages with a guesthouse or accessory unit on the residential streets. Large complexes are effectively ruled out by the code, which caps site size and building size. A typical purchase is two to eight units, often in an older building with a long permit history. For loans, see financing 2-4 unit properties and apartment building loans.

Where the zoning allows it

Carmel-by-the-Sea is an incorporated city in the coastal zone, so its Title 17 code governs, and new units need coastal development review under the Local Coastal Program certified in 2004, according to the City’s LCP page.

Counting units. In R-4, the density count includes apartments, houses, guesthouses, condominiums, accessory units and commercial shop spaces. On R-4 sites over 4,000 square feet, at least half the units must be rental apartments, and in the commercial districts condominiums are limited to small sites or projects with at least as many rental units.

Unit mix. Chapter 17.14 sets a 400-square-foot minimum unit size. Projects of three or more units must include a mix, with at least a quarter between 400 and 650 square feet.

Rebuilding. Lawful R-4 buildings that exceeded density before March 7, 1990 may be rebuilt at the same unit count if the new design meets current standards. Residential units in the commercial districts cannot be demolished or converted without replacement housing.

ADUs and SB 9. Accessory units count toward R-4 density. State ADU law and SB 9 apply to qualifying R-1 lots, but properties on a historic register are excluded from SB 9, and coastal review and water still apply. Confirm the City’s current ADU standards. See our ADU investment guide.

Rent rules: state law only

Rent caps. The Attorney General’s rent cap page, updated July 16, 2026, puts Monterey County in the All Other Counties region: 7.7% for increases from August 1, 2025 and 8.6% for increases from August 1, 2026 through July 31, 2027. Its chart of local ordinances lists only Salinas in Monterey County, so Carmel units follow state law. See our AB 1482 guide.

Just cause. We found no Carmel tenant protection chapter, so covered tenancies fall under the state’s just cause rules. See our just cause eviction guide.

Carmel-by-the-Sea rental property rules

• No new short-term rentals. The City’s short-term rental page says rentals under 30 consecutive days are prohibited in R-1 and in CC, SC and RC except lawful hotels, motels and permitted rentals. Units permitted before Ordinance 2019-03 are legal nonconforming and transfer with the property but cannot move.
• Housing incentive transient units. In CC, SC, RC and R-4, a use permit can allow one transient unit for every three new rental units, one low-income and one moderate-income, with two of the three at least 650 square feet. Each transient unit needs an off-street space.
• Business license tax. Chapter 5.04 taxes gross receipts at $1.00 per $1,000, but its definition of gross sales excludes rental income from two or fewer residential units when that is the owner’s only rental income. Owners of three or more units should confirm licensing with the City.
• Parking. R-4 dwelling parking must be on site, and in-lieu fees are not available, so a building without garage spaces may be legal nonconforming.

Water, coastal review and older buildings

Water decides what can be added. The Monterey Peninsula Water Management District must issue a water permit before a building permit can set a meter, add one or intensify use on an existing connection, so adding an ADU or splitting a large unit can turn on water credits rather than zoning. Because the city is wholly in the coastal zone, new units also need coastal development review.

On Block 37, Section 17.12.050 protects a coastal view by capping structures and trees at the 350-foot contour, so check viewshed limits before planning an addition there. Much of Carmel’s apartment stock is older wood-frame construction, so a seismic retrofit review makes sense, and buildings of three or more units with elevated balconies need SB 721 inspections.

Underwriting a Carmel-by-the-Sea multifamily purchase

1. Confirm the district and density. Count every unit, including guesthouses and shop spaces in R-4, against the 33-unit-per-acre base.
2. Verify the permit history of each unit and whether any rebuild right from before March 1990 applies.
3. Check for legacy transient rental permits and price them separately from long-term units.
4. Pull MPWMD records for the meters and any water credits before planning added units.
5. Classify each unit under AB 1482, model increases at or below 8.6%, and collect leases and estoppel certificates.
6. Rebuild expenses with reassessed taxes, insurance and deck inspections in our rental property analysis.
