These are the primary sources for accessory dwelling unit regulations in Ocean City: the city's own zoning code, planning department pages, and permit guides. Start here before talking to anyone: the rules below are what your permit reviewer will apply.

Rules at a glance

Detached (backyard) ADU
Conditional

The program covers voluntary conversion of existing single family or two family dwellings or accessory buildings, and eligibility extends to owners who occupy the principal structure on a lot on which an accessory unit will be located, so a unit in a detached accessory building is possible. It is allowed only through the deed-restricted affordable accessory apartment program, only in the R-2 and RMF zone districts excluding bayfront and oceanfront lots, and only on fully conforming lots.

§ 25-211.1, § 25-211.2, § 25-211.3, § 25-211.7
Attached or internal ADU
Conditional

Conversion of an existing single family or two family dwelling to accommodate an accessory apartment is the core of the program, but only for owner-occupants who rent the unit to low- or moderate-income households, and only in the R-2 and RMF zones off the bayfront and oceanfront. The accessory apartment and any existing unit must each have a separate door with direct outside access, and the project may not add a door to the front facade of the principal structure.

§ 25-211.1, § 25-211.2, § 25-211.3, § 25-211.4
Maximum size
950 square feet gross floor area maximum, 450 square feet minimum. The unit must contain one kitchen with sink, refrigerator, and cooking facilities and one full bathroom with sink, toilet, and tub or shower.

Section 25-211.4 sets the gross floor area at no less than 450 and no more than 950 square feet and specifies the required kitchen, bathroom, and separate exterior door.

§ 25-211.4
Owner occupancy
Required

Only owners who occupy the single family detached or two family dwelling as their primary residence, or who occupy the principal structure on the lot where the accessory unit will be located, are eligible to participate in the accessory apartment program.

§ 25-211.2
Extra parking
Yes. Accessory apartments created by new construction must conform to the parking requirements of the zone district (R-2 or RMF); accessory apartments created through renovation or rehabilitation of existing structures must add one additional off-street parking space. All spaces must comply with the ordinance parking standards.

Section 25-211.5 splits the requirement by whether the unit is new construction or a conversion of an existing structure.

§ 25-211.5
Approval process
Permitted use

Accessory apartments are permitted (not a conditional use) but only in the R-2 and RMF zone districts. Applications are filed with a city-appointed program administrator and must include floor plans, sketch elevations with photographs, and a site development plan prepared by a licensed engineer or land surveyor; the unit must also comply with New Jersey building codes as enforced by the city Construction Code Official. No planning board or conditional use hearing is described in the section.

§ 25-211.3, § 25-211.6, § 25-211.11
Rental restrictions
The unit may be rented only to low- or moderate-income households, with tenant income qualification proof required by the city, which administers the program. A deed restriction to that effect must be recorded in the Cape May County Clerk's Office and remains in place for 10 years from initial occupancy. Owners who fail to comply must pay the city a penalty of 125 percent of any grant or loan money received. The stated purpose is year-round occupancy. A code search found no short-term rental rule that specifically references accessory apartments.

Sections 25-211.2 and 25-211.9 impose the low/moderate income limitation and the 10-year recorded deed restriction with the 125 percent repayment penalty; 25-211.1 frames the program as creating units for year-round occupancy; 25-211.10 pairs the restriction with a grant of at least 10,000 dollars per unit funded by a development fee ordinance.

§ 25-211.1, § 25-211.2, § 25-211.9, § 25-211.10
The fine print: 7 caveats that can change the picture
  • This is a deed-restricted affordable housing program, not a general ADU allowance: accessory apartments exist to meet Ocean City's Fair Share Housing Obligation, may be rented only to low- or moderate-income households under a recorded 10-year deed restriction, and come with a city grant of at least 10,000 dollars per unit (§ 25-211.1, § 25-211.9, § 25-211.10).
  • Allowed only in the R-2 and RMF zone districts, and never on bayfront or oceanfront lots (§ 25-211.3).
  • Only lots and structures that conform in all respects to zoning standards (use, height, habitable stories, lot area and width, all yards, building and impervious coverage, parking, landscaping, and design standards) qualify (§ 25-211.7).
  • No more than one accessory apartment per lot, and the citywide total is capped at the number Ocean City may credit toward its Council on Affordable Housing Fair Share obligation (§ 25-211.8).
  • The owner must occupy the dwelling, or the principal structure on the lot, as a primary residence to participate (§ 25-211.2).
  • The program targets year-round occupancy; these units are not a path to seasonal or short-term rentals (§ 25-211.1).
  • Noncompliance with the deed restriction triggers repayment of 125 percent of any city grant or loan received (§ 25-211.9).

Summarized from Ocean City's ordinance text, read July 2026; every row links the code section it came from. Rules often vary by zone and lot, so treat this as orientation, not a permit determination, and confirm with the planning department before you commit to a design.
