Dana Point ADU rules in plain English

What you can build in the City of Dana Point.

These rules apply outside the Coastal Zone. Inside the Coastal Zone, the City's Local Coastal Program rules still apply until the Coastal Commission acts, and we confirm which rules apply to your lot. The basics below are for a single-family lot, under the ADU rules the City adopted in September 2026.

How many

An ADU, a junior ADU and a detached ADU

On a single-family lot, an ADU and a junior ADU inside the house, or the ADU in an existing accessory building, can be combined with one new detached ADU of up to 800 sq ft with 4 ft side and rear setbacks. Larger ADUs follow the City's own standards, and we confirm how many fit your lot.

DPZC 9.07.212.E
Size

850 or 1,000 sq ft

Outside the state-law path, an ADU can have up to 850 sq ft of living space with one bedroom or less, or 1,000 sq ft with more. An attached ADU added to an existing house can be up to half the house's living area, and never has to be smaller than 800 sq ft. A conversion has no size cap, and an ADU can be as small as 150 sq ft.

DPZC 9.07.212.F.6
Height

16 ft detached, 25 ft attached

A detached ADU can be 16 ft tall, or 18 ft within a half-mile walk of a major transit stop, where 2 more feet may be allowed to match the house's roof pitch. An attached ADU can be 25 ft or the zone's limit, whichever is lower, and two stories.

DPZC 9.07.212.F.5
Setbacks

4 ft from the side and rear

Nothing, including HVAC equipment, stairs or patio covers, can project into a setback. The front follows the zone's setback unless that would rule out an 800 sq ft ADU, and a conversion or a same-size rebuild needs no setback.

DPZC 9.07.212.F.4
Parking

One space, with exceptions

Outside the state-law path, an ADU needs one off-street parking space, unless it's an efficiency unit, within a half-mile walk of public transit including bus stops, part of the house or an existing accessory building, or another exception applies. A junior ADU adds no parking.

DPZC 9.07.212.F.8; 9.07.215
Renting and selling

Rent for 30 days or more

An ADU can't be rented for less than 30 days, and it can't be sold separately from the house unless the sale complies with state law and the Subdivision Map Act.

DPZC 9.07.212.F.2
Public Safety Areas

In six areas, an ADU or junior ADU outside the state-law path, on a lot whose existing building doesn't meet current parking or driveway-length standards, needs a discretionary Site Development Permit: Lantern Village (RMF14 and RSF22), Nottingham Way and Cheltam Way (RMF14), Doheny Village (C/R), and Capistrano Beach (RD-14 and RSF7/RSF12).

We check whether your lot is in one, and whether that area is inside the Coastal Zone.

Worth knowing in Dana Point

An ADU that misses these standards can still seek a discretionary Site Development Permit from the Planning Commission, but never with side or rear setbacks under 4 ft (other than a conversion or a same-size rebuild), above the zone's height limit except as state law allows, or with more than 1,200 sq ft of living space, except for certain units allowed under state law.

We confirm with the City when the new rules take effect outside the Coastal Zone, whether the state housing department has reviewed them, and how many ADUs your lot can have alongside a junior ADU.

Changing on January 1, 2027

SB 1117 limits the impact fee on an ADU over 750 sq ft to the area above 750 sq ft, in proportion to the main house, for up to two ADUs on a lot. ADUs of 750 sq ft or less still pay no impact fee.

AB 956 lets you build two new detached ADUs on a single-family lot through the state's approval path. On that path a city can cap each one at 800 sq ft.

What changes for ADUs on January 1, 2027

How it works

From your lot to move-in.

Step 1

Pick a model

Choose a model and finishes online, or book a free consultation to talk it through.

Step 2

Site assessment

We visit your lot, check utilities, access and the City's rules, and give you one all-in price before you sign.

Step 3

Design and permits

We finish the plans and run the permit with the City of Dana Point from submittal to approval.

Step 4

Build and move in

We build on site and manage the job through final inspection and your certificate of occupancy.

Typical timeline: 8 to 12 months from start to finish. About 1 month of design, 2 to 4 months of permits and 3 to 5 months of construction. Your lot and the City's review times can move it.
