"The second unit may be occupied by an individual adult or two senior adults, and may be attached to or detached from the primary single family unit, but may not be sold as a separate dwelling unit."
That sentence comes from Dana Point's zoning code as it reads this fall. It was first adopted in 1994 and amended in 1996. On September 15, 2026, the City Council voted 3–0, with two members absent, to put it back into the code text. The vote came under Ordinance 26-08. For any property inside the city's Coastal Zone, it governs what most buyers would call an ADU.
This matters most at the offer stage. A listing that mentions "ADU potential" means one thing on an inland lot and something much narrower inside the Coastal Zone. Buyers often look at those two kinds of lots in the same afternoon.
Where the line falls, and why your map app won't show it
Dana Point's adopted Housing Element puts the city at 4,134 acres, and 1,993 of them sit in the Coastal Zone. That is "Approximately 48%." The other half of the city is governed by a separate ADU ordinance written to follow state law.
No published list sorts Dana Point neighborhoods by which side of the line they fall on. The city's own Coastal Zone and appeal boundaries map is labeled as not an official map and warns that it may leave out land where the Coastal Commission keeps direct jurisdiction. You can't tell from a neighborhood name, a street, or a guess about distance from the water. City Planning staff confirm it parcel by parcel.
What the coastal rule actually asks for
The reinstated Section 9.07.210 lets an owner apply for a second unit only where a single-family home already exists. The owner applies for a Conditional Use Permit, and the Planning Commission must find that every standard below has been met.
| Standard under Ordinance 26-08 | Why a buyer would care |
|---|---|
| Conditional Use Permit, decided by the Planning Commission | Approval is discretionary and goes through a hearing |
| Occupancy by "an individual adult or two senior adults" | Limits who can live in the unit |
| Cannot be sold separately | The unit stays tied to the main house |
| Attached: 30% of the primary home's living area. Detached: 1,200 sq ft maximum | On a smaller house, an attached unit is capped at a small footprint |
| No encroachment into setbacks required for the main house | Side and rear yards that look usable may not be |
| One additional parking stall | Tight lots may not fit one |
| Affordable to low- and moderate-income households "for the life of the project" | Limits the rent the unit can earn |
| CUP and all conditions recorded with the County Recorder | The permit and its conditions are part of the public record |
The affordability standard has the biggest effect on value. The ordinance defines "the life of the project" as the length of time the second unit is occupied. A plan built around market-rate rent from a coastal-zone unit runs into a standard that ties the unit to low- and moderate-income affordability. The recording requirement matters for existing homes too, because the ordinance requires a second unit's CUP and conditions to be recorded with the County Recorder.
Why a 1994 rule is still the operative one
The rule stayed legally operative even while it was missing from the printed code. According to the city's September 15 staff report, the council adopted Ordinance 21-06 in August 2021 to put state ADU law into effect, and that ordinance was never meant to apply in the Coastal Zone without a Coastal Commission-approved amendment to the city's Local Coastal Program. In the process, the coastal second-unit language was "inadvertently removed" from the code text.
No LCP amendment was ever approved, so the old provisions stayed legally binding in the Coastal Zone. Staff kept applying them, and the report says the Coastal Commission still treats that language as the operative rule. Ordinance 26-08 restored the wording to the printed code so the code matches what was already in force.
That explains how a buyer could miss it. As recently as this fall, the city's ADU permit page still sent applicants to Ordinance 25-04, with a warning that it does not apply in the Coastal Zone. According to the Dana Point Times, the coastal item passed its September 1 first reading without council discussion.
The state housing agency agrees with the city on this point. In its August 13, 2025 notice to Dana Point, the California Department of Housing and Community Development wrote that "within the coastal zone, provisions of a fully certified Local Coastal Program (LCP) that conflict with State ADU law supersede the relevant provisions in State ADU Law." The same letter encourages the city to update its LCP and to label any coastal-only provisions clearly.
Meanwhile, the inland half has moved the other way
Inland, the rules moved in the opposite direction. HCD issued a notice of violation to the city on December 10, 2024. In August 2025 it found the replacement ordinance, 25-04, still noncompliant, with eight of the original 12 findings unresolved. Voice of OC reported that a February 2025 council vote had required a special permit for ADUs in six areas staff identified over parking and safety concerns.
The city adopted HCD's redlined edits through Urgency Ordinance 25-11 on September 18, 2025. Its response letter said it did so rather than risk losing Housing Element certification. HCD followed with a technical-assistance letter on June 8, 2026. After that, the permanent ordinance, ZTA26-0002, dropped Public Safety Area review for ADUs the city must approve by law and kept it only for the others. The city's report states plainly that these provisions do not govern coastal projects until an LCP amendment is approved by the Coastal Commission and adopted locally.
So over the past two years, the state has pushed Dana Point's inland ADU rules toward state standards, while the coastal rule has stayed where it was in 1996. The gap between two lots a short drive apart is wider today than it was in 2024.
What could change, and on what timeline
Three developments affect how long this split might last.
- SB 1077 guidance. On July 1, 2026, the Coastal Commission published guidance on LCP amendments for coastal ADUs. It urges cities to bring their ADU policies in line with state law while keeping Coastal Act protections, and it describes minor, de minimis, and major amendment tracks.
- Dana Point's stated intent. City staff say they will review that guidance and consider a future LCP amendment to reconcile the second-unit rule with ADU law. None has been adopted, and it would need Coastal Commission approval before taking effect.
- AB 462. Under AB 462, which took effect when it was signed in October 2025, a complete coastal ADU permit application must be decided within 60 days, and the Coastal Commission can no longer hear appeals of a local ADU decision under Coastal Act section 30603. Those changes speed up the process. They do not change the substantive standards a project in Dana Point's Coastal Zone must meet.
Until an amendment is certified and adopted, the 1994 rule is the one in force for coastal-zone lots.
The same line governs remodels
Many buyers who look at a lot for an ADU also plan a larger remodel, and the Coastal Zone line affects that work too. The city code generally requires a coastal development permit for work in the Coastal Overlay District unless the project is exempt. In nearshore, 300-foot beach, or scenic-resource settings, a CDP can be triggered by any of these:
- an interior floor-area increase of 10% or more
- an added story or loft
- a height increase of more than 10% of the structure's existing height
- a new detached structure
- demolition of more than half the exterior walls
The city's CDP application checklist lists residential fees of $4,628 for minor work with no bluff or habitat issues, and $7,172 for major or bluff-top work. Both add a $50 environmental assessment fee, plus deposits and fees for any related permits. The city's Planning FAQ still shows an older $1,633 figure, so confirm the current fee with Planning before you budget. The FAQ also says the city reviews an application for completeness within 30 days.
Questions to bring to City Planning before the offer
- Is the parcel in the Coastal Zone, an appeal area, or Coastal Commission retained jurisdiction? The city's map is unofficial, so this answer comes from staff.
- If it is coastal, which standards in Section 9.07.210 would apply to this lot? The 30% attached cap, setbacks, and the extra parking stall all depend on the specific house and lot.
- If a second unit already exists, is there a CUP on record? The ordinance requires the permit and its conditions to be recorded with the County Recorder.
- Would the planned remodel reach any of the CDP triggers above? The answer decides whether a coastal development permit enters the timeline.
How those answers affect value or rent is a question for your attorney, appraiser, and tax advisor.
A few direct questions
Does California's ADU law apply in Dana Point's Coastal Zone? State law still applies, but HCD's 2025 letter says provisions of a fully certified LCP that conflict with it take precedence inside the coastal zone. Dana Point's certified LCP includes the second-unit rule.
Did Ordinance 26-08 create new restrictions? According to the city, it restored text that had stayed legally binding through its certified LCP since the 1990s. Staff had kept applying it after the 2021 code edit dropped it from the printed code.
Is a change coming? The city says it will consider an LCP amendment in light of the Coastal Commission's July 2026 guidance. Until one is certified and adopted, the rule above governs coastal parcels.
