You’re planning an addition, considering a subdivision, or checking a San Diego property before buying or selling. The city’s 2026 Land Development Code update changes rules relevant to those plans, including remodel parking, subdivision conditions and enforcement penalties. Start with the lot’s location, then check the conditions attached to the change you want to use.
The update took effect July 15, 2026 outside the Coastal Overlay Zone, with one stated airport-area exception. Approval inside the overlay is anticipated in 2028.
This is general information, not legal or tax advice. The City of San Diego’s adopted updates page gives the adoption status and timing; the city’s item list describes the individual changes below.
What took effect outside the Coastal Overlay Zone?
The 2026 Land Development Code update took effect July 15, 2026 outside the Coastal Overlay Zone, except for one item within the Transition Zone of the MCAS Miramar Airport Influence Area.
The San Diego City Council held its first reading May 11, 2026, under Agenda Item 204, and its second reading June 8, 2026, under Agenda Item 613. The city’s page labels the update adopted June 15, 2026 and identifies O-22109 as the 2026 Land Development Code Ordinance. That page also lists a contact for development code questions.
For your property, the effective date answers when the update took effect in the applicable area. The conditions of each item answer a separate question: whether the change fits your planned work.
The airport-area exception deserves its own check. A location outside the Coastal Overlay Zone alone doesn’t settle the timing for the excepted item within that Transition Zone.
Why is the Coastal Overlay Zone on a different track?
The update requires California Coastal Commission certification inside the Coastal Overlay Zone, and the city is working to obtain it.
As of 30 October 2026, the update is not yet approved there; approval inside the overlay is anticipated in 2028. That is anticipated timing, not an approval already in place.
If the lot is in the Coastal Overlay Zone, ask which version of the code applies before relying on the parking or subdivision changes. The effective date outside the overlay answers the timing question for that area.
You can read about how coastal permits work in another city for context. That guide concerns Carlsbad. For a San Diego lot, keep your question tied to San Diego’s code and the certification status of this update.
What does the update say about enforcement penalties?
The city’s item list describes civil penalties associated with Municipal Code or State Building Code violations increasing to up to $10,000.
Item 1 in the 2026 Land Development Code Update, Citywide List describes the previous structure as ranging from $100 to $1,000 per day, depending on the violation’s severity and duration. The list says that structure had not been updated since 2007.
Whether Item 1 survived unchanged in O-22109 remains unverified because the adopted ordinance PDF could not be text-read; the penalty description here comes from the city’s item list.
The $10,000 figure is an upper limit in that list, not a fine that has been levied.
If you’re selling, keep the enforcement description separate from the questions covered in the California seller disclosure guide. A penalty amount doesn’t answer what you need to disclose about a property. Use the item number when asking about the enforcement change so the question stays tied to the specific provision.
When does the remodel parking change apply?
The city’s item list describes removing the additional parking requirement outside a Transit Priority Area for qualifying remodels or additions to existing single dwelling units.
Item 47 implements state AB 1308. The list describes the city’s additional parking requirements as arising when bedrooms are added in the campus impact area of the parking overlay zone and when previously conforming homes are expanded.
The development cannot exceed the base zone’s maximum size limits, including height, lot coverage and floor area ratio. Planning Commission staff report PC-26-005 also says the change applies only if there is one dwelling unit on the lot. The fact that your project is a remodel or addition doesn’t, by itself, answer whether it fits those conditions.
What does the small lot subdivision item allow?
The city’s item list describes ministerial subdivision of up to 10 dwelling units on lots of 1.5 acres or less in single-dwelling unit zones, outside a Very High Fire Hazard Severity Zone.
Item 41 addresses SB 684, SB 1123 and AB 130. It allows remainder parcels and sets a condition on selling the resulting lots: lots must be sold with a dwelling unit unless reserved for open space, common area or a remainder parcel.
That sale condition belongs in your review of a subdivision plan from the start. A plan to divide land and sell the resulting lots needs to account for the dwelling-unit requirement and its stated exceptions.
Item 40 concerns lots zoned for multiple dwellings of 5 acres or less. Keep those descriptions separate. For a single-dwelling unit lot, Item 41 provides the relevant acreage description; Item 40’s larger acreage limit concerns different zoning.
What else is in the adopted package?
The city’s adopted lists total 134 items (103 citywide, 31 downtown), including changes concerning development impact fees and ADU terminology.
Item 7 removes the Complete Communities Housing Solutions development impact fee waiver for homes under 500 square feet because development impact fees are now scaled by home size.
Item 12 clarifies that, for ADU regulations, multiple single dwelling units on one lot are each single dwelling units, and an ADU on a lot with a single dwelling unit does not make the lot a multiple dwelling unit.
The city separately identifies O-22110 as the 2026 Centre City Planned District and Gaslamp Quarter Planned District Ordinance. The downtown items are included in the adopted-list total.
The staff report counts 139 proposed amendments at the Planning Commission stage. That earlier proposal count describes a different stage of the process. Use the adopted total when referring to the package on the city’s adopted updates page.
What should you check before relying on a change?
Check the applicable code version and the specific item’s conditions before relying on a change for your property plans.
For remodel parking, identify whether the property is outside a Transit Priority Area. Check the dwelling-unit count against the staff report’s condition, then compare the proposed work with the base-zone size limits. These are separate parts of the parking description.
For Item 41, match the lot’s zoning, acreage and fire-hazard designation to the city’s list. Review the sale conditions alongside the subdivision description, including the exceptions for open space, common area and remainder parcels.
Name the item when asking about your property. Asking whether Item 47 applies to an addition gives the question a clearer focus than asking whether the entire update applies. Include the code-version question if the lot is in the Coastal Overlay Zone.
I worked with a San Diego homeowner who had already begun sketching an addition when the 2026 Land Development Code update came up. He wanted a simple list of everything that had changed, but the provision affecting his property had to be traced through the ordinance and existing code. We focused on the section relevant to his project instead of assuming the entire update applied to him.
The short version
San Diego’s update changes parking, subdivision and enforcement rules, with the relevant conditions depending on the item and the property’s location.
Outside the Coastal Overlay Zone, the update took effect July 15, 2026, with the stated airport-area exception. Approval inside the overlay is anticipated in 2028.
For your plans, connect the specific change to the lot: dwelling-unit count and base-zone limits for remodel parking, or zoning, acreage, fire-hazard designation and sale conditions for Item 41.
