San Diego Transit-Oriented Development: What SB 79 Allows in 2026
A parcel-first guide to housing near transit, with current City of San Diego requirements and a clear distinction between zoning capacity and homes actually built.
Key Takeaway
Start with the City’s SB 79 Eligible Sites (2026) layer, not a circle drawn around a station. Zoning capacity is neither a building permit nor a construction forecast.
SB 79 creates a transit-oriented housing development pathway in San Diego, but being near a trolley or bus stop is not enough to establish eligibility. The City says the law took effect July 1, 2026, with a phased local rollout: about 24% of the total areas took effect then. Its July 2026 development bulletin directs applicants to the SB 79 Eligible Sites (2026) layer in the City’s zoning portal. [1] [2]
Official sources checked October 8, 2026. This guide concerns the City of San Diego, not every city in San Diego County. Maps and implementation details may change. It is educational information, not a parcel-specific entitlement or legal opinion.
What makes this a different development model?
San Diego describes SB 79 as a way to allow qualifying multifamily housing around designated transit stops on residential, mixed-use, and commercial land. Its implementing bulletin permits residential-only projects as well as qualifying mixed-use projects; it does not require every proposal to include ground-floor shops. [1] [2]
For a developer, our suggested starting point is a housing and mobility brief: the intended household needs, the transit connection, the buildable site, and the approval pathway. That is a different feasibility exercise from assuming that any apartment building with retail underneath is automatically a transit-oriented opportunity.
Read the capacity numbers without turning them into a building forecast
The City’s planning page compares its initial 54 qualifying stops with the 74 stops identified by SANDAG on June 18, 2026. Using the updated set, the City reports approximately 1,047,000 homes of required planning capacity, versus 609,000 under current zoning, leaving 438,000 homes of additional capacity to plan for. These are the City’s planning estimates, not completed homes, issued permits, or a funded construction pipeline. [1: City planning figures]
Our interpretation: these figures explain the scale of the planning task, not the value of a particular lot. Do not multiply a citywide capacity headline by an assumed sale price and treat the result as evidence of demand or land appreciation.
Which sites are eligible now?
The City’s July 2026 Information Bulletin 479 says its SB 79 provisions apply only at locations identified on the SB 79 Eligible Sites (2026) layer in the Zoning and Permit Portal, or ZAPP. It also lists requirements involving zoning, certain rent-controlled housing and demolition histories, and mobile-home parks. A qualifying-stop map is therefore a starting point, not the whole eligibility test. [2: Site eligibility]
For a first review, follow this sequence:
- Locate the actual parcel in ZAPP and turn on the SB 79 Eligible Sites (2026) layer under Planning Areas.
- Check its underlying zoning and the applicable distance band.
- Have the project team investigate existing housing, occupancy and demolition history against the bulletin’s criteria.
- Ask Development Services to confirm the applicable pathway before relying on it in a purchase decision.
The planning page separately identifies areas that took effect in July, areas associated with the future Transit Village Plan, and low-resource areas shown for 2031. As of this review, the City says it aims to present the Transit Village Plan to the City Council in early 2027. That is a planning target, not an adopted outcome or guaranteed approval date.

What height and density does the City describe?
The City’s bulletin classifies San Diego’s eligible stops as Tier 2. Its published limits for eligible projects include the following distance bands; the complete bulletin contains additional standards and provisions that must also be checked. [2: Development standards]
- More than one-quarter mile and within one-half mile: the City’s planning summary lists 80 homes per acre, a 2.5 floor area ratio, and 55 feet of height. [1]
- Within one-quarter mile: the bulletin lists 100 homes per acre, a 3.0 floor area ratio, and 65 feet of height. [2]
- Within 200 feet: the bulletin lists 140 homes per acre, a 4.0 floor area ratio, and 85 feet of height. [2]
The bulletin also requires at least five dwelling units and a minimum density equal to the greater of 30 homes per acre or the base zone’s minimum. It notes that other local programs allowing equivalent or greater height, density, and floor area ratio remain available. [2]
Treat those figures as inputs for a qualified design and entitlement review, not a promise that every eligible parcel can physically accommodate the maximum. Ask for a concept plan and a written explanation of the applicable requirements before assigning a development premium to the land.
How to assess the real development opportunity
We recommend separating the feasibility work into four decisions instead of relying on a single “near transit” label.
- Eligibility: preserve the dated map result and obtain a written review of the parcel’s applicable rules.
- Design: commission a site-specific study covering unit layout, access, utilities, circulation, and the project’s applicable standards.
- Demand: gather current comparable rents or sales for the proposed unit types; test the actual walk to transit rather than relying only on a straight-line radius.
- Economics: obtain current construction and financing proposals, identify required affordability and other obligations with the project team, and model a slower or more expensive delivery scenario.
For an existing property owner, the practical question is what a professional feasibility study could establish, not whether a new law automatically raises the value of the property. For a buyer, request the evidence behind an advertised development opportunity and distinguish an adopted rule from a proposed plan.
Common SB 79 questions
Is every property within half a mile of a station eligible?
No. San Diego has phased implementation, and Bulletin 479 directs applicants to the eligible-sites layer and additional site criteria. Use the City’s current parcel information rather than assuming proximity alone establishes eligibility. [2]
Does the 438,000 figure mean that many homes will be built?
No. The City labels it additional capacity it needs to plan for above current zoning. The figure does not represent construction commitments or a delivery schedule. [1]
Must a transit-oriented project include retail?
No. The bulletin expressly lists residential-only projects among the allowed uses, alongside mixed-use alternatives with specific requirements. Review the complete use standards for the actual proposal. [2]
The bottom line
Transit-oriented housing is worth studying as its own development strategy, with eligibility and design examined before acquisition pricing. The most useful next step is a documented parcel review, not a promise about future density or appreciation. Compare this approach with our Inland Empire industrial development analysis to see how different development types demand different evidence.
