SB 79 Allows 8-Story Buildings Near San Diego Trolley Stops

What SB 79 Actually Changes: The Specifics That Matter

Senate Bill 79, formally titled the "Abundant and Affordable Homes Near Transit Act," establishes state-mandated zoning standards that supersede local regulations in eight California counties, including San Diego County. According to the San Diego Union-Tribune, the law creates a tiered system based on transit service frequency and proximity.

Height Limits by Distance and Transit Type

For standard trolley stations (like most San Diego Trolley stops):

• Directly adjacent to station: Up to 8 stories (approximately 95 feet)
• Within 1/4 mile: Up to 6 stories
• Between 1/4 and 1/2 mile: Up to 5 stories

For high-frequency transit stops (72 or more stops per day):

• Directly at station: Up to 9 stories
• Within 1/4 mile: Up to 7 stories
• Between 1/4 and 1/2 mile: Up to 6 stories

This means every property within a half-mile walking distance of a trolley station now has significantly increased development rights—a change that typically takes years of community planning meetings and zoning battles to achieve.

Which San Diego Transit Lines Qualify

According to KPBS reporting, three transit systems in San Diego County qualify under SB 79:

• San Diego Trolley: All stations on the Blue, Orange, Green, and Copper Lines
• Sprinter rail line: All stations from Oceanside to Escondido
• MTS bus route 225: Only portions along Park Boulevard in San Diego

Notably, the Coaster commuter rail and Amtrak lines do not qualify because they lack sufficient service frequency. Most rapid bus lines also don't qualify unless they have dedicated lanes and 15-minute service intervals.

The San Diego Neighborhoods Most Affected by SB 79

While San Diego Mayor Todd Gloria stated that "about 85 to 90 percent of the new homes we've permitted are located near transit," suggesting the city is "already ahead of the game," the impact varies dramatically by neighborhood. Some areas already allow dense development, while others will see transformative change.

College Area and SDSU: Major Transformation Expected

The College Area near San Diego State University will see some of the most significant impacts. The San Diego City Council recently approved a new community plan for the College Area that allows 34,450 homes—more than double the previous plan's 16,700-home capacity, according to KPBS coverage.

Two trolley stations serve this area:

• SDSU Transit Center: The only underground trolley station in the entire San Diego network, located between College Avenue and Campanile Drive. This station serves as a major hub with multiple bus connections.
• 70th Street Station: Serves the eastern portion of the College Area along the Green Line.

Properties within a half-mile of these stations—particularly older single-family homes on larger lots along Montezuma Avenue, College Avenue, and El Cajon Boulevard—now have development potential that could be worth significantly more than their current assessed values reflect.

Mission Valley: Already Dense, But Room for More

Mission Valley already features substantial development near transit, with Fashion Valley Mall, Hazard Center, and numerous apartment complexes within walking distance of trolley stations. According to the San Diego Union-Tribune, neighborhoods like Mission Valley won't see as dramatic a change because local zoning already permits significant density.

However, underutilized sites—parking lots, aging strip malls, and low-rise commercial buildings—near the Mission Valley Center, Fenton Parkway, and Grantville stations could now be redeveloped into higher-density housing without requiring time-consuming rezoning processes.

Why SB 79 Creates Opportunities for Cash Buyers

Regulatory changes create a timing advantage: property values eventually adjust to reflect new development rights, but there's typically a lag between when laws change and when the market fully reprices properties.

Cash buyers can move quickly to acquire properties before three things happen:

1. Developers Identify Target Properties

Large-scale developers typically take 6-12 months to identify acquisition targets, conduct due diligence, and secure financing. During this window, individual property owners may not realize their land has increased in value due to the zoning change.

A single-family home on a 7,500-square-foot lot near the 70th Street Trolley Station that was worth $650,000 under previous zoning might now be worth $850,000 or more to a developer who can build a six-story, 45-unit apartment building on the site.

2. Real Estate Agents and Appraisers Catch Up

Most residential real estate agents focus on traditional sales comparables—what similar homes have sold for recently. It takes time for appraisers and agents to incorporate "highest and best use" analysis that accounts for development potential under new zoning.

Properties listed in early 2026, just after SB 79 takes effect, may be priced based on residential comparables rather than development potential. Cash buyers with knowledge of the new law can identify these undervalued opportunities.

3. The Market Fully Adjusts

According to RCLCO Real Estate Consulting, "transit-accessible lots just became a lot more valuable" under SB 79. The firm notes that properties near transit stations can now support projects that were previously economically infeasible under restrictive local zoning.

Research on transit-oriented development shows property values typically increase 15-20% within walking distance of new transit lines, according to Luxury SoCal Realty analysis. SB 79 creates a similar effect: it doesn't add new transit, but it dramatically increases what can be built near existing transit—functionally creating new development capacity.

The Development Economics: Why SB 79 Changes the Math

California's housing shortage is estimated at 3 million units statewide, according to CalMatters reporting. San Diego County faces an estimated shortfall of approximately 100,000 housing units.

SB 79 addresses this by making more projects financially feasible. According to Holland & Knight legal analysis, the law allows densities of up to 160 dwelling units per acre (or more with density bonuses) and floor area ratios of 4.5.

Streamlined Approvals Reduce Risk and Delay

One of SB 79's most significant provisions is ministerial approval for qualifying projects. This means projects that meet the law's criteria must be approved without discretionary hearings, environmental impact reports, or lengthy community input processes.

According to the National Law Review, streamlined approvals "reduce reliance on discretionary processes and streamline environmental review under the California Environmental Quality Act (CEQA)."

For developers, this dramatically reduces project risk. A typical discretionary development project in San Diego can take 18-36 months for approvals, with no guarantee of success. Ministerial approval under SB 79 can happen in 90-180 days with far greater certainty.

Specific Property Types With Increased Value Under SB 79

Not every property near a trolley station will see equal impact from SB 79. Certain characteristics make properties particularly attractive under the new law:

Larger Lots in Single-Family Neighborhoods

A single-family home on a 5,000-square-foot lot has limited development potential. But a property on a 10,000-15,000-square-foot lot (or an assemblage of adjacent properties) can support a substantial multi-family building.

In the College Area, look for properties along Montezuma Avenue, El Cajon Boulevard, and College Avenue with larger lot sizes. These corridors are within a half-mile of SDSU Transit Center and were previously zoned for lower-density development.

Aging Commercial Properties

Strip malls, car dealerships, and single-story commercial buildings on large parcels near trolley stations are prime candidates for redevelopment under SB 79. These properties often have:

• Existing commercial zoning that can be converted to mixed-use
• Large lot sizes suitable for substantial development
• Aging buildings with deferred maintenance, making redevelopment economically attractive
• Locations on major streets with good visibility and access

In Mission Valley, properties near the Fenton Parkway and Mission Valley Center stations fit this profile. In El Cajon, commercial properties along Main Street near the El Cajon Transit Center now have significantly increased development potential.

Corner Lots and Properties With Alley Access

Multi-family developments require parking, loading zones, and utilities access. Corner lots and properties with alley access make project design easier and more efficient, increasing their value to developers.

Properties Requiring Estate Resolution

Heirs who inherit properties near trolley stations may not be aware of the increased development potential under SB 79. These situations often create opportunities for cash buyers who can close quickly and help families resolve estates without the complexity of listing properties on the open market.

What Property Owners Should Do Now

If you own property within a half-mile of a San Diego Trolley station, SDSU Transit Center, or qualifying transit stop, SB 79 likely affects your property's value. Here's what to consider:

Understand Your Property's Development Potential

Not every property near transit will be attractive to developers, but it's worth understanding whether your property has characteristics that increase its development value:

• Lot size over 7,500 square feet
• Corner location or alley access
• Proximity to major streets and amenities
• Within a quarter-mile (closer is better) of a trolley station
• Current use that's lower than highest-and-best use under SB 79

Consider Timing for Maximum Value

There's a strategic timing question: sell now before the market fully adjusts, or wait for development interest to drive prices higher?

Cash buyers can offer speed and certainty. According to industry analysis, cash transactions can close in 7-14 days without financing contingencies, inspections, or appraisals that can derail traditional sales.

For property owners who need to sell quickly—due to financial pressure, estate settlement, or relocation—cash offers provide certainty while still capturing value from increased development potential.

Get Expert Valuation That Accounts for SB 79

Traditional residential appraisals focus on comparable sales of similar homes. But if your property has significant development potential under SB 79, you need valuation analysis that considers:

• Highest and best use under new zoning
• Development potential (how many units could be built)
• What developers are paying for similar sites
• Market absorption rates for new multifamily housing

Cash buyers who specialize in properties with development potential can provide this analysis and make offers that reflect the property's true value under SB 79.

The Long-Term Outlook: How SB 79 Reshapes San Diego

SB 79 becomes effective July 1, 2026, but its full impact will unfold over years. Expect to see:

First Projects Breaking Ground in 2027-2028

Even with streamlined approvals, projects need site acquisition, design, engineering, and construction planning. The first SB 79 projects will likely break ground in 2027, with completed buildings by 2028-2029.

Gradual Transformation of Transit Corridors

Neighborhoods won't change overnight. Redevelopment happens property by property as owners sell, developers acquire sites, and projects move forward. The College Area, Santee, and El Cajon will likely see more visible changes than already-dense areas like Mission Valley or Downtown.

Increased Competition for Transit-Proximate Sites

As developers recognize the opportunity, competition for properties near trolley stations will intensify, driving prices higher. This reinforces the advantage for cash buyers who can move quickly in 2026-2027 before competition peaks.

Ripple Effects Beyond the Half-Mile Radius

New housing supply near transit will affect broader market dynamics. If thousands of new apartments are built near trolley stations, it could moderate rent increases and home price growth across San Diego County by adding to overall supply.

Conclusion: Knowledge Creates Opportunity

SB 79 represents the most significant zoning change in San Diego in decades. By allowing six-to-eight-story buildings near every trolley station, the law transforms development potential for thousands of properties across the College Area, Mission Valley, Old Town, East County, and other neighborhoods.

Property owners who understand these changes can make informed decisions about timing, valuation, and whether to sell to cash buyers who recognize development potential. The window of opportunity—before the market fully adjusts to new zoning reality—is relatively short, likely 12-24 months after the law takes effect in July 2026.

For homeowners in transit corridors facing financial distress, inheritance situations, or simply wanting to sell quickly, cash buyers who specialize in properties with development potential offer speed, certainty, and fair pricing that reflects SB 79's impact on property values.

The next few years will reshape San Diego's landscape around transit corridors. Property owners positioned near trolley stations have an opportunity to benefit from regulatory change that typically takes decades to achieve—if they act with knowledge and strategic timing.
