San Diego rent control 2026 No local RSO. Measure E (2020 rent control ballot initiative) failed 58% No. AB 1482 cap ≈ 8.2% (5% + ~3.2% San Diego-Chula Vista-Carlsbad MSA CPI) for pre-2011 covered units. Post-2011 buildings: 15-year exempt. Large military housing market. Downtown condo HHBO-notice requirements.

San Diego’s 2026 cap: AB 1482 formula and the SD-Carlsbad MSA CPI

Under California Civil Code §1947.12(a)(1), the maximum annual rent increase for a covered San Diego residential rental unit is the lesser of:

1. 5.0% plus the percentage change in the CPI-U for the San Diego–Chula Vista–Carlsbad Metropolitan Statistical Area (sometimes shortened to the “San Diego-Carlsbad MSA” in BLS publications), All Items, for the 12-month period ending on April 1 of the year prior to the increase (or the most recently published 12-month period ending before the effective date of the increase); OR
2. 10.0% absolute ceiling.

For 2026, the San Diego-Chula Vista-Carlsbad MSA CPI-U (April 2024–April 2025) is approximately 3.2%. Calculation: 5% + 3.2% = 8.2%, below the 10% ceiling. San Diego’s 2026 AB 1482 cap for covered units is approximately 8.2%.

The San Diego MSA is a separate BLS measurement area from the Los Angeles-Long Beach-Anaheim MSA, the San Francisco-Oakland-Hayward MSA, and the Riverside-San Bernardino-Ontario MSA. Properties in San Diego County use the San Diego-Chula Vista-Carlsbad CPI figure regardless of proximity to Los Angeles or the Mexican border. Properties in Chula Vista, National City, El Cajon, Escondido, Oceanside, and all other San Diego County cities use the same San Diego MSA CPI and arrive at the same ~8.2% AB 1482 cap for 2026 — assuming they are covered units (pre-2011 first CoC) and have not been exempted by another provision.

Why is San Diego’s cap slightly higher than LA? The SD-Carlsbad MSA CPI running ~3.2% versus the LA-Long Beach-Anaheim MSA at ~3.0% reflects differences in local inflation dynamics — housing construction costs, service-sector labor markets, and the outsized military and defense-economy influence on San Diego consumer prices. The 0.2 percentage point difference is modest in practical terms (a $2,000/month unit: SD cap allows $2,164; LA cap allows $2,160 — a $4/month difference) but is the legally controlling figure.

Why San Diego has no local rent control ordinance

San Diego has a long history of rejecting local rent regulation. The city enacted a brief rent-control ordinance in the 1970s during the initial wave of California rent control activism, but it was short-lived. Unlike Los Angeles (which enacted its RSO in 1978), San Francisco (1979), Oakland (1982), Berkeley (1982), or Santa Monica (1979), San Diego allowed its local rent regulation framework to lapse and did not maintain a permanent RSO.

Several structural factors explain San Diego’s persistent resistance to local rent control:

• Military homeownership culture: A large share of San Diego’s population is connected to the military, either active-duty, veterans, or defense-industry workers. Military culture tends to favor property rights and market-based housing frameworks.
• Development-friendly political history: San Diego’s City Council and mayor’s office have historically been aligned with development interests, particularly in downtown revitalization efforts (Gaslamp Quarter, East Village, Little Italy). Rent control was perceived as threatening to development momentum.
• Costa-Hawkins constraint: After February 1, 1995, any new local RSO in California can only cover buildings that received their first certificate of occupancy before that date. San Diego’s pre-1995 rental stock is concentrated in older urban neighborhoods — a narrower coverage universe than a ballot measure’s proponents might promise.
• Statewide AB 1482 framing: When AB 1482 took effect on January 1, 2020, it provided a statewide floor for covered buildings without requiring a local ordinance. This reduced the urgency for local action among moderate voters.

San Diego Measure E (2020): the city’s only modern rent control vote

Measure E was the defining moment in San Diego’s modern rent control history. Placed on the November 2020 general election ballot through a citizen-initiated petition process, Measure E would have:

• Established a local rent stabilization ordinance for the City of San Diego (not all of San Diego County)
• Capped annual rent increases for covered units at the lesser of 5% or the rate of inflation (CPI)
• Limited coverage to buildings with a first CoC before February 1, 1995 (Costa-Hawkins compliance)
• Created a San Diego Rent Board to administer petitions, banked increases, and hardship claims
• Added just-cause eviction protections beyond AB 1482’s §1946.2 framework

The measure failed with approximately 58% voting No and 42% voting Yes. The No campaign was funded primarily by real estate industry groups and apartment associations, who emphasized concerns about housing supply restriction and landlord disinvestment. The Yes campaign was backed by tenant advocacy groups, UNITE HERE Local 30, and progressive city council members.

The outcome was particularly notable because Measure E was on the same ballot as Proposition 21 (the statewide Costa-Hawkins repeal initiative), which also failed statewide by approximately 60% No. San Diego’s result was consistent with the broader California trend: voters in 2020 were unwilling to expand rent control significantly even in a year of unprecedented housing affordability pressure. No successor to Measure E has been placed on the San Diego City Council agenda or ballot as of 2026.

Costa-Hawkins and the permanent constraint on any future San Diego RSO

The Costa-Hawkins Rental Housing Act (Cal. Civ. Code §§1954.50–1954.535) fundamentally constrains what any future San Diego local RSO could accomplish. Under Costa-Hawkins:

• Any new local rent control ordinance enacted after February 1, 1995 may only cover buildings that received their first CoC before February 1, 1995 (§1954.52(a)(1)). Buildings constructed after that date are permanently exempt from any local RSO, no matter when the ordinance is enacted.
• Single-family homes and condominiums are categorically exempt from any local RSO (§1954.52(a)(2)–(3)) when the owner provides the written exemption notice at lease commencement — a constraint that applies regardless of building age.
• Vacancy decontrol (rent reset to market on tenancy turnover) is required under any Costa-Hawkins-compliant local RSO (§1954.53) — limiting the long-term coverage of even pre-1995 buildings to continuous-tenancy situations.

California voters rejected statewide Costa-Hawkins repeal in Proposition 10 (November 2018, ~61% No) and Proposition 21 (November 2020, ~60% No). Both failed statewide and both failed in San Diego County by similar margins. Costa-Hawkins remains in effect as of 2026. Any San Diego local RSO enacted today could only cover pre-February 1995 buildings in multi-unit structures — a smaller and older share of San Diego’s rental stock than a post-Measure E observer might expect.

AB 1482 coverage analysis: which San Diego rentals are covered in 2026

Because San Diego has no local RSO, the AB 1482 15-year rolling new-construction exemption (§1947.12(d)(4)(A)) is the primary coverage threshold for San Diego landlords and tenants. The analysis is simple for most San Diego units:

1. First certificate of occupancy (CoC) date: If the building received its first CoC before approximately 2011 (2026 minus 15 years), the unit is within the AB 1482 coverage window — assuming no other exemption applies. If the building received its first CoC in 2011 or later, the unit is exempt from AB 1482 under the 15-year rolling exemption.
2. Unit type: SFRs and condominiums in covered buildings are only exempt if the owner provided the written HHBO notice at commencement of tenancy (§1947.12(d)(5)(B)). Without that notice, an SFR or condo in a pre-2011 building is AB 1482-covered.
3. Just-cause threshold: Even covered units are only subject to AB 1482’s just-cause eviction protections (§1946.2) after the tenant has continuously occupied the unit for 12 months (or any household member has been there for 12+ months). Rent-cap protections (§1947.12) apply independently of the just-cause threshold.

In San Diego, the CoC date is verifiable through the City of San Diego Development Services Department building permit records (available online via the San Diego Permit Portal) or through the San Diego County Assessor-Recorder- Clerk property records database.

San Diego neighborhood guide: pre-2011 housing stock (AB 1482-covered)

San Diego’s oldest and densest urban neighborhoods contain significant pre-2011 — and in many cases pre-1995 — rental housing stock that is fully AB 1482-covered at approximately 8.2% for 2026. Because San Diego has no local RSO, however, there is no further local-RSO cap that would reduce these buildings’ allowable increase below the AB 1482 statewide floor.

North Park and adjacent neighborhoods

North Park is one of San Diego’s most densely rented neighborhoods, with a large stock of 1920s–1950s bungalow courts, duplexes, and three-story apartment buildings. Much of this stock is pre-1995 and fully AB 1482-covered. Adjacent neighborhoods with similar profiles:

• Hillcrest — historically significant rental market, substantial 1930s–1960s apartment stock; all covered at ~8.2%
• University Heights — 1920s–1950s housing along Park Blvd and Adams Ave; predominantly AB 1482-covered
• Normal Heights — 1940s–1960s garden apartment buildings; AB 1482-covered
• South Park — 1920s–1930s Craftsman and California bungalow neighborhoods; older pre-1995 housing stock
• Mission Hills — one of San Diego’s oldest neighborhoods, Victorian and Spanish Colonial Revival homes from 1905–1930s; significant rental stock in duplexes and small multi-family buildings
• Kensington — primarily 1920s–1930s development; many rentals in older single-family homes and small apartment buildings
• North Park commercial corridor apartments — units above retail along 30th Street and University Avenue; typically pre-1970s construction

Mid-city and inner-city neighborhoods

• City Heights — Southeastern San Diego’s most densely-rented area; older apartment stock (1950s–1980s) predominantly pre-2011; many low-income renters; AB 1482-covered
• Logan Heights / Barrio Logan — historic working-class neighborhood adjacent to the port; 1940s–1970s housing stock; AB 1482-covered
• Sherman Heights / Golden Hill — Victorian-era neighborhood near Downtown; pre-1995 housing stock; AB 1482-covered
• Linda Vista — wartime-era housing built for defense workers (1940s); largely pre-1995 stock; AB 1482-covered
• Ocean Beach (older apartments) — beachside neighborhood with a large share of 1950s–1980s rental apartments; most are AB 1482-covered; newer Ocean Beach condos may have HHBO exemptions
• Pacific Beach (older stock) — a mix of pre-2011 apartments (covered) and more recent condo-conversions; careful building-age verification required
• Point Loma (older apartments) — varied housing age; pre-1995 apartments near Liberty Station and Midway are AB 1482-covered

North County and suburban San Diego (pre-2011)

• Clairemont Mesa / Bay Park — 1960s–1980s suburban apartment complexes; AB 1482-covered
• Kearny Mesa — light-industrial and residential mix; older apartment buildings near the Balboa Avenue corridor; AB 1482-covered for pre-2011 stock
• Spring Valley / El Cajon (older areas) — San Diego County unincorporated and East County suburban rentals; 1960s–1990s apartment complexes; AB 1482-covered for pre-2011 stock
• Chula Vista (older portions) — the older western grid of Chula Vista (pre-2011 construction) is AB 1482-covered; newer eastern Chula Vista master-planned communities (Millenia, Otay Ranch) are substantially post-2011 and largely exempt

San Diego neighborhood guide: post-2011 housing (15-year exempt)

San Diego experienced a significant apartment construction wave from approximately 2012 onward, particularly in downtown San Diego and in suburban master-planned communities to the south and east. Buildings completed in or after approximately 2011 are exempt from AB 1482 under the 15-year rolling new-construction exemption and have no rent cap under any applicable ordinance (since San Diego has no local RSO). Key exempt areas:

• Downtown San Diego — East Village (Ballpark District, Petco Park area): major new apartment towers completed 2014–present; largely exempt from AB 1482
• Downtown — Little Italy: extensive new construction from 2015 onward; most new tower stock post-2011 and exempt
• Downtown — Gaslamp Quarter and Cortez Hill: mixed; some older buildings that are covered, some new towers that are exempt — building-by-building CoC verification required
• UTC (University Towne Centre): major mixed-use apartment development from 2013 onward near UCSD; large exempt cohort
• Mission Valley — new developments: former stadium site and adjacent parcels with new apartment construction post-2018; exempt
• Sorrento Valley / Torrey Hills / Del Mar Highlands: tech-corridor adjacent residential, largely 2010s construction; exempt or near-exempt boundary
• Millenia (Chula Vista): brand new planned community; post-2015 construction; fully exempt
• Otay Ranch (Chula Vista): mixed; eastern Otay Ranch villages built post-2011 are exempt; older western Otay Ranch may have some pre-2011 stock
• Santee, Santee Square developments: newer East County suburban construction; largely exempt

San Diego’s large SFR and condominium market: the HHBO notice exemption

San Diego has one of California’s largest urban condominium markets, particularly in the downtown core. During the 2000s real estate boom, hundreds of apartment buildings in East Village, Bankers Hill, Uptown, Mission Hills, and Little Italy were converted to condominiums, creating a large stock of individual-unit rental condos throughout the city.

Under California Civil Code §1947.12(d)(5)(B), a single-family home (SFR) or a condominium (or any unit in a building where each unit is alienable separately from the title to any other unit in the building) is exempt from AB 1482’s rent cap and just-cause protections if the owner has provided the written notice at commencement of tenancy that the property is a separately alienable unit and the provisions of AB 1482 do not apply. This is the HHBO notice (sometimes called the “exempt unit” notice or the “§1947.12(d) notice”).

Critical San Diego practice point: many individual condo owners who converted their units to rental properties during or after the 2000s boom served only one notice at lease commencement — the Costa-Hawkins §1954.52(a)(2) SFR/condo notice that exempts from local RSO coverage. In San Diego’s case, this notice is redundant (there is no local RSO to exempt from) but is not the correct notice to exempt from AB 1482. The separate §1947.12(d)(5)(B) notice is required to preserve the AB 1482 exemption. A condo owner who failed to serve a proper §1947.12(d)(5)(B) notice at commencement of the current tenancy cannot retroactively apply the exemption — the tenant is fully AB 1482-covered for rent cap and just-cause purposes for the duration of that tenancy.

For San Diego SFR landlords: the same principle applies. An SFR is exempt from AB 1482 only if the correct statutory notice was served at the start of the current tenancy. “I thought SFRs were automatically exempt” is not a valid defense in an unlawful-detainer proceeding where the tenant raises AB 1482 as a defense to an above-cap increase.

Military housing in San Diego and AB 1482

San Diego is home to one of the largest concentrations of military installations in the United States. Key installations within or adjacent to San Diego County:

• Naval Base San Diego (32nd Street Naval Station) — the largest naval base on the West Coast; approximately 12,000+ active-duty military personnel
• MCAS Miramar (Marine Corps Air Station Miramar) — north San Diego, approximately 6,500+ Marines and sailors
• Naval Air Station North Island — Coronado Island; significant shipboard aircraft carrier and helicopter operations
• Marine Corps Recruit Depot San Diego (MCRD) — boot camp facility in Mission Bay area
• Naval Medical Center San Diego (Balboa) — major military hospital serving active and retired personnel and dependents
• Camp Pendleton — northern San Diego County (Oceanside/Fallbrook area); the largest Marine Corps base on the West Coast; tens of thousands of Marines, sailors, and dependents who frequently reside in off-base rentals in San Diego County

Military tenants living off-base in private rental housing are subject to two parallel frameworks:

1. AB 1482: if the unit is a covered San Diego residential rental (pre-2011 building, non-exempt unit type), AB 1482’s rent cap and just-cause protections apply to military tenants exactly as they apply to civilian tenants.
2. Servicemembers Civil Relief Act (SCRA), 50 U.S.C. §§3901 et seq.: SCRA provides federal protections for active-duty service members, including §3955, which allows a service member who receives Permanent Change of Station (PCS) orders to terminate a residential lease on 30 days’ notice after delivering a copy of the orders. SCRA does not cap rent increases directly, but SCRA §3955 termination rights interact with AB 1482 just-cause requirements — a landlord cannot use AB 1482’s owner-move-in just-cause to evict a service member who has not yet received PCS orders without separately satisfying all AB 1482 just-cause elements.

Service members in San Diego with off-base housing concerns may contact Navy Legal Service Office Southwest (NLSO SW) or Marine Corps Legal Services (MCRD San Diego) for SCRA-specific guidance that complements the AB 1482 framework.

Just-cause eviction under AB 1482 §1946.2 in San Diego

AB 1482 §1946.2 imposes just-cause eviction requirements on covered San Diego residential rental units once the tenant has continuously occupied the unit for 12 months (or any member of the household has occupied the unit for 12+ months).

The 11 enumerated just causes are:

1. Non-payment of rent — tenant has failed to pay rent after a proper 3-day notice to pay or quit
2. Material lease breach — tenant has violated a material term of the lease after a 3-day notice to perform or quit
3. Nuisance, waste, unlawful use — tenant has caused or permitted a nuisance, committed waste, or used the unit for unlawful purposes
4. Criminal activity — tenant or guest convicted of or charged with criminal activity at or near the property
5. Refusal to sign renewal — tenant refuses to execute a written lease extension on similar material terms
6. Refusal to provide access — tenant refuses to allow lawful entry after proper notice
7. Unauthorized subletting — tenant sublets or assigns in violation of lease terms
8. Employee/agent relationship ended — tenancy is incident to employment and employment has ended
9. Owner-move-in (OMI) — owner or qualified family member intends to occupy as primary residence; relocation assistance of one month’s rent required for tenancies of 12+ months; re-rental prohibited for a specified period
10. Ellis Act withdrawal — owner permanently withdraws all units from the residential rental market under Cal. Gov. Code §7060 et seq.; specific noticing, payment, and right-of-return requirements apply
11. Substantial rehabilitation or demolition — under HIRD or equivalent permit requiring vacation of the unit

Because San Diego has no local RSO, §1946.2 is the exclusive just-cause framework for covered tenants. There is no San Diego Rent Board, no local right-of-return requirement beyond the Ellis Act defaults, and no local relocation assistance multiplier. Just-cause claims and unlawful detainer (UD) proceedings are filed in San Diego County Superior Court (Civil Division, 330 West Broadway, San Diego).

Notice requirements for San Diego rent increases

All San Diego residential rent increase notices are governed by California Civil Code §827(b):

• Increases below 10%: minimum 30 calendar days’ written notice (§827(b)(2)(A)).
• Increases of 10% or more: minimum 90 calendar days’ written notice (§827(b)(3)).
• Mail service: add 5 calendar days under Cal. Code Civ. Proc. §1013 for mailed notices (35 effective days for sub-10% mailed increases; 95 for 10%+ mailed increases).

San Diego’s 2026 AB 1482 cap of approximately 8.2% falls below 10%, so all standard 2026 rent increases within the AB 1482 ceiling qualify for the 30-day notice rule.

Cumulative 10% watch: The 10% notice-period threshold is measured cumulatively across all rent increases within any 12-month period. For example, if a landlord increased rent by 6% in February 2026 and now seeks to increase again by 3% in October 2026, the cumulative 12-month increase would be 9% — below 10%, so the 30-day rule still applies. But if the proposed increase were 5% instead, the cumulative 11% would trigger 90-day notice for the October notice, even though the second increase alone is less than 10%. This cumulative analysis is separate from the AB 1482 once-per-12-months frequency limit and must be conducted independently.

Required disclosures: AB 1482 §1947.13 requires San Diego landlords in covered multi-unit buildings to include a tenant-rights disclosure with any rent increase notice and at commencement of tenancy. The disclosure must inform tenants of the AB 1482 cap and just-cause protections. Failure to include the required disclosure does not void the notice but may subject the landlord to §1947.13 penalties.

Penalties for violating AB 1482’s rent cap in San Diego

An unlawful rent increase — one that exceeds the ~8.2% AB 1482 cap for covered San Diego units — is remediable under Cal. Civ. Code §1947.12(h). Because San Diego has no local rent board, all enforcement is through civil litigation:

• Rent rollback: a court may order the rent reduced to the lawful AB 1482 rate
• Restitution of overcharges: the tenant is entitled to a refund of all unlawfully collected rent above the cap, with 10% per annum statutory interest under Cal. Civ. Code §3289(b)
• Treble damages: for willful violations, up to three times the unlawfully collected rent (§1947.12(h)(3)), minimum $250 per violation
• Attorney fees: to a prevailing tenant under §1947.12(i), in addition to treble damages
• Affirmative defense in eviction proceedings: an above-cap increase is unenforceable as to the over-cap portion; a tenant served with a UD for non-payment of an above-cap amount may raise the AB 1482 violation as a complete defense

The limitations period is three years under Cal. Code Civ. Proc. §338. Claims may be filed at San Diego County Superior Court (Hall of Justice, 330 West Broadway, San Diego 92101) or, for claims under the small claims threshold, at San Diego County Small Claims Court.

San Diego compared to California cities with local RSOs

The absence of a San Diego local RSO creates a stark contrast with nearby and comparable California cities:

• Los Angeles (LAMC §151.02 RSO): pre-October 1, 1978 buildings in LA are subject to the LA RSO at approximately 3% for 2026 — 5.2 percentage points lower than San Diego’s ~8.2% AB 1482 cap. A 1970 building in San Diego allows a ~$164/month increase on a $2,000 rent; a comparable 1970 building in Los Angeles is capped at ~$60/month.
• San Francisco (SF Admin Code §37.2(p)): pre-June 13, 1979 SF buildings are RSO-covered at approximately 1.6% for 2026 — a 6.6pp gap vs. San Diego.
• Oakland (OMC §8.22.030 RAP): pre-December 31, 1982 Oakland buildings are covered by the Oakland Rent Adjustment Program at approximately 1.7% for 2026 (March-to-March CPI measurement period) — a 6.5pp gap.
• Santa Monica (SMMC §4.52): one of California’s strictest RSOs; 2026 AGA approximately 3%. A 1975 Santa Monica building is capped at 3%; the same building in San Diego is capped at 8.2% under AB 1482.
• Orange County: all 34 OC cities, including Irvine, Anaheim, and Santa Ana, are also AB 1482-only with ~8% (using LA MSA CPI at ~3.0% rather than SD MSA at ~3.2%). San Diego’s ~8.2% is ~0.2pp higher than OC cities.

The practical implication: a landlord with a pre-1978 building in San Diego operates under a much more permissive rent-cap framework than a comparable landlord in Los Angeles, San Francisco, or Oakland. For San Diego tenants in older buildings, the absence of a local RSO means there is no recourse to a local rent board, no hearing process for above-AGA petitions, and no local banked-increase limits — only the statewide AB 1482 ceiling and civil court enforcement.
