The maximum rent increase in San Diego is 8.2% — calculated as 5% plus the San Diego County Consumer Price Index change of 3.2% — effective August 1, 2026 through July 31, 2027. This cap applies to most residential rental properties built before January 1, 2010 under California AB 1482. Getting it wrong costs more than the increase is worth.
Most San Diego landlords who ask "how much can I raise rent" are really asking three separate questions: what is the legal maximum, does my property qualify, and what is the correct process for issuing the notice. This guide answers all three — with specific calculations for every rent level from $1,800 to $5,500/month, city-by-city compliance requirements, and the most common errors that void an otherwise valid rent increase.
Quick Answer
How much can I raise rent in San Diego? The maximum allowable rent increase is 8.2% for covered properties under California AB 1482 — 5% plus San Diego County CPI of 3.2% — effective August 1, 2026 through July 31, 2027.
What is the AB 1482 rent increase cap? The AB 1482 rent increase cap is a California statutory limit — under Civil Code Section 1947.12 — on how much a landlord may increase rent in any 12-month period for covered residential rental properties. The cap equals 5% plus the local CPI, not to exceed 10% total. For San Diego County, that is 8.2%.
Does the rent cap apply to my San Diego rental? AB 1482 covers most San Diego County rental properties built before January 1, 2010. Single-family homes and condos not owned by a corporation, REIT, or LLC may be exempt — but only if the correct written exemption notice was included in the lease at signing. If it was not, the property is covered for that tenancy regardless of property type.
How many rent increases per year in California? AB 1482 permits a maximum of two rent increases in any 12-month period — but the combined total cannot exceed 8.2%. A single annual increase is simpler and reduces documentation risk.
How much notice is required for a rent increase in California? California law requires 30 days written notice for increases of 10% or less. Because the AB 1482 cap is 8.2%, 30 days written notice is the applicable standard for all lawful increases on covered properties. If notice is mailed, add 5 calendar days.
The most expensive rent increase errors in San Diego are not mathematical — they are procedural. A landlord who applies the correct 8.2% increase but serves notice by text message, or applies it to a lease missing the AB 1482 exemption notice, has issued a non-compliant notice regardless of the math. The calculation is the easy part.
TL;DR
- Maximum rent increase, San Diego County: 8.2%, August 1, 2026 through July 31, 2027
- Formula: 5% + San Diego County CPI (3.2%) — verify the current figure at BLS.gov before every notice
- Two increases permitted per 12 months — cumulative total cannot exceed the annual cap
- Exempt from cap: post-2010 construction, SFH/condos with correct notice at signing, certain affordable housing
- Notice required: 30 days written (add 5 days if mailed)
- Most of San Diego County — La Mesa, El Cajon, Santee, Escondido and others — has no local ordinance; state AB 1482 is the whole rulebook
- City of San Diego and Chula Vista add just-cause and relocation requirements on top of state law
- The cap resets again August 1, 2027 — do not carry 8.2% past that date without re-verifying
San Diego Rent Increase: Key Numbers
| Maximum rent increase | 8.2%, Aug 1, 2026 – Jul 31, 2027 |
| Formula | 5% + San Diego County CPI (3.2%) |
| CPI source | BLS.gov — San Diego–Carlsbad CPI-U, 12 months ending March 2026 |
| Next cap reset | August 1, 2027 |
| Permitted increases per 12 months | Maximum 2 — cumulative total cannot exceed 8.2% |
| Notice required | 30 days written (90 days if increase exceeds 10%) |
| Governing statute | California Civil Code Section 1947.12 |
| Properties covered | Most residential rentals built before January 1, 2010 |
| Properties potentially exempt | Post-2010 construction, SFH/condos with correct notice, certain affordable housing |
If you are working from an older figure: the San Diego County cap was 8.8% through July 31, 2026. It dropped to 8.2% on August 1, 2026. Any notice served now takes effect under the 8.2% cap — a notice calculated at 8.8% exceeds the legal limit.
San Diego Rent Increase Calculator: Maximum Allowable by Rent Level
The maximum allowable rent increase for a covered San Diego property is 8.2% of the current monthly rent. The table below calculates the maximum increase, new rent, and annual revenue gain for common San Diego rent levels. All figures assume one increase applied in the 12-month period.
| Current Rent | Max Increase (8.2%) | New Monthly Rent | Annual Revenue Gain |
|---|---|---|---|
| $1,800 | $147 | $1,947 | $1,764 |
| $2,000 | $164 | $2,164 | $1,968 |
| $2,200 | $180 | $2,380 | $2,160 |
| $2,400 | $196 | $2,596 | $2,352 |
| $2,600 | $213 | $2,813 | $2,556 |
| $2,800 | $229 | $3,029 | $2,748 |
| $3,000 | $246 | $3,246 | $2,952 |
| $3,200 | $262 | $3,462 | $3,144 |
| $3,500 | $287 | $3,787 | $3,444 |
| $3,800 | $311 | $4,111 | $3,732 |

| $4,800 | $393 | $5,193 | $4,716 |
| $5,500 | $451 | $5,951 | $5,412 |
Formula: Current Rent × 0.082 = Maximum Increase. Round down to the nearest dollar. Two increases in 12 months are permitted, but combined they cannot exceed Current Rent × 0.082.

AB 1482 coverage is a property-level legal status that determines whether the 8.2% rent cap and Just Cause eviction requirements apply. Coverage is the default for most San Diego County properties built before January 1, 2010. Exemption requires affirmative action at the lease signing — and cannot be established retroactively.
| Property Type | AB 1482 Covered? | Condition for Exemption |
|---|---|---|
| Apartment built before Jan 1, 2010 | Yes | No exemption available |
| Apartment built after Jan 1, 2010 | Not covered | Exempt by statute — no action required |
| SFH/condo — individual owner, no corporate entity | Exempt IF notice in lease at signing | Correct written notice at signing |
| SFH/condo — corporate, REIT, or LLC owned | Yes | No ownership-based exemption available |
| SFH/condo — notice missing at signing | Yes — covered for full tenancy | Cannot be corrected retroactively |
| Subsidized affordable housing | Typically exempt | Verify with housing authority |
| Owner-occupied duplex | Exempt if owner occupies and notice served | Owner must occupy one unit at time of tenancy |

Rent Increase Requirements by City: San Diego County
The 8.2% cap is the same countywide — it is set by state law, and no San Diego County city adds its own rent cap. What varies is everything around the increase: just-cause requirements, relocation assistance, and city notification. Three jurisdictions add rules: the City of San Diego (San Diego Municipal Code §§98.0701–98.0709), which includes neighborhoods like Mission Valley, North Park and South Park; Chula Vista (Chula Vista Municipal Code Chapter 9.65); and Imperial Beach (Imperial Beach Municipal Code Chapter 9.90, effective March 22, 2025). Everywhere else in the county, state AB 1482 is the whole rulebook. Verify your property's jurisdiction before relying on either — city limits do not always match mailing addresses.
| City / Area | Rent Cap | Local Ordinance? | What It Adds |
|---|---|---|---|
| City of San Diego | 8.2% | Yes — SDMC 98.0701–98.0709 | Just cause from day one; 2 months relocation for no-fault (3 if 62+ or disabled); Housing Commission notice |
| Chula Vista | 8.2% | Yes — CVMC 9.65 | Just cause; relocation for no-fault; City notice within 3 business days; $40/sq ft remodel minimum |
| Imperial Beach | 8.2% | Yes — IBMC 9.90 | Just cause; stricter substantial-remodel definition; City filing within 3 business days; extra relocation at 15+ unit properties |
| La Mesa | 8.2% | No | State AB 1482 only |
| El Cajon | 8.2% | No | State AB 1482 only |
| National City | 8.2% | No | State AB 1482 only |
| Santee, Lakeside | 8.2% | No | State AB 1482 only |
| Lemon Grove, Spring Valley | 8.2% | No | State AB 1482 only |
| Escondido, Vista, San Marcos | 8.2% | No | State AB 1482 only |
| Oceanside, Carlsbad, Encinitas | 8.2% | No | State AB 1482 only |
Local ordinances change. Confirm current requirements with the city before serving any notice on a property in San Diego or Chula Vista.

A valid San Diego rent increase requires completing six steps in sequence. An error at any step — wrong CPI figure, defective delivery method, missing exemption documentation — may void the increase and require restarting the process with a new 30-day notice period.
Step 1 — Confirm AB 1482 coverage status. Verify whether your property is covered or exempt. If a single-family home or condo, confirm the exemption notice was in the current lease at signing.
Step 2 — Verify the current cap at BLS.gov. The current cap is 8.2%, effective through July 31, 2027. Do not use a figure from a prior year or a secondary source — the cap resets every August 1.
Step 3 — Calculate the maximum increase. Current rent × 0.082, rounded down. You may increase by less. Never more.
Step 4 — Check the 12-month increase history. If you issued any increase in the past 12 months, the cumulative total cannot exceed the annual cap for that period.
Step 5 — Deliver written notice. Minimum 30 days before the effective date. First class mail or personal service — text and email are generally insufficient. Add 5 days if mailing.
Step 6 — Document the notice. Retain a copy and proof of delivery method and date. A paper trail protects the increase if disputed.
Most Common Rent Increase Errors in San Diego
The most expensive rent increase errors in San Diego are not mathematical — they are procedural. A correct 8.2% calculation does not protect a non-compliant notice. The six errors below account for the majority of disputed rent increases in San Diego County.
Error 1 — Using last year's cap. This is the live one right now. The cap dropped from 8.8% to 8.2% on August 1, 2026 — a notice calculated at 8.8% today exceeds the legal limit. Verify at BLS.gov before every notice, not just when you think the cap has changed.
Error 2 — Applying the increase to a non-compliant lease. A correct calculation on a non-compliant lease is still a disputed increase — confirm the required AB 1482 disclosures are in the current lease before issuing any notice.
Error 3 — Serving notice by text or email. A text message is not a written notice under California law — it is an undelivered notice, and the 30-day clock never started.
Error 4 — Missing the 30-day minimum. An increase that takes effect in under 30 days is void — the process restarts, the effective date resets, and the income from that delay is gone.
Error 5 — Exceeding the cumulative 12-month cap. Two increases are permitted per year — but if the first was 5%, the second cannot exceed the remaining balance (3.2%), not a fresh 8.2%.
Error 6 — Missing local requirements in San Diego, Chula Vista, or Imperial Beach. The state rules are the floor, not the ceiling. In the City of San Diego, just cause applies from day one and no-fault terminations require Housing Commission notice. In Chula Vista, a no-fault notice is invalid unless the City is notified within three business days. In Imperial Beach, any termination notice must be filed with the City within three business days.
What a Failed Notice Actually Looks Like
The situation: La Mesa landlord. 2BR condo renting for $2,600/month, built 1988, covered under AB 1482. The owner texts the tenant on March 1 that rent is going up $213 effective April 1.
The math is right. $2,600 × 0.082 = $213. Thirty-one days of notice clears the 30-day minimum. On paper this looks like a valid increase.
The delivery is not. A text message is not written notice under California law. The 30-day clock never started, so the increase has no effective date — and the correct calculation does not save it.
Result: The tenant declines to pay the increase and is entitled to. The owner restarts — new written notice by mail or personal delivery, 35 days (30 plus 5 for mailing), then the increase applies. Roughly five to six weeks lost, at $213/month.
The fix: First class mail or personal delivery. Document the delivery date. Keep a copy. Fifteen minutes, no cost.
The Hidden Cost of Not Raising Rent
Under AB 1482, the rent you set at lease signing is not just this year's price — it is the base every future increase is calculated from. Start $200/month below market and the 8.2% cap cannot close that gap quickly, because each year's increase is a percentage of a number that was already too low. The longer the tenancy, the longer the gap persists.
| Underpricing Gap | Annual Income Loss | Loss Over a 3-Year Tenancy |
|---|---|---|
| $100/month below market | $1,200 | $3,600 |
| $200/month below market | $2,400 | $7,200 |
| $300/month below market | $3,600 | $10,800 |
| $500/month below market | $6,000 | $18,000 |
Straight-line calculation of the rent difference. Does not account for the compounding effect of a suppressed base on subsequent annual increases, which makes the true gap larger.
Most San Diego landlords are not undercharging because they are generous — they are undercharging because they never re-benchmarked after a long-term tenancy ended. Get a current rent benchmark before the next lease signing at RMG's free rental analysis.
When Not to Raise Rent
The legal maximum is not always the right number. There are situations where taking the full increase costs more than it earns — and a manager worth paying will tell you so.
There is an unresolved maintenance issue. Raising rent while a reported leak or broken appliance is outstanding hands the tenant both a legal argument and a negotiating position. Close the repair first.
The tenant is good and the increase is small relative to turnover cost. A single month of vacancy on a $3,000 unit is $3,000, before make-ready costs. A $246/month increase takes a full year to earn that back — so if the increase is what tips a reliable long-term tenant into leaving, the math does not work. Retention frequently beats the maximum.
The tenancy is already unstable. A tenant who has recently lost a job or gone through a separation is a vacancy risk at any rent level. Timing an increase against that accelerates the departure you were hoping to avoid.
You are near an insurance renewal or refinance. A vacancy that lands at the same moment a lender or insurer is looking at the property creates exposure on both sides. Time increases against the property's financial calendar, not only the lease anniversary.
You are already within a few percent of market. A tenant paying $2,600 on a $2,700 market-rate unit is close enough that pushing for the last $100 risks a $2,700 vacancy. That is not generosity — it is arithmetic.
Frequently Asked Questions
How much can I raise rent in San Diego?
The maximum rent increase in San Diego County is 8.2% for covered properties under California AB 1482, effective August 1, 2026 through July 31, 2027. On a $2,800/month unit that is $229/month. On a $3,200/month unit that is $262/month. Use the calculator table above for your specific rent level.
What is the AB 1482 rent cap for San Diego?
8.2% — calculated as 5% plus the San Diego County CPI change of 3.2%, using San Diego–Carlsbad CPI-U data for the 12 months ending March 2026. It applies to covered properties under Civil Code Section 1947.12 from August 1, 2026 through July 31, 2027.
Does La Mesa or El Cajon have rent control?
No. Neither city has a local rent or just-cause ordinance — both are governed by state AB 1482 alone, at the same 8.2% cap that applies countywide. Within San Diego County, only the City of San Diego, Chula Vista, and Imperial Beach add local tenant-protection rules on top of state law.
Does my San Diego rental qualify for the AB 1482 exemption?
A San Diego rental may qualify for the ownership-based exemption if it is a single-family home or condominium not owned by a corporation, REIT, or LLC — and the correct written exemption notice was included in the lease at signing. Missing notice at signing means covered for that tenancy, and it cannot be corrected retroactively. See the full AB 1482 exemption analysis.
How much notice is required for a rent increase in California?
30 days written notice for increases of 10% or less, and 90 days for increases above 10%. Because the AB 1482 cap is 8.2%, 30 days is the applicable standard for covered properties. Add 5 calendar days if delivering by first class mail.
Can I raise rent more than 8.2% if my property is exempt from AB 1482?
Yes — a validly exempt property has no statutory cap under state law. The required notice periods still apply, and the San Diego Tenant Protection Ordinance still governs terminations for City of San Diego rentals regardless of AB 1482 exemption status. Confirm exemption validity before issuing any above-cap increase.
Can I raise rent twice in one year in California?
Yes — up to two increases per 12-month period, but the combined total cannot exceed 8.2%. Two increases of 4.1% each are permitted. A single annual increase is operationally simpler and reduces dispute risk.
When does the AB 1482 rent cap reset?
Every August 1. The current cap of 8.2% runs through July 31, 2027. Any increase with an effective date on or after August 1, 2027 must use the new figure — verify at BLS.gov before issuing notice.
What happens if I raise rent more than AB 1482 allows?
It is a violation of Civil Code Section 1947.12. The tenant may refuse the excess, and the landlord may be liable for actual damages, punitive damages, and attorney fees. Only the amount above the cap is unenforceable — not the entire increase.

Rent cap figures reflect California Civil Code Section 1947.12 and BLS San Diego–Carlsbad CPI-U data for the 12 months ending March 2026. The 8.2% cap applies to San Diego County for increases effective August 1, 2026 through July 31, 2027. Local ordinance references reflect San Diego Municipal Code §§98.0701–98.0709, Chula Vista Municipal Code Chapter 9.65, and Imperial Beach Municipal Code Chapter 9.90 (effective March 22, 2025). This guide is for informational purposes only and does not constitute legal advice.
The 8.2% cap is the easy part. The hard part is knowing whether your property is covered, whether your lease is compliant, whether your notice method is valid, and whether the rent you are increasing from already reflects current market value.
In San Diego, rent increase authority is not limited by the cap — it is limited by the documentation and process behind it.
