Lemon Grove and Spring Valley sit side by side in Southeast San Diego County, share the same compliance framework — state AB 1482, no local ordinance — and are two of the county's most affordable rental markets. But their 2026 numbers are moving differently: Lemon Grove is rising broadly (average rent up 9.6% year over year), while Spring Valley is split, with its northern ZIP softening and its southern corridor surging. If you own in either, the pricing and compliance moves are similar; the market timing is not. This guide covers both.
Both cities are governed entirely by California's statewide Tenant Protection Act (AB 1482) — neither has a local tenant-protection ordinance, so the state notice form is sufficient and there's no city-specific addendum to layer on. That's a genuine simplification versus the City of San Diego or Chula Vista. It does not, however, reduce the documentation obligations under AB 1482, AB 12, AB 2801, AB 2493, and AB 628. RMG provides flat-fee San Diego property management across both communities.
For deeper, city-specific detail, see our dedicated Spring Valley property management guide and our Lemon Grove property management page. This overview covers what owners in both markets need for 2026.
The AB 1482 rent cap is 8.8% through July 31, 2026, then 8.2% for August 1, 2026 through July 31, 2027 (5% plus the San Diego regional CPI, which reset from 3.8% to 3.2%). It applies to covered properties in both Lemon Grove and Spring Valley — and because both markets are overwhelmingly pre-2010 housing, that's most of them.
Quick Answers (Lemon Grove & Spring Valley, 2026)
What is the average rent in Lemon Grove in 2026? $2,860/month, up 9.6% over the last 12 months (RentCast, July 2026). By type: studio ~$1,450; 1BR ~$2,110; 2BR ~$3,050; 3BR ~$3,480; 4BR ~$3,660.
What is the average rent in Spring Valley in 2026? It splits by ZIP: 91977 (north) averages $2,670/month (down 8.2%); 91978 (south/Jamacha corridor) averages $3,550/month (up 18.7%), on larger single-family homes (RentCast, July 2026).
Do Lemon Grove or Spring Valley have rent control? Neither has a local ordinance. Both are governed by state AB 1482 only — capping increases at 8.8% through July 31, 2026, then 8.2% for the Aug 1, 2026–Jul 31, 2027 window, on covered properties.
What's the difference between the two for landlords? Lemon Grove is an incorporated city (ZIP 91945) with trolley access and steady, broad-based rent growth. Spring Valley is unincorporated with two very different ZIPs. Both follow state law only, so compliance is identical; the market timing differs.
What does property management cost here? Most managers charge 8–10% of rent plus leasing fees. RMG charges a flat $199/month with no leasing or renewal fees — the most controllable variable in these stable-demand markets.

Lemon Grove (ZIP 91945)
Lemon Grove — the small incorporated city known for its "Best Climate on Earth" motto and giant lemon statue — is one of San Diego County's most affordable urban rental markets, with trolley access to downtown and steady renter demand. In 2026 it's showing broad-based rent growth: the average is up 9.6% over the year, with most unit types rising. Unlike neighboring Spring Valley, it's a single ZIP (91945) with more uniform pricing.

Lemon Grove Market (RentCast, July 2026)
Average rent: $2,860/month, +9.6% over 12 months
Studio: ~$1,450 (+5.8%) | 1BR: ~$2,110 (+6%)
2BR: ~$3,050 (+14.7%) | 3BR: ~$3,480 (+1.2%)
4BR: ~$3,660 (+25.8% — a large year-over-year gain on a smaller, more volatile segment; treat as directional)
Range: $1,450 to $8,888 across the market
The Lemon Grove story is broad-based strength: unlike markets carried by a single segment, most unit types rose here, with 2BR (+14.7%) the standout among the reliable, higher-volume categories. For owners, that means less risk of mispricing by unit type — but the AB 1482 cap still applies, so a home set below market at signing stays behind until turnover. Deeper detail and a free pricing analysis are on the Lemon Grove page.
Spring Valley (ZIPs 91977 & 91978)
Spring Valley is unincorporated San Diego County — no city government, no local ordinance, state AB 1482 only. It's also two markets in one: the dense northern core (91977) and the larger-lot southern Jamacha/Sweetwater Springs corridor (91978), which in 2026 are moving in opposite directions. That split makes pricing to the correct ZIP the single most valuable decision a Spring Valley owner makes.

Spring Valley Market (RentCast, July 2026)
91977 (north/core): average $2,670/month, down 8.2% — denser, apartment-heavy, more affordable. Studio ~$1,600; 1BR ~$1,750; 2BR ~$2,270; 3BR ~$3,650; 4BR ~$4,130.
91978 (south/Jamacha corridor): average $3,550/month, up 18.7% — larger single-family homes, premium corridor. 1BR ~$2,200; 2BR ~$3,300; 3BR ~$3,480; 4BR ~$4,620. Thin inventory (about a dozen active listings), so per-bedroom figures are volatile — treat as directional.
The Spring Valley story is divergence: the two ZIPs are moving opposite directions, so pricing a Jamacha-corridor home off the softer north-side average leaves real money on the table — and the cap locks that gap in until turnover. Full ZIP-by-ZIP detail, housing-stock risk analysis, and a free pricing check are in the dedicated Spring Valley guide.
2026 Compliance: The Same Rules in Both Cities
Because neither city has a local ordinance, the compliance picture is identical — state law only. The state AB 1482 notice form is sufficient in both; no city-specific addendum is required. The most common failure isn't misreading the rules — it's treating simpler compliance as an excuse for looser documentation.
AB 1482 — rent cap & just cause. 8.8% through July 31, 2026, then 8.2% for the Aug 1, 2026–Jul 31, 2027 window; just cause required after 12 months. The exemption notice must be in the lease at signing, or a qualifying single-family home is treated as covered.
AB 12 — deposit cap. Since July 1, 2024, most landlords may collect no more than one month's rent (Civil Code §1950.5), with a small-landlord exception of up to two months.
AB 2801 — deposit photos. Timestamped photos before move-in, after move-out, and after any repair/cleaning for which a deduction is claimed; itemized statement within 21 days.
AB 628 — appliances (eff. Jan 1, 2026). Leases signed, renewed, or amended on/after Jan 1, 2026 must include a working stove and refrigerator (Civil Code §1941.1).
AB 2747 — rent reporting. Landlords must offer tenants the option to report rent to credit bureaus, at signing and annually.
AB 2493 — screening & fees. Written screening criteria before marketing; fees reflect actual cost and are refunded to applicants not offered a tenancy unless retained under the statute.
Notice timing under Civil Code §827: 30 days for an increase of 10% or less, 90 days for over 10% (add 5 days if mailed). See the full AB 1482 exemption guide and the rent-control ordinance map.
Why Owners in Both Markets Use Professional Management
In stable-demand Southeast County markets where vacancy risk is low, the management fee is the most controllable variable in your annual return. Most managers charge 8–10% of collected rent plus a leasing fee of up to one month's rent at every turnover. RMG charges a flat $199/month — no percentage, no leasing fee, no renewal fee, no maintenance markup — and it stays flat as rent rises.
