Commercial Real Estate Financing in California: The Complete Guide

California remains the second-largest commercial real estate market in the United States by dollar volume, behind only New York. It is also the most regulated. Financing CRE in California requires navigating Proposition 13 tax dynamics, rent control under Costa-Hawkins and AB 1482, seismic retrofit requirements, and entitlement timelines that routinely kill deals before they reach closing.

Sponsors who execute well in California accept the friction and structure around it. Sponsors who assume Sun Belt mechanics will translate lose equity in places they did not expect to lose it. The lender pool knows this. Underwriting is accordingly more rigorous on California assets than on peer-quality deals in Texas or Florida.

Why California Still Matters

Despite the dominant narrative of outbound migration, California remains a top-tier CRE market for structural reasons:

• Economy scale. Fifth-largest in the world if measured as a country. The diversification of tech (Bay Area), entertainment (LA), biotech (San Diego), and logistics (Inland Empire) provides demand across every asset class.
• Supply constraint. Entitlement difficulty is a feature, not a bug, for existing owners. New supply is slow and expensive, which protects rent growth and pricing on existing stock.
• International capital. California is the top US destination for Asian capital flows into CRE, particularly in the Bay Area and LA. This sustains pricing on trophy assets.
• Industrial strength. The Inland Empire has become the largest industrial market in the country, driven by the ports of Los Angeles and Long Beach. Lender appetite for industrial California is among the highest nationally.

The Four Major California Markets

Los Angeles

LA is the largest and most segmented market in California. West LA, Santa Monica, and Beverly Hills command the highest pricing in the state. Downtown LA continues to bifurcate between trophy Class A and older Class B/C office that is restructuring or converting. Multifamily in rent-controlled submarkets (per Costa-Hawkins) follows its own pricing logic.

The LA industrial submarket near the ports (Carson, Wilmington, Long Beach) is one of the tightest industrial markets in the country. Multifamily in the South Bay and San Fernando Valley trades actively at accessible cap rates. Specialty medical office and life sciences in Culver City and Santa Monica command institutional pricing.

San Francisco Bay Area

The Bay Area reshaped post-2020 more than any major US CRE market. San Francisco office remains structurally challenged — vacancy stuck at elevated levels, tenant demand concentrated in AI-adjacent tenancies, conversion and obsolescence themes dominant. Silicon Valley and Peninsula office are healthier but differentiated by submarket.

Multifamily in the Bay Area is strong on fundamentals — extreme supply constraint — but underwriting is scrutinized given the rent control regime and tenant protection framework. Industrial in the East Bay and South Bay remains in high demand. Life sciences (Mission Bay, Peninsula) has moderated from 2021 peaks but retains institutional interest.

San Diego

San Diego is the most consistent California metro. Strong military and biotech demand drivers, less supply overhang than peers, reasonable entitlement timelines relative to Bay Area and LA. Multifamily value-add and medical office are the most active segments. Life sciences cluster in Torrey Pines and Sorrento Valley continues to attract specialized lenders.

Inland Empire (Riverside / San Bernardino)

The Inland Empire is the largest industrial submarket in the United States by square footage and one of the most institutional. E-commerce tenant demand built around the ports of LA and Long Beach drives the entire market. Cap rates compressed aggressively from 2019-2022 and have recalibrated, but lender appetite remains strong on well-located Class A industrial.

Secondary Markets

Sacramento, Fresno, Bakersfield, the Central Coast, and Redding/North State CRE markets trade at materially higher cap rates than coastal California (7% to 9% on stabilized multifamily vs 4.5% to 5.5% in the Bay Area). Lender coverage is thinner and more relationship-based. These markets reward sponsors who have local broker and bank relationships.

Proposition 13 — The Tax Structure Nobody Understands Until They Lose Money

Proposition 13, passed in 1978, fundamentally shapes California CRE underwriting. The core mechanics:

• Property tax is assessed at 1% of purchase priceplus voter-approved local bonds (typically bringing effective rates to 1.10% to 1.25% of purchase price).
• Reassessment caps at 2% per year while the property remains under the same ownership.
• Sale triggers full reassessment to current market value at the new purchase price.

The underwriting implication is subtle but enormous: an existing owner who has held a property for 15 years may be paying taxes on an assessed value 30% to 50% below market. When a new buyer acquires the property, their tax bill often doubles or triples overnight. The seller’s trailing twelve months NOI becomes meaningless for the buyer.

Experienced California brokers (and lenders) always underwrite to the post-acquisition reassessment, not the seller’s tax bill. Sponsors who model current owner taxes into their pro forma lose debt capacity and often equity when the real numbers surface during underwriting.

Rent Control: Costa-Hawkins and AB 1482

California has two layers of rent control relevant to CRE underwriting:

Costa-Hawkins Rental Housing Act (1995)

Governs local rent control ordinances in cities that have them (LA, San Francisco, Santa Monica, West Hollywood, Oakland, Berkeley, San Jose, and others). Key protections for property owners:

• Rent control does not apply to buildings constructed after February 1, 1995 (newer construction is exempt)
• Single-family homes and most condos are exempt
• Vacancy decontrol applies — landlord can reset rent to market on voluntary vacancy

The November 2024 Proposition 33 to repeal Costa-Hawkins failed at the ballot for the third time. Costa-Hawkins protections remain in place for now, though the political pressure continues.

AB 1482 — Statewide Rent Cap (2019)

Applies to multifamily buildings 15+ years old statewide that are not covered by stronger local ordinances. Caps annual rent increases at 5% plus CPI (maximum 10%). Includes just-cause eviction requirements.

Practical implications for underwriting: on value-add deals involving rent-repositioning, model rent growth conservatively. The 5% + CPI cap is not a floor for rent growth — it is a ceiling. Legal burn-off of over-market tenants through vacancy decontrol still works under Costa-Hawkins, but the timeline is longer and more uncertain than sponsors assume.

Seismic Retrofit Requirements

California enforces seismic retrofit ordinances that directly impact CRE underwriting, particularly in Los Angeles and San Francisco:

• LA Soft-Story Ordinance — requires structural retrofitting of multi-story wood-frame buildings with a vulnerable first story. Compliance deadlines for buildings constructed before 1978 have rolled out in phases since 2015.
• LA Non-Ductile Concrete Ordinance — targets pre-1976 concrete buildings with non-ductile frames. Extended compliance timeline but costs are significant.
• San Francisco Soft-Story Program — substantially complete by now, but properties with outstanding notices of non-compliance cannot transfer cleanly.

Lenders will not finance non-compliant buildings. Sponsors acquiring older California multifamily need to verify retrofit status at LOI, budget for compliance costs (often $15K to $30K per unit for soft-story retrofit), and confirm the timing fits the business plan.

Entitlement Reality

Ground-up development in California is the longest-tailed construction process in any major US market. Entitlement timelines in coastal California (LA, Bay Area, San Diego) routinely run three to five years for meaningful multifamily or mixed-use projects. CEQA review, coastal commission sign-off on coastal properties, local design review, and political dynamics all add time.

For construction financing, this means:

• Development-to-stabilization timelines of seven to ten years are realistic, not worst-case
• Carry cost modeling during entitlement and construction dominates project economics
• Pre-development bridge capital is its own financing category — sponsors typically fund entitlement out of equity or specialty pre-dev debt
• SB 330 and similar streamlining legislation have helped on qualifying affordable projects but have not fundamentally changed market-rate timelines

The California Lender Landscape

California CRE debt is deep and segmented:

• Agency multifamily — Fannie and Freddie are highly active, particularly on stabilized Class A and B+ properties. Underwriting accounts for rent control where applicable.
• Life companies — very active on trophy assets in coastal California at competitive pricing. MetLife, Nuveen, PGIM, and others have dedicated West Coast platforms.
• Regional banks — meaningfully more cautious post-2023 bank stresses. Pacific Premier, City National, East West Bank, and Cathay General remain active but more selective.
• Debt funds — dominate bridge and construction financing. West Coast-focused shops compete with national players.
• Private / hard money — vibrant California market, particularly for fix-and-flip and smaller bridge deals outside the main metros.

Common Sponsor Mistakes on California Deals

• Underwriting seller’s Prop 13 tax basis into the pro forma. Reassessment will make the real numbers materially different. Always model post-acquisition taxes.
• Assuming rent control does not apply. Building age, city jurisdiction, and exemption status all matter. Confirm with California counsel before committing.
• Modeling entitlement timelines from other states.A 12-month entitlement in Texas is a 30-36 month entitlement in coastal California. Carry costs and capital market risk over that period are material.
• Missing the seismic retrofit flag. Non-compliant buildings do not finance. Verify status before LOI, not at due diligence.

How Passy Capital Places California Deals

California CRE financing rewards specialization. Our approach is to structure around the constraints that are unique to this market — post-acquisition tax reassessment, rent-control-aware sizing, seismic compliance verification, and realistic entitlement modeling on ground-up projects.

On the lender side, we work with agency multifamily, life companies, debt funds, and regional banks active in California. Matching the deal to the lender pool that fits takes deep familiarity with California-specific underwriting standards — there is no universal CRE debt product that clears the friction the way it does in Sun Belt markets.
