California Construction Loan Size Tiers & Conforming Limits

Conforming vs jumbo thresholds by county, and how loan size affects your options.

By Shane BoothResearched 2026-04-08high confidence

California's 2025 conforming loan limit is $806,500 (baseline) and $1,209,750 (high-cost ceiling, applicable in 9 counties including SF Bay Area, LA, and Orange County). Construction and renovation loans fall into six practical tiers: under $100K (personal/unsecured or HELOC), $100K-$500K (conforming with broadest product availability), $500K-$1M (conforming in most populated CA counties), $1M-$2M (jumbo in most cases, conforming only up to $1,209,750 in high-cost counties), $2M-$3M (jumbo), and $3M+ (super jumbo/private). Renovation loans (FHA 203k, HomeStyle, CHOICERenovation) offer the highest LTVs (up to 97%) and lowest credit score requirements (580-620) but are capped at conforming limits. True construction-to-permanent loans require higher credit scores (680+) and larger down payments (20%+). California's high property values push the majority of metro-area construction loans into high-balance conforming or jumbo territory. The state's dual DRE/CFL licensing framework supports the nation's highest density of private and hard money lenders, providing options for borrowers who cannot qualify for conventional products. CalHFA does not offer standalone construction loans. Seismic retrofit mandates in LA and SF, Title 24 energy code requirements, and extended permitting timelines (3-6+ months) materially affect construction loan budgets and schedules.

Key Facts

Decision Rules

If: Renovation project under $75,000 AND borrower has good credit (620+) AND borrower wants to avoid using home as collateral

Then: Route to personal unsecured loan. Fastest funding (1-5 days), no appraisal required, but highest interest rates (7-36%). Best for cosmetic updates. Alternative: HELOC if borrower has equity and wants lower rate.

If: Renovation project under $75,000 AND borrower purchasing a home simultaneously AND credit score 580+

Then: Route to FHA 203(k) Limited/Streamline. Allows financing renovation costs into the purchase mortgage at low rates with 3.5% down. No structural work permitted. No HUD consultant required.

If: Renovation or construction loan $100K-$500K AND borrower credit score 620+ AND primary residence

Then: Route to conforming renovation products first: Fannie Mae HomeStyle (up to 97% LTV) or Freddie Mac CHOICERenovation (up to 97% LTV) for renovations; FHA 203(k) Standard for purchase-plus-renovation (96.5% LTV, 580+ credit). For ground-up construction, route to construction-to-permanent one-close loan. All offer the best rates and highest LTVs in this tier.

If: Loan amount $500K-$1M AND property in one of California's 9 high-cost counties (SF, LA, Orange, Alameda, Contra Costa, Marin, San Mateo, Santa Clara, San Benito)

Then: Classify as conforming (high-balance if above $806,500). Full suite of conforming renovation and construction products available including HomeStyle, CHOICERenovation, and FHA 203(k). Rates will be slightly higher than standard conforming but significantly better than jumbo.

If: Loan amount $500K-$1M AND property in a baseline California county (conforming limit $806,500) AND loan exceeds $806,500

Then: Classify as jumbo for the amount above $806,500. Route to jumbo construction-to-permanent, portfolio lender, or consider restructuring (e.g., smaller first mortgage plus HELOC for renovation portion) to keep primary loan conforming.

If: Loan amount $1M-$1,209,750 AND property in California high-cost county AND borrower qualifies for conforming

Then: Route to high-balance conforming products (HomeStyle, CHOICERenovation, FHA 203k). This is the last tier where government-backed and GSE products are available. Emphasize to borrower the significant rate and term advantages of staying within conforming limits.

If: Loan amount exceeds $1,209,750 (or $806,500 in baseline counties)

Then: Route to jumbo construction loan. Require 680+ credit, 20%+ down payment, 6-12 months reserves. Identify lenders with jumbo construction programs (fewer available - California Bank & Trust, major national banks, portfolio lenders). Expect longer underwriting timelines (45-60 days).

If: Loan amount $2M-$3M

Then: Route to jumbo construction specialists or private banking. Require 700+ credit, 20-30% down, 12+ months reserves. Recommend California Bank & Trust (no max loan amount, 24-month construction term) or private bank relationship. Hard money available but expensive (10%+ rate).

If: Loan amount $3M+

Then: Route to private banking or super jumbo specialists. Require 720+ credit, 30%+ down, 18-24 months reserves. Relationship-based lending - recommend establishing private bank relationship before applying. Very few lenders serve this tier; expect fully negotiated terms. Hard money available from CA large-loan specialists for bridge/temporary needs.

If: Borrower credit score below 620 AND loan is for renovation/construction

Then: Conforming and most jumbo products are unavailable. Route to: (1) FHA 203(k) if credit 580-619 (3.5% down, limited lender selection); (2) Hard money/private lender if credit below 580 or property does not qualify for FHA (asset-based underwriting, expect 10%+ rate, 60-75% LTV max); (3) Portfolio lender with flexible underwriting. Advise credit improvement if timeline allows.

If: Borrower is self-employed with non-traditional income documentation

Then: Route to portfolio lenders offering bank statement qualification (12-24 months bank statements instead of tax returns). Available across all tiers. Expect 0.5-1.0% rate premium over full-doc loans. CFL-licensed lenders in California frequently offer these programs.

If: Property is investment or non-owner-occupied AND renovation/construction needed

Then: FHA products are ineligible (owner-occupied only). Route to: conventional investment property loans (HomeStyle allows 1-unit investment at 85% LTV max), hard money (primary vehicle for fix-and-flip), DSCR portfolio loans (qualify on projected rental income), or private construction loans. Expect 15-25% down minimum.

If: Borrower needs speed (close within 2 weeks) for construction or renovation financing

Then: Route to hard money/private lenders. California's dense private lending market enables 5-10 day closings. Asset-based underwriting bypasses lengthy income verification. Cost premium is significant (10%+ rate, 1-3 points). Best used as bridge financing with plan to refinance into permanent conventional loan after construction.

If: Project includes seismic retrofit in LA or SF mandatory retrofit zone

Then: Flag for Freddie Mac CHOICERenovation (explicitly allows disaster resilience improvements). Also check CalCAP Seismic Safety Financing Program eligibility. Ensure construction loan budget includes seismic engineering costs (can add 5-10% to hard costs). Verify whether renovation scope triggers full seismic code compliance under California Building Code.

If: Project is ADU construction AND loan amount $100K-$300K

Then: Route to ADU-specific construction loan products (Redwood Credit Union, SDHC ADU Finance Program in San Diego at 1% construction interest). FHA 203(k) and HomeStyle can also finance ADU construction based on after-improvement value. Note: most lenders do NOT count projected ADU rental income for qualification. CalHFA ADU Grant ($40K) is currently fully allocated.

If: Loan amount is near a tier boundary (within 10% of conforming limit)

Then: Actively explore restructuring to stay within conforming limits. Strategies: increase down payment to reduce loan amount below limit, split into first mortgage (conforming) plus HELOC (for renovation costs), or use personal loan for small overage. The rate differential between conforming and jumbo (0.25-0.75%) can save thousands over loan life.

California-Specific

  • 9 California counties are at the 2025 FHFA high-cost ceiling of $1,209,750: Alameda, Contra Costa, Los Angeles, Marin, Orange, San Benito, San Francisco, San Mateo, and Santa Clara. An additional 8 counties have limits between $897,000 and $1,178,750 (Santa Cruz, San Diego, Napa, Ventura, Monterey, San Luis Obispo, Santa Barbara, Sonoma). The remaining 41 counties are at the $806,500 baseline.
  • CalHFA does not offer standalone construction loans. Its primary programs are purchase-oriented first mortgages and down payment assistance (MyHome, ZIP, Dream For All). CalHFA FHA loans can be combined with FHA 203(k) Limited for minor renovations. The CalHFA ADU Grant Program ($40,000) is fully allocated with no current applications accepted.
  • California has a dual licensing framework for private/hard money lenders: DRE (Department of Real Estate) license and CFL (California Finance Lenders Law) license under DFPI. DRE licensees face construction loan restrictions, LTV limitations, and extensive disclosure requirements but can broker to individual investors. CFL licensees have no construction-specific restrictions, require $25K+ net worth and surety bond, but cannot broker to the public. Many firms hold both licenses.
  • Los Angeles and San Francisco have mandatory seismic retrofit ordinances targeting soft-story wood-frame structures, non-ductile concrete buildings, and unreinforced masonry buildings. Renovation projects in these cities can trigger seismic upgrade requirements depending on scope, potentially adding significant unplanned costs. Properties with outstanding mandatory retrofit orders may face lending restrictions.
  • California Title 24 Energy Code (2025 edition, effective January 1, 2026, locked through 2031 per AB 130) requires solar panels on new construction, heat pump readiness, and specific efficiency standards for renovations involving window replacement, HVAC changes, duct modifications, or insulation alterations. HERS rater verification is required for mechanical changes and major remodels. These requirements add $10K-$50K+ to project budgets.
  • California permitting timelines add 3-6+ months beyond national averages, with San Francisco and Coastal Commission jurisdictions taking the longest. This directly impacts construction loan term requirements - most California construction lenders offer 18-24 month terms versus the 12-month national standard. Extended timelines increase interest carry costs.
  • California's ADU-friendly legislation (state-streamlined permitting, SB 9 lot splits) has created a booming ADU construction loan market. Typical ADU costs range from $100K-$300K (median ~$150K per Terner Center). Local programs include SDHC ADU Finance Program (San Diego, 1% construction interest up to $250K), San Mateo County One Stop Shop, and Housing Trust Silicon Valley.
  • California has the highest concentration of private/hard money lenders in the U.S. (50+ identified construction-focused private lenders). Average CA private construction loan (Q3 2025): 10.29% rate, 1.3 points, $676,100 loan size, 71% LTV.
  • Executive Order N-29-25 temporarily suspended 2025 Title 24 solar and battery storage requirements for structures damaged in the 2025 Los Angeles wildfires, creating a temporary exception for fire-damaged property reconstruction in affected LA areas.
  • Mello-Roos Community Facilities District taxes in many California communities add 0.5-1.5% annually to property tax bills. These must be included in DTI calculations for construction loan qualification and can reduce maximum qualifying loan amounts.
  • PACE (Property Assessed Clean Energy) financing attaches to the property tax bill rather than the borrower and creates a lien senior to mortgage liens. Many conventional lenders require PACE liens to be paid off before approving a construction or renovation loan.

Common Misconceptions

Conforming loan limits apply the same way to construction loans as they do to traditional purchase mortgages.

During the construction phase, loans are typically underwritten as short-term specialty or portfolio products, NOT as conforming residential mortgages. The conforming limit becomes relevant only when the construction loan converts to a permanent mortgage (in a one-close construction-to-permanent structure). Stand-alone construction loans and private/hard money construction loans operate entirely outside GSE conforming guidelines.

LTV for construction loans works the same as traditional mortgage LTV (loan amount divided by current appraised value).

Construction loans use two separate metrics: Loan-to-Cost (LTC = loan amount divided by total project cost including land, soft costs, and hard costs) and Loan-to-Value (LTV = loan amount divided by after-completion appraised value). The more conservative ratio controls loan sizing. Renovation loans (FHA 203k, HomeStyle) uniquely base borrowing on after-improved value, allowing borrowers to access more funding than current property value alone would permit.

A personal loan is a reasonable alternative to a construction loan for major home renovations.

Personal loans are unsecured with typical limits of $35K-$100K and interest rates of 7-36%, far higher than construction loan rates (6-10% conventional, 10-14% private). They lack the structured draw process that protects both borrower and builder through milestone-based disbursements. A HELOC, FHA 203(k), or HomeStyle renovation loan is almost always preferable for projects exceeding $25K-$50K due to lower rates, higher limits, and structural protections.

You must own the land free and clear before you can get a construction loan.

Construction loans can include land purchase as part of the first draw. Single-close construction-to-permanent loans can cover lot purchase, construction, and permanent financing in one transaction. If you already own land, existing equity can count toward the required down payment. FHA one-time close construction loans can include lot purchase.

Any mortgage lender can originate a construction loan.

Most conventional mortgage lenders do NOT offer construction loans. Construction lending requires specialized underwriting expertise, draw management systems, builder vetting processes, and inspection coordination. HomeStyle Renovation lenders must have Fannie Mae special approval with 2+ years renovation lending experience. Working with inexperienced lenders leads to delays, funding problems, and potential project failure.

The FHA 203(k) loan limit is the standard FHA floor ($524,225) everywhere in California.

FHA 203(k) loan limits vary by county and match the general FHA limits, which in California's 9 high-cost counties reach $1,209,750 for 2025. This means FHA 203(k) can finance renovations well into the $1M+ range in San Francisco, Los Angeles, Orange County, and the Bay Area, making it one of the most powerful high-LTV renovation tools in California's expensive markets.

Jumbo construction loans require 30%+ down payment in all cases.

While jumbo construction loans require larger down payments than conforming products, the actual requirement varies by loan size and lender. In the $1M-$1.5M range, some lenders accept 15-20% down with strong compensating factors (high credit score, substantial reserves, low DTI). The 25-30% down requirement typically applies to loans above $2M.

Construction cost overruns are covered by the construction loan contingency.

Lenders typically require a 5-15% contingency reserve built into the approved construction budget, but this is finite. Exceeding the approved budget requires lender approval of change orders and may require additional borrower equity injection. In California, Title 24 compliance costs, seismic requirements, and permitting delays frequently cause overruns that exceed standard contingencies. Experts recommend budgeting a personal 10-20% buffer above the lender-required contingency.
