What to know about construction working capital and bridge financing in San Francisco

San Francisco's construction market is active and expensive. Labor costs sit among the highest in the country, permit timelines are long, and general contractors often wait 45–90 days for payment on public and private jobs alike. That gap between when you pay your crew and when an owner pays you is where most cash-flow problems start — and it's exactly what working capital loans and contractor bridge loans are built to close.

Before you apply anywhere, it helps to know which product actually fits your situation.

The core options — and who they fit

Invoice factoring is the fastest path when you have outstanding invoices from creditworthy owners or GCs. Factoring companies advance 80–90% of invoice face value and fund in 1–3 business days. Fees run 1–5% of the invoice amount. Your credit score matters less than your client's. This is the go-to for subcontractors stuck in slow-pay cycles on commercial or government jobs.

Working capital loans (online lenders) work for contractors who need a lump sum for payroll, materials, or overhead and don't have invoices to factor. Expect 15–45% APR from online lenders — the spread is wide because credit score, time in business, and revenue all move the rate significantly. Most lenders want $250,000+ in annual revenue and will pull 12 months of bank statements. Approval can be 1–3 business days.

Business lines of credit are better for firms that need recurring liquidity across multiple projects. Rates run 8–20% APR for qualified borrowers. Banks and credit unions offer the best terms but require stronger profiles; online lenders are faster but more expensive. A line of credit lets you draw, repay, and draw again — ideal if your cash needs are cyclical rather than one-time.

Contractor bridge loans are short-term, single-draw products used to fund a specific gap — equipment mobilization, bonding collateral, or a large material purchase before a draw is approved. They're priced similarly to working capital loans and are often structured with a defined repayment event (receipt of a progress payment, close of a refinance, etc.).

SBA 7(a) loans offer the lowest rates (8.5–11% APR in 2026) and the longest terms, up to 10 years for equipment or working capital. The tradeoff is time: approval runs 30–45 days, you need 24+ months in business, and the minimum credit score is 640. The SBA guarantees up to 85% of the loan, which makes banks more willing to lend — but it doesn't make them faster. Use this for planned capital needs, not emergencies. The maximum loan amount is $5,000,000.

What trips contractors up

• Debt service load. Lenders want your total monthly debt obligations below 43–50% of gross monthly revenue. If you're already carrying equipment loans or a line of credit, that ceiling fills up fast. Know your number before you apply.
• DSCR. Most lenders require a debt service coverage ratio of at least 1.25x — meaning your net operating income must cover loan payments by 25% or more. Thin-margin jobs hurt this ratio even when revenue looks healthy.
• Time in business. SBA requires 24 months. Many online lenders will go to 12 months or less, but rates climb sharply for newer firms.
• Bank statement cash flow vs. tax return income. Online lenders often underwrite primarily on bank statements (12 months). If your returns show aggressive depreciation write-downs, your taxable income may look lower than your actual cash flow — clarify this with your lender upfront.

Contractors in other high-cost markets face similar dynamics. The same product lineup applies to firms working in Anchorage or doing civil work in Atlanta, though local prevailing wages and bonding requirements shift the numbers.

If equipment is part of your financing picture — a new excavator, crane, or fleet vehicle — working capital and heavy equipment financing for San Francisco contractors are often structured separately, since equipment loans use the asset as collateral and typically carry lower rates (5.5–9% APR for 700+ credit). For excavation-specific needs, excavator loan and lease options for SF-area contractors cover rate tiers, Section 179 treatment, and fast-approval paths in detail.
