Subdivision bond vs. letter of credit: which should a developer use?

A subdivision bond frees up the bank credit line that a letter of credit ties up — for most developers, that cash-flow difference is the deciding factor. Both instruments satisfy a municipality's requirement to guarantee public improvements, but they draw on very different sources of your capacity, and they cost and release differently.

The core difference: what they tie up

A letter of credit (LOC) is issued by your bank and reduces your borrowing capacity dollar-for-dollar — the amount is frozen against your credit line until the improvements are accepted. A subdivision (surety) bond sits outside your bank relationship entirely, so it leaves your credit line free for land, materials, and the next project. For an active developer, that preserved liquidity is usually worth more than any rate difference.

Cost

An LOC typically carries an annual fee of roughly 1%–2% of the amount plus bank charges, and it usually requires cash or assets pledged as collateral. A subdivision bond typically costs 1%–3% of the bonded improvement cost per year and, for a qualified developer, generally requires no cash collateral — the surety underwrites your balance sheet instead of freezing your cash.

Collateral and approval

The bank behind an LOC will usually want collateral and covenants. A surety underwrites the developer's financial strength and the cost to complete, so a well-capitalized developer can post a bond without locking up cash. Newer or thinner balance sheets may see collateral requested on either instrument.

Release

Both are released when the municipality accepts the completed improvements, and both typically allow phased reductions as work is inspected and signed off. The practical difference is what you get back: releasing an LOC restores bank capacity, while releasing a bond simply ends the premium — your cash was never tied up to begin with.

For most developers who want to keep their bank line available for the deal itself, the subdivision bond is the stronger tool. Send us your municipality's requirement and the engineer's estimate and we'll structure the bond — and show you the side-by-side against an LOC for your specific project.
