- Faster and cheaper than a letter of credit
The bond that unlocks your commercial building permit.
A Texas site improvement bond is a three-party surety guarantee: the owner or developer (principal) promises to build the public improvements required by the site plan; the city or county (obligee) accepts the site plan and issues the building permit in reliance on that promise; and the surety company stands behind the developer financially.
Almost every commercial project in Houston — a new strip center, a medical office, an industrial warehouse, a self-storage site, a restaurant pad — has to make some changes to public infrastructure at the edge of the property. New driveways. Rebuilt sidewalks. Drainage tie-ins. Water and sewer taps. The city will not issue a certificate of occupancy until those public improvements are built and accepted.
If the developer goes dark mid-construction and the public improvements are incomplete, the city draws on the bond and finishes the work itself. The bond keeps the city from being stuck with an unfinished driveway approach or a half-built sidewalk at the neighbor\'s expense.
Priced on developer credit, scaled to improvement value.
Underwriting mirrors subdivision bonds — personal and business financials, credit, project pro forma. Most site improvement bonds are smaller than subdivision bonds, so premiums are lower in absolute dollars.
| Developer tier | Rate (% of bond) | $100K bond, 1 yr |
|---|---|---|
| Established developer 750+ credit, strong balance sheet | 1.0–1.5% | $1,000–$1,500 |
| Standard developer 680–749, solid financials | 1.5–2.5% | $1,500–$2,500 |
| Emerging developer 620–679, first commercial project | 2.5–4.0% | $2,500–$4,000 |
| Credit-challenged Sub-620 or thin liquidity | 4.0–5.0% | $4,000–$5,000 |
Rates are annual. Bonds renew if construction outruns the 1-year term.
Four steps — driven by your site plan approval.
- 01
Engineer\'s cost estimate
Your civil engineer prepares a sealed cost estimate for the public-improvement portion of the site work — driveways, sidewalks, drainage tie-ins, utility extensions. The city reviews and accepts the estimate.
- 02
Owner/developer financial package
Personal and business financial statements, credit authorization, and signed general indemnity agreement. For bonds over $250,000, reviewed business statements.
- 03
Bond issued on city form
City of Houston, Harris County, Fort Bend, Montgomery, and each suburban city have their own site improvement bond forms. We pull the current approved form and issue to spec, typically within 24–48 hours.
- 04
Construction, inspection, release
Bond stays in force until the city inspects and accepts the public improvements — usually at certificate of occupancy. Bond releases automatically on acceptance.
State authority, local forms, bond scope.
Texas Local Government Code Chapter 212 authorizes municipalities to require surety for public improvements tied to private development. The same statute that backs subdivision bonds covers site improvement bonds on commercial projects.
City of Houston Infrastructure Design Manual and Code of Ordinances set local requirements. Most Texas suburban cities publish their own site improvement bond forms inside their development manuals.
Typically 100%–125% of the engineer\'s estimate for the public-improvement scope only. The private on-site work — buildings, parking lots, internal landscaping — is not included in the bond.
1 year is standard, written with renewal language. Bond releases automatically on city acceptance at certificate of occupancy.
Cash escrow and irrevocable letter of credit are also accepted. Surety bond is typically the cheapest and most flexible option, especially for developers running multiple projects concurrently.

Site improvement bond questions from Texas developers.
What is a site improvement bond?
A site improvement bond is a surety bond an owner or developer posts with a city or county to guarantee public improvements on a private commercial site will be built per approved plans. Typical scope: driveway approaches, sidewalks, curb cuts, drainage tie-ins, water and sewer service extensions, and street-light relocations. It is the commercial-project sibling of the subdivision bond.
How is this different from a subdivision bond?
Subdivision bonds cover residential plats — the public infrastructure inside a new neighborhood. Site improvement bonds cover commercial, mixed-use, institutional, or industrial projects where the private development is adding or modifying public improvements at the edge of the property. Same statutory authority (Local Government Code Ch. 212), different form, different scope, often smaller dollar amount.
When is a site improvement bond required?
Houston and most Texas municipalities require one whenever a private commercial project touches public right-of-way — new driveways onto a public street, sidewalk replacement, new utility taps, offsite drainage work, or street-lighting changes. It is a condition of the building permit or certificate of occupancy.
How much is the bond amount?
Typically 100%–125% of the engineer's estimate for the public-improvement portion of the site work — not the whole project. For a strip center or medical office with basic curb-cut and sidewalk scope, bonds run $25,000–$150,000. Larger mixed-use projects with offsite drainage can run $500,000 or more.
How much does a site improvement bond cost?
Premium runs 1%–3% of the bond amount for developers and owners with strong financials. A $100,000 site improvement bond typically costs $1,500–$3,000 per year. Weaker credit pushes rates to 3%–5%.
How long does the bond stay in force?
Until the city inspects and accepts the public improvements — usually at certificate of occupancy or shortly after. Most are written as 1-year terms with automatic release on municipal acceptance. If construction slips, the bond renews for another year.
