Denton County Subdivision Bonds and Right-of-Way Requirements

Section X.V.1 sets the construction bond at 100% of the estimated cost of construction including drainage structures. It is filed with the preliminary plat, written by a surety authorized in Texas and payable to the County Judge. Construction must be complete within two years after preliminary plat approval, so the bond term and the construction schedule are tied to the same date.

Section X.V.4 allows an irrevocable letter of credit in lieu of bonds, with approval by the District Attorney and Commissioners Court. That approval path adds a step a bond does not, and a letter of credit draws on the developer's bank line rather than surety capacity. Which instrument fits typically depends on the developer's lender, its balance sheet and how many other projects are open.

Because the bond is filed at the preliminary plat stage rather than at final plat, it often lands before the construction contract is signed. The surety will usually want the engineer's estimate that sets the amount and some view of who will build the work.

Section VI.19 lets a developer post a bond instead of finishing construction before the final plat. Here the estimated construction cost must include a contingency factor of 20%, and the bond is not released until the County accepts the improvements for maintenance. The same document states the construction bond amount in Section X.V.1 as 100% of the estimate without that contingency. Both statements are in the County's posted rules; ask the County which figure it will apply to your plat before the surety sizes the bond.

Two related instruments use the same 20% idea. A development permit for unplatted land under Section VI.20 requires a performance bond, letter of credit or escrow agreement to cover the cost of the engineering and surveying process plus a 20% contingency. An erosion bond applies where 75% grass coverage is not reached, written in the rules as 120% of $200 per disturbed acre.

• Construction bond (Sec. X.V.1): 100% of estimated cost including drainage structures.
• Bond in lieu of completion (Sec. VI.19): estimated cost plus a 20% contingency, held until County acceptance.
• Development permit on unplatted land (Sec. VI.20): engineering and surveying cost plus 20%.
• Erosion bond: 120% of $200 per disturbed acre where grass coverage falls short.

Section X.V.2 substitutes a maintenance bond for the construction bond when the construction bond is released. It equals 10% of the estimated cost of construction including drainage structures and requires the improvements to be kept in a good state of repair for two years from the official release of construction security.

Final acceptance comes no earlier than two years after preliminary acceptance, or after the sale and completed construction of 60% of the platted lots. On a slow-selling subdivision, that second trigger can tie the acceptance date to lot sales and home construction rather than to the paving schedule alone.

A facilities agreement under Section X.VI is required for off-site extensions, multiple phases or a construction schedule longer than one year, and it must include a hold-harmless indemnity. That indemnity is a contract obligation the developer's general liability policy may or may not respond to, depending on its contractual liability terms, which can vary by carrier guidelines and programs.

Denton County's Right-of-Way User Best Practices, updated November 3, 2025, require a Right-of-Way Use permit any time work takes place over, under or along a County-maintained roadway. Once the inspector is satisfied, the permit is marked completed and a 12-month warranty period begins. Road Policy 8.11 in the subdivision rules has the applicant indemnify the County for 12 months after the installation is accepted, and Section 8.8 requires road crossings to be bored and encased in schedule 40 steel.

Neither the right-of-way guidance nor the County's Utility Installation Requirements states an insurance limit or a permit bond amount. Confirm with Development Services what certificate, limits or additional insured wording the County expects before crews mobilize. The 12-month warranty also means the contractor's completed-operations coverage and the indemnity sit behind the work for a year after the permit closes.

A Denton County subdivision typically needs a surety relationship that can carry a 100% construction bond early, a 10% maintenance bond after release and smaller permit and erosion instruments along the way, plus contractors whose liability coverage matches the County's indemnity and warranty periods. The insurance terms the County imposes on developers were not found in the documents we read, so the certificate requirements are a question to settle with the County at the start.

Developers working on both sides of the county line can compare this with Collin County, whose October 2026 rules use a 100% maintenance bond. Each county's figures should be confirmed with that county.
