Collin County Subdivision Bonds, Plat Security and Right-of-Way Terms

Section 1.04.C sets out the choice. Under the standard election, the Director of Engineering holds the approved plat and releases it for recording only after the road and drainage work is accepted and the warranty and maintenance bond are in place. The regulations state that no lots may be sold until the plat is recorded, so this route trades bond cost for time: the developer carries the land and the construction loan until acceptance.

The second route records the plat earlier against a performance bond or a financial guarantee in lieu of bond, which can be cash or a letter of credit. The amount equals the estimated cost of construction of the road and drainage infrastructure improvements, based on a Texas professional engineer's estimate and approved by the Director of Engineering. The bond must comply with Local Government Code section 232.004 and a letter of credit with section 232.0045, and the obligee is the County Judge.

The security runs two years from the date the plat is recorded. That is a fixed window, so a schedule that slips past two years is a conversation with the County and the surety, not a formality. A performance bond is released when a maintenance bond is substituted, or it is held through the warranty period if it is written to cover maintenance as well.

• Standard election: plat held by the Director of Engineering until acceptance; no lot sales before recording.
• Bond election: performance bond, cash or letter of credit equal to the engineer's estimated construction cost.
• Term: two years from plat recording, with the County Judge as obligee.

The developer normally posts the performance bond. The regulations let the County allow the prime contractor to post it instead, but they also say the County will not accept a series of separate bonds from contractors or subcontractors on the project. A developer that planned to assemble security from the paving, utility and drainage subcontractors' own bonds needs one instrument covering the full estimate.

That shapes the surety conversation. A single developer bond is typically underwritten on the developer's balance sheet, the land and the indemnitors behind the entity, while a prime contractor's bond rests on that contractor's capacity. Either way, the surety will want the engineer's estimate the Director approved, the construction contract and a schedule that fits inside the two-year term. Results can vary by surety guidelines and programs, and all of it is subject to underwriting and the terms of the bond issued.

Posting a bond records the plat, but it does not open the lots to building. Section 1.04.C.2.e says anyone who undertakes residential or commercial construction on a lot before the road and drainage improvements are accepted as complete by the County commits an offense under the regulations. The maintenance bond requirement must also be met first.

For a builder buying lots in a bonded County subdivision, that is a takedown question as much as a legal one. Builders risk on homes, the builder's own general liability and the lender's draw schedule all assume construction can start; the County rule says it cannot until the developer's infrastructure is accepted. Purchase contracts and insurance start dates typically follow the acceptance date rather than the recording date.

Section 1.09 sets the maintenance bond at 100% of the cost of roadways, signs, stormwater control improvements and drainage structures. The warranty period runs two years from the County's acceptance of the work as complete, and a letter of credit may be allowed in some cases. A 100% maintenance bond is a full-value obligation, so sureties typically look at it much like a second performance bond rather than a small warranty instrument.

Private roads do not escape the requirement. Section 1.11 applies the same bonding, warranty and County roadway standards to private roads and states that private roads are not eligible for County maintenance. The 2026 summary of changes adds that repairs completed under a performance bond or other financial guarantee do not constitute County acceptance of private road maintenance, so a bonded repair does not shift upkeep to the County.

The same 2026 update brings RV parks and single-family rental developments into platting and adds special district plat notes. A build-to-rent community in the unincorporated county should expect the plat, bond and acceptance steps above, along with completed-operations coverage that lasts through the two-year maintenance period.

Collin County Public Works requires a permit for utilities placed along or across County roads. The Right of Way Use Policy, approved by Commissioners Court on February 1, 2021, requires lines under existing roadways and paved driveways to be bored, and an open cut carries a fee in addition to the repair cost. The owner agrees to indemnify and hold harmless the County, its agents and employees from suits, actions and claims.

The policy states no dollar insurance minimum and no right-of-way bond amount. Confirm with Public Works what certificate, limits or additional insured wording it will ask for before a crew mobilizes, and have the indemnity read against the contractor's contractual liability coverage, which can vary by carrier guidelines and programs.

Special districts add a step at acceptance. In a special district such as a municipal utility district, the 2026 regulations require an interlocal agreement approved and executed by Commissioners Court for County enforcement of traffic regulations within the district. District financing, the developer's agreement with the district and the County acceptance schedule should be planned together, since the maintenance bond clock starts at acceptance.
