Welcome to Platting

Harris County is the 3rd most populous county in the United States; it is paramount to remain strategically organized and equipped to offer the very best service possible to our constituents, the development community and municipal partners. As a regulatory agency, it is our goal to assist the development community in envisioning, creating and building vibrant and sustainable developments for all residents of the unincorporated areas of Harris County. We trust that this online tool will be of assistance to anyone looking to develop within the unincorporated areas of Harris County. 

The Platting Staff is charged with enforcing the Regulations of Harris County, Texas for the Approval and Acceptance of Infrastructure as amended from time to time by the Harris County Commissioners' Court. Our knowledgeable and professional staff is dedicated to doing everything possible to ensure that all subdivision related projects are handled in a professional, courteous and timely manner. 

 

Extraterritorial Jurisdiction 

Several municipalities have extended their development ordinances to require municipal review and approval of subdivision of land within their extraterritorial jurisdictions in unincorporated Harris County. Below are links that will take you to each of their planning home pages for further development guidelines: 

Subdivision of land in certain areas (No ETJ) is solely reviewed and approved by Harris County Platting Group. Area Map 

 

Policy Affecting CPC-101 Expirations 

If an applicant has a plat mylar in our possession and there is a risk that it will not be promoted to Commissioners’ Court prior to the expiration of the CPC-101, an Extension of Approval (EOA) must be filed in a timely manner with the City of Houston. 

Chapter 42 allows for a single one year extension. Accordingly, if your final plat has not been promoted to Commissioners’ Court for approval prior to the expiration of your EOA, you will be notified in writing and your plat will be returned to the City of Houston for further disposition. Should this happen, you will be required to submit a new plat application with the City of Houston. 

 

Requirements of 30§TAC 285

In accordance with the requirements of 30§TAC 285 and the Rules of Harris County, Texas for On-Site Sewage Facilities, an On-Site Sewage Facility (OSSF) Subdivision Planning Report is required prior to approval of plats not located within a known service area for public sewer services. 

Please refer to OSSF Subdivision Planning Report for more information.
