The Houston Access Management Form is a data summary you file through the city’s iPERMIT portal any time a project adds or changes a driveway, curb cut, or other access point along a public street. It captures the property description, proposed land use, site plan, and driveway measurements the Traffic Management Branch needs to check your access points against Chapter 15 of the Infrastructure Design Manual.1City of Houston. Infrastructure Design Manual – Section 15.08 Access Management Standards Approval is a prerequisite for a building permit or driveway permit, so this step comes first.
What to Gather Before You File
Four items do most of the work. Missing any one of them stalls the review.
- The legal property description from your deed, plus the site’s street address.
- The proposed land use — retail, office, restaurant, warehouse, residential — because the city uses it to estimate trip generation.
- A scaled site plan showing the parcel relative to existing roads, with proposed driveways, sidewalks, existing utilities, easements, and any street trees affected by the new access.
- A traffic impact analysis, if triggered. TxDOT’s Houston District methodology, commonly referenced here, sets 50 peak-hour trips as the threshold for a minor study and 150 for a major study. Below 50, a formal study is generally not required, but the Access Management Form still is.2Texas Department of Transportation. TxDOT Houston District Traffic Study Guidelines
Every measurement on the form should come from a professional survey or sealed engineering plan. Harris County requires plans to be signed and sealed by a licensed engineer, and the city applies a similar standard to site plans involving right-of-way work.3Harris County Office of the County Engineer.

The Driveway Numbers Reviewers Will Check
The form asks for technical data on each proposed access point because staff engineers compare your numbers to the IDM’s driveway classifications. Type A is smallest and typically residential, Type B is medium-scale, and Type C is commercial and high-volume. Each carries its own spacing rules.4City of Houston. Infrastructure Design Manual – Section 15.2.07 and Table 15.7
- Type A: at least 20 feet between adjacent driveways on the same property, 20 feet from the adjacent street right-of-way, and 4 feet from the side property line. Two driveways per property maximum.
- Type B, 20 lots or fewer: at least 30 feet between adjacent driveways and 30 feet from the adjacent street right-of-way.
- Type B, more than 20 lots: at least 40 feet between adjacent driveways and 40 feet from the adjacent street right-of-way.
- Type C: spacing depends on frontage and street classification. A parcel with up to 170 feet of frontage on a major thoroughfare gets one driveway set back at least 100 feet from the intersection; on a local street the offset is 60 feet. With 170 to 250 feet of frontage, two driveways are allowed with at least 40 feet between them.
Angles and widths matter too. Two-way driveways must meet the street at roughly 90 degrees. One-way driveways can angle between 45 and 90 degrees, but only where they connect to one-way or divided streets with no median opening.5City of Houston. Infrastructure Design Manual – Section 15.2.07.C.1.h No driveway radius may encroach on an abutting property or a corner radius, and driveways are prohibited within the limits of any intersection as defined by Table 15.8.
Individual driveways on narrow lots cap at 12 feet wide. Courtyard-style developments allow 12 to 18 feet, measured at the property line.6Municode. Houston Code of Ordinances Chapter 42 – Division 4 Lots and Reserves Type C driveways must stay tangential and hold a uniform throat width for at least 20 feet past the property line so queuing vehicles don’t spill back onto the street. Where a median exists, place driveways at least 75 feet from the median nose or align them with the median opening.
Filing Through iPERMIT
Applications go through Houston’s iPERMIT online portal. Create an account at the Houston Permitting Center’s portal, then select the appropriate permit category for your project.7City of Houston. iPermits Customer Portal Upload the completed Access Management Form, the site plan, and any traffic study as PDFs. The portal uses a shopping-cart-style checkout for fees.8Houston Public Works. iPermits Non Licensed User Instructions
The city’s published fee schedule lists a driveway permit (approach in right-of-way) at $47.9City of Houston. City-Wide Fee Schedule Larger projects that require additional plan review or a traffic impact analysis run higher. Pay by credit card or electronic check through the portal’s secure gateway. The confirmation receipt carries the reference number you’ll use to track the file.
The Builders Bond You’ll Need Before Construction
Before any work in the public right-of-way, the city requires a Sidewalk, Driveway, Curb and Gutter Builders Bond of $2,000 under IDM Section 10.06D.10SuretyBonds.com. Houston Sidewalk, Driveway, Curb and Gutter Builders Bond It acts as a performance guarantee: if construction is deficient, the city can draw against it to correct the work. Contractors usually carry the bond, but confirm it is in place before crews mobilize.
What Happens During Review
Once your application is in queue, staff engineers at the Traffic Management Branch check the submission against the IDM standards, evaluating driveway spacing, intersection clearance, throat width, and how the site plan handles existing utilities and easements.11City of Houston. City of Houston Standard General Requirements – Section 1.04 Clean submissions move through and show approved status in the portal. When reviewers find conflicts, they issue a request for revisions or additional information.
The plan review process generally expects corrected drawings back within seven business days of comments.12Houston Permitting Center. Plan Review Delay pushes your file back in the queue. The revisions asked for most often: driveway placement that violates the offsets in Table 15.8, throat widths below the minimum for the driveway type, and missing utility or easement information on the site plan.
An approved Access Management Form is the gate to a building permit or driveway construction permit. It also locks in the location, design, and number of access points agreed on with the city, so treat the approved plan as the version to build.
If Your Property Fronts a State Road
The city form covers city streets. If your property fronts a state highway or another TxDOT-maintained road, you also need a Driveway Access Permit (DAP) from TxDOT’s Houston District, submitted through its own DAP portal rather than iPERMIT.13Texas Department of Transportation. Driveway Access Permits and Drainage Guidelines TxDOT asks for surface utilities and drainage structures on its right-of-way, every intersection, driveway, on-ramp, and traffic signal within 1,000 feet of the proposed access, and the posted speed on adjacent TxDOT highways.14Texas Department of Transportation. General Instructions to Driveway/Access Permit Applicants Spacing must meet TxDOT’s Access Management Manual, and work involving turn lanes, roadway widening, or median changes can trigger environmental reports, a traffic control plan under TxDOT standards, and a stormwater pollution prevention plan. The two reviews run independently: approval from one does not carry to the other, so build a site plan that satisfies both before you submit.
