How To Apply For A Building Permit In Houston, Texas?

Whether you are planning to build a new home, add new rooms, do structural changes, or even simply renovate the building, you will need a building permit before anything. 

But securing a permit is not that easy in Houston. You need to submit an application, have all the required documents in place, and meet all the required city department criteria to get an approval. 

Not to mention, the permit requirements can be also different within the Houston metro area based on where your property is located. That’s because the City of Houston and unincorporated Harris County have different permitting processes. 

Also, some projects where extensive structural work or renovations are involved have extra residential design permitting and review requirements. 

Now, I am sure all of these sound quite overwhelming and confusing at the same time. That’s why in this blog, I have explained how to apply for building permit in Houston in detail and without unnecessary complications. 

So, let’s have a look up close.

Key takeaways

• Before you apply for a permit, check which authority handles permits for your property.
• Look at exact permit requirements and have all the necessary drawings, forms, and supporting documents handy.
• Submit your application through the correct official process and get the required permit before starting any work.
• Also get required inspections and final approvals to close out the project properly.

Do you need a building permit in Houston, TX?

Whether or not you need a permit depends on the type of work you want in your home, your property’s location, and the applicable building regulations. 

But as a rule of thumb, all new constructions, home additions, structural changes, and some building-system installations or alterations do require a permit in the Houston area. 

Here are some projects that need a permit before any work can start: 

Note: Even those projects that are not mentioned in this list might require a permit. I suggest you check your applicable permitting requirements before any work begins.

Where to apply for building permit in Houston?

If your property is in the Houston Metropolitan Area, it might fall under either of the two jurisdictions:
A. City of Houston

B. Harris County

Now, if your property falls under the City of Houston’s jurisdiction, do check out the city’s official permit portal. This portal provides access to permit applications, payments, permit searches, and application tracking. 

However, if your property is in the unincorporated Harris County, you fall under a different jurisdiction. Here, you can use the Harris County Permits website and its Permits A to Z directory to know which applications you need to fill and to apply for building permits. 

Pro tip: Confirm your property’s permitting jurisdiction before preparing drawings or paying application fees. A Houston mailing address alone does not specify which authority handles your project, as your property can be in either City of Houston or Harris County’s jurisdiction. 

How to apply for building permit in Houston?

Having confirmed which jurisdiction your property falls in, you can now apply for building permit. And to do so, here are five steps you can follow:

#1. Confirm the exact permit requirements

When you fill in the application form, describe exactly what you plan to build, remove, or change. And as you do this, check whether you need a building permit, separate trade permits, site development approval, or other reviews.

For instance, a home addition might require more than a basic application. Here, depending on the scale of the project, you might need a site plan, foundation details, floor plans, grading information, or drainage documents.

Pro tip: Do check the conditions specific to your property early on. That’s because existing structures, property lines, drainage easements and patterns, and building setback requirements can all affect where and how you can build. 

#2. Prepare the application and required documents

Next up, gather the forms and supporting documents needed for your project. Depending on the scope of work, these can include:

• Completed permit application and property-owner information.
• A clear description of the proposed work and its location.
• A site plan or property survey for site development engineering, when needed.
• Architectural or engineering drawings.
• Structural calculations or other technical documents, when applicable.
• Project-specific forms and supporting approvals.

For instance, the City of Houston’s residential permitting guidance identifies application forms, ownership declarations, and scaled construction plans among its requirements for residential projects applications. So it makes sense to have these handy. 

Also, never make an incomplete or inconsistent submission such as a conflict between scope of work in the application and the architectural drawings. Make sure the project description, drawings, dimensions, and supporting documents are in sync with one another.

#3. Submit your application through the correct permit process

Submit your application and supporting documents using the process specified by your permitting authority.

For City of Houston projects, some applications use iPermits, with electronic plan submissions or extra steps required for some projects. Harris County, at the same time, uses its own ePermits process for permit applications.

Follow the instructions for your specific permit type. Some applications require you to upload forms separately from construction plans, so don’t assume that every document belongs in the same upload field.

Also, keep your project number, submission confirmation, and copies of your documents handy. You will need them to follow up on the application and respond to any requests.

#4. Pay fees and complete the plan review

After application submission, the permitting office will review your application and any required plans. Here, depending on your project, reviewers can examine building-code compliance, structural details, site conditions, drainage, or other requirements.

You might also receive comments asking for missing information, corrected drawings, or additional documentation.

I suggest you read each comment carefully and address the specific issues. If you send back only part of the requested information, it can lead to another review cycle.

#5. Obtain the permit before starting work

Once the required reviews and approvals are complete and you have paid the permit fees, you can now obtain the permit.

I always advise my clients to read the permit conditions carefully and have all the approved documents available throughout the construction work and afterworks. 

Also, you should start any new construction, home addition, or structural changes only after you have received the permit. I have seen homeowners mistake preliminary comments as a green signal to start construction, only to end up with a fine. 

How much does a building permit cost in Houston?

Building permit costs in Houston depend on the type of construction, project size, construction valuation, plan review requirements, and any additional inspections or approvals. 

In the City of Houston, the minimum permit fee for most building permits except for plumbing permits is $91.06. Also, a separate administrative fee of $33.56 can apply. 

Here, new residential construction, additions, and larger projects can cost more because fees are calculated using project-specific rates and square footage. I suggest you check City of Houston’s official fee schedule to estimate costs.

In Harris County, a residential development permit for a new single-family or multifamily dwelling or manufactured home costs $165. An extra $73 inspection fee applies when the structure is in a designated floodplain, floodway, or Coastal High Hazard Area, bringing the total to $238.

How long does it take to get a building permit?

The time it takes to get a building permit in Houston depends on your project type, application completeness, and the reviews required. As a rule of thumb, you can expect about 1-3 weeks for an initial review of a straightforward residential project. Complex residential and commercial projects can take several weeks or longer to receive final approval though.

Here’s how long it exactly takes in both City of Houston and Harris County:

City of Houston

The city’s published review data for May through July 2024 recorded median review times of approximately 7-8 days for residential projects and 7-10 days for commercial projects. 

Also, in July 2025, the city launched a pilot program aimed at issuing permits for selected single-family residential projects within 30 business days or less. 

Harris County

The county lists a processing time of 15 business days for such commercial building permits that require certain reviews. 

Residential development permits follow different procedures, and I suggest you confirm the expected timeline for your specific permit with the Harris County Office of the County Engineer.

How do you check or close out a building permit?

To check a permit for City of Houston permits, you can check out the city’s permit portal. For Harris County projects, you can use the county’s permits website. Do have your project number or property information ready as you check for permits using these platforms.

To close out a permit, confirm that all required inspections have passed, outstanding corrections have been addressed, and any final approvals have been issued. Some projects might also need a certificate of occupancy or another form of final authorization.

Most importantly, never assume that the permit is closed just because construction is finished. An outstanding inspection or approval can leave the project incomplete in the permitting system. You should always check the project’s status with the permit issuing authority and ask what remains if the permit is still open.
