If your contractor is talking about "filing with the city," and your bathroom is inside the Town of Highland Park, that is the first sentence you need to stop and ask about.
Highland Park is not part of Dallas. It is a separately incorporated municipality with its own town hall, its own building inspection department, and its own permit fee schedule. The City of Dallas permit office on Jefferson Boulevard does not handle anything inside the Town limits. A contractor that files Dallas permits regularly and Highland Park permits rarely is going to learn the difference on your project, and you are going to pay for the learning curve in calendar weeks.
This guide is the version we wish every Highland Park homeowner had read before they signed a remodel contract.
Why HP permits are different from Dallas city permits
Three real differences, not bureaucratic trivia.
One, the submittal packet. The Town of Highland Park requires a building permit application with plans, specs, contractor license verification, insurance certificate, and (when applicable) a notice to neighboring property owners. The City of Dallas requires a different form set, with a different plan-review process. A contractor filing their first Town packet usually misses something on the first submission and has to refile. That is a 5 to 10 working day delay, baked in.
Two, the plan review timeline. Town of Highland Park targets a 5 to 10 working day plan review for residential remodel permits. The City of Dallas residential bath remodel can move faster on Express Review or slower on standard intake. In practice, an experienced HP contractor lands a complete packet on Monday and gets approval by the following Friday or Monday. An inexperienced filer can wait 3 to 4 weeks for the same approval.
Three, the inspector. The inspector who shows up at your home is a Town of Highland Park inspector. They have specific local expectations. They are firm on the conservation district overlay where it applies. They tend to inspect quickly when paperwork is clean and they tend to red-tag when paperwork is sloppy. They are not the same people the contractor sees on Dallas city jobs.
The Town of Highland Park Building Inspection Department
Address. Town Hall is at 4700 Drexel Drive, Highland Park, TX 75205. The Building Inspection Department is inside Town Hall.
Hours and contact. Standard business hours, Monday through Friday. The Building Department posts current contact numbers, fee schedules, and the residential permit application packet on the Town of Highland Park official website. Call before you visit if you are filing as a homeowner rather than through a contractor.
What they handle. All residential and commercial building, plumbing, electrical, mechanical, demolition, and irrigation permits inside Town limits. Conservation District design review on streets within the overlay.
What they do not handle. Anything outside the Town limits. If your address is on the University Park side of the line, you file with University Park, not Highland Park, even if the house is two doors down from a Highland Park property.
The four permit types you might need for a bath remodel
A typical full bath remodel inside the Town limits triggers two to four separate permits, depending on scope.
1. Building permit (primary)
This is the umbrella permit for the project. It covers demolition of finishes, framing changes, drywall, tile, and the general renovation work. Required for any bath remodel that touches more than cosmetic finishes. A "paint and replace the vanity" job sometimes flies under the threshold. A full gut does not.
Typical fee range: $150 to $600 depending on declared project value.
2. Plumbing permit
Required if you are changing the location of any fixture, replacing the shower valve, replacing the water heater feeding the bath, or altering any drain or vent. Filed by the licensed master plumber doing the work, not by the homeowner or the general contractor.
Typical fee range: $100 to $300.
3. Electrical permit
Required for any change to circuits, GFCI placement, lighting fixture relocation, exhaust fan replacement (when ducted to exterior), or addition of new circuits for items like heated floor mats, towel warmers, or smart mirrors. Filed by the licensed master electrician.
Typical fee range: $100 to $250.
4. Mechanical permit
Required if the project changes HVAC ductwork (rare for baths) or if the exhaust fan ventilation routing changes meaningfully. Often "not applicable" for a straightforward remodel. If your contractor includes it without a clear reason, ask.
Typical fee range: $80 to $200 when applicable.
Total typical permit cost for a Tier 2 full bath remodel in Highland Park: $400 to $1,200 across the bundle, depending on project value and how many of the sub-trades trigger.
Conservation district overlay (the part that surprises people)
Ready to compare vetted project options?
Use Project Match privately when your scope is clear enough for contractor conversations.
Start Project MatchHighland Park has a conservation district ordinance that applies to specific streets and properties within the Town. The overlay is designed to preserve the architectural and historic character of the neighborhood. Most bath remodels do not trigger conservation review because the work is interior and not visible from the public right-of-way.
The bath remodel scenarios that do trigger conservation review:
- A new plumbing vent stack that exits through an exterior wall visible from the street
- A new exterior window installed during the remodel (rare on baths, more common when a primary bath is being expanded into an exterior closet or adjacent room)
- Any exterior siding, masonry, or trim work that becomes necessary to support the interior change
- A skylight added over the bath
If your project triggers any of the above, the conservation review is a separate workflow. It adds 2 to 4 working weeks to the project timeline. We design around it whenever we can.
If you do not know whether your property is inside the overlay, the Town's Planning and Zoning office can confirm with the street address. We check before we sign a contract, not after.
Step-by-step permit application
Homeowner DIY route
You can file as a homeowner if you are performing the work yourself on your primary residence. Most Highland Park bath remodels are not homeowner-DIY projects because they require a licensed master plumber and licensed master electrician for the sub-trade work, and those professionals usually pull their own permits.
If you are filing the building permit yourself:
- Download the residential permit application from the Town of Highland Park website
- Prepare project plans showing existing conditions, proposed changes, and dimensions
- Compile specifications for fixtures, finishes, and materials
- Attach proof of contractor licensing and insurance for any sub-trades
- Submit the packet to the Building Inspection Department at 4700 Drexel Drive
- Pay the fee at submission
- Wait for plan review (5 to 10 working days typical)
- Receive the approved permit and schedule the rough-in inspection before any concealed work is closed up
Contractor-filed route (most common)
The contractor files all required permits on your behalf, pays the fees, and includes the cost in the contract. The permit number is issued in the contractor's name with your property address. The permit number should be written into your contract so you can verify it directly with the Town.
We recommend the contractor-filed route for any project beyond a simple fixture replacement. The reason is not that homeowners cannot file. The reason is that the inspector relationship and the packet completeness shortcut weeks off the timeline, and the contractor doing the work has the documentation the Town wants to see.
Common rejection reasons and how to avoid them
These are the reasons Town of Highland Park most often kicks a residential permit packet back for resubmission. Each one costs a week. Each one is avoidable.
Incomplete plans. Plans that show "new shower" without dimensions, wall thickness, fixture rough-in locations, and a clear before-and-after layout. The Town wants to see what is changing, not just what is being installed.
Missing license or insurance documentation. Every sub-trade pulling its own permit needs current Texas master license credentials and a current certificate of insurance on file. If the plumber's insurance lapses on the day of submittal, the permit kicks back.
Wrong jurisdiction. Filing a permit for a University Park address with the Town of Highland Park, or vice versa. Happens more often than you would expect when the contractor is unfamiliar with the line between the two municipalities.
Conservation overlay missed. Submitting the building permit packet without acknowledging that the property is in the overlay and the work triggers review. The Building Department flags this on intake and routes the packet to Planning and Zoning, but the project sits while it is being routed.
Energy code documentation missing. Texas residential remodels above a certain scope require energy code compliance documentation (insulation, ventilation, fixture flow rates). For a bath remodel, this usually means specifying low-flow toilets and showerheads and any exhaust fan ventilation rate. A missing sheet costs a week.
Inspection schedule
A typical Tier 2 full bath remodel has two scheduled inspections inside the Town.
Rough-in inspection. After demo and framing changes, after plumbing and electrical rough-in is complete, before insulation and drywall close up the walls. The inspector verifies that drain, vent, supply lines, and electrical work meet code. We schedule this when the rough-in is genuinely complete, not "almost complete," because a failed rough-in inspection re-starts the scheduling clock.
Final inspection. After all finish work is complete, all fixtures are installed, all electrical is energized, and the bath is ready for daily use. The inspector verifies that GFCI protection is in place, ventilation works, fixtures operate, and the room matches the approved plans. The final inspection releases the permit, which closes the project from the Town's perspective.
Some larger Tier 3 projects also schedule an electrical service inspection (if a new circuit panel is involved) and a mechanical inspection (if HVAC ductwork changed). Most bath remodels do not need these.

Find My ProsFrequently Asked Questions
Do I need a permit for a bath remodel in Highland Park, TX?
Yes, a permit is required for most bathroom remodels in Highland Park, TX. Any project involving a full gut, plumbing relocation, electrical changes, or framing modifications needs a permit from the Town of Highland Park Building Inspection Department. Purely cosmetic updates that do not alter systems generally do not require one.
In Highland Park, the need for a permit depends on your project's scope. You must file with the Town of Highland Park Building Inspection Department for significant alterations. This includes any work that changes the structure, such as framing modifications, or systems, like relocating plumbing or altering electrical wiring. A full gut remodel always requires this step.
However, simple cosmetic changes are often exempt. For example, if you replace a vanity in its original footprint without touching the existing plumbing or electrical connections, a permit is typically not necessary. The key distinction is whether the work goes beyond a surface-level refresh.
Who files the permit, the homeowner or the contractor?
Either the homeowner or the contractor can file the permit. Most homeowners have their contractor file because sub-trade permits for plumbing and electrical work must be submitted by licensed master tradespeople. A contractor who files in Highland Park weekly will also move the packet through plan review faster than a first-time filer.
While both filing routes are allowed, the contractor-filed path is more common. A key reason is that sub-trade permits for specialized work, such as plumbing or electrical, must be submitted by the licensed master plumber or master electrician performing the work. This requirement often makes it simpler to have the general contractor handle the entire permit package. Furthermore, a contractor who regularly files permits in a specific area like Highland Park will be more familiar with the local plan review process, potentially speeding up approvals compared to a homeowner filing for the first time.
How long does it take to get a bath remodel permit approved in Highland Park?
In Highland Park, a bath remodel permit with a complete and correct application packet is typically approved in 5 to 10 working days. The timeline can extend by an additional 1 to 4 weeks if the packet is incomplete, is missing license documentation, or if the project triggers a conservation district review.
The expected 5 to 10 working day approval timeline for a bath remodel in Highland Park is contingent on submitting a clean packet. Any issues with the application will cause delays.
Common problems that extend the process include incomplete paperwork and missing contractor license documentation. Furthermore, projects that fall under conservation district review require extra steps, adding to the wait. Any of these factors can lengthen the approval period by 1 to 4 weeks.
How much do Highland Park bath remodel permits cost?
In Highland Park, a typical Tier 2 full bath remodel permit bundle costs between $400 and $1,200. This total covers the necessary building, plumbing, electrical, and mechanical permits. The final fee depends on the project's declared value and which specific sub-trade permits are required for the work.
The total permit cost for a full bath remodel within the Town of Highland Park varies based on project specifics. The $400 to $1,200 range accounts for the combined fees from several permits, including building, plumbing, electrical, and mechanical. Not every project will require all sub-trade permits, which affects the final price. A higher declared project value will also result in a higher total permit fee, pushing the cost toward the upper end of that estimate.
Is my Highland Park house in the conservation district overlay?
Not every Highland Park house is in the conservation district overlay, as it applies only to specific streets and properties. To confirm your home's status, contact the Town's Planning and Zoning office at 4700 Drexel Drive. Most interior work, like bath remodels, does not require conservation review.
The conservation district overlay is not a blanket designation for the entire Town of Highland Park. Instead, its rules apply to a select group of streets and individual properties. For a definitive answer regarding your specific street address, you must consult the Town's Planning and Zoning office, located at 4700 Drexel Drive.
It is important to note that the review process generally focuses on exterior changes. For this reason, most common bath remodels do not trigger a conservation review because the work is entirely interior.
What happens if my contractor does the work without a permit?
Work done without a permit can result in the Town issuing a stop-work order, levying fines, and requiring retroactive inspections. The larger issue often arises during resale, as unpermitted work can appear on inspection reports, negatively impact appraisals, and create complications with both title and property insurance for the new owner.
When work is done without a permit, the Town can halt the project with a stop-work order, impose fines, and demand that finished work be opened up for a retroactive inspection. This process can be expensive and disruptive.
The more significant challenge, however, often arises when you sell the home. Unpermitted construction typically shows up on inspection reports, which can kill an appraisal. This discovery also creates serious issues for title searches and for the buyer's ability to obtain homeowner's insurance, potentially derailing the sale.
Does the Town of Highland Park accept online permit applications?
The Town of Highland Park may accept online permit applications, but the preferred method depends on your specific packet type. The Building Inspection Department describes its current submission process on the town's official website. You should call the department before your first filing to confirm the correct procedure for your documents.
Applicants should always check the official Town of Highland Park website for the most current information from the Building Inspection Department. Because the preferred submission method can differ between an online portal and an in-person filing, it is important to verify the correct process. A preliminary phone call to the department before you submit your packet for the first time will ensure you are following the proper guidelines for your specific application type.
What is the difference between Highland Park and Dallas city permits?
Highland Park and Dallas permits are different because they are separate jurisdictions, each with its own building department, forms, fee schedules, and inspectors. The Town of Highland Park has its own department in Town Hall at 4700 Drexel Drive, while the City of Dallas permit office does not handle anything inside Town limits.
Because they are separate jurisdictions, the two permitting processes are entirely distinct. Projects within the Town of Highland Park require filing with its municipal building inspection department, located in Town Hall at 4700 Drexel Drive. The City of Dallas permit office is a separate authority and does not handle any permits for construction inside the Town's limits. This separation means applicants must use different forms, pay according to different fee schedules, and work with different inspectors depending on the project's location.
Do I need a separate permit if I am adding a heated floor in my bath?
Yes, a permit is required for a heated floor because it is considered electrical work. If your bathroom remodel already includes an electrical permit for other changes, like new circuits or lighting, the heated floor is covered by that filing. If it is the only electrical work, a standalone permit is necessary.
Installing a heated floor mat is classified as electrical work and therefore falls under the scope of an electrical permit. This ensures the installation meets all safety and code requirements.
For a larger bathroom remodel that already requires an electrical permit for tasks such as relocating lighting or changing circuits, the heated floor installation can be included in that same filing. You do not need a separate, additional permit for the floor in this case.
However, if the heated floor is the only electrical modification being made in the project, you must obtain a standalone electrical permit specifically for that work. This ensures proper inspection and approval of the installation.
Can my contractor start demo before the permit is approved?
No, a contractor cannot start demolition before the permit is approved. Proceeding without an approved permit in hand exposes your project to a stop-work order from the city. While demolition of finishes can sometimes begin under an issued building permit, that permit must first be officially approved and present on-site.
A contractor who wants to start demo before the permit is approved is creating a significant risk for your project. If work is discovered, the city will issue a stop-work order, halting all activity and potentially causing fines and major delays. Even seemingly minor work, like removing interior finishes, requires the building permit to be issued.
For this reason, our policy is absolute. We do not start any demolition until the permit is fully approved and in our possession. This approach protects your project from preventable and expensive complications.
