Bath Remodel Permits in Highland Park, TX: The 2026 Homeowner's Guide

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)

Highland 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:

1. Download the residential permit application from the Town of Highland Park website
2. Prepare project plans showing existing conditions, proposed changes, and dimensions
3. Compile specifications for fixtures, finishes, and materials
4. Attach proof of contractor licensing and insurance for any sub-trades
5. Submit the packet to the Building Inspection Department at 4700 Drexel Drive
6. Pay the fee at submission
7. Wait for plan review (5 to 10 working days typical)
8. 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.
