Allen issues building permits through the Building and Permitting Division of the Community Development Department at 305 Century Parkway. Allen is one of the fastest-growing communities in Collin County, and its permitting operation is built around residential improvement volume — pools, covered patios, accessory structures, and additions — alongside commercial development.
Allen writes its own amendments into the residential code rather than adopting a model code clean, and those amendments are where the binding local requirements live. A package that cleared Plano, Frisco, or McKinney does not automatically clear Allen.
Applies inside Allen city limits. Adjacent Collin County municipalities — Plano, Frisco, McKinney, Wylie, Fairview, Lucas, and Parker — each run their own building departments with their own amendments. Confirm the parcel before filing.
Allen amends the model code’s exemption list. The city rewrites IRC R105.2 rather than adopting it as published — for example, replacing a defective concealed trap, drain, water, soil, waste, or vent pipe is treated as new work requiring a permit and inspection, even though simply stopping a leak is exempt. Read the amended list, not the model text.
What requires a permit in Allen?
Allen requires a permit for construction, alteration, and repair work that affects structure, systems, or occupancy, and it enforces an amended exemption list rather than the model code’s. The distinction between a repair and a replacement carries real weight here.
Permit required
- New residential and commercial construction, additions
- Structural and load-bearing alterations
- Pools, spas, and pool barriers
- Covered patios, patio covers, and accessory structures
- Replacing a defective concealed trap, drain, water, soil, waste, or vent pipe
- Electrical, plumbing, and mechanical alterations
- Reroofing and exterior envelope work
- Change of occupancy or use
Exempt under the amended list
- Painting, wallpapering, tiling, and floor coverings
- Cabinet and countertop work
- Water tanks supported directly on grade at or under 5,000 gallons where the height-to-width ratio does not exceed 2:1
- Stopping a leak in a drain, water, soil, waste, or vent pipe, short of replacement
Allen building department: who handles permitting
The Building and Permitting Division within Community Development handles plan review, permit issuance, and inspections for everything inside Allen city limits. Plan review correspondence and inspection workflow changes route through a dedicated plan review mailbox rather than a general city line.
Allen publishes packet-based submittal requirements by project class — a commercial construction packet, residential packets, and standalone forms — so the packet you complete determines the document set the reviewers expect.

Allen permits: record types and what each covers
A building permit is one record among many. Allen issues work under separate record types and defines the boundaries with its own code amendments rather than the model text, so the record type question and the "does this even need a permit" question are answered from the same local document.
Residential permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New construction | New dwellings, additions, and accessory structures over the exempt threshold | Full plan review (structural, energy, zoning) | Valuation-based |
| Renovation / alteration | Structural or load-bearing changes, layout changes, substantial repair | Plan review scaled to scope | Valuation-based |
| Reroof | Roof covering replacement and most major roof repair | Product approval review; dry-in and nail-off inspections | Valuation or squares |
| Solar photovoltaic | Rooftop or ground-mount PV installation or replacement | Structural plus electrical review | Flat or system-size based |
| Solar thermal | Passive water heating or pool heating systems | Plumbing and structural review | Flat or per-permit minimum |
| Electrical | Service changes, panel upgrades, new circuits, most wiring alterations | Trade review; filed against the building permit | Per-permit minimum or per-device |
| Plumbing | New piping, repipes, water heaters, fixtures, gas piping | Trade review; filed against the building permit | Per-permit minimum or per-fixture |
| Mechanical / HVAC | Changeouts that are not like-for-like, ductwork, refrigeration | Trade review; filed against the building permit | Per-permit minimum or per-unit |
| Windows and doors | Replacement units and opening protection | Product approval review for wind-borne debris | Valuation or per-opening |
| Pool and spa | In-ground and above-ground pools, spas, barrier and enclosure work | Plan review plus barrier and electrical bonding | Valuation-based |
| Fence and accessory | Fences, sheds, decks, and carports over the exempt threshold | Zoning plus structural where applicable | Flat or valuation-based |
| Demolition | Full or partial demolition of a structure | Utility disconnect verification required | Flat |
Commercial permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New construction | Ground-up commercial, industrial, and multifamily | Full multi-discipline plan review | Valuation-based |
| Tenant improvement | Interior build-outs and suite fit-ups | Plan review across affected disciplines | Valuation-based |
| Renovation / alteration | Structural, envelope, or system changes to an existing building | Plan review scaled to scope | Valuation-based |
| Change of use | Converting a building from one occupancy classification to another | Zoning, life-safety, and accessibility review | Valuation or flat |
| Reroof | Commercial roof covering replacement | Product approval review plus fire review where applicable | Valuation or squares |
| Solar photovoltaic | Commercial rooftop, carport, and ground-mount PV | Structural, electrical, and often fire review | Valuation or system-size based |
| Electrical | Service, distribution, and branch circuit work | Trade review | Valuation or per-device |
| Plumbing | Supply, waste, vent, and gas systems | Trade review | Valuation or per-fixture |
| Mechanical / HVAC | Rooftop units, ductwork, exhaust, and refrigeration | Trade review | Valuation or per-unit |
| Fire protection | Sprinkler, standpipe, alarm, and suppression systems | Fire prevention plan review | Valuation or per-device |
| Sign | Wall, monument, and illuminated signage | Zoning plus electrical where illuminated | Flat or per-sign |
| Demolition | Full or partial commercial demolition | Utility disconnect and environmental clearance | Flat or valuation-based |
Residential
- Single-discipline review in most cases
- Master permit with trades filed against it
- Owner-builder route exists but carries statutory affidavits
- Product approval drives roofing and opening protection
Commercial — multi-discipline
- Concurrent review across building, fire, and zoning
- Signed and sealed plans across every affected discipline
- Accessibility and life-safety review attach to change of use
- Impact and concurrency fees can apply on top of permit fees
Solar permits in Allen
Solar is permitted as its own record type in most Texas jurisdictions rather than rolled into a general building permit, and residential and commercial photovoltaic are usually separate records with different document sets. Solar thermal — passive water and pool heating — is a third, distinct record.
A photovoltaic submittal is reviewed on two tracks at once: structural (roof load path, attachment spacing, uplift) and electrical (conductor sizing, rapid shutdown, point of interconnection). A single-line diagram and a signed and sealed structural attachment detail are the two attachments most often missing on a first submittal.
Texas HOA law is narrower than most installers assume. Under Tex. Prop. Code §202.010 a property owners' association cannot prohibit a solar energy device outright, and any dedicatory provision that does is void — but the statute expressly preserves the association's right to require prior architectural approval and to impose placement and appearance conditions. Approval cannot be unreasonably withheld, and conditions that cut estimated production materially are not enforceable. Practically: get the HOA submittal moving in parallel with the permit rather than treating it as optional.
Texas SB 1202 changed this materially on September 1, 2025. Codified at Tex. Local Gov't Code §247.0025, it lets authorized third parties — licensed engineers, electrical inspectors, and Texas master electricians — perform the plan review and inspections for a home backup power installation instead of the jurisdiction. The definition covers generators, energy storage systems, and associated equipment serving a one- or two-family dwelling at 600 volts or less. Construction may begin on submission of the notice, the third party has 15 days to report results, and the regulatory authority must issue the approval on a short statutory clock. Jurisdictions that process work this way do not review or inspect it, and responsibility for code compliance sits with the third-party reviewer and the contractor of record. Note the boundary: it is a backup-power provision, so a straight grid-tied photovoltaic array with no storage is not automatically inside it, and separate electrical or plumbing permits are still generally required for service release. Confirm how Allen is administering SB 1202 before assuming either path.
Utility interconnection runs parallel to the building permit, not inside it. Permission to Operate is issued by the utility after the final electrical inspection clears, and in deregulated territory the interconnecting utility is the wires company rather than the retail provider.
Roofing permits in Allen
A roof covering replacement requires a permit in most Texas municipalities. Repairs below the local threshold may not, but the threshold is scope-specific and set locally — confirming it with the building department before tear-off is cheaper than an after-the-fact permit.
Texas has no statewide product approval system, so there is no central listing to check a roofing product against. Compliance runs against the code edition the jurisdiction has actually adopted and the local amendments layered on top of it. Those amendments are where the binding requirements live, and they change from city to city inside the same county.
Texas Department of Insurance windstorm certification — the WPI-8 process — applies only in the designated seaward counties along the Gulf. Allen is not a seaward county, so WPI-8 certification does not attach here and roofing contractors licensed for inland work do not need TDI appointment for this jurisdiction.
Hail is the governing weather risk across most of inland Texas, not wind. Impact-resistant Class 3 and Class 4 shingles carry insurance premium credits from most carriers, and under Tex. Prop. Code §202.011 a property owners' association cannot prohibit shingles that are wind or hail resistant, or that improve energy efficiency, provided they otherwise match the roof's appearance requirements.
Reroof inspections are typically sequenced by the jurisdiction, commonly a decking or nail-off inspection before the covering goes down and a final afterward. Covering the deck before the required intermediate inspection means tearing it back open.
Texas has no statewide building code and no statewide general contractor license. The code edition and the amendments that bind your submittal are adopted locally, and contractor registration with the jurisdiction is frequently the gate that has to clear before a record type can even be filed. On commercial work, projects over the statutory threshold also register separately with TDLR for Texas Accessibility Standards review, which runs outside the building permit entirely.
Allen sits in Collin County in the North Texas hail belt, roughly 105 mph ultimate design wind speed under the adopted code and nowhere near a coastal windstorm requirement. Hail is the loss driver, and reroof volume across Allen spikes after spring storm cells rather than tracking construction cycles.
Allen permit cost and fees
Allen building permit fees follow the city fee schedule and scale with the class and valuation of work, with separate trade permit fees and separate records for pools, patio covers, and accessory structures.
Because Allen carries local amendments, two projects with identical scope can carry different document requirements on either side of a city line, which affects review effort more than fee amount. Confirm current figures before budgeting.
| Fee component | How it works |
|---|---|
| Building permit | Scales with project class and valuation |
| Trade permits (E / P / M) | Separate fee per trade, filed by the licensed contractor |
| Pool, patio cover, accessory | Separate records with separate fees |
| Re-inspection | Charged when a checkpoint fails and is re-requested |
| Work without a permit | Exposes the owner to penalties and stop-work orders |

Allen trade permits
Electrical, plumbing, and mechanical work each need their own permit pulled by the state-licensed contractor for that trade. Texas licenses the trades at state level and does not license general contractors, so trade licensure and city registration carry the compliance weight.
Electrical
Service and panel work, new circuits, solar PV, and EV charging circuits — performed by a TDLR-licensed electrician.
Plumbing
New plumbing, repipes, water heaters, fixtures, gas piping, and the pipe replacement scopes Allen treats as new work — performed by a TSBPE-licensed plumber.
Mechanical / HVAC
Installations, non-like-for-like changeouts, ductwork, and venting — performed by a TDLR-licensed mechanical contractor.
Specialty
Pools and spas, patio covers, accessory structures, signs, and demolition each run their own record and review path.
Allen permit application: how to apply step by step
Check the Allen Development Code and the city’s amended exemption list rather than the model code. Call (214) 509-4160 for borderline scopes.
Allen publishes submittal packets by project class. The packet defines the document set reviewers expect.
A scaled site plan showing lot boundaries, existing structures, proposed improvements, setbacks, driveways, and easements is required for most residential work.
File through the city with the completed packet, plans, and contractor licensure evidence for each trade.
Respond to plan review comments, pay fees, and take the permit. Post it on site before work starts.
Schedule the sequence, using bpplanreview@allentx.gov to add or remove inspections, and clear the final — observing the 7 a.m. to 10 p.m. construction hours throughout.
Inspections in Allen
Allen runs the standard inspection sequence — foundation, framing, rough-in across the trades, insulation, and final — with the specific checkpoints set by the permit workflow rather than assumed from scope.
Inspection workflow changes are handled by email to bpplanreview@allentx.gov. Adding a missing inspection late is far cheaper than failing a final because a required checkpoint was never in the workflow.
Construction is permitted between 7 a.m. and 10 p.m., seven days a week. Work outside those hours is a code enforcement matter separate from the permit itself.

Frequently asked questions
Who issues building permits in Allen?
City of Allen Community Development Department issues building permits for everything inside Allen city limits, handling plan review, permit issuance, and construction inspections. Work outside the city limits falls to Collin County, and Texas counties have sharply limited building authority in unincorporated areas.
How do I get a permit in Allen?
Confirm the scope triggers a permit and that zoning allows it, prepare the plan set and site plan, file through Allen permitting portal with contractor licensure in place, respond to plan review comments, pay fees and take issuance, then run the inspection sequence through final. Contractor credentialing is the step most often missed and it blocks everything downstream.
What codes apply in Allen?
Texas has no mandatory statewide building code. Municipalities adopt and amend model codes themselves, so Allen enforces I-Codes with Allen amendments. The local amendments are where the binding requirements live, and they differ from neighboring cities working off the same model code. Confirm the current adopted editions with the department before designing to a specific one.
Does Allen follow the standard code exemption list?
No. Allen amends the residential code’s exempt-work section rather than adopting it as published. The most consequential change for trades: stopping a leak is exempt, but if a concealed trap, drain, water, soil, waste, or vent pipe becomes defective and has to be removed and replaced with new material, the city treats that as new work requiring a permit and inspection. Read the amended list.
What are the construction hours in Allen?
Construction is allowed between 7 a.m. and 10 p.m., seven days a week. That is broader than many metroplex cities on weekend work but firm at both ends. Hours are enforced separately from the permit itself, so a valid permit does not authorize work outside the window.
Which Collin County cities issue their own building permits?
Plano, Frisco, McKinney, Wylie, Fairview, Lucas, Parker, Murphy, and the county’s other incorporated municipalities each run their own building departments with their own code amendments. Allen permits only inside Allen city limits. Collin County itself has limited building authority in unincorporated areas and routes development questions through its own Development Services group — confirm the parcel before filing.
Do I need a permit to install solar panels in Allen?
Yes. Photovoltaic installations in Allen are permitted under a dedicated solar record type reviewed on both a structural and an electrical track. Solar thermal — passive water and pool heating — is a separate record. Under Tex. Prop. Code §202.010 a homeowners' association cannot ban a solar energy device outright, but it may still require prior architectural approval and impose reasonable placement conditions, so run the HOA submittal alongside the permit. Since September 1, 2025, Tex. Local Gov't Code §247.0025 (SB 1202) also permits third-party plan review and inspection of home backup power installations — generators and energy storage for one- and two-family dwellings at 600 volts or less — in place of jurisdiction review. Utility interconnection and Permission to Operate still run in parallel.
Does a roof replacement require a permit in Allen?
Yes, in most cases. A roof covering replacement requires a permit in most Texas municipalities including Allen, though minor repairs can fall below the local threshold. Texas has no statewide product approval system and no central product listing, so compliance runs against the locally adopted code edition and its local amendments. Hail rather than wind is the governing risk inland, and Tex. Prop. Code §202.011 bars an HOA from prohibiting wind or hail resistant shingles.
What is the difference between a residential and a commercial permit in Allen?
Residential work is generally a single-discipline review filed as a master permit with trades filed against it. Commercial work in Allen runs concurrent review across building, fire, and zoning, requires signed and sealed plans for every affected discipline, and can carry impact and concurrency fees on top of permit fees. Change of use adds accessibility and life-safety review.
Do trade permits need to be pulled separately in Allen?
Yes in most cases. Electrical, plumbing, and mechanical work is permitted separately by the licensed contractor for each trade and filed against the master building permit. Each trade permit carries its own fee and its own inspection sequence.
What happens if I file under the wrong permit type in Allen?
The application is rejected rather than corrected. Allen Permits and Licensing closes the record, the filing is resubmitted under the correct record type, and the review clock restarts from zero. Confirming the record type before filing is the cheapest step in the entire process.
Can I apply for all Allen permit types online?
Largely, yes. Allen publishes submittal packets and forms for online completion and handles plan review correspondence and inspection workflow changes through bpplanreview@allentx.gov. Availability varies by project class, and commercial work runs a heavier packet than residential. Trade contractors must hold current state licensure before a filing will process.
