The Town of Prosper’s Building Inspections Division issues building and trade permits, and every application, payment and inspection request goes through the Citizens Self-Service (CSS) portal. A new home costs $1.00 per square foot, garage and porches included, plus a $300 application fee, and the first review round takes about ten business days.
What requires a permit in Prosper?
A homeowner doing their own work needs the same permits a contractor would. The Town’s homeowner list:
Permit required
- Additions, including enclosing a back patio or finishing attic space
- Patio covers, pergolas, arbors and sheds; every accessory building needs a permit whatever its size
- Re-roofing
- Fences, unless less than 16 linear feet is replaced with like materials
- Driveways, sidewalks, patios and any section of Town sidewalk
- Electrical work, including solar panels, EV chargers, panels and circuits
- Water heaters, water softeners and whole-house filters
- Air handler and condenser replacements and mini-split systems
- Retaining walls over 48 inches
No permit
- Flooring, painting, cabinets, countertops and trim
- Landscaping, garden walls, edging, pavers and French drains
- Low-voltage wiring under 25 volts and 50 watts
- Playground equipment at single-family homes
- Detached decks up to 200 sq ft and 30 inches high that do not serve an exit door
- Retaining walls under 48 inches with no surcharge
- HVAC repairs that only replace parts
Commercial projects need an approved site plan, façade plan and address plan from the Planning Division before construction plans are submitted. The Town does not enforce HOA covenants, so check those separately.

Get a free quote →Commercial valuation uses the latest ICC Building Valuation Data for the gross floor area, less 20% for a shell building or 50% for a finish-out. The minimum permit fee is $100, an expired permit costs half the original fee to reactivate for 30 days, and permits under $350 and plan review fees are not refunded. For example, a 3,000 sq ft home including its garage pays $3,000 plus the $300 application fee.
Contractors and trade permits in Prosper
Every contractor working in Prosper must register with the Town in CSS, at $100 a year, and the public can search registered contractors there. On a new home or larger project the general contractor pulls the permit and lists its registered electrical, mechanical and plumbing subcontractors; a subcontractor needs its own permit only for work after the main permit is finaled. A hired contractor, not the homeowner, must pull the permit for the work it performs.
Homeowners with a homestead exemption may do their own water heater or irrigation work after filing the Homestead Homeowner’s Affidavit, but an irrigation system still needs a licensed, Town-registered backflow tester. Replacing a water heater always needs a permit; if it is an emergency outside office hours, the plumber gets the permit the next business day. Solar arrays, generators and meter bases have their own handouts, and generator and battery systems may use the state’s third-party review forms for home backup power.
Rather talk it over?
Call 1-855-478-4290 →What to submit for a new house in Prosper
File a “Residential New” record in CSS with:
- A septic (OSSF) permit if the lot uses septic: from Collin County Development Services in the Collin County part of town; TCEQ lists no local septic agent for the Denton County part, where its Region 4 office in Fort Worth (817-588-5800) issues the permit
- Site plan and energy report, plus the NCTCOG residential energy compliance path form
- Engineer-sealed plans: engineer’s letter, foundation, shear walls, ceiling and roof framing, and floor system where used
- Architectural plans: floor plans, electrical plans, elevations and roof plan
Exterior walls within 5 feet of a property line need a 1-hour fire rating. A fire sprinkler system is required if the home is three stories or more, has 5,500 sq ft or more of air-conditioned space, or is taller than 35 feet, and the Town requires a pressure-reducing valve on every new home. Plan review takes five business days for minor permits such as pools, accessories, signs, fences and flatwork, ten business days per round for homes and remodels, and twenty business days for a first commercial review (ten for later rounds).

Create a CSS account; contractors also complete their annual Town registration there.
The Forms & Submittal Handouts page has a handout for each permit type, from new houses and re-roofs to pergolas, sports courts and pools.
Site, façade and address plans must be approved by the Planning Division before building plans go in.
Upload the documents in CSS; a permit technician checks the submittal and routes it to a plans examiner.
Corrections are handled in the same record; significant changes after approval need a restamp, which can take up to ten business days.
A permit lapses if work does not start within 180 days or stops for 180 days between approved inspections.
Inspections in Prosper
Request inspections in CSS before 7:00 a.m. on the day you want the inspection; later requests roll to the next business day. Any balance due on the permit blocks requests. Cancel by email or phone with the permit technicians or the inspector; cancelling after the inspector reaches the site costs a re-inspection fee. Results are posted in CSS, and inspectors are usually in the office from 7 to 8 a.m. and 3 to 3:30 p.m. for questions.
For a new home, a third-party pre-pour report must be uploaded before the foundation inspection, and the engineer’s letters for the foundation, framing and wind bracing, the energy reports, and passed irrigation, fence and Public Works inspections all come before the building final. A re-inspection fee can be charged if the job is not ready, the address is not posted, the site is not kept clean or the gas test gauge is missing. Prosper does not issue certificates of occupancy for homes; a home may be occupied only after all required inspections have passed.
Texas building code
Texas has no single statewide building code: state law makes the International Residential Code the base code for homes in cities and the International Building Code the base for commercial buildings, with each city choosing the edition and its own amendments, while the National Electrical Code and the energy code apply statewide. Outside city limits most counties issue no building permits for homes. Texas building code rules
