Codes adopted
Colorado has no statewide-mandated building code edition. Under the Colorado Constitution's home-rule provisions (art. XX, home rule for municipalities since 1902; home rule for counties since 1970), building codes and zoning are an enumerated home-rule charter power, so cities and counties adopt and amend their own construction codes independently — predominantly the I-Codes, with editions and local amendments varying by jurisdiction. The one statewide floor is for energy: HB22-1362 (2022) created the Energy Code Board (jointly appointed by the Colorado Energy Office and the Department of Local Affairs) and requires that, on or after July 1, 2023 and before July 1, 2026, any municipality or county that adopts or updates a building code must adopt and enforce an energy code achieving performance equivalent to or better than the 2021 IECC together with the board's Model Electric Ready and Solar Ready Code (which includes electric-ready, EV-ready, and solar-ready provisions); from July 1, 2026 onward the floor shifts to the board's Model Low Energy and Carbon Code or an equivalent. Electrical and plumbing permitting defaults to the Colorado State Electrical Board and State Plumbing Board (within DORA's Division of Professions and Occupations) — the state issues permits and inspects statewide except in counties/jurisdictions that operate their own certified Electrical or Plumbing Inspection Program, in which case the local program has authority instead. Always confirm the currently adopted code edition, local amendments, and inspection authority (state board vs. local program) with the specific jurisdiction before submitting plans.

Permit types & fees
Residential Building Permit (New Construction)
Required for construction of all new single-family homes, duplexes, townhomes, and other buildings/structures in the Town of Parker, regardless of size (limited exceptions apply to small detached accessory structures). Reviewed by the Town's own Building Division under the codes listed above, with fees set by the Town's Building Permit Fee Valuation Schedule (effective June 15, 2020).
Residential Addition / Remodel / Alteration Permit
Required for additions, decks, structural alterations, kitchen/bath remodels, basement finishes, garage conversions, and similar projects on existing residential structures in Parker.
Electrical Permit
Required for electrical installations, alterations, and upgrades in Parker, governed by the National Electrical Code (2023 NEC in effect through December 31, 2026; 2026 NEC effective January 1, 2027). Standalone residential electrical permits follow a published formula-based fee structure separate from the general valuation-based Building Permit Fee Schedule.
Plumbing Permit
Required for plumbing alterations and upgrades in Parker, governed by the International Plumbing Code (2024 IPC effective June 30, 2026). Parker uses the IPC, not the Uniform Plumbing Code.
Mechanical / HVAC Permit
Required for furnace replacement, water heater installation, and air conditioner installation/replacement in Parker, governed by the International Mechanical Code and International Fuel Gas Code (2024 editions effective June 30, 2026). New-construction HVAC systems are additionally subject to Parker's own Manual J/S/D design and duct-testing requirements.
Re-Roofing Permit
Required for re-roofing on residential, commercial, and multi-family buildings in Parker, per the Town's own Re-Roofing Requirements handout (revised March 14, 2025). Reviewed against the 2021 IRC (Residential) / 2021 IBC (Commercial and Multi-Family) — the specific editions cited by the Town's roofing handout, which predates the broader 2024 I-Code transition effective June 30, 2026.
Solar Photovoltaic (PV) Permit
Required for residential and commercial solar photovoltaic (and solar thermal) system installations in Parker. Reviewed by a Town of Parker Electrical Inspector under the adopted National Electrical Code and International Building Codes. Parker publishes a flat permit/plan-review fee and a specific review-time goal for this permit type.
EV Charger / EVSE Permit
The Town of Parker does not publish a dedicated EV charger/EVSE permit; a dedicated EV charging circuit is permitted as standalone electrical work through the Town's standard Electrical Permit, billed under the same formula-based fee structure (Table 3.2) used for all standalone residential electrical permits — no EV-specific line item exists. Parker's population is well above the 10,000-resident municipal threshold that makes it a 'covered municipality' under Colorado HB24-1173, the statewide EV Charging System Permits law requiring covered jurisdictions to notify applicants of an approval/denial decision within 3 business days by a December 31, 2025 compliance deadline; no published record was found confirming which HB24-1173 compliance path (Colorado Energy Office model code, the Town's own standards, or an opt-out resolution keeping the existing process) the Town adopted.

Tips & gotchas
- AUTHORITY MODEL: The Town of Parker (Douglas County) runs its own Building Division within the Community Development Department — it is a home-rule municipality with an independent building authority, NOT part of a joint/regional department like Colorado Springs' PPRBD or Pueblo's SoCoBD. Parker is on the Colorado DFPC's prequalified-building-department list. The Chief Building Official / Assistant Director of Building is Randy Sale. Source: Town of Parker Staff Directory, https://www.parkerco.gov/directory.aspx?EID=74; Town of Parker Building Division page, https://parkerco.gov/114/Building-Division
- CODE TRANSITION IN PROGRESS: As of this extraction, Parker's full enforcement of the 2024 International Codes (IBC, IRC, IPC, IMC, IFGC, IFC, IECC, IEBC, Swimming Pool and Spa Code, Non-Residential Property Maintenance Code) plus the 2025 Colorado Wildfire Resiliency Code and 2025 Colorado Model Electric Ready and Solar Ready Code begins June 30, 2026. The 2023 NEC remains in effect through December 31, 2026, with the 2026 NEC effective January 1, 2027. Always confirm which edition applies to a given submittal date. Source: https://www.parkerco.gov/445/Building-Codes
- Colorado has no statewide mandatory building code (home-rule state); Parker's own adopted codes and locally-published fee/timeline figures above are the governing facts for this jurisdiction.
- PLAN REVIEW TIMELINE (Town-published, verified): new construction (residential/commercial, tenant finishes, remodels, change of occupancy, multi-family) — 3-5 day completeness review, then 2-4 week initial plan review (excludes weekends/holidays), then ~2 week re-review if needed. Existing residential construction (additions, interior remodel) — average 1-2 weeks for first review; minor projects (basement finish, decks, patio covers) may be only 1-5 working days. Solar PV — an explicit 10-14 business day goal for simple systems. NO standalone-trade-permit (electrical/plumbing/mechanical-only, non-reroof) review timeline was found published distinct from these general tracks — represented as null/unverified with a note on those permit types rather than assumed. Source: https://www.parkerco.gov/457/Obtaining-Permits and https://www.parkerco.gov/1693/Solar-Energy-Systems
- FEE STRUCTURE (Town-published, verified, effective June 15, 2020): Building Permit Fee is valuation-based per a published tiered schedule; Plan Review Fee is 65% of the Building Permit Fee (notably higher than the 28% figure PPRBD uses in Colorado Springs); Use Tax is 1/2 of project valuation x 4.0% (shown elsewhere as separate 3% Parker + 1% Douglas County components on half of project cost); Re-inspection fee is a flat $75.00; additional plan reviews are $75.00/hour. New SFD/Commercial/Multi-Family projects also require an upfront plan-check deposit (SFD $200/model; Commercial/Multi-Family half the estimated plan check fee) which is forfeited toward the plan-review fee if the permit is never picked up. Source: https://parkerco.gov/DocumentCenter/View/736/Fee-Valuation-Schedule and https://www.parkerco.gov/459/Building-Permit-Fees
- Standalone residential Electrical permits use a DIFFERENT, formula-based fee (Table 3.2): $88.00 flat up to $2,000 valuation, then $9.00 per $1,000 (or fraction) plus $88.00 above that — NOT the general Table A valuation schedule used for building permits/new construction. No equivalent standalone flat-fee table was found published for standalone plumbing or mechanical-only permits; those are presumed to follow the same general Fee Valuation Schedule pending direct confirmation from the Building Division.

- SOLAR PV is the most transparently documented permit type in this file: a flat $500 (residential) / $1,000 (commercial) fee 'per State requirements,' plus a specific 10-14 business day review goal — both explicitly Town-published, unlike most other trade permits here.
- ADU (Accessory Dwelling Unit) permit type is DELIBERATELY OMITTED from this file. Colorado's statewide ADU mandate (HB24-1152 / SB24-154) took effect June 30, 2025, but the Town of Parker Council took up Ordinance 1.644 (session of May 5, 2025) asserting home-rule authority to reject the state's one-ADU-per-lot requirement, citing infrastructure capacity (16,161+ existing single-family homes; water/sewer/emergency-services constraints). No final ADU permit process, ordinance number, fee, or standard was found published on parkerco.gov or confirmed via Municode as of this extraction — recovery attempted via parkerco.gov Building Codes/Standards pages, the Land Development Ordinance Administrative Manual (PDF, no ADU content), and Municode's Title 13 Land Development Ordinance (an Angular SPA that did not return content to a static fetch). Chasing this further requires either a live browser session against Municode's JS-rendered LDO or a direct records request to the Town Clerk for the outcome of Ordinance 1.644/1.645. OMITTED per the zero-tolerance data policy rather than invented.
- DEMOLITION permit type is OMITTED. No dedicated demolition permit page, application, checklist, or fee schedule was found published on parkerco.gov (checked Building Permits, Building Permit Fees, When Permits are Required, Forms and Regulations, and Permits and Forms pages). Demolition is referenced only indirectly, via contractor registration classes in the Parker Administrative Code (Building Contractor Class A/B/C registrations each explicitly authorize 'construction, alteration, addition, repair, or demolition' of specified construction types). A verified, demolition-specific permit record (application, fee, or review timeline) could not be confirmed and is omitted rather than invented.
- FENCE / RETAINING WALL is NOT broken out as its own permit type in this file because no dedicated fee schedule, application, or handout distinct from the general Building Permit Fee Valuation Schedule was found published; the applicable thresholds (fences over 6 ft, retaining/block walls over 48 inches require a permit) are documented under the Residential Addition/Remodel permit type above, sourced from the Town's own When Permits are Required page.
- Parker's EZ Permits program (homeowner-focused, Wednesdays 8:30 a.m.-noon by appointment) and EZ Commercial Permits program (small non-structural commercial projects under 1,200 sq ft) are notable homeowner/small-business-friendly features not universal across this corpus's other Colorado jurisdictions.
- Fire permits in Parker are issued separately by South Metro Fire Rescue, not the Town's own Building Division — do not conflate fire-related submittals with the Town's eTRAKiT building permit process.
