Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
N/A for a County-adopted building-code edition. The current official building application expressly states that Washington County does not have a building-code ordinance and that the applicant is responsible for following uniform building codes and current State standards. Colorado Division of Housing rules govern manufactured-home installation; State and health-department permits apply to trade and septic work.
Inspection lane
For ordinary buildings, the County form does not publish a standard inspection-booking process. For mobile/manufactured homes, after the County permit and fees are paid, the County provides the inspector's contact information; the owner must arrange inspection before occupancy. Foundations must be inspected before setting a home, and the State installation insignia is required before occupancy/permanent utilities.
Minor-work playbook
The County application requires a permit for new buildings/structures, additions, remodels, and manufactured homes, but publishes no broad cosmetic or minor-work exemption list. A subdivision exemption may be relevant where a parcel is under 35 acres, but it is a land-use issue rather than a general building-permit exemption. Town jurisdictions may impose separate rules.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
For ordinary buildings, the County form does not publish a standard inspection-booking process. For mobile/manufactured homes, after the County permit and fees are paid, the County provides the inspector's contact information; the owner must arrange inspection before occupancy. Foundations must be inspected before setting a home, and the State installation insignia is required before occupancy/permanent utilities.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.

Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
Washington County Planning & Zoning Department is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact Planning & Zoning/Admin/Finance: (970) 345-2701; fax (970) 345-2702; planning@co.washington.co.us..
N/A; no standard County review or issuance timeline was published. Manufactured/mobile-home placement and inspection must be completed within six months of signing the application according to the County packet.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
