Mobile or Manufactured Home Permit (with Foundation Permit if applicable) in Unincorporated Washington County, Colorado
A separate application (distinct from the general Building Permit) for placing a mobile or manufactured home in unincorporated Washington County. Installation and inspection standards are set by the Colorado Division of Housing (state), not a county-adopted code; the County collects its own permit fee and the state's inspection/insignia fee, arranges the state-required inspection, and — if the unit will sit on a permanent foundation or basement — requires a separate Foundation Permit using the same County-designated inspector.

- Completed Mobile or Manufactured Home Permit Application (Rev. 09-12) — legal description, road/highway access, reason for application (new/addition/alteration/repair/move), type and year built of unit, size, acreage, sewer facility, and water source
- Evidence of the total value of the unit or home attached to the application (used to calculate use tax and the state inspection fee)
- Foundation Permit (Rev. 09-12), obtained separately or alongside this application, if the unit will be set on a permanent foundation or basement — inspected by the same County inspector before the home is set
- Evidence of a water source/well permit and either a Northeast Colorado Health Department (NCHD) septic permit or proof that process has begun
- A temporary permit must be posted on the unit after application and fee payment, per State of Colorado Division of Housing requirements (Division of Housing Resolution 38)
- Placement and inspection must be completed within six (6) months of the date the application is signed

State fee (not retained by the County), described on the form as 'State Inspection and Sticker Fees $435.00' / '48% of value of M-Home' cross-reference; covers state inspection and issuance of the required installation insignia. Two County documents conflict on the amount. (1) The County's general Building Permit Application PDF states this same fee as $415.00 flat, not $435.00. (2) This form's own 'Additional Criteria' breakdown itemizes it as 'Inspection Fee for Inspections as required by State $375.00' + 'State of Colorado Dept. of Housing Insignia... $60.00', which sums to $435.00 (matching the headline figure used here) -- but the same sentence then labels that total as '$415.00... required by the State of Colorado,' an apparent arithmetic error within the document itself ($375 + $60 = $435, not $415). The $435.00 itemized breakdown is used here as the better-supported figure because it reconciles with its own components, and the $415.00 figures in both this form and the general application are flagged as the likely error. The County has not published a correction to either document, so treat $435.00 as the best-available figure, not a certainty.$435.00

Inspection process
- 1
Foundation Inspection (if applicable)
Required before setting the home if it will sit on a permanent foundation or basement; performed by the same County-designated inspector who performs the mobile/manufactured-home inspection
- 2
State-Required Mobile/Manufactured Home Inspection
Arranged directly with the County-designated building inspector after permit issuance; the inspector completes State of Colorado Division of Housing checklist forms. Once satisfactorily completed, an installation insignia sticker is issued and must be placed on the unit as required by the State.

Tips
- Budget for three separate charges, not one: the $100 County permit fee, the $435 state Division of Housing inspection/insignia fee, and 1.5% use tax on the home's declared value — all combined into one 'TOTAL FEES' payment to Washington County on the application worksheet.
- If the home will sit on a permanent foundation or basement, apply for the separate $100 Foundation Permit at the same time — it is not included in the Mobile/Manufactured Home Permit fees.
- Start your Northeast Colorado Health Department well/septic application in parallel — the County requires evidence of that process before finalizing this permit.
- Installation standards (and the checklist the inspector uses) come from the State of Colorado Division of Housing, not a county-adopted building code — Washington County administers the paperwork and fee collection but does not set its own separate manufactured-home standard.

Unincorporated Washington County, Colorado has adopted: No model building code (IBC/IRC/NEC) found published online — see the FAQ below for what governs instead; Manufactured/mobile homes: Colorado Division of Housing state standards apply, not a county-adopted code; County Zoning Resolution is in force but not published online — full scope on this point unconfirmed; HB22-1362 (2022), Colorado's statewide model energy and low-carbon code law, exempts jurisdictions under 2,500 residents. Unincorporated Washington County is roughly 3,060 people -- county total 4,817 per the 2020 Census, minus Akron's 1,757, Akron being the county's only incorporated municipality -- so the population exemption does not apply on its own. The law's model-code mandate attaches only when a jurisdiction adopts or updates a building code, and no affirmatively adopted county building code, energy or otherwise, is published anywhere findable, so there is no trigger event on record. The County's Zoning Resolution is not published online, so treat this as nothing found rather than a certainty that nothing exists. If the County adopts or updates any code, the Model Low Energy and Carbon Code requirement binds any update after July 1, 2026. Confirm current requirements with the County before designing to an energy code.. Local amendments apply — see the Unincorporated Washington County overview page for the full list.
A County-designated building inspector performs the inspection using checklist forms required by the State of Colorado Division of Housing, then the State issues an installation insignia sticker once inspections are satisfactorily completed. The same inspector also performs the foundation inspection if a Foundation Permit applies.
