Do you need a building permit in Adams County, Colorado?

Yes. Unincorporated Adams County requires a building permit before you construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure, and for specified electrical, gas, mechanical, plumbing and sign work1. Permitted construction also requires inspections based on the approved scope of work, and the applicant must schedule them at least 48 hours ahead2. Colorado law allows counties to adopt building codes and require permits outside incorporated cities and towns12. State law permits an exception for structures used solely to shelter farm implements, products, livestock or poultry, but we could not confirm that Adams County adopted that exception; ask the Building Safety Division before treating an agricultural building as exempt12.

Who issues building permits in Adams County, and how do you reach them?

Adams County's Building Safety Division, reachable through the county's One Stop Permitting Center at 720.523.6800, handles building permits and inspections for unincorporated Adams County13. Applications go through the county's E-Permit Center, with a site plan, architectural plans and details, and mechanical, electrical and plumbing plans where applicable; contractors must be identified and registered before issuance14. Adams County uses the 2024 editions of the International Codes, adopted April 21, 2026 and effective July 1, 202615. Colorado uses local control for most land-use and building-code decisions, so incorporated municipalities may have their own permitting authority and process1615.

Does Adams County have zoning?

Yes. Adams County zones its unincorporated territory under Development Standards and Regulations adopted by the Board of County Commissioners35. The standards are district-specific: an Agricultural-1 case identifies a 100-foot front setback for an accessory structure, while an Agricultural-3 case identifies a 750-square-foot maximum accessory dwelling unit size1718. Those examples do not establish the rule for another district, so confirm the parcel's zoning and applicable dimensional standards with Community & Economic Development. Colorado law allows county zoning to regulate building location, height, bulk, lot size and land use in unincorporated territory19. Land division is also regulated under state law, with exceptions that include certain resulting parcels of at least 35 acres20.

How do septic permits work in Adams County?

The Adams County Health Department's Water Quality Program handles septic, or onsite wastewater treatment system (OWTS), permits and inspections for properties not served by public sewer4. Installation, expansion, major repair and minor repair applications require a permit application, septic design and soils report6. A narrow exception covers work that does not add, repair, replace, expand, mitigate or abandon a septic tank, leach field, sewer line or effluent line; examples include replacing risers, lids and distribution boxes21. A final inspection is required before use, and the system generally cannot be covered first22. About 57.1% of Adams County soils are rated as not severely limited for a conventional drain field, so parcel-level soil evaluation still matters7. Buildings without public sewer cannot receive building or occupancy approval until the OWTS permit and final inspection are complete23.

Can you live in an RV or tiny home on your land in Adams County?

We could not confirm Adams County's rule for residential or long-term RV occupancy on private land, so ask Community & Economic Development about the parcel and proposed use before relying on an RV during construction5. Colorado's state-park camping rules apply to land controlled by Colorado Parks and Wildlife, not private-land occupancy24. A tiny home approved under Colorado Division of Housing standards may be used for long-term occupancy, but it must still satisfy local land-use requirements10. A HUD-code manufactured home likewise may be installed only where local zoning allows it11. In the Agricultural-3 district, one county case identifies a 750-square-foot maximum for an accessory dwelling unit, but that district-specific example does not answer the rules for a primary tiny home or another zoning district18.

Building a home in Adams County: the steps, in order

  1. Confirm the parcel's zoning district, permitted use and setbacks with Adams County Community & Economic Development35.
  2. Submit the building application and required plans through the E-Permit Center; identify registered contractors before permit issuance14.
  3. Design to the 2024 International Codes now in effect in unincorporated Adams County15.
  4. If the parcel lacks public sewer, send the septic application, design and soils report to the Health Department6.
  5. For a new or replacement well, apply to the Colorado Division of Water Resources; review of a complete application may take up to 49 days8.
  6. Obtain a CDOT access permit if the driveway connects directly to a state highway25.
  7. Schedule county building inspections at least 48 hours ahead and complete the septic final inspection before use222.

What to check before you buy land in Adams County

Adams County runs semi-arid and dry: about 15.6 inches of precipitation a year, with roughly 16.3% of years in severe drought, so water planning matters more here than in wetter counties2627. Farmland runs about $2,918 an acre and a typical home is valued around $486,462, with an effective property tax rate near 0.6% and a median annual tax bill around $2,77028293031. The terrain is gentle almost everywhere, 98.2% of land at 15% slope or less, but lightly wooded, only 5.9% forest cover, so expect open, buildable ground with little natural windbreak3233. Confirm your parcel's zoning district before you commit, since Adams County zones its unincorporated land directly and rules vary by district3. If the parcel isn't on a public sewer, check septic suitability with the Health Department first: 57.1% of county soils are rated free of severe limitations for a conventional drain field, which is favorable, but the rest may need an engineered system7. Development in a floodplain needs to meet local regulations that must equal or exceed FEMA's National Flood Insurance Program criteria, so check flood zone status with the county before you buy34. If you're weighing a short-term rental, know that Colorado has no statewide rulebook for that; Adams County's own board of commissioners sets any licensing and fees35.

Watch-outs

  • We could not confirm whether Adams County allows an unlicensed owner to pull a permit as an owner-builder; ask the Building Safety Division before planning to self-perform9.
  • We could not confirm Adams County's private-land RV occupancy rule or a general minimum dwelling size; ask Community & Economic Development about the parcel and proposed use5.

Over-appropriated / declining

Household wellExempt up to a limit

A household obtains water via a permit-exempt small-capacity well (15 gpm) under CRS 37-92-602 outside designated basins or CRS 37-90-105 inside them; on a 35-acre-plus lot limited outside/stock/1-acre irrigation is allowed.

Limit: Household-use-only well: 15 gpm, ≤0.33 acre-ft/yr, indoor only. Domestic well on a 35+ acre tract: 15 gpm, ≤1 acre-ft/yr.
