Do you need a building permit in La Plata County, Colorado?

Yes. Unincorporated La Plata County requires building permits for county-regulated work, with exempt work identified in Building Code Section 105.2; applications go through CityView¹. The Building Division specifically identifies new structures, additions and newly placed mobile homes on unincorporated, non-city, township or Tribal property as work requiring a building permit¹³. The county building-permit rules below apply to unincorporated land; Durango and Bayfield issue their own building permits inside city or town limits¹⁴¹⁵. La Plata County Public Health remains the septic-permit authority countywide³. A conditional agricultural exemption covers structures used solely to shelter agricultural implements, farm products, livestock or poultry; it requires a site plan, construction plans, an owner affidavit and a completed-use inspection¹⁶. Ag Plus approval alone does not qualify a structure, and a later change of use requires a building permit and inspections¹⁶. The county's 2024 building-code family took effect July 1, 2026, while the Colorado Wildfire Resiliency Code took effect June 17, 2026¹⁷. Even work exempt from a building permit must meet applicable property-line setbacks, Animas Valley height limits and floodplain rules¹⁸.

Who is the La Plata County building department, and how do you reach them?

The La Plata County Building Division reviews and issues building permits and performs inspections for unincorporated properties; visit 211 Rock Point Drive in Durango, call 970-382-6263 or use CityView¹³. Building-permit charges follow the county code's fee schedule, while road-impact and fire-impact fees may also apply by location; ask the local fire district about its charge¹⁹. Schedule county building inspections at least one business day ahead because same-day inspections are unavailable²⁰. The county Engineering Department at 1365 Camino Del Rio, 970-382-6363, handles driveway access and work within county rights-of-way²¹. A new single-family home needs a county driveway permit, while direct state-highway access requires a Colorado Department of Transportation access permit²²¹¹.

Does La Plata County have zoning?

La Plata County land-use rules vary by planning district and jurisdiction, so a county address alone does not establish the parcel’s zoning²³. The county rules below apply to unincorporated land; Durango sets its own zoning inside city limits²²⁴. La Plata County Public Health still issues septic permits countywide³. Animas Valley parcels can have additional zoning rules, so confirm the parcel's classification with Planning before designing a project⁴. Additional dwellings may need a land-use permit based on parcel size, and a second dwelling on a parcel under 6 acres generally must share the primary home's electrical meter, water source, OWTS and access unless the parcel is tax-assessed agricultural⁷. Its livable floor area cannot exceed the primary dwelling or 2,000 square feet, whichever is less⁷. These acreage bands govern additional dwellings rather than setting a universal minimum lot size, and the table does not apply in Animas Valley²⁵. Minor subdivisions, including agricultural-exemption subdivisions, require a minor land-use permit; major subdivisions require a major land-use permit²⁶.

How do septic permits work in La Plata County?

La Plata County Public Health regulates and issues septic permits countywide under local OWTS rules, so that authority does not shift to a municipality when municipal building or zoning rules apply²⁷. Reach the Environmental Health OWTS team at 185 Suttle Street in Durango or 970-828-8842²⁸. Obtain a septic permit before constructing, altering or repairing an OWTS; applications may be emailed or delivered to Public Health, and marginal lots may fail because of acreage, steep slopes, shallow bedrock, shallow groundwater or setback deficiencies²⁹. Only about 5.1% of county soils are rated free of severe limits for a conventional drain field, so make the site evaluation an early purchase contingency³⁰. Most septic-served properties require an inspection before sale; exemptions include specified recent final approvals and certain non-arm’s-length, trust or LLC transfers³¹. A continued-use permit carries a $120 nonrefundable administrative fee³². A new-home application must show either a septic permit or the applicable sewer-district tap³³.

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

We could not confirm a county rule allowing or barring long-term RV occupancy or private-land camping in unincorporated La Plata County; ask Planning for a parcel-specific answer⁹. A tiny-home community or manufactured-home subdivision in unincorporated La Plata County requires a major land-use permit, but that rule does not answer whether a single tiny home or a dwelling on wheels is allowed on a particular parcel⁸. A tiny home regulated by the Colorado Division of Housing needs plan approval before construction, must meet state-adopted standards and local zoning, and is certified for its installation site³⁴. A structure used as a long- or short-term rental, or occupied independently from the primary dwelling, requires an ADU or land-use permit in unincorporated La Plata County³⁵. Ask Planning to confirm zoning approval for the proposed structure and occupancy, and remember that any OWTS construction, alteration or repair still needs a county septic permit⁹²⁹.

How do you build a home in La Plata County, step by step?

1. Confirm whether the parcel is unincorporated, then verify its zoning classification, district layers, setbacks and any Animas Valley rules with Planning⁴¹⁸.
2. For most unincorporated proposals, submit a feasibility evaluation with the parcel number, project description, access, water, OWTS and irrigation information, plus a site plan; Planning feasibility review generally takes about 2 weeks³⁶.
3. Secure proof of water supply and sewage disposal, using a Division of Water Resources well permit or district water tap and a county septic permit or sewer tap as applicable³⁷³³.
4. Obtain the county Engineering driveway permit, or a CDOT access permit for direct state-highway access²²¹¹.
5. For a new home in a floodplain hazard area, arrange pre- and post-construction elevation certificates; apply through CityView for the building permit and budget for building and applicable impact fees³⁸¹¹⁹.
6. Build to the approved plans and request each Building Division inspection at least one business day ahead²⁰.

What to check before you buy land in La Plata County

A new home supplied by a domestic well needs proof of a Colorado Division of Water Resources well permit; a district water tap can serve instead³⁷. For a new single-family home, confirm that the parcel can support proof of water supply and sewage disposal through permits or district taps³³. Ask for the septic inspection and continued-use paperwork because most septic-served properties require inspection before sale³². New-home applications for floodplain-hazard properties require pre- and post-construction elevation certificates³⁸. Confirm zoning, numeric setbacks and district overlays with Planning, because permit-exempt buildings still must meet applicable land-use and floodplain rules³⁹¹⁸. Confirm whether Engineering or CDOT controls the driveway permit²²¹¹.

Watch-outs

• Most La Plata County properties served by septic require an inspection before sale, subject to stated exemptions³².
• An Ag Plus land-use entitlement does not by itself qualify a structure for the county's agricultural building exemption, and changing an exempt building's use later requires a building permit and inspections¹⁶.
• We could not confirm an owner-builder exemption from La Plata County building permits for a new home; the state provision concerns contractor licensing for an owner’s repair or maintenance work, so ask the Building Division before relying on it⁶¹³.
• We could not confirm a private-land RV occupancy rule or a countywide minimum dwelling size; ask the Planning Division before choosing a structure or homesite⁹.

30. Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
