Quick Answers About Durango, CO ADUs
Market Context
Durango has a median home value of $680,000. Adding an ADU typically increases that by 23% — approximately $156,400 in added equity. A 1-bedroom ADU in Durango rents for approximately $2,800/month in the La Plata County rental market , yielding a 5.8% cap rate on the investment. Occupancy averages 96% in this market.
Top Durango neighborhoods for ADU investment include Downtown / The Grid (SoCo), Hillcrest, Skyridge (SkyRidge), Three Springs, Dalton Ranch. Highest rental demand and proximity to downtown jobs and amenities make in-town lots prime for ADUs. Large single-family lots, close to Fort Lewis College and elevated views—good lot sizes and owner-occupancy stability.
Permit Process
Permit applications are reviewed by the Community Development Department , with a plan check timeline of approximately 6 weeks. Permit fees in Durango range from $800 to $5,000 depending on project scope. Design review: Yes - citywide (Limited Use Permit required); additional Historic Preservation Board review may apply in historic districts
While ADUs have been legal in Durango since 2014, recent code amendments in 2022 and council votes in early 2026 have reduced restrictions, including eliminating minimum parcel size requirements for detached ADUs. However, owner occupancy is still required for either the principal residence or the ADU, and only one unit can be rented by a non-owner.
"In my experience with Durango submittals, that $450/sqft figure and 6-week timeline read like state-level estimates rather than local reality, so I'd call the Community Development Department directly and get a couple of local contractor quotes before you budget or schedule around them. I've also seen even straightforward drawing sets take longer than 6 weeks once a round of corrections comes back, so build in a buffer rather than planning around the best-case number."
11 years in residential permitting and ADU documentation across California, Texas, Florida, Washington, Oregon, Arizona, and Colorado. This guide was researched and verified against Durango's building department records and current 2026 Colorado's HB24-1152 ADU law.
Property Eligibility
Is My Durango, CO Property Eligible for an ADU?
Durango homeowners are governed by Colorado's HB24-1152 (2024). Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Durango under Colorado's HB24-1152 (2024). Durango requires owner occupancy — the property owner must reside in the primary home or the ADU. Colorado doesn't set a fixed statutory review-day count — confirm the current timeline with the Community Development Department.
Multi-Family Property
Additional ADUs on multi-family and duplex lots may qualify under Colorado's HB24-1152 (2024) — the exact number and type allowed depends on Durango's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 35% of Durango homes are in an HOA. Colorado's C.R.S. §38-33.3-106.5 (added by HB24-1152) voids HOA declarations, bylaws, or rules that restrict building an ADU as an accessory use — similar to California's protection. HOAs can still apply reasonable design standards. Our drawings include HOA submission formatting.
Historic Districts
Yes - citywide (Limited Use Permit required); additional Historic Preservation Board review may apply in historic districts
Always verify eligibility with Community Development Department before designing.

Durango ADU Return Calculator — Built With 2026 Local Data
Pre-loaded with verified Durango construction costs, median rental rates, and property value uplift data. Adjust the inputs to model your specific project.
Your Project
Projected Returns
* Estimates only. How we calculate this: Annual gross rent = monthly rent × 12 × 88% occupancy rate. Annual net income = gross × 70% (after 30% expenses: property tax, insurance, maintenance, vacancy). Value added = median home value × 23% uplift (regional ADU comparables). Total return = net income × years + value added. Break-even = total build cost ÷ annual net income. Consult a licensed financial advisor before investing.
Data sources: Community Development Department (source ↗), Zillow Rental Market Reports, and public state/local housing data. Last verified: 2026-07-12.

Durango ADU Market at a Glance
Local Zoning Rules
2026 Durango ADU Rules
Durango's 2026 ADU ordinance caps new units at 550 sq ft and 20 ft of height — restrictive, which rules out most 2-bedroom layouts. Setbacks run tight — 3 ft side / 3 ft rear — which leaves more of the lot buildable. Durango doesn't trigger the extra engineer-stamp requirement we see in higher seismic-risk or hurricane-code cities — a standard code-compliant ADU under the size cap can typically be designed and submitted without an architect or engineer stamp, though any load-bearing change to the existing house still needs one.
Permit fees run $800–$5,000 — in line with what most homeowners budget for permitting, and plan check takes about 6 weeks at Community Development Department. Submit directly to the department online — link below.
| Regulation | Durango Allowance |
|---|---|
| Max ADU Size | 550 sq ft |
| Max Height | 20 ft |
| Side Setback | 3 ft |
| Rear Setback | 3 ft |
| Architect / Engineer Stamp | Not required under the size cap* |
| Owner Occupancy | Required |
| Short-Term Rental | Restricted |
| Coastal Overlay | No |
| Design Review | Yes - citywide (Limited Use Permit required); additional Historic Preservation Board review may apply in historic districts |
| HOA Prevalence | 35% of properties |
| Permit Fees | $800–$5,000 |
*Load-bearing modifications to the existing house always need an engineer stamp regardless of ADU size. Data verified 2026-07-12T23:00:00.000Z. Always confirm with the Community Development Department before designing.
