Quick Answers About Greeley, CO ADUs
Market Context
Greeley has a median home value of $330,000. Adding an ADU typically increases that by 23% — approximately $75,900 in added equity. A 1-bedroom ADU in Greeley rents for approximately $999/month in the Weld County rental market , yielding a 6.6% cap rate on the investment. Occupancy averages 88% in this market.
Top Greeley neighborhoods for ADU investment include Glenmere / Cranford, Arlington Park, Alta Vista, Downtown Greeley, Kelly Farm. Close to the University of Northern Colorado with many older single‑family homes and sizable yards ideal for ADUs. Directly adjacent to UNC and composed largely of single‑family homes that attract student and faculty rental demand.
Permit Process
Permit applications are reviewed by the Community Development , with a plan check timeline of approximately 6 weeks. Permit fees in Greeley range from $13,924 to $16,612 depending on project scope. Design review: Yes - in historic districts only
Greeley's Community Development department requires a separate sewer tap fee study for most ADUs, since the city's aging clay pipe infrastructure in older neighborhoods like the Jefferson or Glenmere districts sometimes can't handle added capacity without a line assessment — this can add several weeks before your permit even gets scheduled for review. Weld County also layers on its own septic or well verification if your lot predates certain municipal water annexations, which catches a lot of homeowners off guard mid-process. Because Greeley allows short-term rentals, you'll also need to budget time for a separate STR license application through the city after your certificate of occupancy, since that approval doesn't move in parallel with your building permit.
"In my experience with Greeley homeowners, that 6-week plan check figure is optimistic — it's really a state-level estimate, and incomplete drawing sets (which is most first submittals) will push you closer to 10-12 weeks in practice, so call Community Development directly before locking in a start date. The $200/sqft cost is also a broad estimate rather than a Greeley-specific number, so I'd get at least two local contractor quotes before you build your budget around it."
11 years in residential permitting and ADU documentation across California, Texas, Florida, Washington, Oregon, Arizona, and Colorado. This guide was researched and verified against Greeley's building department records and current 2026 Colorado's HB24-1152 ADU law.
Property Eligibility
Is My Greeley, CO Property Eligible for an ADU?
Greeley 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 Greeley under Colorado's HB24-1152 (2024). No owner-occupancy requirement in Greeley — you can rent both units as investment properties. Colorado doesn't set a fixed statutory review-day count — confirm the current timeline with the Community Development.
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 Greeley's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 25% of Greeley 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 - in historic districts only
Always verify eligibility with Community Development before designing.

Greeley ADU Return Calculator — Built With 2026 Local Data
Pre-loaded with verified Greeley 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.

Local Zoning Rules
2026 Greeley ADU Rules
Greeley's 2026 ADU ordinance caps new units at 1,200 sq ft and 25 ft of height — in the typical range most ADU floor plans are designed around. Setbacks run 5 ft side and 5 ft rear, close to the regional baseline. Greeley 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 $13,924–$16,612 — among the higher permit costs we track, and plan check takes about 6 weeks at Community Development. Submit directly to the department online — link below.
| Regulation | Greeley Allowance |
|---|---|
| Max ADU Size | 1,200 sq ft |
| Max Height | 25 ft |
| Side Setback | 5 ft |
| Rear Setback | 5 ft |
| Architect / Engineer Stamp | Not required under the size cap* |
| Owner Occupancy | Not required |
| Short-Term Rental | Permitted |
| Coastal Overlay | No |
| Design Review | Yes - in historic districts only |
| HOA Prevalence | 25% of properties |
| Permit Fees | $13,924–$16,612 |
*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 before designing.
