No. 03— City code vs. HOA rights
Short-term rentals
Thornton municipal code
Thornton may license or zone short-term rentals under local ordinances in addition to Colorado Common Interest Ownership Act (CCIOA) & HB22-1137. Colorado does not preempt all municipal STR rules. Boards should obtain the current STR checklist from Thornton Planning or Excise & Licenses and compare it to recorded CC&R use restrictions. Enforce HOA rules only after confirming they do not conflict with a valid city license.
HOA governing documents
HOAs enforce recorded use restrictions (minimum lease terms, guest limits, parking) when consistent with applicable city licensure and state law. Covenant enforcement requires notice, cure periods, and uniform application.
Fences & structural additions
Zoning & building code
Thornton and Adams County zoning codes set baseline fence heights, setbacks, and sight triangles by district. HOAs may regulate design through architectural covenants if restrictions comply with CCIOA (C.R.S. title 38, article 33.3) and are applied consistently. Document both city zoning compliance and HOA ACC approval before approving fence or accessory projects.
Permit thresholds
When construction triggers the building code, Thornton or Adams County requires permits for structural changes, many electrical/plumbing alterations, decks, and additions. An HOA architectural approval letter does not substitute for a city building permit. Boards should require proof of city permit (or written exemption) before final ACC approval on regulated work.
HOA architectural control
HOAs review fences and additions through architectural committees under CC&Rs. Municipal compliance alone does not satisfy HOA design or notice requirements.
Solar & xeriscaping rights
State / local protections
C.R.S. §38-30-168 voids covenants that prohibit renewable energy devices (including solar). Aesthetic rules may not increase cost more than 10% or reduce production more than 10%, and approvals must follow statutory timelines. Water-efficient landscaping cannot be banned when it meets applicable water-district and municipal rules. HB22-1137 and CCIOA collection reforms also limit certain fee practices—confirm with association counsel.
What HOAs may still regulate
HOAs may adopt reasonable design rules that meet statutory tests (location, color, timeline). Associations cannot impose outright bans where state law voids them.

Neighborhood rules & collection
Municipal trash schedules, curb placement, and code enforcement pathways.
Municipal trash haulers or city collection programs set pickup days, cart rules, and bulky-item scheduling for Thornton. Property maintenance and nuisance codes are enforced by city/county code enforcement—not the HOA. Boards should route covenant violations through the association process and municipal issues (illegal dumping, abandoned vehicles on public streets) to the appropriate city department or 311 service.
Escalation & dispute resolution
Mediation, courts, and state resources when board actions are challenged.
Colorado disputes may be resolved through association internal processes, mediation, or state courts. Small claims jurisdiction is set by Colorado statute and court rule—verify current limits with the clerk of Adams County. The Colorado Department of Regulatory Agencies (DORA), Division of Real Estate, maintains HOA-related consumer resources. For collection disputes, comply with CCIOA notice and HB22-1137 cure requirements before referral to counsel.
