What to know about remodeling a basement in Aurora
One city, three counties
Aurora crosses Arapahoe, Adams and Douglas counties. Homes inside city limits still get their permit from the City of Aurora. The county line only matters for addresses outside the city.
Bare basements in newer homes
Plenty of newer Aurora homes come with an unfinished basement. A first-time finish starts from bare concrete and open joists. The contractor checks the slab, the walls and the ceiling height at the estimate.
The Denver contractor covers Aurora
The contractor that serves metro Denver takes jobs across Aurora. Centennial and Parker sit on the same route. Only that one contractor contacts you about your basement.

Finishing an Aurora basement under the city's current codes
Do I need a permit to finish my basement in Aurora?
Yes, finishing a basement in Aurora needs a building permit from the City of Aurora Building Division. The division issues permits for homes inside city limits in Arapahoe, Adams and Douglas counties. Its offices are at 15151 E. Alameda Parkway.
The Building Permit Center within the division answers permit questions, tracks plan review and takes inspection requests. Applications go through the city's Aurora4Biz online portal. Your contractor sets up the application, uploads the plans and answers the plan reviewer if the city asks for changes.
A number of addresses that say Aurora on the envelope sit outside city limits. Those file with their county building office. The Building Division pages link to a city property information lookup you can use to check.
Which electrical code applies to an Aurora basement in 2026?
The 2026 National Electrical Code applies to new electrical permit applications in Aurora. The city moved to it together with the State of Colorado, effective August 1, 2026. Every new electrical application is reviewed and inspected to that edition.
A basement finish adds circuits, outlets, lights and often a bathroom fan. The contractor draws the electrical plan to the current edition. If you got a quote before August 2026, ask whether the electrical scope still matches. Have the code edition noted on the quote so everyone works to the same rules.
How long does it take to finish a basement in Aurora?
The time depends on basement size, the rooms you add and how fast each inspection passes. A plain open finish moves faster than one with a bathroom and a bar. Weather rarely slows a basement job, since the work is indoors. Digging for a new egress window is the exception.
Plan review time is set by the city, so treat that stage as a range. Your contractor gives you a written schedule with the quote. Most jobs follow the same order:
Plans drawn and permit approved
Framing and any new window openings
Rough electrical, plumbing and ductwork
Rough inspections before walls close
Insulation, drywall and paint
Flooring, trim, fixtures and the final inspection
Can I finish my own basement in Aurora?
Aurora publishes a DIY and DIR home improvement brochure for homeowners planning their own projects. Read it before you decide to take the work on yourself.
Hiring out still means checking the contractor. The Building Division runs contractor licensing and keeps a contractor lookup online. Search the name on your quote before you sign.
Your matched contractor pulls the permit and books each inspection. You approve the plan and the price before any work starts. Keep a copy of the approved plans on site for the inspector.
