How much does home addition cost in Aurora, CO?

Why is home addition more or less expensive in Aurora than elsewhere?

Aurora prices just under the Denver core. Severe hail seasons drive impact-rated roofing.

Do I need a permit for home addition in Aurora, Colorado?

City permits apply to most exterior and structural work. Always confirm current requirements with the local building department before signing a contract, and make sure the permit is pulled by your licensed contractor.

How many quotes should I get in Aurora?

Get at least three written quotes from licensed, insured Colorado contractors. Comparing line items — not just the bottom line — is the fastest way to spot an inflated bid in the Denver market.

How much does a home addition cost per square foot?

$150 to $450 per square foot. Garage conversions can be as low as $80; second stories and in-law suites reach $500.

Is an addition cheaper than moving?

Often yes, once you count agent commissions, closing costs, moving and a higher mortgage rate. Compare against local price per square foot before deciding.

How long does a home addition take?

Four to nine months including design and permitting. Construction alone is typically three to five months.

Do I need an architect?

For anything structural or over about 200 square feet, yes. Budget $3,000 to $15,000 for drawings and engineering.

Does an addition pay for itself?

Most additions return 50% to 70% of cost at resale. Master suites and in-law suites in high-demand markets do best.

What is the cheapest way to add space?

Finish existing square footage — a basement, attic or garage — at $80 to $200 per square foot rather than building new.

Ways to save in Aurora

Build up or bump out rather than adding a new foundation footprint.
Keep plumbing on the existing wet wall — moving water and waste lines is the costliest change.
Convert existing space (garage, attic, basement) at half the per-square-foot cost.
Keep the roofline simple; complex tie-ins add framing labor and leak risk.
Lock the design before demolition — change orders during construction carry the biggest premiums.
