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

City permits required for roofing and remodels. Always confirm current requirements with the local building department before signing a contract, and make sure the permit is pulled by your licensed contractor.

$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.

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

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?

Ways to save in Lakewood

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.
