Home estimates in and of themselves take time and effort, so expect the conception of your home's addition to cost money before even a single nail is hammered. Costs such as highering a designer or engineer. Other unseen costs could be a minor variance, zoning change, lawyer fees, building permit fees, accessory dwelling fees, demolition fees to remove an old addition to make way for the new, septic permit to increase the size, or even new taxation just to name a few.
FACTORS AFFECTING THE COST OF AN ADDITION
A common question that homeowners ask is how much a new addition will really cost after an estimate is provided. There is often wide variance. The answer, however, is more elusive, as adding on to any home — whether it is building out from the pre- existing footprint or adding a new level on top of it — is subject to a host of complex factors.
These factors may include (when applicable):
• Architectural design • Site preparation (demolition, excavation) • Concrete work • Support structure (standalone and/or in conjunction with existing structures) • Roofing materials • Siding • Ceilings/Walls
• Carpentry • Inspections • Electrical and Lighting • Plumbing • HVAC • Carpeting
