"Jose and his crew do fantastic work. Did all work as promised and on budget. Only change orders were on our side adding things. Alta was originally hired to replace total roof. Work was completed in 2 days with all trash removed. Our replaced bathroom is now the star of the house! We have hard wood floors and new work matched flooring with no noticeable change. Our last project just completed was a sunroom and shed with partition pavers creating a great sitting area. Everything Alta did was done well and we are so very happy. This is the only company I will use from now on. All of his employees and subs were pleasant, answered any questions we had and very professional."

FAQs for garage remodeling projects in Islip, NY

A garage apartment represents a valuable addition to your property when properly constructed according to local regulations. The potential benefits include additional living space for family members, rental income possibilities, and increased property value. 

Your specific return depends on local housing market conditions, construction quality, and ongoing maintenance. Consider consulting with a real estate professional regarding potential returns in your neighborhood.

Building a garage apartment requires multiple permits, with basic residential garage permits starting at $74 in most locations. You'll need separate approvals for structural elements, electrical systems, plumbing installations, and mechanical components. 

Many jurisdictions also require specific approval for accessory dwelling units. Contact your local building department early in your planning process to understand all requirements and associated costs.

Converting an existing garage into living space presents an alternative to new construction. The feasibility depends on your garage's structural condition, foundation type, and local zoning regulations. Key considerations include insulation requirements, utility connections, and moisture control. Research local codes thoroughly, as many municipalities have specific requirements for garage conversions.
