Reno Mumu
A Home Addition Renovation Begins with Due Diligence
A custom home addition changes more than interior finishes. Zoning, structure, mechanical systems, building permits, site access, and temporary protection may all affect feasibility.
Reno Mumu coordinates the contracted renovation work and applicable permit process. Architects, engineers, surveyors, government charges, and other third-party services are separate unless expressly included.
