Apartment renovation timelines are highly variable. On the short end, an apartment renovation from beginning to end could take 4 months; on the long end, it could take over a year. Obtaining permits from local municipalities, sourcing materials, and construction can add significant time to the renovation schedule. For example, some municipalities have very strict permitting processes, or may require specific plans to be submitted by an architect before permits are issued. If you’re sourcing luxury materials from sources abroad, shipping and importing the products can be lengthy. Also, discovering hidden surprises during demolition (think: water damage, or wiring issues) may require a contracting team to problem-solve before proceeding with construction as planned.
