Whenever a new owner closes the deal on a city apartment, they generally have plans to update it. City building codes, like those in any area of the world, are strict. It is wise to hire a seasoned contractor to do the work, and a good architect is usually worth their fee. Making small changes can be quick and easy, but major changes require hiring people with the knowledge to do the job correctly. Those who skimp on this step will find they must live with their error, and it could make reselling their apartment almost impossible.
Unlike resident buildings in other areas, there are nearby neighbours to consider when it comes to remodelling an apartment. Most cities have established hours when contractors can work, and their code department will ticket violators. Experienced contractors know the rules, and they are used to manoeuvring materials through older city buildings. Residents who prefer to do their own work will find that only the smallest jobs are easy to do on their own.
