If you are building a new house, remodeling or renovating a home in Yucatan you are obligated to provide insurance for your construction workers.
If you hire an architect or contractor to do the job, responsibility of providing insurance rest on him and you as well.
Workers Compensation and Health Insurance is provided by the government run IMSS (Instituto Mexicano del Seguro Social), it contains two parts: The health insurance to the workers and their families, and INFONAVIT which provides subsidized housing for the workers.
Those two parts come as a package and you are obligated to pay for both.
The insurance has to be in effect from the moment you begin the work.
The insurance certificate has to indicate the property owners name and the address of the property, regardless of who obtained the certificate (owner, architect or a contractor).
The insurance prices are calculated by the IMSS and are based on type of construction, size of your job and the quality level.
IMSS - Workers Insurance cost, is a fraction of what you will have to pay in USA, Canada or Europe and is a must if you are attempting to build in Yucatan, and if you get caught without it, you will have to pay a large fine.
