We remodel and update existing basements as well as construction of unfinished basements. Mother-in-laws and separate living spaces for vacation/rental income. Kitchens, bathrooms, living spaces, utility, storage, etc. Plumbing, HVAC ducting and electrical new installations or relocating.
A basement can also be an ADU (see link for more info), Mother-In-Law, treated as separate unit from the main house, so that you can use it to generate income. Cities have rules for ADUs, and we can check this for you.
