Ideas worth building on.

A legal second unit is a different project from a finished basement, and this category explains exactly where the line sits: the code requirements for an apartment in an existing house, what each build package costs, how fire separation and egress windows work, and an honest look at rental income against construction cost. The guides avoid two things on purpose — legal advice and rosy math — and stick to what the process looks like when our legal basement apartment team designs, permits, builds and registers a unit. If you are weighing the investment, start with the ROI guide; if you already have a basement apartment and want it legal, start with the requirements guide.
