RenoBuzz designs and builds code-compliant legal basement apartments from start to finish.

The Return on Investment

$1,500–$2,500+/mo Rental income potential

Legal basement suites offer exceptional ROI. Beyond the monthly rental income, a legal suite can significantly increase your property value. Many of our clients see their renovation pay for itself within 2–4 years through rental income alone. With financing, your tenant's rent can often cover your renovation payments from day one.
