Turning single family into duplex

[David Hare]

Hi, My wife and I are thinking of turning our existing single family home into a two unit to rent out. Its a rancher and we want to turn the basement into a unit and the upstairs into another one. My question is, do i have to check into zoning with my state/county before we start? Are there any regulations that we need to consider before starting? Thanks for your guidance.

Absolutely MUST meet with zoning/permits/building department before you do anything else.  

IF they will permit such a use, the following items are fairly standard across the country:  2 means of egress, window sizing and number up to code, proper ventilation, heating.  Adequate ceiling height.  

If they will allow the change, you'll need to submit proper drawings and plans and obtain permits for plumbing, electrical, mechanical (heating), and any other permits as required by your jurisdiction (often required to be done by licensed/insured contractors).

Keep in mind you will need to change out your electric service panel to a 3-service entrance--1 meter for each apartment, 1 meter for 'common area'--exterior lights, etc.  The electric must be properly separated between the apartments so each apartment is only paying for it's own usage.  OR, you can leave the electric service alone and you will pay for/supply electricity for both units and common areas.

Same goes for water and hot water UNLESS you decide you will be paying for the water bill, sewer and hot water.

Then you must make sure you can get a c-o (certificate of occupancy) so you can legally have a 2-family dwelling.

Good luck!
