Full Breakdown
The UDC allows a 'home occupation', business activity conducted entirely inside a dwelling or garage by its residents, as an accessory use in districts R-1, R-2, R-MF, R-MH, M-OF, M-N, M-C, M-DT, M-BP, and A per Table 29-3.1. No non-resident employees may work on-site, and the business can't use more than 20% of the dwelling and garage floor area, alter the home's residential appearance, or add a dedicated commercial entrance. Adding one full-time or two part-time non-resident employees reclassifies the use as 'home occupation with non-resident employees,' which needs a conditional use permit valid for three years.
Violations & Fines
Exceeding the 20% floor-area cap, altering the home's exterior for the business, or hiring help without the required conditional use permit is a zoning violation under UDC § 29-6.6, a misdemeanor fined $10-$250 per day.
