Home occupations are allowed in all residential zones in Mission Viejo subject to a home occupation permit and compliance with operating conditions. The business must be incidental to the residential use, conducted entirely indoors, and generate no external impacts. Certain business types that conflict with residential zoning are prohibited regardless of permit status.
Mission Viejo's zoning ordinance permits home occupations as an accessory use in all residential zoning districts, including single-family (R-1), planned residential development (PRD), and multi-family zones, subject to obtaining a home occupation permit. The home occupation must be clearly incidental and secondary to the residential use of the property. Zoning conditions for home occupations include: the business must be conducted entirely within the primary dwelling unit (not in a detached accessory structure, garage, or ADU); the use must not alter the exterior appearance of the dwelling or the residential character of the property; no outdoor storage, display, or activity related to the business is permitted; the business must not create noise, odors, vibrations, electromagnetic interference, or other impacts detectable at the property line; and the use must comply with all other applicable provisions of the zoning code including parking requirements. Businesses that are inherently incompatible with residential zones are prohibited, including but not limited to: vehicle repair or body work, welding or machining, commercial food preparation with a health department facility permit (cottage food exempt), medical or dental offices, massage therapy (unless a sole practitioner with proper licensing), beauty salons and barbershops, kennels or animal breeding, and warehousing or distribution. ADUs and Junior ADUs may not be used for home business activities under current Mission Viejo zoning standards.
Operating a prohibited business type in a residential zone may result in immediate cease-and-desist orders and administrative citations starting at $500. Operating without a home occupation permit carries citations starting at $250. Zoning violations may be referred to the City Attorney for legal action including injunctive relief.
