Summary
Running an auto repair, maintenance or service business out of a Brentwood home is flatly illegal. Municipal Code § 17.840.007(G) lists "automotive repair, maintenance or other automotive services" among the uses "expressly prohibited as home occupations," with only a narrow carve-out for the resident's own personal vehicle.
The following uses shall be expressly prohibited as home occupations: ... ... G. Automotive repair, maintenance or other automotive services (except for the home occupant's personal vehicle);

Full Breakdown
007 opens "the following uses shall be expressly prohibited as home occupations" and then lists a full set of businesses that cannot operate from a Brentwood residence: medical, dental, chiropractic or massage offices; barber or beauty shops; pet grooming or boarding; walk-in retail or office uses where clients visit; TV, radio or appliance repair; cabinet-making, furniture manufacture or upholstery repair requiring power tools; automotive repair, maintenance or other automotive services except for the occupant's personal vehicle; storage of hazardous chemicals not normally found at a residence; bicycle, lawn mower or small-engine repair; and welding or paint spraying.
008, which caps home occupation equipment at motors of "more than a total of one horsepower," bars any commercial vehicle over one-ton capacity, and prohibits emission of odor or gaseous, liquid or solid waste, all of which are inherent to running an automotive shop.
Violations & Fines
Operating a prohibited use as a home occupation lets the community development director deny or revoke the underlying home occupation permit "after notice and an administrative hearing" under § 17.840.006(D). Because automotive repair is not an eligible use at all, a business license for that activity at a residential address would simply be denied; continuing to operate anyway exposes the operator to the code's general misdemeanor/infraction penalties under § 1.20.010, with each day of continued operation counted as a separate violation.
