Summary
Converting a Chico single-family garage or carport to living space means replacing the lost parking spaces, unless the conversion creates an accessory dwelling unit, per Chico Municipal Code Section 19.70.040.
Single-family homes shall retain or provide the required number of parking spaces when a garage or carport is converted to a use other than vehicle parking. However, when a garage, carport or covered parking structure is demolished in conjunction with the construction of an accessory dwelling unit, or is converted into an accessory dwelling unit, replacement of those off-street parking spaces shall not be required.

Full Breakdown
Chico Municipal Code Section 19.70.040(A) requires a single-family homeowner who converts a garage or carport to a use other than vehicle parking, a bedroom, office, or storage room, for example, to retain or replace the required number of off-street parking spaces elsewhere on the lot. The rule carves out a specific exception for accessory dwelling units: state ADU law (Government Code Sections 66310 through 66342) overrides conflicting local parking mandates, so Chico's own ordinance exempts any garage, carport, or covered parking structure that's demolished for, or converted into, an ADU from the replacement-parking requirement entirely.
Violations & Fines
Converting a garage without replacing the required parking is a zoning code violation caught at building-permit review; the city can withhold permit approval or require the replacement spaces be added to the site plan before work proceeds.
