Summary
Santa Ana requires smoke detectors 'installed throughout the live/work spaces' of any converted artist live/work building in a C3A zone, under Municipal Code § 8-2701(i), which ties the mandate to California Building Code § 310.9. The rule sits inside a broader alternative fire and life-safety code the city built for adaptive reuse of existing structures.
(i)Smoke detectors. Smoke detectors shall be installed throughout the live/work spaces in accordance with California Building Code section 310.9. (a)Exits.(1)The occupant load of a live/work space shall be based upon one (1) occupant per three hundred (300) square feet. Two (2) exits shall be required from each space when the occupant load exceeds ten (10) people.(2)Each live/work space above the second floor shall have access to two (2) stairway exits. An existing fire escape may be used as one (1) of the required exits, provided it complies with California Building Code Appendix Chapter 34. An operational test performed by the fire department is required prior to occupancy by any tenant.

Full Breakdown
11. 1, without a required separation between the living and working portions. Section 8-2701 lays out the alternative fire and life-safety standards that come with that classification: occupant load is calculated at one person per 300 square feet, and any space with a load over ten people needs two exits; spaces above the second floor need access to two stairway exits (an existing fire escape can serve as one, if it meets CBC Appendix Chapter 34 and passes a fire department operational test before any tenant occupies the space); mezzanines over 2,000 square feet also need two exits.
' Section 8-2700(5) separately bars hazardous activity, welding, open flame, or storage of flammable liquids, inside a live/work space without specific written sign-off from both the fire department and the building official.
Violations & Fines
Chapter 8's general violation scheme in § 8-7 governs live/work noncompliance: any violation is punishable as provided in § 1-8 of the Municipal Code, with each day a missing or non-functioning smoke detector, or any other alternative-standard violation, treated as a separate offense. A live/work unit found without required detectors, blocked exits, or unapproved hazardous activity can also have its occupancy approval revoked or its certificate of occupancy suspended, since § 8-7(d) lets the administrative authority revoke a permit, approval, or certificate of occupancy issued in error or maintained in violation of the chapter.
