Summary
Any interior work permit in Rialto valued over $1,000 triggers a mandatory smoke detector upgrade to current California Building Code standards. Section 15.04.010 of the Municipal Code ties life-safety compliance to the building permit process rather than a standalone inspection program, and the same permits require GFCI-compliant electrical outlet upgrades wherever new or altered electrical service is involved.
Unless waived by resolution of the city council, the issuance of any permit for interior work, when the total value of said alteration exceeds one thousand dollars, the following shall be required within the scope of work:1.Smoke detectors shall be upgraded to meet current California Building Code requirements.C.Every owner, lessee, occupant, or person having charge of any property or premises within the city who maintains a violation of this title after given notice stating a reasonable time period for compliance, as determined by the building official or fire chief, is subject to prosecution as provided in Chapter 1.16 of this code.

Full Breakdown
010, adopted under Ordinance 1414 in 2008 and administered by the building and safety division, sets a dollar threshold that pulls older homes into current life-safety compliance whenever a resident pulls a permit. Subsection A requires any new electrical service, service upgrade, alteration or restoration to bring electrical outlets in the building up to the current California Electrical Code's ground-fault circuit interrupter requirements. Subsection B applies specifically to permits for interior work: once the total value of the alteration exceeds $1,000, and unless the city council waives the requirement by resolution, the scope of work must include upgrading smoke detectors to meet current California Building Code requirements, even if the interior work itself has nothing to do with fire alarms.
015 carves out one exemption: improvements made solely to comply with a separate federal, state or local mandate are not counted toward the $1,000 threshold, so a homeowner completing a mandated repair alone will not automatically trigger the smoke detector upgrade. 16 of the Municipal Code, the city's general penalty chapter. Because the trigger is the permit's total value rather than the age of the smoke detectors themselves, a $1,200 kitchen remodel can require a whole-house smoke detector upgrade even though the original alarms may still be working.
Violations & Fines
Pulling an interior work permit valued over $1,000 without upgrading smoke detectors to current California Building Code standards violates Section 15.04.010(B). The building official or fire chief can issue a notice setting a reasonable compliance deadline, and an owner, lessee or occupant who maintains the violation past that deadline is subject to prosecution under Chapter 1.16, Rialto's general penalty provision, in addition to permit or occupancy consequences.
