Summary
Riverside building permits expire automatically if work isn't started within one year or stalls for a year without a real inspection showing progress, per RMC § 16.04.310. Demolition permits are stricter, voiding after 90 days. The Building Official can grant 180-day extensions or a one-time paid reactivation.
Except as otherwise specified, every permit issued by the building official under the provisions of Chapters 16.04 through 16.34 shall expire by limitation and become null and void if the work authorized by such permit is not commenced within one year from the date of permit issuance, or if the work authorized by such permit is suspended, abandoned, or without progress at any time after the work is commenced for a period of one year. For the purposes of this section, "progress" shall mean obtaining one or more successful inspections that demonstrate completion of work representing advancement to the next sequential stage of construction in accordance with the approved plans and Section 110 of the California Building Code... Prior to a permit's expiration and upon a showing of justifiable cause by the permit holder or property owner in writing, the Building Official may issue one or more extensions for periods not to exceed 180 calendar days. A permit for demolition, however, shall expire by limitation and become null and void if the work authorized by the permit is not completed within 90 days from the date of permit issuance.

Full Breakdown
020. 34 becomes null and void if work doesn't commence within one year of issuance, or if it stalls for a year after starting. The code defines "progress" narrowly: it means a successful inspection showing real advancement to the next construction stage under the approved plans and CBC Section 110, scheduling an inspection just to keep a permit alive doesn't count. The Building Official may grant one or more extensions of up to 180 calendar days each upon a written showing of justifiable cause. Demolition permits are on a tighter clock, voiding after just 90 days if the work isn't finished.
A lapsed permit can be reactivated once the applicant shows circumstances beyond their control caused the delay and pays a reactivation fee equal to half the cost of a new permit, provided the plans haven't changed and the code cycle hasn't turned over; after that, a full new permit and full fee are required. 335: an application expires 365 days after submittal if no permit issues, can be extended in 180-day increments upon justifiable cause, and can never run past 720 days from the original submittal.
040 lets the Building Official withhold a permit where existing on-site code violations, including zoning violations, remain unresolved, or where site hazards make the work unsafe to perform. 372.
Violations & Fines
Starting work before a permit issues, or continuing after one has expired, exposes the property owner to a permit investigation fee under § 16.04.374 equal to the cost of the permit itself, charged before the City will even issue it, and paying that fee doesn't excuse the owner from any other penalty the Code allows. Beyond that, Riverside's general administrative and criminal enforcement provisions (§§ 16.04.510–.540) apply, including administrative citations, civil penalties, and summary abatement for unsafe or noncompliant work. Owners can appeal Building Official decisions, including permit denials and expiration determinations, to the Board of Building Appeals under § 16.04.470.
