Building Setbacks & Zoning in Redding, CA: What Residents Actually Need to Know

If you live in Redding or are thinking about moving there, building setbacks & zoning are one of those things you probably won't think about until they affect you directly. Redding has 3 specific rules on the books covering different aspects of building setbacks & zoning, and some of them might surprise you.

Setback Rules

Building setbacks in Redding are set by the Zoning Ordinance (Redding Municipal Code Title 18), with site-development regulations for the principal residential districts in RMC §18.31.030. The three primary residential districts are RE (Residential Estate), RS (Residential Single-Family), and RM (Residential Multiple-Family). Front, side, and rear yard minimums are listed in the development standards tables for each district. Variances and minor exceptions are handled under RMC Chapter 18.15.

Key details: Code: RMC Title 18 (Zoning); Ch. 18.31 (Residential Districts). Site Standards: RMC §18.31.030. Max Front Setback (RE/RS <40k sf): 50 ft or 40% of lot depth (greater). Side Yard with Dwelling Front: Min 15 ft. RM Abutting RE/RS (2nd story): Min 25 ft setback.

Building, expanding, or converting a structure within a required setback area without an approved variance or zoning exception is a Title 18 zoning violation. Redding Development Services will not issue a building permit or final certificate of occupancy for non-conforming work, and Code Enforcement (777 Cypress Avenue) can issue notices of violation and administrative citations with daily fines until corrected. Removal or modification of an encroaching structure is at the owner's cost.

Structure Height Limits

Building height limits in Redding are set by zoning district under Redding Municipal Code Title 18, with residential heights established in the development standards tables of RMC §18.31.030 and commercial / industrial heights in Chapters 18.32 and 18.33. Detached accessory structures generally must meet the same setbacks as the main building under §18.43.020, with adjusted setback rules for accessory structures 16 feet or less in height. Variances are processed under RMC Chapter 18.15.

Key details: Local Code: RMC Title 18 (Zoning). Residential Heights: RMC §18.31.030 (development standards tables). Accessory Structures: Same setbacks as main bldg (§18.43.020). 16-ft Threshold: Director discretion for accessory architectural fit. State Standard: California Building Code (RMC Title 16).

Building above the height limit set in the zoning district's development standards table is a Title 18 zoning violation: Development Services will not issue a building permit or certificate of occupancy until the structure is brought into compliance. Code Enforcement at 777 Cypress Avenue can issue notices of violation and administrative citations with daily fines. Building Code height violations under the California Building Code are enforceable separately with stop-work orders.

Lot Coverage Limits

Maximum lot coverage in Redding is set by zoning district under Redding Municipal Code Title 18, with residential coverage standards in the development tables of RMC §18.31.030. In the RM (Residential Multiple-Family) districts, lot coverage calculations explicitly include buildings, driveways, parking areas, and trash-enclosure areas — Schedule 18.31.030-D specifies the maximum allowable lot coverage in each RM district. Stormwater impacts on larger projects are reviewed under the City's MS4 program.

Key details: Code: RMC Title 18 (Zoning); §18.31.030. RM Coverage Includes: Buildings + driveways + parking + trash areas. Schedule: RMC Schedule 18.31.030-D (RM lot coverage). Stormwater: Phase II MS4 (State Water Board). ADU Protection: California Gov't Code §65852.2(j)(2).

Exceeding the maximum lot coverage in a district's development standards table is a Title 18 zoning violation: Development Services will not issue a building permit for new construction or additions exceeding the limit, and Code Enforcement (777 Cypress Avenue) can issue notices of violation and administrative citations for unpermitted construction. Stormwater non-compliance on larger projects can result in separate enforcement by the City and the State Water Board, including stop-work orders.

The Bottom Line

Redding's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Redding is broadly strict or permissive.
