Summary

Redwood City doesn't write its own rodent-control rules: Code section 13.1 adopts San Mateo County's Environmental Health Code Chapter 4.80, Rodent and Insect Control, by reference as the City's environmental health code, alongside the County's food, water and sewage-disposal chapters, enforced under the County's permit and fee system.

The Environmental Health Code of the County of San Mateo, as set forth in Chapter 4.52 Environmental Health Generally, Chapter 4.56 Food Facilities, Chapter 4.60 Fresh Water Sports Areas, Chapter 4.64 Water Supply System, Chapter 4.68 Wells, except for section 4.68.410 which is not adopted, Chapter 4.80 Rodent and Insect Control, Chapter 4.84 Individual Sewage Disposal Systems, Chapter 5.128 Alcohol Warning Signs, Chapter 5.52 Itinerant Restaurants, and Chapter 5.68 Food Establishments, of the San Mateo County Ordinance Code establishing health standards for restaurants, itinerant restaurants, mobile food vendors, caterers, food equipment, public fresh water sports areas, water supplies, wells, chemical toilets, rodent and insect control and alcohol warning signs, three (3) copies of which are on file with the City Clerk, are adopted by reference as the environmental health code for the City.

Full Breakdown

68 (Food Establishments). 2. 80 rather than in the city code itself, a property owner cited for a rodent or vector problem in Redwood City is actually being enforced against county health standards applied through this city-code adoption. 3 supplies the enforcement penalty for the whole chapter, including the rodent-control provisions.

Violations & Fines

Section 13.3 makes violating any provision of Chapter 13, including the adopted rodent and insect control standards, a misdemeanor punishable by a fine of up to $500, up to six months in county jail, or both. San Mateo County's Environmental Health Division, which the City relies on for enforcement, can also inspect properties and require abatement before a violation reaches that stage.

Frequently Asked Questions

Does Redwood City have its own rodent control ordinance?
No. Code section 13.1 adopts San Mateo County's Chapter 4.80, Rodent and Insect Control, by reference, so the county's standard, not a separate city rule, governs vector and rodent abatement inside Redwood City.
Who enforces rodent complaints in Redwood City?
The County's Department of Public Health and Welfare and its Environmental Health Division handle permits, fees and enforcement under the adopted county code, since Redwood City folded that chapter into its own code rather than staffing a separate rodent-control program.
What's the penalty for violating the rodent control rules?
Section 13.3 makes any violation of Chapter 13, including the adopted rodent and insect control standard, a misdemeanor: a fine of up to $500, up to six months in county jail, or both.
