Before You Build in Chino, CA: Permit & Rule Checklist (2026)

Chino Municipal Code Title 20 (Zoning) regulates fence heights through CMC § 20.10.080 (Walls and Fences). Typical residential standards allow 6 ft in side/rear yards and 42 in (3.5 ft) in required front yards, with corner-lot visibility triangles required at intersections.

California Civil Code § 841 (the 'Good Neighbor Fence Law') presumes adjoining owners share equally in the cost of construction, maintenance, and replacement of a boundary fence. A 30-day written notice is required before incurring shared costs. Chino has no separate local cost-sharing rule.

Per CBC § 105.2 (as adopted in CMC Title 15), retaining walls 4 ft or less in height (measured from bottom of footing to top of wall) and not supporting a surcharge are exempt from building permit. Taller walls or surcharge-loaded walls require permits, plans stamped by a licensed engineer, and inspections.

Chino Municipal Code § 20.10.080 (Walls and Fences) regulates fencing materials. Wood, masonry, wrought iron, vinyl, and tubular steel are standard. Barbed wire, razor wire, and electrified fences are prohibited in residential zones consistent with San Bernardino County practice.

Chino enforces California's Swimming Pool Safety Act (Health & Safety Code §§ 115920–115929, SB 442) requiring at least TWO of seven drowning-prevention features for any new or remodeled pool/spa at a single-family home. Enclosure barriers must be 60 in minimum, with ≤ 2 in ground clearance and no 4-in sphere passage.

Chino enforces the California Swimming Pool Safety Act (Cal. Health & Safety Code §115923) at building-permit issuance. Pool enclosures must be at least 60 inches high with no more than 2 inches of ground clearance, gates self-closing and self-latching with the latch at least 60 inches above the ground.

Chino requires a building permit for any swimming pool, spa, or hot tub deeper than 18 inches under the California Building Code adopted in Chino Municipal Code Title 15 (Buildings and Construction). Permit review covers structural plans, electrical bonding (CEC Art. 680), gas/plumbing, and barrier compliance with state pool safety law.

When Chino issues a permit for a new pool or remodel, the pool must include at least TWO of seven drowning-prevention features under Cal. Health & Safety Code §115922 (SB 442, 2018). Options include a code-compliant enclosure, ASTM F2286 mesh fence, ASTM F1346-23 safety cover, exit alarms, self-closing door device, ASTM F2208 water-entry alarm, or equivalent approved protection.

Above-ground pools deeper than 18 inches are treated as 'swimming pools' under Cal. Health & Safety Code §115921 — Chino requires a building permit, SB 442 barrier features, and CEC Article 680 electrical bonding even for inflatable or portable units. Zoning setbacks in residential zones apply under Chino Municipal Code Title 20.

Hot tubs and portable spas holding water deeper than 18 inches are 'swimming pools' under Cal. Health & Safety Code §115921 and trigger Chino building permits, SB 442 features, and CEC Article 680 electrical bonding. A locking cover meeting ASTM F1346-23 is the most common compliance choice for portable spas.

Chino regulates Accessory Dwelling Units (ADUs) and Junior ADUs (JADUs) under Chino Municipal Code Chapter 20.11 (Accessory Structures), implementing California Gov. Code §65852.2 and §65852.22. One ADU and one JADU are allowed per single-family lot; JADUs must be entirely within the existing single-family residence footprint or attached garage and capped at 500 sq ft. State law preempts the city on ministerial approval, size minimums, and parking exemptions within 1/2 mile of transit.

California Gov. Code §65852.2 (now re-codified by SB 477 at Gov. Code §66310 et seq.) preempts local bans on converting an existing garage into an Accessory Dwelling Unit. Chino adopted a conforming ADU ordinance on March 17, 2020 (Chino Municipal Code Title 20). Garage-to-ADU conversions are permitted ministerially, replacement parking is NOT required when a garage is converted to an ADU, and approval must be issued within 60 days of a complete application.

Chino regulates sheds and detached accessory buildings under Title 20 (Zoning). Small sheds 120 sq ft or less are exempt from building permits under the California Residential Code (CRC Section R105.2 / CBC Appendix M as adopted in Chino Municipal Code Title 15), but zoning setbacks, height limits, and lot-coverage rules in Title 20 still apply. Sheds may not be placed in a required front yard, and equestrian-zone parcels in the Chino Agricultural Preserve have separate barn/stable provisions.

Carports in Chino are regulated as accessory structures under Chino Municipal Code Title 20 (Zoning) and require a building permit under Title 15 (which adopts the California Building Code and California Residential Code). Detached carports must meet residential-zone setbacks (typically 5 ft side / 5 ft rear in R-1) and height limits, and attached carports must meet the principal-dwelling setbacks. Replacing a garage with a carport does not eliminate required covered parking unless the conversion is to an ADU (then state law exempts replacement parking).

Chino allows tiny homes only through three regulated pathways: (1) a permitted Accessory Dwelling Unit (ADU) up to 1,200 sq ft on a permanent foundation under Gov. Code §65852.2 (now §66310 et seq.) and Chino's 3-17-20 ADU ordinance; (2) a Junior ADU (JADU) up to 500 sq ft within an existing single-family dwelling under Gov. Code §65852.22 (now §66333 et seq.); or (3) a Movable Tiny House registered as a recreational vehicle / park trailer under Cal. Health & Safety Code §18010 and ANSI A119.5 — but only as a temporary RV, not a permanent residence on a single-family lot.

Chino Valley Fire Protection District enforces the California Fire Code (CFC) as adopted under CVFD Ordinance 2022-01 and amended by Ordinance 2025-01 (effective Sept. 1, 2025). CFC Section 307.4.2 limits recreational fires to a pile no larger than 3 ft in diameter and 2 ft in height, set back at least 25 ft from any structure or combustible material. Portable outdoor fireplaces must be at least 15 ft from structures. South Coast AQMD Rule 444 also limits open burning, and SCAQMD seasonal No-Burn Days (Rule 445) restrict wood-burning in the South Coast basin, which includes Chino.

Chino sits within the South Coast Air Quality Management District (SCAQMD) basin, where SCAQMD Rule 444 prohibits virtually all open outdoor burning. Burning rubbish, leaves, yard waste, construction debris, or land-clearing material is banned year-round. Only narrow exemptions exist: code-compliant recreational fires (CFC §307.4.2), agricultural burning by special permit, prescribed fire by CVFD, and gas-fueled appliances. CVFD must issue an open-burning permit under CFC §105.6.30 for any allowed open burn.

Street trees and parkway trees in Chino are regulated under Title 11 (Streets, Sidewalks and Public Places) and Title 12 (Public Property). Property owners are responsible for trimming private trees that overhang the public right-of-way to maintain mandated clearance (typically 8 feet over sidewalks and 14 feet over roadways). Removal or major pruning of designated street trees requires a city permit and follows ISA pruning standards. State law (Public Utilities Code section 12808) and CPUC General Order 95 govern clearance around overhead utility lines.

Chino is served by the city water utility within the Inland Empire Utilities Agency (IEUA) wholesale service area and the adjudicated Chino Basin Watermaster. State regulations adopted by the State Water Resources Control Board prohibit specific outdoor water-waste practices statewide (runoff onto sidewalks, hosing down hardscape, non-recirculating fountains, irrigating within 48 hours of measurable rain). Chino additionally enforces day-of-week and time-of-day watering restrictions through its water utility under Title 13 (Public Services).
