Home businesses in Martinez are allowed in residential zones (R-1, R-2, R-3 and similar) through a Home Occupation Permit, provided they meet performance standards preserving residential character. Certain uses — retail, manufacturing, vehicle repair, and high-traffic operations — are prohibited regardless of compliance.
Martinez Home Occupation Permits prohibit non-resident employees from working on-site. Only individuals who reside in the home may conduct the business there. Off-site or remote employees are allowed. Exceptions exist for family daycare and limited state-protected uses.
Martinez prohibits exterior signage advertising home-based businesses in residential zones. The Zoning Ordinance's home occupation standards are explicit that the business must not be visible from the public right-of-way, which includes no window signs, yard signs, banners, or exterior lighting that identifies the business. This rule preserves residential neighborhood aesthetics and is strictly enforced.
Martinez limits short-term rental occupancy based on bedroom count and building code standards. The general rule is 2 occupants per bedroom plus 2 additional, with a hard cap tied to fire and life-safety code. Operators must post occupancy limits inside the rental and include them in platform listings.
Martinez requires short-term rental (STR) operators to register with the City, obtain a business license, and remit Transient Occupancy Tax at 10 percent. An STR is any rental of a residential dwelling for 30 days or less. Registration requires proof of ownership or landlord authorization, a local contact, and compliance with safety and parking standards.
Martinez does not publish a separate STR-specific noise standard. Any short-term lodging activity in the city must comply with the citywide Noise Control ordinance in Martinez Municipal Code Chapter 8.34, the general nuisance provisions in Title 1, and any conditions imposed through the bed-and-breakfast / lodging framework cross-referenced from MMC Section 22.04.051. Persistent noise disturbances at a guest-occupied dwelling can be cited as a public nuisance and can also support enforcement against any underlying use permit.
Martinez has not adopted a short-term rental ordinance and does not impose an STR-specific off-street parking ratio. Any rental dwelling must satisfy the off-street parking requirements that already apply to its underlying residential use under the Martinez Zoning Code (Title 22), and on-street parking by guests is subject to the citywide rules in Title 10 of the Municipal Code, including the 72-hour vehicle-storage limit under California Vehicle Code Section 22651(k).
Martinez has not adopted a short-term rental ordinance, and the city does not impose a minimum liability-insurance requirement on short-term lodging operators. California has no statewide STR insurance mandate either - insurance minimums are set by each city or county that has adopted an STR program, and Martinez has not done so. Hosts are nonetheless strongly advised to carry commercial-grade liability and property coverage, because standard homeowner's policies typically exclude paid short-term lodging activity.
Short-term rentals (stays under 30 days) are NOT permitted within the City of Martinez. The city's zoning code does not include a regulatory framework for STRs, and operating an Airbnb, VRBO, or similar platform rental is prohibited. Long-term rentals (30+ days) are permitted.
Because short-term rentals are prohibited in Martinez, there is no local Transient Occupancy Tax (TOT) framework for STR operators. Illegal STR operators remain subject to California state tax liability. No TOT applies to compliant 30+ day rentals.
Livestock (horses, cattle, goats, sheep, pigs) is prohibited on standard residential lots in Martinez and restricted to parcels with agricultural zoning or minimum lot sizes typically over one acre. Miniature goats and potbellied pigs may be allowed as pets with setback requirements on larger lots. Rural parcels in unincorporated Contra Costa County near Martinez follow less restrictive county standards.
Wildlife in Martinez is protected under California Department of Fish and Wildlife regulations — feeding deer, coyotes, raccoons, turkeys, and other wildlife is prohibited and can result in fines. Injured wildlife should be reported to CDFW or Lindsay Wildlife Experience. The John Muir historic buffer and Alhambra Creek corridor host protected species requiring special consideration for landscaping and development.
Martinez follows California Food & Agricultural Code §31683, which preempts breed-specific legislation — dangerous dog designation is based on behavior only. Dogs that bite or threaten people or other animals may be declared dangerous or vicious through a hearing process, with requirements including muzzling, secure enclosures, liability insurance, and signage. Vicious dog designations can result in destruction orders.
All dogs in Martinez must be on a leash of six feet or less when off the owner's property, except in designated off-leash areas. The city's primary off-leash dog park is at Rankin Park. Violations result in fines starting at $50 for first offenses and $100-$250 for repeat violations, enforced by Contra Costa County Animal Services.
Martinez limits residential properties to a maximum of three dogs and three cats over four months of age per single-family dwelling. Kennels, catteries, or properties exceeding these limits require a special use permit from the Community Development Department.

Martinez allows up to six hens on residential lots in most single-family zones, with no roosters permitted. Coops must be set back at least 10 feet from property lines and 25 feet from neighboring dwellings, maintained in sanitary condition, and provide adequate shelter. Slaughter on residential properties is prohibited. No permit is required for compliant small-flock keeping.
Beekeeping is permitted on residential properties in Martinez with setback requirements — hives must be at least 10 feet from property lines and 25 feet from neighboring dwellings, or behind a six-foot flyway barrier. Registration with the Contra Costa County Agricultural Commissioner is required for all beekeepers. Hive numbers are limited based on lot size, typically two hives per 5,000 square feet.
Exotic animals are regulated under California Fish & Game Code and CA Code of Regulations §671. Ferrets and hedgehogs are illegal statewide. Other exotic species require a CDFW permit. Contra Costa County Animal Services enforces locally.
Martinez does not impose a blanket overnight street parking ban, but vehicles cannot remain parked longer than 72 consecutive hours under CVC 22651(k). Oversized vehicles, RVs, and trailers face additional restrictions. Some residential permit districts limit overnight non-permit parking.

Annual inspections may be conducted by Contra Costa County Fire Protection District.

California and Martinez encourage the use of native and drought-tolerant plants in landscaping. California Gov Code §65595 prohibits local governments from banning ornamental vegetation, including native plants. CCWD offers rebates for replacing water-intensive lawns with California native plants. Native plants generally require no irrigation once established and support local wildlife.

Removal of protected trees — including mature oaks, redwoods, and trees above a diameter threshold — typically requires a tree removal permit from the Planning Division with mitigation planting. Unpermitted removal carries substantial fines.
