What should developers know about Martinez zoning?
Martinez is a Contra Costa County seat with a genuinely mixed zoning portfolio - 59 districts spanning heavy industrial waterfront land, Environmental Conservation overlay zones, agricultural valley parcels, and a walkable downtown shoreline corridor. The city's largest single district is ECD-H-I (Environmental Conservation And Heavy Industrial), covering 673.84 acres along the waterfront, followed by M-OS/RF (Mixed Use Open Space And Recreational Facilities) at 566.03 acres - together these two districts account for more acreage than all residential zones combined. Developers will also find an array of ECD-R zones (Environmental Conservation combined with residential uses at R-40, R-80, and R-100 lot sizes), a dedicated Downtown Shoreline district (DS), and multiple M-prefix mixed-use overlays including M-R-1.5/CC (Multifamily Residential with Central Commercial) and M-NC/TC (Neighborhood Commercial with Thoroughfare Commercial).
For investors targeting industrial or flex uses, the H-I (Heavy Industrial, 341.72 acres) and L-I (Light Industrial, 62.88 acres) districts offer conventional options, while the large ECD-H-I waterfront zone carries environmental overlay requirements that shape site-level feasibility. Residential development concentrates in the ECD-R-40 (487.54 acres) and ECD-R-100 (355.23 acres) districts - both subject to Environmental Conservation controls that influence grading, landscaping, and biological resource review alongside the standard lot, setback, FAR, height, and coverage controls. Building controls across all districts include FAR, density, lot, coverage, pervious surface, lot width, and all setback categories.

Martinez zoning: frequently asked questions
What does the Environmental Conservation (ECD) overlay mean for residential development in Martinez?
The ECD prefix designates districts where standard zoning controls (lot size, setbacks, FAR, height) are combined with environmental conservation requirements. Projects in ECD-R zones must address biological resource protection, grading limitations, and potentially stormwater conditions beyond what a standard residential district would require. Entitlement timelines in these zones often run longer than in non-overlay districts.
Is the Downtown Shoreline (DS) district suitable for mixed-use or hospitality development?
The DS district covers 12.54 acres at the waterfront edge of downtown and is structured for mixed-use development integrating retail, office, and residential with public waterfront access. Hospitality and food-and-beverage uses are generally consistent with DS intent, though the city's design standards for this district are oriented toward pedestrian activation and visual access to the water.
What development opportunities exist in the Alhambra Valley-specific zones?
Martinez includes three Alhambra Valley prefix districts - AV/A-5 (Agricultural, 142.6 acres), AV/PD (Planned Development, 143.52 acres), and AV/R-40 (One Family Residential, 30.34 acres). The AV/PD zone at 143.52 acres is the most relevant for new projects, as planned development designation allows customized standards negotiated through an approval process, typically suited to larger residential or mixed-use master plan submissions.
How significant is industrial land in Martinez relative to residential land?
Industrial land is substantial relative to residential. The ECD-H-I district alone (673.84 acres) exceeds all ECD-residential districts in aggregate acreage, and the standalone H-I district adds another 341.72 acres. By contrast, total ECD-R residential acreage across all four sub-types sums to roughly 950 acres. This industrial-to-residential land ratio makes Martinez an active market for industrial and logistics users alongside its residential communities.
Do mixed-use districts in Martinez allow multifamily residential above commercial ground floors?
Yes. Districts such as M-R-1.5/CC (Multifamily Residential and Central Commercial, 1.54 acres) and M-R-1.5/PA (Multifamily Residential Professional and Administrative Office, 11.47 acres) explicitly combine residential and commercial uses. The city's M-NC series of districts also enables neighborhood-scale commercial with residential components. These zones are relatively small in aggregate acreage, so site availability is limited and competition for parcels can be significant.
