Commercial Real Estate in Morgan Hill: Downtown Mixed Use, Highway Commercial and the RDCS

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

Morgan Hill’s commercial property runs along three spines: the downtown blocks on Monterey Road, the rest of the Monterey Road corridor north and south of downtown, and the freeway frontage along Highway 101, plus the city’s industrial districts. What makes the city different for an investor is its long-running Residential Development Control System, which governs how fast housing, including the housing in mixed-use projects, can be built. Confirm the zoning, any specific plan and allotment status for each parcel with the Morgan Hill Development Services Department.

Who controls the parcel

Inside city limits, Title 18 of the Morgan Hill Municipal Code governs zoning. The zoning code was rewritten by Ordinance 2277 N.S., adopted June 6, 2018, and amended since. The RDCS sits in its own division of Title 18. The city is ringed by unincorporated County land, including San Martin to the south, where County zoning and the County’s urban service area rules apply. The RDCS ties growth to the city’s urban service area, so a parcel outside it faces both annexation and allotment hurdles. See our Santa Clara County commercial guide and San Martin commercial page.

Morgan Hill zoning for commercial, industrial and mixed use

The commercial chapter does not set floor area ratios; it uses maximum building coverage instead. Use tables in the chapter were amended as recently as Ordinance 2362, adopted February 19, 2025.

Downtown and the Monterey Road corridor

Downtown. MU-D exists to keep downtown the city’s center, with active storefronts and a mix of commercial, residential and public uses, and it implements the Downtown Specific Plan. Heights run to three stories and 45 feet, or four stories and 55 feet on sites of 22,000 square feet or more. The district has no density minimum or maximum, but the plan, not the zoning chapter, decides which uses are allowed on each block, so read its use figure before signing a lease.

Monterey Road. North and south of downtown, MU-F allows vertical or horizontal mixes of commercial and housing at 7 to 24 units an acre. However, residential and residential mixed use are not allowed until a Monterey Corridor master plan is completed, and Chapter 18.29 adds a form-based code for the corridor. For now, treat MU-F sites as commercial sites with possible future housing upside, and ask Planning where the master plan stands.

Highway 101. CH is the city’s freeway frontage zone and the only commercial district that allows four stories. Hotels, restaurants, wine tasting rooms, vehicle rentals and vehicle sales are permitted outright, while freight terminals need a conditional use permit.

The RDCS and other Morgan Hill rules

• Growth control. Chapter 18.156 traces back to Measure E in 1977. Its current version, Measure S of 2016, caps population at 58,200 on January 1, 2035 and allows up to 215 allotments a year through a scored competition. Residential units in a mixed-use project generally need an allotment.
• Downtown set-aside. The RDCS reserves 500 downtown allotments through 2035, no more than 100 a year, issued first-come, first-served to projects scoring at least 80%. This makes downtown the easiest place to add housing over retail.
• Use it or lose it. Allotments must be exercised within 30 months of approval or by a development agreement date, with at most one extension of up to a year for city-caused delays or severe natural events.
• Residential transitions. Commercial sites next to residential zones must meet the transition standards in Section 18.92.130, including setbacks, upper-story stepbacks and landscaping.
• State law. State housing laws adopted since 2019 limit how cities may cap housing; ask the city how it currently applies the RDCS to your project.

Transfer tax, business tax and property tax

• County documentary transfer tax. The County’s real property transfer tax chapter charges $0.55 per $500 and credits a conforming city tax at half that rate.
• City documentary stamp tax. Morgan Hill’s Chapter 3.16, from Ordinance 223 N.S. in 1967, sets 27.5 cents per $500 under the state enabling law and is administered by the County Recorder. That is the half rate the County credits, so the combined total should remain $0.55 per $500; confirm on the escrow estimate.
• Business tax. Chapter 5.04 covers the city’s business taxes and licenses; we did not verify rates. Hotels pay transient occupancy tax under Chapter 3.24.

A change of ownership generally triggers Proposition 13 reassessment.

Due diligence that matters in Morgan Hill

Start with our commercial due diligence checklist, then add:

• Confirm the parcel is inside city limits and the urban service area.
• Downtown, check the Downtown Specific Plan’s use figure for the block.
• On Monterey Road MU-F sites, ask about the corridor master plan before paying for housing potential.
• If a project includes housing, confirm the RDCS path: competition, downtown set-aside or an exemption.
• Check the residential transition standards on sites that abut homes.
• Verify CUP status for drive-throughs, fuel and liquor uses in CN.
