California Mobile Home Park Market Data: Parks, Lots and Lot Rent

Mobile home park market size in California

California has roughly 3,900 mobile home parks containing about 460,000 lots, which works out to an average of roughly 118 lots per park. That makes California the 3rd-largest state by park count and the 3rd-largest by lot count among the 50 states in this dataset.

Put in national terms, California holds about 8.5% of the roughly 45,740 parks and 11.5% of the roughly 4,012,300 lots tracked nationwide. The average park size of about 118 lots is a useful yardstick: a target park well above it is an institutional-scale asset, while one well below it is a small operator-owned community with different financing and management dynamics.

These counts are estimates compiled from U.S. Census manufactured-housing data, MHI reports, and state-level MHP surveys, and they move slowly — new parks are rarely built, and existing parks leave the count mainly through redevelopment. Treat them as a planning baseline for the West Coast market, not a precise census.

Lot rent levels in California

Average lot rent in California runs approximately $950 per month, which is about $473 above the national median and ranks California 2nd-highest of the 50 states. Lot rent is the single most important number in an MHP model, because it is the recurring revenue line that occupancy and rent growth both act on.

The statewide average is a starting point, not a price-setting input. Lot rents vary widely by submarket within California: metro-area parks commonly run well above the state average, while rural parks often sit below it. When you benchmark a specific park, weight it against comparable communities in the same submarket rather than the state number.

Because California sits in the West Coast region, its rent level reflects that region's cost of living, land supply, and demand for affordable detached housing. Rising site-built home prices and rents continue to push households toward manufactured housing, which supports lot-rent stability even where headline growth is modest.

The size of California's lot-rent economy

Multiplying California's roughly 460,000 lots by the average lot rent of $950 per month implies an aggregate lot-rent economy on the order of $5.24 billion per year. This is a derived estimate, not a surveyed figure: it assumes full occupancy at the average rent, so real collected revenue is lower and varies with vacancy and the spread between low and high rents across the state.

At the individual-park level, an average California park of about 118 lots at the state-average rent would gross on the order of $112,100 per month in lot rent before expenses, vacancy, and any park-owned-home income. Actual results depend heavily on occupancy, the tenant-owned-versus-park-owned home mix, and utility cost recovery.

The reason this math matters is that MHP is valued on stabilized net operating income. Small, durable moves — filling a few vacant lots, recovering water and sewer costs, trimming turnover — compound across a park of this size, which is why operators focus on occupancy and expense discipline rather than one-time rent spikes.

Regulatory climate and the California investment picture

California has statewide rent regulation reaching mobile-home lots, and that fact sits at the center of any acquisition model. When the pace of lot-rent growth is capped, value creation shifts away from aggressive rent increases toward infill of vacant lots, occupancy gains, expense control, and utility cost recovery. Lenders and buyers price the capped rent trajectory in, which tends to hold pricing slightly more conservative than in unregulated states of similar size.

The upside is predictability: a statewide rule means one compliance playbook across the whole state rather than a patchwork of local ordinances. For a multi-park California operator, that uniformity lowers the cost of running the portfolio and makes performance easier to forecast.

On valuation, a word of caution about cap rates: brokers have reported stabilized manufactured-housing-community cap rates nationally in a broad band roughly from the high-5% to the mid-7% range through 2024 to 2026, but that is an industry-wide, national band and not a California-specific figure. Where a particular California park prices within it depends on its size, occupancy, home-ownership mix, financeability, and the rent-regulation factors above. Anyone quoting a precise California cap rate should be able to show you the comparable sales behind it.

Market data at a glance in California

• Park count
  About 3,900 mobile home parks — 3rd-most of the 50 states, roughly 8.5% of the national total.
• Lot count
  About 460,000 lots — 3rd-most nationally, roughly 11.5% of tracked lots.
• Average park size
  Roughly 118 lots per park, a benchmark for spotting institutional-scale versus small operator-owned communities.
• Average lot rent
  About $950 per month — 2nd-highest of the 50 states and about $473 above the national median.
• Aggregate lot-rent economy
  On the order of $5.24 billion per year at full occupancy (a derived estimate: lots times rent times 12).
• Region
  California sits in the West Coast region, which shapes its cost structure and housing demand.
• Rent regulation
  Statewide rent regulation reaches mobile-home lots; value-add leans on infill and occupancy, not rent ratchets.
• Data caveat
  Counts are slow-moving estimates from Census, MHI, and state MHP sources; benchmark specific parks against same-submarket comps.

How operators and investors use this data in California

• Benchmark, then localize
  Use the California averages as a first screen, then re-underwrite each park against comparable communities in its own submarket rather than the state number.
• Underwrite to occupancy, not rent spikes
  With an average park near 118 lots, filling vacant pads and recovering utility costs usually beats chasing headline rent growth — especially where rent is regulated.
• Model the regulatory brake honestly
  Reflect California's rent-control posture in your rent-growth assumptions, and read the California rent-control and lease-law guides before finalizing a business plan.
• Distrust precise cap-rate quotes
  Treat any exact California cap rate as a claim to verify against real comparable sales, since national bands do not translate cleanly to a single state.
• Watch the slow supply story
  Because new California parks are rarely built and lots leave mainly through redevelopment, existing communities hold scarcity value; track redevelopment pressure in your submarkets.
• Track lot-level data in Lotly
  Lotly tracks California lot-level occupancy, rent, and infill stage so your real numbers replace these statewide estimates in day-to-day decisions.
