Milpitas Neighborhoods by Their Lots: Lot Sizes, House Sizes, Flood Zones and Fire Zones

The City of Milpitas’s public parcel records give the zoning, an outline and the county assessor’s building square footage for every parcel in the city. We took the 11,262 parcels zoned single-family (R1) with a building on them, measured each lot from its outline, placed it in our neighborhood guide outlines, checked its center against FEMA’s flood map and checked each lot against CAL FIRE’s fire hazard severity zone maps. The records don’t list year built or stories, so this post is about lots, house sizes, flood zones and fire zones. The figures come from City of Milpitas parcel records (inside city limits), October 2026. There are no addresses or owner details here.

The short answer

• Citywide, among parcels zoned R1 with a building, the median lot is 5,980 sq ft and the median house has 1,630 sq ft.
• Largest and smallest lots (guides with at least 150 houses): largest in Park Victoria (6,230 sq ft), Milford Village & Piedmont (6,200 sq ft) and Milpitas Manor & Curtner (6,120 sq ft); smallest in Starlite Pines (5,000 sq ft), Parktown (5,640 sq ft) and Town Center & Hidden Lake (5,730 sq ft).
• Biggest and smallest houses (the same guides): biggest in Town Center & Hidden Lake (2,180 sq ft) and Milpitas Hills (2,080 sq ft); smallest in Starlite Pines (1,340 sq ft) and Milpitas Manor & Curtner (1,370 sq ft).
• Flood zones: 1,893 of the 11,262 houses (17%) have their parcel center in a FEMA high-risk flood zone (849 in AE, 702 in AO and 342 in AH), all of them inside our guides. Milpitas Manor & Curtner alone has 1,005, 79% of its houses.
• Fire zones: 748 houses (7%) have part of the lot in a CAL FIRE fire hazard severity zone, all Moderate; none are High or Very High. The most are in Park Victoria (332) and Milpitas Hills (232).

Neighborhood by neighborhood

Largest median lot first. “Houses” counts parcels zoned R1 with a building inside each guide’s outline; “house size” is the assessor’s building square footage. Each name opens its guide. Milpitas Metro (BART & Great Mall) has no R1 lots: its homes are townhomes and condos in other zoning districts, so it’s left out of the table.

The “All of Milpitas” row also counts the 21 houses outside the neighborhoods above.

What stands out

• Flood zones are a big part of the story. Milpitas Manor & Curtner and Starlite Pines hold 1,403 of the city’s 1,893 high-risk houses (74%).
• Every house in Midtown & Main Street has its parcel center in a high-risk zone: all 100, in zone AE.
• Town Center & Hidden Lake has the biggest houses, a median of 2,180 sq ft, on a median lot of 5,730 sq ft, smaller than the citywide 5,980 sq ft.
• Lot sizes are fairly even. Every guide with at least 150 houses has a median lot between 5,000 sq ft and 6,230 sq ft.

Flood zones, neighborhood by neighborhood

Houses in FEMA high-risk zones inside each guide’s outline, the share of the guide’s houses they make up, and the zones; most first. The other two guides in the table above have none.

What the flood zones mean

• Zone AE: a 1%-a-year chance of flooding, with a base flood elevation set.
• Zone AH: shallow ponding, usually 1 to 3 feet deep, with the same 1%-a-year risk and a base flood elevation.
• Zone AO: shallow flooding, usually sheet flow, 1 to 3 feet deep, with the same 1%-a-year risk; FEMA gives a flood depth instead of an elevation.
• Zone X: moderate to minimal risk, outside the 1%-a-year floodplain.
• Insurance: if the house itself is in an A or V zone, lenders on federally backed mortgages require flood insurance; a flood zone determination for the address settles it. In zone X it’s optional.

Fire zones

Every Milpitas house in a CAL FIRE fire hazard severity zone is in a Moderate zone, counted by the highest zone that touches any part of the lot: 332 in Park Victoria, 232 in Milpitas Hills, 104 in Parktown and 80 in Milford Village & Piedmont. The other five guides have none.

Reading it right

• Zoning isn’t use. We counted parcels zoned R1 with a building; a few may hold a second unit, and houses in planned-development or other districts aren’t counted.
• House size is the assessor’s building square footage, which can miss recent additions. Check permits for any house you’re buying.
• Lot sizes are measured from the city’s parcel outlines, so they can differ from a survey by a few percent.
• We checked the center of each parcel against FEMA’s National Flood Hazard Layer. A lot can straddle two zones, and maps change, so check the current FEMA map for the exact address.
• The flood zone covers the land, not the house. A house can sit above the base flood elevation even in a high-risk zone. An elevation certificate settles it and can lower the insurance price.
• The fire zone describes the land around a house, not how the house is built. CAL FIRE’s zone viewer shows any parcel.
• A median isn’t a verdict. It describes the lots and houses, not which neighborhood is right for you.
