New Construction Homes in San Dimas: Mostly Townhomes, 2027+

Four residential projects are working through San Dimas right now. Together they would add about 266 homes. Only 44 of them are detached houses. According to the city's own forecasts, no buyer gets keys to any of them before summer 2027. A buyer weighing San Dimas this fall is really choosing between two things: an existing house on the resale market, or a new townhome that won't be ready before summer 2027.

On the downtown parcel the city counted on for apartment-level density, the builder has asked San Dimas to lower the allowed density so it can build for-sale townhomes instead.

The pipeline, project by project

The largest project is Bonita Avenue Townhomes, built by MW Investment Group through San Dimas Bonita LLC. It sits just east of 444 E. Bonita Avenue on the former U.S.D.A. Forest Service Technology and Development Center site. The plan is 164 attached two- and three-story townhomes in nine floor plans, from 1,286 to 2,036 square feet. Seventeen units are set aside for moderate-income buyers. City Council approved the vesting tract map on October 14, 2025. The city's development projects page lists it as under construction, with first homes expected in summer 2027 and full completion in fall 2029.

Lantana at Regent Court, from RC Homes, is the only sizable detached project. It has 37 two-story homes in three plans, from 1,810 to 2,197 square feet, each with a two-car garage. Seven of the homes are affordable units. The site previously held two residences, a garage, and a barn. The city now lists it as under construction, with first homes in fall 2027 and completion in summer 2028. The RC Homes Lantana page expects to open a sales office in summer 2027 and says interest-list registration is "coming soon." It shows no prices.

Cherokee Court is seven detached two-story homes at 327 E. Baseline Road and the vacant lot just north of it. Buyers can choose between two floor plans, each offered in Spanish or Italianate styling.

Across all four projects, 222 of the 266 homes are attached. That is roughly five of every six new homes on the way.

The parcel that was supposed to hold apartments

In September 2024, San Dimas adopted its Downtown Specific Plan, which rezoned the area around Bonita Avenue and the A Line station. The plan was meant to support the city's 2021–2029 housing goal of 1,248 units. One of the sites the city counted on is Site 7a, a vacant 2-acre parcel at 442 W. Bonita Avenue and 204 S. Eucla Avenue, zoned DTSP-Town Core.

The city's draft Housing Element amendment describes the site as "ripe for development" because of its vacancy, its proximity to the A Line, and the owner's interest. The site summary in that document still lists the anticipated use as "MF/Apartments." The application staff are actually processing is for 58 townhomes, six of them sold to moderate-income households. The developer has asked the city to lower the site's density range from 35–45 units per acre to 25–35.

The arithmetic is simple. At the original range, two acres would have held 70 to 90 homes. At 58 homes, the project works out to 29 units per acre. That fits inside the lower band and falls below the bottom of the old one. Three-story townhomes with their own entries use more ground per home than a stacked apartment building does, so the density range had to come down before this kind of product could fit on the parcel.

The plan's design rules point the same way. Town Core covers the historic Bonita Avenue commercial core, generally from Cataract Avenue to San Dimas Avenue, and it directs new buildings to reflect the area's historic scale and character. The denser, transit-oriented zoning belongs to a separate district next to the station, called Transit Village. On the Town Core parcel being decided now, what is moving forward is ownership housing at a modest scale.

The request is not final. The city's May 21, 2026 notice took public comments through June 1 and said the Planning Commission and City Council would hold hearings later. We could not confirm any decision since then, so until a vote happens, the 58 homes remain a proposal.

What the calendar means for a buyer this fall

Put the city and builder dates in order, counting from October 2026:

1. Summer 2027: first Bonita Avenue Townhomes and first Cherokee Court homes expected; Lantana sales office expected to open.
2. Fall 2027: first Lantana homes expected.
3. End of 2027: Cherokee Court expected to be complete.
4. Summer 2028: Lantana expected to be complete.
5. Fall 2029: final Bonita Avenue Townhomes expected.

The city's construction page warns that schedules can change with little or no notice, and the forecast dates on its project listings carry no publication date. Read them as targets, not commitments.

The key point for detached buyers is that 44 new houses are spread across two projects, and the earliest of them is due no sooner than summer 2027. None of the builders has published a price, so no one can yet compare a new San Dimas home against a resale house on cost. For the next several seasons, a buyer who wants a detached house with a yard in San Dimas will be choosing from homes that already exist.

The countywide market gives some context for how much pressure that puts on a buyer. In August 2026, the median price of an existing detached single-family home in Los Angeles County was $946,950, up 1.7% from August 2025, according to the California Association of Realtors. In the same release, the county's median time on market was 30 days, compared with 28 a year earlier. Those figures describe the whole county, not San Dimas. They show a market that is rising slowly and holding steady, not one where buyers have to commit within days. A buyer can take time to evaluate resale houses on their merits, knowing the new detached supply is small and not due before summer 2027.

For buyers who prefer a townhome, the timing is different. Bonita Avenue Townhomes alone will deliver 164 homes in phases from mid-2027 through fall 2029. A Town Core townhome on Site 7a, if approved, would sit within walking distance of the A Line. On the line's first anniversary, the Foothill Gold Line Construction Authority reported that Metro ridership on the line was up more than 14% since the four stations from Glendora through Pomona opened. A commuter who can wait has real new options coming, spread across several years. Our guide to San Dimas for A Line commuters covers that side of the decision.

Owners already in San Dimas who plan to trade into one of these projects face a sequencing question with no dates attached yet, because a sales office opening is not a closing date. Our post on buying before you sell in San Dimas explains how that kind of overlap generally works.

Questions buyers ask about San Dimas new construction

Have prices been announced for any of these projects? No. The RC Homes page for Lantana lists no price range, and we found no published pricing for Bonita Avenue Townhomes, Cherokee Court, or the Site 7a proposal.

Can I join an interest list? RC Homes says Lantana's interest-list registration is coming soon. We found no interest-list or sales-office timing for the other three projects.

Are any of the new homes income-restricted? Yes, some. Bonita Avenue Townhomes includes 17 moderate-income units, Lantana includes seven affordable units, and the Site 7a proposal includes six moderate-income units. The specific qualification terms were not in the documents we reviewed.

Has the Site 7a density change been approved? We have not confirmed any approval. The city said Planning Commission and City Council hearings would follow the public comment period that ended June 1, 2026.

Who builds Cherokee Court? The city's project listing does not name the builder, and we did not find the name elsewhere.
