Comparing Sunnyvale homes becomes more useful when the question moves beyond detached versus attached. A detached house may carry several generations of altered space. Two developments described as townhomes may divide their property differently and assign different duties to an association. A floor-area figure may include the garage. These differences affect how you use, investigate and maintain the property, even before price enters the conversation.
Three actual public files make those distinctions concrete: the existing house at 1413 Bedford Avenue, the approved 494 South Bernardo Avenue townhome proposal and the approved 845 Stewart Drive condominium proposal. The latter two are planning examples, not a claim that finished homes are available for sale. This comparison uses records checked October 26, 2026. It does not substitute for recorded title, a current inspection or a visit to an actual offering.
Start with what is owned, then examine the building
The Sunnyvale housing guide introduces comparing the full offering. Here, the next step is to divide that offering into the private interior, exclusive outdoor areas, shared facilities and routes used to reach them. The Santa Clara County guide provides the wider context, but a countywide label cannot resolve a particular driveway or maintenance boundary.
At Bedford, the City report describes an existing one-story home on approximately 9,910 square feet beside Stevens Creek. Its public permit history includes a 1958 house-and-garage entry, a later garage conversion and several component improvements. That is an existing-house investigation: establish which spaces and systems are present, how they changed and what the records support. A lot-size number alone does not show where outdoor activities fit around buildings, access, drainage or other constraints.
At Bernardo, the approved map proposal creates 28 individual lots and one common parcel. At Stewart, the approved proposal creates 28 condominium units. Both involve three-story townhome-style buildings, yet their maps describe different ownership arrangements. Neither appearance nor the word townhome is enough to identify who owns the land beneath a building, who controls a common route or how repairs are allocated. Obtain the actual recorded map and governing documents for the property being considered.
Bedford: a house history and a separate future scope
The Bedford planning report describes proposed first- and second-story additions plus a 714-square-foot attached accessory dwelling unit. The primary dwelling’s reported 3,567 square feet includes 3,083 square feet of living area and 484 square feet of garage. The ADU is separately stated. Combining all these numbers under one living-area heading would create a misleading comparison.
The current public portal marks planning file PLNG-2025-0804 Approved, with a complete date of August 24, 2026. That establishes a planning-record status, not that the proposed addition and ADU have been built, inspected or occupied. The historical permit search also contains finaled electrical and seismic-retrofit entries. Their existence does not convert the separate addition proposal into completed construction. Keep the existing building, completed component work and approved future scope in different columns.
For a buyer who wants a largely private outdoor setting, Bedford’s file suggests specific questions rather than a lifestyle promise. Where do the existing and proposed footprints sit? Which routes remain available during major work? How would the ADU and primary dwelling use outdoor space? What do approved drawings and qualified reviewers say about the creek-adjacent site? The public report identifies the setting; it does not answer a present drainage, boundary or engineering question.
Bernardo: individual lots with common circulation
The Bernardo report describes 28 homes in six three-story buildings on 1.45 acres. The Planning Commission’s published final minutes show approval on August 10, 2026. Two driveways connect to West Olive Avenue through a U-shaped drive aisle; pedestrian connections are described from both Olive and Bernardo. These are useful plan facts for evaluating how vehicles, visitors and people walking would share the site.
The visitor-parking detail matters more than a headline count. Of eight visitor spaces, one has a daytime-loading and nighttime-guest function. That is not eight unrestricted guest spaces at every hour. A future buyer should compare the approved plan with actual signs, operating rules and the recorded parking rights. Someone needing daytime visitor access should test that need directly instead of treating a two-car garage as a complete parking solution.
The report’s unit areas range from 2,542 to 2,696 square feet and include attached two-car garages. Compare usable interior area and circulation separately. Three stories can put useful separation between activities, but the practical result depends on where rooms, entrances, storage and laundry fall. A plan review should trace ordinary tasks from car to kitchen and bedroom to exit. Those are household-specific tests, not a ranking of one building type as universally better.
Stewart: condominium form with duties beyond the interior
The Stewart report describes four three-story buildings on 1.16 acres. Published final minutes show approval on January 26, 2026. Its corrected approval conditions require a mandatory association and describe maintenance obligations for common facilities and private utilities. Those conditions provide a strong reason to investigate shared infrastructure even where a unit presents like a separate house.
The corrected conditions also address parkstrip landscaping and sidewalk maintenance along the public frontage, stormwater facilities and association consent for common-area modifications. Public frontage does not automatically mean the association has no maintenance duty. The actual recorded documents and completed improvements must establish the final arrangement. Planning conditions are neither an association budget nor proof every condition has been fulfilled.
Existing house → component permit history → separately approved addition/ADU plan
Approved townhomes → 28 individual lots plus common parcel → shared circulation questions
Approved townhome-style condominiums → 28 units → association infrastructure questions
| Anchor | Verified distinction | Decision to investigate | Document still needed |
|---|---|---|---|
| 1413 Bedford | Existing house; approved plan separately states living, garage and ADU areas | Existing versus proposed use, outdoor utility and component condition | Approved drawings, current inspection and title/site evidence |
| 494 South Bernardo | 28 individual lots and one common parcel; two West Olive driveways | Common route duties; daytime loading versus nighttime guest space | Recorded map, access/parking rights and actual association rules |
| 845 Stewart | 28 condominium units; corrected conditions assign common/private utility and frontage duties | Who maintains facilities and how expenses reach the owner | Recorded CC&Rs, maintenance map, budget, reserves and insurance |

Approved proposals are not completed inventory. No field observations, recorded title conclusions or private financial review are claimed.
Compare obligations that can change daily use
Keep the condition of the surrounding property separate from the condition of a candidate unit. At Bernardo, the planning report describes a former office and childcare building, not 28 long-established residences with a known repair history. At Stewart, the former commercial building’s 1974 date does not date the proposed homes. A comparison that imports the old site’s construction year into a future unit profile would confuse two different assets. Record what existed when the report was written and what the approved proposal would replace.
The sequence of control also deserves its own column. Stewart’s corrected conditions describe developer responsibility before the association takes over and require management information at the transfer of autonomy. A public approval therefore raises a timing question: which entity controls and maintains the common property at the actual purchase date? A finished-unit inspection alone cannot answer that. Request the transfer records and current management contacts, then confirm whether the budget and insurance materials correspond to that same stage rather than an earlier projection.
For each setting, write one nonnegotiable need in practical terms. Someone requiring a room without internal stairs should locate that room and its access on the actual plan. Someone expecting independent workshop use should confirm the allowed space, utility arrangements and alteration rules. Someone planning an ADU should separate an approved example from entitlement for a different parcel. The three public files show why these questions arise; they do not provide blanket permission or establish suitability for a particular person’s circumstances.
Utilities offer another useful distinction. Stewart’s conditions call for private water submeters unless otherwise approved. A submeter can measure unit consumption without being a separate City retail account. Ask who receives the provider bill, how common consumption is allocated, who maintains the meters and what happens when a leak occurs between shared and private components. The answers belong in the property comparison beside parking and storage, not solely in a later discussion of monthly dues.
Use a separate maintenance sketch for each candidate. On an existing house, identify the roof, drains, electrical equipment, altered rooms and outdoor improvements that require evidence. In an attached development, add shared circulation, private utility networks, landscaping and any stormwater equipment. Then mark the responsible party and the document establishing that duty. An empty responsibility cell is a question to resolve; it is not evidence the cost disappears.
Finally, compare actual routes at the time you expect to use them. These records identify access connections, not measured commutes, transit frequency or present conditions on every approach. Visit the specific offering, trace deliveries and visitor access, and check current route information against your own destinations. Carry the resulting document questions into the buying process. A useful Sunnyvale comparison ends with a clear account of the space, rights and recurring responsibilities being acquired.
