Read this from my previous posts and both projects are the worst choices:
Detached condo is a much better for the money spent. You do pay a premium of up to 10% but you do get window on all four sides of your home and you do have a side yard and a patio backyard while town homes backyard is often at some really awkward location like at the front of the home that looks really good when presented in the model homes but no one really uses it in real life. BBQ should be a backyard activity.
Because side yards are dedicated for house separation the footage of the detached home is smaller than the town home where the side yards are filled in as footage. I like the side yards better for some privacy buffer. You will still hear the noise but you can mitigate this by planting a columnar type tree in between. In a town home situation, you will hear the headboard banging in the middle of the night while in these detached condos master bedrooms are positioned away from the neighbors. In a town home situation sharing the bed wall could not be avoided.
The bedroom sizes are actually bigger in the detached condo compared to town homes at the similar price range. Even though a town home offers more footage the area is extremely wasteful in the long hallways and circulation. The secondary bedrooms are actually smaller than the detached condo by 3 feet.
Garage in Irvine is 20? wide standard and builders would never build an oversize garage because the selling price of the home is governed by the livable area. The 2 secondary bedrooms must fit across this 20? garage dimension as a result the bedroom width is about 9?-9" for each.
Termite infestation spread is a problem for town home. The entire building has to be treated even your unit has no sign of termite presence. One could not sell their unit if the complex is in litigation. It is against the law for the seller to sell his unit without disclosing all the previous litigations and construction defects that took place. Potential buyers are scared of these things. These legal issues are a hindrance for resale of attached units whereas the homeowners of detached condo could sell their home anytime.
Potential water damage, electrical malfunction, structural damage, and fire are intertwined for town homes. The most alarming is all the town homes are integrated together and share one common roof. One could theoretically crawl through the common attic across each ceiling of all the adjacent units and drill a small hole, install a small probe camera lenses and watch everything that you do in your master bedroom. Sometime in between the units the wall does go all the way up the underside of the roof for fire separation but this plywood wall could be easily cut manually and quietly with a manual coping saw.
Buying a town home with a little more wasteful footage for the same price for a detached condo is not worth the headache due to the negative baggage that comes along with the town home.
