I think it is so personal; there are pros and cons to both!
I guess it would depend on so many things; your building site, financing, style and your plans for the future. So many variables and there is no right or wrong only what you want!
As for resale, you may want to ask a few real estate agents in the area you plan to live.
Good Luck!

Here I prefer stick due to the winter, freezing well below 0, and hot summers, with A/C also due to tornadoes and straight line winds. I very seldom hear the wind, and my friends have a modular and hears it all the time. But then we have a basement and she does not. She is on the west side and we are on the east side, so the town breaks the wind, sometimes. If you do have the modular built, make sure you use hurricane strapping if you have winds. Are you in a earthquake area? This make a difference too. If they have dry wall inside, they will be better built, but more expensive. My DD had that in CA..

There are no differences between stick built and modular built homes nowadays.

Not even in resale. A modular home built with the same amenities as a stick built home will cost about the same and sell for the same.

Both types are constructed of the same materials and to the same building code standards.

Modular homes have advantages stick built homes do not which include:

-climate controlled construction
-speed of site construction
-better quality control

You can order a 1000sf modular home or a 6000sf modular home.

Modular homes today are not 'trailers', but fully comparable to stick built construction in every way.

I looked into modular, but couldn't come up with a floor plan that was even close to what I wanted. Not available in this area, anyway. The companies I talked to were very limiting on how much customization they were willing to do on floor plans.

We looked into modular also and our problem came down to the limitations in room sizes. We ended up going with preformed concrete walls. It gave us the flexibility we wanted and the cost was comparable to modular.

Find a reputable modular company. An inspector won't tell the difference until they look in the attic.

Manhattan--you are wrong. In CA modulars are state regulated and the codes are different that stick built which are either city or county regulatated. Hubby is retired building inspector from CA. Depending on who makes the modular, how well built. In tornado/straight line winds, modulars are sometimes just picked up and stick builts are usually smashed, and yes picked up. Modulars are usually just sit on bases,(piers) usually tied down, but very seldom just sit on a flat base. Speed, yes! Quality sometimes, not sure what you mean by climate control construction. Would I live in one? NO.
I saw what happened to too many in the earthquakes in CA and tornados here.

Mariend, In ca., modulars are required to be on a "permanent" foundation similar to a crawl space foundation and are required to have earthquake tie downs to footings under the unit. They also are required to have 2x6 exterior walls, minimum required r-value insulation, dual pane windows, energy star ratings for appliances, etc. all similar to residential requirements for a home. Even at that, you'll never get the quality in a modular, especially when it comes to re-sale value of a stick built, icf, sips home, single family dwelling. Climate control construction simply means it is assembled in an indoor factory environment which is a plus, but again imo, nowhere near the quality of being a true "home". My brother and sis-in -law bought one on property. Continous run soffit venting, continous run ridgeventing, fiber cement siding as well as some other impressive features that you never saw in a mobile home, trailer house, modular, or whatever else you want to call them in the past, but overall not a quality "build", again, imo.

Thank you for clarifying the construction. One of my main points was that state inspection is not as strick as Los Angeles County where hubby worked. My dd did buy a modular and it had sheetrock which at that time was very unusual.

Modular homes should not be confused with mobile homes, trailers, or double-wides. They are not the same thing.

Modulars are built to the same standards as stick built homes and have come a long way since the days when one could not tell modular homes apart from mobile home trailers.

In most States, modulars are now manufactured and inspected to the same Building Code standards as are stick built homes.

While there may be some restriction on modular sizes that can be shipped, larger rooms can be shipped unassembled and erected on site.

Modular quality equals stick built quality in all ways if one pays for and requests the same materials as go into a stick built home. That modular quality is inferior to stick built is nothing more than a myth.

One gets what one pays for in a stick built or modular home without difference.

Resale value is equal to that of stick built.

There are low end modulars you can buy for under $100,000 and there are high end modular you can buy for several million.

After touring the factory (Nationwide) and being present while three homes were set, I bought a modular and have no regrets. Recently in my area, a tornado hit a 4-unit, two story modular along with other houses. One of the top floor units was toppled, the other top floor unit was moved around but not toppled and the base units had minimal damage. The owner rebuilt with a replacement modular unit.

Out here they are calling what used to be termed mobile homes, where they are transported to the site by way of having wheels and axles, as modulars. What Manhattan refers to are modulars built and trucked to the site and set on the foundation by use of a crane and I agree they are as equally and in some respects superior to stick built homes due to conditioned construction. I might have confused the op's question as talking about modular,(mobile homes), that, imo, are far more inferior than a stick built. If that's the case, I apologize for the confusion.

Modular, prefabricated, and panelized all connote different construction methods, and it would probably be useful to link to examples of each.

Modular and prefab end up as variations of one theme: a box; with panelized any shape is possible.
Modular/prefab have speed on their side, absolutely. IOW the guys that are stapling them together are all on speed ;-)

Legal definitions also apply.

In my state 'mobile homes' are defined as manufactured housing while 'modular homes' are defined as industrialized housing.

Big difference because mobile homes are legally constructed to older HUD standards while modular homes are constructed to the same legal Code standards as stick built.

It still amazes me how much confusion there is about modular. I think the mobile home (trailer industry) has most people thinking that they are the same as trailers. A modular built home is a stick built home that is 90% completed off site and transported to a permanent home foundation. There are some differences but they are in the buyers favor.
Example:
*licensed architects
*quality control inspectors
*3rd party state building inspectors
*20 to 30% more lumber
*on average,code requirements are met 16% above state limits
*usually able to withstand high wind and earthquakes better than "site built" homes
*no cost overruns and shorter time to move in
*built in a drug free environment by supervised workers
A good analogy would be;would you rather buy you car from a factory or would you rather have it assembled on a vacant lot by a bunch of loosely supervised sub-contractors?

Yes there is a lot of confusion on here...Modular and Manufactured homes are not the same!!!

Modular homes are almost always built according to local code.

Manufactured homes (double wides, etc.) are built according to HUD codes.

"Manufactured homes (double wides, etc.) are built according to HUD codes".

And in our state are registered with the Department of Motor Vehicles same as a vehicle or trailer. Put pontoons on 'em and call them a house boat!

Unfortunately our modular build has been a total disaster. We utilized Nationwide Homes for our build and have received "zero" support from them. It is ironic that modular companies promote "climate controlled" construction and then drive the modules down the highway through monsoon rains. Then after delivery you are left with a partially completed roof that proceeds to leak into your finished modules until your contractor gets his act together and "dries" you in. (that usually happens within a few months). Keep in mind that with all the drywall, insulation, wiring and plumbing installed all this moisture presents a serious mold threat.
As for the "pace of construction", all I can say is that most subcontractors show up and "scratch their heads" wondering where they fit into this picture. After all you have 70% of everything done. The contractors recognize that they are responsible for blending existing with new much the way they would in a remodeling project. Unfortunately their effort required to do so is reflected in their pricing and interest
.
The bottom line is that our modular consisted of substandard framing work, horrific drywall and trim work and a nightmare of logistics for finishing the project. The house has been saturated with moisture in unknown places and presents a serious mold threat. All this was accompanied by no support or follow up from Nationwide Homes. At this point we can only pray for some sort of relief and keep putting money into a structure that may or may not be habitable.

If the only option I had was to build a modular or prefab house I would rather live on the street. I have nothing against manufactured housing, it's just my personal preference to avoid it while I am alive. You can incinerate me in whatever you like when I am dead.
