I know this is an old thread but... I started researching paint removal from stucco after buying our house in 2013. It has two layers of paint- the most recent is a faded cheap Barney purple acrylic and the first is a presumably oil based light gray. I too wish we could turn back time and stop both paint jobs before they happened. Especially the first, which was sprayed on by a less-than-competent painter who painted the slate roof along with the dormer's stucco. He then came back and painted over his mess with a 'slate gray' color- and you can imagine what our roof looks now... I still have a purple house but I have gone down many avenues in search for a solution. There are commercially available paint strippers that will do exactly what you need but they become incredibly expensive when you start looking at the amount needed to do an entire house. Dumond makes several lines of strippers for various surfaces and paint types. More prevalent now are the soy and citrus based strippers that are 'safer' but require multiple applications if there are multiple layers of paint. The good news is that there are more and more contractors specializing in large scale paint removal as more attention is being paid to the importance of restoration/preservation but also with the rise in repurposing industrial buildings throughout various urban areas for housing etc. I was given a quote by a company who sounded knowledgeable and experienced enough to do the job, but the price was simply too high for the house. Sand/media blasting is an option but as noted is a huge cost and mess. I went as far as to make my own alkaline based stripper and wasted a lot of time testing recipes and applications etc. It was labor and time intensive as well as messy and dangerous but cheap. Multiple applications were required but in the end the alkaline stripper disolved the underlying oil based coat, allowing the purple acrylic paint to be powerwashed off with a bit of effort. Still after all my trouble I only completed one gable before calling it quits. If your paint will come off just by powerwashing -without damaging your stucco- then by all means take advantage of that situation! Spend some time caulking around windows and doors with silicone (think of using big globs that you can peel out later), duct-tape between storm windows and frames and seal up any possible entry point for water. Mine wouldn't budge with power washing alone but after applying the stripper, I had luck using a rotary surface attachment on my powerwasher wand- it's designed for concrete driveways etc and is awkward to hold up against a wall but it greatly reduces the mess. I am now planning to use a mineral paint over our painted stucco. After working inside and out of this house for 5 years, I have concluded that the two poorly applied layers of paint aren't causing any serious issues with breathability- as long as they arent continuously added to! This house is old and drafty and there is plenty of ventilation behind our stucco as it doesn't reach below our brick foundation and is open into the soffits/eave cavities and roof system etc... It gets enough air. This is also helped by the fact our stud bays are not filled with insulation or foam, there are no vapor barriers, and our climate isn't terrible... Where are you now with your stucco project?

You have a lovely house ..white stucco with some charcoal grey with blue undertones for some trim areas and garage door would be very refreshing in a sea of beige to taupe track homes, a kind of California modern look. Changing the look of the garage door to either match your pergola color or a trim color will go a long way to update , giving you great curb appeal. The red tile roof gives you some thing to run with for bumping up the style. I would add some Saltillo tile for the porch and walkway to repeat that roof color , some new lighting that's larger in scale and some more structural plantings such as blue agave.

I'll also add that I've considered Dunn Edwards Crisp Muslin or Fine Grain as well.

So you may want to take some cues from this model home in south FLA where I live. Get rid of the stucco arch at the doorway and add columns. Add lots of wide trim as shown in the inspiration photo and possibly create an alcove to the front door. Landscaping will take it to the next level. Remove the window mullions if possible.
