I'm thinking of buying a lot south of Ensenada. I would like to know what the process is to be able to build a house that would be legal. What is the permit process?
Cost?

I suggest that if you are looking for a house in Ensenada, you try the Baja Country Club. Outstanding houses and great deals. You can also buy a lot and have a place constructed using your own builder. Check out:

The developer of the Baja Country Club has been the leading builder in Rosarito for years; his development there is Club Marena. We've owned in Club Marena for years, and I can assure you everything is well built and meets or exceeds U.S. standards. Prices at Baja Country Club have already gone up once; no doubt as "the season" gets underway, they'll go up again. I'd look soon if I were you.
