We're building a house down here in Georgia and the siding installer didn't put flashing between the brick wall (3 ft tall) and hardi siding band above. All the other houses have that flashing but he said they didn't need it because the drip edge on the top of the band will prevent water from getting in the brick wall cavity.

Should I be concerned?

These are pictures of the home we're building with the drip edge above the trim band but no flashing between the trim band and the brick:




These are pictures of a home in our area that did include the drip edge above the trim band and the flashing between the band and the brick wall:




I read about IRC 703.8 and UBC 1402.2/1405.3 in other posts here. Would the construction of our brick/siding pass that code?

Thanks for any advice... Jay
