I wouldn't limit it to roof as wind and water can damage other areas of the home..what if a window was left open and the interior now has water damage etc...Did you already bind your insurance (likely not if you are two weeks out) So there may not be a reason for them to dictate you get it reinspected. 

If your contract doesn’t state terms for additional access, then I understand his concern, maybe ask if you can video the interior, although most tenants won’t want that.

Does anyone have recommendations for ADU design and construction companies in San Diego county?

Do you like design?

I have done interior ivy walls, ice cream makers, fresh squeeze orange juice, and even converted an outdoor shed into a "Van Gough Art Studio" to give 1 house a leg up.

Maybe have a golf shirt with a customized design or wear a novelty tie that speaks to your personality.

The other half is: excellent finished product design and management at a reasonable cost. 

I just designed and finished installing a 1314 sq foot home.

Hard money loans are often short-term and designed for projects with a clear exit strategy.

It's usually 45-60 minutes instead of 15 however, and a local rep or property manager can be the "designated agent" who is required to respond to nuisance complaints within the given time period.
