Hello JC,I am not an expert in DC specific zoning but I have a lot of experience with the zoning code in Charlottesville VA. 

I tried giving someone a referral code once, and my post was removed because I’m not a “Pro” member, so not allowed to receive any compensation here. 

For individual properties, we've recently started using a QR code system for wi-fi and email capture to save on costs.

Depending on the zip code I was wondering could I gamble with them on a fix and flip or brrr.

Then I helped friends or people who I was recommended to with basic remodel suggestions while staying up to code.

you choose one pay for it and they provide them.What I found out is they just send over the plans with no updates to current codes so we submit then and get check sheets sometimes 3 or 4 and takes 90 days to get approved instead of them understanding the new codes updating the plans before giving them to us.And to be fair to the architect we can send in the same plans and depends on which examiner gets them some will fly through others come back with check sheets that an examiner frustration issue.

The plumbing industry has so many different type of materials and codes that most customers simply don't know what to buy and get frustrated after so many trip trying, because they keep buying the wrong thing.

- You can find this out by going to Zillow, selecting your Zip code or Neighborhood, and looking at current rental listings.

The other thing to consider is the age and if you add a second floor will the entire structure need to be brought up to code for hurricane and wind.I live in a neighborhood where the homes are older (not in florida) and the foundations are hollow core CMU and adding a second floor would not be feasible due to soil bearing.

They wanted upgrades to electrical panel that was upgraded in 2009 to current code  (arc fault breakers) they said they would walk , I said good bye .
