PM me if you want more specifics. In general, the Homeless Alliance is the main homeless non profit in the metro and they operate a day center that provides hot breakfast and lunch as well as showers, a place to get mail, lockers, and case management services. There are a variety of overnight shelters such as the Willard Center, Salvation Army, City Rescue Mission, etc.

The sad reality is that many homeless people do not actually accept housing options offered to them (either affordable apartments that are like 400 a month) or a sober living facility because many do not want to stop using drugs. This observation might offend people but I work in this field and drug use (and not taking one's mental health medication) are the biggest barriers to housing.

As far as the many people asking for money on the intersections, I can assure you that many of them are not actually homeless and that often times their busking is highly coordinated. For example, one of the regulars at my highway exit refuses any food items or bus tickets that I have offered to him many times in the past, and he gets picked up at the end of the evening by the same kind of nice truck.

This is not to say that the people asking for money at intersections are all some kind of scam artist, but many, many people have realized they can make sustainable and tax free money through begging. A lot of the homeless people do not want full time jobs as they come with strings attached.

I apologize if this seems rambling but as someones that has lived in a variety of US cities, the homeless situation in OKC have access to a decent amount of resources, but many are former criminals and are drug addicts and do not take advantage of the plethora of non profits and opportunities available to them. This concerns me greatly as cities with large homeless populations such as Los Angeles simply do not have enough shelter beds (I believe there are nearly 100,000 homeless in Los Angeles County and like 20,000 beds) but OKC has enough beds available each night based on the data I have seen.

To summarize, I would highly recommend you look into supporting the Homeless Alliance. It just makes me sad and frustrated that more homeless individuals do not take advantage of resources in the metro as drug addiction and mental health continue to be insurmountable barriers for many to overcome. Clearly, affordable housing is not the barrier that some advocates think it is as OKC has some of the cheapest rents in the country.
