Ideally, i would like to be able search on a map and click on properties block to block and find owner information.Any input would be greatly appreciated.

@Alecia Loveless is correct--tenants need access 24/7 to their electric service panel, water and heat, assuming those are individual utilities for each unit. 

It’s a newly renovated 3-bedroom, 2-bathroom home, just one block from the ski slopes and four blocks from downtown.The current owner has been renting it out for $30,000 per month during the peak winter and summer seasons.

This Wikipedia page gives different wall types and how well they block sound.  

@Jennie Berger The RS-3 Zone allows for Single-Family residences & 2-Flats as "Permitted Uses"; however, the RS-3 Zone still requires 2,500 sq.ft. of lot area per unit (i.e. 5,000 sq.ft. for a 2-flat) unless the lot meets the exception for the characteristic of the block as previously mentioned by Nicolas; then it can be reduced to 1,500 sq.ft. per unit in order to construct a 2-flat.

Its about 8 blocks from the football stadium.  

I currently live Levittown and a house around the block from me is on the market for 1.5m.

I am just out side of Elkhorn, WI and selling our property the is 5 blocks from the lake.

The city operates on a block-by-block basis, and understanding those nuances takes legwork—or working with someone who truly knows the area.

But H&R Block was "with Watson" at least as way back as 2018!
