@David Krulac Thanks for the invite. I can't come tonight, but would be interested in the future. Is is held every third Thursday?
Regarding Municipal Ordinances, I think the window blocks would be legal in Reading. The two relevant portions seem to be here:
PM 304.17 Guards for Basement Windows. Every basement window that is openable shall be supplied with rodent shields, storm windows or other approved protection against the entry of rodents.
PM 404.4.4 Prohibited Occupancy. Kitchens and nonhabitable spaces shall not be used for sleeping purposes. Basements shall not be used for sleeping purposes unless they conform to the specifications of this code and the required minimum window area is entirely above the grade of the ground adjoining. The basement and bedroom in the basement shall meet the emergency egress requirements of this code, the International Building Code, the International Existing Building Code, the International Fire Code and the International Residential Code as adopted by the City of Reading as applicable.
The first quote seems to imply that basements can have fixed windows. So, if I am reading this correctly (no pun intended) as long as no one wants to put a bedroom in the basement there should be a problem with needing to meet any codes regarding windows.
I am planning to sell not rent, but don't want to limit the purchaser's options if they want to rent. Any more thoughts on this? Should I call the city and ask? I do know I can't bar the windows per a local police officer who came by after the break in.
