Q

When does a project trigger an ADA compliance requirement?

A

New buildings require accessibility if: they are (1) places of public accommodation (businesses with a public-facing entrance like banks, hotels, restaurants, doctor’s offices, etc.) or (2) commercial spaces that need to be accessed by people with disabilities.

Renovated existing non-compliant buildings require accessibility if: (1) a primary function area is part of the alteration (the teller station of a bank, the lobby of a hotel, the dining room of a restaurant, or the waiting room of a doctor’s office). . . if making the room accessible will exceed 20% of the total cost of the building alteration, then the ADA requirement is considered “disproportionate” and you can cap your accessibility-related spending at 20%, provided you make ADA alterations in this reasonable order of priority until you hit 20% of your budget: entrance; route to the primary function area; at least one unisex restroom or one restroom for each sex serving the area; public telephones serving the area; drinking fountains serving the area; other elements.

86
Q

What is the rule with fire separation distance from neighboring buildings?

A

If your exterior wall has a fire separation distance from the neighboring building greater than 5’, your fire rating only
needs to account for interior fire exposure.

If your exterior wall has a fire separation distance from the neighboring
building less than 5’, your fire rating must account for both interior and exterior fire exposure.

87
Q

What is a planned use development?

A

developments are agreements made typically between a city/town council and a developer in which the
council agrees to change their zoning rules for the developer if the developer does something that the council wants.
Similar to overlay districts but here the ask is of the governing body from the developer for an exception for a specific
(large) site, instead of from the city to all developers for a predetermined zone.
