Adding parking - how much?

Question

Hoping for an estimate of how much it would cost to pave a current grass area that's about 50x80. I also might have to pay the paving of the bigger parking adjacent lot (100x150) in order to gain right of way access.

Also, how many parking spots can I fit into a 50x80 area? Keep in mind it's in Boston, so will ned a place for snow.

Prices are regional , you may also need storm water management for run off . Depends on how much dirt needs to be removed .   But roughly to get an overlay on existing asphalt figure $6.00 per sq ft .  New lot with dirt work , base stone then asphalt $15 to $20 a sq ft .   Just rough numbers

I've been out of commercial construction for a while now, so I may be mis-remembering, but here in Kansas City you could get new asphalt pavement laid (including base rock/fine grading) for $50 to $70/SQ ($5.5 to $7.5/sf).   Curb I believe was $15 to $25/lf.

I'm assuming since 50x80 is relatively small it will likely carry a premium & be on the higher end.

You also need to consider your curb and gutter, storm water, retaining walls, striping costs, signage, exterior lighting, landscaping & trash enclosure?

When you add all of that stuff up it wouldn't shock me if it was $50k to $100k

I will talk about parking designs in general.  @Matthew Paul addressed the cost.  General parking lot layouts are parking spaces ranging from 8 x 18 to 9 x 19.  Aisles typically require 12 feet in width for each direction.  Vehicles that can come from either direction to park will require a minimum of 24 feet in width.  The angle of the parking spaces will effect the dimensions as well.  Don’t forget accessible parking spaces are based on a percentage of parking provided.  Check the cities website for parking criteria.  It can vary from city to city.

Good Luck.

So for a 50x80 parking pad you are looking upwards of $80,000?!? They encrusting it in diamonds or something? That is insane.  I've seen a similar area paved for about $10k

In MA and some other areas you will be dealing with how much impervious area there is on the property. There is a limit, if you are above it you may be able to use a surface the water can get through.   Local building code should contain the info you are looking for.

@Alan Miegel in Cambridge I was just given a quote the other day of $15 a square foot for parking pavers. Price included demo of concrete.
