Planning an Event in Northbrook, IL: Backyard and Banquet Rentals
Plan a Northbrook backyard party or banquet with a yard zone map, tent sizing, seat counts and chair estimates, from graduation parties to weddings.

Northbrook is a residential northern suburb with generous lots, mature trees and plenty of homes that host graduation parties, anniversaries, holiday gatherings and weddings in the backyard. It also has banquet space and a park district. When you host at home, the yard becomes the venue, so the best plan starts with a map. This guide shows how to build one and size the rental order.
Map the yard into four zones
Most backyard events fall apart not because of the chairs, but because of flow. People bunch at the bar, the buffet blocks the path and the dance area sits on a slope. Zoning prevents this.
The drawing shows eight tables inside the tent; add two more on the patio for 80 guests. Our tent size guide and string light layouts help you finish the plan.
Sizing the tent
A common planning rule gives about 10 to 12 square feet per seated guest at rounds, and 15 or more when you add a buffet or dance floor inside the tent.
| Guests | Seating type | Rough tent size |
|---|---|---|
| 40 | Seated at rounds | 20 x 30 ft |
| 80 | Seated at rounds | 30 x 40 ft |
| 80 | Seated plus dance floor | 40 x 40 ft |
| 120 | Seated plus buffet | 40 x 60 ft |
These are planning ranges. A tent company will confirm sizes, and the village will set permit rules. In the Chicago area, many villages require a permit or inspection for tents over a certain size; ask the Village of Northbrook what applies to you, and read our permit guide for questions to ask.
Choosing chairs for a backyard
Pick chairs that look good on grass and in photos.
- Cane-back chair. A woven back adds texture. About $12 to $16.
- Rattan garden chair. A relaxed, natural look. About $12 to $16.
- Cross-back chair. The all-rounder. About $8 to $11.
- Teak garden folding chair. The budget choice for big crowds. About $5 to $7.
Mixing styles can work if the color is consistent. See our guide to boho wedding chairs for pairing ideas.
HOA rules and neighbors
Many Northbrook neighborhoods are part of homeowner associations or have informal rules. Check for limits on tents, noise and parking. Tell your neighbors in advance, share an end time and give them a phone number. A friendly note often avoids a complaint. Also check where guests will park; narrow streets may fill fast, and some blocks have restrictions.

What a Northbrook party costs, in categories
Your total comes from several parts. Chairs have published estimates: for 80 guests, 84 garden folding chairs cost about $420 to $590 and 84 cross-back chairs about $670 to $925. Tables, linens, dishes, glassware, tents, lighting and dance floors vary by quantity, so ask for a quote. Delivery and setup fees depend on access and distance. A written, itemized quote lets you compare options and cut what you do not need.
Rain, heat and bugs
Plan for the weather you can predict. In summer, shade is the first need: a tent with open sides, a large umbrella or the shadow of a tree line. Use fans or cooling for peak afternoon hours, and keep water available. In fall, evenings drop quickly, so bring wraps or heaters (check clearances with the tent company). In spring, the ground is wet, so use flooring under the tent or choose a patio. Bug control matters at dusk near wooded lots: citronella candles or fans help, but keep open flames away from tent fabric, and ask the tent company about fire rules.
Setting a realistic budget
Make a list of every category: chairs, tables, linens, tableware, glassware, tent, flooring, lighting, restrooms, staffing. Rank them by guest impact. Guests notice seating comfort, food and drinks, lighting and restrooms; they rarely notice napkin folds. Spend first on what guests touch. Then ask for a quote and compare itemized lines. If you must cut, cut the extras that serve few people.
