A practical approach is to contact the property manager directly rather than relying on front-desk staff. Explain clearly who you are, what you want to photograph, when you’d like access, and how the images will be used. If possible, ask for an appointment so you can discuss it professionally.

To improve your chances:

• present your purpose clearly
• be polite and specific about your project
• offer samples of your work
• have any needed permission or release forms ready
• be prepared to sign liability paperwork if they require it
• get written permission before shooting

In short: identify the decision-maker, ask directly, explain your project, have paperwork ready, and get everything signed before you go up to shoot.
